Texas universities evaluating SMRs for water desalination

Natura Resources has signed a memorandum of understanding with two Texas universities—Texas Tech University and Abilene Christian University—to evaluate the integration of the company’s molten salt small modular reactor technology with water desalination systems. The collaboration includes Texas Tech’s Texas Produced Water Consortium, which was established by the Texas legislature in 2021 to explore the potential benefits of using treated produced water for purposes outside of the oil and gas industry of the Permian Basin. Produced water is salty or brackish hydrocarbon-containing water that is produced as a byproduct of oil and gas extraction. The stated goal of the new collaboration is to develop “a sustainable solution for water scarcity by purifying produced water from oil and gas operations, making it available for agricultural and other beneficial uses.” Abilene Christian University is planning to host the first deployment of Natura Resources’ Natura MSR-1, a 1-MWt molten salt research reactor.

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.

TerraPower signs contracts to advance Natrium

TerraPower and Centrus Energy have signed a memorandum of understanding to expand their collaboration in the development of commercial-scale production of high-assay low-enriched uranium (HALEU) to fuel TerraPower’s Natrium sodium-cooled fast reactor, which is designed with a molten salt–based energy storage system. TerraPower is planning its Natrium demonstration project for a site in Kemmerer, Wyo., with a target operational date of 2030. Centrus plans to produce as much as 20 kilograms of fuel by the end of 2023 at its production facility in Piketon, Ohio, and to further scale up production with additional centrifugal cascades.

International SMR collaboration launched

The nine member states of the International Nuclear Regulators’ Association (INRA)—Canada, France, Germany, Japan, South Korea, Spain, Sweden, the United Kingdom, and the United States—have agreed to collaborate on the generic design assessment and licensing of small modular reactor technologies. According to a statement released by the organization, the internationally standardized reactor designs would aid in the facilitation of efficient regulatory reviews, although local issues such as siting and environmental factors must be addressed by national regulatory agencies. The INRA members expressed their support for the International Atomic Energy Agency’s Nuclear Harmonisation and Standards Initiative, but they stressed that independent, national regulatory reviews should not be replaced by an international approach.
