Here is a recap of industry happenings from the recent past:
Centrus-Oklo partnership expands
Oklo, a California-based developer of next-generation fission reactors, has expanded its partnership with Centrus Energy, a Maryland-based supplier of nuclear fuel and services. The two companies have been cooperating since 2021 on the development of Centrus’s American Centrifuge Plant in Piketon, Ohio, to produce high-assay low-enriched uranium (HALEU) fuel. According to the companies’ new memorandum of understanding, Centrus will manufacture certain components for Oklo’s Aurora “powerhouse” reactor, a fast neutron reactor designed to generate up to 15 MW of power and operate for at least 10 years without refueling. The Aurora is also designed to produce usable heat. Centrus also has agreed to purchase electricity generated by the Aurora reactors, while Oklo has agreed to purchase HALEU fuel from the Piketon facility. The facility is expected to begin fuel production before the end of the year.

A disk tubular reverse osmosis (DTRO) membrane system was designed and applied for the treatment of radioactive wastewater produced in a high-temperature gas-cooled reactor (HTGR) in pilot scale. The pretreatment system was simplified using a cartridge filter. A three-stage membrane system was researched and developed. The performance of the DTRO system was examined using surrogate wastewater. The volume reduction factor of the system reached 50, and the decontamination factor reached 5760. The membrane system was designed to operate at high flows. When wastewater was pumped into the membrane system, the high-speed flow of the influent prevented the fouling of the membrane. The operational performance to treat low- and intermediate-level radioactive wastewater was examined. The membrane system can be used to treat the wastewater from HTGR.
