[en] The U.S. Department of Energy (DOE) Modular High-Temperature Gas-Cooled Reactor (MHTGR) program has produced a conceptual design which has been reviewed by the U.S. Nuclear Regulatory Commission (NRC). The results of the review were generally favorable, and the program team has now moved into the preliminary design phase. The program team consists of a nuclear island engineering (NIE) team, an energy conversion area (ECA) team, a design integration organization, and a technology development team. Utility user requirements are provided by a utility organization which also participates in design and programmatic review/evaluations. This paper will review the direction and accomplishments of each participating organization. (author)
