Lifetime Plan PSWBS Site ref.: 212006/07 Lifetime Plan Revision B April 2006

Lifetime Plan OverviewThis Lifetime Plan describes the totality of the activities in terms of scope, schedule and cost to be undertaken at Berkeley by British Nuclear Group on behalf of the NDA. It covers the whole site lifecycle from present through to the complete discharge of the site’s liabilities over 78 years.

Berkeley is well advanced into decommissioning with much work successfully completed by British Nuclear Group. The three remaining phases are the completion of Care & Maintenance Preparations (C&M Preps), Care & Maintenance (C&M) itself, and Final Site Clearance (FSC). This Lifetime Plan (LTP) describes the activities to be undertaken within these phases between April 2006 and December 2083. It incorporates a Near Term Work Plan (NTWP) which addresses in detail the planned work between April 2006 and March 2009 and the Lifecycle Baseline (LCBL) which addresses all work during the sites lifetime in slightly less detail. A wealth of information from existing plans developed over a number of years has been drawn on, addressing the optimum methods to progress work up to the final site clearance of Berkeley. The format and presentation of the LTP is in accordance with Nuclear Decommissioning Authority (NDA) PCP 07 and consists of five main parts as illustrated in figure 21.001.

British Nuclear Group and its predecessor companies have safely and securely carried out nuclear research operations, power generation and decommissioning at Berkeley for over 40 years. Berkeley has played a major role in the UK civil nuclear industry.

Figure 21.004 shows the major current and near future activities for this site and how they relate to the NDA led National Prioritisation Working Group priority areas.

Priority area 1, Non-discretionary work is that necessary to maintain legal compliance and prescribed and agreed levels of safety and security.

Priority area 2, Operations activities are based on electricity generation commitments. These are not applicable to Berkeley as it is defuelled and decommissioned.

Priority area 3, Discretionary work is that which will allow achievement and acceleration of decommissioning and all other work.

Current site focus/priority indicates the priority that each focus area will have when funds are being allocated.

Berkeley Lifecycle Baseline Key Phases

Over the past 40 years, Berkeley

has been at the forefront of the

UK civil nuclear industry, and

is planned to be the first UK

Magnox site to enter C&M. The

site comprises a nuclear power

station, headquarters offices and

nuclear laboratories; Berkeley is

a complex site where innovative

solutions to decommission and

cleanup the site are required.

2006

Care & Maintenance Preparations 1992–Dec 2013The C&M Preps phase prepares the site for a period of quiescent storage, during which only the two reactor buildings will remain. This work is already well under way at Berkeley. The principal activities are the retrieval and processing of radiological waste from the Active Waste Vaults and the decommissioning of the Caesium Removal Plant. In parallel with these, another major project, the Shielded Area Facility, will be decontaminated and demolished along with all other buildings remaining on the licensed site. On completion of these activities all remaining radiological waste on site will be passively stored.

Partial Site Delicensing Dec 2006Berkeley has a wealth of office accommodation, having been a Magnox headquarters. To separate the need for demolition of these conventional buildings from the entry requirements for C&M, part of the site will be cleared of radiological hazards and delicensed, thus reducing regulatory restrictions on clearance or reuse. Although the baseline strategy is complete site cleareance, delicensing will provide an opportunity to build on the work and recommendations of the Berkeley Task Force for alternative future use of the site. The Site Stakeholder Group (SSG) are now reviewing the site end state and the potential options for the future use of site.

Work in life cycle baseline has been scoped to ensure the safe, secure and cost effective discharge of the liabilities. Innovative ideas, based on Berkeley’s unrivalled experience are being used to augment the current baseline decommisssioning strategies.



Care & Maintenance (C&M) Dec 2013–Mar 2074Throughout the C&M period, the site will remain in a quiescent state with no works undertaken to dismantle any of the remaining structures. Monitoring and maintenance of the reactor buildings and site will constitute the primary activities on site, including any works necessary to ensure the integrity of the external weather envelope of the buildings. The other major activity within this period will see the passively packaged waste stored on the site removed and transported to the UK ILW National Repository

Final Site Clearance (FSC) Apr 2074–Dec 2083FSC will see the site cleared of all remaining hazards and the removal of the final buildings, services and facilities. A phased approach across all Magnox reactor sites has been adopted for this phase of work to enable knowledge gained to be implemented on other sites. All waste will be managed through a purpose built facility on site. All radiological waste will be removed to the UK ILW and LLW National Repositories. Non-hazardous waste from building demolition will be recycled where possible for reuse on site. The site will be resurveyed to allow the Site Licence to be withdrawn and the land released for alternative use.

