Provincial Nuclear Emergency Response Plan Forward and Synopsis

The Government of Ontario is responsible for leading and directing the preparations for, the response to, and recovery from nuclear and radiological emergencies that affect Ontario. The Provincial Nuclear Emergency Response Plan (PNERP) details how the province will respond to nuclear and radiological emergencies.

Ontario’s nuclear facilities have operated since 1962, for over 63 years, without having any incidents that have posed a risk to public safety. Nuclear Facilities have produced over 3600 TWh of electricity with a combined total of over 4.7M reactor operating hours without incident. Ontario’s nuclear generating facilities are world leaders when it comes to being the safest and cleanest form of electrical production.

The revised PNERP is based upon a new technological study that has enabled it to be flexible, agile, and applicable to all existing, planned e.g. Small Modular Reactors (SMRs), and new future nuclear reactor technologies. The revised PNERP supports the Government of Ontario’s policy of growing its nuclear power production footprint anywhere in Ontario while ensuring public safety.

Ontario has adopted a SAFE, SAFER and SAFEST approach to nuclear emergency management. The PNERP’s planning basis, has accounted for the safety record of Ontario’s nuclear industry and the substantive improvements that have been implemented including the enhanced safety systems that have been introduced in a post Fukushima environment.

The PNERP and its existing Nuclear Emergency Management Program (NEMP) is built upon the industry’s safe foundation to make Ontario SAFER.

The revised PNERP is an essential component to Ontario’s setting of the industry standard and its ability to ensure Ontario is Safe, Practiced and Prepared in a nuclear and radiological context for now and into the future.

The PNERP:

  • Pursuant to section 8 of the Emergency Management and Civil Protection Act (EMCPA) the Lieutenant Governor in Council shall formulate an emergency plan respecting emergencies arising in connection with nuclear facilities, and any provisions of an emergency plan of a municipality respecting such an emergency shall conform to the plan formulated by the Lieutenant Governor in Council and are subject to the approval of the Minister responsible for emergency management, and the Minister responsible for emergency management may make such alterations as he or she considers necessary for the purpose of co-ordinating the plan with the plan formulated by the Lieutenant Governor in Council.
  • The PNERP describes the general roles and responsibilities for the off-site response to a radiological or nuclear emergency in Ontario and includes seven Implementing Plans. (Note: the province is responsible for directing the response to all nuclear or radiological emergencies in/affecting Ontario.)
  • The PNERP is operationally applied through its detailed Implementing Plans that are designed specifically for each major nuclear facility in or within the immediate vicinity of Ontario and or for all other types of radiological emergencies. 

The Scientific basis for the revised PNERP:

  • A new technological study and planning basis that is applicable to existing CANDU reactors, new large nuclear reactors, and Small Modular Reactors was developed.
  • It was developed in collaboration with nuclear health physicists, nuclear engineers, and reactor safety experts from Ontario Power Generation (OPG), Bruce Power (BP), Chalk River Nuclear Laboratories (CNL), Emergency Management Ontario (EMO) and the Chief Nuclear Engineer from Calian Nuclear Ltd. (Note: the new technical study and planning basis have been peer reviewed and endorsed by this scientific cohort.)
  • The existing 2017 PNERP’s technical study and planning basis, was revised to account for post-Fukushima enhancements to safety systems and designs of operating nuclear facilities in the province as well as incorporated into lessons learned from continuous improvements, international best practices and standards. Note: the flexibility/agility provided by the new technological study and planning basis for the revised PNERP supports an expansion of Ontario’s nuclear footprint across the province.

The Duty to Consult regarding the PNERP

The province has a Duty to Consult regarding the PNERP. Emergency Management Ontario (EMO) has engaged and consulted with all First Nation and Indigenous communities in Ontario that are close to or have traditional territories that could be affected by licensed CNSC facilities within Ontario. (Note: the implementation of the PNERP during the unlikely event of a nuclear or radiological emergency could affect First Nation or Indigenous community rights etc., thus we continue to work together on a partnership basis regarding nuclear emergency management.)

“Over the next 25 years, demand for electricity in Ontario is projected to grow by at least 75 per cent, the equivalent of adding four and a half cities the size of Toronto.

Ontario’s energy policy will determine the success of our province’s economy, today and for a generation to come.

It’s why for the last seven years your government has been hard at work restoring the promise of Ontario’s energy advantage. Now, today, the province boasts one of the cleanest grids in North America, with a steady and reliable supply of affordable electricity powering Ontario’s growing economy.

Next, your government will invest unprecedented amounts in new energy production, transmission, and storage to transform our province into a global clean energy superpower, able to export clean energy and technology across the continent and beyond.

