Independent Environmental Monitoring Program: Bruce A and B Nuclear Generating Stations

Bruce Power is licensed by the CNSC to operate the Bruce A and B nuclear generating stations, located along the eastern shore of Lake Huron in Kincardine, Ontario. The Bruce Power site includes the Bruce A and Bruce B nuclear power plants, which house eight CANDU reactors. All eight of these units are currently operational, with a production capacity of 6,232 megawatts of electricity. Bruce Power also operates the Central Maintenance and Laundry Facility (CMLF) at the Bruce Power site.

Other licensed facilities at the Bruce site include the Western Waste Management Facility (WWMF) and the Douglas Point Waste Management Facility. Ontario Power Generation (OPG) owns and operates the WWMF for the management of low- and intermediate-level radioactive waste and used fuel dry storage. Canadian Nuclear Laboratories Limited (CNL) operates the Douglas Point Waste Management Facility which consists of a permanently shut down, partially decommissioned CANDU reactor. The facility is currently in the long-term "storage with surveillance" phase of the decommissioning program.

Releases result from the operation of the Bruce Power site, the OPG WWMF and the CNL Douglas Point Waste Management Facility. The predominant releases from the Bruce Power site are from the BNGS. Bruce Power runs a comprehensive environmental protection program to monitor and control nuclear and hazardous substances released from the BNGS, determine concentrations of contaminants in the environment and assess exposure to the public.

The Independent Environmental Monitoring Program (IEMP) results for 2013, 2015 and 2016 confirm that the public and the environment around the site are safe and that there are no expected health impacts

Footnote 3

For radiological parameters where no guidelines exist, CNSC reference levels were established based on conservative assumptions using CSA Standard N288.1-14. The reference level for a particular radionuclide in a particular medium (e.g., water, air, food) represents the activity concentration that would result in a dose of 0.1 mSv/a, a dose at which no health impacts are expected.

Background

Under the Nuclear Safety and Control Act (NSCA), licensees of nuclear facilities are required to implement an environmental monitoring program to demonstrate that the public and the environment are protected from emissions related to the facility's nuclear activities. The results of these monitoring programs are submitted to the Canadian Nuclear Safety Commission (CNSC) to ensure compliance with applicable guidelines and limits, as set out in regulations that oversee Canada's nuclear industry.

The CNSC has implemented its IEMP to verify that the public and the environment around licensed nuclear facilities are protected. It is separate from, but complementary to, the CNSC's ongoing compliance verification program. The IEMP involves taking samples from publicly accessible 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. Since the implementation of the IEMP, the area outside of the BNGS site perimeter was sampled in 2013, 2015 and 2016.

2016 results

The 2016 IEMP sampling plan for the BNGS site focused on nuclear contaminants. A site-specific sampling plan was developed based on Bruce Power's approved environmental monitoring program and the CNSC's regulatory experience with the site. In 2016, samples were collected in publicly accessible areas outside the BNGS site perimeter and included air samples, lake water, soil and sediment, vegetation and food such as meat and produce from local farms. View detailed sampling data.

The radioactivity measured in air, water, sediment, soil and vegetation samples, as well as samples of meat and produce were below available guidelines and CNSC reference levels. These results are similar to what was found in 2015 and 2013. CNSC reference levels are based on conservative assumptions about the exposure that would result in a dose of 0.1 mSv/year. No health impacts are expected at this dose level.

2015 results

The 2015 IEMP sampling plan for the BNGS site focused on nuclear contaminants. A site-specific sampling plan was developed based on Bruce Power's approved environmental monitoring program and the CNSC's regulatory experience with the site. In 2015, samples were collected in publicly accessible areas outside the BNGS site perimeter and included air samples, lake water, soil and sediment, vegetation and food such as meat and produce from local farms. View detailed sampling data.

The radioactivity measured in air, water, sediment, soil and vegetation samples, as well as samples of meat and produce, were below available guidelines and CNSC reference levels. CNSC reference levels are based on conservative assumptions about the exposure that would result in a dose of 0.1mSv/year. No health impacts are expected at this dose level.

2013 results

The 2013 IEMP sampling plan for the BNGS focused on radiological (nuclear) contaminants. A site-specific sampling plan was developed based on Bruce Power's approved environmental monitoring program, and the CNSC's regulatory experience with the site. In 2013, samples were collected in publicly accessible areas outside the perimeter of BNGS and included the sampling of air, soil, vegetation, lake water and sediment, and food such as meat, fish and produce from local farms. View detailed sampling data.

The measured radioactivity in air, soil, vegetation, water and sediment samples, as well as samples of fruit, vegetable, meat and fish, were below CNSC reference levels and are within known natural background levels. CNSC reference levels are based on conservative assumptions about the exposure that would result in a dose of 0.1mSv/year. No health impacts are expected at this dose level.

Conclusions

The IEMP results indicate that the public and the environment around the BNGS are protected and that there is no unreasonable risk to health and the environment. The IEMP results are consistent with the results submitted by Bruce Power, demonstrating that the licensee's environmental protection program protects the health and safety of people and the environment.
