Consultancy Meeting for the Collaborative Project on Review of Innovative Reactor Concepts for Prevention of Severe Accidents and Mitigation of their Consequences (RISC)
The Collaborative Project (CP) on Review of Innovative Reactor Concepts for Prevention of Severe Accidents and Mitigation of their Consequences (RISC) is being implemented as activity 2.2 under Task 2 "Innovations" of the INPRO Action Plan 2014-2015.
This project aims to demonstrate that technical and institutional innovations related to advanced reactor designs provide continued progress to ultimately meet a design requirement to practically exclude releases warranting relocation or evacuation outside NPP sites in case of a severe accident.
Its major scope is as follows:
- To review advanced reactor concepts to measure the progress of design concepts that claim to satisfy the above safety design requirement.
- To undertake a pilot exercise to assess these concepts in selected reactor designs using the INPRO Methodology (reactor safety area) and provide recommendations for further development of the INPRO Methodology.
- To explore the role of multilateral cooperation in RD&D programmes associated with enhancing the safety of the global Nuclear Energy System.
Existing or proposed advanced nuclear energy systems will be evaluated with respect to the above INPRO requirement, i.e. no need for evacuation beyond the NPP site following any type of accident. The efforts undertaken to verify the effectiveness of the systems will be documented.
The target audience are interested groups of the public, decision makers, technical experts, and scientists working in the area of nuclear power.
The first meeting had been held in 2014 to discuss and finalize the Terms of Reference of this INPRO Collaborative Project.
Several activities are envisaged:
1) Review of advanced reactor concepts (e.g., Gen-III, Gen-IV, concepts that were investigated following the Three Mile Islands and Chernobyl accidents, etc.) with a focus on technologies that claim to satisfy the above requirements.
2) Using the INPRO methodology, perform an assessment of one or more of these concepts using an assumed nuclear power system, and provide recommendations on the need to further develop the concept. Proof is required that the ‘last barrier’ does not fail under multiple simultaneous natural and technical disasters or human error.
3) Investigation of the role of multilateral cooperation (e.g., unification of safety requirements) in enhancing the safety of the global nuclear energy system.
