Abstract
This work presents the implementation of the Adjoint Sensitivity Analysis P rocedure for the nonequilibrium, nonhomogeneous two-fluid model, including boron concentration and noncondensable gases, of the RELAPS/MOD3.2 code. Th e end product of this implementation is the Adjoint Sensitivity Model (ASM- REL/TF) which is derived for both the differential and discretized equation s underlying the two-fluid model. The consistency requirements between thes e two representations are also highlighted.
