Job Description
KeySource Thomas Thor has been engaged by Canadian Nuclear Laboratories (CNL) to fill several Senior Material Scientist roles at their Chalk River Laboratories in the upper Ottawa Valley.  CNL is Canada’s premier nuclear science and technology organization, serving Canada as an enabler of business innovation and technology transfer.  While viewed as a world leader in developing peaceful and innovative applications from nuclear technology through its expertise in physics, metallurgy, chemistry, biology, and engineering, CNL is committed to ensuring that Canadians and the world receive energy, health, and environmental benefits from nuclear science and technology.

Role description

The Materials & Mechanics Branch performs metallurgical examinations, material surveillance and cracking experiments of irradiated and un-irradiated reactor materials. The capabilities of the branch include failure analysis, fracture mechanics, delayed hydride cracking, environmentally assisted cracking and material surveillance. As a member of the Materials and Mechanics Branch, the selected candidate will work with a team of experienced Professional and Technical staff responsible for R&D, principally in the area of nuclear reactor material. This will involve the development of test programs through participation in industry-wide working groups. Programs will include testing of removed reactor components as well as development and testing of laboratory-controlled specimens. In addition, he/she is expected to enhance the fundamental understanding of material properties for irradiated materials. Most of the work will include participation in contract R&D for third parties. As such, the candidate will be expected to work with industry groups to confirm, expand or revise the property databases used in reactor fitness-for-service guidelines.


The R&D Material Scientist will report to a Section Head within the Materials & Mechanics Branch, and have the following responsibilities:
  • Define the mechanical testing of irradiated pressure tube and other materials,
  • Define the mechanical testing of unirradiated materials,
  • Development of new material testing concepts,
  • Establish the required measurement parameters including calibrations and acceptance criteria for testing,
  • Lead complex research projects in the area of material science,
  • Supervise junior engineering and technical staff,
  • Evaluate the mechanistic understanding of materials (metals) behavior,
  • Prepare various technical documents, including test reports and assessment reports, analysis reports,
  • Project management of research projects,
  • Overall technical responsibility for various aspects of pressure tube surveillance work,
  • Provides novel solutions to problems,
  • Resolves complex multi-disciplinary problems,
  • Influences company’s strategic technical direction,
Essential skills
  • PhD in Engineering or Material Science or related disciplines.
  • A minimum of 12 years of experience in the area of material science, fracture mechanics, material modelling, and experimental techniques.
  • A strong knowledge of mechanical testing, corrosion, fatigue, stress corrosion cracking or welding.
  • BWR and/or PWR experience
  • Knowledge in failure analysis, fractography, weld microstructures, ferrous metallurgy and nickel alloys would be beneficial.
  • Should have the experience in managing technical projects and supervise junior engineering, technical, and administrative staff.
  • Experience in design/development of new experimental method/ test rigs for material testing would be an asset.
  • Experience with testing of irradiated materials would be an asset.
  • Experience using advanced characterization tools such as FIB, TEM, EBSD, nano-indentation would be an asset.
  • Good organizational and work planning skills is essential.
  • Strong negotiation and communication skills to manage and motivate a team of professional and technical staff.
  • Ability to work in a team environment, maintains a clear focus on team goals, and establishes good rapport with groups and individuals of many diverse professions.
  • Skilled in preparation of cost estimates for research projects, and management of projects including scope schedule and budget management.
  • Excellent written and oral communications skills.
  • Demonstrated publication history.
Desired skills
  • General knowledge of zirconium alloys would be beneficial.
  • Knowledge of the nuclear design codes & standards (ASME, CSA) would be an asset.
  • Familiarity with preparing and executing commercial proposals would be beneficial.
