Summary
Satisfactory methods were developed for penetrating the stainless steel burst-slag-detection tubes and stainless steel-clad thermocouples through the carbon steel pressure shell of the Experimental Gas-Cooled Reactor (EGCR). The burst-slug-detection system permits the positive identification of a channel containing a defective fuel element. while the thermocouples will be used to measure temperatures from numerous points within the reactor. Both types of penetrations require the welding of relatively thin-walled compenents to thicker members under conditions of very limited accessibility. Suitable joint designs were determined and adequate fabrication and inspection procedures established in the construction of prototype demonstration assemblies. Conventional welding and brazing equipment and joining procedures were used throughout. Although accessibility in this application is definitely limited, it appears that welds and brazes of high quality can be made if carefully trained operators are utilized. (auth)
