A generalized perturbation theory program for CANDU core analysis

A generalized perturbation program GENOVA has been developed for the purpose of various applications to Canada deuterium uranium (CANDU) reactor physics analyses. The program was developed under the framework of CANDU physics design and analysis code RFSP. The generalized perturbation method was implemented to estimate the power dis- tribution in conjunction with the zone controller level. The numerical algorithm of the gen- eralized perturbation method was veri®ed by a simple 2 2 node problem. The capability of predicting the zone controller level was validated for a CANDU-6 reactor refueling problem. GENOVA is compatible with the current CANDU physics design code and, therefore, it can be used for advanced CANDU core analysis and fuel development in the future
