About this role

Senior Nuclear Criticality Safety Engineer responsible for performing criticality safety evaluations, developing the nuclear criticality safety basis, and architecting the nuclear criticality safety program for a first-of-a-kind used nuclear fuel recycling facility.

Responsibilities

—Identify and evaluate nuclear criticality safety (NCS) hazards for fuel cycle facilities
—Perform criticality safety evaluations (CSEs) to demonstrate subcriticality under normal and credible abnormal conditions
—Develop the criticality code validation report
—Demonstrate compliance with the double-contingency principle
—Document criticality hazard analyses, CSEs, and supporting technical information
—Evaluate and implement controlled parameters for the NCS program
—Develop the criticality accident alarm system and inadvertent criticality emergency response plan
—Support safety basis development and licensing efforts
—Develop and administer the NCS program, methodologies, and management measures

Qualifications

—Minimum 5+ years experience performing CSEs as part of a nuclear facility's safety basis
—Knowledge of nuclear science, physics of criticality, and chemistry
—Knowledge of nuclear fuel cycle processes and nuclear fuel cycle facility accident scenarios
—Proficient with Attila4MC, MCNP, SCALE, and/or Serpent codes and modules
—Familiarity with critical experiments and their purpose
—Knowledge of criticality-specific codes, standards, regulatory requirements, and industry practices for nuclear fuel cycle facilities
—Familiarity with NUREG-1513, NUREG-1520, NUREG/CR-6410, NUREG/CR-6698, NUREG/CR-7311, and NRC RG 3.71

Desired

—Knowledge of used nuclear fuel recycling technologies
—10+ years of experience performing criticality safety evaluations for an NRC licensed fuel cycle facility
—Knowledge of structural design, analysis, and construction
