Energy and Water Development Appropriations: Nuclear Weapons Activities [Updated July 29, 2019] [open pdf - 1MB]
From the Summary: "The annual Energy and Water Development appropriations bill funds civil works projects of the Army Corps of Engineers, the Department of the Interior's Bureau of Reclamation, the Department of Energy (DOE), and several independent agencies. The DOE budget includes funding for the National Nuclear Security Administration (NNSA), a separately organized agency within DOE. NNSA operates three programs: Defense Nuclear Nonproliferation, which secures nuclear materials worldwide, conducts research and development (R&D) into nonproliferation and verification, and operates the Nuclear Counterterrorism and Incident Response Program; Naval Reactors, which 'is responsible for all U.S. Navy nuclear propulsion work'; and Weapons Activities. The last is the subject of this report."
