Fuel storage facility, remodeling method for fuel storage facility, and reactor building

摘要

To provide a fuel storage technique capable of reducing vibration of a nuclear-fuel storage rack at the time of an earthquake.SOLUTION: A fuel storage facility comprises at least two racks of a first rack 7A and a second rack 7B for storing nuclear fuel such that the racks 7A, 7B are arranged side by side in water in a storage pool 2, and a specified member 11 arranged therebetween. The specified member 11 has a first surface 13 facing to an outer surface 12 of the first rack 7A, and a second surface 14 facing to an outer surface 12 of the second rack 7B with a space held between the first surface 13 and the second surface 14. A gap G is formed to allow water flow at least between the first rack 7A and the first surface 13, or the second rack 7B and the second surface 14.SELECTED DRAWING: Figure 3
