Russia Withdraws from Plutonium Disposal Agreement with the U.S.

On October 8, 2025, Russia’s lower house of parliament (State Duma) approved a proposal to withdraw from the Plutonium Management and Disposition Agreement (PMDA) — a landmark arms-control pact with the United States that sought to reduce stockpiles of weapons-grade plutonium left over from the Cold War.

🔹 About the PMDA Agreement

• The Plutonium Management and Disposition Agreement (PMDA) was signed in 2000 between the U.S. and Russia.
• It came into force in 2011.
• Under the agreement, both nations committed to dispose of at least 34 tonnes of weapons-grade plutonium each — an amount sufficient for around 17,000 nuclear warheads, according to U.S. officials.

🔹 Objective of the Agreement

• The PMDA was designed to minimise nuclear proliferation risks and promote safe disposal of excess plutonium.
• It aimed to convert the weapons-grade plutonium into safer forms, such as:
  • Mixed Oxide (MOX) fuel, to be used in nuclear reactors, or
  • Irradiation in fast-neutron reactors for electricity generation.

🔹 Background and Suspension

• After dismantling thousands of nuclear warheads following the Cold War, both Moscow and Washington were left with large plutonium stockpiles that were costly to maintain and posed a security risk.
• In 2016, Russia suspended implementation of the PMDA, accusing the U.S. of:
  • Imposing sanctions and taking “unfriendly actions” against Russia,
  • Supporting NATO expansion, and
  • Altering its plutonium disposal methods, which Russia argued violated the spirit of the agreement.

🔹 Current Development

• The formal withdrawal marks another step in the deterioration of arms control cooperation between the world’s two largest nuclear powers.
• Analysts warn that this move could further weaken global non-proliferation efforts and increase nuclear tensions amid strained U.S.-Russia relations.
