Neutronics Jobs in Pennsylvania (NOW HIRING)

Neutronics information

What is neutronics?

Neutronics is the study of the behavior and movement of neutrons within nuclear reactors or other systems where nuclear reactions occur. It involves analyzing how neutrons interact with materials, how they are absorbed or scattered, and how their distribution affects the operation and safety of a nuclear reactor. Neutronics specialists use mathematical models and simulations to optimize reactor design, ensure efficient fuel usage, and maintain safety standards. This field is essential for the effective and safe generation of nuclear energy.

What are the key skills and qualifications needed to thrive as a neutronics engineer, and why are they important?

To thrive as a Neutronics Engineer, you need a solid background in nuclear engineering, physics, and mathematics, typically supported by a relevant degree. Familiarity with reactor physics codes (such as MCNP or SCALE), simulation software, and sometimes a Professional Engineer (PE) license are often required. Analytical thinking, problem-solving abilities, and clear communication are crucial soft skills for effectively interpreting complex data and collaborating with multidisciplinary teams. These skills ensure the safe, efficient, and accurate modeling of nuclear systems, which is essential for reactor design, operation, and regulatory compliance.

What are some common challenges faced by professionals working in neutronics, and how can they be addressed?

Professionals in neutronics often encounter challenges such as accurately modeling complex nuclear systems, managing large datasets, and ensuring strict adherence to safety protocols. These challenges can be addressed by staying updated with the latest simulation tools, collaborating closely with multidisciplinary teams (such as nuclear engineers and safety analysts), and participating in ongoing training. Additionally, effective communication and documentation are essential for ensuring that results are clearly understood and can be acted upon by both technical and non-technical stakeholders.

What is the difference between Neutronics vs Radiation Protection Specialist?

AspectNeutronicsRadiation Protection Specialist
Required CredentialsDegree in nuclear engineering, certifications like NEUP or NEETDegree in health physics, certifications like CHP or RC
Work EnvironmentResearch labs, nuclear power plants, simulation centersField sites, hospitals, nuclear facilities
Industry UsageDesigning reactor cores, neutron transport analysisMonitoring radiation exposure, safety compliance

Neutronics focuses on neutron behavior and reactor design, while Radiation Protection Specialists concentrate on safety and exposure management. Both roles require nuclear-related credentials and often work within the nuclear industry, but their daily tasks and focus areas differ significantly.

Job description

Working at the Naval Nuclear Laboratory we foster pride in belonging to an organization whose culture is made up of these core values: Trust, Empowerment, and Collaboration. Our company promotes a positive culture while ensuring the safety and reliability of our nation's naval nuclear reactors, and training the Sailors who operate those reactors in the U.S. Navy's submarines and aircraft carrier Fleets. Looking for a lifetime career? Apply today! Job Description The Future Development Programs (FDP) department at the Naval Nuclear Laboratory (NNL) is seeking a highly motivated entry-level nuclear engineer to contribute to next generation reactor core design. FDP is currently leading the conceptual development of a new reactor core for the Navy's fast attack submarine fleet. Additional focus areas include defining future design spaces, evaluating innovative technologies, and assessing cost-performance trade-offs for advanced submarine propulsion concepts. In this role, you will apply your nuclear engineering education to evaluate neutronic behavior, thermal performance, shielding design, or overall primary plant performance. You will help assess how new design concepts can improve the performance, safety, and capability of future naval reactors. Successful candidates will demonstrate a strong desire to develop a broad understanding of how multiple engineering disciplines integrate into reactor core design. FDP is currently in the conceptual core design phase, where close collaboration between nuclear design, thermal analysis, shielding, and reactor performance groups is essential. This phase will transition into detailed core and plant design, requiring development of sophisticated analysis models and execution of comprehensive evaluations to ensure maximum capability while ensuring the reactor is safe for deployment. This position requires strong communication skills and frequent interaction with multidisciplinary partners, including core manufacturing groups, materials performance groups, and reactor plant design organizations. Interested applicants must excel at working in a highly collaborative environment. Required Combination of Knowledge and Skill Bachelors degree from an accredited college or university in Nuclear Engineering or Physics; or Masters degree from an accredited college or university in Nuclear Engineering or Physics. Preferred Skills Cumulative GPA 3.2 or higher Coursework in thermal and nuclear design and analysis including neutronics, radiation transport, heat transfer, fluid mechanics, or finite element analysis Experience in engineering analysis, including the use of coding to post-process results in MATLAB or Python Strong written and verbal communication skills with an ability to articulate technical ideas in a clear and concise manner Compensation and Benefits Health, Dental, Vision & Voluntary Benefits Disability, Life & Accident Insurance 401(k) Savings program & Capital Accumulation Plan Personal & Medical Time Off Paid Parental Leave Flexible Work Schedules Tuition Assistance for Eligible Employees Student Debt Benefit Personal Time Off Sell Program Employee Assistance Program (EAP) Wellness Program Visit us online to view all NNL benefits! Pay Range $63,900.00 - $97,800.00 annually Salary information provided is a general guideline only. Annual salary is based upon candidate experience and qualifications, as well as market and business considerations. The Naval Nuclear Laboratory is operated for the U.S. Department of Energy (DOE) by Fluor Marine Propulsion, LLC (FMP), a wholly owned subsidiary of Fluor Corporation. Naval Nuclear Laboratory personnel are FMP employees who work at four DOE facilities: Bettis Atomic Power Laboratory, Knolls Atomic Power Laboratory, Kenneth A. Kesselring Site, and Naval Reactors Facility, and at the U.S. Department of Defense-owned Nuclear Power Training Unit-Charleston. FMP employees also have an established presence at numerous shipyards and vendor locations. For nearly 70 years, the Naval Nuclear Laboratory has developed advanced nuclear propulsion technology, provided technical support, and trained world-class nuclear operators to ensure the safe and reliable operation of our nation's submarine and aircraft carrier Fleets. The Naval Nuclear Laboratory is a national asset solely dedicated to the Naval Nuclear Propulsion Program. We rely on the dedication and innovation of our nearly 8000 engineers, scientists, technicians, and support personnel. All candidates must be U.S. citizens.
