Analysis of Information from Reactor Building and Containment Vessel and Water Sampling in Fukushima Daiichi NPS (1F)
Joint project

The main objective of the ARC-F project is to consolidate participants’ and experts’ views that contribute to deeper understanding of the severe accident progression and the status inside reactor buildings and containment vessels of the Fukushima Daiichi NPS. This is mainly achieved by analyzing data and information from the Fukushima Daiichi NPS. In addition, the project also aims to establish a framework for sharing the information between Japanese organizations and international experts in reactor safety.

The ARC-F project runs between January 2019 to December 2021 and is supported by 12 countries with 24 partners. (Canada (CNL), China (SNPSDC), Finland (STUK and VTT), France (CEA, EDF and IRSN), Germany (GRS), Korea (KAERI and KINS), Russia (ROSATOM jointly with IBRAE), Spain (CSN), Sweden (SSM), Switzerland (PSI), United States (DOE, EPRI and NRC), Japan (CRIEPI, IAE, NRA, JAEA)) The project includes 3 tasks. The first task is to refine analysis for accident scenarios and associated fission-product transport and dispersion. The second task is to compile and manage data and information on the Fukushima Daiichi NPS accident, including information from JAEA’s own activities, under the technical and financial support of the Nuclear Regulation Authority (NRA) of Japan. The third task is to discuss future long-term projects relevant to the Fukushima Daiichi NPS accident.
