Study on the Monitoring Technology of Fuel Cladding Damage in a Nuclear Power Plant
Fuel cladding damage monitoring is an important means to evaluate the integrity of the first barrier and ensure the safety operation of power plants.The monitoring equipment is bulky and the monitoring methods have some shortcomings in nuclear power plants,such as false alarms.Aiming at the problem for the real alarm of non-fuel cladding damage caused by the design defects of the fuel cladding damage monitoring method and the alarm control logic in a nuclear power plant,a gamma coupled fuel cladding damage monitoring method is proposed,and the alarm control logic is optimized and the alarm signal delay measures are implemented to fundamentally eliminate the false alarm problem of fuel cladding damage monitoring in a nuclear power plant.
