Independent Environmental Monitoring Program: BWXT Nuclear Energy Canada Inc. - Peterborough
BWXT Nuclear Energy Canada Inc. (BWXT), formerly GE Hitachi Nuclear Energy Canada, is licensed by the Canadian Nuclear Safety Commission (CNSC) to operate a nuclear fuel fabrication facility, located in Peterborough, Ontario. BWXT manufactures nuclear fuel bundles for Canada’s nuclear power plants from uranium dioxide (UO2) powder. The BWXT Peterborough facility assembles UO2 pellets into CANDU reactor fuel bundles. BWXT has a comprehensive environmental protection program to monitor and control nuclear and hazardous substances released from the site, determine concentrations in the environment, and to assess exposure to the public.
Independent Environmental Monitoring Program (IEMP) results from 2014, 2018 and 2019, along with conclusions of available health studies for uranium processing facilities, confirm that the public and the environment in the vicinity of the BWXT Peterborough facility are protected and that there are no expected health impacts.

Under the Nuclear Safety and Control Act (NSCA), licensees of nuclear facilities are required to implement environmental monitoring programs to demonstrate that the public and the environment are protected from emissions related to the facilities’ nuclear activities. The results of these monitoring programs are submitted to the CNSC to ensure compliance within 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 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 laboratory for testing and analysis. The area outside of the BWXT Peterborough site perimeter was sampled in 2014, 2018 and 2019.
2014, 2018 and 2019 results
The IEMP sampling plans for BWXT Peterborough facility focused on both radioactive and hazardous substances, such as uranium and beryllium. Uranium is both a radioactive substance (it decays at a slow rate by emitting gamma radiation) and a hazardous substance (since exposure to uranium leads to chemical toxicity). Beryllium is a hazardous substance used in the fuel bundle manufacturing process. A site-specific sampling plan was developed based on the licensee’s approved environmental monitoring program and the CNSC’s regulatory experience with the site. In July 2014, July 2018, and May 2019, CNSC staff collected air, soil, and water samples in areas outside the BWXT Peterborough site perimeter. The levels of uranium and beryllium measured in the samples were below available guidelines.
Further to the BWXT licence renewal hearing in March 2020, the CNSC conducted soil resampling for beryllium, as directed by the Commission, at sites adjacent to BWXT’s Peterborough facility. The soil samples were analyzed at the CNSC lab, and the results did not indicate any significant changes in concentrations of beryllium in the soil in Peterborough. The CNSC provided a supplemental submission on the resampling results for the Commission’s consideration in BWXT’s licence renewal request.
The IEMP 2014, 2018, and 2019 results indicate that the public and the environment in the vicinity of the BWXT Peterborough facility are protected and that there are no expected health impacts. These results are consistent with the results submitted by BWXT and the conclusions of available health studies for uranium processing facilities – demonstrating that the licensee’s environmental protection program protects the health and safety of people and the environment.
Focus on health
The CNSC also conducts studies to assess the health of the public near nuclear facilities. Several studies have been carried out in Port Hope, Ontario, where uranium has been processed to manufacture nuclear fuel for decades. These studies have consistently demonstrated that people who live near uranium processing facilities, such as BWXT, are as healthy as the rest of the Canadian general population.
