- This paper presents an investigation of Ignalina NPP reactor’s main circulated circuit (MCC) pipeline welded joints materials fracture toughness properties. Standard compact C(T)-1T specimens containing “V” and “K” – type welds were cut off from the various MCC pipe’s zones, produced from the 19Mn5 steel pipe and welded by electrodes UTP-068HH, YONI-13/55 and CT-36. Critical J – integraf JIc values were defined Rusing J–R curve test method, which results on determination of J – integral values as a function of crack extension ?a. The investigation enables to calculate critical crack length ?amax and ?ac sizes and J – integral JIc, Jmax and JPmax values, which are used to predict safe service lifetime of the cracked pipelines.
