Experts with the Nuclear Waste Management Organization are adjusting their forecasts for the Ignace area, so they include the possibility of more rainfall. The adjustment will allow for climate change, including the possibility of extreme weather and increased flooding.

“This is the first time this modelling work has been done for a potential repository location and any assessment of sites for the safe storage of used nuclear fuels must take into account the potential future impact of climate change on its infrastructure,” said Kelly Liberda, who is a senior engineer with NWMO, who are working on the site selection process.

“While it’s difficult to project the extent to which precipitation could fluctuate in specific geographic areas, the NMWO is taking steps to anticipate the most likely scenarios,” Liberda added.

Based on a multi-model assessment of publicly available data, the Golder Associates study found that both one-day probable maximum precipitation and one-day rainfall events in the Ignace study area are projected to increase in the 2050s and 2080s. 

Ignace is one of two finalists for a nuclear waste repository. The other is South Bruce, and a final decision on the location isn't expected before 2023.
