Measurement of the Power Output of the VVER-1000 Reactor Based on the Antineutrino Flux from the Core

Abstract

The results of measuring the power output of an industrial nuclear reactor based on the antineutrino flux from the core are presented. The measurements were conducted using the iDREAM detector at a distance of 19.5 m from the center of the core of the VVER-1000 reactor at Unit 3 of the Kalinin Nuclear Power Plant. Estimates of the sensitivity of the iDREAM detector to changes in reactor power over 2-, 4-, and 6-h intervals of antineutrino interaction statistics collection were obtained.
