Abstract

This report is developed by the State Nuclear Regulatory Inspectorate of Ukraine (SNRIU) and its technical support organization, the State Scientific and Technical Center for Nuclear and Radiation Safety of Ukraine (SSTC NRS), under Implementing Agreement On Thermal-Hydraulic Code Applications And Maintenance Between The United States Nuclear Regulatory Commission and State Nuclear Regulatory Inspectorate of Ukraine (signed in 2014) in accordance with Article III, Section C, of the Agreement.
The report provides results of the comparison calculations conducted with application of SSTC NRS model of VVER-1000/V-320 for TRACE and RELAP5 computer codes. The calculation scenarios analyzed include design basis accidents and transients from several initiating event groups usually evaluated in safety analysis reports. Additionally, the plant incident with inadvertent opening of steam generator safety relief valve in hot shutdown is simulated.
