Navy's Crane Indiana Microreactor Brings Zero Manufacturing Jobs to the State
The Department of the Navy selected Radiant Industries on October 20 to build the Kaleidos microreactor at Naval Support Activity Crane in Martin County, the Navy's first shore-based power reactor since it shut down a trouble-plagued unit in Antarctica in 1972. The 1-megawatt reactor ships inside a 35-foot container, weighs about 70 tons, runs on TRISO fuel and helium cooling, and is built to run five years between refuelings. Radiant owns and operates the unit under its existing $750 million, 15-unit allocation from the Army's Janus Program, so Crane isn't a new contract. It's a draw against a fixed pool that also has to cover Radiant's anchor deployment at Fort Benning, Georgia. This is Indiana's first power reactor of any kind, the state's only other reactor is a 12-kilowatt teaching unit in a Purdue basement. None of the fueling or refueling work happens here. Both occur at Radiant's factory in Oak Ridge, Tennessee, which means the manufacturing content tied to this project stays in Tennessee while Crane just buys the power.
- Impact
- This is Indiana's first power reactor of any kind (the state's only existing unit is a 12-kilowatt teaching reactor in a Purdue basement) and the Navy's first shore-based power reactor since it shut down a plagued 1.8-megawatt unit at McMurdo Station, Antarctica, in 1972 after 438 malfunctions. The bigger story is a two-track regulatory setup nobody's flagged: the Army authorizes Janus reactors like this one directly, bypassing NRC review, while Radiant's commercial units for data-center customer Equinix still need NRC sign-off, and Radiant's Oak Ridge factory has no licensed storage pathway yet for spent TRISO cores, meaning the fuel is still unresolved at the back end. Because Crane draws down Radiant's fixed 15-unit allocation, every new base added compresses what's left for Radiant's three-unit anchor deployment at Fort Benning.
- Watch
- The NRC's accelerated 8-month review of Radiant's R-50 Part 70 license application in Oak Ridge, Tennessee, the single regulatory gate that could delay the 2028 delivery target for all three military services.
- For the huddle
If the reactor arrives factory-fueled and goes back to Tennessee for refueling, is there any realistic entry point for an Indiana supplier into the TRISO fuel, helium-cooling, or microreactor-container supply chain, or does this stay a pure power-purchase deal with zero local manufacturing upside?
Start with KTR's hydraulic component line rather than its wind coupling business, since the coupling side carries real substitution risk from direct-drive turbines and the hydraulic side doesn't. The Crane reactor itself offers nothing locally, fueling and refueling both happen at Radiant's Oak Ridge, Tennessee factory, so don't plan around any local content there.
