Upgrades to the particle accelerator enabling the record 1.7-MW beam operating power at the ORNL’s SNS included adding 28 high-power radio-frequency klystrons (red tubes) to provide higher power for the accelerator. (Photo: Genevieve Martin/ORNL)
The Spallation Neutron Source (SNS) at the Department of Energy's Oak Ridge National Laboratory set a world record when its particle accelerator beam operating power reached 1.7 MW, an improvement on the facility’s original design capability of 1.4 MW, ORNL announced on July 21. That higher power provides more neutrons for researchers who use the Office of Science user facility for materials science investigations.

“It is critical after the Hamaoka Nuclear Power Station restart that we reduce our cost and increase our capacity factor while becoming more economically competitive.” Ichiro Ihara, chief nuclear officer of Chubu Electric Power, made this observation recently when the Electric Power Research Institute visited the Japanese nuclear power plant for a strategy development session for plant modernization. EPRI’s team of five specialists spent four days at Hamaoka to investigate the feasibility of potential improvements—the third step of the EPRI modernization strategy planning process. It was a trip six months in the making—and the first time EPRI has applied its nuclear plant modernization process outside the United States.

The World Astatine Community (WAC) was formed earlier this year during the 12th International Symposium for Targeted Alpha Therapy by representatives from the United States, Japan, and the European Union to share astatine production technology and advance science and health care. The National Isotope Development Center (NIDC), which is managed by the Department of Energy’s Isotope Program (DOE-IP), announced the news on June 15 and explained how the United States plans to help expand the global supply of astatine-211.

Centrus Energy announced yesterday that it has received Nuclear Regulatory Commission approval to introduce uranium hexafluoride into its 16-machine centrifuge cascade in Piketon, Ohio, following operational readiness reviews by the NRC. Centrus says it “remains on track to begin production of high-assay low-enriched uranium (HALEU) by the end of 2023.” The announcement follows a series of inspections at the American Centrifuge site in April 2023.
