The University of Illinois at Urbana-Champaign formed a partnership with Ultra Safe Nuclear Corporation to deploy an advanced research reactor on campus, based on a microreactor design that improves upon well-established high-temperature, gas-cooled reactor (HTGR) technology. Unlike traditional research reactors, our focus at UIUC is not on a laboratory tool to study radiation interactions with matter, or even on the production of radioisotopes. Instead, we will build a research, education, and training facility intended to help advanced reactor technology become a widely deployable, marketable, economic, safe, and reliable option for a clean energy future. If successful, the USNC-designed Micro Modular Reactor (MMR)^a would operate on UIUC’s campus with the capability to advance critical and enabling technologies required for advanced reactors to realize their full potential, while educating and training the workforce as a key step toward delivering on the technology’s promise. Microreactors can become a transformative distributed energy technology and revolutionize energy infrastructure worldwide.

The Canadian government has announced an investment of C$27.2 million (about $21.6 million) in Westinghouse Electric Canada to support the development of the company’s eVinci microreactor technology.

François-Philippe Champagne, Canada’s minister of Innovation, Science, and Industry, made the announcement on March 17 during a visit to the company’s Burlington, Ontario, facility.

The U.S. Department of Defense (DOD) is looking to reduce its reliance on local electric grids and diesel-fueled generators at military installations. Project Pele is designed to demonstrate the technical and safety features of mobile microreactors capable of generating up to 5 MWe.

Alaska Gov. Mike Dunleavy (R.) introduced “An act relating to microreactors” (SB 177) in the Alaska state legislature on February 1 that would modify existing state law on nuclear energy by specifying that microreactors are not subject to certain nuclear reactor siting and permitting regulations in Alaska. The bill defines a microreactor as an advanced nuclear fission reactor that would be capable of generating no more than 50 MWe.

The Nuclear Regulatory Commission’s announcement earlier this month that it was denying Oklo Power’s license application to build and operate its Aurora microreactor in Idaho caught a lot of people by surprise, not the least of whom were the people at Oklo.

This is the fifth of five articles posted today to look back at the top news stories of 2021 for the nuclear community. The full article, "Looking back at 2021,"was published in the January 2022 issue of Nuclear News.

Quite a year was 2021. In the following stories, we have compiled what we feel are the past year’s top news stories from the October-December time frame—please enjoy this recap from a busy year in the nuclear community.

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.

Westinghouse Electric Company has filed a pre-application regulatory engagement plan (REP) with the Nuclear Regulatory Commission for its eVinci microreactor, the company announced on Tuesday.

A recently completed feasibility study by Westinghouse Electric Company and Bruce Power concludes that the eVinci microreactor is capable of providing cost-competitive clean energy to decentralized, off-grid markets in Canada.

The Department of the Air Force has selected Eielson Air Force Base as the site of a stationary microreactor that “will provide the installation with a clean, reliable, and resilient nuclear energy supply technology for critical national security infrastructure,” the department announced on October 15.

With the goal of providing basic information on advanced reactors to help the public and stakeholders understand the technology’s promise, the nonprofit think tank Nuclear Innovation Alliance has published Advanced Nuclear Technology: A Primer.

The staff of the Nuclear Regulatory Commission recently released a draft white paper outlining strategies for streamlining microreactor licensing. The paper is to be used to facilitate discussion at an upcoming advanced reactor stakeholder public meeting.

“This paper,” the document emphasizes, “has not been subject to NRC management and legal reviews and approvals, and its contents are subject to change and should not be interpreted as official agency positions.”

A recently released technical report from Idaho National Laboratory finds “significant potential” for deploying microreactors on a global scale, but also “significant challenges in achieving the technical capacities, meeting regulatory requirements and international accords, achieving competitive costs, and for gaining public acceptance.”

In the 147-page report, Global Market Analysis of Microreactors, authors David Shropshire from INL, Geoffrey Black from Boise State University, and Kathleen Araújo from the CAES Energy Policy Institute at Boise State assess the unique capabilities of microreactors and their potential deployment in specific global markets in the 2030-2050 timeframe.

The House Committee on Appropriations last week approved an Energy and Water Development funding bill for fiscal year 2022 that provides an 11 percent increase for the Department of Energy’s Office of Nuclear Energy.

Reported favorably out of committee on July 16 via a party-line vote of 33 to 24, the House bill sports a total price tag of $53.2 billion, an increase of $1.5 billion from the FY 2021 enacted level. (The committee’s official report on appropriations for the next fiscal year can be found here.)

The Senate Energy and Natural Resources Committee yesterday approved a bill on energy infrastructure, including initiatives that would provide a boost to the U.S. nuclear industry.

Barasso

Murkowski

The Energy Infrastructure Act, which is expected to serve as the legislative text for key portions of a more comprehensive $1.2 trillion bipartisan infrastructure package, was approved 13–7, following the adoption of 48 amendments. All committee Democrats voted in favor of the bill, as well as three of the panel’s 10 GOP members, Sens. Bill Cassidy of Louisiana, Steve Daines of Montana, and Lisa Murkowski of Alaska. Two well-known Republican proponents of nuclear, John Barrasso of Wyoming and Jim Risch of Idaho, voted no. (Barrasso expressed a number of concerns with the bill, including its price tag.)

The U.S. state with more nuclear power plants than any other—Illinois—has no operating university research reactors. A team at the University of Illinois at Urbana-Champaign (UIUC) intends to reverse that situation and construct a high-temperature gas-cooled microreactor. If the team's plans go ahead, the first new U.S. university research reactor deployment in about 30 years could also support commercial advanced reactor deployment.

The definition of a microreactor is ambiguous. But whether your upper cutoff is 10 MW or 20 MW, the Microreactor Applications Research Validation and Evaluation (MARVEL) reactor that the Department of Energy plans to build is, at 100 kW, on the tiny side of micro.

Global First Power’s (GFP) Micro Modular Reactor (MMR) project has moved to the formal license review phase with the Canadian Nuclear Safety Commission (CNSC), becoming the first small modular reactor to do so.

Korsnick

Nuclear Energy Institute president and chief executive officer Maria Korsnick struck a decidedly optimistic tone last week in remarks on nuclear’s future delivered at the United States Energy Association’s 17th annual State of the Energy Industry Forum.

"In 2020, nuclear energy was highlighted in both House and Senate climate reports," she noted. "Congress significantly increased appropriations to accelerate research and development of new nuclear technologies. And we’ve seen the introduction of bipartisan legislation that recognizes nuclear’s contributions to today’s economy and our clean energy future.”
