Advances in Fission Product Yield Evaluation and Modeling

Throughout the past several years, there have been significant advances in modeling and experimental measurements for fission product yields. Facilities have been able to measure fission products with increasingly shorter half lives that can be used to constrain calculations that can consistently model both prompt and delayed fission observables. Here, we describe our modeling framework for calculating independent and cumulative fission products along with prompt and delayed neutron and gamma-ray multiplicities and energies. We discuss this work in the context of the larger multi-institute fission product yield evaluation project that combines the consistent modeling with calculations for the underlying fission fragment initial conditions, new measurements, and corrections to historic data.
