The IAEA regional training course №8 devoted to the analysis of the safety of passive systems was held from 8 to 12 July at Rosatom Technical Academy in Obninsk. This course continued the technical cooperation project RER/9/144 of Rosatom State Atomic Energy Corporation and the International Atomic Energy Agency: “ Building Capacity for Infrastructure Development and Safety Assessment of Water Cooled Water Moderated Power Reactor Technology with Advanced Safety Features.”
A series of lectures on the course was delivered by an expert of the IAEA, representative of the Department of Nuclear Safety and Security, Division of Nuclear Installation Safety, Mr. Martin
Gajdos. The Russian Federation was represented by seven experts from three organizations: OKB GIDROPRESS JSC (Podolsk), Aleksandrov’s Research Institute (Sosnovy Bor), FSUE RFNC-VNIIEF (Sarov) as developers and users of the KORSAR and LOGOS computer codes applied for safety assessment of reactor facilities, as well as experts from the Rosatom Technical Academy (Obninsk).
Eleven specialists from six countries: Bulgaria, the Czech Republic, Hungary, Slovakia, Turkey and Russian Federation took part in the training course as trainees and represented various organizations from their countries – regulatory bodies, technical support organizations, research centers, and nuclear power plant operators.
Experts presented talks on general approaches to assessing the safety of reactor systems with passive safety systems, safety assessment procedures using best estimate codes and CFD codes, calculation codes and their numerical models, verification results, examination and certification of improved assessment codes, etc. Most of the agenda was devoted to practical exercises using demo versions of the KORSAR and LOGOS codes.
Following the results of a rich five-day programme, participants received up-to-date information on international standards for designing reactor plants and got acquainted with the description of best practices for analyzing the safety of modern pressurized water reactors and gained skills in using Russian design calculation codes to justify their safety.
