The Ken and Mary Alice Lindquist Department of Nuclear Engineering at Penn State is one of the top ranked nuclear engineering programs in the United States. The department distinguishes itself with a strong focus on experimental research. The actively growing department leads four educational programs for students pursuing a bachelor of science, a master of science, a master of engineering, or a doctoral degree. The Radiation Science and Engineering Center (RSEC) facilities, including the Breazeale Reactor, are available to nuclear engineering faculty and students at Penn State for research and instruction. RSEC houses the Breazeale Nuclear Reactor, the country’s first and longest operating licensed nuclear research reactor. Having access to an operating research reactor is a key strength for the department and enables Penn State to harness research and educational opportunities that are unique in the United States. See how we’re inspiring change and impacting tomorrow at nuce.psu.edu.
