Costs of electricity and thermal energy 380 F hot water produced by nuclear and fossil-fired power plants in the 100 Mwe size range for 1985 start-up have been estimated in 1985 dollars, levelized over plant life. While the PWRRankine system was estimated to produce electricity as a sole product cheaper than an HTGRBrayton plant 30.3 versus 41.5 millsKwhr the HTGR unit was shown to produce Total Energy products more economically than the PWR 25.2 millsKwhn and 2.58 MBTU versus 30.3 and 2.93. Breakeven fuel costs for comparable fossil-fired steam-electric power plants were found to be about 16 ton for coal and 9 bbl for oil approximately 10 ton and 6 bbl in 1974 dollars oil-fired gas turbine units were found to have breakeven costs of 18 bbl approximately 10.6 bbl in 1974 dollars. Parametric and sensitivity studies were also carried out to examine the affects of size 50-200Mwe, annual cost of money 8 - 12, plant lifetime 20-40 years and plant start-up date 1980-1990. It is concluded that the HTGRBrayton plant is superior to the other nuclear and fossilRankine options for Total Energy applications. The fossil-fired gas turbinetotal energy system is identified as a strong competitor for the proposed application, and is potentially superior to the HTGR if fossil fuel prices do not escalate prohibitively.