Throughout the LTP Berkeley will

remain committed to ensuring

work is carried out safely.

FSC

C&M Preps

C&M

At Berkeley, British Nuclear Group’s mission is to safely, securely

and cost effectively deliver the site into C&M and onwards to FSC

whilst maximising value for money through innovation and the

uncompromising application of simple, disciplined project delivery.

Success is built on British Nuclear Group’s ability to engage and

work in partnership with regulators, stakeholders and industry

experts in the development and delivery of challenging and

innovative decommissioning plans for the site.



Works within the C&M Preps phase are well underway with many major facilities already decommissioned and demolished.

The remaining works within this period are focused on:

• Safe and environmentally friendly delivery of the work and compliance with the conditions of the nuclear site licence. • Reduction in radiological hazards through the retrieval, processing and packaging of legacy wastes. • The decommissioning and demolition of all redundant facilities, buildings and services. • Safe and passive storage of all packaged wastes. • Management of the site through transition into a period of quiescent C&M.

Transition 21.10Restructuring of the workforce and organisational change needs to be managed effectively as Berkeley moves towards

C&M, building a team with the ability to take on the challenges and provide value for money to the NDA, as well as looking at the needs of staff and the local community and stakeholders. The majority of the category’s cost is severance payments.

New Construction 21.11The Active Waste Vault Retrieval (AWVR) project forms the critical path through the site decommissioning programme to C&M. Facilities must be built to enable the retrieval and processing of the waste in the vaults.

Also included in this category is the provision of the site ILW store. This is currently under going a major strategy review, the outcome of which will be change controlled into the baseline plan.

Decommissioning & Termination 21.13The principal projects within this category are the decommissioning and demolition of the Shielded Area Facility, the AWVR and the CRP, and Partial Site Delicensing. Works to

decommission, deplant and demolish other facilities on the site include the removal of the Active Effluent Treatment Plant (AETP), preparatory works associated with the reactor buildings and the demolition of all other buildings bar the ILW store. Final characterisation and contamination surveys will be undertaken, and relevant remedial works completed, before the site enters C&M.

Waste & Nuclear Materials Management 21.14This category deals with ILW, LLW, hazardous waste and non hazardous waste. The majority of work is the retrieval, processing and packaging of legacy wastes for on site storage. There are two main projects, the AWVR and the Caesium Removal Plant (CRP) for which the operations phase falls into this category.

Non-hazardous waste will be recycled and reused on the site whenever possible, reducing transportation costs and the impact the movement of such vehicles have on the

Site Support 21.15Decommissioning operations and maintenance, and health physics, are essential to the efficient running of the decommissioning projects, ensuring availability of equipment, and that all relevant health physics and environmental services (Personal Protective Equipment (PPE), dosimetry, laundry and radiological surveys) are provided when required by the projects. Supply Chain Management will enable the challenges of the decommissioning timetable to be met through the development of excellent working relationships within the supply chain. Programme management will lead on the management of the decommissioning projects and the identification of potential opportunities to accelerate the site towards C&M.

Support Services 21.16Compliance with the Nuclear Site Licence and discharge authorisations granted under the Radioactive Substances Act is fundamental to the operation of the site and to the relationship the site has with the regulatory bodies. Along with safety, this is a

top priority for the site. Berkeley has attained ISRS level 7 demonstrating its overall robust quality of safety processes. Maintenance of ISO 14000 accreditation is also important in showing the site’s commitment to minimising its impact upon the environment.

Stakeholder Support 21.17There is going to be a great deal of activity at Berkeley over the coming years and the maintenance of communication with all regulators and stakeholders is important and essential to the timely completion and delivery of the decommissioning programme.

