Natural Resources committee  I'll provide a short response. Essentially the Nunavut Impact Review Board is responsible for conducting the environmental assessment. What the CNSC provides is the scientific and technical support for all aspects of the environmental assessment, and we play the role of coordina

Natural Resources committee  Essentially, we looked at the characteristics of the steam generators in terms of the content of radioactivity and the characteristics of the generator in terms of the radionuclides, which are not soluble, so it's a coating inside the tubes that is not soluble in water. There are

Natural Resources committee  We conducted two types of assessments to ensure workers are protected. The first scenario we developed focused on the drivers of the trucks making a round trip with the 16 generators. We concluded that the worker would be exposed to 0.02 mSv.

Natural Resources committee  Thank you. The 2006 environmental assessment was conducted for the retrofit of units at the Bruce Power plant. Waste management was only a small part of the assessment.

It is a safe standard. The dose associated with this level of tritium in drinking water.... If someone were t

Natural Resources committee  Mr. Chair, member of Parliament, the State of California has a legally enforceable drinking water standard for tritium of 740 becquerels per litre. That's the same as other U.S. states. The 15 becquerels per litre is not an enforceable standard; it's what is being referred to—

Natural Resources committee  It's 740.

Natural Resources committee  That's correct.

Natural Resources committee  Okay.

Natural Resources committee  To put things in perspective, of all the nuclear facilities operating in Canada, nuclear power plants, the Chalk River site, the level of tritium in drinking water supplies has always been below 20, and in most cases it is below 15. So although the guideline or the standard is 7,

Natural Resources committee  Mr. Chair, my understanding is that there were two other commission proceedings related to the AECL Chalk River site. One was on an environmental assessment being conducted by the CNSC for the Chalk River site and the other one was on a licence amendment.
