"DO you have any reports or white papers to back that up? and water and water vapor are the only things coming out of a cooling tower and a redactor"

"# In 1983, a pressure tube in Pickering Reactor #2 ruptured, dumping coolant into the reactor building. This accident resulted in the retubing of all four reactors at the Pickering "A" Nuclear Station, at a cost of about $1 billion (Cdn) -- more than the original cost of the station.
# In August 1992, a tube-break in Pickering Reactor #1 dumped 2,000 litres of heavy water contaminated with 2,300 trillion becquerels of radioactive tritium into Lake Ontario. It was the largest tritium release in CANDU history, shutting down a nearby drinking water plant, and raising tritium levels in Toronto drinking water. Tritium causes cancer and birth defects.
# In December 1994, Pickering reactor #2 had a major Loss of Coolant Accident (LOCA) spilling 185 tonnes of heavy water. The Emergency Core Cooling System (ECCS) was used for the first time ever at a CANDU reactor to prevent a meltdown.
# In May 1995, a valve failure caused a 25 tonne leak of radioactive heavy water at Bruce Reactor #5. This accident involved the same equipment which caused the December 1994 LOCA at Pickering reactor #2.
# In February 1996, 500 tonnes of water spilled from the Pickering #6 reactor. Primary and backup heat sinks were lost in the reactor core. A 30 kg. valve component blew two metres into the air, narrowly missing a worker, and service water shot up to the reactor building dome.
# In April 1996, Pickering reactor #4 had a heavy water leak that released 50 trillion becquerels of tritium into Lake Ontario. The level of tritium in local drinking water reached 100 times background level. "

"At the Bruce nuclear complex, tritium is released to the station cooling water effluent stream (Condenser Cooling Water) which discharges into Lake Huron."
