This report describes the application of a high-temperature gas-cooled reactor (HTGR) that operates in a steam cycle/cogeneration (SC/C) mode to supply process heat and electricity for the recovery of oil from shale using a modified Paraho process. The technical and preliminary economic merits of an 1170-MW(t) HTGR-SC/C plant are assessed along with those of very high temperature (850/sup 0/C (1562/sup 0/F)) process heat reactor and the standard fossil fuel-fired heat source for this application. The energy requirements for the modified Paraho process were developed utilizing design parameters from the Davy McKee study which considered the HTGR-PH and conventional Paraho process (indirect gas retorting) using fossil fuel. A heat balance/steam cycle diagram shows the integration of an 1170-MW(t) HTGR-SC/C plant with the process and the cogeneration of 275 MW(e) electric power. A preliminary cost estimate shows a price of $43.29 (1980 $, 30-y levelized) per barrel of upgraded shale oil for a 1995 plant startup of an 1170-MW(t) HTGR-SC/C plant and $41.90 (1980 $, 30-y levelized) per barrel with an 1170-MW(t) HTGR-PH plant. The reference fossil-fueled process shows a cost of $50.03 (1980 $, 30-y levelized) per barrel using a consistent set of economic ground rules with fuel valued at market price. The HTGR-SC/C plant appears technically and almost economically favorable. Environmental and pollution impacts are also assessed. 7 figures, 9 tables.
