8.0 CONSTRAINTS/CHALLENGES

Below is a summary of constraints of all the Centres;

1. Lack of office accommodation, furniture and other office equipment

2. Funds to complete refurbishment of the Central Waste Processing facility

3. Funds to carry out detailed site investigations for the Borehole Disposal Project

4. Lack of National Radioactive Waste Management Policy, Strategy and Regulation.

5. Financial difficulties being faced by the Institute is hindering research activities; it is therefore

recommended that the Institute could possibly design strategies which closely involve more

stakeholders who can support the local components of research and development.

6. Lack of internet access. Staff mostly use their personal internet modems which often

face connectivity challenges as a result of network problems and the location of the

offices. Provision of internet access will be of great help.

7. Lack of IDD telephone: During installation of the accelerator it may become

necessary to contact the manufacturers. Therefore the need to an IDD phone is crucial.

The accelerator centre needs at least 2 IDD phones for effective operations.

3

8. Lack of furniture in all the centres.

9. Lack of personal computers for staff.

10. The frequent power outages posed a challenge to scientific work.

11. National Data centre requires additional workstations to receive and analyze seismo-

acoustic and spectra data.

12. The geophysics applications unit currently does not have any equipment and therefore

has to rent equipment before carrying out any geophysical service for the Institute.

The unit therefore urgently needs equipment for its smooth operation.

Pumping Test Conducted

on Two Investigatory Wells for the Borehole

Disposal of Disused

Sealed Radioactive Sources (BOSS) at

GAEC site, Ghana.

Pumping test was carried out on two investigatory boreholes on Ghana Atomic Energy Commission’s (GAEC) premises

earmarked for the disposal of Disused Sealed Radioactive Sources (DSRS) to determine the aquifer characteristics such as Transmissivity and Storativity. Data generated from the pumping test were analyzed with Cooper-Jacob Time-

Drawdown Method and Theis Recovery Analysis for confined aquifers. Residual-drawdown analysis generated a

transmissivity value of 0.144m2/day (1.55ft2/day) whiles the data was found to be insufficient for a comprehensive analysis using the Coober-Jacob Method. The recovery level within the first hour was estimated to be as high as 22.02

m/hr. A very strong evidence of aquifer system interconnectivity was found from the results of analysis between BDS1

and BDS2 which might be a plus for the post-closure safety assessment of the Borehole Disposal System to monitor possible compromise of the multiple engineered barriers and the consequent migration of radionuclides. Adequate and

reliable groundwater samples were also obtained during the test for geochemical site investigation studies. There is

however the need for further longer duration pumping tests to be conducted on these two boreholes for conclusive results and analysis.

Measurement of radon

concentration in water sources in Pwalugu in

the Upper East Region of

Ghana

Radon is a naturally occurring colourless, odourless, water-soluble gas produced by the radioactive decay of radium.

Chronic exposure to Radon is recognized as health risk. Ingested water with elevated levels of Radon can present risk for developing internal organ cancers. Ten water samples collected from four different water sources (borehole, pond,

hand – dug well and river) in Pwalugu and its surrounding environment has been analyzed using the Gamma

Spectrometry System. The radon concentration varied from 29 ± 1.1 to 38 ± 2.1µBq/L. These values fall below the maximum concentration level, of 0.148Bq/L proposed by the US EPA. The highest concentration was recorded in

borehole samples due to the nature of the geology and lack of loss of radon due to aeration. The calculated annual

effective dose by ingestion varied between 2.774 × 10-7 and 2.117 × 10-7 Sv/y which is below the recommended value of 1mSv/y.

Multi-elemental assay of

investigatory boreholes rock samples using NAA

technique

Multi-element assay of rock chips samples from two investigatory boreholes using neutron activation analysis (NAA)

technique has been undertaken in this research. The boreholes were drilled on the north eastern flank of the Ghana Atomic Energy Commission (GAEC) site for the purpose of investigating the geology, geochemistry and hydrology of a

site which has been earmarked for the construction of a radioactive waste disposal facility. This research is aimed at

assaying multi-elemental composition of the rock chips samples which were collected during the drilling of the boreholes so as to gain understanding of the chemical and mineralogical characteristics of the bedrock of the site. Data

from this research is meant to be used for the development of geologic conceptual model for the site. The geologic

conceptual model is needed for safety assessment which is an important component of Safety Case. The Safety Case document is a requirement for the implementation of the Borehole Disposal Concept (BDC) project; the project under

which the disposal facility is being implemented. The Safety Case document provides confidence to stakeholders (e.g.

government officials, regulatory authorities, general public, etc.) that the disposal facility will be sited and engineered to ensure safety of human health and the protection of the environment over long timescales.

Refurbishment and

modernization projects at

the Ghana Research Reactor-1 (GHARR-1)

The Ghana Research Reactor-1 (GHARR-1) Facility is a low power research reactor with a rated power of 30 kW. It

uses highly enriched uranium (90.2%) as fuel, light water as moderator, coolant and biological shield and beryllium as a

reflector. GHARR-1 attained criticality on December 17, 1994 and commissioned on 8th March, 1995. It has since been operated successfully and continuously for nineteen (19) years. The reactor was built with an intended life span of 10

years but within the limits of proper ageing management, refurbishment and modernization projects it can go beyond 30

years. To fully utilize and extend the operational life span of GHARR-1, some ageing management programmes, refurbishment and modernization projects have been undertaken and implemented in the routine practices and

operational procedures at the facility. This paper presents the completed and intended refurbishment and modernization

projects at the Ghana Research Reactor-1. Also a brief discussion on ageing management issues is considered.

