Nuclear Weapons Abolition and Conversion Act of 2023

This bill directs the U.S. government to support global nuclear disarmament by urging the U.S. to sign and ratify the Treaty on the Prohibition of Nuclear Weapons, contingent on ratification leading to verified worldwide elimination of nuclear weapons under international control. If the President certifies that all nuclear-armed nations have begun verified, irreversible elimination under the treaty, the U.S. must redirect funds currently used for nuclear weapons programs to: (1) develop clean energy and retrain nuclear industry workers; (2) address social needs like healthcare, housing, and environmental restoration (including radioactive waste monitoring); and (3) encourage other nations to join the treaty. It directly affects U.S. federal funding streams, nuclear weapons industry workers, and federal agencies managing defense resources. The bill focuses on policy shifts in resource allocation rather than creating new programs or mandating specific disarmament timelines.
