The Simulation of a Criticality Accident Excursion Occurring in a Simple Fast Metal System Using the Coupled Neutronic-Hydrodynamic Method
- Los Alamos National Laboratory (LANL), Los Alamos, NM (United States)
Analysis of a criticality accident scenario occurring in a simple fast metal system using the coupled neutronic-hydrodynamic method is demonstrated by examining the last Godiva-I criticality accident. The basis tools and information for creating a coupled neutronic-hydrodynamic code are presented. Simplifying assumptions and approximations for creating an idealized model for the Godiva-I system are discussed. Estimates of the total energy generation and the maximum attainable kinetic energy yield are the most important results that are obtained from the code. With modifications, the methodology presented in this paper can be extended to analyze criticality accident excursions in other kinds of nuclear systems.
