ACCEPTANCE TESTING OF SOFTWARE AND HARDWARE FOR MODIFICATION OF ICMS WITH INTEGRATION OF A BEACON-TSM PHYSICAL CALCULATION SUBSYSTEM TO MONITOR A CORE WITH TVS-WR FUEL HAS BEEN CARRIED OUT SUCCESSFULLY

Within the framework of work by SE “NNEGC “Energoatom” to diversify sources of nuclear fuel supplies for Ukrainian NPPs and in accordance with the document “Programme of actions to implement modernized nuclear fuel manufactured by Westinghouse for unit 3 of SS RNPP”, software and hardware for modification of ICMS with integration of a BEACON-TSM neutron-physical calculation subsystem have been developed at SRPA “Impulse”.

Modified ICMS-М assures monitoring of thermohydraulic and neutron-physical characteristics of an RF under the conditions of a wide range of steady and mixed fuel columns of RF’s cores having fuel assemblies by different manufacturers.

From 15 to 17 December 2021, acceptance testing of modified ICMS-М with integration of a BEACON-TSM neutron-physical calculation subsystem was carried out at the site of PJSC “SRPA “Impulse”.

The acceptance commission consisting of representatives of Rivne NPP, State Scientific and Technical Centre for Nuclear and Radiation Safety, and PJSC “SRPA “Impulse” carried out acceptance testing of software and hardware for modification of ICMS for meeting the requirements of the terms of reference and the normative documentation for nuclear and radiation safety. Based on the results of the testing, the following was confirmed: the modified SVRK-M meets the requirements of the terms of reference, the design documentation, the normative documentation and is ready to be supplied to unit 3 of Rivne NPP.
