Abstract

Abstract

During rod drop transient,the interaction between pellet and cladding increases instantly,which may leads to failure of fuel rod.This paper introduces the mechanism and quantative method to analyze PCI during transient II,with which the PCI thermal-mechanical analysis has been carried out for the 18-month fuel cycle management of GNPS.The results show there are enough stress margins for the base load operation and primary frequency control operation if rod drop accident occurs in the natural cycle and stretch out operation,therefore no risk of PCI failure has been found.
