http://thechronicleherald.ca/Canada/1055799.htmlOTTAWA — Canada’s nuclear safety watchdog warned last month that it was concerned about an "erosion of safety margins" at the Pickering B nuclear station near Toronto.
A letter from the Canadian Nuclear Safety Commission surfaced Tuesday on the eve of a hearing in which Ontario Power Generation will make the case for renewing the station’s operating licence until 2014.
The commission’s assessment of the station was sent to Patrick McNeil, a senior executive at the provincially owned Crown corporation, on April 7.
"CNSC staff remain concerned with the trend in erosion of safety margins . . . and expect that OPG will address the identified outstanding issues, and, in particular, will develop and implement engineered solutions to re-establish robust safety margins," says the letter.
