Abstract

The special meeting focused on the Implementation of the Hauser-Feshbach theory for Fission Product Yield (FPY) Evaluation and Fission Modelling was held at IAEA Headquarters in Vienna from 13 to 17, January 2020, as a joint effort among JAEA, LANL and IAEA Nuclear Data Section. The meeting was a preparatory work toward new FPY data libraries planned at each institute. We discussed implementation of the Hauser-Feshbach statistical decay model to calculate the de-excitation of fission fragments, and performed intercomparison of the available three codes at each institute - CCONE (JAEA), CoH/BeoH (LANL), and TALYS (IAEA). The discussions include types of fission observable to which we can produce by our models, estimation of initial fragment configurations (after scission and before prompt particle emission), and future development of these codes to make them applicable for the FPY data evaluation.
