RE: [cdn-nucl-l] Pickering Not There
Yes, it makes sense to shut the two Pickering A
units, given that a safety-related issue was evidently identified.
Nuclear operators do not shut down without justification, and the
newspaper articles are too brief to explain the full story.
According to OPG http://www.opg.com/news/releases/NewsJul06_07.pdf
"While the Pickering A Units had been operating well, OPG's
decision-making adheres to a strict safety culture which dictated the
Units remain off-line while modifications to this backup system are
completed. The modifications are expected to be completed throughout
As an aside, I cycled on the waterfront trail
around Pickering, last Saturday. A really great trail, with a lovely
boardwalk and "seafront" feel, with protected marshland on the land
side of the trail.

The story says that two units at Pickering are not
running so their
backup systems can be maintained.
Does this make sense? If you operate without a
backup that means that
at least you are operating. Shutting down when the
backup is not there
makes the backup a liability, not a reliability
guarantee. If the story
is right, then the approach being followed at
Pickering does not seem
very practical to me. What is even worse, this
approach is being used
on two reactors concurrently. If they were both
running without a
backup and one failed at least we would have one still
running. As it
is we have none.
