The rationale for the technical details leading to the selection of tubing and tubesheet specifications and inspection techniques was based upon the desire to optimize the chances of success for the CRBRP steam generators. Fabrication processes, especially welding for the tube-to-tubesheet joints were recognized as critical. Thus, heavy emphasis was placed upon the development of reliable welding techniques as well as inspection methods using the most accurate and sensitive tools available. Accomplishments to date include: a) the procurement of the tubing and tubesheets, to the desired specifications; b) validation that the design base properties of VAR and ESR wrought products are well within the Code aceptable levels; and c) development of welding and tube-to-tubesheet inspection methods to provide satisfactory levels of quality.
