Back in July, officials from the state of Tennessee and Kairos Power met in Nashville to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The demonstration facility is a scaled-down version of Kairos’s Fluoride Salt–Cooled High Temperature Reactor (KP-FHR), dubbed Hermes. The company first announced plans in December 2020 to redevelop the ETTP’s former K-33 gaseous diffusion plant site for construction of Hermes.

Day three of the 2021 Utility Working Conference commenced early Tuesday morning with a plenary session featuring Rita Baranwal, the Electric Power Research Institute’s vice president of nuclear and chief nuclear officer, and Greg Cullen, Energy Northwest’s vice president for energy services and development.

Today, Tennessee governor Bill Lee joined Department of Economic and Community Development commissioner Bob Rolfe and Kairos Power officials in Nashville, Tenn., to celebrate Kairos’s plans to construct a low-power demonstration reactor in the East Tennessee Technology Park in Oak Ridge, Tenn. The company first announced its plans to redevelop the former K-33 gaseous diffusion plant site at the Heritage Center, a former Department of Energy site complex, in December 2020.

The pace of advances in nuclear instrumentation, controls, and human-machine interface technologies and their deployment has increased in recent years and are essential to achieving the enhanced safety and improved economics of advanced reactors.

The Nuclear Innovation Alliance (NIA) yesterday released a report, Unlocking Advanced Nuclear Innovation: The Role of Fee Reform and Public Investment, arguing that a reform of the Nuclear Regulatory Commission’s user-fee model for new license applicants, combined with more funding for advanced reactor licensing and regulatory infrastructure, will unlock innovation and support U.S. leadership in advanced nuclear energy.

The 38-page report asserts that as currently structured, the NRC’s fee model inhibits carbon-free advanced nuclear innovation in two primary ways: First, it limits the agency’s resources, flexibility, and efficiency; and second, the open-ended costs associated with paying fees impose barriers to new entrants.

The Tennessee Valley Authority and nuclear technology and engineering company Kairos Power this morning announced plans to collaborate on the deployment of the latter’s low-power demonstration reactor, dubbed Hermes, at the East Tennessee Technology Park (ETTP) in Oak Ridge, Tenn. TVA will provide engineering, operations, and licensing support to help Kairos with deployment, according to the announcement.

The Department of Energy today announced $30 million in initial fiscal year 2020 funding—with the expectation of more over the next seven years—for five companies selected for risk reduction for future demonstration projects. The chosen reactor designs from Kairos Power, Westinghouse, BWX Technologies, Holtec, and Southern Company collectively represent a range of coolants, fuel forms, and sizes—from tiny microreactors to a molten salt reactor topping 1,000 MWe. They were selected for cost-shared partnerships under the Office of Nuclear Energy’s Advanced Reactor Demonstration Program (ARDP) through a funding opportunity announcement issued in May 2020.

“All of these projects will put the U.S. on an accelerated timeline to domestically and globally deploy advanced nuclear reactors that will enhance safety and be affordable to construct and operate,” said Energy Secretary Dan Brouillette. “Taking leadership in advanced technology is so important to the country’s future, because nuclear energy plays such a key role in our clean energy strategy.”

Kairos Power plans to site a test reactor it has dubbed Hermes at the East Tennessee Technology Park (ETTP) in Oak Ridge, Tenn. The company has executed a Memorandum of Understanding with Heritage Center, LLC, to acquire the former K-33 gaseous diffusion plant site at ETTP, subject to ongoing due diligence evaluations. The announcement was made today, during the 2020 East Tennessee Economic Council Annual Meeting and Awards Celebration.

“We are thrilled at the prospect of coming to East Tennessee,” said Michael Laufer, cofounder and chief executive officer of Kairos Power. “The infrastructure available at ETTP, combined with its proximity to key collaborators at the Oak Ridge National Laboratory, makes this a great location to demonstrate our technology. The successful commissioning of Hermes builds on our current technology development programs and extensive engagement with the U.S. Nuclear Regulatory Commission. Ultimately, Hermes will prove that Kairos Power can deliver real systems at our cost targets to make advanced nuclear a competitive source of clean energy in the United States.”

Lou Martinez, vice president of strategy and innovation, added, “Today is an important day for Kairos Power. We are celebrating our 4th anniversary by showcasing an important milestone.”

Canadian Nuclear Laboratories (CNL) on September 3 announced a research collaboration agreement with Kairos Power. Funded through CNL’s Canadian Nuclear Research Initiative (CNRI), the agreement includes research and engineering for technologies to separate, analyze, and store the tritium that would be created during the operation of Kairos Power’s proposed fluoride-salt–cooled small modular reactor.
