Representativeness Analysis of the Readings of the Coolant Temperature Control Channels at the Inlet and Outlet of the VVER-1200 Core of the First Power Unit of Novovoronezh NPP-2

The generalized results of an analysis of the readings of the coolant temperature control channels of the in-core control system (ICMS) at the inlet and outlet of the VVER-1200 core of Novovoronezh NPP-2, No. 1 are presented. The data were obtained in field tests and verification of the ICMS during...

description The generalized results of an analysis of the readings of the coolant temperature control channels of the in-core control system (ICMS) at the inlet and outlet of the VVER-1200 core of Novovoronezh NPP-2, No. 1 are presented. The data were obtained in field tests and verification of the ICMS during the commissioning of the power unit as well as during its operation in the first two runs. The factors influencing the readings, associated with the design features of the in-vessel devices, the location of the in-core sensors, and the features of the controlled neutronic and thermohydraulic processes, were determined. Suggestions for their accounting are given.
