Senior Technical Specialist, SMR/Non-Standard Fuel Wastes

The Nuclear Waste Management Organization (NWMO) is a not-for-profit organization tasked with the safe, long-term management of Canada’s used nuclear fuel inside a deep geological repository, in a manner that protects people and the environment for generations to come.

Founded in 2002, the NWMO has been guided for 20 years by a dedicated team of world-class scientists, engineers and Indigenous Knowledge Keepers that are developing innovative and collaborative solutions for nuclear waste management. Canada’s plan will only proceed in an area with informed and willing hosts, where the municipality, First Nation and Métis communities, and others in the area are working together to implement it. The NWMO plans to select a site in 2024, and two areas remain in our site selection process: the Wabigoon Lake Ojibway Nation-Ignace area in northwestern Ontario and the Saugeen Ojibway Nation-South Bruce area in southern Ontario.


Senior Technical Specialist, SMR/Non-Standard Fuel Wastes

Regular Full-time

Position Location: Toronto Head Office – 22 St. Clair Avenue East


Job Summary:

Reporting to the Director, Safety & Technical Research the incumbent will provide technical design input and oversight to the support the assessment of SMR and non-standard CANDU nuclear waste forms, for their inclusion in the Adaptive Phased Management (APM) deep geological repository safety case. 

The incumbent will be responsible for developing directly or via contracts the understanding needed to support engineering design and safety assessment of SMR and non-standard nuclear waste forms.  Assessment of criticality safety topics will be a specific focus, but the work also includes: dimensions and amounts; heat generation, waste form durability; corrosion; radionuclide content; and radionuclide release.
