Nuclear station overhaul still delayed

The much-delayed refurbishment of the Point Lepreau Nuclear Generating Station in New Brunswick has been in the news again.
The province’s energy minister, Jack Keir, has written to the federal government complaining that Atomic Energy of Canada Ltd. (AECL) is not keeping it informed about the extent of the delays. The federal government is a shareholder in AECL, which is the main contractor on the refurbishment.
This is the first refurbishment of a Candu-6 reactor, and according to a CBC report AECL had hoped it would be a model it could use to sell to other countries.
However, the $1.4 billion refurbishment is about 18 months behind schedule. Current delays are with installing the calandria tubes, 7-metre tubes that enclose the nuclear bundles within the reactor.
Once the reactor is refurbished it is supposed to be good to go for 30 years.
