(Images or figures aren´t included) The High Temperature Gas cooled Reactors (HTGR) are being accepted by many countries today due to the increase interest as a future energy option. The research on HTGRs are being conducted in China and Japan, and also two new nuclear plant designs are being chased as an international project (4). These reactors are used in nuclear power plants to generate electricity and also new nuclear fuels. However, can these HTGRs be used in residential areas?
Gas-cooled nuclear reactors was originated by a professor in chemistry named Farrington Daniels at 1942 in University of Wisconsin. His report was published in 1944 with features of a direct cycle turbine, plant below grade and pebble bed cores (3). HTGR plant history can be seen from two generation, from 1960 to 1990 and the second generation of Asian plants, both of which are still operating (3).
The first reactor was Dragon in Winfrith, England. This reactor was not made to generate electricity but as a fuel and material test reactor (3). However, Dragon rejected heat to the atmosphere through a bank of fin-fan dry coolers.
The first HTGR to produce electricity was the Peach Bottom reactor in United States as a technology demonstrator from 1966 to 1974 (2). This plant reactor was successful for only 8 years since it was shut down due to it being too small to commercialize (3).
The first reactor built in Germany was the Arbeitsgemeinschaft Versuchreaktor (AVR) (3). It uses the pebble bed…
