This report was prepared in response to a request from Acting Assistant Secretary for Nuclear Energy, John Kotek. In a letter dated July 29, 2016, he directed the Nuclear Energy Advisory Committee (NEAC) Chairs to form a team, comprised of members from NEAC subcommittees, "to assess the need and determine the requirements for an irradiation test reactor which would augment existing domestic capabilities to support the development and deployment of advanced non-light water reactors as well as to accommodate the future needs of light water reactor technologies.”
