Full Job Description

Job Title: System Transients Analysis Engineer
Location: Bellevue, WA
Job Type: Contract
Work Model: Hybrid/Onsite Preferred

Overview

System One is seeking a highly capable and motivated System Transients Analysis Engineer to support an advanced sodium-cooled reactor program. This role will focus on thermal hydraulic and transient analysis activities supporting advanced reactor system design, plant operations analysis, and control system integration.

The ideal candidate will have strong experience with system analysis codes such as RELAP5 or TRACE, along with a strong foundation in thermal hydraulics, heat transfer, fluid dynamics, and nuclear plant transient analysis.

Responsibilities

Develop RELAP5-3D models for steady-state and transient one-dimensional hydraulic network analyses
Perform reactor and plant transient analyses for normal operations, upset conditions, emergency events, and faulted scenarios
Develop plant-level control strategies and component-level controllers
Perform calculations using first principles of heat transfer, thermodynamics, and fluid dynamics to validate analytical results
Support evaluation of plant-wide transients, operational narratives, and design solutions
Perform multiscale and multidisciplinary thermal hydraulic analyses involving sodium, molten salt, and non-condensable fluids
Collaborate closely with safety, I&C, design engineering, and testing teams
Support development of new analytical methods and advanced modeling techniques
Prepare technical reports, calculations, and engineering documentation

Required Qualifications

Bachelor’s degree or higher in Nuclear Engineering, Mechanical Engineering, Electrical Engineering, or related discipline
Strong experience with thermal hydraulic system codes such as RELAP5 and/or TRACE
Strong analytical background in:
- Thermal hydraulics
- Fluid dynamics
- Heat transfer
- Transient analysis
- One-dimensional hydraulic network modeling
Strong technical writing and communication skills
Ability to work effectively in a collaborative, fast-paced engineering environment
High level of professionalism, integrity, and teamwork

Preferred Qualifications

Experience with ASME component design and analysis
Experience modeling control systems and Instrumentation & Controls (I&C)
Experience supporting nuclear power plant design or operations
Experience developing new analytical methods
Advanced reactor or sodium-cooled reactor experience

Physical & Work Environment Requirements

Ability to sit and/or stand for extended periods
Minimal lifting requirements up to 25 pounds
Prolonged computer and keyboard work
Standard office or engineering work environment
Occasional travel up to 5%
