Costs have been estimated to design, construct, operate and maintain Modular High Temperature Gas-Cooled Reactor (MHTGR) power plants. The cost estimates are based upon the conceptual design of the reference MHTGR plant for which a summary description is provided in the MHTGR Conceptual Design Summary Report. The reference MHTGR plant consists of four 350 MW(t) reactor modules and two turbine generators (4 x 2) which produce a net output of approximately 540 MWe. The reactor modules and all other equipment and facilities necessary for the control of radionuclides are contained on a Nuclear Island (NI). All other plant facilities are part of the Energy Conversion Area (ECA) which is physically separated from the NI. Costs for reference MHTGR plants were developed for the following four cases: a Lead plant consisting of the first commercial plant conforming to the reference 4 x 2 plant design including the licensing-related costs from Final Design Approval (FDA) through to completion of the design certification process, approximate costs were also developed for the design licensing and technology development necessary to obtain the FDA; a Replica plant conforming to the certified design that follows the first commercial plant; a Target plant which is the Nth-Of-A-Kind (NOAK) equilibrium plant conforming to the certified design; and a large Target plant consisting of two power blocks with each power block conforming to the certified design.
