Oklo, the advanced reactor developer previously chaired by Energy Secretary Chris Wright, was up more than 20% since Friday afternoon. Oklo's shares got another boost Tuesday morning as it announced a design and development partnership with Korea Hydro & Nuclear Power to accelerate deployment of its Aurora powerhouses.

Shares of small modular reactor developer NuScale and uranium suppliers Centrus Energy and Uranium Energy also rose more than 20% in Friday and early Tuesday trading.

Trump's "Reinvigorating the Nuclear Industrial Base" executive order called on Wright and other cabinet secretaries to develop a national policy for spent nuclear fuel management. The order singles out recycling and reprocessing activities that could benefit companies like Oklo, which plans to build fuel reprocessing capabilities and is developing reactors that can run on recycled fuel.

Another order, "President Donald J. Trump Deploys Advanced Nuclear Reactor Technologies for National Security," calls on Wright "to release at least 20 metric tons of high-assay low-enriched uranium into a readily available fuel bank for private sector projects operating nuclear reactors to power AI infrastructure at DOE sites." 

Congress last year banned Russian uranium imports from 2028, cutting off a key supply of HALEU in particular and adding urgency to ongoing federal efforts to expand domestic supplies. 

"Reinvigorating the Nuclear Industrial Base" also calls for the DOE Loan Programs Office to prioritize support for construction of new large reactors and 5 GW of power uprates to existing reactors by 2030. It specifically mentions support for "completing construction of nuclear reactors that was prematurely suspended," signaling possible LPO support for the completion of the two unfinished AP1000 reactors at Santee Cooper's VC Summer site in South Carolina.

Recent changes at DOE could undermine that goal, Nuclear Innovation Alliance President and CEO Judi Greenwald said in a statement.

"Recent DOE staffing reductions and proposed budget cuts undermine the Department's efforts and make it harder to implement these executive orders," Greenwald said. "We urge the Administration and Congress to adequately resource and staff DOE to meet this moment."

Greenwald said proposed NRC process changes in another executive order, "President Donald J. Trump Directs Reform of the Nuclear Regulatory Commission," while well-intentioned, could also prove counterproductive. 

"NIA has long thought it is important that NRC improve the efficiency of its activities," she said. "However …[o]ur assessment is that NRC is already making significant progress on reform in compliance with congressional direction including the 2024 ADVANCE Act. It is in everyone's interest that this progress continue and not be undermined by staffing cuts or upended by conflicting directives."