Preliminary study on climate change a

potential factor in

elevating levels of indoor radon gas

Climate change issues should be critically dealt with since it is possible to elevate indoor radon gas. Therefore, soil gas radon have been monitored for a period of three months (August-November) using nuclear track detection technique

with ambient temperature in twelve sample pits with depth of 75 cm and 50 cm respectively on a land of about 50 m x

50 m at Ghana Atomic Energy Commission, Kwabenya. The geometric mean soil gas radon concentration in the 75 cm sample pits ranged from2.11 – 17.13) kBq/m3. That of 50 cm sample pits ranged from (1.07 – 11.85) kBq/m3 .The

average ambient temperature ranged from 28 oC - 31oC. Soil gas radon concentration increased with ambient

temperature, this may increase indoor radon gas level through temperature changes in outside and indoor air

Nuclear

power: the last

and only reliable resort

The development of nuclear energy has been shown to be Ghana’s last and only resort to address the country’s energy situation. An analysis of all energy sources if harnessed will be insufficient to meet the country’s projected demands. Ghana’s net grid electricity consumption is predicted to grow from about 6,900 Gigawatt-hour (GWh) in 2000 to about 18,000 GWh by 2015, reaching about 24,000 GWh by 2020. Currently the country has a total installed capacity of approximately 2800 MWe with an available capacity approximately 2400 MWe. Hence, there is a need for significant investment in new electricity generation. Nuclear power is the most environmentally benign way of producing electricity on a large scale. In addition, the human resource needs for implementing and utilizing nuclear power technology generally lead to high intellectual capital gains for the country. Thus would lend to an increased economic growth rate, faster rate of industrialization and increase human resource expertise. With the current limitations of other energy sources such as hydro power, thermal and gas, Ghana has no better choice than to jump unto the nuclear bandwagon like other developed countries.

Banini, B.K and Ekow-Mensah, B. Repairs and Calibration

of Spectrophotometer

W1 lamp of VIS/UV-spectrophotometer was replaced and photometric alignment was carried out. To ensure that the

spectrophotometer satisfied standards for accreditation of laboratories as in ISO 9001 in section: 4.11 require inspection,

measuring and equipment testing; likewise, IEC 17025: 2005 in section: 5.5.2 requires the equipment to be calibrated or

verified before being put into use. Hellma secondary calibration standards (4026 - Holmium oxide - Filters: F0, F2, F3, F4 and filter didymium oxde - F7) have been used in order to verify if errors in the laboratory have been close to the 2%

margin. The set of secondary calibration standards permits to check the accuracy of the spectrophotometers used in

research for both the absorbance in the visible spectrum (at 440, 465, 546,590 and 635 nm wavelengths) and for the wavelengths (270, 280, 300, 320 nm) of the ultraviolet light. Filters (F0, F2, F3, F4 and F7) are stable and do not suffer

the influence of temperature (the influence is negligible), the F0 filter was being used as a blank. All the percentage

errors obtained after the calibration were from minimum percentage error of 0% to maximum percentage error of 0.7%

10

which within the acceptable range for scientific works.

Indicator polychlorinated

biphenyls and

organochlorine pesticides in the Weija

Lake and their health

implications.

The occurrence, levels and sources of organochlorine pesticides (OCPs) and indicator polychlorinated biphenyls (PCBs)

in the Weija Lake are presented and levels revealed varying concentrations in the water and the sediments. Liquid-liquid

extraction with hexane was used for the extraction of the compounds from the water samples while sediment and fish samples were sonicated on ultrasonic bath with hexane/acetone (3:1) solvent system. The extracts were then cleaned up

with florisil and quantified on a micro-capillary gas chromatography equipped with electron capture detector. In all, five

indicator PCB congeners namely, PCB # 28, 52, 101, 138, 180 and fifteen OCPs, α-HCH, β-HCH, γ-HCH, δ-HCH, γ-chlordane, aldrin, dieldrin, endrin, α-endosulfan, β-HCH, endosulfan sulfate, p,p’-DDT, p,p’-DDE, p,p’-DDD, and

methoxychlor were detected. However, the levels of α-HCH, β-HCH, aldrin, dieldrin, γ-chlordane, PCB #118, 153 were

below detection limit in the water samples. In sediments, the mean concentration ranged from <0.01 µgkg -1 to 7.08 µgkg -1 dry weight. Similarly, concentrations in the fish species were in the range of <0.01 µgkg -1 to 32.40 µgkg -1.

Generally, the mean levels of the organochlorines in the Weija water and sediments were below quality guidelines set by

WHO and other international bodies. Estimated daily intakes (EDI) of organochlorine as a result of consumption of fishes from the Lake for children and adults have been presented and EDIs for children ranged from 0.002 µg/kg to

0.176 µg/kg and those for adults were from 0.0011 µg/kg to 0.0892 µg/kg. Analysis of the EDI data revealed that daily

exposures of OCs to children on consumption of the fishes are higher than daily exposure to adults. EDIs were however, far below reference doses (RFDs) recommended by United State Environmental Protection (USEPA). Consumption of

Clarias gariepinus among the fishes provided the highest risk of organochlorine exposure. Risk assessment in terms of

carcinogenic and non-carcinogenic effects on humans on consumption of the fishes have been evaluated and analyses

revealed that eating of Tilapia zilli, Tilapia nile and Tilapia galilaea from the Weija Lake present no risk of carcinogenic

effect. However, more than one in one million of the population on consumption of Clarias gariepinus can get cancer as

a result of HCHs contamination.

