COMPARISON OF CALCULATED AND MEASURED FA RELATIVE POWERS AT KOLA NPP UNITS 3 AND 4
17th Symposium of AER on VVER Reactor Physics and Reactor Safety (2007, Yalta, Crimea (Ukraine, back then))
CORE OPERATION, EXPERIMENTS AND CODE VALIDATION
Abstract
It is discussed the results of investigations on comparison of the calculated and measured FAs relative power distribution based on thermocouples data in the VVER-440 cores. All main results were obtained during 5 last years in the RRC ?Kurchatov Institute? and are based on the measurements and calculations which have been performed for the 3-d and 4-th units of the Kola NPP. Fuel loadings of various compositions were analyzed for various cycle moments. In all, about 1200 core conditions were studied.
