No Nuclear Testing Without Approval Act

HR 5951, the No Nuclear Testing Without Approval Act, requires the U.S. President to obtain Congressional approval before conducting any explosive nuclear testing. It applies directly to the executive branch and Congress, mandating a 180-day notice period and detailed justification for testing - either in response to foreign nuclear activity or due to a "technical need" (e.g., safety, reliability, or performance issues with nuclear weapons). Congress must pass a joint resolution approving the testing, requiring a two-thirds vote in the Senate for both scenarios. The bill does not ban testing but changes the process to ensure legislative oversight, with specific timelines and procedural rules for congressional consideration.
