Stakeholder engagement

• Project has just been initiated and involves Magnox and EdF Energy sites

• The work will take into consideration other Magnox strategic programmes

• Programme rather than individual task approach to Stakeholder Engagement

ILW / LLW Cross-Boundary Wastes

Slides courtesy of LLWR

13

ILW / LLW Cross-Boundary wastes defined as those wastes at either side of the LLW radiological classification boundary that could practicably be

managed either as LLW or ILW.

• Wide range of management approaches can be employed (e.g. decay storage, decontamination, encapsulation, optimised disposal etc.)

• Similarly diverse range of factors used by SLCs to optioneer management approach for their wastes (e.g. cost, schedule, ALARP, environmental factors, waste characteristics, availability of waste route etc.)

• SLCs have indicated that there is an absence of centralised guidance on the factors to consider when making waste management decisions for cross-boundary wastes.

• LLWR led task

Pros / Cons of management approaches

Decision-making logic (“toolkit”) showing relationships between factors and if / how combinations of factors drive

certain decisions.

OUTPUT – Position paper and recommendations on the management of waste close to LLW / ILW categorisation boundary.
