Site Restoration
Site Restoration - Objective
To return our designated sites to societal use
NDA’s main function is to carry out decommissioning and clean-up
Site Restoration is the driving strategy the other strategies provide support
Site Restoration Scope
• Site Restoration covers three key activities required to deliver a site or facility through to a planned Site End State
– Decommissioning and Clean-UpCleaning out, dismantling and demolishing redundant facilities (from cessation of operations to demolition)
– Land Quality ManagementManaging contaminated ground and groundwater
– Site End StatesProviding credible objectives for the restoration of each site; defining the physical condition of a site when NDA has completed its mission
Site Restoration
• 2006 Strategy attempted to identify the main elements in the lifecycle scope
• Strategy II tries to focus more on the near term and saturates those projects where the risks are high
• Resources are constrained
Site Restoration - Challenge
Restoration of the UK’s nuclear legacy presents a major and time critical challenge; in 2009/10 the discounted future cost estimate amounts to £40.8 billion
– Legacy plants dating from late 1940’s and 1950’s– Large quantities of old corroding radioactive waste– Degrading infrastructure– Contaminated ground and / or groundwater at every NDA site
as a result of various land uses (not all nuclear)– Volume of ground estimated to be radioactively contaminated
exceeds (~x4) current UK low level waste disposal capacity.
Site Restoration – Key Messages
• Undertake Site Restoration as soon as reasonably practicable, taking account of all relevant factors
• Focus resource on reducing high risks to people and the environment
• Utilise Interim States for timely achievement of objectives
• Employ fit-for-purpose restoration objectives
• Ensure Site Restoration encourages the highest standards in health, safety, security and environmental performance, offers value for money and employs good practice
Question
• The NDA believes that our focus should be on Interim States and our decision on site end states should be made closer to the time when the next planned use is apparent
– What are your views on the NDA’s position?
– What attributes should any Interim State have, and which are particularly important to you and why?
– Does a focus on interim states raise any concerns?
– To what extent should local authorities be engaged in identifying interim states at sites?
Integrated Waste Management
Strategic objectives in waste management
• Our goals:– implement Government policies for radioactive waste and
decommissioning and comply with the requirements of the Energy Act 2004
– deliver effective waste management solutions to support the cleanup mission
• We have taken on wider responsibilities since Strategy 1:– UK-wide responsibility for Low Level Waste strategy and
implementation;– responsibility for implementing the UK Geological Disposal Facility;
and– responsibilities under Scottish policy to produce a higher activity
waste management strategy for Scotland
Risk reduction – legacy facilities
• We will continue to prioritise risk reduction by waste retrieval
• Earliest waste retrieval is paramount – the need for subsequent waste treatment and packaging in some instances is accepted
• The door is open for innovative waste treatment and packaging technology
Strategic points
• Diversified waste disposal
• Other Intermediate Level Waste opportunities
• Solid Low Level Waste Strategy
• Scottish policy for Higher Activity Waste
Diversified waste disposal
Pursuing flexibility, value for money and fit-for-purpose disposal solutions: moving away from the old UK waste disposal paradigm
• Optimising the use of LLWR– Landfill-type disposal of VLLW, on-, near- and off-site– Incineration for volume reduction– Waste hierarchy opportunities
• Optimising the use of the Geological Disposal Facility– Near surface disposal opportunities for Reactor Decommissioning
Waste (ILW)• Implications
– More locations– Earlier– Transport
Other Intermediate Level Waste opportunities
Challenging the old ideas
• Develop the opportunities to treat and store ILW in fewer locations
• New waste package concepts
• Thermal waste treatment: volume reduction, value for money, early immobilisation and fit-for-purpose wasteforms
• Waste transport infrastructure is the catalyst
Solid Low Level Waste strategy
We consulted upon UK Nuclear industry strategy for solid LLW in 2009. What did we learn?
• Respondents endorsed key themes of the strategy – eg waste hierarchy
• Early dialogue with stakeholders and local communities is essential to successful implementation
• Good waste management solutions consider local issues as well as national
Question
• What does the Integrated Waste Management Strategy mean for you in your area?
