This summary report describes comparisons of High Temperature Gas-Cooled Reactor (HTGR) plants based on the monolithic and modular reactor concepts as sources of process steam. This report presents a series of economic case studies comparing total investment requirements and steam production costs. One of the prime objectives of the GFY 1982 HTGR development program was an economic comparison of the 2240 MWt monolithic HTGR with a modular HTGR reactor system (MRS) consisting of a number of small nuclear heat sources (NHSs) coupled in parallel. The power rating of the modules is 250 MWt in the case of the reformer concept and 300 MTt in the case of the steam cycle-cogeneration concept. Specifically, in this report the economics of monolithic and modular HTGR systems, designed for equivalent process steam availability and for production of the same quantity of process steam, are compared. The report includes monolithic vs modular comparisons for two applications of the HTGR.