Status of some heavy

metals contained in

imported nail polish and lipsticks on the Ghanaian

market

Imported cosmetic products (i.e. nail polishes and lipsticks) mainly from China and the United States were purchased on

the open market in an urban market in Accra and analyzed for the presence of heavy metals including cadmium, cobalt,

lead, nickel, chromium and manganese. While the concentrations of nickel were below detectable limits in all the samples, the concentration of lead in the lipstick samples exceeded the allowable limits as prescribed by the Health

Canada Draft Guidelines on Heavy Metals in cosmetics.

Isotopes of δ2H and δ18O

in rainwater,

groundwater and spring water in a mountainous

region of Ghana:

implications with respect to groundwater recharge

and circulation

The Amedzofe Mountains is one of the highest human habitations in Ghana. Groundwater and spring water are the

perennial source of water supply for domestic and other purposes. In this study, the characteristics of δ2H and δ18O in

rainwater, groundwater and spring water have been used to understand the groundwater dynamics and recharge in the area. The local Meteoric Water Line (LMWL) using all the rainfall events gave an equation with the best fit line of δ2H

=7.32 δ18O + 8.20 (n = 113; r2=0.94). a further development of LMWL for heavy rainfall events greater than 10 mm, 20

mm and 30 mm orient the slope closer to the Global Meteoric Water Line (GMWL). The distribution of the stable isotopes of the rainwater is mainly influenced by the rainfall amount with temperature having minimal effect. All the

spring water and most groundwater plot around the global meteoric water line, implying groundwater and spring water is

of meteoric origin with some groundwater showing evidence of isotopic enrichment. The Chloride Mass Balance (CMB) and δ18O shift methods gave mean groundwater recharge of 10.70 and 8.39 % of annual rainfall respectively. The CMB

estimated mean spring water recharge of 26.46 % while the δ18O shift method gave a recharge of 25.06 % with

11

calculated altitude of recharge ranging from 614 to 1484.31 m amsl. The use of the stable isotopes provide unique

additional information that, significant groundwater recharge takes place in the months of March, June and August.

A study of laterite characteristics in relation to fluoride adsorption from fluoride-contaminated water

The effect of the characteristics of laterites on fluoride adsorption from solution was investigated using three laterite soils from three locations in the Upper East Region of Ghana namely Agamolga, Balungu and Dua localities in the

Bongo District. The investigations showed the minerals were mainly intimately associated which could have influenced

charge development on the mineral surfaces and therefore affect the influence of solution pH as a factor for fluoride adsorption. The studies also showed that differences exist in the behaviour of the laterites during fluoride adsorption,

which is due to the mineralogy of the laterites. Fluoride uptake by the laterites was initially rapid, which could be

attributed to the aluminium silicate minerals and the amount present in the laterite and involve the exchange of OH- ions with F- ions. Thereafter, fluoride uptake was dominated by surface bond formation on the iron oxide minerals.

The use of Hydrochemistry and

stable isotopes(δ18o, δ2h)

to investigate surface water and groundwater

quality in the Lower

The hydrochemistry and stable isotopes of surface and groundwater have been studied to examine the overall water quality status of the Volta River and shallow groundwater in the Lower Volta Basin (LVB).The pH values ranged from

4.9 to 7.5 for surface water (SW), demonstrating mild acidic to alkaline conditions. The pH values for the groundwaters

(GW) range from 3.6 to 7.8, suggesting acidic to alkaline waters. The nitrate concentration ranges from 0 to 3.0 mg/L for surface water and 7.3 to 433 mg/L for groundwater. The nitrate values in SW are comparatively lower than nitrate values

in GW for the entire area. The hydrochemical facies for the groundwater samples show four main water types, namely

NaCl, (CaCl2, MgCl2), CaMgHCO3 and the non-dominant water type. The predominant hydrochemical facies is NaCl, whereas CaCl2, MgCl2 and CaMgHCO3 water types occur to a smaller extent in the area. Mineralisation (salinity) of the

12

Volta Basin of Ghana

groundwaters, which was initially not considered in the research objective, has become a key issue worth mentioning.

Possible processes responsible for the groundwater mineralization include halite dissolution, cation exchange and seawater intrusion. Stable isotope composition of the shallow groundwaters shows that GW in the north east of the study

area (Sogakope), GW in the south west (Ada) and the Volta River appear to define a mixing line with multiple end-

members.

Determining groundwater quality

through groundwater

major ions chemistry and microbial assessment in

the Adenta-West suburb

in the Greater Accra region of Ghana

The data acquired is used in this study to assess the quality of groundwater in the Adenta west municipality. Groundwaters are showed strong acidic character with pH values in the range 3.13 to 6.22. The pH of all the sampled

water was < 6.5, and therefore outside the WHO recommended limits. The conductivity values are in the range 327--1 -1 suggesting the groundwaters are generally fresh. The groundwaters are

moderately hard to very hard with only 40% of the samples representing soft waters. Groundwater quality is excellent

with respect to major ions (Ca2+, Mg2+, Na+, K+, HCO3- SO4

2-, Cl-) as they fell below their respective WHO guideline

limits for water potability. However, results of microbial analysis of total coliform, faecal coliform and Escherichia coli rendered some of waters unsafe for human consumption. Total coliforms in the groundwater samples ranged from

5.40×102 to 6.87×102. Faecal coliform counts ranged from 3.66×102 to 4.50×102 whiles Escherichia-coli ranged from

1.35×102 to 1.98×102. WHO Guidelines stipulate that there should be no detected coliform in drinking water and therefore, any of the samples with detected coliform is not suitable for drinking purpose unless it is being disinfected.

