Seminar Series: Dr Sarah Hirschorn – Characterizing Sites for a Deep Geological Repository for Canada’s Used Nuclear Fuel

January 14 @ 12:00 pm - 1:00 pm

Characterizing Sites for a Deep Geological Repository for Canada’s Used Nuclear Fuel

The Nuclear Waste Management (NWMO) is responsible for implementing, collaboratively with Canadians and Indigenous people, Canada’s Plan for the safe, long-term management of used nuclear fuel. Made up of engineers, technical experts, social scientists and engagement professionals, the NWMO is working to implement Canada’s plan, in a manner that protects both people and the environment. Canada’s plan calls for containment and isolation of used nuclear fuel in a deep geological repository, which is made up of a series of natural and engineered barriers. This facility will be located in an area with informed, willing hosts and a suitable rock formation. The NWMO is on track to identify a single, preferred location for this facility by approximately 2023.

This presentation focusses on the geoscientific aspects of site characterization as the NWMO studies the remaining sites in increasingly more detail.

Sarah started at the Nuclear Waste Management Organization in 2008 as a geochemist, working with both the site evaluation and the research and development programs associated with Adaptive Phased Management, Canada’s approach for long-term management of used nuclear fuel.

In her current role, she is responsible for the NWMO’s geoscientific site investigations activities, as we continue to assess the suitability of potential sites for hosting a deep geological repository.

Sarah obtained her bachelor’s and doctorate degrees in Geology from the University of Toronto.
