TENEX in a consortium with V.G. Khlopin Radium Institute (KRI), Research Institute of Atomic Reactors (RIAR) and FSUE RosRAO have successfully fulfilled the first phase of works on the research project of the ageing properties of fuel debris. The project is subsidized by the Japanese government; its results will be used in the further works of post-accident clean-up at Fukushima Daiichi NPP. The project is managed by Mitsubishi Research Institute, Inc., Japan.
The research resulted in the development of methods allowing creating model active samples of Fukushima Daiichi fuel debris, worked out on the basis of the prior study of Chernobyl corium and lava samples.
During the second phase, it is planned to produce the model samples of fuel debris necessary for further research, and to develop an ageing model describing the change of its properties over time. The project is to be finalized by March 2019.
