A total energy system (TES) is designed to supply the thermal and electrical energy requirements of Fort Know, Kentucky for a period of 30 years, with startup scheduled for early 1985. Considered for use as the central station power plant for this system are a combined coal gasification, fossil-fired gas turbine (CGGT) power plant and a direct Brayton cycle high-temperature gas-cooled reactor, helium gas turbine (HTGR/GT) power plant. Several utility system configurations affording different thermal/electrical energy demand ratios are studied for each supply option. With the primary system optimization criterion being the choice of the TES providing a minimum of total energy costs over the system lifetime, it is found that the optimal thermal-electrical load split for each supply option occurs at approximately 80 % of the base's total energy demands supplied thermally. Within the limits of the unit-cost assumptions made and for the range of cases studied, it is found that the present-worth total cost of the optimized HTGR/GT system in 1985 dollars) is Dollar 234.5 million and the corresponding optimal system cost for the fossil CGGT alternative is Dollar 182.2 million.
