To require the approval of Congress before explosive nuclear testing may be resumed.

Summary
What This Bill Does
The No Nuclear Testing Without Approval Act prohibits the United States from conducting explosive nuclear weapons tests unless Congress passes a joint resolution approving the test after receiving detailed notification from the President at least 180 days in advance. The bill creates two pathways for testing: if a foreign country conducts a nuclear test, the President must still get Congressional approval with a two-thirds vote in the Senate; if there is a documented technical need for testing, an expedited Congressional approval process applies but still requires a two-thirds Senate vote.
Who Benefits and How
Congress and Congressional oversight advocates benefit by gaining formal veto power over executive branch decisions to resume nuclear testing. The House and Senate Armed Services Committees receive mandatory consultation and voting authority, shifting the balance of power from unilateral executive action to a shared decision-making process. Arms control organizations and environmental groups benefit because the bill creates a significant procedural barrier to resuming nuclear testing, requiring public debate and supermajority Congressional approval. State governments, particularly Nevada where the Nevada Test Site is located, gain a formal consultative role as the bill requires engagement with the Governor of any state where testing would occur.
Who Bears the Burden and How
The Executive Branch—specifically the President, Department of Energy, and National Nuclear Security Administration—loses the unilateral authority to conduct nuclear weapons tests and must navigate a complex Congressional approval process with significant time delays (minimum 180 days notice). Nuclear weapons laboratories like Los Alamos, Lawrence Livermore, and Sandia face new barriers if they determine explosive testing is necessary for weapon safety or reliability, as they must justify why alternative approaches like subcritical experiments are insufficient. Defense contractors and advocates who view nuclear testing as important for maintaining deterrence credibility face reduced opportunities as Congressional approval becomes a significant hurdle.
Key Provisions
• Amends the Atomic Energy Defense Act to prohibit explosive nuclear testing after enactment unless Congress approves via joint resolution
• Requires the President to submit detailed notification to Congress at least 180 days before any proposed test, explaining the technical or geopolitical justification
• Creates expedited Congressional procedures for considering approval resolutions (60-day committee review, limited floor debate) but requires two-thirds Senate vote for passage in all cases
• Defines "explosive nuclear testing" to explicitly exclude subcritical experiments, laser fusion, and other non-fission experiments, allowing continued stockpile stewardship research
• Mandates consultation with the Governor of the state where testing would occur as part of the notification process

Key Definitions
Terms defined in this bill
A joint resolution of either House of Congress with specific language approving the President's proposal to conduct explosive nuclear testing for which there is a technical need
Testing involving the explosive compression or assembly of fissile material to exceed critical mass with the attendant release of any nuclear energy from fission processes; excludes subcritical experiments, laser fusion experiments, and other inertial confinement fusion experiments
All officials specified in section 4205(b) determine that an explosive nuclear test is necessary to resolve an issue with respect to the safety, reliability, performance, or military effectiveness of a nuclear weapon type
