Fast reactor fission yields for /sup 233/U and /sup 235/U irradiated in Row 4 of EBR-II

Calculation of the energy dependence of fission fragments yields and kinetic energy distributions for neutron-induced 235U fission*

“…Figure 5 shows a comparison of the calculated fission yield data of 95 Zr with data published by Gooden [9], Chapman [32], Glende [33], and Laurec [8], as well as with data calculated using the G4ParaFission Model. Within the 0-1 MeV range, the calculated values are in good agreement with Glende's experimental data, which demonstrates a fitted energy dependence of -0.19 per MeV.…”

“…Figure 6 shows a comparison of the calculated fission yield data of 99 Mo with data published by Gooden [9], Chapman [32], Glende [33], and Laurec [8], as well as with data calculated using the G4ParaFission Model. The data from Gooden, Glende, and Chapman, and the calculated data for 99 Mo suggest a flat energy dependence extending to an incident neutron energy of at least 9 MeV.…”

Fission Product Data Measured at Los Alamos for Fission Spectrum and Thermal Neutrons on 239Pu, 235U, 238U

“…The mass spectrometry measurements by Maeck et al (1977Maeck et al ( , 1981 made in the EBR-2 fast reactor, which had an average energy causing fission of 200-400 keV [93][94][95][96][97]. These data were accepted by the ENDF community [98] as generally the most comprehensive and accurate data for defining FPY, often reaching accuracies of approximately 1%, and consequently the ENDF/B-VI database in general has evaluated results very close to Maeck's data.…”

Systematics on fission fragment mass distribution of neutron induced 235 U fission

“…The following experimental fragment mass distribution or chain yield data were used as the base of the systematics: Hambsch in the energy region from 0.5 to 6.0 MeV by a step 0.5 MeV; R. B. Strittmatter [2] , G. Diiorio [3] , G. Siegert [4] at thermal energy; W. J. Maeck [5] at 0.4 MeV; J. W. Mandler [6] at 9.0, 15.0 MeV; BAO Jie [7] at 19.1 MeV and FENG Jing [8] at 22.0 MeV.…”
