NDA Strategy:What level of restoration do we aim for?
Clean up every trace of industrial use
Rely on institutional controls to manage risks
RESTRICTIONS ON LAND USE
LEVEL OF INTERVENTION
WASTE ARISING
• Restore site to a condition suitable for its next planned use
• To delicense, reduce radioactive contamination to a level suitable for any foreseeable future use
COST

NDA Strategy:What level of restoration do we aim for?
• Site End State determined by a case-specific assessment
• Site End State definitions remain flexible until planning commences for final stages of restoration
• Review Site End States if and when necessary as restoration progresses
![Page 7: NDA Strategy for Site Restoration NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration.](https://reader036.fdocuments.us/reader036/viewer/2022062417/5515fb5c550346cf6f8b58d1/html5/thumbnails/7.jpg)
7
NDA Strategy:What level of restoration do we aim for?
• Define Interim States
– milestone or decision point in site restoration programme, typically marked by a stepped reduction in risk or hazard
![Page 8: NDA Strategy for Site Restoration NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration.](https://reader036.fdocuments.us/reader036/viewer/2022062417/5515fb5c550346cf6f8b58d1/html5/thumbnails/8.jpg)

NDA Strategy:How do we restore our sites?
Strategic options for decommissioning and land quality management:
• In-situ (manage or dispose in original location)
• Ex-situ (remove prior to management or disposal)
• On-site disposal facilities
![Page 9: NDA Strategy for Site Restoration NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration.](https://reader036.fdocuments.us/reader036/viewer/2022062417/5515fb5c550346cf6f8b58d1/html5/thumbnails/9.jpg)
9
NDA Strategy:When do we restore our sites?
• Intolerable risk - continuous action until risk at least tolerable
• Ensure tolerable risks do not become intolerable
• Balance range of relevant factors
![Page 10: NDA Strategy for Site Restoration NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration.](https://reader036.fdocuments.us/reader036/viewer/2022062417/5515fb5c550346cf6f8b58d1/html5/thumbnails/10.jpg)
10
NDA Strategy:When do we restore our sites?
• Undertake restoration as soon as reasonably practicable
– Preference for continuous decommissioning
• Commence POCO on cessation of operations
• Act proportionately to ensure net level of risk does not increase in the long-term
• Balance range of relevant factors
![Page 11: NDA Strategy for Site Restoration NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration.](https://reader036.fdocuments.us/reader036/viewer/2022062417/5515fb5c550346cf6f8b58d1/html5/thumbnails/11.jpg)

Continuing strategy development
We will:
• discuss implications of delicensing with Government and regulators
• look at role of other forms of institutional control in managing residual contamination
• further underpin strategic options
– in-situ or ex-situ
– continuous or deferred
• develop set of relevant factors for consideration during decision-making
• capture enduring prioritisation process
• define Interim States
• explore opportunities for early re-use of a site, or part of a site
![Page 12: NDA Strategy for Site Restoration NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration.](https://reader036.fdocuments.us/reader036/viewer/2022062417/5515fb5c550346cf6f8b58d1/html5/thumbnails/12.jpg)
12
Role of Local Authorities
• Planning Regime – form of institutional control for residual contamination
– Input to Site Restoration Theme Overview Group
• Local authority development plans
– Influence Interim States
• NDA project to articulate Interim States implicit in current lifetime plans
– Local Authorities to be engaged on how Interim States might be presented

Desired Practices – Drivers for change
• Policy
• Waste hierarchy
• Consideration of whole lifecycle
• Improvement notices
• Stakeholder involvement
• Costs and opportunities
• Proximity principle…
• Supply chain and open market
• Learning from experience!
![Page 18: NDA Strategy for Site Restoration NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration.](https://reader036.fdocuments.us/reader036/viewer/2022062417/5515fb5c550346cf6f8b58d1/html5/thumbnails/18.jpg)

Desired Practices – Drivers for change
NDA’s Unique Role:
• MRWS
• Deliver and implement a UK LLW Strategy for the nuclear industry
• Scottish HAW Policy - The policy is for the long-term management of higher radioactivity wastes in near-surface facilities
• Delivery partner for UK Strategy for Radioactive Discharges
• Working with others
(Role has developed subsequent to the Energy Act)

Integrated waste management – key messages
• Objective: Ensure that wastes are managed in a manner that protects people and the environment, now and in the future, and in ways that comply with Government policies and provide value for money
• Address the whole waste lifecycle - move away from a focus on disposal
• Risk reduction as a priority- waste in ageing storage facilities
• Centralised and multi-site approaches - considered where advantageous
• Application of waste hierarchy - value for money and affordability
![Page 20: NDA Strategy for Site Restoration NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration.](https://reader036.fdocuments.us/reader036/viewer/2022062417/5515fb5c550346cf6f8b58d1/html5/thumbnails/20.jpg)
20
Integrated waste management – key messages
• Diverse solutions
• Waste management should be integrated- traditional classification not starting
point
• Seek opportunities to do things better - and deliver them – e.g. thermal treatment
• Opportunities at classification boundaries- ex. decay storage of ILW; alternative
disposal options (graphite)

Desired Practices – SII approach
• Each site looks after its own waste, processing & storage
• Limited range of options “if in doubt grout”
• Straight jacket of waste category boundaries
• Consolidation and co-location as appropriate
• Integrated waste processing solutions ‘take the plant to the waste” or “take the waste to the plant”
• Waste specific approach– What is it?– Best treatment and disposal?
• Flexibility – Decay storage, VLLW disposal, risk based approach
Past Approach Strategy II Approach
