RELAP5 thermal-hydraulic analyses of pressurized thermal shock sequences for the H. B. Robinson Unit 2 pressurized water reactor

Thermal-hydraulic analyses of fourteen hypothetical pressurized thermal shock (PTS) scenarios for the H.B. Robinson, Unit 2 pressurized water reactor were performed using the RELAP5 computer code. The scenarios, which were developed at Oak Ridge National Laboratory (ORNL), contain significant conservatisms concerning equipment failures, operator actions, or both.
