摘要： PROBLEM TO BE SOLVED: To provide a canister for accommodating radioactive substances which makes it possible both to lay out neutron shields more easily than conventional canisters for accommodating radioactive substances and to further improve the neutron shielding performance. SOLUTION: The canister C for accommodating radioactive substances in this invention is equipped with a main body 1 of the canister C for accommodating the radioactive substances and a can 2 filled with the neutron shields 4, formed separately from the main body 1 of the canister C and mounted on its bottom by non-welding. In the canister C for accommodating radioactive substances, the can 2 filled with the neutron shields 4 is post-mounted on the main body 1 of the canister C not by welding, which prevents the neutron shields 4 from degenerating due to heat and makes it possible to lay out them at the bottom without turning over the top and bottom.

摘要： PROBLEM TO BE SOLVED: To shorten the production period of a cask for spent fuel transporta tion and storage and uniformalize the radiation shield capability in the axial direction of the cask for spent fuel. SOLUTION: A mixture of epoxy resin, powder neutron absorber and refractory material is injected in a laid metal mold 20 (step 14). Then, a work of primary hardening is conducted (step 15). The primary hardening is attained by heating the metal mold 20 injected with the mixture in a furnace. During the primary hardening, the viscosity of the resin in the mixture 22 in the metal mold 20 temporarily lowers and the neutron absorber and the refractory material uniformly deposit neat the bottom plate 22 of the metal mold 20. After the primary hardening, secondary hardening is conducted (step 16). A neutron shield body 5 taken out of the metal mold 20 (step 17), is attached on the outside of the inner cylinder 2 of the cask 1 for spent fuel (step 18). COPYRIGHT: (C)2004,JPO
