About The Position

The Thermal-Hydraulics Engineer 2 reports to the Manager, Thermal Hydraulics and works collaboratively with Nuclear Methods, Nuclear Design, and Code Development teams within the broader Nuclear Fuels department, as well as with other Engineering disciplines and Operations functions. This position is an engineer with experience in nuclear thermal-hydraulic analyses, codes, and methods, as well as familiar with interfaces with core design and neutronics. This role will apply industry best-practices to perform system level thermal hydraulic analysis and subchannel analysis supporting development of the SMR product, reload safety analysis, and customer-specific application of codes and analysis methods. The role requires familiarity with PWR thermal hydraulic principles, design basis safety analysis, and interfaces with core design, fuel design, neutronics, and transient analysis.

Requirements

• A minimum of B.S. degree in Nuclear, Mechanical, or Chemical Engineering (or related discipline) from a four-year accredited college or university is required.
• A minimum of 3 years of full-time, directly relevant engineering experience is required.
• Experience in implementing engineering design processes for subchannel thermal-hydraulics, transient analysis, or related safety analysis is required.
• Eligible to work under Department of Energy 10 CFR Part 810.

Nice To Haves

• Advanced degree in Nuclear, Mechanical, or Chemical Engineering is desirable.
• Experience in neutronics or fuel performance preferred.

Responsibilities

• Executes VIPRE subchannel evaluations including CHF predictions and thermal margin calculations in accordance with approved methods. Maintains subchannel models and ensures correctness of inputs, correlations, and boundary conditions.
• Conducts RELAP analyses for LOCA, non-LOCA transients, and other design basis scenarios in accordance with approved methods. Document model setup, assumptions, and results in accordance with approved requirements.
• Contribute to assessments of system behavior and protective features in the context of safety analysis acceptance criteria. Identifies potential design impacts on thermal hydraulic margins and communicates findings.
• Supports cross functional thermal hydraulic reviews for reload safety analyses, plant design changes, operational concepts, and licensing deliverables. Evaluates margin sensitivities and interface impacts of design changes.
• Works collaboratively within the Nuclear Fuels organization to ensure design and analysis interfaces are adequately managed. Communicates technical inputs clearly and ensures boundary conditions and assumptions are aligned.
• Contributes to technical development of licensing technical or topical reports, license applications, and other licensing documentation.
• Prepares and verifies engineering reports, calculations, studies, system descriptions, requirement specifications, and other design documents with particular emphasis on subchannel and system thermal-hydraulics.
• Develops resolutions to challenging problems that require the use of creativity and innovation.
• Performs other duties as assigned. Flexibly supports changing organizational priorities, including urgent analysis needs, cross functional reviews, technical troubleshooting, or special studies.

Benefits

• The target pay range for this position is $87,107 - $105,129 annually. The full pay range is $78,096 - $122,149 annually.
