Experimental and calculational results of an irradiation experiment in EBR-II

During the period from 1967 to 1970, several actinide samples were irradiated by ANL in the fast reactor EBR-II for approximately 1023 nvt. In 1978, ORNL began an experimental determination of the exposure products in the irradiated samples, and to date, 12 of the samples have already been analyzed. In a previous paper preliminary experimental results for 239Pu sample were compared with the exposure products predicted by calculations. In this paper, the comparison is extended to samples of 238U, 233U, 232Th, 240Pu, 237Np, and a second 239Pu sample, with the calculations utilizing the recently released ENDF/B-V data and improved modeling approximations. The experimental results presented in this paper represent a fairly comprehensive set of measurements of actinide burnup in a fast reactor spectrum
