Appendix I

Statement of Task for Parallel National Academies’ Study Laying the Foundation for New and Advanced Nuclear Reactors in the United States

The National Academies of Sciences, Engineering, and Medicine will appoint an ad hoc committee of experts to identify opportunities and barriers to the commercialization of new and advanced nuclear reactor technologies in the United States over the next 30 years as part of a decarbonization strategy. Specific topics the committee will examine include:

  • The research, development, and demonstration needed for new and advanced nuclear reactor technologies to reach commercial readiness, the potential for leveraging technological developments outside the nuclear energy sector, and the manufacturing, construction, financial, societal, and other barriers associated with their deployment;
  • The operational characteristics of these technologies, including their implications for safety, security, and nonproliferation, as well as their interaction with other low-carbon generation and storage resources that may be relevant to a changing electricity system;
  • The economic, regulatory, and business challenges associated with commercialization of these technologies;
  • The implications of these technologies for the front and back end of the fuel cycle;
  • The viability of these technologies in applications outside the electricity sector, for example in desalination, water and wastewater treatment, hydrogen production, or process heat;
  • The role of the U.S. Government in sponsoring the development and commercialization of new and advanced nuclear reactor technologies to provide clean energy, to address national-security and nonproliferation goals, or to assist in nuclear exports; and
  • The future workforce and educational needs to support the research, development, and deployment of these technologies.

The United States has deployed commercial nuclear power since the 1950s, and as of 2021, nuclear power accounts for approximately 20 percent of U.S. electricity generation. The current commercial nuclear fleet consists entirely of thermal-spectrum, light water reactors operating with low-enriched uranium dioxide fuel in a once-through fuel cycle. In recent years, the U.S. Congress, U.S. Department of Energy, and private sector have expressed considerable interest in developing and deploying advanced nuclear reactors to augment, and possibly replace, the U.S. operating fleet of reactors, nearly all of which will reach the end of their currently licensed operating lives by 2050. Much of this interest stems from the potential ability of advanced reactors and their associated fuel cycles - as claimed by their designers and developers - to provide a number of advantages, such as improvements in economic competitiveness, reductions in environmental impact via better natural resource utilization and/or lower waste generation, and enhancements in nuclear safety and proliferation resistance.

At the request of Congress, this report explores merits and viability of different nuclear fuel cycles, including fuel cycles that may use reprocessing, for both existing and advanced reactor technologies; and waste management (including transportation, storage, and disposal options) for advanced reactors, and in particular, the potential impact of advanced reactors and their fuel cycles on waste generation and disposal.
