Dragon, reactor

The HTGR designed by the General Atomic Company and constructed at Peach Bottom, Pennsylvania, U.S.A., was a 40 MW(e) experimental power plant which was similar in many respects to the Dragon reactor. Peach Bottom started commercial operation on June 1, 1967, and ceased operation on October 31, 1974 [36]. The major performance parameters of the Peach Bottom Reactor are shown in Table 8. 

Experience of the Th -U cycle was first obtained in the Indian Point boiling water reactor, where the first core, loaded in 1962, contained pellets of urania-thoria mixture. The main interest, however, has centered on its use in the high-temperature gas-cooled reactor (HTGR), and thorium has been employed as fertile material both in the prismatic fuel elements of the Dragon reactor in the United Kingdom and the Peach Bottom reactor in the United States, and in the spherical elements of the pebble-bed AVR in West Germany. There is also a possibility of adopting the thorium cycle in the...

Although benzoic acid occurs naturally in some substances, such as gum benzoin, dragon s blood resin, balsams, cranberries, and the urine of the ox and horse, the product is made on a large scale by synthesis from other materials. Benzoic acid can be manufactured by the liquid-phase oxidation of toluene by air in a continuous oxidation reactor operated at moderate pressure and temperature ... 

In Japan, the Oarai Gas Loop No. 1, OGL-1, installed in the JMTR, was used for cesium and iodine plateout distribution measurements basically under the normal operating conditions of the HTTR. Within a joint German/French effort, another plateout experimental series was conducted in the in-pile loop SAPHIR in the French PEGASE reactor. Also extensive plateout distribution data were obtained in the UK by examining components removed from the Dragon HTGR...

Several development programmes led to demonstration of high temperature gas cooled reactor features, in particular the coated fuel concept. This has been based on the Dragon project in the UK, Peach-bottom Nol and Fort St. Vrain in the US and the THTR in the Federal Republic of Germany. Currently, the HTTR, of the prismatic type, in Japan will be the first to be used for a process heat application with an outlet temperature of 850°C or above.