Revenue Income 21.20

Revenue Income will be raised through services to British Energy (BE), tenancy arrangements and the sale of recycled scrap metal.

Berkeley site has been organised as an integrated project team with many functional areas such as procurement, project controls and EHS&Q embedded within the major projects. This drives better and clearer accountability and facilitates the more effective discharge of the site works. To facilitate this, additional expert resource is being recruited in these areas.

Partial Site Delicensing 2006Berkeley Nuclear Licensed Site is unique in that it incorporates the Berkeley Power Station, laboratories

with a shielded area facility, and conventional office accommodation within the nuclear site boundary.

An innovative decommissioning strategy will facilitate delicensing of a major part of the site enabling

early clearance of the facilities or provision of opportunities for socio-economic redevelopment with the

community.

Delicensed Site

Licensed Site

Partial Site

Delicensing

The Berkeley site comprises a decommissioning nuclear power station, laboratories with a shielded area facility and conventional office accommodation. Currently the entire site is licensed by the Nuclear Installations Inspectorate (NII). This necessitates that the various conditions of the licence be applied to the entire site, regardless of the work that has to be undertaken.

It is also a condition of entry into the C&M phase that all buildings within the licensed site other than the reactor buildings and the waste store are demolished. However, many buildings are office complexes, a legacy from the site having been the headquarters of Magnox, and as such many have no history of radiological use. Some of these buildings are currently leased to companies associated with the nuclear industry.

Through this initial phase of the baseline, the strategy is to achieve agreement from the regulators for the redrawing of the site licensed boundary, thus releasing a large part of the site from nuclear regulatory

requirements, facilitating both demolition or alternative use.

In order to effect partial site delicensing a number of activities are necessary to satisfy the regulators that the area of the site is suitable for removal from the nuclear site licence.

A contaminated land study must be completed and agreed by the regulators. This involves compiling a full operational history of the site with detailed descriptions of all activities, radiological history and past events, to support and demonstrate that ‘no danger to the public’ exists. A programme of surveys is currently being conducted to provide the evidence necessary to show that no hazard from previous activity will impact any future planned activities on the site.

Works to facilitate the partial delicensing and separation of the sites is underway. This provides an opportunity to accelerate the decommissioning programme for those buildings on the area of the site to be

delicensed that have been used previously for radiological purposes. This will reduce the overall cost of decommissioning the site. This also provides options for the SSG to decide on the site potental uses.

A new security fence is being erected along the proposed new licensed site boundary and this will provide a secure perimeter for the licensed part of the site.

The onward strategy for the management of the delicensed site is being developed by the Berkeley site facilities management group in conjunction with the NDA, and will take into consideration the residual responsibilities of the delicensed area of site including the installation of an independent fire detection system and maintenance of the River Severn navigation landmark.

The decommissioning and transition of the site into a period of quiescent C&M is a time of great change for both the site and the local community. It is important that British Nuclear Group honours its commitment and obligation to give encouragement and

support to activities that benefit the social and economic life of the community in which the site is located.

The Berkeley Taskforce was formed in 2004 to consult with all interested stakeholders and investigate all options and opinions to ensure the most advantageous recommendations for the future of the site were established. The SSG have now taken over the role of identiying the site end state and future uses. The SSG will use the work of the taskforce in conjuction with other work to form its views.

Although the current planned future for the delicensed site is for it to be demolished, the partial delicensing of the site, together with the production of a robust business case are prerequisites for the implementation of the recommendations of the Berkeley Task Force.

Cost for Partial Site Delicensing falls within the Decommissioning and Termination Category.

Figure 21.012 - Care and Maintenance Scope of Work

During the quiescent C&M period between 2014 and 2074 the staffing on site will be reduced to a level appropriate to maintain safety and security.

Throughout this phase no dismantling work will be undertaken, the primary activities being monitoring and maintenance of the reactor buildings and site.

This will include the recladding of the reactor building.

Waste stored on site will be removed and transported to the UK ILW National Repository between 2046 and 2049.

The recladding of the reactor buildings and emptying of the ILW store are expected to require an increase in work such as the production of safety cases, and securing consents and authorisations. These costs have been spread across the phase. There will also be a need to engage with stakeholders to ensure they are involved and consulted in plans for the site. These costs have been time phased.

