![]() ![]() Under this Russia would convert 500 tonnes of HEU from warheads and military stockpiles (equivalent to around 20,000 bombs) to LEU to be bought by the USA for use in civil nuclear reactors. Surplus weapons-grade HEU resulting from the various disarmament agreements led in 1993 to an agreement between the US and Russian governments. Megatons to Megawatts, the Russian HEU dealĬommitments by the USA and Russia to convert nuclear weapons into fuel for electricity production was known as the Megatons to Megawatts program. Military plutonium can blended with uranium oxide to form mixed oxide (MOX) fuel.Īfter LEU or MOX is burned in power reactors, the spent fuel is not suitable for weapons manufacture. World stockpiles of weapons-grade plutonium are reported to be some 260 tonnes, which if used in mixed oxide fuel in conventional reactors would be equivalent to a little over one year's world uranium production. * according to TradeTech: Russia 720 t +/- 120 t, USA 600 t. Highly-enriched uranium in US and Russian weapons and other military stockpiles amounts to about 1500 tonnes*, equivalent to about seven times annual world mine production. It is blended with depleted uranium (mostly U-238), natural uranium (0.7% U-235), or partially-enriched uranium. HEU can be blended down with uranium containing low levels of U-235 to produce low-enriched uranium (LEU), less than 5% U-235, fuel for power reactors. ![]() The main weapons material is highly enriched uranium (HEU), containing at least 20% uranium-235 (U-235) and usually about 90% U-235. A 1993 agreement covered essentially the enrichment component of this material, but left unresolved the question of feed from mines, and a 1999 agreement dealt with what happened to the feed material. ![]() With the disintegration of the Soviet Union, a unique opportunity arose to deploy military weapons material for making electricity. Nuclear materials declared surplus to military requirements by the USA and Russia have been converted into fuel for commercial nuclear reactors. Since 1987 the United States and countries of the former USSR have signed a series of disarmament treaties to reduce the nuclear arsenals by about 80%. This gave way to a focus on the role of military uranium as a major source of fuel for commercial nuclear power. Highly-enriched uranium from weapons stockpiles has been displacing some 8850 tonnes of U 3O 8 production from mines each year, and met about 13% to 19% of world reactor requirements through to 2013.įor more than five decades, concern has centred on the possibility that uranium intended for commercial nuclear power might be diverted for use in weapons.Weapons-grade plutonium has over 93% Pu-239 and can be used, like reactor-grade plutonium, in fuel for electricity production. Weapons-grade uranium is highly enriched, to over 90% U-235 (the fissile isotope).Weapons-grade uranium and plutonium surplus to military requirements in the USA and Russia is being made available for use as civil fuel.All rights reserved.Military Warheads as a Source of Nuclear Fuel ™ & © 2021 Cable News Network, Inc., a WarnerMedia Company. This story has been updated with additional details Wednesday. According to data released in 2015, the US had 4,717 nuclear warheads in the stockpile as of September 2014. ![]() In 2010, the Obama administration revealed the US had 5,113 nuclear warheads in the stockpile as of September 30, 2009. Two thousand nuclear warheads are retired and waiting to be dismantled, the department also said. The US also dismantled 11,683 nuclear warheads from 1994 to 2020, including 711 nuclear warheads since September 30, 2017. In Tuesday’s release, the State Department said there are 3,750 nuclear warheads in the US nuclear stockpile as of September 2020, an 88 percent decrease from its maximum number of 31,255 in 1967, according to the department. policy and seek new risk reduction and arms control arrangements with Russia and perhaps China.” The ACA called Biden’s budget request inconsistent with his “stated desire to reduce the role of nuclear weapons in U.S. “So what the Biden administration is trying to do here is lead by example,” Kimball said, “put some pressure on the other major nuclear armed countries to be more forthcoming about the nuclear weapons they have.”ĭuring the 2020 presidential campaign, then-candidate Joe Biden said that the US doesn’t need new nuclear weapons and that his “administration will work to maintain a strong, credible deterrent while reducing our reliance and excessive expenditure on nuclear weapons.”Īfter Biden’s first budget request, however, critics rapped the President for proposing to continue all parts of the spending plans left by the Trump administration, including “the controversial additions made by President Trump to the Obama-era program, such as additional, more usable lower-yield nuclear capabilities,” the ACA said. ![]()
