Equations were derived giving the spatial distribution of fissionable isotopes as a function of exposure. These are then used to calculate the energy generation in a fuel element as a function of radius and exposure. The results plotted show that the energy generation varies from a simple I/sub 0/ dependence on radius at low exposures toward uniform energy generation at high exposures (10,000 Mwd/t). (auth)
