FUEL ENRICHMENT FOR THE ENRICO FERMI REACTOR

Technical Report ·
OSTI ID:4226604
The enrichment of the Enrico Fermi core was determined by calculations based on critical experiments and was established at 25.6% contained U/sup 235/ for a total uranium contest of 1734 kg. This enrichment should ensure criticality for a minimum of 91 subassemblies assuming an equllibrium core for a burn-up of one percent. The uncertainty is estimated to be +20 subassemblies, i.e., a range from 91 to 111 subassemblies. The most probable number of subassemblies on initial loading to criticality is 96. (auth)
