Principal Nuclear Safety Analyst

Information Systems Laboratories, Inc. (ISL) is an employee-owned technology-development company specializing in comprehensive support for the nuclear and space industries, including nuclear safety analysis, complex modeling & simulation, software development, regulatory frameworks, waste management, risk management, and cyber security.

About the role

The Principal Engineer will work alongside safety analysis experts performing a mix of research and development and customer contract work. Customers are primarily advanced reactor and fuel vendors requiring ISL’s expertise to meet licensing requirements of the U.S. NRC or DOE. The role involves modeling and simulation of system and core thermal-hydraulics, nuclear physics, fuel performance, and radiological consequences using tools such as RELAP5-3D, TRACE, VIPRE-01, MCNP, SCALE, PARCS, FAST, and RADTRAD.

Responsibilities include hazard analysis, safety basis event identification, model and simulation development, transient analyses, and safety basis documentation for existing LWR, SMR, and advanced reactor designs. The position also involves writing technical reports, white papers, creating presentations, and communicating ideas, problems, and solutions. Opportunities to advance the state-of-the-art, publish research, present at conferences, and develop industry contacts are available.

Requirements

• Degree (B.S or M.S.) in Nuclear or Mechanical Engineering;
• 15-20 years of experience in nuclear;
• Prior safety analysis and/or reactor design experience;
• Self-starter with the ability to work well within a team or independently;
• Demonstrated ability to solve complex problems and adapt to changing situations;
• Drive to verify results and ensure they make sense;
• Experience with fluid dynamics, heat transfer, nuclear physics, and/or structural mechanics;
• Experience with RELAP5-3D or TRACE;
• Experience with U.S. NRC licensing (NUREGs, Reg. Guides, etc.);
• Experience with safety basis events, categories, and transient analysis;
• Familiarity with historic, operating, and advanced nuclear reactors.

Desired Skills

• Understanding of the fundamentals of nuclear physics;
• Familiarity with nuclear quality assurance (ASME NQA-1);
• Familiarity with U.S. DOE authorization basis;
• Experience with design basis accident dose analysis;
• Experience with radiation shield design and modeling & simulation;
• Experience with general calculation software such as Mathcad and/or Octave;
• Experience with nuclear physics codes such as MCNP, SCALE, PARCS, etc.;
• Experience with CFD and Multiphysics codes;
• Experience with solid modeling or CAD;
• Basic scripting or light programming skills (Python, Java, etc.).
