Abstract

PURPOSE: To eliminate the need for a remote dismantling device, reduce waste and lessen a disposal space by forming a radioactive waste cask with a structure in the reactor and a pressure vessel remaining stored without dismantling a biological shielding concrete. CONSTITUTION: After a peripheral 4, pipes and the like in the circumference of biological shielding concrete 3 are removed and a penetrated portion 5 connecting continuously the interior and exterior of the biological shielding concrete 3 is blocked, the circumference of the biological shielding concrete 3 and the concrete of a building 1 are removed, and subsequently the circumference of the shielding concrete 3 of the building 1 and one side wall and the roof are dismantled and removed. With a structure in the reactor and a pressure vessel 2 remaining stored, a radioactive waste cask A is formed by cutting the lower portion of the shielding concrete 3 and removing from the base of the body. Wheels 6 or the like are provided below the waste cask A for movement, and the cask is enclosed rightly in a concrete storage structure built underground.
