Naval Nuclear Propulsion program seeks continued funding for Columbia reactor development, spent‑fuel facility; Navy says reactors on schedule for submarine in‑

Summary
Admiral John (William) Houston told the Senate subcommittee Naval Reactors prioritizes people, R&D and infrastructure including reactor plant development for the Columbia‑class and a naval spent‑fuel handling facility in Idaho; Admiral said reactor plant is ready awaiting shipbuilder schedule and core production is progressing.
Naval Nuclear Propulsion witnesses told the Senate subcommittee they are prioritizing workforce, research and infrastructure to support the Columbia‑class ballistic missile submarine and that reactor plant components and fuel production are on track for delivery when ship construction requires them.
Admiral William Houston, director of Naval Reactors, said the program’s top priorities are people, research and modernizing critical infrastructure. He asked for continued congressional support for two national priority efforts: development of the Columbia‑class reactor plant and construction of a Navy spent‑fuel handling facility in Idaho. "I'm seeking your continued support for two national priority projects," he said.
Why it matters: The Columbia class is the Navy’s top acquisition priority. Reactor plants, reactor cores and spent‑fuel handling capabilities are necessary to outfit and sustain the class on schedule; delays in component delivery or in facilities that process naval spent fuel could affect submarine construction and availability.
Key program points - Houston testified the reactor plant for the Columbia class is under continued development and that the Navy’s reactor plant for the first Columbia hull is ready and being held for shipment to Electric Boat when the shipbuilder needs it; he stressed security and timing considerations. "My reactor for District Of Columbia is ready. It's just waiting to be shipped when Electric Boat wants it," he said. - The second reactor core was reported as roughly 75% complete; Houston said major plant equipment (steam generators, pressurizers, reactor coolant pumps) is on schedule and that port and starboard turbine generators are progressing with testing and packaging for shipment. - The Navy’s spent‑fuel handling facility in Idaho is under construction; Houston described ongoing challenges but said visible progress has occurred from multiple site visits.
Workforce and industrial base Houston and other witnesses emphasized the workforce as a critical resource. They described the need to maintain highly trained technical staff across Navy strategic systems and the nuclear propulsion enterprise. Witnesses told senators that sustaining specialized industrial suppliers and maintaining skills are key to avoiding schedule slips.
Related DOE work Naval Reactors relies on DOE infrastructure and NNSA for certain materials and facilities; witnesses discussed coordination across agencies to support both naval propulsion needs and the broader weapons complex recapitalization.
Ending note: Admiral Houston concluded by asking for continued, stable support to sustain investments in people, R&D and infrastructure that underpin naval nuclear propulsion and the Columbia‑class schedule.
