  Chalk River Laboratories - Wikipedia, the free encyclopedia
By 1944 the Chalk River Labs were opened and in September, 1945 the facility saw the first nuclear reactor outside of the United States go operational.
Chalk River Labs are also near the site of Canada's first nuclear power plant, a partnership between AECL and Hydro-Electric Power Commission of Ontario, which went online in 1962.
Chalk River Labs remain an AECL facility to this day and are used as both a research (in partnership with the NRC) and production facility (on behalf of AECL) in support of other Canadian electrical utilities.

Paulson broke his 20-year-old promise and, in another application for a veteran's pension, cited the Chalk River clean-up as a probable cause of the cancers that had so disrupted his life.
Paulson's cancers were due to his radiation exposure at Chalk River, because his exposure was well within the regulatory guidelines.
Later, when he was summoned to Chalk River to help in the NRU cleanup, he didn't object.

 Guardian Unlimited | Special reports | How one toxic river became the water of life
Half a century ago the River Wandle, which runs for nine miles smack through the middle of some of the least prepossessing housing and industrial estates south London has ever tried to hide, was officially declared an open sewer.
A major sewerage revamp in the mid-Nineties changed the effluent quality, making the river the purest it had run for years; and by then Dutton was being helped by volunteers led by local illustrator Alan Suttie, all energetic passion to Dutton's quiet expertise.
The worst part of the river was down by Earlsfield, at a camp of travelling people, although on Friday's evidence we should actually be calling them 'people who don't travel at all except to throw dead washing-machines and propane canisters into the newly clean Wandle'.

O'Grady is certainly entitled to question the operations of the Chalk River lab upriver from her, but the disposal activities at Chalk River are minor in comparison with Hanford, and the debate should not be needlessly diverted for rhetorical purposes.
However, he then takes the philosophical stand that, even though the effect on both the environment and our health is insignificant, we should oppose the operations at Chalk River, simply because we don't like them.
Rubin accepts the one-per-cent risk of contracting cancer from background radiation in the world around us, but rejects any "greater" risk due to Chalk River's operations -- neglecting to state that this "greater" risk is both insignificant and unmeasurable, as is the one-per-cent risk from background radiation in the first place.

 Letter to the Editor - 1997 May 29
The story, by science writer Tom Spears, discusses an historic radioactive leak from a fuel-storage bay at Chalk River Laboratories' (now decommissioned) NRX reactor, monitored continuously by AECL and reported regularly in public documents to the government regulator, the Canadian Nuclear Safety Commission (CNSC).
In your article "Chalk River's Dirty Secret" (front page, May 28), several citizens of the Pembroke area express doubt as to whether the Ottawa River could dilute the historic radioactive leak from Chalk River's NRX fuel storage bay.
In contrast, the natural radioactivity of the Ottawa River is something like 5 Becquerels per litre, 50 times the activity of the diluted Chalk River water.
