Thermalhydraulics Analyst
Apply NowCompany: Canadian Nuclear Laboratories
Location: New Canada, NS B4V 4V5
Description:
Our Thermalhydraulics & Safety Analysis branch is looking for a Thermalhydraulics Analyst!
INTRO
The Thermalhydraulics & Safety Analysis Branch is responsible for the development and application of computer codes and analysis tools (e.g. ARIANT, ASSERT-PV) in support of design and safety analysis of current reactors such as CANDU and light water reactors, as well as innovative Small Modular Reactors (SMRs). Capabilities in the areas of fluid dynamics, heat transfer, reactor physics, and fission product release are applied to safety assessments for design-basis, beyond-design-basis accidents, and severe accidents. The branch conducts both Deterministic and Probabilistic Safety Assessments to evaluate safety margins and the likelihood of postulated accidents. Major expertise areas of the branch include system thermalhydraulics, sub-channel thermalhydraulics, computational fluid dynamics (CFD), multi-physics multi-scale modelling, safety analysis and uncertainties, severe accident modelling, and advanced reactor technology development. The branch's comprehensive modelling and analysis capability supports CNL's commitment to advancing reactor safety and informing the design of next-generation nuclear technologies.
A Thermalhydraulics Analyst is needed to join our experienced team and carry out cutting-edge research to enhance nuclear safety. The initial focus will be to develop code development skills and become a member of the sub-channel thermalhydraulics (ASSERT-PV) code development team to support CANDU and SMRs. Over time the incumbent is expected to develop in-depth knowledge and become an expert in one or more of the major expertise areas in the branch.
If you have an advanced degree (or within 6 months of completing your program) in a relevant field and are interested in pursuing a career in nuclear, we would like to hear from you.
What will you be doing!
Reporting to the Manager of Thermalhydraulics & Safety Analysis Branch, the incumbent has the following responsibilities:
Contribute to the development and qualification of (sub-channel and/or system) thermalhydraulics codes or coupled codes for CANDU and small modular reactors (SMRs).
Contribute 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.
Manage 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:
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.
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-PV, COBRA-TF, STAR-CCM , OpenFOAM) to model CANDU and/or advanced reactors including small modular reactors (SMR) would be a significant asset.
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 track record in the publication of technical papers, articles 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.
Experience in the use of workstations, high-performance computing clusters, associated operating systems (Windows, Linux, etc.) and software applications (e.g., MS-Office).
Security clearance eligibility required: Reliability Status 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."
Why CNL?
Does working with a team across Canada to advance nuclear science and technology for a clean and secure world speak to you? We're reinventing ourselves to be the pacesetters so we can lead the charge in solving the problems that matter, like building the next generation of clean nuclear and hydrogen energy solutions, developing new and better-targeted cancer treatments, and continuing to lead the world in environmental remediation.
We offer a complete total rewards package :
paid time off (vacation, sick, floater & personal);
benefits effective day one, that's right, no waiting period;
tuition support
and a pension!
Do Our Priorities Resonate with You?
Clean energy for today and tomorrow.
Restore and protect the Environment.
Contribute to the health of Canadians.
Location:
CNL works with employees across our Canadian locations to enable remote work when possible. This role requires regular work at CNL's Chalk River Laboratory site while also permitting the employee to spend the majority of their time working remotely, should they so desire. CNL employees who choose to work remotely the majority of the time are provided with the equipment required to be successful at their remote workplace (laptop, chair, monitor, etc.); however, they are not provided a dedicated onsite office. CNL's Chalk River laboratory is nestled in the Ottawa Valley and affords our employees an area that is environmentally pristine with extensive forests, hills and numerous small lakes, all of which support a variety of wildlife typical to the southern edge of the Canadian Shield. Many surrounding towns, such as Pembroke, Petawawa and Deep River, provide you with unparalleled outdoor adventures at your doorstep! In fact, Deep River was recently named the fourth best place to live in Canada by movingwaldo.com.
CNL is committed to providing an atmosphere free from barriers that promotes equity, diversity and inclusion in achieving our mission. CNL welcomes and celebrates employees, stakeholders and partners of all racial, cultural, and ethnic identities. Read here further on our DE&I Commitment.
CNL also supports a workplace environment and a corporate culture that is built on our Core Values: Respect, Teamwork, Accountability, Safety, Integrity and Excellence which encourage equitable employment practices and career prospects inclusive of accommodations for all employees.
CNL is committed to being an equal-opportunity employer. If you require accommodation measures during any phase of the hiring process, please indicate via our ATS when applying. All information received in relation to accommodation requests will be kept confidential.
The Chalk River Laboratories site is located on the unceded and unsurrendered territory of the Algonquin Anishinaabe people. As an organization, CNL recognizes and appreciates their historic connection to this place. CNL also recognizes the contributions that First Nations, Mtis, Inuit and other Indigenous Peoples have made, both in shaping and strengthening this community in particular, and this province and country as a whole.
