Job Description
This role is responsible for providing technical capabilities in Nuclear Criticality Safety (NCS) to ensure TRISO-X Fuel Fabrication Facility fissile materials are processed, stored, and handled safely to prevent an inadvertent nuclear criticality, and personnel and the public/environment are protected in accordance with Nuclear Regulatory Commission (NRC) requirements in 10 CFR 70. This role will transition from design/licensing support through start-up/commissioning to supporting day-to-day facility operations.
Job Profile Tasks/Responsibilities
- Define the safety basis for fissile material operations by evaluating and analyzing equipment, processes, and procedures; implement and facilitate NCS programs and procedures; and monitor the effectiveness of NCS items relied on for safety (IROFS), limits, controls, and barriers.
- Develop/review/revise NCS evaluations to demonstrate subcriticality for normal operations and process upsets of TRISO-X fuel fabrication processes and TRISO-X Facility operations, including processes involved in producing TRISO fuel forms, quality control activities, recycling/recovery of process materials, managing effluents and waste materials, and conducting maintenance activities.
- Develop/review/revise calculations by executing NCS computer codes and models to support NCS evaluations.
- Participate in and/or facilitate Process Hazards Analysis activities with multidiscipline teams to identify potential criticality, radiological, chemical, and fire/explosion hazards to support the Integrated Safety Analysis (ISA) process.
- Evaluate accident sequences to determine limits and controls necessary to demonstrate double contingency and perform ISA risk assessment to identify IROFS to ensure a criticality is highly unlikely.
- Consult with and advise operations, maintenance, and engineering personnel on the NCS impacts of new or proposed changes to processes, procedures, and facility designs/modifications.
- Participate in design reviews.
- Conduct surveillances, inspections, walk-downs, investigations, and audits/assessments of fissile material operations, and unusual incidents to ensure compliance with approved procedures and safety bases.
- Develop/revise/deliver NCS training to operations, maintenance, and other personnel.
- Develop/revise NCS postings and operator aids to implement administrative controls to ensure they are unambiguous, easily understood, and readily achievable.
- Provide support to the emergency response team.
- Maintain professional demeanor and behavior at all times in all forms of communication.
- Perform other duties as assigned by manager.
- Level II: Support team members with the execution of the core tasks and responsibilities listed in the Job Profile Task/Responsibilities section of this document
- Level III: Execute the core tasks and responsibilities listed in the Job Profile Task/Responsibilities section of this document.
- Level IV: Lead the execution of the core tasks and responsibilities listed in the Job Profile Task/Responsibilities section of this document.
- Provide feedback and guidance to more junior team members with the execution of the core tasks and responsibilities listed in the Job Profile Task/Responsibilities section of this document.
Job Profile Minimum Qualifications
- Bachelor's degree in any STEM related field from an ABET-accredited college or university.
- Level II: Typically, three plus years of experience in the nuclear criticality safety field with preparing, reviewing, and/or revising safety basis evaluations that identify and document NCS limits and controls.
- Experience using SCALE, MCNP, or other NCS computer codes and models to demonstrate subcriticality.
- Ability to become qualified under a formal training and qualification program consistent with guidelines presented in ANSI/ANS-8.26-2007, Criticality Safety Engineer Training and Qualification Program.
- Level III: Typically, five plus years of experience in the nuclear criticality safety field with preparing, reviewing, and/or revising safety basis evaluations that identify and document NCS limits and controls.
- Experience using SCALE, MCNP, or other NCS computer codes and models to demonstrate subcriticality.
- Ability to become qualified under a formal training and qualification program consistent with guidelines presented in ANSI/ANS-8.26-2007, Criticality Safety Engineer Training and Qualification Program.
- Working knowledge of relevant industry codes and standards for nuclear criticality safety in non-reactor facilities and operations. Understanding and experience applying regulatory requirements, standards, and guidance.
- Level IV: Typically, ten plus years of experience in the nuclear criticality safety field with preparing, reviewing, and/or revising safety basis evaluations that identify and document NCS limits and controls.Three years may be credited towards years of experience when successfully performing the following duties: Preparing and Reviewing ISA Risk Assessments, Leading Process Hazards Analysis, and Preparing ISA Summary documentation.
