Although they were comparable in power to the Shippingport Atomic Power Station, the Soviet planners regarded the Beloyarsk reactors as prototypes.[2] Their main novelty was the use of superheated steam ran through a standard turbine thus resulting in a better efficiency compared to the earlier Obninsk Nuclear Power Plant pilot plant. The first Beloyarsk unit produced about 285 MW heat of which about 100 MW were converted to electricity.[2] The second unit, which used two turbines, had a similar conversion efficiency of about 36%.[2]
