In 2012, following a proposal from Japan, the Committee on the Safety of Nuclear Installations (CSNI) decided to initiate a joint project to conduct a study of the accident progression for the Fukushima Daiichi NPS units 1-3 accident, called the Benchmark Study of the Accident at the Fukushima Daiichi Nuclear Power Station (BSAF). Sixteen organisations from eight countries (France, Germany, Korea, Russia, Spain, Switzerland, the United States, and Japan) joined the project. The objective of the first phase of the project was to focus on the first six days of the accident to analyse accident progression and estimate the current status inside RPVs and PCVs of units 1-3 of Fukushima Daiichi Nuclear Power Station; improve methods and models of severe accident (SA) codes and reduce uncertainties in SA analysis; and provide Japan with useful information for decommissioning activities at Fukushima Daiichi NPP.
This summary report presents the major technical results of the NEA BSAF project.
