1170-MW(t) HTGR-PS/C plant application study report: SRC-II process application

Description: The solvent refined coal (SRC-II) process is an advanced process being developed by Gulf Mineral Resources Ltd. (a Gulf Oil Corporation subsidiary) to produce a clean, non-polluting liquid fuel from high-sulfur bituminous coals. The SRC-II commercial plant will process about 24,300 tonnes (26,800 tons) of feed coal per stream day, producing primarily fuel oil plus secondary fuel gases. This summary report describes the integration of a high-temperature gas-cooled reactor operating in a process steam/cogeneration mode (HTGR-PS/C) to provide the energy requirements for the SRC-II process. The HTGR-PS/C plant was developed by General Atomic Company (GA) specifically for industries which require energy in the form of both steam and electricity. General Atomic has developed an 1170-MW(t) HTGR-PS/C design which is particularly well suited to industrial applications and is expected to have excellent cost benefits over other sources of energy.

Assessment of very high-temperature reactors in process applications. Appendix II. VHTR process heat application studies

Description: A critical review is presented of the technology and economics for coupling a very high-temperature gas-cooled reactor to a variety of process applications. It is concluded that nuclear steam reforming of light hydrocarbons for coal conversion could be a near-term alternative and that direct nuclear coal gasification could be a future consideration. Thermochemical water splitting appears to be more costly and its availability farther in the future than the coal-conversion systems. Nuclear steelmaking is competitive with the direct reduction of iron ore from conventional coal-conversion processes but not competitive with the reforming of natural gas at present gas prices. Nuclear process heat for petroleum refining, even with the necessary backup systems, is competitive with fossil energy sources. The processing with nuclear heat of oil shale and tar sands is of marginal economic importance. An analysis of peaking power applications using nuclear heat was also made. It is concluded that steam reforming methane for energy storage and production of peaking power is not a viable economic alternative, but that energy storage with a high-temperature heat transfer salt (HTS) is competitive with conventional peaking systems. An examination of the materials required in process heat exchangers is made.

Gas reactor international cooperative program: HTR market assessments

Description: The HTR Multiplex utilizes the HTR as an energy source to produce multiple forms of energy. The multiplex technolog is applicable to the following markets: dispersed industrial heat; peaking and mid-range electricity; ammonia and methanol production with methane feedstock; and production of gaseous and liquid fuels from coal. It is estimated that the first two markets will comprise from 300 GW(+) to 400 GW(+) in the 2000 to 2020 time period (about 8 quads per year). For the dispersed industrial heat, the HTR multiplex has a heat cost about half that of fluidized bed combustors (FBC) operating at a capacity factor of 0.3 and about equal to that of FBC's operating at a capacity factor of 0.9. For the peaking and mid-range electric market, the HTR multiplex can supply electric energy at costs three-fourths that of FBC's operating at a capacity of 0.1 and equal to that of FBC's operating at a capacity factor of 0.3. For the ammonia and methanol markets, the HTR multiplex costs are about equal to coal and somewhat higher than methane with current fuel prices. Application to coal refining is similar to the ammonia and methanol markets. Current economic analyses show approximate equivalence for coal and nuclear heat.
