In December 2023, acceptance tests of the upper level of the modified in-core monitoring system of power unit No. 4 of the Rivne NPP (UL SVRK-M2) were successfully carried out at the of SRPA "Impulse" test site.
UL SVRK-M2 performs diversification of the calculation of the neutron-physical parameters of the core using two software systems: "Beacon-TSM" (Westinghouse) and the national calculation complex "ImCore" (SRPA ”Impulse”). Software that implements the calculation of the thermohydraulic parameters of the reactor plant and all other functions, and equipment of the upper level - SRPA ”Impulse” production.
UL SVRK-M2 provides:
Based on the results of the work, the acceptance committee, consisting of representatives of the RNPP, State Nuclear Regulatory Inspectorate of Ukraine and SRPA “Impulse”, concluded that UL SVRK-M2 fully complies with the requirements of technical specifications, norms, rules and standards for nuclear and radiation safety, including the requirement for cyber protection, and is ready for delivery to the Rivne NPP.
