HTGR high-temperature, gas-cooled

The metal is a source of nuclear power. There is probably more energy available for use from thorium in the minerals of the earth s crust than from both uranium and fossil fuels. Any sizable demand from thorium as a nuclear fuel is still several years in the future. Work has been done in developing thorium cycle converter-reactor systems. Several prototypes, including the HTGR (high-temperature gas-cooled reactor) and MSRE (molten salt converter reactor experiment), have operated. While the HTGR reactors are efficient, they are not expected to become important commercially for many years because of certain operating difficulties.

Thorium makeup requirements for one reactor system, the HTGR (high-temperature gas-cooled reactor), may be estimated from Fig. 3.33. A 1000-MWe HTGR requires 7.4 MT of thorium as feed pet year. Reprocessing recovers 6.8 MT, which can be recycled after storage for 20 to 30 years to permit excess Th to decay. The net thorium consumption of a 1000-MWe reactor then is 0.6 MT/year. Thus, the 441,000 MT of U.S. ThOa thorium reserves listed in Table 6.14 would provide thorium fuel for...

The concept of HTGR (High Temperature Gas-Cooled Reactor) plant with Closed Cycle Gas turbine is taking an increasing interest because of its unique characteristics such as highly excellent safety and high thermal efficiency which reaches about 50 percents. The necessity of the demonstration test of the full scale power conversion module to be used in this plant has been pointed out. This paper presents a new proposal of demonstration test facility concept. 

All data from actual operations, except for the LS-VHTR. Nominal and peak (in parenthesis) allowable temperatures during fuel-handling operations are shown. LWR = light-water reactor HTGR = high-temperature gas-cooled reactor AGR = advanced gas-cooled reactor LMR = hquid-metal reactor MSR = molten salt reactor, AHTR = Advanced High-Temperature Reactor.
