This is basically a Slowpoke3 reactor, modified to generate power through a sodium heat transfer instead of the boiled water originally envisaged. Check out www.nuclearfaq.ca - "In the early 1980's AECL developed a higher-power variant of this technology, called SLOWPOKE-3, which could act as a district heating source for remote communities. Such locations are often heated with networked hot-water systems that require a constant fossil-fuel supply." BTW burning coal releases far more radiation into the atmosphere per kWH than any nuclear power plant. Check it out
