EEIP PhD Intern - Nuclear Sciences

Pacific Northwest National Laboratory•Richland, WA

4d•$24 - $36•Onsite

About The Position

At PNNL, our core capabilities are divided among major departments that we refer to as Directorates within the Lab, focused on a specific area of scientific research or other function, with its own leadership team and dedicated budget. Our Science & Technology directorates include National Security, Earth and Biological Sciences, Physical and Computational Sciences, and Energy and Environment. In addition, we have an Environmental Molecular Sciences Laboratory, a Department of Energy, Office of Science user facility housed on the PNNL campus. The Energy and Environment Directorate delivers science and technology solutions for the nation’s biggest energy and environmental challenges. Our more than 1,700 staff support the Department of Energy (DOE), delivering on key DOE mission areas including: modernizing our nation’s power grid to maintain a reliable, affordable, secure, and resilient electricity delivery infrastructure; research, development, validation, and effective utilization of renewable energy and efficiency technologies that improve the affordability, reliability, resiliency, and security of the American energy system; and resolving complex issues in nuclear science, energy, and environmental management. The Nuclear Sciences Division, part of the Energy and Environment Directorate, delivers science and technology innovations for the environment, energy, and national security. At a time when complex challenges are emerging on many fronts, we address some of the most challenging national and international nuclear issues. This includes providing technological solutions that protect the public health and safety around nuclear facilities, developing durable new materials for extreme nuclear environments, innovating new nuclear processes for the safety and security of the nation, and delivering new approaches for accelerating environmental cleanup of nuclear sites. Pacific Northwest National Laboratory (PNNL) is seeking PhD students passionate about creating a sustainable energy future through science and engineering to join us for a 10 week paid summer internship as part of the Energy and Environment Internship Program (EEIP). Within PNNL’s Nuclear Sciences Division, our scientists and engineers tackle some of the nation’s most complex challenges: advancing energy independence, remediating legacy nuclear waste, and strengthening national security. Our work blends experimentation, modeling, and engineering of nuclear materials and processes to deliver innovative solutions for the U.S. government and industry. Positions are based in Richland, WA. Work is primarily on-site, with remote arrangements considered only in rare circumstances and strictly based on business need.
