Westinghouse's heat-pipe reactor theoretically outputs respectable power compared to larger reactors using light water, heavy water, or both, to cool the fission core. To scale this tech down to a form factor that fits on the back of an 18-wheeler trailer is a feat within itself. //

At its core, the eVInci heat pipe microreactor almost resembles a large gas canister more so than it does a mobile power generating station. Inside this large metal cylinder, nuclear fuel rods of particularly high quality are arranged into a compact but powerful fissile core with large metal heat transfer pipes running through the core's center. The fuel in question is known as Tri-structural isotropic particle fuel, or TRISCO for short. It consists of a proprietary blend of Uranium isotopes mixed with carbon and oxygen to form a fuel kernel the size of a poppy seed.

These highly enriched and energy-potent fissile fuel pellets can theoretically remain critical without the need for refueling for up to eight years. At this point, the whole device can be packed into a shipping container and sent back to Westinghouse's facility in Cranberry Township, Pennsylvania, for proper disposal of spent nuclear fuel rods. On top of that, Westinghouse reckons it's possible to install an eVinci power station in as little as 30 days. //
