Criticality Safety Engineer

Job Description Summary

The Criticality Safety Engineer provides technical nuclear safety support of fuel manufacturing operations at the Global Nuclear Fuel (GNF) facility in Wilmington NC. In this role you will utilize knowledge of nuclear safety principles and engineering to analyze process operations and implement effective nuclear safety controls. You will work closely with engineering and operations staff to ensure the safe and compliant manufacturing of nuclear fuel. This is an entry level position that does not require prior work experience in Criticality Safety.

The Criticality Safety Engineer is responsible for evaluating credible criticality accident sequences, performing Monte Carlo code calculations, and documenting Nuclear Criticality Safety Evaluations (NCSE). This role also reviews and approves proposed facility changes, performs audits of operations and safety controls, participates on Integrated Safety Analysis (ISA) teams, and support criticality safety program improvements. The position will primarily support existing GNF nuclear fuel manufacturing operations at the Wilmington site; as well as advanced fuel manufacturing projects and satellite nuclear business units as needed.

• Document Nuclear Criticality Safety Evaluations (NCSEs) required to demonstrate safety for new or fuel manufacturing operations and modifications to existing facilities.
• Evaluate normal and credible abnormal conditions for facilities and operations.
• Establish criticality limits on controlled parameters, specify criticality control requirements and functionality, and perform neutronics calculations.
• Participate on ISA team meetings as a member of criticality safety to support development of the process hazard analysis and supporting risk assessments.
• Review and approve design changes and ensure the impacts to criticality safety are addressed.
• Review and approve facility documentation such as procedures, training, and functional test instructions to ensure criticality requirements are properly implemented.
• Support routine NRC inspections of the facility operations and the criticality safety program.

• BS or MS in Nuclear Engineering
• Experience using Monte Carlo methods such as KENO and MCNP.
• College coursework or training on Criticality Safety Principles.
• Work experience in Criticality Safety (e.g., internship, co-op, graduate research)
• Work experience in at a DOE or NRC regulated nuclear materials facility.
• Knowledge of hazard analysis and the double contingency principle.
• Ability to develop creative solutions for complex, challenging issues.
