Abstract: The Modular High-Temperature Gas-Cooled Reactor (MHTGR) is an advanced reactor concept being developed under a cooperative program involving the U.S. Government, the utilities, and the nuclear industry. This plant design utilizes basic high-temperature gas-cooled reactor (HTGR) features of ceramic fuel, helium coolant, and a graphite moderator. The MHTGR design approach leading to exceptional safety performance also leads to plant operation which is characterized by extremely low radiological emissions even for very low probability accidents. Coated fuel particles retain radionuclides within the fuel, thus minimizing material contamination in personnel exposure. The objective of this paper is to characterize radioactive effluents expected from the normal operation of an HTGR. In addition, other nonradioactive effluents associated with a power generating facility are discussed.
