This report summarizes the current progress of GA commercial HTGR application studies, with emphasis on three basic HTGR heat sources with 750/sup 0/C (1382/sup 0/F), 850/sup 0/C (1562/sup 0/F), and 950/sup 0/C (1742/sup 0/F) core outlet temperatures. These outlet temperatures then define the supporting technical systems and the potential process applications. Nuclear heat source designs for 1170-MW(t) and 2240-MW(t) HTGR-SC/C plants are described together with plant seismic model and component dynamic analyses, risk assessment, and the results of plant optimization studies. An initial survey of the potential of the HTGR-SETS, a concept that couples a conventional HTGR NHS to an external heat transport and sensible heat storage system, is discussed. Candidate applications are identified. Two process heat variants, an 850/sup 0/C (1562/sup 0/F) (indirect cycle) and a 950/sup 0/C (1742/sup 0/F) (direct cycle) 1170-MW(t) HTGR-PH plant, are defined. System design, plant dynamics and control, safety, and reliability evaluation of the two concepts are considered. The results of a review of process heat requirements to determine the suitability of the HTGR-PH for supplying high-temperature heat energy for hydrogen production, coal liquefaction, and other processes are presented.
