Status of HTGR steam cycle/cogeneration lead plant design

The conceptual design of a High Temperature Gas-Cooled Reactor (HTGR) Steam Cycle/Cogeneration (SC/C) Lead Plant has been completed and is described in this paper. It is a 2240-MW(t) variable cogeneration plant that generates up to 5 x 10/sup 6/ lb/h (630 kg/s) of high-temperature process steam and 230 MW(e) of cogenerated electricity or, alternatively, 820 MW(e) of electric power. The plant requirements and resulting design have been developed by use of functional analysis based on the Integrated Approach. Top-level goals for performance, availability, and economics have been specified, as well as goals for investment protection and public safety.
