Probabilistic fracture analysis for boiling water reactor pressure vessels subjected to low temperature over-pressure event

► Probabilistic fracture analyses for BWR/RPV under the LTOP event have been performed. ► Low probability of failure for circumferential weld at beltline region can be found. ► In-service inspection on the circumferential welds can be relieved permanently. ► Periodic inspection for axial shell welds is still recommended.