The presence of these microbial bacteria was attributed to the close proximity of pit latrines to the hand-dug wells.

Hence, guidelines and regulations about the use of such water require revision and indicate the necessity to disinfect in order for these sources to provide communities with potable water. The study demonstrated how households in the

Adenta West suburb are vulnerable to contracting waterborne diseases when they depend solely on the groundwater

from the suburb as their sole source of drinking water.

Evaluating the suitability

of groundwater for

irrigational purposes in some selected districts of

the Upper West region of

Ghana

Groundwater is a very important asset to the people of the Upper West region of the Ghana where majority of the people

are farmers. Groundwater serves as the most reliable source of water for their domestic and agricultural activities. This

study was aimed at assessing the suitability of groundwater for irrigational purposes in some selected communities of five (5) districts where farming activities are very intensive. Twenty-three (23) groundwater samples were collected and

analysed for major anions and cations. Physicochemical parameters such as Electrical Conductivity (EC) and Total

dissolved solids (TDS) were also measured. From the results of the analyses and measurements, the suitability of the groundwater for irrigation were evaluated based on the TDS, EC, Percentage Sodium (%Na), Sodium Adsorption Ratio

(SAR), Permeability Index (PI), Residual Sodium Carbonate (RSC), Magnesium Adsorption Ratio (MAR), Kelly’s

Ratio (KR) and Chloro-alkaline Indices (CAI). U.S. salinity laboratory diagram and Wilcox diagrams were also applied. The EC results show that the groundwater in the study area can be classified as none and slight to moderate. According

to the US salinity diagram, groundwater in the study area falls within the Low salinity-Low sodium hazard and Medium

salinity-Low sodium hazard class. The % Na and the resulting Wilcox diagram also classify the groundwater as Excellent to good and good to permissible. The groundwater in the study area is generally good for irrigational purposes.

However, there are few instances which are problematic and would require special irrigational methods.

Evaluation of metal composition of

phosphate fertilizers in

Ghana

The elemental composition and possible sources of metals in phosphate chemical fertilizers used in Ghana were determined. The fertilizers used in this include Rock Phosphate (RP), Triple Super Phosphate (TSP), Mono Ammonium

Phosphate (MAP), Diammonium Phosphate (DAP), and NPKs in varying proportions. Analysis of these metals of

interest was carried out with Flame Atomic Absorption spectrometer (FAAS). Metals such as Cr, Co, Cu, Cd, Mg, Mn, Pb and Zn were possibly generated by the dry milling process of phosphate rocks in the fertilizer manufacturing

factories. The chemical reactions within the factories probably participated in the metal loads. Triple Super Phosphate

(TSP) had relatively high levels of metals in the fertilizers.

Groundwaters from basement aquifers in the Ochi-Narkwa basin of the Central Region together with rain and surface waters have been analysed for stable isotopes (δ18O, δ2H and δ13C) and radioisotopes (3H and 14C) to determine sources

of recharge, groundwater residence time and flow path. The mechanism of recharge to the groundwaters is by direct

infiltration of past local rainfall of mean isotopic composition δ18O = -3.8 ‰ V-SMOW and δ2H = -18 ‰ V-SMOW.

Tritium in the groundwaters ranges from 0.05 ± 0.07 to 4.75 ± 0.16 TU. Tritium data revealed that 85% of the

groundwater samples are of modern recharge or young waters. 14C content of the groundwaters range between 9.50 pMC in borehole CR2-50 at Ekumfi Asokwa to 113.56 pMC in borehole CR3-26 at Onyaadze. Evaluation of 3H and 14C data

distinguished three groups of water namely (1) waters characterised by high 3H and high 14C depicting modern recharge,

(2) waters showing a mixture of young and old water and (3) waters showing low 3H and low 14C contents referred to as very old waters and include borehole CR2-50 at Ekumfi Asokwa. The estimated age or residence time of this older water

is 13,920-21,732 years BP based on Uncorrected age, Tamers, Pearson and Ingerson, Mook’s and Fontes and Garnier’s

models. The major flow direction is east-west. Groundwater residence times in the basement aquifers of the Ochi-Narkwa basin show that groundwater abstraction is sustainable and requires that the recharge areas are protected from

contamination.

Assessment of the reliability of the micro-

current amplifier of

Ghana research reactor-1(gharr-1)

The two control systems of GHARR-1 were coupled with separate micro-fission chambers to measure the current pulses of the neutron fluxes in core. The Micro-Computer Close Loop System (MCCLS) and Control Console (CC) readings at

a preset of 5.0 x 1011 n/cm2s were 6.42 x 1011 n/cm2s and 5.0 x 1011 n/cm2s respectively. After the replacement of new

MCCLS, the two consoles were reading same values with one fission chamber instead.

The performance of the micro-current amplifiers in the two independent control instrumentations was investigated. The

Keithley instrument was used to source six (6) different quantities of inverting current values between 1 nA to 20 μA

into the inputs of the current micro amplifiers of the two control systems to assess their stability and linearity. The results show that the voltage values registered on the measuring meters of the control consoles a correction factor of 1.2

was adopted to enable the two control systems to measure the same neutron fluxes.

