Example of a spent fuel pool from the shut-down Caorso Nuclear Power Plant. This pool is not holding large amounts of material. 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 ...
The Russian dry storage facility for spent nuclear fuel, the HOT-2 at Mining Chemical Combine in Zheleznogorsk, Krasnoyarsk Krai in Siberia, is not a 'cask' facility per se, as it is designed to accommodate the spent nuclear fuel (both VVER and RBMK) in a series of compartments. The structure of the facility is made up of monolithic reinforced ...
Spent nuclear fuel stays a radiation hazard for extended periods of time with half-lifes as high as 24,000 years. For example 10 years after removal from a reactor, the surface dose rate for a typical spent fuel assembly still exceeds 10,000 rem/hour—far greater than the fatal whole-body dose for humans of about 500 rem received all at once.

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.
Indian Point began dry cask storage of spent fuel rods in 2008, which is a safe and environmentally sound option according to the Nuclear Regulatory Commission. [89] Some rods have already been moved to casks from the spent fuel pools. The pools will be kept nearly full of spent fuel, leaving enough space to allow emptying the reactor ...
When spent nuclear fuel is separated it into its component parts, one of the products is plutonium. Successive governments have kept the material to leave open the option to recycle it into new ...
The first step is to cease operations and stow any spent fuel or waste. Nuclear reactors produce high-level waste in the form of spent nuclear fuel, which continues to release decay heat due to its powerful radioactivity. Storing this waste underwater in a spent fuel pool prevents damage and safely absorbs the radiation. Over a period of years ...
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.
