Within the framework of CORMIT-II International Project implemented jointly with Toshiba Energy Systems & Solutions Corporation (Japan) through Marubeni Utility Services, Ltd., on 27-29 January 2020, the next scheduled meeting of Japanese and Kazakhstani technical experts was hold. Based on Agreement for 2019-2020, on 24 December 2019, RT-9 test has successfully been carried out at the LAVA-B test-bench, which resulted the data on interaction between corium and refractory materials of two types – alumina and zirconium oxide. In the framework of this meeting, Japanese colleagues visited VCG-135 and LAVA-B experimental facilities, technological systems of the ANGARA facility. During the visit, TOSHIBA’s experts reviewed results of tests and material research relating RT-8 and RT-9 tests, series of the small-scale studies as well as extent of preparations for the next similar RT-10 experiment, which is going to be carried out in February 2020. While the meeting, Kazakhstani and Japanese experts also discussed organizational and technical issues regarding the next Agreement for 2020-2021, under which it is planned to implement 2 more full-scale experiments RT-11 and RT-12.
* CORMIT-II Project is aimed at studying of interaction between molten materials of the core (corium) of a light-water reactor and refractory materials in a case of severe accident. Cooperation of Kazakhstani and Japanese specialists lies in implementation of the series experimental and material studies of results of a contact between corium and different heat-resistant materials (e.g. zirconia dioxide and alumina) under conditions simulating residual energy release in corium. The practical part of research work is carried out at the experimental complex of the Institute of Atomic Energy Branch. Large-scale experiments are carried out at the LAVA-B test-bench of the ANGARA facility, small-scaled one – at the VCG-135 facility. All the facilities are located at the territory of the Research Reactor Complex “Baikal-1”.
