Measured ratio of radiative capture and fission cross sections of U235 and Pu239 in the resonance region

Correlation between Fission-Channel Effects and Fragment Kinetic Energies

“…5 It is expected that correlations also should exist between A 2 and fragment kinetic energies, and between A 2 and P, the number of neutrons emitted per fission, for higher-energy resonances. Previously available data 6 "* 8 have not shown that such a significant correlation exists, however.…”

“…This work has continued with the establishment of a preliminary framework from which to ana1yze the combinations of loading mechaniSJ1?.8· (deformation modes) which might lead to failure. Conditions a.1d events that produce deformation [8][9][10][11][12][13][14][15][16][17][18][19][20] and/or stress in fuel cladding have been described and discussed in a preliminary manner; relations for predicting the effects of such mechanisms on cladding have been gathered and made available, and those areas needing additional analysis have been identified (Table 8 -6).…”

“…It was proposed that the criterion be based on strain level, which appears more appropriate than stress due to the predominance of secondary stresses, particularly in vented fuel. Such a criterion might be related to a "Damage Index" of the form: As shown in Figure 8-10 the increment of strain would be calculated for each reactor [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22] event, under each deformation mode (combination of loading mechanisms), compared to the ductility under these specific conditions (temperature, fluence, strain rate, etc. ), and the Damage Index determined.…”
