It’s too early to say how long this shutdown of the Point Lepreau nuclear plant will last, site vice-president Joel Armstrong says. (Submitted by N.B. Power)
The Point Lepreau Nuclear Generating Station is shut down again, this time because of a heavy-water leak on an instrumentation line.
The line is part of the heat transport system, which is part of the heavy water station at the plant, Joel Armstrong, the deputy site vice-president at Point Lepreau, said in an interview.
Last week, there was an indication of a problem, he said, and the early indication systems worked exactly as planned, “allowing us to conduct a safe and predictable shutdown to facilitate the work.”
Heavy water carries heat from the reactor out to conventional boilers filled with regular water, creating steam to run the plant turbines.
