Title: High temperature gas-cooled reactor: gas turbine application study

Abstract

The high-temperature capability of the High-Temperature Gas-Cooled Reactor (HTGR) is a distinguishing characteristic which has long been recognized as significant both within the US and within foreign nuclear energy programs. This high-temperature capability of the HTGR concept leads to increased efficiency in conventional applications and, in addition, makes possible a number of unique applications in both electrical generation and industrial process heat. In particular, coupling the HTGR nuclear heat source to the Brayton (gas turbine) Cycle offers significant potential benefits to operating utilities. This HTGR-GT Application Study documents the effort to evaluate the appropriateness of the HTGR-GT as an HTGR Lead Project. The scope of this effort included evaluation of the HTGR-GT technology, evaluation of potential HTGR-GT markets, assessment of the economics of commercial HTGR-GT plants, and evaluation of the program and expenditures necessary to establish HTGR-GT technology through the completion of the Lead Project.

  • This HTGR-SC/C Application Study documents the effort to evaluate the appropriateness of the HTGR-SC/C as the Lead Project. The scope of this effort includes the evaluation of the HTGR-SC/C technology, the evaluation of potential HTGR-SC/C markets, the assessment of the economics of commercial HTGR-SC/C plants, and the evaluation of the program and expenditures necessary to establish HTGR-SC/C technology through the completion of the Lead Project. Further, the value of the HTGR-SC/C Lead Project in the support of advanced applications such as the HTGR-R is also addressed. The HTGR-SC/C was considered as a Lead Project candidate in two configurations: a 2240-MW(t)more » baseload electric plant and an 1170-MW(t) cogeneration plant that provides electricity and process steam.« less
  • This Application Study evaluates the HTGR-R with a core outlet temperature of 850/sup 0/C as a near-term Lead Project and as a vehicle to long-term HTGR Program objectives. The scope of this effort included evaluation of the HTGR-R technology, evaluation of potential HTGR-R markets, assessment of the economics of commercial HTGR-R plants, and the evaluation of the program scope and expenditures necessary to establish HTGR-R technology through the completion of the Lead Project. In order to properly assess the potential of the HTGR-R and the suitability of the HTGR-R as a Lead Project, additional work must be performed before amore » final judgment is rendered. Design trade-off studies and alternative applications must be investigated to determine if a commercial potential exists for the HTGR-R at 850/sup 0/C. If commercial incentives are only identified for the HTGR-R with core outlet temperatures greater than 850/sup 0/C, the design and development program duration and cost and the demonstration path for the HTGR-R must be reassessed.« less
  • Since publication of a report on the application of a High Temperature Gas-Cooled Reactor Steam Cycle/Cogeneration (HTGR-SC/C) plant in December of 1980, progress has continued on application related activities. In particular, a reference plant and an application identification effort has been performed, a variable cogeneration cycle balance-of-plant design was developed and an updated economic analysis was prepared. A reference HTGR-SC/C plant size of 2240 MW(t) was selected, primarily on the basis of 2240 MW(t) being in the mid-range of anticipated application needs and the availability of the design data from the 2240 MW(t) Steam Cycle/Electric generation plant design. A variablemore » cogeneration cycle plant design was developed having the capability of operating at a range of process steam loads between the reference design load (full cogeneration) and the no process steam load condition (all electric generation).« less
  • This report, which examines the Gas Turbine-High Temperature Gas-Cooled Reactor (GT-HTGR), derives from related technology assessments initiated in 1976. Those EPRI assessments, which were intended as companions to government-funded reactor commercialization studies, addressed the technical adequacy of a specific steam-cycle HTGR design. The same approach has been utilized herein except as limited by the more conceptual nature of the GT-HTGR. The GT-HTGR has historically been viewed as an international program deriving from U.S. graphite-helium reactor technology and European closed cycle turbomachinery development. In concept the program has been remarkably stable, but schedules and specific designs have been subject to continuingmore » modification largely as a result of changes in national energy policies. The specific purposes of this report are (a) to provide a brief review of the recent international background of the project and (b) to discuss the open issues and technical risks which appeared evident in the technical literature available through 1977. The chronology of GT-HTGR development in both the United States and Europe through 1977 is summarized. A detailed reporting of technical evaluations and verification analyses performed is included.« less
