Job description

Our Thermalhydraulics & Safety Analysis branch is looking for a Thermalhydraulics Analyst! Can you see yourself in a role where you will join an experienced team to carry out cutting-edge research to enhance nuclear safety? If so, apply today.

What will you be doing!

• Contributing to the development and qualification of (system and/or sub-channel) thermalhydraulics codes or coupled codes for CANDU and small modular reactors (SMRs).
• Contributing to reactor safety research as part of a multi-disciplinary team in areas such as thermalhydraulics (both experimental and modelling & simulation), reactor physics, and severe accidents.
• Managing Federal Science & Technology (FST), Laboratory-Directed Science & Technology (LDST) and CANDU Owners Group (COG) projects or tasks on an as-required basis, ensuring deliverables and milestones are achieved on time and on budget.
• Other duties as assigned by your manager.

What we are looking for:

• Education
  • An advanced degree (M.Sc. or Ph.D.) in Engineering (e.g., Nuclear / Mechanical / Chemical / Industrial or similar) or Science from a university of recognized standing; or membership in an engineering or scientific professional organization authorized by statute to establish qualification for membership in that organization.
• Experience
  • Background in numerical methods, single- and two-phase fluid flow and heat transfer.
  • Experience in conducting thermalhydraulic experiments, and/or in the development and application of system thermalhydraulics and/or sub-channel thermalhydraulics and/or CFD codes (e.g., ARIANT, CATHENA, RELAP5-3D, TRACE, ASSERT, COBRA-TF, STAR-CCM+) to model CANDU and/or advanced reactors including small modular reactors (SMR).
  • Experience in the use of workstations, high-performance computing clusters, associated operating systems (Windows, Linux, etc.) and software applications (e.g., MS-Office).
• Knowledge, Skills & Abilities
  • Knowledge of FORTRAN programming language & scientific programming, code development, code validation and software quality assurance is desirable.
  • Knowledge of reactor safety & defense-in-depth, and sensitivity and uncertainty analysis methodology is desirable.
  • General knowledge of CANDU reactors and/or advanced reactors (e.g. High Temperature Gas Cooled Reactors, Molten Salt Reactors, Boiling Water Reactors, Heat Pipes, and Fusion Reactors) would be an asset.
  • A proven track record in the publication of technical papers and reports.
  • Excellent technical writing, oral communication, and interpersonal skills.
  • Demonstrated ability to effectively present work to expert and non-expert audiences.
  • Motivated and able to work independently and collaboratively.
• Security Clearance Eligibility Required
  • Reliability Status with Site Access Security Clearance (SASC), which has a minimum requirement of 3 years of verifiable history in Canada, Australia, New Zealand, the United States and/or the United Kingdom. CNL implements security screening in accordance with the Treasury Board of Canada Secretariat's “Standard on Security Screening” and the “Policy on Government Security.”
