Corporate report: Generic Disposal System Safety Case for a Geological Disposal Facility: environmental safety assessment

This Post-Closure Safety Assessment (PCSA) presents the results of quantitative
assessments of the long-term environmental safety of radioactive waste disposal in a
geological disposal facility (GDF).



Corporate report: Generic Disposal System Safety Case for a Geological Disposal Facility: environmental and sustainability assessments

The Environmental and Sustainability Assessments are set out in 3 documents:

  • Generic Environmental Assessment
  • Generic Socio-Economic Assessment
  • Generic Health Impact Assessment


Corporate report: Generic Disposal System Safety Case for a Geological Disposal Facility: disposal system specification

The Disposal System Specification is described in four documents:

  • Disposal System Specification Part A: High Level Requirements
  • Disposal System Specification Part B: Technical Specification
  • Derived Inventory Report
  • Derived Inventory: Scenarios Report


Collection: Demonstrating the safety of a geological disposal facility (GDF)

Updated: Re-ordering of content on page

This suite of documents is designated as a ‘generic’ safety case: it is not site-specific as no site has yet been chosen for a geological disposal facility (GDF). It sets out how a GDF can be designed, constructed and operated safely, in compliance with regulatory guidance, in a range of geological environments. This safety case underpins a process for packaging waste ready for disposal in such a facility.

This latest update brings together:

  • a revised inventory for disposal
  • findings from a comprehensive, ongoing research programme
  • learning from facilities around the world.

This collection of documents is structured in the following way:

  • The overview provides a guide to the suite of safety case documents
  • There are three main safety case reports on transport, operational and environmental safety
  • There are a series of individual assessments for the different safety case reports. These are split into:
    • transport safety assessment
    • operational safety assessment
    • environmental safety assessment
    • environmental and sustainability assessments
  • There is a detailed specification for the disposal system
  • The design of the transport system and the disposal facility are described
  • Further information is provided in the associated knowledge base including specific research status reports


Research and analysis: Future of the sea: plastic pollution

This report summarises evidence on marine plastic pollution in the UK, its overseas territories and the global oceans. It explores:

  • what causes plastic pollution
  • how plastic pollution impacts the UK’s marine life, marine industries and human health
  • how plastic pollution will change in the future

It was commissioned as part of the Foresight Future of the sea project.
