安全性を維持することができるようにされている。When this liquid sodium comes into contact with an atmosphere containing oxygen or water, concrete, etc., it rapidly reacts and burns, but reactor buildings that house nuclear reactors that use such liquid sodium as a coolant are generally made of concrete. Therefore, in conventional reactor buildings, a liner made of stainless steel or the like is installed on the inside of the reactor building, where there is a possibility that a liquid sodium leakage accident could occur and the liquid sodium would come into contact with concrete. Even if this occurs, contact between liquid sodium and concrete can be prevented to maintain the integrity and safety of the reactor building.

The floor of the reactor building 2 that houses this coolant distribution pipe 1 is coated with aluminum oxide (AJ2zO3) of 50 to 80% on the top surface of the concrete floor 3.
A sodium-resistant layer 4 made of sodium-resistant concrete with about 0% sodium content is formed, and a plurality of narrow grooves 5 are formed in this sodium-resistant layer 4 to store leaked liquid sodium. Further, on the concrete surface 6 of the side wall and the concrete surface 7 of the ceiling of this reactor building 2, a sodium-resistant layer 8.9 made of sodium-based concrete is formed, which has the same resistance as the floor surface.

Even if liquid sodium scatters on the inner surface of the reactor building 2, the sodium-resistant layer made of sodium-resistant concrete 4.
6.7, no rapid reaction between liquid sodium and sodium-resistant concrete occurs, and the integrity of the reactor building is maintained. In addition, if liquid sodium leaks to people, the liquid sodium will be stored in the narrow grooves 5 formed in the sodium-resistant layer 4 on the floor, and the liquid sodium will be mixed with an atmosphere containing oxygen or water. Since the contact area is reduced, rapid reactions between liquid sodium and an atmosphere containing oxygen or water are also suppressed, and the integrity of the inside of the reactor building is maintained.
