A generalized perturbation theory program for CANDU core analysis

A generalized perturbation program GENOVA has been developed for the purpos e of various applications to Canada deuterium uranium (CANDU) reactor physi cs analyses. The program was developed under the framework of CANDU physics design and analysis code RFSP, The generalized perturbation method was imp lemented to estimate the power distribution in conjunction with the zone co ntroller level. The numerical algorithm of the generalized perturbation met hod was verified by a simple 2x2 node problem. The capability of predicting the zone controller level was validated for a CANDU-6 reactor refueling pr oblem. GENOVA is compatible with the current CANDU physics design code and, therefore, it can be used for advanced CANDU core analysis and fuel develo pment in the future.
