ES Group participated in a Coordination Research Meeting on Developing a PIRT and Performing a Benchmarks for In-Vessel Melt Retention
ES Group participated in a First Coordination Research Meeting (CRP) on Developing a Phenomena Identification and Ranking Table (PIRT) and a Validation Matrix and Performing a Benchmarks for In-Vessel Melt Retention.
The meeting took place at International Atomic Energy Agency (IAEA) Headquarters in Vienna (Austria) from 13 to 17 December 2021. The event was part of the coordinated research project IAEA J46002 with the participation of scientists from Austria, Bulgaria, Canada, China, Germany, Lithuania, Germany, Pakistan, South Korea, Russia, Slovakia, Ukraine, Finland, France, the Czech Republic and Sweden and others.
The purpose of the event was to develop plans for the proposed research by individual participants, its correlation with the overall objectives of the research project and to promote interaction between participants. Discussions were held during the meeting to facilitate the implementation of further project tasks.
ES Group was represented by Oleksandr Mazurok, Technical Director (physically) and Oleg Kocharyants, Head of NPP Safety Analysis Department (virtually). Oleksandr Mazurok is the chief scientific researcher from the company in this project and on the first day of the meeting he gave a presentation on the results of the work performed over the past year. Among such results were noted, in particular, consideration of proposals to PIRT, development of the MELCOR calculation model for the VVER-1000 integral benchmark, etc.
Based on the presentations and discussions, conclusions were drawn and an action plan of the participants for the next year was determined. In particular, а decision was made to involve ES Group specialists in the benchmark for the experimental study of critical heat flow at an experimental plant located in China.
