July 20, 2022, 7:00AMANS Nuclear Cafe

The Nuclear Innovation Alliance (NIA), a Washington, D.C.–based nonprofit, has released a new report, Advanced Nuclear Reactor Technology: A Company Compendium, along with an update to its Advanced Nuclear Reactor Technology: A Primer, first published last September.

Both reports are meant to serve as resources for investors, reporters, policymakers, regulators, and others wanting to learn more about the different technologies and key players involved in the design, licensing, construction, and operation of advanced nuclear reactors.

New Mexico State collaborates on spent fuel recycling under ARPA-E program

July 12, 2022, 12:00PMANS Nuclear Cafe

New Mexico State University is collaborating with TerraPower, Idaho National Laboratory, and Savannah River National Laboratory on a three-year project to develop a plan to recycle spent nuclear fuel. The project is being funded by an $8.5 million grant from the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E), under the Optimizing Nuclear Waste and Advanced Reactor Disposal Systems (ONWARDS) program. ONWARDS is designed to increase the use of nuclear power as a reliable, clean energy source, as well to as limit the amount of waste generated by advanced nuclear reactors.

The Gateway for Accelerated Innovation in Nuclear (GAIN) awarded vouchers to Orano Federal Services and TerraPower on June 22, giving them access to specialized facilities and expertise at Department of Energy national laboratories. Orano is partnering with Oak Ridge National Laboratory on a new technical study that updates the physical chemistry limits for the safe transport of uranium hexafluoride (UF6) gas enriched up to 10 percent in existing shipping containers, and TerraPower is turning to Los Alamos National Laboratory’s neutron testing capabilities to measure the properties of chlorine isotopes and determine how they will behave in the Molten Chloride Reactor Experiment (MCRE).

Isotek, the Department of Energy contractor responsible for overseeing the inventory of uranium-233 at Oak Ridge National Laboratory and preparing it for removal from the site, said it plans to resume preparations for processing high-dose U-233 in March. The company was forced to suspend its operational readiness review of the Initial Processing Campaign at Oak Ridge in January due to issues related to COVID-19, as well as difficulties operating in colder temperatures.

ANS to DOE: HALEU availability program needed ASAP

February 18, 2022, 9:30AMNuclear News

The American Nuclear Society is urging the Department of Energy to accelerate the development of an availability program for high-assay low-enriched uranium (HALEU).

In a letter sent to the DOE earlier this week, ANS President Steven Nesbit and Executive Director and Chief Executive Officer Craig Piercy state that HALEU availability is critical to the continued development of advanced nuclear technologies.

The Tennessee Valley Authority’s board of directors has given the go-ahead for a program that will explore the development and potential deployment of small modular reactors as part of the utility’s decarbonization strategy.

The need for a metallic nuclear fuels qualification plan

February 4, 2022, 3:13PMNuclear NewsHank Hogan, Steven Hayes, Nicolas Woolstenhulme, and Colby Jensen

Positioning nuclear power to combat climate change requires the rollout of advanced reactors to replace carbon-­emitting power generation. That necessity, and its urgency, is reflected in recent budget proposals for the Department of Energy’s Office of Nuclear Energy. Part of that proposed funding focuses on deploying new fuel technologies.

Metallic fuels, which are alloys of fissionable material, offer several advantages, including more fuel-­efficient reactors with a double or greater fuel burnup than the oxide fuels found in light water reactors. Fuel fabrication is also more cost-­effective with metallic fuels than with oxide fuels. Furthermore, much of the research and development effort needed to qualify these metallic fuels has been done.

TerraPower seeks fast reactor data through time-tested U.S.-Japan research ties

Natrium, a 345-MWe sodium fast reactor with a molten salt energy storage system, was developed by TerraPower and GE Hitachi Nuclear Energy. TerraPower is planning to build the first Natrium demonstration reactor by 2028 with 50-50 cost-shared funding of about $2 billion from the Department of Energy’s Advanced Reactor Demonstration Program. And for the requisite data and testing of reactor components to support that deployment, TerraPower is looking to Japan—a country with decades of experience developing sodium fast reactor designs and testing infrastructure.

Advanced reactors: Now comes the hard part

January 28, 2022, 2:26PMNuclear NewsMatthew L. Wald

Designing a reactor is complicated but building one may be harder. Even companies that have had lots of practice haven’t always done it well. And all the power reactors in service today were built by companies that had years of experience in other kinds of big steam-electric power plants. In contrast, some of the creative new designs now moving toward commercialization come from start-ups that have never built anything at all. How should they prepare?

Road to advanced nuclear: How DOE and industry collaborations are paving the way for advanced nuclear reactors

April 2, 2021, 8:58AMUpdated December 28, 2021, 3:38PMNuclear NewsCory Hatch

As 2021 closes, Nuclear News is taking a look back at some of the feature articles published each month in the magazine. The April issue reviewed the current state of advanced reactors. This article looks at how the DOE and private industry are working together to realize the benefits of advanced nuclear.

As electric utilities rush to reduce carbon emissions by investing in intermittent renewables such as wind and solar, they often rely heavily on fossil fuels to provide steady baseload power.

More than 60 percent of the nation’s electricity is still generated with fossil fuels, especially coal-fired and gas-fired power plants that have the ability to quickly ramp up or ramp down power to follow loads on the electric grid. Most experts agree that even with a radical advancement in energy storage technology, relying exclusively on wind and solar to replace fossil fuels won’t be enough to maintain a stable electric grid and avoid the major impacts of climate change.

New bill aims to bring advanced reactors to economically depressed communities

December 20, 2021, 9:30AMNuclear News

Bipartisan support for nuclear energy continued on Capitol Hill last week as Sens. Joe Manchin (D., W.Va.), chairman of the Senate Energy and Natural Resources Committee, and John Barrasso (R., Wyo.), the committee’s ranking member, introduced the Fission for the Future Act of 2021, a measure backing the commercial deployment of advanced nuclear reactors.

Introduced on December 16, the legislation would prioritize communities affected by the closure of coal and other fossil-fueled generating facilities and assist in the reutilization of those sites to deploy advanced nuclear power plants, promoting job growth in economically depressed regions.
