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 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
