Nuclear microreactors developed separately by Westinghouse and Radiant are poised to become the first fueled designs tested at the Demonstration of Microreactor Experiments (DOME) facility—the world’s first dedicated microreactor test bed slated to open at Idaho National Laboratory (INL) in early 2026. The first fueled experiment is expected to begin as early as spring 2026. […]

A company working to mass produce portable nuclear microreactors said its has accepted its selection by the U.S. Dept. of Energy (DOE) to receive high-assay low-enriched uranium (HALEU) fuel for the first test of Kaleidos, the group’s reactor design.

Westinghouse and Radiant Industries have secured a $5 million Department of Energy (DOE) award to advance their microreactor designs for testing at the Demonstration of Microreactor Experiments (DOME) testbed at Idaho National Laboratory (INL)— the world’s first facility, specifically designed to support fueled reactor experiments for advanced nuclear technologies. The two companies, along with Ultra […]

Another small modular reactor (SMR) design is moving closer to commercial operation after achieving a licensing milestone. GE Hitachi Nuclear Energy (GEH), which is designing the BWRX-300 SMR, on Dec. 1 said the U.S. Nuclear Regulatory Commission (NRC) has issued a final safety evaluation report for the first of several licensing topical reports (LTRs) submitted […]

A California company is gathering funding for development of a portable nuclear microreactor, designed for use in areas where other forms of power generation are not practical. Radiant, founded by former SpaceX engineers, on Sept. 22 said it has raised $1.2 million from angel investors as it designs what the company calls a “clean energy […]
