4.18.6 Reoorts Following each inservice inspection of steam generator tubes, the complete results of the inspection shall be reported to the NRC.
This report, to be submitted within 45 days of inspection completion, shall include:
a.
Number and extent of tubes inspected; b.
Location and percent of wall-thickness penetration for each indication of an imperfection; and c.
Identification of tubes plugged and tubes sleeved.
This report shall be in addition to a Special Report (per Specification 6.12.5.d) required for the results of steam generator tube inspections which l fall into Category C-3 as denoted in Table 4.18-2.
The Commission shall be notified of the results of steam generator tube. inspections which fall into Category C-3 prior to resumption of plant operation. The written Special Report shall provide a description of investigations conducted to determine cause of the tube degradation and corrective measures taken to prevent recurrence.
Bases The surveillance requirements for inspection of the steam generator tubes ensure that the structural integrity of this portion of the RCS will be maintained. The program for inservice inspection of steam generator tubes is based on a modification of Regulatory Guide 1.83, Revision 1.
Inservice inspection of steam generator tubing is essential in order to maintain surveillance of the conditions of the tubes in the event that there is evidence of mechanical damage or progressive degradation due to design, manufacturing errors, or inservice conditions that lead to corrosion.
Inservice inspection of steam generator tubing also provides a means of characterizing the nature and cause of any tube degradation so that corrective measures can be taken.
