Senior Nuclear Criticality Safety Engineer

The role

The Senior Nuclear Criticality Safety Engineer will perform criticality safety evaluations and develop the nuclear criticality safety basis. This role involves architecting the nuclear criticality safety program for a used nuclear fuel recycling facility.

What you will do

• Identifying and evaluating nuclear criticality safety (NCS) hazards for fuel cycle facilities
• Performing criticality safety evaluations (CSEs) to demonstrate subcriticality
• Developing the criticality code validation report
• Demonstrating compliance with the double-contingency principle
• Documenting criticality hazard analyses, CSEs, and supporting technical information
• Evaluating and implementing controlled parameters for the NCS program
• Developing the criticality accident alarm system and inadvertent criticality emergency response plan
• Supporting safety basis development and licensing efforts
• Developing and administering the NCS program, methodologies, and management measures

Required qualifications

• Bachelors, Masters, or PhD in nuclear engineering, chemical engineering, or chemistry, or related field
• Minimum 5+ years experience performing CSEs as a part of a nuclear facility’s safety basis
