Originální abstrakt

The subject of this report is to assess different rates of cooling the bottom of the collector region, specifically the outer surface of the weld JS1200 (also known as weld 111) and the surrounding area. Based on the experience from Russia (OKB Gidropress) it is possible by external cooling of the outer surface of the weld area to reduce tensile stresses in the weld and in the outer radius of collectors pockets, or even change them into compressive stresses. The presence of tensile stresses in the outer radius of collectors pocket in combination with a corrosive environment in the collectors pocket support the possibility of crack initiation and propagation mechanism of stress corrosion cracking (SCC).
