Russia withdraws from the plutonium agreement signed with the United States

The lower house of the Russian parliament approved on Wednesday a withdrawal from a landmark deal with the United States that aims to reduce vast stocks of weapons-grade Plutonium leftover from thousands of Cold War nucleotide warheads.

In 2000, the Plutonium Management and Disposition Agreement, or PMDA, was signed by both Russia and the United States. This agreement committed them to dispose of a minimum of 34 tonnes each of weapons-grade Plutonium, which U.S. officials estimated would be enough for up to 17,000 nuclear bombs. It was signed in 2011.

A Russian note about the legislation that would withdraw Moscow from the agreement stated that "the United States has taken new anti-Russian measures that fundamentally alter the strategic balance at the time the Agreement was signed and create additional risks to strategic stability."

After the Cold War, Moscow and Washington had huge stocks of weapons-grade Plutonium that were expensive to store and could pose a proliferation risk.

The PMDA aims to eliminate weapons-grade plutonium through the conversion of it into safer forms, such as MOX fuel or irradiating the plutonium using fast-neutron nuclear reactors.

In 2016, Russia suspended the implementation of the agreement citing U.S. sanction and what they deemed as unfriendly action against Russia, NATO expansion and changes in the United States' disposal of plutonium.

Russia claimed at the time that Washington had violated the agreement by merely diluting and disposing the plutonium without Russian approval.

According to the United Nations, Russia and the United States control 8,000 nuclear weapons, a far cry from the 73,000 nuclear warheads they had in 1986.