• What are the opportunities and/or the main hurdles to implementation and how they might be overcome (eg on ‘other ILW opportunities’)?
Spent Fuel Management
Magnox Context
Current Inventory: •Magnox fuel : 4500 te to be reprocessed, of which
– Wetted fuel ~500 te (Mostly at Sellafield)– Dry Fuel ~ 4000 te (at Reactor Sites, e.g. in cores)
It is important to control the amount of Magnox fuel stored in Ponds:
– Magnox Fuel can start to corrode after approximately 5 years in fuel ponds
Example of potential additions to inventory:– Dounreay Fast Reactor Breeder: < 45 te (i.e. 1% extra)– Wylfa and Oldbury extension : < 20 te (i.e. 0.5% extra)
Magnox – Main Issues
• Magnox Reprocessing uses oldest facilities– Increasingly expensive to maintain
• Risk of Early Plant Failure – Reprocessing process operates in series
• Single plant failure can slow / stop the whole process– Contingency work progressing but still immature– NDA has now set Failure Criteria / Strategic Tolerances for the
MOP associated with plant longevity, e.g. • Dissolver Life• Avoidance of new plant requiring major investment
Current Magnox Strategy
Deliver Magnox Operating Plan (MOP)– Extend power generation as far as possible – Predicted finish 2016
Maximise opportunities to incorporate other materials in reprocessing stream
– For some spent metal type fuels this is the only technically underpinned management option
Develop Contingency Options in event of plant failure– Fuel Drying and long term Dry Storage– Alternative options
Magnox Drying and Dry Storage
• Significant Investment in Fuel Drying and Dry Fuel Storage Project– Commenced during last half of 2007– Investment increased 2009/10– Further increase in investment planned for 2010/11
• Loosely based on metal fuel drying project completed at Hanford, USA.– Dried and dry stored 2100 te of pond stored metal fuel.
• Now incorporating the options to dry and dry store other fuel types, such as oxide and exotics
• Current reference oxide strategy– Reprocess contracted “Overseas” LWR fuel– Receive and manage AGR fuel
• ~3000te Historic Fuel will be reprocessed• ~3100 te Future Fuel will be stored and may be reprocessed• Need to keep extra space available if BE extend AGR station
lifetimes– Very small amount of corroded fuel – priority reprocessing
• Aim to achieve fuel management to maximise the cost benefit– E.g. by develop optimised lifecycle for AGR fuel
Oxide Reference Strategy
Oxide Fuel Credible Options
1. Reprocess minimum contracted fuel and stop– no new plant
2. Reprocess until the end-of-life of the existing plant
3. Reprocess all UK & Overseas fuel– Refurbish & replace plant as required– Eventually throughput circa 250 te p.a. from UK AGRs
4. Reprocess all UK & Overseas fuel – Consider extra business to offset costs and optimise use of the
assets– Refurbish & replace plant as required
5. Stop Repro – store, immobilise and dispose
NOTE: Current reference strategy placed between 1 & 2

Exotics Strategy / Issues
• Total Inventory liability (circa 500te)• Outside standard arrangements:
– transport, storage, reprocessing and disposal • Unique challenges
– Bespoke solutions required for some exotic fuels• TREAT – Could be reprocess or immobilise

PRODUCTS
Exotic Fuels Risks & Opportunities
• Multi-Track Plans for Fuels Needs to be Optimised for all fuel types:– Reprocess some fuels (e.g. Thorp Non-Standard)– Immobilise, Store and Dispose (e.g. PFR Fuels)
• Significant part of the inventory has technically immature solutions at present
• NDA wants to consider reprocessing exotic fuels using the existing NDA estate wide infrastructure – Where technology and logistics (timings) allow
Question
Magnox • Given we have a mature strategy that is clear and embedded in
policy, but delivery is at risk due to ageing assets, what are your views on NDA’s proposed approach?
Oxide• Are the identified options the right ones to be assessing?
• What will be the most important factors when assessing the strategic options?
