Abstract

This paper outlines the characteristic features and salient results of a series of experiments conducted in the LOBI-MOD2 test facility to assess the effectiveness of intentional primary cooling system depressurisation, which is being investigated as a potential Pressurised Water Reactor (PWR) accident management strategy. It was found that the effectiveness of this strategy is strongly influenced by the PORV discharge capacity and by the HPIS and/or the AIS delivery characteristics. Although test conditions were strictly pertinent to PWRs of current design, the underlying thermal-hydraulic phenomenologies are nevertheless of general interest for the development of advanced reactor concepts.
