    Bruce Power has brought reactors back online previously laid-up for refurbishment.  All units are working today, the first time since 1996, bringing the total up to 5,500MW of low-cost juice to the grid (with 8 reactors operating it is now the largest nuke facility in the western hemisphere).  Thanks to Bruce Power and 8 more CANDU units up at Pickering and Darlington, Ontario's grid is currently running 91% CARBON FREE at the time of writing (65% nuclear, 23% hydro and 3% wind).  

    THAT is how we celebrate Earth Day here in Ontario, with work that actually DELIVERS results in slashing emissions with a nearly zero-carbon grid! We now have to do something about Alberta's emissions re tar sands...

    The intrinsic nature of Power is such that those who seek it most are least qualified to wield it.

      the Nanticoke coal plant used to be one of the worst polluters in North America.

      energy with all the money those CANDU reactors sucked up:

      "Based on Ontario's record, the economic performance of the CANDU system is quite poor. Although much attention has been focussed on the problems with the Darlington plant, in fact, every single CANDU design in Ontario went over budget by at least 25%, and average over 150% higher than estimated.[61] Darlington was the worst offender, at 350% over budget, but this project was stopped in-progress thereby incurring additional interest charges during a period of high interest rates, which is a special situation that was not expected to repeat itself.

      In the 1980s, the pressure tubes in the Pickering A reactors were replaced ahead of design life due to unexpected deterioration caused by hydrogen embrittlement.

      All the Pickering A and Bruce A reactors were shut down in 1999 in order to focus on restoring operational performance in the later generations at Pickering, Bruce and Darlington. Before restarting the Pickering A reactors, OPG undertook a limited refurbishment program. The original cost and time estimates based on inadequate project scope development were greatly below the actual time and cost and it was determined that Pickering Units 2 and 3 would not be restarted for commercial reasons. Despite this refurbishment, the reactors have not performed well since the restart.
      These overruns were repeated at Bruce, with Units 3 and 4 running 90% over budget.[61] Similar overruns were experienced at Point Lepreau,[62] and the planned refurbishment of the Gentilly 2 plant has been delayed until the fall of 2012, and currently there are serious plans to simply shut it down instead."
