Electro-Mechanical Division began its' association with nuclear power in the 1952 with they development of critical function pumps for the propulsion (power) system install on the USS Nautilus (the U.S. Navy's first nuclear power submarine).In 1957 when President Eisenhower gave his famous speech "Atoms for Peace" to the United Nations and launched the era of nuclear power EMD was well positioned to play a significant role in the design of the first Westinghouse large-scale nuclear power plant at Shippingport, PA. Today they continue to supply critical equipment to operating reactors as well as provide repair, refurbish, remanufacturing, engineering and testing services to the nuclear power industry. 

	EMD Reactor Coolant Pumps The AP1000 Reactor Coolant Pump is based on technology that is currently operating in other power plant applications. The longest running canned motor pump has operated for over 40 years at Mitchell Generating Station in Pennsylvania.     Design philosophy The AP1000 pump design philosophy is the same as utilized on all EMD canned motor pump designs Stainless steel cans protect the motor rotor and stator from the operating fluid No shaft seals Water lubricated bearings operating with no wear     Additional features Sixty year life with no maintenance Flywheels to provide the inertia based on plant coast-down requirements These will be the largest canned motor pumps that EMD has ever designed and manufactured.
	EMD Control Rod Drive Mechanisms (CRDMs) Control Rod Drive Mechanisms (CRDMs) are utilized to control the level of reactivity in the reactor core. EMD has over 45 years of design and manufacturing experience withered. There are more than 5,000 CRDMs operating in 88 plants worldwide that EMD designed and manufactured. The latest design is qualified for 7 million steps (similar in concept to the movement of a ball point pen) and 40 years of operation. EMD has over 40 years of successful operation with operating availability greater than 99.9%. Discover more about EMD.
