Nuclear Security Enterprise Day

September 12, 2023 @ 9:00 am - 3:00 pm

Come Meet Your Future Employer!

It all starts with a conversation, and we invite students to attend the 2023 Nuclear Security Enterprise Day on campus in College Station at the Zachry Engineering Education Complex located at 125 Spence St, College Station, TX 77843. The event will be held in the Chevron Conference Rooms on the 2nd Floor.


The Nuclear Security Enterprise (NSE) is made up of the National Nuclear Security Administration (NNSA) and its 8 labs, plants, and sites. NNSA is responsible for enhancing national security through the military application of nuclear science, which encompasses a vast variety of disciplines related to engineering and science.

If you are curious about what a career in national security might entail, or if you have always dreamed of serving our country through scientific development and application please register for this event. You will have the opportunity to speak face-to-face with researchers and recruiters from each NSE partner and learn about opportunities currently open.
