GLASS SOLIDIFIED BODY STORING FACILITY

摘要

PROBLEM TO BE SOLVED: To prevent leakage of primary radiation while securing flow of cooling air in a cell room. SOLUTION: In a glass solidified body storing facility in which glass solidified bodies 1 are stored in the cell room 3 and the cooling air 12 is made to flow, two radiation shielding plates 19 having a desired number of through holes 20 with shifted phases are arranged with a desired interval in the flowing direction of the cooling air 12 in an inlet 13 and an outlet 14 of the cooling air in the cell room 3. The radiation shielding plates 19 have a sandwich structure of two front and back iron plates for attenuatingγrays and a polyethylene plate for attenuating neutron rays.
