Pickering Nuclear Generating Station
Notice of public hearing and participant funding
The CNSC will hold a two-part public hearing to consider an application from Ontario Power Generation (OPG) to renew its nuclear power operating licence for the Pickering Nuclear Generating Station for a period of 10 years. OPG intends to cease commercial operation of all Pickering units on December 31, 2024.
Members of the public, Indigenous groups and other stakeholders who have an interest or expertise in this matter or information that may be useful to the Commission in coming to a decision are invited to comment on OPG's application. Through its Participant Funding Program, the CNSC is offering a total of $100,000 in funding to assist in reviewing OPG's application and associated documents and providing topic-specific interventions to the Commission.
- December 1, 2017: Deadline for submitting a participant funding application
- March 5, 2018:OPG’s submission and CNSC staff’s recommendations are available upon request to the Secretariat
- April 4, 2018: Part 1 of the public hearing in Ottawa
- May 7, 2018: Deadline for filing a request to intervene
- June 25–29, 2018: Part 2 of the public hearing at the Pickering Recreational Center, 1867 Valley Farm Road Pickering, ON
Ontario Power Generation (OPG) owns and is licensed to operate the Pickering Nuclear Generating Station (NGS), located in the municipality of Pickering on the north shore of Lake Ontario. The Canadian Nuclear Safety Commission (CNSC) has full-time staff onsite who perform inspections to evaluate if operations are safe and to verify compliance with licence conditions. Furthermore, the CNSC employs technical and regulatory specialists at its head office in Ottawa, who perform assessments and evaluations of OPG's compliance with applicable requirements.
In 2017, OPG submitted an application for a 10-year renewal of the Pickering NGS power reactor operating licence, which expires on August 31, 2018. As OPG intends to cease commercial operation of the Pickering NGS on December 31, 2024, the proposed licence period would cover three phases of operational activities: continued commercial operation until December 31, 2024; a stabilization phase (post-shutdown defuelling and dewatering) lasting approximately two to three years; and the beginning of safe storage for six reactor units. The safe storage phase marks the beginning of station decommissioning.

Periodic safety review
A periodic safety review (PSR) is an international best practice that was adopted by the CNSC in 2015 and described in REGDOC-2.3.3 Periodic Safety Reviews. One major activity of a PSR is to evaluate overall plant safety by integrating reviews of 15 safety factors covering elements related to the plant's design, condition, performance and operation, as well as to organizational and human performance. The PSR assesses the extent to which the Pickering NGS conforms to modern codes and standards, and identifies practicable physical or programmatic modifications to enhance safety until the end of commercial operation planned at the end of 2024.
As part of licensing conditions set out by the CNSC, a PSR is conducted every 10 years at all Canadian nuclear power plants.
As per CNSC REGDOC-2.3.3, the PSR is to be conducted in four phases. Each phase is thoroughly reviewed by CNSC staff before proceeding to the next phase:
- PSR basis document – an agreement between OPG and the CNSC on the scope, depth of the PSR
- Conduct of the safety factor reviews and documentation of the identified findings in 15 safety factor reports
- Analysis of the findings and their integral impact on the plant safety (global assessment report [GAR])
- Preparation of a safety enhancement plan (integrated implementation plan [IIP])
All PSR documents are available through OPG's website.

Environmental risk assessment
An environmental risk assessment (ERA) is a systematic process used to identify, quantify and characterize the risk posed by contaminants and physical stressors in the environment to biological receptors, including humans.
The ERA for OPG's Pickering NGS assessed the potential risks to human health and the environment associated with the facility operations in the years leading up to the end of commercial operations.

The CNSC's Independent Environmental Monitoring Program
The CNSC has implemented its Independent Environmental Monitoring Program (IEMP) to verify that the public and the environment around licensed nuclear facilities are protected. The IEMP involves taking samples from public areas around the facilities, and measuring and analyzing the amount of radiological (nuclear) and hazardous substances in those samples. CNSC staff collect the samples and send them to the CNSC's state-of-the-art laboratory for testing and analysis. For more information, visit the IEMP Web page.
Since the implementation of the IEMP, the area outside of the Pickering NGS perimeter was sampled in 2014, 2015 and most recently 2017. Results from the sampling campaigns confirm that the public and the environment around the Pickering NGS are safe and that there are no health impacts.
Fisheries Act authorization
CNSC staff continuously review impacts to the environment, including impacts to fish and fish habitat, under the Nuclear Safety and Control Act. The CNSC ensures that its reviews consider the requirements of the revised Fisheries Act, as per a memorandum of understanding with Fisheries and Oceans Canada.
|May 2015||Fisheries and Oceans Canada conducts an investigation and issues a letter to OPG requiring OPG to submit an application for an authorization under paragraph 35(2)(b) of the Fisheries Act. As part of the Pickering NGS Fisheries Act application, OPG proposes an offset project, which once submitted, is deemed to require its own authorization. For this reason OPG has been working with Fisheries and Oceans Canada directly on the submission of a complete Fisheries Act application.|
|July 2017||OPG submits an application to Fisheries and Oceans Canada for authorization under paragraph 35(2) of the Fisheries Act.|
|August 30, 2017||Fisheries and Oceans Canada conducts its review of the application and deems the application incomplete. Outstanding information items include additional details on measures and standards to avoid or mitigate serious harm to fish, residual serious harm to fish after implementation of avoidance and mitigation measures and standards, and additional information on the proposed offsetting plan|
|October 2017||A fisheries offset productivity monitoring workshop is held with OPG, Fisheries and Oceans Canada and CNSC staff, to define appropriate methods to measure and evaluate fisheries productivity at OPG's proposed offset project at the Big Island Wetland.|
|December 2017||OPG submits a revised application for authorization under paragraph 35(2) of the Fisheries Act.|
|January 2, 2018||Fisheries and Oceans Canada notifies OPG that its application is considered complete.|
|January 17, 2018||Fisheries and Oceans Canada issue a Fisheries Act authorization to OPG for the Pickering NGS.|
Participant Funding Program
The CNSC made a total of $100,000 available through its Participant Funding Program (PFP) to assist members of the public, Indigenous groups, and other stakeholders in providing value-added information to the Commission through informed and topic-specific interventions. This funding will be used by stakeholders to review OPG's licence renewal application and other relevant documentation specifically related to the application, and to prepare for and participate in the Commission public hearing.
The public, Indigenous groups and other stakeholders were informed of the availability of participant funding through a series of public communications:
- Posting of the PFP funding announcement on the PFP section of the CNSC website
- News release and email to subscribers
- Online and print advertisements
- Notification by letter to potentially interested Indigenous groups
The deadline for applications was December 1, 2017. A Funding Review Committee (FRC), independent from CNSC staff review the funding applications received, and make recommendations on the allocation of funding to eligible applicants. Based on recommendations from the FRC, the CNSC awards participant funding to recipients, who are required to submit a written intervention and make an oral intervention at the Commission public hearing.
