FORMATION OF U-232 DURING THE IRRADIATION OF THORIUM
Technical Report
·
OSTI ID:4332896
The formation of U/sup 232/ by (n,2n) reactions in pileirradiated thorium is discussed. For thorium irradiated in a heterogeneous reactor, the total U/sup 232/ formed is produced by fast neutrons from two sources: (a) those which originate in the surrounding fuel elements, and (b) those produced by the fissioning of U/sup 233/ in the thorium itself. A Monte Carlo calculation is used to estimate the effective (n,2n) flux in heavy water or graphite surrounding a point source of fission neutrons. The results for the point source are integrated to give the effect of a line source or, approximately, a fuel rod. (auth)
