。11. As shown in Fig. 4, since the above structure is as shown in Fig. 4, the heat transferred from the canister 0 to the building concrete frame A as radiant heat and convection heat transfer is blocked by the heat shielding wall and the cooling air. When the radiation reaches the heat shield wall, it generates heat within the heat shield wall and does not reach the concrete frame of the building.

きる。With the above configuration, as shown in FIG. 4, radiant heat and convection heat transfer from the canister C to the building concrete frame A are blocked by the heat shielding wall 8 and the inflow of cooling air, and,
The radiation from the canister O generates heat within the heat shielding wall 8 and does not reach the building body A, thereby preventing the temperature of the building body from rising. At this time, the heat shielding wall 8 will undergo thermal expansion, but the expansion can be escaped by extending downward and by extending the combined portion.
