One and Two-Dimensional Excursion Modeling of GODIVA-IV and CALIBAN Using the MRKJ Code
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States). Advanced Nuclear Technology Group N-2
A technique is described that presents how to perform 2-dimensional nuclear excursion simulations of GODIVA-IV and CALIBAN using the coupled neutronic-hydrodynamic method as part of the MRKJ code to study metal criticality excursions. The 2-D thermoelastic equations were incorporated into the MRKJ code to extend the physics and modeling effort into 2-D (cylindrical) geometry. By making some simplifying modeling assumptions, results were obtained for controlled prompt-critical excursions of GODIVA-IV and CALIBAN. These results will be compared later to legacy data and future measurements that are to be made with both critical assemblies as part of a joint collaboration between CEA/Valduc and US DOE/Los Alamos National Laboratory to improve computational tools to study metal criticality accidents.
