Advanced Reactors

X-Energy reported a $104 million operating loss for Q3 2026 and increased cash use while advancing DOE-supported reactor work. DOE’s cooperative agreement provides up to $1.2 billion in cost-share reimbursement, with approximately $618 million reimbursed by September 30; future funding depends on approvals and appropriations, and no active procurement is identified.

DARPA’s Fat Cat program is developing and testing autonomous controls and physics models for small fast reactors intended for remote environments, including space and undersea settings. While a social media post claims SpaceNukes received an award, the available program information does not verify an award, its value, or any related contract details.

The Department of Energy seeks private sector partners to advance nuclear fuel recycling through two new RFAs. This initiative aims to enhance U.S. energy independence and promote innovative recycling technologies, presenting substantial opportunities for contractors specialized in this area.
