Category: Number 25
Publication: 25
Summary

The paper suggests method for adaptation of WWER “non-design” nuclear fuel  regarding accident modes (including severe accidents leading to fuel damage) based on deterministic evaluations for conditions of stable divergence of “non-design” and design nuclear fuel temperature dependences during accident progress. This method allows determining shortcut list of “non-design” nuclear fuel accidents/accident stages that requires additional detailed modelling and safety analysis. The authors have given preliminary estimate for adaptation conditions of WWER “non-design” plutonium fuel.

Keywords: adaptation, accident, nuclear fuel, water-moderated water-cooled reactor (WWER).
