Abstract

Activities within the frame of the IAEA’s Technical Working Group on Advanced Technologies for HWRs (TWG-HWR) are conducted in a project within the IAEA’s sub- program on nuclear power reactor technology development. One of the activities recommended by the TWG-HWR was an international collaborative standard problem (ICSP) entitled “Comparison of HWR thermal-hydraulic code predictions with SBLOCA experimental data”. Its main objective is to enhance the confidence in the predictions made by computer codes used in different countries for thermal-hydraulics safety analyses through their inter-comparison and validation. Two RD-14M Small Break Loss Of Coolant Accident (SBLOCA) tests, simulating HWR LOCA behavior, that were conducted by Atomic Energy of Canada Ltd (AECL) were selected for this ICSP project. This paper provides some results and lessons learned from the ICSP.
