MCRE, Senior Probabilistic Risk Assessment Engineer

Location: Bellevue,Washington,United States

TITLE:                  Senior/Principal Probabilistic Risk Assessment Engineer

LOCATION:         Bellevue, WA, USA

TerraPower is a nuclear technology company based in Bellevue, Washington. At its core, the company is working to raise living standards globally through a more affordable, secure and environmentally friendly form of nuclear energy along with innovations in medical isotopes to improve human health. In 2006, TerraPower 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. TerraPower’s mission is to be a world leader in new nuclear technologies, while developing innovators and future leaders in the nuclear field. As a result, the company’s 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 – all for significant human health benefits.

TerraPower is seeking to hire highly motivated and forward-thinking professionals who are interested in focusing on advanced nuclear reactor research and development and influencing change within the nuclear power landscape and bringing forward the critical production of medical isotopes.  TerraPower is an Equal Opportunity Employer. We do not discriminate in hiring on the basis of sex, gender identity, sexual orientation, race, color, religious creed, national origin, physical or mental disability, protected Veteran status, or any other characteristic protected by federal, state, or local law. In addition, as a federal contractor, TerraPower has instituted an Affirmative Action Plan (AAP) in an effort to proactively recruit, hire, and promote women, minorities, disabled persons and veterans.

Senior/Principal Probabilistic Risk Assessment Engineer

The Senior/Principal Probabilistic Risk Assessment (PRA) Engineer is responsible for Level-1 and/or Level-2 PRA supporting the design of reactors under development of the Molten Chloride Fast Reactor (MCFR) Program, specifically this will focus on the further development of the PRA to support the Molten Chloride Reactor Experiment (MCRE).

Other engineering activities include, but are not limited to, contributing to the development of computational methodologies and models, participating in hazard analysis, participating in Phenomena Identification and Ranking Table (PIRT) exercises, and participating to Structures, Systems, and Components (SSC) classification, Safety Basis Events (SBE) selection, and Defense-in-Depth (DID) Evaluations. The Senior/Principal PRA Engineer will be interacting with other groups via interviews, emails, meetings, and other avenues to develop the risk models and the position requires sound written and verbal communication skills.

The Senior/Principal Probabilistic Risk Assessment Engineer receives administrative and technical supervision from the Nuclear Safety Discipline Manager. Actual level will be based on candidates experience

Responsibilities

•         Manage PRA work performed inside and outside of TerraPower in coordination with plant design, deterministic safety analysis, and other disciplines.

•         Ensure that the PRA is appropriate and used for the reactor design and within regulatory requirements, guidance, and standards such as risk-informed performance-based technology guidance for Non-Light Water Reactors (RG 1.233 and NEI 18-04) and ASME/ANS Non-Light Water PRA standard.

•         Develop containment fault trees and event trees to reflect most up to date design using CAFTA.

•         Group similar source terms for assignment to event sequence end states.

•         Perform risk integration using the PRA model to report risk metrics and importance measures.

•         Perform focused PRA analysis to support trade studies.

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

•         Provide technical guidance to engineers and managers on reliability and various PRA-related topics.

•         Establish and maintain documentation of model development and analysis results.

•         Perform engineering reviews of analyses and other engineering design media.

Key Qualifications and Skills

•         B.S. in nuclear, mechanical, electrical, or aerospace engineering (or similar), with a minimum of 5 years’ expe
