TITLE: Principal Safety Analysis Engineer

LOCATION: Bellevue WA USA

TerraPower is a nuclear energy technology company based in Bellevue Washington. At our core we are working to raise living standards globally. The essential factor 2006 the company originated with Bill Gates and a group of like-minded visionaries who evaluated the fundamental challenges to raising living standards around the world. They recognized energy access was crucial to the health and economic well-being of communities and decided that the private sector needed to take action and create energy sources that would advance global energy deployment. TerraPowers mission is to be a world leader in new nuclear technologies while developing innovators and future leaders in the nuclear field. TerraPower is committed to bringing sustainable affordable and safe energy to address global issues. As a result the companys activities in the fields of nuclear energy and related sciences are yielding significant innovations in the safety and economics of nuclear power hybrid energy and medical applications.

Principal Safety Analysis Engineer

The Principal Safety Analysis Engineer is primarily responsible for performing accident analyses of reactors under development by the Sodium Fast Reactor (SFR) Program. Other engineering activities include but are not limited to supporting design transients analysis contributing to the development of computational methodologies and models participating in Structures Systems and Components (SSC) classification developing analytical methods as well as supporting uncertainty quantification and sensitivity calculation.

Under TerraPowers matrix organizational structure the Principal Safety Analysis Engineer receives administrative and technical supervision from the Nuclear Safety Discipline Principal Manager and Managers and project direction from project managers.

Responsibilities

Develop SFR system models and perform safety analysis for the Natrium Demonstration reactor for Anticipated Operational Occurrence (AOO) Design Basis Event (DBE) and Design Basis Accident (DBA).

Work with an interdisciplinary team of engineers to establish core and reactor SSC functional performance safety and quality requirements as well as support the overall design.

Contribute to the safety methods development such as code assessment scaling analysis code verification and validation activities etc.

Establish and maintain documentation of model development and analysis results.

Perform engineering reviews of analyses and other engineering design media.

Assess available plant transient benchmark tests identify applicable tests based on the relevance to the design being pursued by the SFR Program and perform appropriate benchmark calculations.

Contribute as needed to the implementation of capabilities required for transient and accident analysis within the TerraPower software framework.

Key Qualifications and Skills

Extensive experience in nuclear safety analysis modeling nuclear reactor system in computer code perform analysis using Best Estimate Plus Uncertainty (BEPU) approach and/or computer code development.

Significant experience with safety analysis software such as RELAP5 TRACE TRAC SAS4A/SASSYS-1 or other nuclear system analysis software.

Experience of performing transient and accident analysis for submittals to NRC such as Chapter 15 in the Final Safety Analysis Report (FSAR) is highly desired.

Knowledgeable of nuclear systems thermal-hydraulic fundamentals as well as reactor dynamics and transient phenomena.

Knowledgeable of nuclear reactor core physics such as neutron transport theory and reactivity feedback.

Knowledgeable of nuclear reactor instrumentation and control systems and related modeling approaches in the safety analysis computer code.

Familiarity with nuclear design regulatory requirements and risk-informed performance-based technology guidance for Non-Light Water Reactors is required.

Familiarity with EMDAP and Regulatory Guide 1.203 is preferred.

Experience with SFR safety analysis or methods is highly desirable. Experience with other reactor designs such as Light Water Reactors (LWRs) can be considered when differentiating candidates.

Demonstrated strong quantitative analytical modeling and reporting skills.

Understanding NQA-1 requirements associated with analysis and software management as well as experience working under a quality assurance program.

Experience in working in multi-disciplinary engineering teams to address engineering challenges.

Strong software engineering skills in any language such as Python Fortran or C is a plus.

B.S. M.S. or Ph.D. in nuclear engineering or other relevant engineering degree with a minimum of 5 years experience in the nuclear field.

The successful candidate will possess a high degree of trust and integrity communicate openly and display respect and a desire to foster teamwork.
