About

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 from other programs with a strong focus on experimental research in power, science, security and safety. 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 department also houses the Breazeale Nuclear Reactor, the country’s first and longest operating licensed nuclear reactor. The construction and operation of the reactor introduced nuclear engineering to Penn State, and, in doing so, harnessed research and educational opportunities as key strengths for the department. See how we’re inspiring change and impacting tomorrow at nuce.psu.edu.