No correction factor is needed anymore for data (quantitative) analysis for neutron activation analysis (NAA) work.

Ageing management, obsolescence and

refurbishment of gharr-1

structures, systems and components (SSCs)

The Ghana Research Reactor-1 (GHARR-1) Facility is a Miniature Neutron Source Reactor with a rated power of 30 kW. GHARR-1 was commissioned on 8th March, 1995. It has since been in operation. The facility is being operated

using the Micro-Computer Closed Loop System (MCCLS) and original Control Console (CC) for the past 19 years. The

control systems have undergone modifications, upgrading and refurbishing since their construction in order to meet the requirements for higher performance. The Instrumentation and Control (I & C) systems are important for reactor safety

to guard against abnormal occurrences and reactor control involving start-up, shutdown and power regulation.

14

The routine practices and operational procedures have been set out with clear emphasis on ageing management

programme at the facility. Due to unavailability of spare parts, especially, electronics components for replacement in case of components failure; the ageing management programme adopted a system of listing various components and

finding their alternates or equivalents. Little alterations and modifications are made to some component equivalents in

particular circuits in the control console, pneumatic control system and radiation monitor in the control system. A high voltage circuit in the IAEA TECDOC - 530 was adopted to replace broken down radiation monitor circuits in the control

console. Methods have been developed to test the IC components to determine their state of function in the circuits of

operation. This enabled us to change some of the electronic components during maintenance sessions. Regular purification of the reactor and pool water are performed to mitigate corrosion. This paper outlines the ageing

management programme and mitigation practices. Strategies for ageing management; including periodic safety reviews,

design features for components and unit replacement, and succession planning. Information sharing with other operating organizations is one of the means considered by GHARR-1 to attain excellence.

Non-Destructive Evaluation of Steam Turbine Generator Using Liquid Penetrant Technique.

Critical gas turbine rotating component, such as turbine blades, compressor disks, spacers and cooling fan blades are

subjected to cyclic stresses during engine start-up, operation and shut-down. The lifetime of these components are

usually established on the basis of probabilistic crack initiation criterion for a known fracture-critical location. Therefore, periodic inspections are carried out to detect the probable cracks and prevent sudden failure. The dye

penetrant testing basically revealed the cracked, fractured and sound parts of the steam turbine blades which did not

completely fracture during the inspection period

Investigation of feed dynamics in clinker grinding mill by residence time distribution method

Residence time distribution (RTD) analysis has been identified as the best experimental and classical tool for studying the performance of non-ideal chemical reactors and industrial circuits. In this study, Residence time distribution (RTD) method was used to investigate feed dynamics in clinker grinding mill. Grinding of clinker during cement production is energy intensive and consumes about one-third of the power required in cement production processes. This makes grinding of clinker an important process which needs to be optimized during cement production. The data was collected by introducing 40mCi of liquid Au-198 as a tracer in the feed at the mill inlet. The gamma signal was determined with thallium activated NaI detector placed at the mill outlet. RTD curve of the mill was generated from which the Mean residence time (MRT) was evaluated using the method of moments. The experimental MRT was 22.7 minutes and the theoretical MRT evaluated from plant parameters was 55.3 minutes. “Perfect mixing cells in series” and “perfect mixing cells in series with exchange” models were used to model the mill. The feed dynamics in the mill was best described by the “perfect mixing cells in series with exchange’ model which fitted well with the experimental outlet response curves of the mill.

The material properties for the irradiated structural core components of Ghana Research Reactor 1 (GHARR-1) are to be established using computer codes MCNP and Exifon. The

evaluation of the irradiated material properties will help minimize unpredicted failures of

core components and avoidance of lengthy and costly shut downs of the reactor. The MCNP code is used to determine the neutron flux at all sections of the reactor and the EXIFON code

for the determination of the type of reaction in the reactor materials.

Over the years there have been additions of top beryllium shims to compensate for depletion of the uranium 235 fuel. The addition of the top beryllium shims were not accounted for

Baidoo I.K Optimization and effective elemental

analysis using low power

Laboratory

This works discusses the effective and optimize design of activation protocols for low power research reactors in cognizance with the practical experience of GHARR-1 NAA laboratory. While the experimental results are peculiar to

GHARR-1 NAA facility, it can be replicated elsewhere, where the facilities may be similar. The activation protocols

were designed to enhance maximum element detection, reduce radio isotope interference, improve measurement accuracy and precision, and most importantly reduce measurement turnaround time. Key advantage was taken from the

different half-lives of radionuclide and independent different gamma energy emission for the same radionuclide.

Cognizant of the limitation of RRs to barely produce enough activation for elements with relatively long-lived half -

lives, it is imperative that steps are taken after activation to achieve optimum counting statistics; in this respect, various decay times have been tested for a fixed activation period in order to ascertain optimum statistics for various elements.

