Application of generalized perturbation theory to fast reactor safety sensitivity studies

PDF Version Also Available for Download.

Description

A new sensitivity analysis method based on generalized perturbation theory is applied to a typical fast reactor safety code. The adjoint equations are provided for the coupled, nonlinear, conduction--convection equations as they are implemented in MELT-IIIA. An expression for the sensitivity of any temperature to problem input data is presented. In this initial application of the new methodology, two simple transient problems for the Fast Flux Test Facility are considered. Sensitivity results for various temperature responses to all thermal input data are presented. Conclusions are drawn about the practicality and advantages of developing this new sensitivity methodology. Comparisons of perturbation ... continued below
