Pacific Northwest National Laboratory
Richland, WA Intern
POSTED ON 10/2/2025

Overview

Protecting U.S. residents and visitors is among our nation’s highest priorities. As adversaries gain access to sophisticated technologies and materials, the threats grow more dynamic and complex—from cyber and nuclear to chemical and biological weapons of mass effect and other forms of terrorism. The PNNL national security mission employs our researchers, tools, and technologies to play a key role in advancing the ability to identify and secure nuclear materials, detect weapons of mass effect, manage nonproliferation treaties, secure our nation's borders, and protect critical infrastructures. PNNL’s scientific discovery and capabilities—rooted in innovative theory, methods, algorithms, and tools—are enabling stronger, more resilient technologies and systems to safeguard national security. Coupled with decades of radiological and nuclear materials expertise, advanced computing and threat analysis capabilities, and a broad fundamental science base, we are identifying and countering emerging threats that have significant impact at home and around the globe.

The Nuclear Engineering group at Pacific Northwest National Laboratory is searching for a Graduate Technical Intern to join a team of multidisciplinary scientists and engineers to assist in the research and development supporting advanced nuclear radioisotope power systems. This position will assist with the creation and implementation of innovative techniques to overcome design, fabrication, testing, and deployment challenges with novel radioisotope power systems.

 

The successful candidate will be responsible for supporting the development of space nuclear engineering capability at PNNL and will have the opportunity to broaden the laboratory experiences as interest and project availability provide.
