Monitoring Akkuyu nuclear reactor using antineutrino flux measurement

Abstract

We present a simulation-based study for monitoring Akkuyu nuclear power plant's activity using antineutrino flux originating from the reactor core. A gadolinium-doped water Cherenkov detector was designed and optimization studies were performed using the Geant4 simulation toolkit. It was found that the bottom (or top) face of the target should be instrumented by six 10-inch-diameter photomultiplier tubes with photon detection efficiency of about 35% and the optimum Gd concentration was found to be about 0.3%-0.5%. The first study on the design of a monitoring detector facility for Akkuyu nuclear power plant is discussed in this paper.
