Nuclear Power Demonstration Closure Project
Canadian Nuclear Laboratories (CNL) is proposing to decommission the Nuclear Power Demonstration Waste Facility, a former nuclear generating station that operated until 1987. The facility is located in Renfrew County, Ontario, on the south bank of the Ottawa River approximately 225 kilometres northwest of Ottawa.
The structures that currently remain onsite include the main reactor building, a diesel generator, a ventilation stack, a pressure relief duct, a guardhouse, foundations from previously removed structures, two landfills, buried utilities and drainage systems, and temporary structures such as sea containers and portable washrooms.
CNL is proposing an in situ (leaving in place) decommissioning approach. The following activities are proposed:
- assembly and operation of a grout batch mixing plant
- grouting of below-grade (underground) structures
- removal of above-grade structures for use as backfill
- installation of concrete cap and engineered barrier over the grouted area
- final site restoration
- long-term care and maintenance activities
Some temporary infrastructure – such as mobile offices and washrooms, as well as an increase to the electrical services – would also be required in order to facilitate decommissioning. Water-holding tanks and fuel storage may also be required on site to support the proposed project. Additional groundwater monitoring wells would be installed, as required, to monitor the performance of the in situ decommissioned facility.
Under the Nuclear Safety and Control Act, CNL's proposal requires an amendment to its existing Decommissioning Waste Facility Licence issued by the Canadian Nuclear Safety Commission (CNSC). An environmental assessment (EA) conducted under the Canadian Environmental Assessment Act, 2012 is required, and an EA decision affirming that the proposed activities will not cause significant adverse environmental effects, before the CNSC can make a licensing decision on this proposal.
