Southern Company, TerraPower, and Core Power (a U.K.-based firm focused on developing nuclear technologies for the maritime sector) have commenced pumped-salt operations in the Integrated Effects Test (IET) facility, the Atlanta, Ga.-based utility announced Tuesday, marking another milestone in the development of TerraPower’s first-of-a-kind, Generation IV Molten Chloride Fast Reactor (MCFR).

Terrestrial Energy, Westinghouse ink deal for IMSR fuel plant

August 4, 2023, 9:30AMNuclear News

Canadian nuclear tech firm Terrestrial Energy has signed a manufacturing and supply contract with Springfields Fuels Limited—a Britain–based subsidiary of Westinghouse Electric Company—for the design and construction of an Integral Molten Salt Reactor (IMSR) fuel pilot plant.

In an August 3 press release, Terrestrial said that Springfields’ reactor fuel manufacturing facility has extensive existing infrastructure available to support the fuel supply for IMSR development and is scalable to support a fleet of IMSR plants operating in the 2030s. Located near Preston, Lancashire in northwestern England, the Springfields facility is the only site in the United Kingdom for nuclear fuel manufacturing.

The Canadian Nuclear Safety Commission (CNSC) has completed phase two of its prelicensing vendor design review for Terrestrial Energy’s Integral Molten Salt Reactor (IMSR), the Ontario-based advanced nuclear technology firm announced Tuesday. Phase one of the VDR commenced in April 2016 and was completed in November of the following year.

X-energy, Alberta explore opportunities to support SMR projects

February 7, 2023, 12:00PMNuclear News

X-energy Canada, a subsidiary of U.S. mall modular reactor and fuel technology company X-energy, has signed a memorandum of understanding with Invest Alberta Corporation (IAC) to develop economic opportunities in support of the potential deployment of the Xe-100 SMR in the western Canadian province. (Alberta is one of four provinces behind last year’s A Strategic Plan for the Deployment of SMRs—a document that maps the path to capitalizing on the benefits of advanced reactor deployment.)

Terrestrial Energy chosen for coal conversion program

November 8, 2022, 12:05PMNuclear News

Ontario’s advanced nuclear technology firm Terrestrial Energy yesterday announced the signing of a letter of intent (LOI) with TerraPraxis, a U.K.-based nonprofit devoted to climate solutions, to cooperate on the latter’s Repowering Coal initiative—a program aimed at integrating clean heat sources with existing infrastructure at coal-fired power plants in North America and elsewhere.

Westinghouse Electric Company and Ansaldo Nucleare have announced the signing of a cooperation agreement to develop a next-generation nuclear power plant based on lead-cooled fast reactor (LFR) technology.

Wholly owned by Italy’s Ansaldo Energia, Ansaldo Nucleare is involved in the production of high-tech nuclear components; the design and construction of new builds; decommissioning; and advanced research on radwaste management, fusion, fourth-generation plants, and small modular reactors. In addition, the firm played a significant role in the development of such Generation III technologies as Westinghouse’s AP600 and AP1000 reactors.

Under the agreement, Westinghouse and Ansaldo Nucleare will advance a common design to maximize synergies; combine experience in design, testing, and licensing; and align respective partner and supply-chain organizations.

In the ongoing quest to mitigate the effects of climate change, new technology can create new solutions. Even today, however, coal is still a main source of power around the globe, often out of necessity. Many coal-burning plants have already been converted for gas or biomass, but these measures alone are not nearly enough to meet net-zero carbon goals. There is a better solution, however: repowering coal plants with nuclear technology—specifically, Generation IV reactors.

Pact signed to advance IMSR development in western Canada

August 12, 2022, 9:29AMNuclear News

Evidence that Canada is serious about becoming a world leader in small modular reactor deployment continues to mount. Ontario-based SMR developer Terrestrial Energy yesterday inked a memorandum of understanding with Invest Alberta—a crown corporation of the government of Alberta that promotes the province internationally—to support commercialization of the company’s Integral Molten Salt Reactor (IMSR) in western Canada.

X-energy picks constructor collaborators
