Nuclear Waste Management Facility Performance Report - Q1 2024 Results

Accent: 9eac1lbr8fd3

Performance update

As part of our commitment to keep you informed, this report tracks performance for Ontario Power Generation’s (OPG's) Nuclear Waste Management facilities in the areas of safety, operations, and the environment. It also summarizes significant accomplishments achieved during the first quarter of 2024.

OPG operates three nuclear waste facilities across the province located in Darlington, Pickering & Bruce County. Spent fuel taken from the reactors is stored at each facility locally after it has been cooled for 10 years. Low and intermediate level materials are stored at OPG’s Western Waste Management Facility.

Safety

Total Reportable Injury Frequency (TRIF)

TRIF is a measure of the number of injuries involving OPG employees that result in a fatality, lost time, restricted work or medical treatment per 200,000 hours worked. Q1 TRIF is at 0.00. The year-end target is not to exceed 0.47. OPG measures TRIF using a 12-month rolling average, rather than quarterly updates.

Transportation Safety

Experienced and skilled drivers manage the transportation of waste to our Western facility from Darlington, Pickering and Bruce Power. In this quarter, all shipments were made safely and accident-free and the fleet safely travelled 154,990 additional kilometres this quarter marking over 6.75 million kilometres safely travelled to-date.
