Click here to read about Pickering and Darlington Reporting to the CNSC.

2011, Q1

[Mar. 26, 2011]: On Mar. 25, Pickering Nuclear experienced a brief partial loss of power on its Unit 1 reactor, while performing start up activities.

Standby systems automatically restored the power, with no impact on employee, public or equipment safety. Pickering's operating staff responded according to procedure and notified the proper authorities of this low level, but reportable event. Start up activities resumed on Unit 1, following a maintenance outage. Pickering Units 4, 6, 7 and 8 are all operating at or near full power, while planned maintenance outage work on Unit 5 continues.

[Mar. 25, 2011]: Mark Elliot, Senior Vice President, Nuclear Engineer and Chief Nuclear Engineer responds to CNSC request pursuant to subsection 12(2) of the General Nuclear Safety and Control Regulations: Lessons Learned from Japanese Earthquake. Read more and visit the Japan Earthquake web page.

[Mar. 15, 2011]: On March 14 Pickering Nuclear had an unintended water release into the environment. The event was a low level regulatory event with only negligible effect to the environment and no public health implications.

A pump seal failure at the Pickering Nuclear A station released an estimated 73,000 litres of filtered water to Lake Ontario on March 14. (This is a conservative estimated calculation for the maximum possible release.) The release was attributed to a faulty pump seal. The release was immediately stopped upon discovery and the pump seal is being replaced.

The filtered (demineralised) water contained trace amounts of tritium, far below any regulatory limits. Routine content of tritium in water at local water treatment plants is generally between six and 10 becquerels per litre some of which is naturally occurring in Lake Ontario and some from the nuclear station and other sources. The estimates of the maximum potential impact of this release means a tritium increase of .56 becquerels per litre, still well within normal range.

The provincial standard for tritium in drinking water is 7,000 becqerels per litre. All appropriate regulatory agencies and stakeholders were notified.

From a regulatory perspective, this is a very low level event. There is no impact to quality of drinking water.

[Mar. 7, 2011]: Unit 4 at Pickering Nuclear was safely shut down on Feb. 24, 2011 to allow replacement of a degraded seal on a moderator system pump. A public notification of this shutdown was issued. Following the unit shutdown, station staff identified that the pump seal had begun releasing some moderator water inside the moderator room and then into a sump designed for water collection in this kind of event. This occurred within the reactor building. They immediately took action to stop the release and to begin recovering the water which contained some tritium.

Testing confirmed tritium emissions remained within normal weekly range and well below any regulatory limit. The event did not trigger any emergency notification levels. The unit is expected to return to service later this month.

Ontario Power Generation adheres very closely to the principles of a strong Nuclear Safety Culture as laid out in best practices by the Institute of Nuclear Power Operations (INPO) organization. Principle #4 of a strong nuclear safety culture is, “Decision making reflects safety first.”

During the shutdown, as a precautionary measure and to ensure a focused response to the pump seal release, the Pickering A Shift Manager activated Pickering Nuclear’s Site Management Centre (SMC), a cross-functional team of specially-trained issue response experts from different areas of the nuclear organization, to provide technical support to the crew. While this team also responds in emergency situations, in this case the team was providing technical assistance, not emergency response. Excellent support was provided by the entire organization and the issue was resolved in a timely manner.
