Nuclear Safety Engineer
The job description
Tech stack. PRA software (SAPHIRE, CAFTA), deterministic safety analysis, 10 CFR 50.46 and Appendix K, event tree and fault tree methods, thermal-hydraulic codes, Python for data analysis, human reliability analysis
About the role
You will prove the plant is safe for a nuclear utility or design organization, performing the deterministic and probabilistic analyses that underpin the licensing basis. The team evaluates design-basis accidents, quantifies risk with probabilistic models, and ensures safety systems perform when demanded. You will build fault trees, analyze transients, and document results that regulators scrutinize line by line. This role matters because your analyses are the technical foundation of the license itself, and the conservative rigor you apply protects the public every single day. You will also support the plant's response to NRC generic communications, evaluating whether industry operating experience applies to your facility. Your risk insights will guide the prioritization of engineering resources toward the modifications that reduce risk most. You will maintain the safety analysis code inputs under strict configuration control, because an analysis is only as trustworthy as its inputs. Your presentations to senior leadership will translate complex accident phenomenology into clear decisions about plant investments.
What you will achieve
- Complete deterministic safety analyses for design-basis events with all acceptance criteria met and results independently verified.
- Maintain and update the plant PRA model, keeping it current with design changes and reflecting actual plant configuration.
- Support license amendment requests with safety evaluations the NRC accepts without major rounds of questions.
- Quantify the risk significance of proposed plant changes, enabling risk-informed decision-making across engineering.
- Deliver training to operations staff on accident phenomenology that measurably improves simulator drill performance.
What you will bring
Must-haves
- 2 to 5 years in nuclear safety analysis, PRA, or a closely related analytical role.
- Understanding of deterministic safety analysis methods and 10 CFR 50.46 acceptance criteria.
- Experience with PRA techniques: event trees, fault trees, and human reliability analysis fundamentals.
- Familiarity with thermal-hydraulic phenomena in accident sequences and how codes model them.
- Ability to write safety analysis reports meeting regulatory quality and documentation standards.
- Conservative engineering judgment: you question assumptions and bound uncertainties properly.
- Comfort defending analyses under challenging regulatory or peer review questioning.
Nice-to-haves
- Experience with SAPHIRE, CAFTA, or equivalent PRA software platforms.
- Knowledge of severe accident phenomena and mitigation strategies.
- Familiarity with risk-informed applications such as 10 CFR 50.69 or technical specification changes.
- Advanced degree in nuclear engineering with safety analysis focus.
