The definitive agreements include prepayments for future HALEU deliveries and finalize a letter of intent the companies signed in June, Oklo said. The purchases are backed by a prepayment from Meta Platforms for power production at Oklo’s planned 1.2-gigawatt campus in Ohio.

Oklo expects the fuel to support up to five of its Aurora powerhouses for several years. Chief Executive Jacob DeWitte said the contracts would serve the company’s initial Ohio deployments and provide fuel for future Aurora units.

“Meta’s support helps advance fuel procurement for the Ohio campus and our work to deliver new, clean, reliable power to the grid,” DeWitte said.
