Systemization of burnup sensitivity analysis code, 2 (Contract research)

Tatsumi, Masahiro*; Hyodo, Hideaki*

The analysis of burnup characteristics is needed to effectively use burnup characteristics data in the actual cores based on the cross-section adjustment method. So far, development of an analysis code for burnup sensitivity, SAGEP-BURN, has been done and confirmed its effectiveness. However, there is a problem that analysis sequences become inefficient because of a big burden to user due to complexity of the theory of burnup sensitivity and limitation of the system. It is also desired to rearrange the system for future revision since it is becoming difficult to implement new functionalities in the existing large system. Therefore, systemization of the burnup sensitivity analysis code has been done with an object-oriented scripting language.
