DescriptionABC-70-8883 Engineering assistant Tom Becknell inspects the turbine blades on one section of a 210-foot-long turbine generator installed at Commonwealth Edison Company's Dresden nuclear power station, near Morris, Illinois. Steam pushing on nearly 11,000 of these blades will spin the turbine at l800 revolutions per minute and generate over 800,000 kilowatts of electricity. The turbine-generator is part of the Dresden 3 nuclear unit being built for service in 1971. Credit: Commonwealth Edison Company
