Hon. Anne McLellan (Minister of Natural Resources, Lib.)
Mr. Speaker, in response to (a), tritium emissions from the waste site at Atomic Energy of Canada Limited's Chalk River plant do migrate to some degree within a radius of50 kilometres of the plant. However, tritium emission limits are set so that hypothetical doses to the public are always well below the regulatory limits set by the Atomic Energy Control Board. In practice, nuclear facilities do not operate anywhere near their emission limits and Atomic Energy of Canada Limited's Chalk River plant is no exception. The tritium releases from the plant are well below the regulatory limits.
In response to (b), local drinking water is monitored for tritium and the levels observed, being very much less than regulatory limits for the public, are considered safe. Daily samplings are collected at the Pembroke main water supply intake and these are measured monthly to confirm that releases are a small fraction of the regulatory limits.
In response to (c), yes, the radioactive waste disposal site is safely insulated. It is located well inside the plant boundary and is not accessible to the public. The releases of tritium from this site are well below the regulatory limit.
In response to (d), the radioactive waste site is safe and poses no undue risk to humans.
