Dry Ice Blasting: A Game-Changer for Safe Cleaning and Decontamination in Nuclear Power Plants
Kairos Power has filed a construction permit application with the Nuclear Regulatory Commission for a two-unit version of its Hermes advanced test reactor.
Tennessee Gov. Bill Lee has announced appointments to his Tennessee Nuclear Energy Advisory Council, established recently via executive order to help position the Volunteer State as a national leader in nuclear innovation.
The Nuclear Regulatory Commission staff has completed its final safety evaluation for Kairos Power’s application to build its Hermes advanced test reactor at a site in Oak Ridge, Tenn., the agency announced recently. The evaluation found no safety aspects precluding issuance of a construction permit for the proposed reactor.
Ontario Power Generation—owner and operator of Canada’s Darlington and Pickering nuclear plants—and Poland’s ORLEN Synthos Green Energy (OSGE) have signed a letter of intent (LOI) that builds on the companies’ existing cooperation on the deployment of small modular reactors in Europe, OPG announced last week.

In his latest effort to promote the growth of nuclear energy in his state, Tennessee Gov. Bill Lee signed an executive order on Tuesday to establish the Tennessee Nuclear Energy Advisory Council.
“Tennessee is ready-made to lead America’s energy independence and drive continued economic growth with safe, clean, and reliable nuclear energy for the future,” Lee said at a news conference held at the University of Tennessee’s Knoxville campus to publicize the document. “Today, I’m signing an executive order that will continue our work to make Tennessee the number-one state for nuclear energy companies to invest and thrive, bringing greater opportunity and quality jobs for Tennesseans.”
In the new year, ANS launched Trustees of Nuclear, a corporate partnership program ANS executive director/chief executive officer Craig Piercy announced in the January issue of Nuclear News (p. 25). The goal of Trustees of Nuclear is to directly support ANS’s programs aimed at improving nuclear literacy, like the Society’s K-12 nuclear STEM activities, public engagement, and discussions with policymakers. As the main professional organization for the whole nuclear discipline, ANS is in a unique position to unite leaders in the nuclear community to focus on these long-term programs and help the country realize the full potential of the atom.
“I’m glad you came to our party!” said GE Hitachi Nuclear Energy (GEH) chief nuclear officer Nicole Holmes as she prepared to announce that Wilmington, N.C.–based GEH will develop a standard design for its BWRX-300 boiling water small modular reactor with not one but three power producers representing three countries: Tennessee Valley Authority (TVA), Ontario Power Generation (OPG), and Synthos Green Energy (SGE). Celebration was a theme throughout the March 23 event held in Washington, D.C., which was flush with dignitaries representing the United States, Canada, and Poland.
The Tennessee Valley Authority took Browns Ferry-2 off line February 17 for a refueling and maintenance outage, following a nearly two-year, breaker-to-breaker run—the first in the Alabama nuclear plant’s history.
According to the utility, the unit established a new record for itself with 665 days of continuous operation, producing more than 20 billion kilowatt-hours of electricity.
Estonia’s Fermi Energia has selected GE Hitachi Nuclear Energy’s BWRX-300 small modular reactor for potential deployment in that European country, GEH announced on February 8.
Wilmington, N.C.–based GE Hitachi Nuclear Energy and Canadian firms Ontario Power Generation, SNC-Lavalin, and Aecon announced this morning the signing of a contract for the deployment of a BWRX-300 small modular reactor at OPG’s Darlington nuclear site in Canada. According to the announcement, it is the first commercial contract for a grid-scale SMR in North America.
Another calendar year has passed. Before heading too far into 2023, let’s look back at what happened in 2022 for the American Nuclear Society and the nuclear community. In today's post that follows, we have compiled from Nuclear News and Nuclear Newswire what we feel are the top nuclear news stories from April through June 2022.
Stay tuned this week for the top stories from the rest of the past year.

The Steam Generating Team (SGT)—a joint venture of Framatome and United Engineers & Constructors Inc.—has completed a project to replace the Unit 2 steam generators at the Watts Bar nuclear plant, Framatome announced last week.
Watts Barr’s owner and operator, the Tennessee Valley Authority, awarded Framatome the contract for the work in early 2020.
The Gateway for Accelerated Innovation in Nuclear (GAIN) announced the three recipients of its fourth and final round of 2022 vouchers on October 10. The vouchers were awarded to Curio Solutions, which is developing a spent fuel recycling process, and to two companies that are separately investigating advanced reactor siting—Elementl Power and the Tennessee Valley Authority (TVA). The funds for each award will go directly to Oak Ridge National Laboratory.
The Nuclear Regulatory Commission issued a draft environmental impact statement (EIS) recently on Kairos Power’s application for a permit to construct Hermes, a 35-MW nonpower version of the company’s fluoride salt–cooled reactor design (KP-FHR), at the East Tennessee Technology Park in Oak Ridge, Tenn.
The Tennessee Valley Authority and GE Hitachi Nuclear Energy (GEH) have signed an agreement to support planning and preliminary licensing for the potential deployment of a BWRX-300 small modular reactor at the Clinch River site near Oak Ridge, Tenn., the utility’s president and chief executive officer, Jeff Lyash, announced last week.
An evolution of GEH’s 1,520-MWe Generation III+ ESBWR design, the BWRX-300 is a 300-MWe water-cooled, natural-circulation SMR with passive safety systems.
As part of its strategy to achieve net-zero status by 2050, the Tennessee Valley Authority yesterday issued a request for proposals for supplying up to 5 GW of carbon-free energy that must be operational before 2029.
Jennifer Call, Meteorologist: When you think of a meteorologist, what is the first thing that comes to mind? For many it is your local TV meteorologist delivering a weathercast for the 5 o’clock news, or perhaps a meteorologist at the National Weather Service issuing severe storm warnings. But did you know that utilities rely on meteorologists for daily support?

The United States has just 93 operating power reactors at this writing. The fleet last numbered 93 in 1985, when nuclear generation topped out at 383.69 TWh, less than half of the 778.2 TWh produced in 2021.
While the 93 reactors operating today have more capacity, on average, than in 1985, most of that increased productivity is down to operational improvements that pushed the fleet’s average capacity factor from just 57.5 percent in the three-year period 1984–1986 to near 90 percent by the early 2000s.
Kairos Power announced today that it has assembled an advanced nuclear development advisory consortium with four North American nuclear operators—Bruce Power, Constellation, Southern Company, and the Tennessee Valley Authority—dubbed Kairos Power Operations, Manufacturing and Development Alliance (Kairos Power-OMADA).
