The Energy Department says a small nuclear reactor under development at a national lab has reached a crucial milestone that could allow it to produce electricity within a few years.
The microreactor being developed by Antares Nuclear Inc. at the Idaho National Lab reached “criticality” on Thursday, Energy Secretary Chris Wright said. The milestone occurs when a nuclear reactor achieves a self-sustaining chain reaction capable of producing a steady release of energy.
