  • © 2017 by American Nuclear Society. All rights reserved. Different approaches have been provided by the US Nuclear Regulatory Commission for addressing the concerns raised by the GSI-191. The approaches proposed by the STPNOC pilot plant adopted deterministic thermal-hydraulic calculations supported by system codes to simulate the plant response under numerous configurations and plant conditions. The results obtained supported the Probabilistic Risk Assessment analysis, and helped the resolution of the GSI-191, proving the importance of selecting and using specialized system codes and modeling technique to perform realistic simulations of the reactor system in support of both deterministic and risk-informed methods.
