I was imagining something in a standard shipping container for quick install or swap out, and centralized construction, service and refueling. The dimensions discussed here, and the fast radiation decay to safe levels would make transport feasible.

Even if the energy recovery from excess heat ends up being a turbine housed in a separate container, (supercritical CO2?) the elements are small enough to be containerized. Although perhaps this portability makes the chance of outright theft somewhat harder to deal with.
