Integrated 60Co and electron accelerator platform for irradiation effect and irradiation processing tests

Abstract

Irradiation technology has unique advantages and an invaluable role in nuclear energy, sterilization, and functional materials development. This paper introduces an integrated 60Co and electron accelerator platform for irradiation effect and irradiation processing tests at the Shanghai Institute of Applied Physics, Chinese Academy of Sciences. The 0.5 MeV electron irradiation experimental device can be used for the continuous processing of film and fiber samples, while the 1.5 MeV device can be mainly used for the intermittent irradiation testing of small products. This fills the domestic gap in the beta irradiation testing of third-generation nuclear power plants in China, which is of great significance in promoting the localization of nuclear power equipment. Both, columnar source and double plate source 60Co gamma irradiation test equipment have been developed, which are suitable for testing irregularly shaped samples. In addition, the irradiation-related detection equipment includes an electron paramagnetic resonance spectrometer and an alanine dosimeter, which can be used for free-radical detection, dose tracking, and the calibration of materials after irradiation.
