The Department of Energy’s Office of Environmental Management on May 27 issued a final request for proposals for the cleanup of the Idaho National Laboratory site, near Idaho Falls, Idaho, and the Fort Saint Vrain facility near Platteville, Colo. The 10-year contract for the projects—collectively called the Idaho Cleanup Project—has an estimated ceiling of about $6.4 billion.

Reactor designers and others ready to invest in advanced nuclear technology now have a defined route to apply for cost-share funding, including $160 million in initial funding to build two reactors within the next five to seven years. On May 14, the U.S. Department of Energy issued a funding opportunity announcement (FOA) for the new Advanced Reactor Demonstration Program (ARDP).

When it comes to advanced, high-temperature reactors—using working fluids such as molten salt, high-temperature gases, or sodium—there simply are not many qualified materials for nuclear component construction. Alloy 617 is not a new material, but it made the news after Idaho National Laboratory announced that it was recently added to the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV) Code for high-temperature nuclear applications, bringing the total number of qualified high-temperature materials to six.

Battelle Energy Alliance, the managing and operating contractor for Idaho National Laboratory, is seeking an expression of interest (EOI) from industry stakeholders interested in forming a partnership to develop and/or demonstrate advanced construction technologies and processes. The effort would be executed as an initiative of the National Reactor Innovation Center (NRIC) at INL. Battelle announced the EOI on April 17, with a deadline for responses of May 16.

ANS Young Members Group Chair Harsh Desai

The ANS Young Members Group has developed a new live webinar series that is free to all, and Harsh Desai is excited. “We have a great opportunity to highlight our national laboratory infrastructure, which is a pinnacle of innovation in nuclear science, technology, and engineering,” said Desai, chair of the YMG. “We’re giving each of the national labs the opportunity to highlight their mission, key projects, and rising stars, and we’re also giving members of the YMG executive committee valuable leadership experience building and moderating the webinar panels.”

Advanced reactor cores are being designed for higher efficiencies and longer lifetimes, but to get there, they need high-assay low-enriched uranium (HALEU).

Enriched to between 5 and 19.75 percent fissile U-235, HALEU is packed with nuclear potential. It can be used as a feedstock for the demonstration of new fuel designs, from uranium alloys to ceramic pellets and liquid fuels. Those fuels can enable advanced reactor and microreactor demonstrations. Operating light-water reactors could potentially transition to HALEU uranium oxide fuels for extended operating cycles and improved plant economics.
