摘要：

A primary failure mechanism of reactor pressure vessel (RPV) steel is the embrittlement caused by fast-neutron irradiation. In this work, neutron irradiation tests were performed on an RPV steel at a high temperature (292 degrees C) using a neutron irradiation test reactor. In addition, its magnetic properties were measured before and after irradiation in a hot laboratory. These measurements show that (i) the clockwise variation of the magnetisation for the hysteresis loops of RPV steel before irradiation was lower than that after it; (ii) sample magnetisation before and after irradiation was not sensitive to changes in temperature, with only a very small hysteresis effect; and (iii) when irradiation damage did not exceed 0.154 dpa, the residual magnetisation intensity of the RPV steel was linear to the radiation fluence, and the initial magnetic susceptibility exhibited an exponential relationship with the radiation fluence. Finally, the magnetic properties of the RPV steel can be used to characterise the degree of its irradiation-induced embrittlement, and measurements of magnetic properties can be used for nondestructive evaluation in monitoring the degree of irradiation damage experienced by in-service RPV steel.
