| Outline of Final Research Achievements |
In the reactor, the uranium fuel is consumed, and plutonium is generated. The development study of the reactor neutrino detector that was able to monitor a dangerous plutonium content was done with Gd containing new plastic scintillator. The performance of the prototype detector of 82kg was evaluated by using the gamma ray and the neutron from Am241/Be source as a pseudo neutrino signal. The performance of the reactor monitor of one ton was evaluated by the Geant4 simulation based on the obtained experimental data. The result that taking out the fuel of 6% (equivalent plutonium 90kg) was able to be confirmed by the significance of 2σ in the measurement of 11 days was obtained for the reactor of thermal power 3GW for the change in the plutonium content at the before and after of the refueling.
