The Nonproliferation and Disarmament Challenges of Naval Nuclear Propulsion
A so-called loophole might allow a non-nuclear weapon state (NNWS) to use a naval reactor program to acquire nuclear weapons by taking nuclear material outside of safeguards and then potentially diverting some of that material. Additionally, nuclear-armed states with nuclear-powered warships might use their naval reactor programs to justify keeping a substantial inventory of highly enriched uranium (HEU)3 that could be quickly converted to nuclear weapon use or low enriched uranium (LEU) that could also be converted, but with more steps required to boost the LEU to HEU. Recognizing these and related nonproliferation and disarmament challenges, this report presents a proposal for the 2020 Non-Proliferation Treaty (NPT) Review Conference: a naval reactor quid pro quo (QPQ) for nuclear- armed states4 and NPT non-nuclear weapon states.
The Federation of American Scientists applauds the United States for declassifying the number of nuclear warheads in its military stockpile and the number of retired and dismantled warheads.
North Korea may have produced enough fissile material to build up to 90 nuclear warheads.
Secretary Austin’s likely certification of the Sentinel program should be open to public interrogation, and Congress must thoroughly examine whether every requirement is met before allowing the program to continue.
Researchers have many questions about the modernization of Pakistan’s nuclear-capable aircraft and associated air-launched cruise missiles.
