Research Interests:

As an INL employee for over 20 years, Steven Herrmann has gained experience in research, design, development, and demonstration of processes and equipment. He also has managed projects and personnel in the treatment of various materials of interest for the U.S. Department of Energy (DOE), including spent nuclear fuel and associated high-level, transuranic, and low-level wastes. These activities have primarily involved pyrochemical and electrochemical techniques and processes to separate and recover actinides from spent nuclear fuel, while directing fission and activation products into appropriate waste forms for disposal. Steven is currently leading a demonstration of an integrated kg-scale pyroprocess at INL for used nuclear fuel as part of a Joint Fuel Cycle Studies program – a 10-yr Cooperative Research and Development Agreement between multiple DOE national laboratories, the Republic of Korea, and the International Atomic Energy Agency.
