The bill increases transparency and congressional control to limit U.S. explosive nuclear testing and lower environmental risk, but does so at the cost of slower, potentially politicized and less-secretable decisionmaking that could impair rapid national-security responses and raise costs if testing is triggered by foreign actions.
All Americans: Restricts U.S. explosive nuclear testing, reducing the risk of new environmental contamination and radioactive fallout.
Congress and the public: Requires a 180-day unclassified notification (with optional classified annex) including reasons, timelines, and cost estimates, increasing transparency and enabling public and congressional oversight.
Congress: Requires a joint resolution to approve any explosive nuclear test, preserving congressional authority and legislative oversight over testing decisions.
Military personnel and federal decisionmakers: The 180-day notice period plus the required congressional joint-resolution approval could slow urgently needed nuclear-testing decisions after a foreign test or emerging threat.
Military personnel and federal employees: Requiring congressional passage (including a two-thirds Senate vote when responding to foreign tests) risks politicizing technical military judgments about whether testing is necessary.
Federal employees and military personnel: Mandating an unclassified notification (even with a classified annex) and public congressional procedures could constrain rapid, secret responses needed for some national-security actions.

Prohibits U.S. explosive nuclear testing unless the President notifies Congress 180 days in advance and Congress enacts a joint resolution approving the test, with special voting/timing rules.
Introduced November 5, 2025 by Catherine Marie Cortez Masto · Last progress November 5, 2025
Changes federal law to bar the United States from carrying out explosive nuclear tests after enactment except in narrowly defined circumstances. A test may proceed only if the President first notifies Congress at least 180 days in advance with specified information and Congress enacts a joint resolution approving the test under defined procedures and voting rules. The measure defines two paths: a special expedited approval path for tests justified by a technical need, and a slower, higher‑threshold path for tests taken in response to a foreign state's test (including a two‑thirds Senate requirement and no expedited procedures). It also prescribes detailed congressional referral, reporting, timeline, and floor procedures for considering the joint resolution of approval.
