Nuclear Power Demonstration

The Nuclear Power Demonstration (NPD) reactor operated from 1962 until 1987. It was Canada’s first nuclear power reactor to supply electricity to Ontario Hydro’s grid, and it served as a training facility for reactor engineers and operators. In 1988, following permanent shutdown of the reactor, and removal of the fuel and power generating equipment from the site, Ontario Hydro transferred the responsibility for monitoring and licensing NPD to Atomic Energy of Canada Limited (AECL). The partially decommissioned site is now overseen by Canadian Nuclear Laboratories and is licensed as a waste facility.

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 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
  • preparation for 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 onsite 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). Before the CNSC can make a licensing decision on this proposal, an environmental assessment (EA) conducted under the Canadian Environmental Assessment Act, 2012 is required, as is an EA decision affirming that the proposed activities will not cause significant adverse environmental effects.

On March 8, 2017, the Commission issued a decision on the extent of the information to be included in the EA. The decision took into account the public comments received related to the project description, as well as CNSC staff recommendations. The Commission determined that the proposed project must include the factors mandated in paragraphs 19(1)(a) to (h) of CEAA 2012, with no additional factors requiring consideration.
