In 2015, Posiva received a construction license from the Finnish government for the repository, which will be constructed to a depth of 1,300 to 1,500 feet.

The year 2024 is shaping up to be a historic one for Posiva, the waste management organization owned by Finland’s two nuclear power plant utilities, Fortum and Teollisuuden Voima. The company is looking to receive regulatory approval of its operating license for the Onkalo deep geological repository for high-level radioactive waste by the end of the year.

Holtec International announced on December 19 that Energoatom, Ukraine’s national nuclear energy company, has begun transporting spent nuclear fuel from the nation’s operating reactors to its newly built and commissioned Central Spent Fuel Storage Facility (CSFSF). The facility is expected to save Ukraine $200 million annually through avoided payment to the Russian Federation for transport and storage to that country.

According to a December 15 report by Interfax, a total of 13 spent fuel containers have already been placed at the CSFSF, which is currently operating under a three-year trial operation permit.

Background: Located inside the Chernobyl Exclusion Zone, the CSFSF is designed for the long-term storage of spent nuclear fuel from the South Ukraine, Khmelnytskyi, and Rivne nuclear power plants.

Holtec, under contract by Energoatom, completed the construction and licensing of the CSFSF in 2021. Transport of spent fuel to the facility was to begin in early 2022 but was delayed by Russia’s invasion of Ukraine.

Holtec International announced that it successfully loaded its 2,000th spent nuclear fuel canister this fall as part of the ongoing dry storage campaign at Entergy’s Arkansas Nuclear One (ANO) power plant in Russellville, Ark.

Spent fuel from ANO’s two pressurized water reactors is stored in Holtec’s MPC-37 multipurpose canister, each containing 37 PWR fuel assemblies in a prismatic basket made of Holtec’s Metamic-HT material in an egg-crate configuration. The company’s HI-STORM dry fuel storage systems have been in use at ANO since 2003.

Quote: Entergy’s chief nuclear officer, Kimberly Cook-Nelson, said, “We appreciate the strong partnership that we at Entergy have with Holtec. Arkansas Nuclear One is an important facility for our company, the industry, the state of Arkansas, and the Russellville community, and having the 2,000th spent fuel dry storage system is a key milestone for our continued safe, secure, and reliable operations.”
