Analysis of Erbia-loaded Critical Experiments in KUCA using AEGIS Cross Section Library

摘要

The erbia-loaded critical experiments performed inrnthe solid moderated core of KUCA are analyzed with thernheterogeneous multi-group cross section generated by thernmethodology of the lattice physics code AEGIS and thernmulti-group Monte-Carlo code GMVP. The k-infinity ofrncell obtained by GMVP well reproduces that obtained byrnthe continuous energy Monte-Carlo code MVP. Therefore,rnfundamental validity of the heterogeneous effective crossrnsection obtained by the AEGIS methodology is confirmed.
