METHOD FOR EVALUATING CORROSION IN USED-NUCLEAR FUEL STORAGE CONTAINER, AND TESTING APPARATUS AND SPECIMEN FOR EXPERIMENT THEREFOR

摘要

The present invention provides a testing apparatus for evaluating corrosion in a used-nuclear fuel storage container, comprising: a jig arranged within a space where a corrosion experiment is held and supporting at least one specimen for the experiment; a voltage detecting portion electrically connected to the specimen provided in the jig, applying current of a certain value to the specimen, and detecting a voltage change amount; and a calculation portion connected to the voltage detecting portion and converting a voltage value detected from the voltage detecting portion into actual corrosion years, thereby capable of accurately evaluating the actual corrosion years in accordance with a level of corrosion of the used-nuclear fuel storage container.;COPYRIGHT KIPO 2018