All buildings will be routinely maintained and regularly inspected, undergoing periodic surveys conducted by suitably qualified and experienced civil and structural engineers. The buildings will be inspected on a periodic basis, or following severe weather, to ensure the integrity of the buildings’ weather envelope.

The programme for the inspection and maintenance of the site is derived from the site safety case and maintenance schedule. The following indicative programme is considered representative, based on current knowledge and includes elements of land management around the reactor buildings:

Regular external inspections to identify any obvious damage to the fabric of the building (such as the loss of cladding) and ground maintenance of the site as required.

Half yearly external engineering inspections and minor maintenance of:

• The building fabric. • Hard standings, access road and boundary fence.

• Ditches, manholes and out-falls. • External drainage sumps.

Yearly internal engineering inspections and minor maintenance of:

• Primary access routes. • Inside face of building fabric. • Primary building and plant structures. • Basement areas especially where there is a potential for ground water ingress.

External and internal engineering inspections at 25 year intervals, followed by more major maintenance, if required, including:

• Full structural inspection of primary internal access routes, with the repair or replacement of any unsafe structures. • Minor re-pointing of brickwork, etc as required. • Side and roof cladding repair – attention would be given to any leaking joints or damaged sheeting. • Examination and sampling of primary

steel structures to ascertain the potential for serious corrosion. • Examination and sampling of primary concrete structures to ascertain any sign of cracking, spalling or rusting of reinforcement. • Repair or replacement as necessary of paved hard standings, drainage ditches, manholes, drains lines, out falls and security fencing.

Relevant components of structural surveys will also be repeated after periods of severe weather or seismic activity.

To maintain a weatherproof structure it is anticipated that there may be a need to replace the external cladding of the buildings during this period. For financial planning purposes it is assumed that the cladding on the buildings will be replaced 28 years into the C&M period.

Radioactivity levels will be monitored to demonstrate adequate contamination control, and thus verify the effectiveness of containment and demonstrate compliance with authorised discharge limits.

On site radiological information will be obtained during the reactor building internal inspection visits through appropriate sampling and surveys.

In addition to the on site monitoring, a limited off site monitoring programme will be performed. Annual sampling and assay of green vegetation gathered from the locality should be sufficient to indicate any changes to the ambient levels of radioactivity in the surrounding environment, thus providing assurances to the local community.

Work will take place in the last four years of C&M to prepare for FSC. That work is described as taking place during FSC although it is costed and scheduled within C&M.

Between 2046 and 2049 the site’s ILW Store will be emptied and the ILW transported to the UK ILW National Repository

Reactor buildings will be maintained throughout the period to ensure their integrity.



Final Site ClearanceOn completion of the FSC phase, the site will be cleared of all remaining buildings, including the reactors. Following a ground survey, remediation and landscaping the site will be released from its licence and made available for reuse.

The current strategy for FSC is to undertake the works in a sequenced programme across all Magnox reactor sites so as to gain maximum benefit from the transfer of knowledge and experience from site to site. Berkeley is currently scheduled to be the first site to enter this phase of decommissioning, the date for the start of the works being 2074.

Preparatory work for this phase will take place in the last four years of C&M. A small team will be assembled in FY 2070 to review the existing plans with a view to commencement of recruitment prior to the three year preparatory period.

Once key staff are in place they will continue the recruitment and skills development process over the next three years. Over these years work will involve planning the necessary new construction, decommissioning activities, and the functional support they will require.

The FSC phase will commence with the reinstatement of the site infrastructure

including new security fencing and access control points, the provision of services for decommissioning, office, welfare accommodation and workshop facilities.

A Waste Management Facility (WMF) will be designed, constructed and commissioned at the start of the phase, and used to process all waste arising from decommissioning work. Wastes will be transferred in a controlled manner from the workface to the WMF where they will be monitored and characterised. Active waste will be packaged for off site transport and disposal. Clean waste will be recycled for backfilling on the site whenever possible.

Access to the reactor building structure will be gained at an early stage in the programme for preliminary structural and radiological surveys to be undertaken followed by initial cleanup of any loose contamination identified.

