We built this for you, our Pickering #CANDU π¨π¦ Nuclear Plant.
Even back in the environmental dark ages, we knew it was a much better choice than a coal fired plant. Clean #nuclearenergy for everyone, for Toronto, for Ontario, for Canada, for the future.
Then it was your turn.
As Pickering B reached its 30-year theoretical limit of pressure tube life in 2006, you started a project for mid-life refurbishment.
Good move.
The OPG process made its way though a CNSC environmental assessment & preliminary plans were developed.
We now know the reasoning for the decision. It should be said no defects were cited, only a series of risks, some of which now appear somewhat dubious.
We know that. That's why the post per unit energy cost will be higher. The reasons Pickering B units were built this way, while being the same vintage as Bruce B, have been covered several times in the past.
β’ Pickering B units donβt meet modern standards
From what we know, Pickering B safety systems meet modern standards, same as any CANDU 6. A statement in the briefing note is misleading. It seems to be based on Pickering A.
β’ Shutdown would have impact on OPG fleet to meet power demands
β’ Shutdown would interfere with plans to refurbish Darlington
OPG decided to dump Pickering to protect the Darlington refurbishment, & probably new build plans. Fortunately, they kept it running on extended life.
β’ Pressure tube life is 30 years
Continued operation of Pickering B, & Bruce B for that matter, have demonstrated that 30 years was wrong. We are now looking at life of 40 years or more, which significantly improves the economies of scale.
β’ Pickering B units retain significant risk of less-than-optimal performance.
Even in their current extended operation state, performance has continually improved. With a refurbishment, including uprates, performance can improve even further.
I am curious, only a weather hobbyist, but apply my auditing background in my search for FACTS. I was preparing some #climate info yesterday for posting this morning & was greeted by some other posts today which complement my looking at indicators of #climatechange exaggeration.
The world's weather stations, according to @TempGlobal, continue to show that the global climate is maintaining it's recent cooling trend. #climatechange#GlobalWarming
