Summary

Bobby Gallagher discusses Deployable Energy's Unity nuclear battery — a 1 MW micro-reactor designed for mass manufacture and distributed deployment.

Key Points

  • Reactor design: LEU (5%) UO2 fuel, light water moderated, helium cooled (~50 bar), pressure tube design
  • Size advantage: Light water moderation enables core size of "a couple feet" vs 8 feet for graphite — 25x power density advantage
  • No operator required: Load following via helium blower speed; remote control capable; E-stop for emergencies
  • Transport demo: Reactor vessel shipped Houston→Idaho in an F-150 pickup; criticality target before July 4
  • Factory: 58-acre, 340,000 sq ft facility in Houston; mass manufacture philosophy (no open die forgings)
  • Business model: Hybrid gas-to-nuclear transition; maritime; islands (Fiji: 10-12% GDP on diesel, $400-1000/MWh)
  • DOE Nuclear Energy Launchpad: One of four companies selected; testing at INL + first maritime demo + self-powered factory
  • Fuel: Standard PWR-compatible, DOE contract, 69-day manufacturing lead time
  • Spent fuel: Expects economic fuel cycle closure within 5-10 years
  • Bobby's background: Australian, 4th-gen military (IED countermeasures), Diamond Offshore, VC-backed exit
