Each plant is supported by two AP1000 reactors, while each reactor holds four reactor coolant pumps. Each RCP weighs 200,000 lbs. Curtiss-Wright Corp. (NYSE: CW), Westinghouse Electric Co. and State Nuclear Power Technology Corporation of China (SNPTC) completed testing of a nuclear reactor coolant pump (RCP). such as the flow rate, speed, and head of the reactor coolant pump are all nonlinear changes. The AP1000 PWR uses extensively analyzed and tested passive safety systems to improve the safety of the plant. The RUV is a very compact, vertical pump/motor unit, designed to fit into the compartment next to the reactor pressure vessel. Each AP1000 includes four of the sealed reactor coolant pumps, which have had design and quality problems before. 5.7 RO-AP1000-20. "Conclusion of the reactor coolant pump testing program is a major milestone in the delivery of the world's first AP1000 plant. This provides the required increase in reactor coolant flow with only a small increase in the physical size of the canned motor. Curtiss-Wright performed qualification of the RCP at its Flow Control business segment’s electromechanical division facility in Cheswick, Pa. The final performance testing has verified successful reactor coolant pump operation during a full range of AP1000 plant operating conditions … The pump is designed, manufactured and tested by Curtiss-Wright Corporation at its Flow Control segment’s Electro-Mechanical Division (EMD) facility in Cheswick, Pennsylvania. To begin the description, let us first see the configuration of the AP1000 reactor primary coolant system shown in Figure 4. Each AP1000 employs four main reactor coolant pumps, which circulate reactor coolant through the core, loop piping and steam generators. Curtiss-Wright has learned that one of the four reactor coolant pumps located at the Sanmen 2 reactor in China unexpectedly tripped and shut down upon the detection of a reactor coolant pump fault. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Brief Description of the change (what is being changed and why): This report summarizes changes to the AP 1000 reactor coolant pump design which have resulted from detailed design work. It is a hermetically sealed, wet winding motor pump. There are four AP1000 reactors under construction in China and four in the United States. Subscribe to … ... Georgia Power also announced the first reactor coolant pump (RCP) at unit 3 had successfully been started up, verifying the pump operates as designed. The RUV is a reactor coolant pump, specially designed for the Westinghouse AP1000 reactor. Cooling systems naturally ensure a heat transfer from a reactor core to steam generators, which is the main purpose of the cooling systems. The pump weighs 187.5 tons, or 375,000 pounds, and is a critical component of the AP1000 design as it circulates hot primary-circuit water within the reactor. Minimum net positive suction head requirements are not required to provide safe operation of the AP1000. The pump being redesigned is a reactor coolant pump manufactured by the EMD division of the Curtiss-Wright company. Curtiss-Wright Flow Control - EMD and Westinghouse Electric Company LLC say they are continuing testing of the world's largest canned-motor reactor coolant pump (RCP) for the AP1000. The RUV is a very compact, vertical pump/motor unit, designed to fit into the compartment next to the reactor pressure vessel. 2 reactor in November, it has since been suspended after a problem with its coolant pump was detected near the end of last year. The System 80 design was created by Combustion Engineering and featured a two-loop cooling system with a single steam generator paired with two reactor coolant pumps in each loop that makes it simpler and less expensive than systems which pair a single reactor coolant pump with a steam generator in … The Westinghouse AP1000 plant is a two-loop design in which there are four cold legs and two hot legs. The coasting characteristic of the reactor coolant pump is an important indicator for the safe operation of the nuclear power system.