A preliminary

decommissioning plan of

the Ghana Research Reactor-1 (GHARR-1)

Worldwide many nuclear facilities which are no longer useful will need to be decommissioned; although there are other factors that lead to decommissioning. Other factors that might warrant a permanent closure and subsequent decommissioning of the nuclear reactor could be due to change in government policy or due to damage from natural and man-made phenomena. During such process safety standards might be adopted for the protection of public health, life and property in the development and application of nuclear energy for peaceful. In this way the International Atomic Energy Agency (IAEA), seeks to guide and recommend, through publications, guidelines for performing of activities of decommissioning, for both nuclear power plants and research reactors, with special attention to countries that do not have a framework regulatory legal that sustain the activities of decommissioning purposes. In like manner the IAEA recommend that decommissioning planning should be part of all radioactive installation licensing process. When the GHARR-1 facility is no longer useful as a research tool, decommissioning will be required. The aim of this document is to develop a preliminary plan for decommissioning of the GHARR-1, taking account the technical documentation of the facility Safety Analysis Report (SAR), the standards related to nuclear activities of the Radiation Protection Institute (RPI), as well as the recommendations and instructions of the International Atomic Energy Agency regulations. The preliminary decommissioning plan consists of the presentation of the actions and procedures required as well as the strategies to be adopted for the shutdown of the facility under the technical and administrative requirements, with the aim of focusing on the safety aspect of workers, the general public and minimizing environmental impacts. Other relevance aspect of this document is to attend the basic regulatory requirements of RPI during the planning and implementation of decommissioning of GHARR-1.

Ground deposition assessment of radionuclides following a hypothetical release from Ghana Research Reactor-1 (GHARR-1) using atmospheric Dispersion Model

With the sustained development in computer technology, the possibilities of code capabilities have been enlarged substantially. Advanced safety evaluations and design optimizations that were not possible few years ago can now be performed. There is a challenge today in assessing radiological dose from nuclear reactor using a more reliable computer tool in addressing the released radionuclide to the atmosphere and ground effectively and to compute the dose rates. As such the dealing of atmospheric dispersion of radionuclide release from a nuclear facility has become very imperative. This has enhanced the idea of revisiting the safety features of the existing nuclear plants and particularly research reactors. One of such kind of research reactors whose safety is of concern now is the 30kW Ghana Research Reactor-1 (GHARR-1) which uses a Highly Enrich Uranium (HEU) fuel. In connection with conversion of GHARR-1 from HEU fuel to the use of Low Enrich Uranium (LEU) fuel; assessment of a postulated radiological dose from possible radionuclides released using computer technology is essential. An effective computer model which is based on a reliable atmospheric transport and dispersion theory can help address such drawbacks. Atmospheric dispersion modelling and radiological safety analysis were performed for a postulated accident scenario of the HEU fuel of the GHARR-1 core. The simulation was performed using a reliable health physics atmospheric dispersion code called HotSpot. The HotSpot code which employs a Gaussian plume technique was used to perform the atmospheric transport modeling which was then applied to determine the ground deposition of radionuclides and to estimate the Total Effective Dose Equivalent (TEDE) of release radionuclides. The source term was generated from an inventory of peak radioisotope activities released by using the Oak Ridge isotope generation code ORIGEN-2. The adopted methodology used was based on the predominant site-specific meteorological data. Some selected radionuclides were evaluated to prove whether their release may have radiological effect on the public. Nonetheless, prudence requires assessing the effect on the public during such events. The results indicate that the maximum ground deposition value of 1.5E-04 kBq/m2 occurred at 96m distance and the maximum TEDE value of 1.9E-02 mSv occurred at 93m from the reactor. It was observed that the values were far below the NRC acceptable limit of the 0.1 rem (1 mSv) for the public in a year even in the event of worse accident scenario.

Efforts Made for the Conversion of Ghana’s MNSR to LEU

Ghana Research Reactor-1 is one of the Miniature Neutron Source Reactors in operation outside China, and it has been in operation since it was commissioned in March 1995. The fuel of the reactor is UAl4 in an aluminum matrix and has an enrichment of 90.2 %. The reactor core has been earmarked for conversion from the 90.2 % enriched HEU to about 13.0 % enriched LEU in the form of UO2; hence various studies have been undertaken in pursuance of this course. A Project and Supply Agreement for LEU fuel has been signed by all stakeholders. Currently, UJV/SKODA in collaboration with CIAE is designing a cask which will be used for the shipment of the spent HEU fuel from Ghana to China.

Electrical resistivity characterization of

subsurface condition for

the construction of a proposed office complex

at Anyinase for Ghana

national gas company in Ellembelle district of

western region, Ghana.

Geophysical investigation was conducted at Anyinase, near Asiama in Ellembelle District of Western Region for E.M Geotech Ltd. The main objectives were to establish the existence or otherwise of linear features at depth and the

conductivity/ resistivity of the soil. Consideration was also given for the selection of any anomalous point(s) that could

lead to the drilling of a borehole at the site.

The methodology employed included both horizontal electrical profiling and vertical electrical sounding (VES) using

Abem Terrameter SAS 300C. While the Wenner configuration was used for the profiling, Schlumberger four-electrode

array was used for the VES at seventeen (17) locations on the horizontal profiles. The results of the investigation indicate the site has few linear features and the bedrock is shallow maximum depth of about 11.3m and therefore ideal

for the construction of the Office complex. Low conductivity could occur at shallow to medium depth and medium

conductivity at greater depths at almost all VES locations: A0, A70, A170, B0, B40,B100, C0, C60, D0, D50, D90, E0, E50 and E 80 and these points should be further investigated by shallow drilling to about 10m. Points A0, A70, A170,

B0, D0 and E80 appeared to be at the end of the property and therefore can be drilled for boreholes to avoid any change

in the design of the facility. Points such as A0, A70, A170, B0, C0, C60, C100, D0, D50, D90 and E80 could be considered favorable for test drilling of boreholes. However, some of these points such as C0, C60, C100 D50 and D90

are within the areas for the construction of office complex and therefore cannot be considered for drilling of boreholes.

