Abstract

The invention discloses a nuclear fuel irradiation test method, and belongs to the technical field of research on reactor fuel irradiation. The nuclear fuel irradiation test method comprises the following steps: packaging fuel, wherein filling the fuel into pre-processed and installed and welded fuel assemblies each with a one-way opening, arranging each a pair of the assemblies to be one group between clamping block assemblies side by side; conveying a test section into a reactor, wherein hoisting the test section in the reactor from the reactor top, irradiating the test section to be at a reactor core active section, and connecting a irradiation device section with the reactor top through a flange in sealed connection; carrying out in-reactor test, wherein testing and monitoring relatedparameters after the fuel enters the reactor along with the irradiation device; and discharging the test section out of the reactor, wherein discharging the fuel after a irradiation neutron fluence specified by the test is reached through irradiation. The nuclear fuel irradiation test method is invented aiming at the irradiation requirement of novel nuclear fuel in reactors; the nuclear fuel irradiation test method is more economical and reliable, can reflect the irradiation condition of the nuclear fuel in the reactor in real time, and accurately obtain related irradiation parameters.

Description

technical field [0001] The invention relates to the technical field of research reactor fuel irradiation, in particular to a nuclear fuel irradiation test method. Background technique [0002] As the nuclear power industry enters a new period of development, the number of nuclear power projects in operation, under construction and planned to start nationwide increases year by year, and the proportion of nuclear energy in energy consumption continues to increase, prompting the acceleration of nuclear power replacement. At the same time, the development and research of a new generation of nuclear power plants has a greater need and higher requirements for new nuclear materials and nuclear fuels, especially for more economical, safer, and high-burnup nuclear fuels. In the process of research and development of new nuclear fuel, it must be irradiated in the reactor. After the irradiation in the reactor reaches the target fluence, the post-irradiation inspection method is used to...
