Dresser Consolidated announced it has been chosen by Westinghouse Electric Company as the main steam safety valve supplier for four of the company’s AP1000 pressurised 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 US Nuclear Regulatory Commission according to the company.
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,” he added.
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, according to the company.
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.
