The RENO experiment is to measure the unknown neutrino mixing angle θ
13by using anti- neutrinos emitted from the Yonggwang nuclear power plant in Korea. A mock-up detector was made to test the mechanical structure and the optical properties of the detector before the construction of the RENO detector. In this research, we performed a Monte Carlo simulation of a mock-up based on the Geant4 simulation package. We compare the mock-up distribution of energy deposited, the quenched energy deposited, the absorption and the emission of photons, the number of photons arriving at photomultiplier tube with the results for the RENO detector.
