Round Up: Centrus to join S&P SmallCap 600 Index; Moul joins Standard Nuclear’s board

By ExchangeMonitor

Centrus Energy will join the S&P SmallCap 600 Index before markets open July 14, a move the company said reflects its growing role in rebuilding the U.S. nuclear fuel supply chain and expanding domestic uranium enrichment capacity.

“Our invitation into the S&P SmallCap 600 reflects the progress our team has made and the expanding role that Centrus will play in fueling the future of nuclear energy,” President and CEO Amir Vexler said in a statement Tuesday.

The move comes as Centrus advances an expansion of its uranium enrichment operations in Piketon, Ohio, the release said. The company launched domestic centrifuge manufacturing late last year to support the planned expansion, which is intended to increase production of low-enriched uranium, high-assay low-enriched uranium for advanced reactors, and enriched uranium for national security missions. Centrus has said the multibillion-dollar project could create thousands of jobs and rank among the nation’s largest nuclear infrastructure projects.

Former Tennessee Valley Authority (TVA) President and CEO Don Moul joined Oak Ridge, Tenn.-based Standard Nuclear’s board of directors as an independent director this week.

Moul stepped  down from his role at TVA on July 1, having one of the shortest tenures as the CEO of the federally owned utility serving around one year. Moul has over 40 years of experience in the nuclear industry and has held other high-level management roles. The company said in a Monday press release the appointment of Moul shows its strategic focus on “on building durable operational expertise into its leadership structure.”

“Don Moul has spent his career operating and scaling nuclear infrastructure at the highest levels of the American power sector,” Kurt Terrani, Standard Nuclear CEO, said in the release. “His decades of proven operational leadership and hands-on experience will be invaluable as we look to scale our infrastructure and expand Standard Nuclear’s national footprint.”
