Waste Processing and Interim Storage

Review of the underpinning and justification for the 500 year integrity target placed on UK disposal containers for intermediate level waste (2014)

MCM has led a review for RWM to document the origins and supporting evidence for the intermediate level waste container integrity requirements and re-evaluate their relevance. This has included quantification and formulation in the context of the current GDF programme boundary conditions and to identify options for alternative solutions (other than placing the requirements on the waste container) to meeting the generic safety functions for the range of potential compatible engineered barriers to be used together with the range of potential intermediate level waste containers. As part of the review, definitions of waste container safety functions during each phase has been outlined, uncertainties associated with each phase have been identified and consideration of additional aspects relating to activities and conditions of waste packages during interim storage prior to transportation to a GDF have been introduced. A workshop was also held to preview the initial outputs of the review with invited experts and RWM staff. The outputs of the work will be used to develop a number of the recommendations that may lead to improved definition, justification and quantification of the current waste container integrity target.

MCM has been involved in projects to help develop various aspects of the South African Spent Fuel management strategy. Specific studies have been carried out on:

  • Storage Options for Spent Fuel
  • Multi-attribute Analysis of Integrated Management Systems for Spent Fuel
  • A Comprehensive Strategy for Management of Spent Fuel in South Africa
  • Viability of Indigenous Reprocessing of Spent Fuel
