For smaller cities with populations from around 130,000 up to 400,000 a ship with a single SMR is deployed.
The SMR (I) is designed to operate year-round in CHP mode raising steam (II) to produce electricity via a non-condensing turbine + generator (III, IV) and using the low pressure exhaust steam to heat a district-heating water circuit (V). Any surplus heat in the form of uncondensed steam is removed by the on-board supplementary condensers (VIII) and the cooling circuit (IX) for these is cooled, in turn, by water drawn from the estuary (X). Hot condensate from the hot well (VII) is pumped (VI) back through the boiler (II) to complete the closed-loop steam circuit.
