Simulation of Antineutrino Detection Based on Plastic Scintillator Detector Array

摘要

Most of the commercial reactors currently in operation are pressurized water reactors.The four nuclides of 235U,238U,239Pu,and 241Pu inside the core will produce anti-electron neutrinos when the unstable products formed in the fission process undergoβdecay.The number and energy spectrum of anti-neutrinos released by the reactor will change,along with the operating power of the reactor and the contribution of nuclides in the core.Therefore,anti-neutrino monitoring technology is an important means of nuclear monitoring and security.
