PROBLEM TO BE SOLVED: To reduce the quantity of steel materials required to store canisters. SOLUTION: A pair of storage rooms 2 are placed in the right and left positions in a storage building 1 composed of shielding walls made of thick reinforced concrete. An air inlet 3 is placed in the lower part of the outside wall at the right and left of the storage rooms 2 to allow the air inlet to communicate with an outside air intake 4 placed on the sidewall 1a of the storage building 1. An air outlet 5 is placed in the center in the width direction of a ceiling wall 1b of the storage building 1 and is connected with the lower end of the outlet shaft 6 with an exhaust port 7 at its upper end. The canisters 8 are sealed and accommodated in storage containers 9 made of carbon steel and each storage container 9 as a whole is stored in the storage rooms 2. The heat release from the canisters is conducted to the air in the storage rooms 2 by way of the storage containers 9. The air in the storage rooms 2 is naturally ventilated by the draft force based on the differential pressure between the air whose temperature is raised by the heat release from the canisters 8 and which is released through the air outlet 5, the outlet shaft 6 and the exhaust port 7 and the low-temperature air flowing in through the outside air intake 4 and the air inlet 3 to continuously cool the storage containers 9 accommodating the canisters 8.
