The bill removes the option of U.S. explosive nuclear testing—reducing environmental and catastrophic risks and preserving subcritical research—while constraining direct weapons validation and potentially increasing long‑term certification and defense costs for taxpayers.
All Americans (including taxpayers and future generations): The bill legally prohibits U.S. explosive nuclear tests, reducing the risk of full‑scale nuclear detonations and lowering the likelihood of environmental contamination and related cleanup costs.
Scientists and military personnel: The bill explicitly preserves the ability to conduct subcritical (non‑explosive) nuclear tests, maintaining tools for weapons safety checks and scientific research without resorting to explosive testing.
Federal weapons programs and taxpayers (including federal employees, scientists, and military planners): By banning explosive testing, the bill limits direct options for validating nuclear weapon performance, which could increase reliance on modeling or foreign testing alternatives and raise long‑term certification, maintenance, and defense procurement costs paid by taxpayers.
Based on analysis of 2 sections of legislative text.
Bars the U.S. from conducting explosive nuclear tests or other nuclear explosions and forbids federal funds from being used for such tests, while allowing subcritical tests.
Prohibits the United States from conducting any explosive nuclear test or any other nuclear explosion and bars federal funds from being used to carry out such tests. The bill preserves the ability to perform subcritical tests, which involve fissile materials but do not produce a nuclear chain reaction.
