The device is applicable for detection of fuel debris at damaged Fukushima NPP.
Mitsubishi Research Institute (Japan) selected RosRAO (as a Project leader) in consortium with TENEX to arrange the feasibility study, the first phase of the Subsidy Program “Project of Decommissioning and Contaminated Water Management (Project of Development of Fundamental Technologies for Retrieval of Fuel Debris and Internal Structures (Development of Small Neutron Detectors))”.
Consortium led by RosRAO propose to create an integral high-sensitive neutron detector with self-tuning depending on gamma dose rate and temperature.
The goal of the Project is to establish a method of detecting and identifying fuel debris more accurately for the needs of Fukushima Daiichi NPP.
Decision on the neutron detection system development is planning to be made based on the results of the feasibility studies.
RosRAO is Rosatom's company, RF nationwide operator for RW management and nuclear decommissioning.TENEX is Rosatom’s company, chief coompany for overseas back-end product and service sales.To conduct the project RosRAO is planning to contract the Russian Scientific Center (RSC) – A.I. Leipunskiy IPPE to provide R&D supervision.
"The project is aimed at development of methods for investigation of the reactor interior at NPP Fukushima Daiichi in order to identify fuel debris by the neutron ionization. As a result of project implementation the Japanese party expects to receive a sample system for detection of fuel debris and arrange tests at one of the NPP units. Currently all participants commence the pre-project investigations, their results will allow the Japanese party to decide on further performance of the project", — comments Sergei Floria, Head of RosRAO's Project Management Office.
RosRAO has been involved in the Project of Decommissioning and Contaminated Water Management since 2014. In august 2014 RosRAO have been adopted by MRI Inc. as a subsidized operating entity to conduct the Demonstration Project for Verification Tests of Tritium Separation Technologies.
