2014 PGSFR Safety Analysis for Loss of Flow

  • 1. Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)

Description

The PGSFR consists of the PHTS (Primary Heat Transport System), the IHTS (Intermediate Heat Transport System), and the DHRS (Decay Heat Removal System). A LOF (Loss Of Flow) accident has been investigated for a safety evaluation of the PGSFR using the MARSLMR code. The safety analysis is evaluated by a CDF (Cumulative Damage Fraction). In case of the LOF accident, the tentative safety criterion is the CDF of under 0.05. The LOF accident has been evaluated in the PGSFR using MARS-LMR. The accident was initiated by both of PHTS pump trip. In the results, the CDF was predicted below a tentative safety criterion of 0.05 with a sufficient margin. The DHRS acceptably functioned for removing the core decay heat during long-term cooling period