This includes the first small modular nuclear reactors in the G7 at Darlington nuclear site, alongside upgrades to existing nuclear facilities at the Darlington, Pickering, and Bruce nuclear generating stations to extend their lifespans and expand their generating capacity.

Your government is also working with interested municipalities and First Nations to dramatically expand Ontario’s energy generating capacity, including exploring building the first new large-scale nuclear power plants in the province in more than 30 years in Bruce County and Port Hope”

Executive Summary

How Ontario responds in the very unlikely event of a nuclear or radiological emergency in this province is the substance of this document. Ontario’s Strategic Response Plan Framework for Nuclear and Radiological Emergency Management is short titled: Provincial Nuclear Emergency Response Plan (PNERP). With increased electricity needs and new, reduced carbon footprint technology, there is a need to meet this moment through development of this framework and nuclear implementing plans that meet or exceed all national and international public safety standards.

This plan is the guiding document for the province to prepare its ministries and employees to respond to a radiological or nuclear emergency within Ontario’s borders, and to consequences that arise due to a nuclear or radiological emergency outside of its borders. In either event, the province’s response shall protect people, the environment and infrastructure by ensuring any necessary radiation exposure is mitigated to the extent possible, which includes taking all reasonable measures to minimize the possibility of radiation exposure health effects.

The plan includes a requirement to provide appropriate information to members of the public and maintain public education on nuclear and radiological hazards. This awareness includes sources of radiation present during daily activities as well as those hazards present in the event of an emergency. During an emergency, the province will provide timely and accurate information to the public regarding protective actions necessary to prevent exposure to harmful levels of radiation and ensure that any exposure is kept as low as reasonably achievable (ALARA).

Furthermore, the province cultivates the expertise of its employees by providing necessary equipment and maintaining high standards of training. The use of appropriate equipment and a high degree of training will help to ensure strong situational awareness in an emergency thereby enabling timely decision making by emergency managers at all levels of government.

This is a scientifically based document for which a new, evidence-based technical study was conducted that has and will form the planning basis of the site-specific implementing plans for utilities and the nuclear-designated municipalities in Ontario regarding existing CANDU reactors and all new future builds/technologies including, but not limited to Small Modular Reactors (SMRS) that are being and or will be introduced anywhere within Ontario. A standardized methodology has been developed based upon the work described that is technologically neutral and agile in its application.

The results from the application of the methodology will inform the planning basis and policy decisions that are made by Emergency Management Ontario (EMO) when setting zone sizes and preparedness requirements for emergency planning zones for specific technologies/sites. The details for each technology’s site-specific emergency planning zones are outlined in the individual respective Site-Specific Implementing Plans.

The operational governance structure is based upon the Incident Management System (IMS). A Scientific Section for nuclear and radiological emergency response purposes, has been added to the IMS structure to provide expert scientific information and advice to the EMO Command Structure. Operational details are found in the Site-Specific Implementing Plans. EMO, on behalf of the province, will direct the response to all nuclear & radiological emergencies. EMO’s operational command relationship with provincial ministries, has been detailed in the PNERP. Specific details regarding all aspects of social and media related communications are detailed in separate communications plans.

Based upon the application of the PNERP’s methodology, eight designated/host municipalities have been identified. The roles and responsibilities of the eight designated/host communities are clearly specified in the PNERP and the applicable Site -Specific Implementing Plans so that they can follow EMO’s direction in preparation for, response to and recovery from a nuclear emergency that affects their municipality. The operational relationship between EMO and the licensed nuclear facilities is specified to ensure timely notification, communications and liaison is maintained, and support provided for the PNERP’s operational implementation. The Canadian federal government and identified federal departments have operational support roles as detailed in the PNERP.

First Nation and Indigenous communities have jurisdiction over their respective community’s emergency management programs including nuclear response within their communities. The strategic government to government operational relationship between Ontario as represented by EMO with the First Nation and Indigenous communities that are, or have traditional territories, in proximity to a licensed nuclear facility, has been outlined to ensure notification, mutual operational support and communications: Individual First Nation and Indigenous community’s operational details are specified in their community’s emergency plans and the applicable site-specific implementing plans.

A communications and liaison structure has been detailed for cross boarder operational coordination purposes with contiguous provinces and or states within the United States.

Finally, to ensure its ongoing operational capacity, the PNERP will be reviewed regularly and updated accordingly to ensure that it maintains its applicability in an evolving nuclear radiological environment for a safe, practiced, and prepared Ontario in a nuclear and radiological context.
