Oklo is seeking a Senior Nuclear Criticality Safety Engineer to join its team developing advanced fission power plants, nuclear fuel recycling technologies, and critical radioisotope supply chains. This is a hybrid role based in Santa Clara, CA, with the option to work remotely with required travel to headquarters twice quarterly and mandatory in-person onboarding for the first two weeks.
In this role, you will be 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. You will identify and evaluate nuclear criticality safety hazards for fuel cycle facilities, perform criticality safety evaluations (CSEs) to demonstrate subcriticality under normal and credible abnormal conditions, and develop criticality code validation reports. Additional responsibilities include demonstrating compliance with the double-contingency principle, documenting criticality hazard analyses 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, and developing and administering the NCS program, methodologies, and management measures.
Oklo is a venture-backed advanced fission company that was the first to receive a site use permit from the U.S. Department of Energy for a commercial advanced fission plant, was awarded fuel material from Idaho National Laboratory, and submitted the first custom combined license application for an advanced reactor to the U.S. Nuclear Regulatory Commission. The company is also developing advanced fuel recycling technologies in collaboration with the U.S. Department of Energy and U.S. National Laboratories.
The ideal candidate is a startup-oriented person who thrives in fast-paced, iterative environments, is self-motivated and passionate about clean energy, works effectively as a team player, communicates clearly and technically, and is detail-oriented with excellent writing skills. You should be comfortable with ambiguity, creative problem-solving, and thinking differently about nuclear safety challenges.
REQUIREMENTS:
- Bachelor's, Master's, or PhD in nuclear engineering, chemical engineering, chemistry, or related field
- Minimum 5+ years of experience performing criticality safety evaluations (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
- Proficiency 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
- Knowledge of structural design, analysis, and construction
BONUS QUALIFICATIONS:
- Knowledge of used nuclear fuel recycling technologies
- 10+ years of experience performing criticality safety evaluations for an NRC licensed fuel cycle facility
