Spent fuel pools (SFP) are storage pools (or "ponds" in the United Kingdom) for spent fuel from nuclear reactors. They are typically 40 or more feet (12 m) deep, with the bottom 14 feet (4.3 m) equipped with storage racks designed to hold fuel assemblies removed from reactors.
Spent fuel pool at TEPCO's Fukushima Daiichi Nuclear Power Plant on 27 November 2013. Spent nuclear fuel is stored either in spent fuel pools (SFPs) or in dry casks. In the United States, SFPs and casks containing spent fuel are located either directly on nuclear power plant sites or on Independent Spent Fuel Storage Installations (ISFSIs).
Units 1 through 4 at the plant. At the time of the earthquake, Unit 4 had been shut down for shroud replacement and refueling since 29 November 2010. [1] [2] All 548 fuel assemblies had been transferred in December 2010 from the reactor to the spent fuel pool on an upper floor of the reactor building [3] where they were held in racks containing boron to damp down any nuclear reaction.

Nuclear experts have warned of the risk of damage to the plant's spent nuclear fuel pools or its reactors. Cuts in power needed to cool the pools could cause a disastrous meltdown.
Some water is recycled to cool the nuclear fuel, while the rest is stored in the tanks. ... Spent fuel removal from the Unit 1 reactor's cooling pool is set to start in 2027. The reactor top is ...
In the late 1970s and early 1980s, the need for alternative storage in the United States began to grow when cooling pools at many nuclear reactors began to fill with stored spent fuel. As there was not a national nuclear storage facility in operation at the time, utilities began looking at options for storing spent fuel. Dry cask storage was ...
Kansai Electric, Japan's largest nuclear plant operator, is urgently seeking additional storage for spent fuel: the cooling pools at its plants are more than 80% full.
It is owned by GE Hitachi Nuclear Energy and located near the city of Morris. [2] The site is located immediately southwest of Dresden Generating Station. Spent nuclear fuel assemblies are stored at this away-from-reactor, Independent Spent Fuel Storage Installation (ISFSI) in a spent fuel storage pool.
