An Evaluation Of Effective Plutonium Cross Sections In Reactivity Calculations PDF Download

The EBWR Plutonium Recycle Experiment has been initiated to provide data for the creation of a computational model that will permit accurate prediction of isotopic behavior and reactivity changes with burnup for plutonium-fueled, light-water, thermal reactors. A preliminary model, described in this report, has been tested against data from a number of cold critical experiments. Data from hot critical and from the EBWR central plutonium region at various burnups are necessary before a complete model can be formulated.
