The Applied Nuclear Technologies department is seeking a motivated Year-Round R&D Graduate Intern to join our Critical Experiments Team. The successful candidate will assist in the design of experiments to support safe and efficient fissionable material operations. These integral criticality benchmark-quality experiments provide the Nuclear Critically Safety (NCS) community the ability to resolve biases associated with the computational tools used for evaluating criticality safety.
On any given day, you may be called on to:
Apply existing knowledge and gain new knowledge towards designing, performing, and documenting critical benchmark experiments
Perform neutron transport modeling and data analysis
Conduct research and publish
Demonstrate the ability to work effectively and responsibly in a research team, and contribute towards a safe and secure working environment
Due to the nature of the work, the selected applicant must be able to work onsite.
Salary Range:At Sandia, we value the important work done by our interns and its contribution to National Security. Because of this, our interns earn competitive pay rates. Our pay structure is based on earned credit hours, classification, and degree level. Your pay rate will be determined during the hire process and included in your offer package. You can view the Intern Pay Rate chart here (https://(Use the "Apply for this Job" box below).)

You bring the confidence and skills to be eligible for the job by meeting these minimum requirements:
Earned bachelor's degree
Currently attending and enrolled full time in an accredited science, engineering, or math graduate program
Minimum cumulative GPA of 3.0/4.0
Ability to work up to 30 hours per week during the academic year, and up to 40 hours per week during the summer
Ability to secure and maintatin a U.S. security clearance which requires U.S. citizenship
Qualifications We Desire:Enrolled in a Nuclear Engineering, Mechanical Engineering or Physics program
Basic understanding of Nuclear Criticality Safety (NCS) principles and practices
Experience in MCNP or SCALE code packages
Basic understanding of sensitivity and uncertainty techniques for use in NCS
Knowledge in programming for automation, optimization, and analysis
Ability to work in a team environment and independently to solve challenging problems
Strong verbal and written communication skills
Posting Duration:This posting will be open for application submissions for a minimum of three (3) calendar days, including the 'posting date'. Sandia reserves the right to extend the posting date at any time.
About Our Team:As a part of the Radiation & Electrical Sciences Center, the Applied Nuclear Technologies Department (org. 1314) explores, develops, and applies physics and engineering principles to many areas of nuclear and electrical engineering. The Department is responsible for the Device Physics, Energetic Neutrons, and Transient Neutrons portion of the Sandia
¿ s Weapon Survivability (WS) Program. Our group conducts high fidelity radiation effects experiments on semiconductor devices and materials at facilities such as the Annular Core Research Reactor, the National Ignition Facility, and the Laboratory for Laser Energetics in support of national security missions. We collaborate with the Nuclear Facilities Operations and the Radiation Modeling and Metrology departments at Sandia to
1) tailor and characterize appropriate testing environments in the TA-V nuclear facilities to meet customer needs and
2) design and conduct nuclear criticality experiments in the Sandia Critical Experiments (SCX) Facility for the NNSA DOE Nuclear Criticality Safety Program (NCSP) and developed and deliver Hands-on training with critical experiments for the NCSP. This team is part of the Radiation, Electrical and High Energy Density Science (REHEDS) Research Foundation at Sandia.
