Remote locations need independent power supply. Diesel generators (the only practical alternative) need a constant supply of fuel, with on site bulk storage. The military have a 50 year history of operating small reactors, and US/UK ones have an exemplary safety record. Nuclear power generator fuel isn't weapons grade (although it could be used in a dirty bomb, but attacking a base with the object of extracting and transporting away such material sounds a formidable challenge to potential undesirables).
It sounds like an idea worth a feasibility study.
