The site was later incorporated as AECL. 1945 A first for Canada Zero Energy Experimental Pile (ZEEP) reactor comes online at the Chalk River site. This was the first controlled nuclear chain reaction outside of the United States. ZEEP was a small reactor which helped guide the development of the larger National Research X-perimental (NRX) reactor. PreviousNext Environmental Protection CNL factors sustainable development into all activities, from the boardroom to the lunchroom to the laboratory. See Performance Reports Facilities CNL’s Chalk River Laboratories are the largest single complex in Canada’s science and technology community. The site contains more than 50 unique facilities and laboratories including several licensed nuclear facilities.
