In a post dated April 7, 2025, Isaiah Taylor announced Valar was joining Texas, Utah, Louisiana, Florida and Arizona, and the reactor companies Last Energy and Deep Fission, in a lawsuit against the Nuclear Regulatory Commission. The argument, as Valar summarizes it, is that the Atomic Energy Act of 1954 narrowed federal licensing to reactors significant to defense or public safety, and that a 1956 rule wrongly swept in all reactors. The post says Valar's planned 'Ward One' test reactor is named in the suit. Litigation status and outcome are tracked in government.json.
