This report describes the application of a high-temperature gas-cooled reactor (HTGR) which operates in a process steam/cogeneration (PS/C) mode in supplying heat and electricity to a large steel mill. The technical and economic merits of an 1170-MW(t) HTGR-PS/C are compared with those of a coal-fired plant for this application. The utility requirements of the steel plant were estimated to be 296 MW(t) as steam at 5.0 MPa (725 psia) and 240 MW(e), which leaves a surplus of energy from the reference nuclear plant design. Cycle diagrams were prepared for two plants: Case 1 having maximum cogenerated steam and Case 2 having maximum cogenerated electricity. The HTGR-PS/C appears economically favorable, based on a 30-year economic life of the thermal energy source. The safety and licensing issues of the nuclear plant were reviewed.
