INTEGRAL COMPUTER CODE SOCRAT

IBRAE RAN in cooperation with leading nuclear industry organizations (VNIIEF, SPbAEP, NRC ‘Kurchatov Institute’, OKB ‘GIDROPRESS’, Atomenergoproekt, IPPE and Electrogorsk Research & Engineering Center for NPP Safety (JSC ‘EREC’)) developed a through computer code, named SOCRAT, that enables simulation of the processes that occur during severe beyond-design-basis accidents at water-cooled reactors (VVER, BWR, PWR, and KLT-40S) starting from the initial event and ending with release of radionuclides to the environment.

In 2010, the basic version of the integral SOCRAT Code was certified by Rostechnadzor of Russia. The SOCRAT Code is widely used by leading Russian R & D organizations for: analysis of severe beyond-design-basis accidents at NPPs with thermal water-cooled reactors; justification of hydrogen safety and the efficiency of molten core catchers; analysis of the efficiency of passive safety systems at VVER and AES-2006-design NPPs in operation and under construction in Russia and abroad (India, China).
