| Summary: | A study was performed to determine the delayed neutron actinide samples (provided by Oak Ridge National Laboratory), alternate group structure. Using a set of highly purified computer control and counting system, and a specially designed in-core irradiation device. The values for the determined to be 1.67 ︢0.08, 1.14 ︢0.07, 0.86 ︢0.05, emission properties from fast fission of several actinide found in all cases. The "seven-group" structure was shown to group" structure, in contrast to the traditional "six-group" groups and their associated delayed neutron precursors. microscopic method was used to predict initial guesses for neutron induced fission of U-235, Np237, and Am-243 were Np-237, and Am-243. A calculational technique based on the other values recommended by Keepin et al., Waldo et al., provide a more direct correlation between delayed neutron Reactor, a quick pneumatic transfer system, an integrated respectively. The newly measured values were compared with Saleh et al., and Brady and England. Good agreement was six groups of the "seven-group" structure were measured for structure used previously, was suggested which would yield a superior fit to the measured data. A series of measurements the delayed neutron emission decay constants and yields for the delayed neutron parameters (group decay constants and total delayed neutron yield (per 100 fissions) from fast- U-235, Np-237, and Am-243. These experiments were performed using the Texas A&M University Nuclear Science Center waste isotopes. The specific isotopes evaluated were U-235, were performed to test the hypothesis suggested by this yield a superior fit to the measured data, as well as, yields). Based on these calculations, an alternate "seven- |
