Arnprior, May 4, 2017 -- Nu-Tech Precision Metals is proud to announce that the first pressure tubes destined for Ontario Power Generation’s refurbished Darlington reactors have been completed and are now ready to ship to the Darlington site.

“Since 1957, every pressure tube in an operating CANDU reactor has been made by Nu-Tech,” said George Legate, Nu-Tech President. “We’re very proud to have been trusted to manufacture this very important component of these reactors.”

Nu-Tech was subcontracted by the SNC-Lavalin / Aecon Joint Venture to manufacture the 480 pressure tubes for each of the four reactors undergoing refurbishment at OPG’s Darlington site. Manufacturing began two years ago and has been completed eight weeks ahead of schedule. “Nu-Tech is a trusted partner,” said Preston Swafford, Chief Nuclear Officer and Executive Vice-President, Nuclear, SNC-Lavalin, on behalf of the Joint Venture. “We know we can count on this team in Arnprior to deliver this specialized nuclear component.”

Pressure tubes, made of zirconium are 6 metres long, with a diameter of 11 cm. They house the fuel bundles which contain natural uranium, the fuel for CANDU reactors.

“Our continued partnership with suppliers such as Nu-Tech reinforces the entire nuclear industry’s commitment to delivering Canada’s largest clean energy project on-time and on-budget,” said John M. Beck, President and CEO, Aecon Group Inc., on behalf of the Joint Venture. “We look forward to working on the next phase of this essential program.”

“The Darlington Refurbishment Project will not just provide 30 more years of clean reliable energy, the project and continued operations of the station is also helping power Ontario’s economy,” said Jeff Lyash, OPG President and CEO. “The Darlington Refurbishment is a made-in-Ontario project. Nu-Tech is one of many trusted companies from across Ontario directly engaged in the massive undertaking providing specialized expertise and quality materials.”  

The Darlington refurbishment project is a large part of Ontario's clean energy equation bringing energy to the province until 2055 and is Canada's largest clean energy project. The project remains on schedule and on budget and recently successfully completed the first of four substantial segments of the Unit 2 refurbishment by isolating Unit 2 from the rest of the generating station. The project and subsequent 30 years of station operation will generate a total of $89.9 billion in economic benefits for Ontario, including the preservation of approximately 3,000 jobs and an expected boost to personal income by an average of $1.6 billion per year.
