NDA Strategy:
Strategic questions
Site
Restoration
Strategy
No restoration
What level of
restoration are we
aiming for?
In-situ
Continuous
How do we do it?
Squeaky clean
When do we do it?
Ex-situ
Deferred
Pace
Priority
4
NDA Strategy:
What level of restoration do we aim for?
Clean up
every trace of
industrial use
Rely on institutional
controls to manage
risks
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
5
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
6
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
7
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
8
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
9
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
10
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 decisionmaking
• capture enduring prioritisation process
• define Interim States
• explore opportunities for early re-use of a site, or part of a site
11
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!
17
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)
18
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
19
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)
20
Outline
21
Desired Practices – SII approach
Past Approach
•
Each site looks after its own
waste, processing & storage
Strategy II Approach
•
Consolidation and co-location
as appropriate
•
Integrated waste processing
solutions ‘take the plant to the
waste” or “take the waste to
the plant”
•
Limited range of options “if
in doubt grout”
•
Waste specific approach
– What is it?
– Best treatment and disposal?
•
Straight jacket of waste
category boundaries
•
Flexibility – Decay storage,
VLLW disposal, risk based
approach

25
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)
26
Cont….
•
Dounreay SLC allocation increases
•
Magnox Ltd undertaking a socio-economic impact assessment of
its work programme
•
Socio-economic development Plan due late September
27
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
