Santa Clara, Calif.–based Oklo is planning to build its second and third commercial Aurora Powerhouse nuclear plants in southern Ohio, the company announced yesterday. The advanced reactor developer received a site permit in December 2019 from the Department of Energy to build its initial Aurora facility at Idaho National Laboratory.

According to the announcement, Oklo has signed an agreement with the Southern Ohio Diversification Initiative (SODI), a community-reuse organization, to deploy two 15-MWe plants on land owned by SODI at the Portsmouth site near Piketon, Ohio. The DOE began transferring parcels of the Portsmouth site—home to the Portsmouth Gaseous Diffusion Plant, now undergoing decontamination and decommissioning—to SODI in June 2018 for economic development.

Workers at the Department of Energy’s Portsmouth Site in Ohio have been using a new tool as part of the dust-suppression systems for the X-326 process building demolition project. The X-326 was one of three massive process buildings originally built to enrich uranium at the site, which was in operation starting in the 1950s. Environmental remediation of the site began in 1989, and deactivation and decommissioning activities began in 2011. Demolition of the facility has led to a dusty work environment.
