PLUG TYPE RESEARCH REACTOR IRRADIATION TEST RIG

摘要

An irradiation test rig, which prevents the irradiation test rig from directly contacting the weakly side wall of the irradiation hole such as the irradiation hole side wall of the research reactor, and which is mounted and fixed in a plug type fashion on the lower end spider cup and the top--end plate, and thus protects the irradiation hole wall of the research reactor, so that reactor core integrity is secured and safety is improved, is disclosed. The present invention provides an art whereby the specimen capsule can be charged on the side of the test assembly since charging the specimen capsule in the irradiation test rig is in the form of the existing combined assembly. In addition, the present invention enables the reuse of the irradiation test rig and the reuse of the assembly for charging the specimen capsule, so it provides an art whereby it is possible to charge and test specimen capsules that require different test periods in the same rig by utilizing the incidental effect of reducing radioactive waste and the easiness of dismantlement and assembly, and an art of irradiation test rig whereby various tests are possible such as monitoring the change through intermediate checking of specimen capsules by taking out the rig from the research reactor.