A section of the reactor building roof will be removed to allow large items of plant to be lifted out using a mobile 150 tonne capacity

crane situated at ground level. A 50 tonne capacity mobile crane will be lifted in through the same roof opening to assist in dismantling operations. Pile cap extensions will be constructed over the pile caps and a temporary, removable cover will be placed over the roof opening in order to maintain a weather tight envelope throughout the dismantling of the reactor block.

Each reactor will be completely removed by dismantling the pressure vessel and supporting diagrid, removing other active concrete and steel, dismantling the reactor structures and removing all inactive concrete and steel.

Once all active plant and contamination has been removed from the reactor buildings they will be demolished and voids below ground level back filled.

Depending on the function of the buildings being removed, some minor decontamination may be needed before the strip out of fittings and demolition can commence. Demolition will be carried out

using conventional industrial techniques.

As demolition of site buildings and facilities nears completion, final clearance of the site will commence. This work will see the removal of:

• Site infrastructure (roads, car park, hardstandings, inner fences, underground main cables and water mains). • Previously active drains and outfalls. • Foul and surface water drains if they are less than 1 metre below ground level.

Monitoring activities during C&M will have identified and controlled any areas of soil contamination on the site. Any contaminated soil will be excavated and processed for disposal through the WMF.

At the end of the FSC phase, all the new services and structures installed to support the project will be deplanted, demolished and removed. All buildings will be removed down to a depth of 1 metre below ground level and any remaining structures punctured to assist drainage.

Following the clearance of all structures from site a radiological survey will be carried out to demonstrate that ‘no danger to the public’ exists.

Once this has been confirmed, the entire site within the outer fence will be re-graded and covered with 300mm of imported topsoil. Land drains will be installed across the site and the whole area seeded.

On completion of this work the site will be in a condition to allow the Site License to be withdrawn and the land to be made available for alternative use. The final fencing will then be removed.

At this point the lifecycle of the site will be complete.

NTWP (Years 1 to 3)

Whilst the C&M Preps phase of a nuclear site’s lifecycle is a period of great transformation, these NTWP years involve a particularly large number of very fundamental changes. The results of a wide variety of strategy reviews will impact during the next three years.

During the first year Berkeley will have completed its move to integrated project teams. The major projects in particular have team members that belong to functional areas such as procurement and project controls, where traditionally these people had sat in separate departments. The embedding of this kind of support in the heart of the team will help the delivery of the work to be more effective and efficient as those providing the functional services will be privy to a greater insight into the project and will be on hand to proffer advice and opinion unsolicited. All projects in the C&M Preps phase of this Lifetime Plan have been costed in this manner.

There are also major changes associated with the delivery of the four major projects.

The AWVR project has undergone a full review and strategy change during the year prior to this NTWP. The primary works are the close out of design and engineering activities. Initially this will involve the development of the waste retrieval arm and major plant items, plans for the civil construction of the building and installation. During the last year of this NTWP the building will be constructed and inactive plant will be tested. The AWVR project currently also includes the modification of the ILW store. The strategy for onsite storage of ILW is currently being reviewed and it is intended that a major strategy change will be enacted and be brought into the baseline early in the first year of this NTWP.

The CRP project involves the Post Operational Clean Out (POCO) and deplanting of the equipment in the facility. Engineering work will develop ILW and LLW solidification solutions. Major plant items will be procured. ILW and LLW will be retrieved and processed. The processed ILW will be transferred to a site buffer store when

constructed.

Work in the Shielded Area Facility includes the clean out and demolition of the cells and caves. Critical to the success of this is the transfer of the ILW currently in caves one to three to a new ILW buffer store during the second year of this NTWP. This is key to the completion of the NTWP scope of work for decommissioning.

Partial Site Delicensing is planned to happen during the first year of this NTWP, effectively redrawing the boundary of the licensed site. To facilitate this contaminated land surveys are ongoing, a safety case will be produced and site access modified. Subsequently the majority of people working at Berkeley will no longer be working on a licensed site and the delicensing of part of the site will then facilitate the demolition of the conventional buildings as they will be free of the constraints inherent of a licensed site.

