US picks potential partners for using Cold War-era plutonium as fuel

The US Department of Energy selected five companies, including Oklo, for advanced talks about using surplus plutonium as nuclear reactor fuel. The plutonium is held at heavily guarded weapons facilities in states such as South Carolina, Texas, and New Mexico and requires protective handling due to its long half-life. Oklo plans to develop the fuel with newcleo, a European company focused on high-tech nuclear reactors. The plan follows a Trump order to shift from diluting and disposing surplus plutonium toward providing it for advanced nuclear technologies. Critics including Markey, Beyer, and Garamendi raised weapons proliferation concerns, arguing the amount could support thousands of nuclear bombs and could harm defense posture. Other selected firms include Exodys Energy, SHINE Technologies, Standard Nuclear, and Flibe Energy.

"The United States government has chosen five companies, including nuclear energy company Oklo, to enter advanced talks over potentially using its Cold War-era plutonium as a nuclear reactor fuel. The US Department of Energy made the announcement on Tuesday. The Energy Department holds surplus US plutonium, which has a half-life of 24,000 years and must be handled with protective gear, at heavily guarded weapons facilities in states including South Carolina, Texas and New Mexico."

"Oklo, whose stock price was up more than 5.5 percent to $69.51 per share, said it plans to develop the fuel with newcleo, a European company that aims to build high-tech nuclear reactors. The Reuters news agency reported last year that the administration of US President Donald Trump plans to make about 20 metric tonnes of plutonium from dismantled nuclear warheads available to US power companies."

"Last May, Trump ordered the halt of much of a programme to dilute and dispose of surplus plutonium, and instead provide it as a fuel for advanced nuclear technologies, a plan that some Democrats opposed. In a letter in September, Senator Edward Markey of Massachusetts and Representatives Don Beyer of Virginia and John Garamendi of California said that 20 metric tonnes of weapons-usable plutonium was enough for approximately 2,000 nuclear bombs. Such a move raises serious weapons proliferation concerns, makes little economic sense, and may adversely affect the nation's defense posture, they wrote, asking the agency to cancel the plan."

"The other companies selected are privately held Exodys Energy, SHINE Technologies, Standard Nuclear and Flibe Energy, the US Energy Department said in a statement. Oklo said in a statement that newcleo would bring fuel experience and potential project capital, subject to agreements, approvals and US security and safeguards"
