Advanced reactors take center stage in Popular Mechanics

December 17, 2020, 6:59AMANS Nuclear Cafe

The January/February 2021 issue of Popular Mechanics hit subscriber mailboxes this week with a stark cover image of a single small reactor under the headline, “Tiny nuclear reactors are about to revolutionize American energy.” The story looks at advanced reactors as a pivotal step to “redeem nuclear’s stature in American energy.”

A good primer: The article does a good job introducing the casual reader to the idea that “bigger is no longer better” and that the future of nuclear power in the United States will most likely be “a combination of traditional large plants and smaller, safer megawatt reactors.”

Advanced reactors, including small modular reactors, show that nuclear is no longer a one-size-fits-all operation, the article notes. The industry now “is all about personalization,” says Ken Canavan, Westinghouse’s chief technical officer, who is quoted in the article. The capacity and scalability of SMRs “is just irreplaceable,” he adds.

The article explains that SMRs, microreactors, and other advanced reactor designs will be able to bring reliable, carbon-free power to small or remote locations, replacing fossil fuel power plants and supplementing the “resource-sucking downtimes left by renewables.”

Advanced reactors important for carbon-free power production in U.S., tweets Vice News

A video posted to Twitter by Vice News discusses the prospect of advanced reactors being an important mix of carbon-free power production in the United States. Hosted by Gelareh Darabi, an award-winning Canadian-British-Iranian journalist and documentary filmmaker, the video provides quick and easy statistics for the general audience and pulls from social media influencer I_sodope. It also includes comments from nuclear experts.

U.K. sets plans for clean energy and green jobs by 2050

December 14, 2020, 2:59PMNuclear News

A 170-page energy white paper, Powering Our Net Zero Future, issued by the United Kingdom government on December 14 sets big goals for cleaning up the U.K.’s energy system. According to the U.K. government, the plan would create and support green energy jobs across England, Scotland, Wales and Northern Ireland and would keep electricity bills affordable as the U.K. transitions to net zero emissions by 2050.

The white paper notes that the U.K. will generate emission-free electricity by 2050 with a trajectory that will see "overwhelmingly decarbonized power in the 2030s. Low carbon electricity will be a key enabler of our transition to a net zero economy with demand expected to double due to transport and low carbon heat."

The white paper builds upon the U.K. prime minister’s 38-page Ten Point Plan for a Green Industrial Revolution, which was issued on November 18.

New Brunswick debates investing in SMRs

In an article published by the Canadian Broadcasting Corporation on December 7, politicians representing New Brunswick, Canada, debate the benefits and potential risks of investing in small modular reactor development. Two major parties in the province support SMR development, while the Green Party sees “danger signs.”

2020 ANS Virtual Winter Meeting: Advanced nuclear reactors and power systems

November 20, 2020, 1:04PMNuclear News

“Advanced Nuclear Reactors and Power Systems-I” on November 18 during the 2020 ANS Virtual Winter Meeting was the first of a three-session set examining the status of various advanced reactors. The sessions were sponsored by the Operations and Power Division and chaired by Piyush Sabharwall of Idaho National Laboratory.

Presentation topics in the first session included the core design and helium Brayton cycle design of the Holos-Quad microreactor, a microreactor design for a truck charging station, and a levelized cost of electricity (LCOE) estimation on HALEU (high-assay low-enriched uranium) fuels for small modular reactors.

Here are some highlights:

With DOE funds in hand, UAMPS preps for NuScale SMR licensing phase

Utah Associated Municipal Power Systems (UAMPS) announced on October 16 that the Department of Energy has approved a $1.4-billion, multiyear cost-share award to Carbon Free Power Project LLC, a new business entity wholly owned by UAMPS that was created for the development and construction of a 720-MWe NuScale power plant—the Carbon Free Power Project (CFPP)—to be sited at Idaho National Laboratory. The funding comes as UAMPS prepares to develop the first combined license application (COLA) for a small modular reactor.

CNL and Kairos Power reach agreement on tritium research

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.

UAMPS clarifies next steps for planned NuScale SMR deployment

With a design that has just emerged from a rigorous safety evaluation by the Nuclear Regulatory Commission, and a customer—Utah Associated Municipal Power Systems (UAMPS)—getting ready to prepare a combined license (COL) application, what is next for Oregon-based NuScale Power and for near-term small modular reactor prospects in the United States? As milestones are reached, many want to know.

NuScale plans to supply twelve 60-MWe modules for a 720-MWe plant—called the Carbon Free Power Project (CFPP) by UAMPS—to be sited at Idaho National Laboratory. A smaller, 50-MWe module version of NuScale’s design recently became the first SMR to receive a final safety evaluation report (FSER) from the Nuclear Regulatory Commission.

“The NRC design approval represents a significant de-risking factor for the CFPP,” said UAMPS spokesperson LaVarr Webb. The project is “making steady progress,” Webb said, adding that “UAMPS General Manager and CEO Doug Hunter has said it is much more important to do the project right than to do it fast.”

SMR designs once again a focus at ANS Winter Meeting 2012

Small Modular Reactors, or SMRs, have been under consideration in many quarters of late as a new focus for nuclear power generation. While the recent deadline for Department of Energy grant money came and went without so much as a whisper from the DOE, the concept continues to be developed. Quite a few presentations have been made, as a result, on reactors of this class here at the ANS 2012 Winter Meeting.
