Integrated safety analysis code system (ISAS) application for accident sequence analyses

摘要

In the frame of the ITER Task 'Reference Accident Sequences', two accident sequences have been assessed to demonstrate the effectiveness of the use of integrated safety analysis code system (ISAS). The first one is a loss of coolant event in the divertor primary heat transfer system (ISAS). The first one is a loss of coolant event in the divertor primary heat transfer system (DV PHTS) towards the vacuum vessel containment during normal plasma burn; the second one is a loss of coolant event in the DV PHTS towards the lower vault during baking condition.
