X-energy has developed the Xe-Mobile – a power generation system that can be delivered to the point of electricity need and quickly begin generating power. Features of the Xe-Mobile include:

• Rail, truck, and sea transport compatibility
• Components housed cargo containers
• Can operate at full power for more than 3 years
• Utilizes TRISO fuel, due to high maturity & a strong safety case
• Produces 2-7 MWe of electrical power
• Multiple voltage outputs available

BWXT is building the first 1-5 Megawatt Pele micro nuclear reactor design and it will be completed in 2024, fueled and operational in 2025. In July, 2023, BWXT was also selected to supply the nuclear reactor and fuel for the DRACO nuclear thermal rocket (formally known as the Demonstration Rocket for Agile Cislunar Operations). The DRACO nuclear thermal rocket is to be launched into orbit by 2026 on a regular chemical rocket. It would then provide propulsion in orbit. Miller said that BWXT is renovating a 170,000-square-foot building that will host both DRACO and Pele during assembly.

DOD's Strategic Capabilities Office (SCO), US Department of Energy, the Nuclear Regulatory Commission (NRC) and the US Army Corps of Engineers, as well as with industry partners are working together on this. DOD's Strategic Capabilities Office awarded a $300 million contract to BWXT to complete and deliver a full-scale transportable high-temperature gas-cooled microreactor prototype in 2024 for testing at the Idaho National Laboratory. Design approvals were made by the Department of Energy and the NRC.

The US Navy has nearly 100 nuclear reactors. All US submarines (about 71) are nuclear powered and 11 aircraft carriers (and two more under construction) each have two nuclear reactors. There are five more with three moored training ships (MTS) and two land-based training plants.
