Senior Core Thermal Hydraulic Engineer

Holtec International is seeking multiple Core Thermal Hydraulics (T/H) Engineers experienced in performing core T/H analysis to work on the development and licensing of the SMR-160 design.  The core T/H engineers are responsible for the development and application of core T/H analysis methodologies for the SMR-160 reactor core. Primary work includes design, modeling, and analysis of reactor performance during steady-state and transient scenarios for this passive, integrated light water reactor. Principal modeling and analysis tools include COBRA, VIPRE, TRACE, RELAP, etc.

The SMR-160 Reactor Core Engineering (RCE) group is responsible for developing analytical methods and analyses used to design and license the Holtec International SMR-160 Nuclear Power Plant (NPP). RCE personnel perform reactor core analyses of anticipated transients to demonstrate that the SMR-160 meets or exceeds its safety basis and NRC licensing requirements. RCE design and analysis work addresses aspects of reactor performance that include a wide range of physical phenomena, including nuclear, thermal hydraulic, heat transfer, transient kinetics, two-phase flow, reactor protection system setpoints and methodologies, and plant control system functions. RCE personnel also perform validation and benchmarking of the analytical tools to demonstrate their applicability to the SMR-160 design.

Specific Areas of Responsibility:

Develop analytical models and input decks for the design and analysis of the SMR-160 core.
Perform code benchmarking and validation to support code qualification and methodology development.
Support the design and analysis of test data for the development of thermal performance criteria for the SMR-160 system.
Support the development of T/H analysis methodologies to support safety analysis of transient and postulated accident scenarios related to the SMR-160.
Contribute to topical reports for NRC review and approval that describe how the suite of T/H codes will be applied along with inputs, models, and correlations to establish the design basis transients and accident analyses.
Integrate with other engineering groups performing aspects of component, system, fuel, and control system design.

Minimum Requirements:

B.S. or M.S. in nuclear engineering, mechanical engineering, or chemical engineering (or closely related field) from an accredited college or university.
Seven to ten years of experience in core T/H analysis (M.S. degree equivalent to 2 years of experience).
Strong T/H analytical skills including at least three years of experience with COBRA, VIPRE or other T/H sub-channel analysis code package.
Demonstrated technical writing skills through FSAR, DCD, or responses to RAIs
Demonstrated effective communication skills.
Eligible to work under Department of Energy 10 CFR Part 810.

Desired Qualifications:

M.S./Ph.D. in nuclear engineering, mechanical engineering, or chemical engineering.
Fifteen years of experience in core T/H and safety analysis.
Ten years of experience in T/H sub-channel analysis.
Comprehensive knowledge of NUREG-0800 (NRC Standard Review Plan for LWRs) Chapter 4 and 15 requirements.
