Bruce Power cut into the roof of an operating nuclear station, hauled eight steam generators weighing 100 metric tons each (about 110 US tons) out through the top, and lowered brand-new ones into the same hole. Then it brought the reactor back online on June 8, according to Bruce Power, seven months ahead of schedule.
I was picturing some burly Aussie-Canadian lumberjack called Bruce Power doing all this without breaking a sweat.
