Abstract
The results of tests of the mode related to switching on one main coolant pump (MCP) when the other three MCPs are in operation that are obtained during commissioning work at ?Kozloduy? NPP, Unit 6, Bulgaria, and given in specification OECD/NEA VVER-1000 (V1000 CT-1) were used for calculations using the coupled thermohydraulic computer codes that are applied in OKB ?Gidropress? and include models of spatial kinetics and inter-loop mixing in the reactor.