In terms of providing water for the proposed structure, points A170, B0, D0, E0, E50 and E80 all of which lie at the boundary of the proposed site plan are suitable for the drilling of boreholes. The decreasing order of promising points for

test drilling is D0, E50, E80, E0, A170 and B0. Minimum drilling depth is 41m with maximum of 94m. However, test

drilling must be monitored as drilling proceeds in order not to drill into saline water aquifers. The volume of water required for the office complex shall depend on the yield of boreholes and the projected water demand for the office and/

or housing complex.

The high resistivity nature of both the overburden, alternating layer of rocks and the bedrock gives the soils at the site suggest non-corrosive nature of the subsurface unless influence by sea-water intrusion. Point D50 and D90 are

apparently suitable for electrical grounding at depth not exceeding 4.8m due to their relatively lower soil resistivity

compare to other points.

Strengthening the

Capacity for Infrasound

Monitoring in Africa through CTBTO

With the additional civil and scientific applications of CTBTO monitoring data to signatory States, there is growing

interest by African States towards the purpose of the CTBT. The CTBTO’s Capacity Building Project in Africa aimed at

providing technical assistance to signatory States on the continent for full participation in the monitoring and verification system of the Treaty is commendable. Twenty four African states host seismic, hydroacoustic, infrasound and

radionuclide monitoring stations as part of CTBTO International Monitoring System (IMS) to detect nuclear test

17

explosion events around the globe. In Africa, there are significant natural infrasound sources worth mentioning, these

can serve as potential knowledge-base for improved data analysis as well as grounds for new findings in their wave propagation mechanism. These include known volcanic sites, active earthquake zones and beautiful waterfalls. Animals

such as elephants known to use infrasound signals in their communication over long-distance also abound on the

continent. Hence, strengthening the African capacity for infrasound monitoring through specific tailored training programs comes with enormous potential benefits in enriching the data analysis expertise of the various NDC staff. Thus, the need for Africans to be trained in this field.

The IAEA Safety Standards for decommissioning state that the regulatory body shall establish requirements for

decommissioning of nuclear facilities, including conditions on the end points of decommissioning. One of the main requirements is that the operating organization shall be responsible for all aspects of safety of the facility during its

lifetime, including decommissioning activities. It is also required that the operating organization is responsible for

decommissioning planning. It is never too early to start planning for decommissioning of a nuclear research reactor. The earlier the decommissioning planning is started, the better the decommissioning activities will be efficiently and

effectively carried out. This work mainly addresses requirements for decommissioning of nuclear research reactors. It is

intended to provide guidance to national authorities and operating organizations for the planning and safe management of decommissioning of nuclear research reactors.

Energy and climate

change

Over the last two centuries, industrial activities, deforestation and the burning of fossil fuels have released high

concentrations of heat-trapping agents called greenhouse gases (GHGs) into the atmosphere. While a certain amount of

greenhouse gas is important to keep our climate warm and liveable, these higher concentrations are warming the Earth’s surface to temperatures that threaten life on our planet. Carbon dioxide (CO2) and methane are two GHGs that have

increased dramatically due to human activity. As the world's need for energy grows, research focuses on developing

clean fuel initiatives to make the most of traditional fossil fuels while investing in cutting edge research to develop sustainable technologies which can be produced from diverse sources, including bio fuels, wind, nuclear and solar

energy. Developing energy efficient technologies for buildings, homes, transportation, power systems and industry is a

key component of reducing our reliance on fossil fuels. Energy technologies can have profound consequences for the environment both over the long term, as evidenced by the global climate change from fossil fuel carbon emissions, and

immediately, as was made vividly clear by the historic oil spill in the Gulf of Mexico. Sustainable energy technologies

will carry their own environmental impacts that must be understood before widespread implementation. Even the most

innovative and effective technologies cannot solve the world’s energy and climate problems without commensurate

changes in public policy. Understanding the potential social and economic impacts of sustainable energy technologies

will be critical to their success.

Navrongo senior high school. October, 2010-

march, 2011.

The objective of this research was to assess the black carbon concentration in air borne particulate matter in ambient air

due to the use of biomass for cooking in the Navrongo Senior High School. The Gent air sampler was used to sample airborne particulate matter in the Navrongo Senior High School. These particulates were collected on nuclepore

polycarbonate filters for a period of six months. In addition to determination of particulate mass in the two fractions by

gravimetric method, the aerosol filters were also analyzed for black carbon (BC) concentration levels using the black smoke reflectometer method. The average fine fraction mass concentration determined was 134.59µgm-3 (with a

minimum of 9.28µgm-3 and a maximum of 338.11µgm-3) and that of coarse fraction (CF) was 355.04µgm-3 (with a

minimum of 61.73µgm-3 and a maximum of 1117.43µgm-3). The black carbon concentration in fine, average was 7.62µgm-3 (with a minimum of 1.68µgm-3 and a maximum of 35.35µgm-3) and that of the coarse was 6.92µgm-3 (with a

minimum of 1.76µgm-3 and a maximum of 22.61µgm-3). The results of this research were compared to other works in

the country. It was however realized that the values of this research were about twice as much as the other works. This was due to the fact that biomass burning is generally used for cooking in the study area which is usual of Northern

Ghana and so produces a lot of black carbon as compared to the other area which are semi-urban areas in the southern

part of the country. The values obtained for coarse to fine particulate matter ratio suggest that, the particulates were not only largely made up of combustion generated carbonaceous particles but also particulate matter emissions from natural

activities.

