Abstract

Abstract

This paper presents the diagnosis physical model based on quantitative analysis and the design of online monitoring device for the fuel cladding defect in PWR operation conditions. A complete solution for online monitoring of fuel defect is given. Meanwhile, the correctness of the system design is verified by measurement data and theoretical simulation, and the radiation source experiment for prototype as well, to solve the deficiencies of the existing means of fuel defect monitoring in CPR1000 units, and to improve the safety performance of pressurized water nuclear power unit operation.
