The two failure mechanisms of most concern in nuclear reactor pressure vessels are brittle fracture and low-cycle fatigue. Steel selection and fabrication history determine the properties of the vessel prior to service. The ability to detect defects incident to vessel fabrication is an important factor in fracture consideration. Suggestions are made relative to an engineered selection of nondestructive-test requirements dependent on stress level.
