What does a Nuclear Criticality Safety Engineer do?

A Nuclear Criticality Safety Engineer is responsible for ensuring that nuclear materials are handled, stored, and processed in a manner that prevents unintended nuclear chain reactions, known as criticality accidents. They analyze facility designs, operating procedures, and accident scenarios to assess risks and implement safety controls. Their work involves developing safety evaluations, performing calculations, and providing guidance on safe practices. This role is crucial in nuclear power plants, research labs, and facilities that handle fissile materials to protect workers, the public, and the environment.

What does a Nuclear Criticality Safety Engineer do?

As a nuclear criticality safety engineer, your responsibilities include conducting research and evaluating methods of transportation, handling, and storage of nuclear fuel to prevent an accident such as a nuclear reaction. You study and review research on nuclear fuel characteristics and calculation documents, as well as conduct an analysis of fuel transfer and storage plans provided by nuclear plants. Other duties include identifying potential hazards and areas in a nuclear plant that may be violating regulations, designing new methods for transport or storage, preparing proposal reports describing your recommendations, and submitting these reports to the government review board.

How does a Nuclear Criticality Safety Engineer typically collaborate with other professionals on-site?

Nuclear Criticality Safety Engineers work closely with a multidisciplinary team, including reactor operators, health physicists, process engineers, and regulatory compliance staff. They participate in safety reviews, provide technical guidance during facility modifications, and help develop and implement criticality safety procedures. Regular communication and teamwork are essential, as these engineers must ensure all stakeholders understand and follow safety protocols to prevent criticality accidents. Collaboration often includes attending interdepartmental meetings, conducting training sessions, and performing joint facility walkthroughs.

What are the key skills and qualifications needed to thrive as a Nuclear Criticality Safety Engineer, and why are they important?

To thrive as a Nuclear Criticality Safety Engineer, you need a strong background in nuclear engineering, physics, or a related field, often supported by a relevant bachelor's or master's degree. Familiarity with criticality safety codes (such as SCALE or MCNP), regulatory compliance standards, and radiation monitoring systems is essential. Attention to detail, strong problem-solving abilities, and effective communication skills are crucial for risk assessment and collaboration with multidisciplinary teams. These skills ensure the safe handling and processing of nuclear materials, preventing criticality accidents and ensuring regulatory compliance.

What is the difference between Nuclear Criticality Safety Engineer vs Nuclear Safety Engineer?

AspectNuclear Criticality Safety EngineerNuclear Safety Engineer
CertificationsOften requires certifications like ANSI/ANS-8 or equivalentMay require general nuclear safety or engineering certifications
Work EnvironmentFocuses on criticality safety in nuclear facilities and operationsEncompasses broader nuclear safety aspects including radiation protection and accident prevention
Industry UsagePrimarily in nuclear fuel handling, processing, and reactor operationsAcross nuclear power plants, research reactors, and regulatory agencies

The Nuclear Criticality Safety Engineer specializes in preventing nuclear chain reactions in fissile materials, ensuring safe handling and storage. In contrast, the Nuclear Safety Engineer has a broader role, addressing overall safety protocols, radiation protection, and accident prevention in nuclear facilities. While both roles require a strong understanding of nuclear principles, the Criticality Safety Engineer focuses specifically on criticality risks, making their expertise more specialized within the nuclear safety field.

Job description


SAIC is seeking a System Safety Engineer to provide critical safety engineering analysis and support for the Submarine Launched Cruise Missile - Nuclear (SLCM-N) development program. This advanced role involves integrating safety principles across the entire Department of Defense (DoD) acquisition lifecycle while adhering to MIL-STD-882E guidelines. The selected candidate will contribute to the design, development, and deployment phases of this next-generation weapons system, focusing on subsystem or whole-system safety, as required.
This role requires close collaboration with multidisciplinary teams consisting of engineers, program managers, and government stakeholders while also maintaining oversight of vendor activities. The candidate will work in a high-priority national defense environment, enabling safe and effective execution of a program critical to U.S. defense capabilities.
Note: The position supports remote, onsite, or hybrid work at NSWC Crane Division or DC Washington Naval Yard.
JOB RESPONSIBILITIES:
System Safety Engineering Support:
  • Conduct safety engineering analyses, including but not limited to Preliminary Hazard Analyses (PHAs), System Hazard Analyses (SHAs), and Software Hazard Analyses (SOHAs).
  • Perform hazard identification, risk assessments, and mitigation planning to ensure compliance with MIL-STD-882E.
  • Develop safety requirements for subsystems such as mechanical components, software systems, and electrical designs.
  • Provide oversight and guidance for safety-related tasks performed by vendors and subcontractors to ensure alignment with program goals.

Lifecycle Safety Integration:
  • Integrate safety considerations across all stages of the DoD acquisition lifecycle: concept development, system design, production, testing, fielding, and sustainment.
  • Collaborate with design teams to ensure safety requirements are fully addressed during system architecture development.
  • Apply industry best practices such as Model-Based Systems Engineering (MBSE) using tools like CAMEO and/or requirements management tools like DOORS.

Documentation and Reporting:
  • Prepare and maintain documentation of hazard analyses, risk assessments, and safety test results for program-level reviews.
  • Deliver comprehensive safety engineering reports and presentations to internal stakeholders and DoD leadership.
  • Create technical documentation for weapon systems safety certification and approval.

Program Support and Compliance:
  • Support program safety reviews, audits, and field evaluations to assess compliance with applicable standards.
  • Collaborate with acquisition teams to ensure adherence to DoD policy on lifecycle safety.
  • Provide recommendations for programmatic improvements to enhance operational safety and efficiency.

Qualifications
REQUIRED EDUCATION:
  • Bachelor's degree (minimum) in engineering, physics, or mathematics. Relevant disciplines include:
    • Systems Engineering (preferred for lifecycle safety integration).
    • Mechanical/Aerospace Engineering (preferred for vehicle/system component safety).
    • Electrical/Computer Engineering (preferred for control systems and radar designs).
    • Software Engineering (preferred for safety-critical software and autonomy systems).
    • Industrial Engineering (preferred for process/risk management).

REQUIRED EXPERIENCE/SKILLS:
