When Constellation decided to install replacement Alstom low-pressure turbines at three of its boiling water reactor plants more than 15 years ago, one benefit was knowing the new turbines should operate reliably—and without major inspections—for several years.

Five companies are the recipients of Department of Energy awards to support the development, modification, and licensing of transportation packages for high-assay low-enriched uranium (HALEU) fuel. HALEU, which is enriched between 5 percent and 20 percent, is the type of fuel required for the operation of many of the small advanced nuclear reactors that are being designed and developed by U.S. companies.

Holtec International announced that it has been awarded a turnkey supply contract by Taiwan Power Company (TPC) to establish indoor dry spent nuclear fuel storage facilities at both the closed Chinshan and Kuosheng nuclear power plant sites on the island nation.
A WTP crew vitrified the first Hanford Site tank waste inside one of two melters in the Low-Activity Waste Facility. Top right, a camera inside the melter’s pour cave shows the vitrified waste being poured into a stainless steel container as well as the hot liquid inside the container. Bottom right, the first two containers filled with vitrified waste in the pour cave prior to being lidded, swabbed to verify their exteriors are free of contamination, and then moved into the export bay.

The Department of Energy has announced that the Hanford Site’s Waste Treatment and Immobilization Plant (WTP) has reached a commissioning milestone, producing more than 20 stainless steel containers of immobilized low-activity radioactive waste.

Longenecker & Associates has announced a $500,000 pledge from John and Bonnie Longenecker to the National Atomic Testing Museum in Las Vegas, Nev. The contribution will strengthen the museum’s missions to inform the public about America’s national security legacy and current programs and to inspire students, educators, and young professionals pursuing careers in science, technology, engineering, and mathematics.

France’s Nuclear Safety and Radiation Protection Authority (ASNR) completed its technical review and issued a satisfactory opinion on Andra’s license application to construct the Cigéo deep geological disposal facility. Andra is the French national agency responsible for the safe management of all radioactive waste in the country.

A 3D-printed tool has been developed at the Department of Energy’s Savannah River Site in South Carolina that can eliminate months from the job of radioactive tank waste sampling.

U.K.-based Perpetual Atomics and U.S.-based QSA Global claim to have achieved a major step forward in processing americium dioxide to fuel radioisotope power systems used in space missions. Using an industrially scalable process, the companies said they have turned americium into stable, large-scale ceramic pellets that can be directly integrated into sealed sources for radioisotope power systems, including radioisotope heater units (RHUs) and radioisotope thermoelectric generators (RTGs).

Idaho National Laboratory has announced the creation of the first batch of enriched uranium chloride fuel salt for the Molten Chloride Reactor Experiment (MCRE). INL said that its fuel production team delivered the first fuel salt batch at the end of September, and it intends to produce four additional batches by March 2026. MCRE will require a total of 72–75 batches of fuel salt for the reactor to go critical.
