Principal Thermal-Hydraulics & Safety Analysis Engineer

What you'll do

• Own system and subchannel thermal-hydraulics modeling, including LOCA, natural circulation, DNBR, and hot-channel analysis.
• Size reactor coolant system components and establish heat balances and flows across primary, secondary, and tertiary loops.
• Author Chapter 15 transient and accident evaluations and coordinate safety analyses with the broader risk-informed safety case.

What they ask for

• MS or PhD in Nuclear or Mechanical Engineering, specializing in reactor thermal-hydraulics or pressure-vessel design.
• Hands-on experience running system thermal-hydraulics codes and subchannel codes for MDNBR and hot-channel evaluation.
• Deep understanding of ASME Boiler & Pressure Vessel Code, Section III, Division 1, Subsection NB (Class 1).
• Ability to size steam generators and heat exchangers from heat balances and reactor pressure-vessel walls using membrane hoop thickness formulas.

Nice to have

• Experience designing loop components for marine or compact-PWR environments; familiarity with ANSYS or ABAQUS structural FEA.
• Knowledge of 10 CFR 50 Appendix G, marine dynamic loading, and integrating Chapter 15 results with PRA.
