Abstract

In JAERI, a feasibility study of HTGR-GT has been conducted as an assigned work from STA in Japan since January 1996. So far, the conceptual or preliminary designs of 600, 400 and 300MW(t) power plants have been completed. The block type core and pebble-bed core have been selected 600MW(t) and 400/300MW(t), respectively. The gas-turbine system adopts a horizontal single shaft rotor and then the power conversion vessel is separated into a turbine vessel and a heat exchanger vessel. In this paper, the issues related tot the selection of these concepts are technically discussed.
