Executive Summary

A Joint Waste Management Plan (JWMP) is a proactive management plan for the next 5

years that has been developed by the SLC in conjunction with LLW Repository Ltd. Its

purpose is to demonstrate how the SLC is engaging with the National LLW Programme to

improve their implementation of and compliance with the UK Low Level Waste (LLW)

Strategy, through the delivery of the Programme Blueprint.

This JWMP provides an overview of the SLC’s current arrangements (section 1) for

managing their LLW arisings and identifies the transformational activities (section 2) that they

are undertaking, either independently or in collaboration with LLW Repository Ltd and other

organisations, to make a step change in their LLW management arrangements to deliver the

National Programme Blueprint future state. Section 3 provides an opportunity to identify

specific step change projects that are not within the current scope of work but which could be

undertaken either if funding became available or if internal or collaborative resource could be

identified to support the project. Appendix 1 contains the forecast of arisings by waste route

for the next five years and Appendix 2 provides a summary of the benefits identified as a

result of using the diversion routes.

This JWMP has been agreed by senior management as a commitment to the delivery of the

activities listed within. Key transformational activities will be tracked within the National

Programme governance arrangements to:

Assess performance;

Highlight success;

Deliver an integrated approach to dealing with the UK’s LLW.

It contains activities and waste forecasts for the 5 year period of 2019/20 to 2023/24.

Section 1 Magnox LLW Management Delivery Activities The Sites operated by Magnox in the UK that are covered by this Plan are shown in the map below:

Waste Management Organisation

On 1st of September 2019, Magnox became a subsidiary of the NDA. Magnox is structured

as a waste-informed decommissioning business, with waste and decommissioning

directorates responsible for delivering the waste-generating projects at all 12 sites. Project

waste management plans (PWMPs) are routinely used to define how waste from

decommissioning projects is generated and managed and waste management requirements

are considered at project gates using the company’s Waste Authority Review Process. Each

stage of the waste management lifecycle is overseen by suitably qualified and experienced

staff. Site waste operations teams are involved in moving, lifting and size reducing waste as

required, and segregating at source where practicable. A Magnox waste assurance

programme is in place to support waste compliance.



of 37


Magnox Approach to LLW Management

Magnox applies the waste hierarchy and BAT (BPM in Scotland) to determine the optimum

solution for the treatment and disposal of LLW arisings. Over the last nine and a half years

there has been a three to five fold decrease in the volume of waste consigned to the LLW

Repository despite a three to four-fold increase in total waste arisings from the

decommissioning programme. Magnox makes best use of the LLWR Waste Services

Contract to divert waste from the Repository for incineration sort and segregation, metal

treatment or landfill disposal and treatment of problematic wastes. Additionally, there are

surface decontamination systems at Winfrith and Hunterston A, which routinely process

suitable metals in order to release them directly from site for recycling. In the Period April

2019 to September 2019 Magnox has diverted approximately 72te of metallic LLW, 389m3 of

combustible LLW and 5580m3 of VLLW (LALLW) from the Repository (a diversion of 98%).

Magnox graphic showing LLW Management across 12 sites, with a clear step change in Repository

diversion since 2010. The current 5 year forecast has also been included.

Characterisation

Characterisation of waste is overseen by Magnox staff with the use of external support as

required. A significant driver for characterisation is to re-categorise waste from ILW to LLW,

LLW to LALLW/VLLW and from LALLW/VLLW to Out of Scope waste. Characterisation is

also key to the treatment of problematic or ILW/LLW borderline wastes, where identifying a

suitable treatment or disposal route is complex. A Characterisation Programme has been

established to specify and manage characterisation activities across Magnox, and a more



of 37


comprehensive Company Standard issued to standardise the approach to the

characterisation process across the 11 Magnox Sites (excluding Bradwell now in C&M). The

former radiochemical facility at Harwell requires to be characterised in preparation for

decommissioning. Planning for characterisation is being informed by the management of

wastes generated by trial decommissioning of two former laboratories within the facility.

Magnox is in dialogue with LLWR Ltd including the Supply chain to identify an optimised

approach to characterisation which supports safe and compliant decommissioning and

management of the resulting wastes.

