An investigation of reator core isolation cooling (RCIC) turbine exhaust line dynamics at lasalle nuclear generating station

摘要

The RELAP5 Mod 3.1 computer code has been utilized to study the causes of exhaust line rupture disk actuation that occurred without indication of overpressure condidtions. A series of cases have been investigated to determine the conditions in the RCIC upstream steam supply as well as the exhaust piping that would lead to dynamic behavior capable of causing exhaust system rupture disk failure.
