PITTSBURGH, April 3, 2003 — PCI Energy Services, a subsidiary of Westinghouse Electric Company LLC, working with Bechtel Power Corporation, established a new world record for the shortest Reactor Coolant System (RCS) Window.
The new record time for severance and reconnection of the Reactor Coolant System for a four-loop steam generator replacement project is now set at 35 days, five hours at the South Texas Project (STP) Unit 2 in Matagorda County, Texas. This new world record follows another recent PCI world record at Tihange 2 in Belgium.
Each of the four replacement steam generators weighed more than 500 tons, were 72 feet high and 16 feet wide. The RCS Window record played an important role in setting STP Unit 2’s world record for the overall outage schedule of 65 days. These shorter outages are an important financial factor to nuclear utilities in today’s electrical power marketplace.
PCI was the source for the important processes of laser templating, machining and welding for the replacement of the nuclear reactor’s steam generators. John Qualizza, vice president, PCI Projects, commended the project team’s efforts, led by Scott Achtor and Project Manager Ken Nance. “This was a tremendous effort by PCI experts in remote machining, welding and metrology, and by the support trades from the United Association of Plumbers and Pipe Fitters Local 211 of Houston, Texas,” said Qualizza.
Qualizza was also particularly complimentary of the cooperation between Westinghouse and Bechtel Power Corporation and their contractors, as well as the efforts of the unit’s operator, STP Nuclear Operating Company. According to STP Nuclear Operating Company, the project set a new performance standard for the nuclear industry and was a big success for PCI, Westinghouse, Bechtel and STP.
PCI, headquartered in Lake Bluff, Illinois, has remained at the forefront of field machining and welding for 32 years and specializes in remote applications, including engineering tool design, laser metrology, and quality assurance and control.
Westinghouse Electric Company, wholly owned by BNFL plc of the United Kingdom, is the world’s pioneering nuclear power company and is a leading supplier of nuclear plant products and technologies to utilities throughout the world. Today, Westinghouse technology is the basis for approximately one-half of the world’s operating nuclear plants.
