ACCEPTANCE TESTING OF THE IN-CORE MONITORING SYSTEM FOR POWER UNIT No. 2 RIVNE NPP WAS CARRIED OUT

In march 2024, at the SRPA ”Impulse” test site, acceptance successfully tests of a complex of hardware and upper-level software of a modified in-core monitoring system (UL SVRK-M2) for power unit No. 2 of the Rivne NPP.

UL SVRK-M2 provides:

• Control of mixed loads with fuel of any suppliers and fuel assemblies with different fuel column heights;
• Fuel profiling in both axial and radial terms;
• Possibility of direct control of linear energy release at the level of fuel elements;
• Electronic album of neutron-physical indicators taking into account the predictive functions of the system;
• Information support for the operator in power maneuvering modes

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.
