A Smart Investment
The Darlington Nuclear Generating Station is one of the top performing nuclear stations in the world. The mid-life refurbishment of this 20-year old facility will ensure continued clean, safe and reliable power for Ontario homes, schools, hospitals and businesses for 30 more years.
Here’s a summary of Darlington Refurbishment’s impact on Ontario’s economy:
- Investing in the Darlington Refurbishment will increase Ontario’s nominal GDP by a total of $14.9 billion and a total of $89.9 billion when calculating in 30 more years of station operations.
- Due to the project’s low import content and heavy reliance on Ontario-based contractors, on average, for every $1 spent on the project, Ontario’s GDP will increase by $1.40.
- Over the project, the refurbishment investment is projected to preserve approximately 3,000 jobs and lift employment by an average of 8,800 jobs per year, or 11,800 per year during the peak period 2014-2026.
- The increase in economic activity and the resulting increase in labour income and corporate profits will boost federal, provincial, and municipal governments’ tax revenues by a total of $5.4 billion. The federal government will collect $13.8 billion in revenue, while the local municipalities in Ontario will collect $356 million.
- Since increased employment and GDP translate into increased income, the project is expected to boost personal income by a total of $61.4 billion between 2017 and 2055 and household income by $53.4 billion within the same timeframe.
- Similarly, the project is expected to raise pre-tax corporate profits by $2.8 billion and the pre-tax income of unincorporated businesses by an additional $253 million. These figures increase to $7.0 billion in corporate profiles and $3.3 billion in business investment when calculating in 30 more years of station operations.
Regulatory Approvals and Reports
Nuclear power plants in Canada are subject to ongoing regulatory oversight by the Canadian Nuclear Safety Commission (CNSC), including regular licence renewal. OPG received approval to operate Darlington’s power reactor’s to 2028. This licence period will cover the time required to complete the refurbishment of all four Darlington reactor units.
OPG undertook an Environmental Assessment (EA) for the refurbishment and continued operation of the four Darlington reactors. Following a detailed technical review of the work and a four-day public hearing, the CNSC agreed there would be no significant adverse environmental effects given available mitigation actions. This decision challenged and later upheld by a federal court.
Integrated Safety Review
An Integrated Safety Review (ISR) is a systematic assessment of the existing plant to determine if it conforms to modern standards and practices, and whether adequate arrangements are in place to maintain plant safety for long-term operation. Darlington’s ISR demonstrates the plant meets modern codes and standards and uses industry best practice.
Integrated Implementation Plan
The Darlington Integrated Implementation Plan (IIP) outlines the scope and timeframes to implement the safety improvements resulting from the EA and ISR. Major activities include:
- replacing fuel channels, feeder pipes, calandria tubes and end fittings;
- installing safety improvement projects; and
- undertaking a Global Assessment Report.
A Global Assessment Report (GAR) is an overall risk judgment on the acceptability of continued plant operations. Darlington’s GAR demonstrates the plant is is safe and reliable. The planned safety improvements will ensure its continued safety and reliability.

Two independent oversight organizations have been established: one reports to the Project Executive and the OPG Board of Directors (Burns & McDonnell/Modus); and a second, reports directly to the Ontario Ministry of Energy.
