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

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

Operational Safety Assessment

• Volume 1: Non-radiological and construction
• Volume 2: Normal operations
• Volume 3: Accident safety assessment
• Volume 4: Criticality safety assessment
• Generic Operational Environmental Safety Assessment

Transport Safety Assessment

• Generic Transport System Safety Assessment
• Transport Package Safety Report

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
