1 NDA Strategy for Site Restoration
NuLeaf Seminar 22 June 2011 Dr Anna Clark Head of Site Restoration

2 Scope of Site Restoration

3 IAEA decommissioning strategies
Immediate dismantling Deferred dismantling Entombment

4 NDA Strategy: Strategic questions

5 NDA Strategy: What level of restoration do we aim for?
Rely on institutional controls to manage risks Clean up every trace of industrial use WASTE ARISING LEVEL OF INTERVENTION RESTRICTIONS ON LAND USE COST 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

6 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

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

8 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

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

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

11 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

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

13 NDA Strategy for Integrated Waste Management
NuLeaf Seminar 22 June 2011 Dr James McKinney Head of Integrated Waste Management

14 Integrated Waste Management (Site Restoration etc)
IWM THEME – 3 Topics NDA STRATEGY Integrated Waste Management Other themes (Site Restoration etc) THEME Higher Activity Wastes Lower Activity Wastes Non-Radioactive & Hazardous Wastes TOPIC Liquid & Gaseous Discharges Solid LLW Management

15 Waste in the NDA Estate - What is it?
LLW Long-lived ILW Vitrified HLW

16 Past / Current practices – Baseline Plans
GDF HAW Package (grout) Store LLW Package (grout) LLWR Liquid and Gaseous Waste Discharges Non-Radioactive and Hazardous Waste Landfill

17 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!

18 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)

19 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

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)

21 Outline

22 Desired Practices – SII approach
Past Approach Strategy II 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

23 Bill Hamilton – Head of Stakeholder Communications

24 Socio-economic Progress – Priority Areas
West Cumbria Port of Workington West Cumbria Transport Study West Cumbria Blueprint and Spatial Strategy Caithness and North Sutherland Caithness Chamber of Commerce Scrabster Harbour Anglesey and Meirionnydd Energy Island Projects Gretna-Lockerbie-Annan corridor Chapelcross Transition Support Project

25 Socio-economic Progress – Other areas
Hinkley Point Bridgewater College Oldbury/Berkeley Energy Gloucester

26 New delivery model NDA will retain a central budget for transformational projects SLC contractors will be held to account for delivery of soc-ec support Applications will increasingly be submitted to SLC’s SLC’s to assess and submit relevant ones to NDA Socio-economic Panel and Committee have been dissolved Applications approved by Jon Phillips (up to 500k) or Tony Fountain and Government (500k plus)

27 Cont…. Dounreay SLC allocation increases
Magnox Ltd undertaking a socio-economic impact assessment of its work programme Socio-economic development Plan due late September

28 UK National Engagement Plan 2011/12
Plan was published in May 2011 Plan will show stakeholders what engagement opportunities there are over the next year The plan is split into sections reflecting the strategic themes used in our Strategy Plan will be continuously updated A national event is planned for November 2011 We welcome input and feedback at anytime
