Abstract

The invention discloses a radiation supervision device for a core container of a high-flux research reactor, which comprises a lifting ring (1), a sample supporting body (2) and a bottom grid plate (3), and is characterized in that the inside of the sample supporting body (2) is provided with a small-sized CT sample, a tensile sample and a temperature monitor. The invention provides the radiation supervision device which is suitable for the core container of the research reactor and has a simple structure, small volume and reactor-following monitoring.

Description

technical field [0001] The invention relates to the technical field of radiation monitoring of research reactor core containers, in particular to a radiation monitoring device for high-flux research reactor core containers. Background technique [0002] The research reactor core vessel is an extremely critical part of the reactor body, and the core vessel is subject to strong thermal neutron radiation during reactor operation. The high-flux research reactor core vessel receives 10 23 (n / cm 2 ) neutron irradiation above the magnitude. The radiation damage of aluminum alloy caused by neutron irradiation and the transmutation of alloy elements lead to the change of material structure, resulting in the embrittlement of the core vessel material and the degradation of service performance. In order to ensure the safety of reactor operation and evaluate the service life of the core vessel, it is necessary to carry out on-site supervision of the irradiation performance of the core...