Harwell Shielded facility currently undergoing decommissioning planning

Metals

Magnox is exploring various cost effective methods for decontamination of metals including

trialling the use of a Naturally Occurring Radioactive Material (NORM) Ultra High Pressure

Cleaning (UHP) UK permitted facility, for potential decontamination of metallic

decommissioned effluent pipelines. Currently such facilities are only linked to

decommissioning in the Oil and Gas Industry. The planned NORM facility decontamination

trial will be used on a few decommissioned Harwell Offsite Discharge Pipeline (ODP)

sections. If successful this trial could open a new route for SLCs with substantial cost

savings for recycling of pipeline sections.

Harwell ODP removal from in-situ and stored sections awaiting treatment at Harwell

Combustibles

Magnox continues to effectively use the Combustible Waste Treatment Service to reduce

LLW disposal volumes up to 100% by thermal treatment.



of 37


LALLW/VLLW

Magnox routinely uses the VLLW (LALLW) route for most sites. Magnox will be working on

opening this route for its last remaining site (Sizewell) over the term of this JWMP in line with

the generation of suitable waste arising’s. Harwell LETP decommissioning and land

remediation project (working closely with Augean & LLWR Ltd) has so far shipped over

15,000m3 of VLLW material to a permitted landfill site. This aids application of the waste

hierarchy as well as achieving value for money through the use of the various treatment and

disposal routes.

Problematic and Borderline waste

Magnox works closely with LLWR, other SLCs and key suppliers to develop waste routes

and contracts that offer value in the treatment of LLW. One such example was an innovative

treatment for higher activity oils unsuitable for direct incineration which involved acid washing

as a pre-treatment. Over the next five years Magnox will be developing routes for ILW/LLW

boundary and problematic wastes, e.g. FED (other than Bradwell’s) and other solid and wet

wastes, starting with Dungeness A borderline wet waste in 2019/20. This waste will be co-

disposed and conditioned with other wastes by Wood Nuclear at the Tradebe Inutec facility.

Back In 2015 Magnox initiated a joint project with LLWR and Tradebe Inutec (Winfrith) to

dispose Bradwell’s LLW Fuel Element Debris (FED) to the LLW Repository (note: FED is the

Magnesium alloy waste produced from removing some of the fuel cladding outer

components, not the fuel itself). To date 85% of the 1162 drums (out of a total 1367)

containing Bradwell FED have been supercompacted at Winfrith as a part of a multi-year

plan to process and consign to LLWR for disposal. The first shipment was successfully

consigned from Winfrith to LLWR for disposal in February 2017. Since then a further 10

containers have been consigned, with a further 4 ready for consignment from Winfrith,

representing approximately 50% of the inventory. Magnox is currently investigating the

disposability of similar FED from Sizewell A and Oldbury, in collaboration with LLWR Ltd

Waste Services. Winfrith TRS (Treated Rad waste Store) Drums containing encapsulated

sludge from past site reactor decommissioning which have been successfully re-categorised

from ILW to LLW, will be ‘direct emplaced’ in gaps around the edge of vault 8. In addition to

preserving space in vault 9 this first of a kind approach will reduce the amount of infill



of 37


imported by LLWR, avoid the need for 400te of steel containers and avoid 1,250m3 grout at

the repository.

Low Level Waste Disposal

Where waste disposal to the Repository is selected as the preferred option, supercompaction

and co-disposal is applied to maximise the packing efficiency and hence preserve repository

capacity.

Transport

Magnox use road to rail transport regularly and Harwell waste transfers to Sellafield continue

using rail for many different types of nuclear materials. Winfrith site is also planning to

consign TRS (Treated Radwaste Store) drums to LLWR via rail for direct emplacement in the

near future.

Business and Information Reporting of LLW

In addition to this JWMP, Magnox maintains scheduling and tracking systems that include

the NDA Mission Reporting for all 11 of its sites (excluding Bradwell in C&M), which forecast

LLW volumes and consignments over a financial year. Tracking systems are updated on a

monthly basis. All LLW forecasts are underpinned by information mainly from Project Waste

Management Plans (PWMPs); this work also includes re-categorisation of ILW to LLW

volumes, where appropriate. Magnox uses a live inventory system that is updated regularly.

This system is also being used as the platform for characterisation information.

