Antares Microreactor Reaches Criticality

Antares Nuclear Incorporated, a private company, has achieved a crucial milestone by bringing its microreactor at the United States — Idaho National Laboratory to 'criticality' on June 4th. This means the reactor has achieved a self-sustaining chain reaction, a significant step towards producing electricity by late 2027 and deployment by late 2028, initially for military applications. This achievement is part of a pilot program initiated by the Donald Trump administration, which has also taken steps to remove regulatory barriers for nuclear power development, including limiting the authority of the United States — Nuclear Regulatory Commission. Energy Secretary Chris Wright hailed this as a historic day for the 'American nuclear renaissance'. While companies like Valar Atomics are also advancing microreactor technology, critics like Edwin Lyman of the Union of Concerned Scientists express skepticism about the safety and commercial viability of these developments, calling them 'publicity stunts'. The United States — United States Department of Energy is also exploring solutions for nuclear waste disposal.
