Abstract
Elemental composition and uranium isotope ratios for individual ''hot' ' particles have been obtained by instrumental neutron activation anal ysis. It has been found that maximum U-235 enrichment factor in partic les (K = 3.6; 2.65% U-235) does not differ much from the initial value of loaded fuel (K = 2.8, 2% U-235). From the abundances of fission ra dionuclides the fuel burn-up, depletion factors of Ru and Cs, and fuel content were calculated.
