Summary:

The transition castings and Zircaloy tube structure for the S3G unit cell are secured in position by stainless steel dowel pins. To insure that the dowel pins remain in place, staking pins are placed in both ends of these dowel pins. The original design called for peening around the periphery of the staking pins to secure them. An investigation was carried out to determine lf the staking pins could be heliarc spot welled in place withort exceeding 400 deg F temperature at the points of contact between the stainless steel dowel pin and the Zircaloy tube structure. It is concluded that the staking pins could be heliarc spot welded in place when good timing and welding control are us ed. (auth)
