Terrestrial Energy has upgraded the design of its Integral Molten Salt Reactor (IMSR) nuclear power plant, the company announced on September 14. The proposed facility will now feature 390 MWe of generation capacity for grid supply from twin reactors and generators.

CNSC, NRC complete joint report on the Xe-100 SMR

August 19, 2021, 12:00PMNuclear News

The Canadian Nuclear Safety Commission and the U.S. Nuclear Regulatory Commission have completed the first collaborative project under a two-year-old memorandum of cooperation (MOC) aimed at enhancing technical reviews of advanced reactor and small modular reactor technologies, the CNSC announced earlier this week.

The project, a 23-page joint report from the regulators on a white paper submitted last July by X-energy regarding reactor pressure vessel (RPV) construction code specifications for the company’s Xe-100 SMR, was released to the public on August 6. The Xe-100 is an 80-MWe unit that can be scaled into a “four-pack” 320-MWe power plant, according to X-energy.

Biden administration’s proposed FY 2022 budget supports nuclear

June 3, 2021, 3:02PMNuclear News

The Biden administration’s fiscal year 2022 budget sent to Congress last week would, according to the Department of Energy, move the United States toward net-zero carbon emissions by 2050. The FY 2022 budget request includes $1.85 billion for the DOE’s Office of Nuclear Energy.

“President Biden’s budget request puts America in the driver's seat as we transition toward a 100 percent clean energy economy,” said secretary of energy Jennifer Granholm on May 28. “These investments will ensure the U.S. is the global leader in research, development, and deployment of critical energy technologies to combat the climate crisis, create good-paying union jobs, and strengthen our communities in all pockets of America.”

Building the nation’s first advanced reactor is the goal of a partnership formed between X-energy, Energy Northwest, and the Grant County (Washington) Public Utility District (PUD).

The TRi Energy Partnership will support the development and demonstration of X-energy’s Xe-100 high-temperature gas reactor, which was selected by the Department of Energy for a cost-shared commercial demonstration by 2027 through the DOE’s Advanced Reactor Demonstration Program (ARDP). The new partnership was announced on April 1, when Clay Sell, X-energy’s chief executive officer; Brad Sawatzke, Energy Northwest’s CEO; and Kevin Nordt, the Grant County PUD’s CEO, met in Richland, Wash., to sign a memorandum of understanding.

NCSU to host SMR technical library with support from endowment

April 1, 2021, 9:32AMNuclear News

The North Carolina State University (NCSU) Libraries Department and the Department of Nuclear Engineering are collaborating to build a small modular reactor technical library at NCSU. The library resources will be available to the NCSU research community and to TerraPower/GE Hitachi and X-energy, both of which have signed teaming agreements with NCSU researchers to support planned advanced reactor demonstrations within the next seven years.

Making the new library collection possible: a generous donation from NCSU alumnus Stephen Rea, who together with his wife, Phyllis, formed the Stephen and Phyllis Rea Endowment for Mechanical Engineering Collections in 2015.

“We wanted to seed the endowment and grow it through donations to pursue research and development of green advanced power generation technologies,” Rea explained. “Supporting the advancement of SMR technology development fits our mission statement perfectly.”

The Department of Nuclear Engineering at North Carolina State University has spent the 2020–2021 academic year celebrating the 70th anniversary of its becoming the first U.S. university to establish a nuclear engineering curriculum. It started in 1950, when Clifford Beck, then of Oak Ridge, Tenn., obtained support from NC State’s dean of engineering, Harold Lampe, to build the nation’s first university nuclear reactor and, in conjunction, establish an educational curriculum dedicated to nuclear engineering.

The department, host to the 2021 ANS Virtual Student Conference, scheduled for April 8–10, now features 23 tenure/tenure-track faculty and three research faculty members. “What a journey for the first nuclear engineering curriculum in the nation,” said Kostadin Ivanov, professor and department head.

DOD narrows field of Project Pele microreactor contenders

March 25, 2021, 9:29AMNuclear News

After funding one year of microreactor engineering design work by three teams, the Department of Defense (DOD) announced on March 22 that it has exercised contract options for two of those teams—led by BWXT Advanced Technologies and X-energy—to proceed with development of a final design for a transportable microreactor. Following a final design review in early 2022 and the completion of environmental analysis, one of the two companies may be selected to build a prototype reactor during a 24-­month construction and demonstration phase.

“We are thrilled with the progress our industrial partners have made on their designs,” said Jeff Waksman, Project Pele program manager. “We are confident that by early 2022 we will have two engineering designs matured to a sufficient state that we will be able to determine suitability for possible construction and testing.”
