About the job
Thank you for considering a career with Oklo! We are excited to announce an opening for a Senior Nuclear Criticality Safety Engineer to become a vital part of our innovative team.
Position Overview
As a Senior Nuclear Criticality Safety Engineer at Oklo, your primary responsibility will be to conduct thorough criticality safety evaluations, establish a robust nuclear criticality safety basis, and design the nuclear criticality safety program for our groundbreaking used nuclear fuel recycling facility.
Key Responsibilities:
- Assess and analyze nuclear criticality safety (NCS) hazards within fuel cycle facilities.
- Execute criticality safety evaluations (CSEs) to confirm subcriticality during both normal and potential abnormal scenarios.
- Prepare the criticality code validation report.
- Ensure compliance with the double-contingency principle.
- Document criticality hazard analyses, CSEs, and associated technical data.
- Review and implement controlled parameters for the NCS program.
- Develop the criticality accident alarm system and the inadvertent criticality emergency response plan.
- Assist in the development of safety bases and licensing initiatives.
- Oversee the NCS program, methodologies, and management practices.
Minimum Qualifications:
- Bachelor's, Master's, or PhD in nuclear engineering, chemical engineering, chemistry, or a closely related field.
- A minimum of 5 years of experience conducting CSEs as part of the safety basis of a nuclear facility.
Preferred Qualifications:
- Familiarity with used nuclear fuel recycling technologies.
- Over 10 years of experience performing criticality safety evaluations for an NRC-licensed fuel cycle facility.
Desired Competencies:
We seek a Senior Nuclear Criticality Safety Engineer who exemplifies:
- In-depth knowledge of nuclear science, physics of criticality, and chemistry.
- Understanding of nuclear fuel cycle processes and potential facility accident scenarios.
- Proficiency in using Attila4MC, MCNP, SCALE, and/or Serpent codes and modules.
- Familiarity with critical experiments and their objectives.
- Expertise in criticality-specific codes, standards, regulatory requirements, and industry practices related to nuclear fuel cycle facilities.
- Awareness of NUREG-1513, NUREG-1520, NUREG/CR-6410, NUREG/CR-6698, NUREG/CR-7311, and NRC RG guidelines.
