Restructuring of burnup sensitivity analysis code system by using an object-oriented design approach

Yokoyama, Kenji; Ishikawa, Makoto; Tatsumi, Masahiro*; Hyodo, Hideaki*

In this work, a new burnup sensitivity analysis code, PSAGEP, has been developed with help from the object-oriented technique and the scripting language Python. It was confirmed they are powerful to support complex numerical calculation procedure for burnup sensitivity analysis. PSAGEP was reborn from the conventional hard-to-use code system as a user-friendly code system which can calculate the sensitivity coefficients of the nuclear characteristics considering burnup effect to cross-section changes based on the generalized perturbation theory.