During this NTWP decisions will be made for the future of the site. The SSG will work with the NDA and British Nuclear Group to

The work in the NTWP is primarily centred around four major projects; AWVR project, CRP, Shielded Area Facility and Partial Site Delicensing. The progression of these projects will be a major step towards reducing the Nuclear Liability and hazard on site and moving the site significantly toward C&M.

identify the site end state and the feasibility of future uses, building on the work of the Berkeley Task Force. The current plan for all the sites is a cleared site, with demolition scheduled to start during the last year of the NTWP. Whatever the outcome, the site will see major change, whether it be a change of use, or the removal of most of the buildings

Berkeley currently has many tenants, companies servicing the nuclear industry, which are currently planned to have left site by the final year of the NTWP. Their future on the site will be negotiated. It is intended that BIL will remain on site, but their arrangements with the NDA and British Nuclear Group will change and they will become a Registered Premises in their own right.

Also, as Berkeley has been home to the Reactor Sites central functions, the implementation of the British Nuclear Group’s Reactor Sites Organisational Change Programme will have a dramatic effect on their presence on site. The intention is the development of independently licensable and capable sites with the reliance on centralised functions for technical and business support minimised. This means the work, and therefore staff will be transferred from Berkeley to sites around the country.

The allocation of work and staff to bundles has meant that control, leadership, oversight and direction of the existing and the new

shadow Site Licence Companies is divided into NTWP DVs and included in appointed sites’ NTWPS. Whilst other sites have the shadow SLC governance DVs, Berkeley has absorbed the Magnox Electric Governance & Change DV which includes all the residual scope of work, ensuring the ongoing governance of Magnox Electric Ltd and facilitating the transfer of governance, staff, contracts and IT systems to the shadow bundle SLCs.

The operations phase within the nuclear laboratories only ceased in 2005. Therefore Berkeley will be undertaking a major review of its operational procedures to ensure they are fit for purpose and effective for a wholly decommissioning site. This will include reviews of:-

• Berkeley’s emergency scheme given that the site has very low level of hazard remaining on site. • Working arrangements to make them more flexible, this will include a review of the shift structure and operations requirements. • Permit to work system to consolidate procedures. • Existing safety rules; which are based on operational plants, to make them more effective and safe for the constantly changing nature of a decommissioning site.

All these reviews and changes will ensure the safety of people on site and the public,

and will be carried out in partnership with the trade unions and stakeholders. They will draw on worldwide best practice at decommissioning sites.

Berkeley is undertaking a major review of

its operating procedures to complete the

change from a partially operating to a wholly

decomissioning site, employing world class, fit

for purpose decomissioning procedures and

systems of work.

Key

The design of the retrieval and remote handling equipment required by the AWVR project is a key enabler for the retrieval of waste from the vaults.

Major Assumptions & ExclusionsAssumptions are made to move from a position where uncertainty exists to one that provides a firm basis for the work, allowing it to be fully scoped, scheduled and costs to be estimated.

Figure 21.021 - Major Assumptions and Exclusions

Figure 21.021 contains the key assumptions that bound the scope of work on the Berkeley site. Should the assumptions prove invalid the scope, schedule and cost of the work may change.

Throughout the lifecycle Berkeley will need to work within constraints imposed by outside influences that are not in the control of British Nuclear Group. The major assumptions are principally those associated with critical path projects and legislative compliance.

This baseline is structured on the current strategy to defer FSC until 85 years after the cessation of generation, thus allowing radiation levels to decay. Implementation of the NDA strategy for acceleration of decommissioning of Magnox stations would mean increased requirements for remote handling equipment to facilitate the removal of the reactors which would impact on the level of services and support required.

The basis of the plan can be affected by changes in the requirements of regulators or government that may result in changes

to the existing strategies or regulatory framework.

Changes to the current practices and technology employed may result in the schedule of cost being varied. The waste strategy defines disposal routes for the site’s waste inventory and it is assumed that these will remain available to Berkeley throughout the lifecycle.

PSWBS Assumption Justification Applies to:

PSWBS Exclusions Justification



Risk ManagementIt is important that cost and programme risks associated with the delivery of the work are well understood to enable effective risk mitigation activities to be implemented. This section explains the more significant risks and how they will be managed to the satisfaction of the NDA.

