Charting the Course: Australia’s Nuclear Submarines and the International Nuclear Safeguards and Non-Proliferation Regime

Key points

  • Australia’s nuclear submarine acquisition under the AUKUS partnership is lawful and represents an opportunity to establish new norms in international nuclear governance, particularly in managing naval nuclear fuel under the non-proliferation regime.
  • The AUKUS initiative does not exploit a loophole in the international safeguards system but rather adheres to its established rules, with nuclear naval propulsion being a permissible, though largely unregulated, area of nuclear activity.
  • Australia’s commitment to nuclear non-proliferation remains strong, with the country engaging transparently with the International Atomic Energy Agency (IAEA) and ensuring that its nuclear activities, even for naval propulsion, will remain under appropriate safeguards.
  • Nuclear stewardship is central to Australia’s approach, with significant investments in regulatory frameworks, nuclear knowledge, and best practices for the safe and responsible operation of nuclear-powered submarines.
  • Australia’s acquisition of SSNs is setting a normative precedent as the first instance of a non-nuclear-weapon state using provisions under the safeguards regime to manage nuclear materials for non-explosive military purposes.
