The CNSC requires nuclear power plants to conduct a full-scale emergency exercise every three years to test emergency response plans, decision-making functions, response capabilities and interoperability. The goal is to test the licensee, response agencies, and municipal, provincial and federal government responders’ ability to mitigate the impact of a nuclear accident.
If you live within 50 km of the Bruce Power Nuclear Generating Station, you will have received information about what to do in the unlikely event of a nuclear accident from Bruce Power. For more information visit Be Prepared Grey Bruce Huron. When you receive this information, read it carefully and store it in an easily accessible place. You can also attend public information sessions held by local authorities and Bruce Power. For more information on CNSC requirements, consult REGDOC-2.10.1, Nuclear Emergency Preparedness and Response.
As with any emergency, you can prepare your family by:
Periodic safety review
A periodic safety review (PSR) is an international best practice that was adopted by the CNSC in 2015. In addition to the overall safety performance review of licensees, which incorporates reviews of several safety factors, a PSR requires a comprehensive review of plant design and processes. The purpose is to compare current design with modern codes and standards to identify reasonable and practical plant or program modifications to enhance safety and enable safe, long-term operation.
As part of licensing conditions set out by the CNSC, PSRs are conducted every 10 years at all Canadian nuclear power plants.
CNSC regulatory document REGDOC-2.3.3, Periodic Safety Reviews, requires the PSR to be conducted in four phases. Each phase is thoroughly reviewed by CNSC staff prior to accepting the document and proceeding to the next phase:
- PSR basis document, an agreement between Bruce Power and the CNSC on how the PSR will be achieved. (Bruce A and Bruce B)
- Conduct of the safety factors reviews and identification of findings (Bruce A and Bruce B)
- Analysis of the findings and their integral impact on the NPP's safety (global assessment report or GAR)
- Preparation of a safety improvements plan (integrated implementation plan)
All PSR documents are available through Bruce Power'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 Bruce Power assessed the potential risks for the current whole-site operation, both Bruce A and Bruce B generating stations and additional facilities, to determine the potential risks to the environment and human health from current operations. Bruce Power's ERA also included a predictive environment risk assessment for continued operations including major component replacement.
Bruce Power's ERA is available on Bruce Power's website.

Bruce A refurbishment and continued operations follow-up monitoring program
Although the formal environmental assessment (EA) process related to the life extension project of Bruce Power's units 1–4 concluded in July 2006, a follow-up monitoring program was established to verify the predictions that were made in the EA. Bruce Power provided annual updates to the CNSC on the status of the project until the conclusion of the follow-up monitoring program in 2015. CNSC staff reviewed the reports and concluded that most of the predictions made in the EA that were part of the EA follow-up monitoring program have been verified in that there have been no significant adverse environmental effects as a result of the refurbishment projects. The results were inconclusive for two elements: substrate temperatures of the thermal plume and impacts to fish and the population level impacts on Deepwater Sculpin from cooling water intake. Additional work on these elements will be addressed within the ERA and follow-up monitoring program.
Bruce Power's annual updates are available on Bruce Power's website.

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 its reviews take into consideration the requirements of the revised Fisheries Act, as per a memorandum of understanding with Fisheries and Oceans Canada. Based on Bruce Power's 2013 and 2014 fish impingement and entrainment monitoring results, CNSC staff submitted its review of the effects due to impingement and entrainment at the Bruce Power facility to Fisheries and Oceans Canada, which determined Bruce Power requires an authorization under section 35 of the Fisheries Act for the death of fish due to impingement and entrainment at the cooling water intake.

Latest licensee public disclosures
As part of CNSC's regulatory requirements, major licensees must have robust public information and disclosure programs in place. These programs, for nuclear power plants, include a disclosure protocol developed in consultation with community stakeholders. You may visit Bruce Power's Web site for all updates triggered by the protocol's disclosure criteria.

Adjacent nuclear facilities and projects
Ontario Power Generation Deep Geologic Repository
The site preparation, construction and operation of a Deep Geologic Repository (DGR) is proposed for the disposal of low- and intermediate-level radioactive wastes on the Bruce Site in Tiverton. The DGR will also hold waste produced from the continued operation of the Bruce, Pickering and Darlington nuclear generating stations.
Find out more about the status of this project.
Western Waste Management Facility
The Western Waste Management Facility is owned and operated by Ontario Power Generation (OPG) and stores low level radioactive wastes from the Bruce A and B reactors as well as from the Pickering and Darlington nuclear generating stations. The Western Waste Management Facility also houses used fuel from Bruce A and B along with refurbishment waste from Bruce A.
Douglas Point Waste Management Facility
The Douglas Point Waste Management Facility (DPWMF) is located at the site of the former Douglas Point Nuclear Generating Station (DPNGS) situated on the Bruce nuclear site. Decommissioning of this prototype reactor began in 1986, and the transfer of spent fuel from wet storage in the reactor pool to a dedicated dry storage facility was completed by 1987. The DPWMF is presently in the storage-with-surveillance phase of a deferred decommissioning program and is closed to the receipt of new wastes.
Bruce Heavy Water Plant
The Bruce Heavy Water Plant (BHWP) was a Class 1B nuclear facility contained within the boundaries of the Bruce nuclear site located in Tiverton, Ontario. It began producing heavy water in 1973 and continued until the last production facilities were shut down in 1998. The demolition of the BHWP was completed in 2006. All contaminated soil has been remediated, and the project is in the end-state of environmental monitoring.