Magnox supports the National Waste Programme through active participation in the non-

routine and cross-estate collaborative initiatives; regular provision of information and

progress updates; and attendance at scheduled monthly and quarterly meetings.

A proportion of the graphite and potentially all of it (refinement of the graphite activity assessment is underway) could be sent to LLWR, but the graphite is precluded from disposal down this route due to high activity charges (specifically C-14) compared with GDF. Current BAT is to dispose to GDF.

Removal of the artificially high cost of high

activity LLW c/w disposal as ILW and better

alignment with waste hierarchy. Minimisation

of ILW generated by the segmentation of the

Dragon reactor core. This could also allow a

larger amount of segmentation work to be

carried out prior to the availability of the ILW

waste route. A reduction of long term ILW

storage costs

Appendix 1 – Five Year Forecast Magnox Year Forecast ‘Roll up only’ Assumptions

1. The following waste forecasts are based on Inventory and site Lifetime Plans (LTPs), underpinned where applicable by Project Waste Management Plans 2. Some waste projects contributing to the forecasts are currently at pre-Gate 3 and therefore subject to sanction and validation and release of funding 3. The Magnox Baseline is managed through the Magnox Portfolio Management process with any required changes progressed via Baseline Change

Proposals (BCPs). As the Magnox Baseline takes precedence any resulting impact on the JWMP will be reflected through NWP Change Control

Saving from diversion based on difference between cost of disposal to LLWR and cost of diversion/treatment.

Transport costs - assume £600/HHISO for disposal to repository and for VLLW and combustible diversion.

Assume £3700/HHISO for metallic diversion (this assumes 50% treated abroad at £6800/HHISO and 50% in UK at £600/HHISO).

Assume 4 empty HHISO/journey and 2 full HHISO/journey; except for metallic for disposal, where 1 full HHISO/journey to repository is assumed and full

height ISO where 1 full height/journey is assumed.

Treatment cost for metallic = £cost norm*te waste + container costs*number of containers needed(assume can use twice to send material for treatment) +

transport cost for empty and full HHISOs + cost of secondary waste disposal (5% of original volume/10(to give number of HHISO)*disposal volumetric

cost*19.5 (HHISO volume)).

Assumption - 10te (metal) or 10m3 (combustible/VLLW) waste per HHISO for disposal.

Assumptions

Assumption - 1te metal = 1m3 (EGG01) for the purposes of summing total quantity of waste.

Assumption that VLLW waste would not have been compacted if it had been sent for disposal.

Year 2018/19 - Disposal cost for VLLW = waste volume/10(to give number HHISOs)*disposal price from LLWR Price List (£3161*RPI)*19.5 (HHISO volume)

+ (£8.2k HHISO cost + £1.2k activity charge)*number HHISOs + transport cost for empty and full HHISOs. From LLWR Service Price List Effective 01/04/16

Repository capacity preserved is based on 0.00024 years / HHISO.

This is based on a capacity gap of 85years and 352184 HHISO. Gap calculated comparing 2010 UKRWI (excluding CLESA and DSRL) with LLWR LTP13 target

waste inventory profile (up to vault 18).

Volumetric disposal cost for LLW disposal has been increased annually by 3.5% as an estimate of inflation in line with RPI.

Year 2018/19 - Disposal cost for metallic = waste volume/10(to give number HHISOs)*volumetric cost from LLWR Price List(£3161*RPI)*19.5 (HHISO

volume) +(£8.2k HHISO cost + £12k activity charge)*number HHISOs. Transport cost assumed to £600 for full and empty container. Data from LLWR

Service Price List Effective 01/04/16.

Year 2018/19 - Disposal cost for combustible waste = (disposal cost per drum (20% x disposal cost per m3 *RPI) + activity charge/drum (£200))*number

of drums (assume 0.2 m3 waste/drum) + drum cost(£36/drum) + transport cost (@72 drums/fullheight ISO). From EGG01 Rev2 and LLWR Service Price

List Effective 01/04/16.

Treatment cost for VLLW = £cost norm for VLLW*volume of waste + soft sided bag cost (1m3/bag @ £250/bag) + transport cost (assume 15m3/journey)

Treatment cost for combustible waste = £cost norm for combustible waste*volume of waste + drum cost (assume 0.2 m3 waste/drum*£45/drum) +

transport cost (@72 drums/fullheight ISO)
