Spent nuclear fuel, occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant). It is no longer useful in sustaining a nuclear reaction in an ordinary thermal reactor and, depending on its point along the nuclear fuel cycle , it will have different isotopic ...
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 ...
The Nuclear Waste Policy Act of 1982 established a timetable and procedure for constructing a permanent, underground repository for high-level radioactive waste by the mid-1990s, and provided for some temporary storage of waste, including spent fuel from 104 civilian nuclear reactors that produce about 19.4% of electricity there.

The states that ratify the Convention agree to be governed by the convention's provisions on the storage of nuclear waste, including transport and the location, design, and operation of storage facilities. [citation needed] The Convention implements meetings of the state parties that review the states' implementation of the convention.
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 advanced reprocessing of spent nuclear fuel is a potential key to achieve a sustainable nuclear fuel cycle and to tackle the heavy burden of nuclear waste management. In particular, the development of such advanced reprocessing systems may save natural resources, reduce waste inventory and enhance the public acceptance of nuclear energy.
The back-end of the nuclear fuel cycle, mostly spent fuel rods, contains fission products that emit beta and gamma radiation, and actinides that emit alpha particles, such as uranium-234 (half-life 245 thousand years), neptunium-237 (2.144 million years), plutonium-238 (87.7 years) and americium-241 (432 years), and even sometimes some neutron ...
KBS-3 is also to be used in Finland at the Onkalo spent nuclear fuel repository, being built by Posiva. The disposal method consists of the following steps: [1] The waste is first stored in intermediate storage for 30 years. The waste is encapsulated in cast iron canisters. The cast iron canisters are encapsulated in copper (CuOFP alloy) capsules.
