Abstract
VERIFICATION AND DEVELOPMENT EXPERIENCE OF CORE MONITORING SYSTEM (CMS) PHYSICAL CALCULATION CODES FOR WATER COOLED WATER MODERATED REACTORS AT THE SOFTWARE AND HARDWARE INSTRUMENT “KRUIZ” BASISKuzhil A.S., Padun S.P., Bykov A.V. Innovative firm SNIIP Atom LLCABSTRACTSoftware and hardware instrument “Kruiz” was developed by our firm at the end of 1990-s. Their last versions are currently implemented at Russian, Ukrainian and EU (Mochovce) NPP. Over time the great scope of verification and validation of core monitoring system (CMS) software was done. Due to the new regulation requirements certification of calculating kernel of CMS “Kruiz” software in Russian nuclear regulator is held. Verification peculiarities of some kernel calculation components are presented at the report. Comparison examples with certified codes and Russian and abroad NPP operation measured data are presented. Ability of further software and hardware instrument “Kruiz” development for the PWR core monitoring was shown. To date our “Kruiz” CMS software has reference operation experience on WWER reactors more than 250 reactor-years.26th Symposium of AER on VVER Reactor Physics and Reactor Safety 29 10 – 14 October 2016, Helsinki, Finland
