FACILITY AND METHOD FOR STORING VITRIFIED WASTE

PROBLEM TO BE SOLVED: To provide a support structure suitable to jolts and impacts in an earthquake and thermal expansion differences, shorten the site installation processes of a large number of inner and outer tubes and a framework for supporting upper and lower outer tubes and also provide an appropriate vitrified waste storage facility where the precision in installation is improved in on-site assembly work. SOLUTION: The facility has a structure where a protruding earthquake-proof lug is placed on both inner and outer circumferential surfaces of the outer tubes, a reinforcing pad with a slit is mounted on the outer circumferential surface of the inner tubes connected to the lug and upper and lower earthquake-proof supports with slits are placed in positions connected to the upside of the framework for supporting the upper and lower outer tubes on the outer circumferential surfaces of the outer tubes. Moreover, the assembly and adjustment of the inner and outer tubes and the upper and lower earthquake-proof supports in a factory enable these assembled structures to be transported to a site and to be installed there as a single unit at a time.
