Experimental verification of the behavior of underclad cracks using semi-large scale specimens

Popis výsledku v původním jazyce

During years 2005-2006 a series of semi-large scale experiments of specimens containing underclad (embedded) crack were performed in NRI Rez. The experiments were performed within EU PHARE project in cooperation with VTT, FNS, TVONS (Finland) and Tecnatom (Spain). The aim of the project was to investigate fracture mechanics properties of cladding, in particular to establish the role of cladding in fracture process of the specimens. The specimens were manufactured from an artificially aged material of decommissioned (not operated) RPV of WWER-440 type. During loading, majority of specimens exhibited pop-ins followed by ductile tearing of cladding and final failure. Based on numerical evaluation of experiments, a modification of the procedure used for assessment of RPV integrity was proposed, and was incorporated into the VERLIFE methodology used for lifetime evaluation of WWER type reactors.
