Description

More than 30 years have been passed since the first nuclear power plant was in operation. Various needs for welding technology have been emerged and the technology has been developed. This paper first describes the key technologies in BWR power plants and then introduces ones in PWR power plants. Welding techniques are introduced in detail. Applications of arc welding, gas tungsten arc welding, electroslag welding, electron beam welding are explained. In order to avoid stress corrosion cracking, water jet and laser peening techniques are used. (author)
