A fuel pool cooling device that provides a heat exchanger in the middle of a fuel pool water circulation system of a nuclear power generation facility and cools the fuel pool water by supplying cooling water to the heat exchanger. A fuel pool cooling device characterized in that an auxiliary cooling device using refrigerator chiller water is provided on the cooling water supply side of a heat exchanger and is activated when the cooling load of the fuel pool water exceeds a set value. 2 The auxiliary cooling system includes a backup heat exchanger that cools the reactor auxiliary cooling water with refrigerator chiller water, and a back-up heat exchanger that cools the reactor auxiliary cooling water using the chiller water, and converts the reactor auxiliary cooling water cooled by this heat exchanger into the heat for cooling the fuel pool water. Utility model registration claim 1 comprising a line supplying the exchanger
Fuel pool cooling device as described in Section 2. 3. The fuel pool cooling device according to claim 1, wherein the auxiliary cooling device is a fuel pool cooling device, in which a refrigerator chiller water pipe is connected to a heat exchanger for cooling the fuel pool water via an on-off valve. 4. The fuel pool cooling system according to claim 1, wherein the refrigerator chiller water is for an air conditioner system in a building installed in a nuclear power generation facility.
