(Received June 17,1997)
A study of bumup analysis method for the irradiation test of Rock-like Plutonium Fuel sample
has been performed. The samples have been irradiated in the irradiation hole in the beryllium
reflector of JRR-3. Computer codes used for the analysis are SRAC, ORIGEN2 and MVP. In the
calculation using the SRAC code, fine energy group neutron spectrum of the beryllium reflector is
calculated. Bumup calculation of the irradiation capsule is done using the spectrum as a boundary
source into the capsule. In the bumup calculation for the capsule, two kinds of simple and detailed
models are considered and the results calculated are compared and discussed. Some calculations
are also performed with the ORIGEN2 code and the results are compared with those calculated by
SRAC. The accuracy of the results calculated with the SRAC code is examined as comparing with
those obtained rigorously by the continuous energy Monte Cairo code MVP.
