Long-term safety

Long-term safety of a nuclear waste disposal facility is based on long-term containment and isolation as well as on limitation of radionuclide transport.

Long-term safety

Assessment of long-term safety and compilation of a safety case are a key part of all phases of a nuclear waste disposal programme: selection of a disposal site, design of underground facilities and engineered barriers and construction, operation and closure of the facilities. A safety case is needed in the different phases for licensing, and it can be utilised in the guidance of research, design and implementation.

Our expertise covers both low and intermediate level waste (LILW) and high-level waste (HLW) disposal and the following areas:

  • formulation of safety case plans
  • requirements management
  • analyses of features, events and processes (FEPs)
  • analyses of impacts of construction and operation on long-term safety
  • uncertainty management and formulation of scenarios
  • radionuclide release analyses, including radionuclide transport modelling
  • application of natural analogues
  • document management

The in-house knowledge of the performance of engineered clay barriers and related modelling  as well as repository construction and production  supports the long-term safety experts to get a good overall understanding of aspects affecting long-term safety.

Our experts specialising in long-term safety will help you evaluate the long-term impacts of your disposal solution and compile a safety case to demonstrate the safety of the facility in various stages of the project.

We also provide consulting services on topics such as data management, site investigations, monitoring data, rock mass classifications, as well as training.
