The core zone of the Dragon 20-Mwh helium-cooled reactor consists of 37 elements with 7 fuel rcds in each, totaling 259 fuel rcds. A fuel rcd is thorium- uranium fuel surrounded by a graphite box; the assembly is restrained radially by the pressure drop in the coolant channels. For the purpose of keeping activity at low limits, the graphite box is impregnated sufficiently so that diffusion of gaseous fission products is delayed for at least 1 hour, and a gap is intrcduced between the fuel and the box for a small coolant purge. Details of fuel rod construction are given together with heat transfer and thermal stress equations and characteristics. (D.L.C.)
