Dresser Consolidated Selected as Main Steam Safety Valve Supplier for Westinghouse Nuclear Reactors
Monday, November 22, 2010
Dresser Consolidated today announced it has been chosen by Westinghouse
Electric Company LLC as the main steam safety valve supplier for four of the
company’s AP1000 pressurized water reactors (PWR) in the United States.
The Dresser Consolidated 3700 Maxiflow main steam safety
valves will be delivered to AP1000 nuclear power plant sites in Georgia and
South Carolina between 2012 and 2014. The AP1000 reactor is the only Generation
III+ reactor to receive Design Certification from the U.S. Nuclear Regulatory
Commission.
The reactors are expected to come online starting in 2016.
By discharging steam to atmosphere, the 3700 main steam safety valves will
ensure residual heat removal from reactor coolant system via the steam generator,
and secondary side over pressure protection during design basis accidents and
transients.
"We are excited to be at the forefront of this endeavor and
partner with a technology leader such as Westinghouse to introduce the next
generation of nuclear power solutions back into the United States, said Nathan
Brunell, Vice President of Marketing, Flow Technologies, Dresser Inc. Dresser Consolidated’s
products and significant experience in nuclear valve design make us an ideal
partner to deliver safety valves for nuclear reactor applications and the
proven design and superior quality of 3700 valve making it the leading main
steam safety valve in the industry.”
Dresser Consolidated is one of few safety valve suppliers in
the world that can comply with the full scope of products and stringent
certifications required for the nuclear power industry. The 3700 Maxiflow main steam
safety valve is designed with a duel outlet configuration that can handle more
than one and a half million pounds per hour of steam. A Thermodisc seat design
offers a leak-tight interface between the nozzle and the valve disk. The 3700
Maxiflow main steam safety valve will also comply with QME-1 requirements and
flow test requirements mandated by the American Society of Mechanical Engineers.
