  2. Spent nuclear fuel - Wikipedia

    en.wikipedia.org/wiki/Spent_nuclear_fuel

    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 ...

  3. Dry cask storage - Wikipedia

    en.wikipedia.org/wiki/Dry_cask_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 ...

  4. Joint Convention on the Safety of Spent Fuel Management and ...

    en.wikipedia.org/wiki/Joint_Convention_on_the...

    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.

  5. High-level radioactive waste management - Wikipedia

    en.wikipedia.org/wiki/High-level_radioactive...

    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. [38]

  6. Nuclear flask - Wikipedia

    en.wikipedia.org/wiki/Nuclear_flask

    A nuclear flask is a shipping container that is used to transport active nuclear materials between nuclear power station and spent fuel reprocessing facilities. Each shipping container is designed to maintain its integrity under normal transportation conditions and during hypothetical accident conditions.

  7. Radioactive waste - Wikipedia

    en.wikipedia.org/wiki/Radioactive_waste

    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 ...

  8. KBS-3 - Wikipedia

    en.wikipedia.org/wiki/KBS-3

    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.

  9. Nuclear decommissioning - Wikipedia

    en.wikipedia.org/wiki/Nuclear_decommissioning

    Graphic of a dry storage of spent nuclear fuel. Radioactive waste that remains after the decommissioning is either moved to an on-site storage facility where it still is under control of the plant owner, or moved to a dry cask storage or disposal facility at another location. [9] The problem of long-term disposal of nuclear waste is still unsolved.
