Sensitivity of HTGR Heat and Power Production to Reactor Outlet Temperature, Economic Analysis
- Idaho National Laboratory (INL), Idaho Falls, ID (United States)
This technical evaluation (TEV) has been prepared as part of a study for the Next Generation Nuclear Plant (NGNP) Project to evaluate the economics of integrating a high-temperature gas-cooled reactor (HTGR) with conventional chemical processes. This TEV addresses the economics of heat and power produced using an HTGR, as well as the effect of increasing the reactor outlet temperature (ROT) on the economic results. These results are preliminary and should be refined as the design of the HTGR progresses, if the design of the HTGR is changed significantly, or if additional refinements of the HTGR capital and/or operating costs become available. The HTGR capital, operating and maintenance (O&M) costs, fuel, and decommissioning costs are based on the correlations and costs presented for a nth of a kind HTGR in TEV-1196 (Idaho National Laboratory [INL] 2011a). The production of heat and power, as well as the effect of increasing the ROT on process results, has previously been addressed in detail in TEV-981 (INL 2011b). In that report, detailed process models for heat and power production using an HTGR were developed, with a range of reactor outlet temperatures from 650 to 950°C, in 50°C increments. This report is a follow-up to TEV-981 and evaluates the economics of heat and power production, employing either a Rankine or Brayton cycle, for ROTs of 700 to 950°C, in 50°C increments for a single 600 MWt HTGR and a four-pack of 600 MWt HTGRs.