An Empirical Correlation for Lateral Mass Flux due to Turbulence in Rod Bundle Supported by Spacer Grid with Split Mixing Vane Using STARCCM+ for Application in Sub-channel Analysis Codes

Enhancement of heat transfer for flow through rod bundles is linked to the extent and sustainability of mixing in the flow geometry. Spacer grids used as support for rod bundles in nuclear reactors, when attached with different designs of mixing vanes promote turbulent mixing by inducing swirl or forced lateral convection that improves mixing within or between sub-channels and thereby raising the margin of the onset of critical heat flux in light water reactors (LWR) and also ensuring a higher fuel cycle economy. To optimize design of mixing vanes and performance of spacer grids with mixing vanes, computational fluid dynamic simulations are carried out on new designs and validated experimentally prior to industrial application. In the present study, computational fluid dynamic simulation using STARCCM+ was performed for flow of water at a Reynolds number of RE1= 3.4×104 through a 5 X 5 rod bundle geometry for which the rod to rod pitch to diameter ratio was 1.33 and the wall to rod pitch to diameter ratio was 0.74. The two layer k-epsilon turbulence model with an all y+ automatic wall treatment function in STARCCM+ were adopted for an isothermal single phase flow through the geometry with imposed cyclic periodic interface boundary condition of fully developed flow type. The objective was to primarily investigate the extent of predictability of the physical problem by the computational fluid dynamic (CFD) code as a measure of reliability on the models employed. Develop an improved empirical correlation for predicting lateral mass flux due to turbulence. Validation of simulation results with experimental data showed good correlation of mean flow parameters with experimental data whiles turbulent fluctuations deviated largely from experimental trends. Generally, the agreement of simulation results with data obtained from the experimental investigation confirmed the suitability of the CFD code, STARCCM+ to analyze the physical problem considered. Relative to the non-linear standard k-epsilon and the k-Omega models, the two layer realizable k-epsilon turbulence model employed was unable to appreciably predict turbulent velocity fluctuations. The improved model developed for lateral mass flux due to turbulence showed dependence on one-fifth of the rod to rod pitch rather than on the gap width as present in other available correlations.

Estimation of pre-set

flux/ power using gamma dose rate

measured on top of the

reactor vessel

Most reactors incorporate out-of-core neutron detectors to monitor the reactor power. An accurate relationship between

the powers indicated by these detectors and actual core thermal power is required. This relationship is established by calibrating the thermal power. The most common method used in calibrating thermal power of low power reactors is

neutron activation technique. To enhance the principle of multiplicity and diversity of determining the in-core power and

average core temperature of low power research reactors, an alternative and complimentary method has been developed, in addition to the current methods. In this method, thermal neutron fluxes were correlated with measured gamma dose

rates. The empirical correlation equation obtained was used to predict neutron flux/power. The thermal neutron fluxes

predicted using measured gamma dose rates were in good agreement with values obtained using the activation

technique. At an indicated power of 30 kW, the gamma dose rate measured predicted thermal neutron flux of (1 ×

1012 ± 0.00255 × 1012) 𝑛/𝑐𝑚2𝑠 which corresponded to power of (30.06 0.075) kW. At an indicated power of 15

kW, the gamma dose rate measured predicted thermal neutron flux of (5.07 × 1011 ± 0.025 × 1011) 𝑛/𝑐𝑚2𝑠 which

corresponded to power of (15.21 0.075) kW. The power predicted by this work also compared well with power

obtained from a three-dimensional neutronic analysis for GHARR-1 core and power calculated using a correlation equation obtained from a full scale simulation heat transfer rig.

Design of fire fighting

robotics

This paper demonstrates the requirements specification design problems and solutions for the fire fighting Robot Project.

The robot must follow all rules and regulations of the programming. The coding is done in C++ object oriented program. The program was tested on a Dell Laptop.

The specific challenge of this project is to build a computer controlled Robot that can move through a model floor plan

structure of a house, find a lit candle and then extinguish it in the shortest possible time subject to a few operating factors. This must stimulate the real-world operation of a Robot performing a fire protection function in an actual home.

The candle represents fire, which has started in the home, which the Robot must first find and then extinguish.

Comparative study of

PIGE, PIXE and NAA analytical techniques for

the determination of

minor elements in iron slags recovered during

the excavation of an earthworks enclosure at

Asaman near Brakwa in

the Central Region of Ghana

In this work the capabilities of atomic and nuclear methods PIGE (Particle-Induced Gamma-ray Emission), PIXE (Particle-Induced X-ray Emission) and NAA (Neutron Activation Analysis) used for the determination of minor and trace constituents of iron slag have been compared in terms of sensitivities, advantages and limitations. The minor and trace elements identified in the iron slag samples were: S, P, Si, Al, Mn, C, Ti, Ni, Na, O by PIGE, Ca, Cr, Mn, Cu, Ni, Zn, As, Mo, Pb, Sb by PIXE and Mn, Al, V, As, Cu, Mo, Cr, Co, Na, , Zn, Ni, and Sb by NAA. By applying the three methods a very good overall picture of the elemental composition of iron slag material may be obtained.
