Summer Internship in Nuclear Science and Security

For over 20 years, LLNL’s Glenn T. Seaborg Institute (GTSI) summer internship programs have offered graduate students the opportunity to engage in practical research experience to further their educational goals.

The goal of the program is to facilitate the training of next-generation scientists to solve critical national problems in the fields of nuclear science and security. For eight weeks, participating graduate and senior undergraduate students will have the opportunity to:

  • Carry out research under the supervision of a staff scientist
  • Attend a weekly lecture series
  • Interact with other students
  • Present their work in poster format at the end of the program
  • Meet federal sponsors from the Defense Threat Reduction Agency (DTRA), an agency that enables the Department of Defense and the U.S. government to ensure nuclear deterrence and to prepare for and combat weapons of mass destruction and improvised threats.
  • Dates

    June 15–August 7, 2020

  • Location

    LLNL, Livermore, CA—40 miles east of San Francisco.

  • Requirements
