Therefore, retention of its reliability is a key technique for the life-time maintenance of nuclear power plant.
Furthermore, the reliability of ultrasonic ISI is influenced by the inspection environment, material characteristics and types of defect.
As for the specimen, pipe-to-pipe specimen identical to the weld specimen used in nuclear power plant was developed on two piping specimen with different dimensions and materials, one of which was processed with different sizes and shapes of EDM notch on two welding parts and the other with fatigue crack and EDM notch.
Specimen materials were 304L stainless steel SA312 and TP347 stainless steel.

Life cycle analysis is used to evaluate the product throughout its life cycle, from raw material acquisition and disposal of production, technology and methods of environmental impact.
LCA demands a detailed study of each unit process energy demand, raw material use, production, transportation, and other activities in its life cycle that may be caused by environmental issues.
