STAFF-5, a Two-Dimensonal Computer Model for Simulation of the Performance of Spent Fuel in Storage/Disposal

摘要

STAFF-5, (Spent Fuel Temperature and Cladding Failure Forecaster), a two-dimensional model of a light-water reactor (LWR) fuel assembly in a canister, has been developed to predict spent fuel temperature and study cladding performance during long-term storage and/or disposal. When symmetry of the storage configuration is considered, STAFF-5 provides three-dimensional simulation of the fuel assembly and canister. The heat transfer portion of STAFF was validated against experimental results from instrumented tests of fuel assemblies in selected disposal configurations. (ERA citation 06:034361)
