100 kW may make sense but as part of a large facility with maybe a few hundred of them. Distributing nuclear material so widely would be imprudent. The materials themselves are dangerous, there's no getting around that and there's real value in a minimum of centralization and control of the reactors in one place. A turbine generating half a gigawatt is also much more efficient (orders of magnitude) than 5000 turbines generating 100kw.