Figure 21-22 contains the key risks associated with this category. The development and utilisation of rigorous risk mitigation plans are a constant and valued part of process, ensuring ability to manage all risks effectively.

Availability of top class people is critical to the success of Berkeley, there is currently a significant amount of high profile construction work in the UK and as such the recruitment and retention of key staff is Berkeley’s major risk.

Site strategy relies on the use of an ILW store. Unless the safety case is approved it will not be possible to store the ILW in the planned store during C&M. Following an ongoing review it is now likely that a change in strategy will be change controlled into the baseline plan and implemented during the first year of the NTWP.

The design of the FSC Waste Management Facility and scheduled throughput of waste is based upon predicted waste volumes and estimates of their activity levels. These will be regularly reviewed to ensure that

the processing, packaging and throughput requirements are correctly identified and incorporated into the schedule and design of the facilities.

Figure 21.022 - Risk Summary

Risks Applies to:

LCBL NTWPSupport Services, Personnel

Description Availability of resources when required and retention of resources for the necessary period are at risk due to the strong labour market in project based skills and the nature of the employment contracts on site.

✓ ✓Possible Impact Not having the resources available when required will affect the ability of the site to liquidate its work in line with the

schedule and may incur additional costs.

Mitigation Activities Early identification of the requisite skills and appropriation of these skills. Use of longer term agency and staff contracts with the development of staff to backfill agency help aids retention

Contingency Owner Site

New Construction, ILW Store

Description Availability of an on-site ILW store when required is critical to allow continued decommissioning of the CRP and Shielded Area Facility and the operations of the AWVR. The current store design may not be able to make a safety case.

✓Possible Impact Major impact on the costs for the site and the schedule due to the requirement for an alternative storage solution.

Mitigation Activities This risk is not directly mitigated. Work to identify options is underway.


Waste & Nuclear Materials Management, FSC ILW Operations

Description Waste volume and activity levels for the wastes to be processed in FSC are different to those predicted by the analysis and estimates

✓Possible Impact Potential significant change to the baseline costs, schedules and methodologies

Mitigation Activities Regular review and update of the waste types and volumes and refresh of estimates as appropriate


Decommissioning & Termination, Reactor Dismantling

Description Reactor radiation levels do not decay as quickly as planned for FSC

✓Possible Impact Higher radiation levels could require remote operations decommissioning or lead to higher worker dose.

Mitigation Activities Regular review and surveys of the reactor radiation levels and predictions re-baselined. Depending on results, alternative solutions will be explored.


Transition

Description Potential sale of British Nuclear Group

✓Possible Impact Causes increased cost and schedule, and distraction

Mitigation Activities Keep staff informed to minimise uncertainty


Support Services, Personnel

Description OPPORTUNITY - Flexible working hours

Reconciliation of Costs

The figure for the LCBL was calculated by deducting the amount allocated for FY05/06 from the LCBL cost and then escalating the balance by 3.1%, as instructed by the NDA.

A major reason for the overall increase in cost has been the comprehensive review of strategy and approach to the AWVR project. All phases of this project have been extended. As this project is on the critical path for C&M, the entry date has inevitably moved. This has caused a review of infrastructure necessary to support decommissioning over a greater length of time.

Another key cause is a fundamental strategy review for the site. There has been a move to integrated project teams, and a significant increase in skills in project management and project controls.

In addition to this the Reactor Sites costs for Magnox Electric Governance and Change, resultant from bundling of site costs, costing approximately £164.7M, have been allocated to Berkeley.

Transition 21.10

Severance costs for C&M Preps have been reviewed and increased to accommodate the expected workforce at the end of the C&M Preps phase. New work to start the preparations for FSC has also been included

New Construction 21.11The AWVR project involves construction that has been moved to this category from Decommissioning & Termination.

Decommissioning & Termination 21.13AWVR project construction work and waste processing for both the AWVR and CRP has been moved to the relevant categories. Some work has been deemed unnecessary and has been removed from the LTP

Waste & Nuclear Materials Management 21.14The AWVR and CRP projects involve waste processing which has been moved to this category from Decommissioning & Termination. The management of hazardous waste has also been moved to this category

from Support Services

Site Support 21.15Various elements of work in this category previously costed to projects in Decommissioning & Termination have been reallocated following restructuring, resulting in higher category costs.

