In April 2023, at the site of SRPA "Impulse", acceptance tests of the in-core monitoring system (SVRK-M2) for power unit No. 3 of the Rivne NPP were successfully carried out, which includes a national calculation complex for neutron-physical and thermohydraulic parameters of the core and reactor plant the “ImCore”.
The test results confirmed the implementation and operability of the system functions in full, including the function "Forecasting the state of the core" and all service functions in accordance with the terms of reference.
SVRK-M2 integrates the experience and all regulatory requirements for SVRK, taking into account maneuvering and forecasting, namely:
Unlike SVRK of foreign manufacturers, the development of SVRK-M2 was built as a development of a domestic product from a single manufacturer of all components. For the development of SVRK-M2, the most advanced computing platforms, tools and methods for solving physical and mathematical problems were used.
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 SVRK-M2 fully complies with the requirements of the terms of reference, norms, rules and standards for nuclear and radiation safety and is ready for delivery to RNPP.
In accordance with the plan, in May - July 2023, two projects for the implementation of SVRK-M2 with the national calculation complex "ImCore" are being implemented in parallel: at power unit No. 3 of the Rivne NPP and at power unit No. 3 of the South-Ukrainian NPP.
