post installation, and inservice inspections of the sleeves and sleeved These specifications should include inspection techniques, tubes.
inspection frequencies, and reporting requirements.
Since the sleeves will not function as a part of the primary pressure boundary, it is our understanding that the 40% plugging criteria will remain in effect unless otherwise justified.
Describe the procedures t' hat will be used to ensure the quality of 2.
the retaining collar to tube welds.
Discuss how the operating time of the t=tellite test fixtures in the i