Support Services 21.16The Reactor Sites costs for Magnox Electric governance and change are in Support Services. As in the Site Support category, restructuring has also meant the reallocation of costs previously costed to projects in Decommissioning & Termination

Stakeholder Support 21.17Stakeholder support activities during C&M and FSC have been reviewed and increased commensurate with modern expectations of stakeholder engagement and involvement.

Revenue Income 21.20Whilst income from tenancy services rises, BE’s contribution to the storage and processing of their ILW is considerably less than in the LCBL.

As Berkeley approaches C&M the requirement for staff will decline as decommissioning activities are completed.

During C&M resource will generally be required to support the inspection, monitoring and maintenance of site. The peak during this period is the resource necessary to re-clad the reactor buildings to ensure a weather proof envelope in 2040. The resource required to empty the Intermediate Level Waste (ILW) store between 2046 and 2049 is negligible.

FSC requires a massive ramp up in resource, predominantly through subcontract, responding to the increased amount of activity planned during that phase. The peak occurs when the reactor dismantling facilities are still being installed, but have already facilitated the commencement of reactor dismantling and the processing of waste. The subsequent drops in numbers are commensurate with the completion of all new construction, the dismantling of the reactor, and finally the demolition of the reactor building and

completion of all waste processing. Figure 21.033 - NTWP Staffing Profileagainst Time

Figure 21.034Shows the retrieval, processing and disposal of all ILW on site across the lifecycle. ILW that is not integral to the reactors will be retrieved and packaged during C&M Preps and stored until 2046 when removal to the UK ILW National Repository will commence. All ILW retrieved during FSC will be assigned to that repoisitory when packaged, with there being no significant period of on site storage.

Figure 21.035Shows the amount of LLW arising across the Lifetime Plan.

Figure 21.036Shows the demolition across time of the cumulative internal volumes of the buildings on site. The majority of buildings will be demolished during the C&M Preps phase leaving only the reactor buildings until FSC.

Figure 21.037Shows the breakdown of Non-hazardous arising from the demolition of buildings during C/&M Preps..

ConclusionThis Lifetime Plan demonstrates continued effective decommissioning and clean-up with robust and challenging plans to take Berkeley through to Final Site Clearance. It seeks to maximise value for money by developing innovative solutions to the acceleration of the clearing of Berkeley site.

The decommissioning and clean-up of Berkeley represents complex and challenging work. This LTP has brought together information from a variety of sources within different areas of expertise.

Best practice options have, as far as possible, identified the future work packages necessary to steer the site to a safe and decommissioned state. These have been costed and scheduled to reflect the site’s emphasis on prioritisation throughout the period of decommissioning, and value to the taxpayer.

Attention has been given to maintaining and improving on the high standards of safety, quality and care for the environment with which British Nuclear Group at Berkeley has been associated over many years.

The plans take into account the need for continued support to the local economy and the importance of engagement with regulatory bodies and local stakeholders.

Partial site delicensing facilitates early clearance of redundant office accommodation and also is a key enabler for the SSG to build on the recommendations of the Berkeley Task Force for potental future uses of the site.

The focus of work in C&M Preps is the reduction of hazards on site by decontamination of all active areas and the safe retrieval, processing and encapsulation of radiological waste through the AWVR plant and the systematic demolition of redundant site buildings.

All waste remaining on site during C&M will have been appropriately processed, safely and compliantly packaged in a passive state for the period of quiescent storage.

During C&M the site will remain in a quiescent state. Monitoring and maintenance of the reactor buildings and site will constitute the primary activities, including work to ensure the integrity of the buildings. Stored ILW will be transported to a national repository when it becomes available.

FSC will see the site cleared of the reactor buildings and all remaining hazards. All radiological waste will be removed to a repository and non-hazardous waste recycled and used for backfilling on site whenever possible.

At the end of the lifecycle the site will be returned to a Greenfield site, having been resurveyed to demonstrate that ‘no danger to the public’ exists, allowing the site licence to be withdrawn and the land released for alternative use.
