HIGH LEVEL RADIOACTIVE WASTE GEOLOGICAL DISPOSAL EQUIPMENT AND GEOLOGICAL DISPOSAL METHOD

摘要

PROBLEM TO BE SOLVED: To provide geological disposal equipment having a further enhanced confinement performance by housing and sealing high level radioactive waste such as glass-solidified matter and inhibiting corrosion of a geological disposal container subjected to geological disposal, and also to provide a geological disposal method.;SOLUTION: The geological disposal equipment 1 for high level radioactive waste comprises: the geological disposal container 10 primarily composed of a metal-made container body 11 for housing and sealing the high level radioactive waste; a buffer material container 20 covering the whole surface of the geological disposal container; and corrosion-inhibiting means 13a and 13b for electrochemically inhibiting corrosion on the surface of the container body by applying a potential difference between the container body and the buffer material container.;COPYRIGHT: (C)2006,JPO&NCIPI
