[en] A new concept for a power reactor in the 200/400MWe range is described. It makes use of proven components but is neither a scaled-down version of a large reactor nor a modified ship propulsion reactor. Safety is not comprised in this simplified BWR design. The approximate cost of electricity generation for a 200 MWe unit is DMO.02/KWh, therefore for 6000 full load hours/annum, the operating cost is DM24 million. When compared with DM130 million for an oil fired plant, the difference in annual cost is enough to offset the high capital cost of the plant. (U.K.)
