Charles W. Forsberg
Dr. Charles Forsberg is the Executive Director for the MIT Nuclear Fuel Cycle Study, Director and principle investigator for the MIT Fluoride Salt-Cooled High-Temperature Reactor Project, and the Idaho National Laboratory University Lead for Hybrid Energy Systems. Before joining MIT he was a Corporate Fellow at Oak Ridge National Laboratory (ORNL). He is a Fellow of the American Nuclear Society and the American Association for the Advancement of Science. Dr. Forsberg received the 2002 American Nuclear Society Special Award for Innovative Nuclear Reactors (Fluoride-salt-cooled high-temperature reactors), and in 2005 the American Institute of Chemical Engineers Robert E. Wilson Award in recognition of chemical engineering contributions to nuclear energy, including his work on reprocessing, waste management, repositories, and production of liquid fuels using nuclear energy. He holds 11 patents and has published more than 250 papers. He is a licensed professional engineer.
Nuclear fuel cycles, including disposal of wastes, are central to nuclear power. With the recent completion of the MIT Future of the Nuclear Fuel Cycle report, a series of critical questions were identified that are the basis of future research. One top-level question is how the fuel cycle should be organized (download pdf)—including whether backend fuel cycle facilities should be collocated at the repository to improve economics, repository performance, nonproliferation characteristics, and public acceptance. This question leads to a broad set of research questions that define our research interests.
The FHR is a new reactor concept developed within the last decade that combines four existing technologies (download pdf) in a new way that may create a more economic high-temperature reactor with higher levels of inherent safety. The four technologies are high-temperature graphite coated-particle fuel from gas-cooled reactors, liquid salt coolants from molten salt reactors, high-efficiency air Brayton power cycles that require no water cooling from gas turbines designed to burn natural gas, and safety systems from sodium-cooled fast reactors. Dr. Forsberg leads the Integrated Research Project to develop a pathway to commercial deployment—a project lead by MIT with the University of California at Berkeley and the University of Wisconsin at Madison as partners. It is a 3-year project supported by the U.S. Department of Energy.
Long term energy goals include (1) eliminating dependence on foreign oil and (2) low greenhouse gas emissions. The question is how to couple nuclear with other energy sources to meet these goals. Options for liquid fuels production include nuclear liquid biofuels and low-environmental impact nuclear shale oil production. The other challenge is integrating nuclear and renewable energy sources to meet variable electricity and other energy needs. This requires hybrid energy systems that enable capital intensive nuclear and renewable systems to operate at full capacity while meeting variable electricity demand (download pdf). It involves development of technologies (download pdf) such as nuclear-geothermal gigawatt-year energy storage, nuclear wind hydrogen systems, and nuclear shale-oil electricity systems. There remain major technical questions and challenges.
The Concentrated Solar Power on Demand system (CSPond) (download pdf) is a new type of high-efficiency solar power system with operating temperatures between 700 and 950°C. The high-temperature salt technology and power systems are similar or identical to those required for fluoride salt-cooled high-temperature reactors (more). Consequently this is a joint project between NSE and the Mechanical Engineering Department. It is part of a broader effort to develop high-temperature salt-cooled power systems download pdf.
