Fuel Fabrication Criticality Analysis & Nuclear Safety Engineer

Role overview

Develop and maintain the criticality safety basis and broader nuclear safety analyses for facilities that fabricate advanced nuclear fuel. The role spans computational analysis, facility and process design reviews, safety controls, licensing support, and readiness for commissioning and operations, in close coordination with engineering, operations, licensing, and quality teams.

Responsibilities

- Prepare Criticality Safety Evaluations and supporting calculations, using neutron transport tools such as MCNP, SCALE, or SERPENT. - Analyze hazards and accident scenarios, and define controls for fissile material operations, including mass limits, geometry, moderation, and administrative measures. - Review facility layouts, equipment, and process designs for nuclear safety, including work on uranium and other advanced fuel materials. - Support licensing documentation and responses to regulatory requests, and maintain safety basis documentation and criticality alarm requirements. - Participate in HAZOPs, What-If reviews, FMEAs, and design reviews; assist with startup testing, readiness reviews, and commissioning. - Investigate abnormal conditions and recommend corrective actions while supporting compliance with applicable nuclear safety requirements.

Requirements

- Bachelor’s degree or higher in nuclear engineering or a closely related field. - Experience performing nuclear criticality or safety analyses, with knowledge of neutron transport and computational modeling. - Understanding of applicable nuclear safety requirements and criticality safety principles, including ANSI/ANS-8 standards. - Ability to assess complex process systems and identify credible accident scenarios. - Strong technical writing and presentation skills, and ability to work across engineering and operations disciplines. - Typically, 3–10+ years of relevant analysis experience in fuel cycle, reactor, government, national laboratory, or another highly regulated nuclear setting.

Nice to have

- Graduate degree in nuclear engineering; experience with fuel fabrication involving HALEU, plutonium, or uranium. - NRC licensing analysis experience, familiarity with DOE-STD-3007 or NQA-1, or work with HAZOPs, accident analysis, or probabilistic risk assessment.

Benefits and work setup
