Available in PDF, EPUB and Kindle. Book excerpt: The fission product inventory and the decay heat associated with driver fuel irradiated to goal exposure (45,000 MWd per metric ton) in the Fast Test Reactor is presented, based on calculations using the computer code RIBD with a nuclear data library prepared for the FTR environment. Curie inventories as a function of decay time are given for each of about 350 isotopes or isomeric states generated by the fast-neutron induced fission of either 239Pu or 238U, by down-chain decay, or by subsequent neutron capture. Beta, gamma, and total decay power are given in percent of operating power for decay times from 1 sec to about 10 years. Uncertainty in the decay heat calculations, based on propagation of the uncertainties associated with input nuclear data, is estimated. The uncertainty is calculated to be less than +̲ 10% for the first 10 days, and less than +̲ 20% over a 10-yr decay period.

This book was released on 1976 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Preliminary experimental information for beta-ray energy release from fission product decay following thermal-neutron fission of 235U has been obtained for cooling times between 3 and 14,400 secs. The data were obtained as pulse-height spectra for beta energies between 0.25 and 8 MeV using a two-crystal scintillation spectrometer, and were unfolded to give beta-ray energy spectra of moderate resolution. Two irradiation times, t/sub i/ = 2.4 and 100 sec, were studied. The energy release data were studied. The energy release data were obtained by integrating the observed spectra and then estimating the contribution for E/sub .beta./ less than 0.25 MeV. Difficulties encountered in this first experiment using the beta-ray detection equipment are discussed. Previously reported preliminary gamma-ray spectra have been compared with spectra calculated using spectral information in the ENDF/B--IV data file for approximately 180 fission products. Several comparisons are presented for t/sub i/ = 100 secs. As expected the comparison is not very good for short cooling times, but is encouraging for t/sub cool/ approximately 2000 secs.

Available in PDF, EPUB and Kindle. Book excerpt: By use of currently available experimental and calculated fission productyields from fast fission 239Pu, the fission product code, FPIC, has been expanded to include the capability of calculating fission product decay powers for 239Pu fast fission. The revised code, FPIC/U-Pu, is operational on the CDC-6600 computer. Summation calculations of beta, gamma, and total decay powers from 235U thermal fission and from 239Pu fast fission were compared for both an instantaneous burst and infinite irradiation. Shutdown times ranged from 10 to 109 sec, and significant (>10%) differences occur principally for very shortand very long shutdown times. The decay powers from 235U thermal fission were compared with previous studies for an instantaneous burst and for infinite irradiation, and good agreement was found over the applicable shutdown times. Calcualations of beta, gamma, and total fission product decay powers from 239Pu fast fission for a specific irradiation history were then compared with the corresponding experimental measurements by K. Johnston of AWRE, as well as with 235U thermal fission calculations. For gamma and total decay power, the 239Pu fast fission calculation generally agreed better with the experiment, whereas for beta decay power, the 235U thermal fission calculations were generally better. Similar conclusions were drawn from comparisons of instantaneous burst calculations with the corresponding analytical fits derived from the experimental data.
