When I first heard about these small scale reactors 10+ years ago I remember the goals were to build them to be maintenance-free and disposable. They build a self contained unit that needs minimal labor to run, is highly failsafe, and pumps out ~50Mw for roughly 20 years. When it's done they drop the whole unit (roughly the size of a train car) into a concrete grave onsite and plug in a replacement.

I'm not sure if the goals for this project are the same, or if the goal of a low-maintenance reactor are even possible, but it sounded pretty cool.
