Oklo experienced a significant pre-market surge of 12% on Tuesday. The advanced fission power plant developer saw its shares rally in early trading following a major business development announcement.

The sharp upward movement appears to be directly linked to company-specific news. Oklo announced it has been selected by the US Energy Department for advanced talks regarding the use of Cold War-era plutonium for nuclear reactor fuel. This development represents a potential advancement for Oklo's nuclear fuel recycling technology, which converts nuclear waste into usable fuel for its reactors.

The selection for these high-level discussions with a key government agency signals growing recognition of Oklo's technology and could potentially open new avenues for the company's clean energy solutions. Investors reacted positively to this news, driving the stock higher in pre-market trading activity.
