Latest on Zaporizhzhia: As of this morning, Russian military forces have taken control of the Zaporizhzhia nuclear power plant in Ukraine. The Russian military began shelling the Zaporizhzhia nuclear plant in southeastern Ukraine, resulting in a fire at the site on Thursday.
The American Nuclear Society calls on the world nuclear community to donate now to help Ukraine’s nuclear workers and their families impacted by war
The American Nuclear Society (ANS) has launched a humanitarian relief fund to help Ukraine’s nuclear professionals and their families impacted by the military invasion of their country.
An advanced nuclear reactor technology park is hoped for the 935-acre Clinch River site. Image: TVA
Last week’s announcement from the Tennessee Valley Authority about its “New Nuclear Program,” which outlines the potential development of the Clinch River site near Oak Ridge National Laboratory in Eastern Tennessee, is the catalyst for this week’s #ThrowbackThursday post. The Clinch River site was originally planned to be the location for the Clinch River Breeder Reactor, a project that, at the time, was meant to be the future of the nuclear industry in the United States.

The Department of Energy’s Office of Environmental Management (EM) announced on February 10 that it is set to deactivate and demolish the prototype for the reactor used for the USS Nautilus, the world’s first operational nuclear-powered submarine and the first submarine to complete a submerged transit of the North Pole.

The Department of Energy’s Office Nuclear Energy has launched a $6 billion program aimed at preserving the existing U.S. fleet of nuclear power reactors. Established under the Bipartisan Infrastructure Law, the Civil Nuclear Credit Program will allow owners and operators of commercial nuclear power reactors at economic risk of shutting down to apply for credits via a sealed bid process.

The ANS Fuel Cycle and Waste Management Division will present a webinar today at noon EST (the recording will be available via the webinar archive to all ANS members) featuring an international panel of experts on nuclear waste reprocessing. The panel will explore the idea of separating certain radionuclides from waste using recycling technology that enables pure materials to be used for other purposes.

A longstanding issue in boiling water reactors—shadow corrosion on zirconium alloy fuel rods and fuel channels—has been reproduced in the Michigan Ion Beam Laboratory as part of an effort to understand and prevent the phenomenon. Research led by Peng Wang, a University of Michigan assistant research scientist in nuclear engineering and radiological sciences, was published in the January 2022 issue of the Journal of Nuclear Materials and described in a recent university news article.

The Nuclear Regulatory Commission has denied “without prejudice” Oklo Power’s application to build and operate its Aurora microreactor in Idaho, the agency announced yesterday. The denial, according to the NRC, is due to the California-based firm’s failure to provide sufficient information on several crucial topics regarding the Aurora design.
