Abstract
This report analyzes the effect of the plant specific EOPs for the RCPs during a hypothetical IBLOCA in Vandellòs II NPP, a 3 loop Westinghouse design reactor. The scenarios simulated are:
- Cold leg IBLOCA simulating the rupture of an accumulators connection to the RCS;
- Hot leg IBLOCA simulating the rupture of the pressurizer surge line connection to the RCS.
The selection of an intermediate break size conforms to the risk-informed approach for the assessment of the ECCS performance.
The RELAP5/MOD3.3 model of Vandellòs II NPP was developed by the Advanced Nuclear Technologies (ANT) group at the Universitat Politècnica de Catalunya (UPC).
