As noted in the recent Hill Times op-ed by Eva Schacherl, Political Opposition Growing to New Reactors, both small modular nuclear reactors AND the high-level fuel waste they produce are EXEMPT from environmental assessment in Canada
From the op-ed:
“The Impact Assessment Act was intended to create “greater public trust in impact assessment and decision-making.” But there will be no federal assessment of nuclear reactors up to 200 thermal MW in size, nor of new reactors built at existing nuclear plants (up to 900 MWth). Yet new tidal power projects, as well as offshore wind farms with 10 or more turbines, need an assessment under the regulations, as do many new fossil fuel projects.”
“Also exempted from federal assessment is the “on-site storage of irradiated nuclear fuel or nuclear waste” associated with small modular reactors. This will make it easier for SMRs’ radioactive waste to be potentially left in the northern, remote, and First Nations communities, where they are proposed to be built.”
This SMR fuel waste exemption was a last-minute insertion in the Impact Assessment Act regulations. It is found in section 28 of the Physical Activities Regulations (the so-called ‘project list’ for the new Impact Assessment Act and reads as follows:
28 The construction and operation of either of the following:(a) a new facility for the storage of irradiated nuclear fuel or nuclear waste, outside the licensed boundaries of an existing nuclear facility, as defined in section 2 of the Nuclear Safety and Control Act, other than a facility for the on-site storage of irradiated nuclear fuel or nuclear waste associated with one or more new fission or fusion reactors that have a combined thermal capacity of less than 200 MWth;
As far the fuel waste from the proposed SMR (the “MMR Project“) at Chalk River is concerned, there is another exemption in section 28 – the phrase “outside the licensed boundaries of an existing nuclear facility” allows it to be kept on site at Chalk River, a licensed nuclear facility.
