摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-performance container for the treatment of medium and low level radioactive waste in a nuclear power plant using steel fiber reinforced polymer impregnated concrete (SFPIC).;The present invention is to propose a basic specification of a high-integrity container to be developed in manufacturing a high-integrity container using the SFPIC, and to provide a method for producing an SFPIC having a minimum target strength of 1,000 kg / cm 2, which is the main material to be used for manufacturing the container. We propose a high-integrity container manufactured using the developed SFPIC, and test the chemical resistance and drop impact for evaluating the physical properties of the materials used and the performance of the real container in order to prove the service life of more than 300 years. About 20 kinds of proof tests such as irradiation test and irradiation. According to the manufacturing method of the high-integrity container using the SFPIC of the present invention, it is possible to improve the reliability of radioactive material management by establishing the basis for localization and standardization of the high-intelligent container as well as securing the safety and soundness of radioactive waste treatment. And it can be used as a special industrial waste treatment machine.
