http://www.thestar.com/Business/article/237947A third reactor at Pickering generating station was taken out of service yesterday, leaving Ontario's electricity system with a dwindling supply of power to get it through the summer heat.
Ontario Power Generation said Pickering B reactor unit 5 was taken out of service "for a short maintenance outage." The company plans to inspect and service valve and pump seals on the reactor's primary heat transport system.
Pickering A units 1 and 4, refurbished in 2005 and 2003 respectively, have been down for maintenance since early June and are expected to remain offline for most of the summer as work continues on a backup electrical system.
Terry Young, a spokesperson for the Independent Electricity System Operator, which manages supply and demand on the grid, said the loss of a third reactor could put strain on the system, but so far the weather has been co-operating.
