The Benchmark Study of the Accident at the Fukushima Daiichi Nuclear Power Plant (BSAF) Project has been established to improve severe accident (SA) codes and analyse accident progression and current core status in detail for preparation of fuel debris removal, as a part of the R&D projects for the mid- to long-term response for decommissioning of the Fukushima Daiichi Nuclear Power Station (NPS), Units 1 to 4.
Hosted by the Operating Agent Japan Atomic Energy Agency (JAEA) in collaboration with other Japanese institutions such as the Institute of Applied Energy (IAE), Japan Nuclear Energy Safety Organization (JNES), Central Research Institute of Electric Power Industry (CRIEPI) and supported by Tokyo Electric Power Company (TEPCO) and other Japanese industry partners, the project brings together international experts to advance the understanding of the phenomena of severe accident behaviour specific to the Fukushima Daiichi NPS accident while also improving the methods and codes for modelling such behaviour.
A phased approach will be applied in the NEA benchmark exercise. The range of analysis for this first phase will include the following:
The first phase of this project to include the initial benchmark calculations runs for 1.5 years and includes the following countries:
November 2012 to September 2014
