Get this from a library. Sensitivity theory applied to a transient thermal-hydraulics problem. [C F Weber; Edward Oblow; Union Carbide Corporation. Computer Sciences Division.; Oak. 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. A new method for sensitivity analysis of transient nonlinear problems is developed and applied to a reactor thermal-hydraulics problem.

The method resembles the differential sensitivity methods currently used in the linear problems of reactor physics, but it is applicable to nonlinear systems as well. A sensitivity theory based on reactor physics experience was successfully developed for a reactor thermal-hydraulics problem. The new theory is derived for the case of non-linear, transient heat.
