Thousands of liters of radioactive water have been released into Lake Ontario as a result of an accident at a Canadian nuclear power plant, according to authorities.

"The event was a low level regulatory event with only negligible effect to the environment and no public health implications," Ontario Power said in a statement on Wednesday.

The power company, which is owned by the Ontario provincial government, said 73,000 liters (19,280 gallons) of was released into Lake Ontario from the Pickering Nuclear Station.

The Pickering , one of five in Canada, is located 35 kilometers (22 miles) east of Toronto, the country's largest city with 2.6 million inhabitants.

The company blamed the leak on a faulty pump seal and said it was stopped as soon as it was discovered.

"From a regulatory perspective, this is a very low-level event. There is no impact to quality of ," the power company said.

The Canadian commission on nuclear safety also said the risk to the environment and human health was "negligible."

The incident occurred against the backdrop of a nuclear crisis in Japan that has prompted debate in many countries about the safety of nuclear power plants.

They probably dumped this stuff right now because no one would be upset over it - everybody is looking at Japan. in other times people would have been upset.

This wouldn't even be news if the Japanese nuclear situation were not happening... Score one for sensationalized journalism.

How radioactive was the water? It's sort of crucial to the whole story. If it's a "low level regulatory event," it's more than likely that the water was not seriously radioactive.

'the waste produced by coal plants is actually more radioactive than that generated by their nuclear counterparts. In fact, the fly ash emitted by a power planta by-product from burning coal for electricitycarries into the surrounding environment 100 times more radiation than a nuclear power plant producing the same amount of energy."
For reference.

For anyone interested here is the release by OPG (Ontario Power Generation) about the leak:

4.6 / 5 (10) Mar 17, 2011
Some interesting figures from the OPG release above:
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

The estimates of the maximum potential impact of this release means a tritium increase of .56 becquerels per litre

So the conservatively estimated leak (assuming highest possible volume actually did leak) will result in an increase of the tritium levels in the water from 6-10 to 6.6-10.6.

Some legal limits of tritium in drinking water (from wikipedia):
Canada: 7000 Bq/L
United States: 740 Bq/L
World Health Organization: 10,000 Bq/L
European Union: 100 Bq/L (investigative threshold)

Score one for sensational journalism.

Thank you, Temple. Quality post.

Perhaps the nuclear pushers can move into the plants in order to act as shields to help the rest of us trust their judgment, until a disaster strikes which can't be covered up.

This just in: it was announced today that a major news organization, AFP, had on March 17 released 73,000 liters (19,280 gallons) of drivel onto the internet.

nothing here - the area of the plant is NOT inhabited by many important people - move along.........
