Bruce Power’s Unit 6 Major Component Replacement (MCR) reached another important milestone.
Bruce Power reports the final of eight steam generators was lifted into place on December 18, safely and event-free.
Unit 6 contains eight steam generators which are arranged vertically in two columns of four on the east and west side of the reactor.
Each steam generator weighs approximately 320,000 pounds and was lifted through the powerhouse roof enclosure using Mammoet’s PTC-35 crane.
The 1,600-ton capacity crane is one of the largest in the world and features a boom the length of a hockey rink that can stretch over the station, which is seven storeys tall, and reach the inner-most steam generators.
The new steam generators were fabricated at BWXT in Cambridge and shipped to site in late 2020.
“These new steam generators will be in service for many decades providing clean, reliable power to Ontario homes and businesses,” said Eric Chassard, Bruce Power’s Executive Vice President, Projects & Engineering. “This is a culmination of many years of hard work and collaboration between Bruce Power and our partners like SGRT, BWXT, Mammoet, Nuvia and the Building Trades Unions."
