Terrestrial Energy submitted its Thermal and Electric Facility (TEF) Topical Report to the U.S. Nuclear Regulatory Commission (NRC), the company announced.

The filing seeks approval to build and operate the non-nuclear portions of its Integral Molten Salt Reactor Plant separately from the nuclear components.

If approved, the facility could be constructed and operated before the company obtains a nuclear construction permit and operating license, according to Terrestrial Energy.

The U.S. Department of Energy approved the nuclear safety design agreement, or NSDA, for Deep Fission's reactor in southeast Kansas.

The approval is an initial step in the federal safety review process. Deep Fission still needs additional documentation and reviews before it can secure federal authorization to operate.

Iceberg Research criticized the company's plans. In its report, Iceberg Research argued that power from the reactor would not be competitive and that the timeline for approval and construction was too ambitious.

Following that report, four stockholder rights law firms announced they were investigating Deep Fission.

NASA has signed an agreement with the US Department of Energy to develop nuclear-powered spacecraft and lunar reactors, according to Fudzilla. The report describes the deadlines attached to the deal as ambitious.

The collaboration will span reactor research, nuclear fuel production, testing, launch integration and operations, according to Fudzilla.

NASA administrator Jared Isaacman said nuclear power would let the agency go farther, operate longer, and field more capable spacecraft and instruments than before.

Geenex Power has disclosed the proposed site for its small modular nuclear reactor in Amherst County. The location covers about 250 acres between Joshua Falls Road and a bend of the James River, south of Galts Mill Road, according to Cardinal News.

The project, named Beck Creek Energy, is planned to produce up to 650 MW.

Geenex said it chose the site partly for its proximity to an Appalachian Power substation and a connected high-voltage transmission line able to carry that much power.
