SUBJECT:
TASK B TENDON SURVEILLANCE This item first became a concern during the staff's revie'w 'of the third year surveillanci. report for the ANO-1 containment ungrouted tendons.
ANO-1 Technical Specifications have nc quantitative requirements for tendons or limiting conditions of operation directly related to tendon conditions. Considering that the only Technical Specification require-ment for ANO-1 is to submit a report, it was believed that the best approach to resolve this concern was to implement Standard Technical Specifications (STS) in the area of Tendon Surveillance for ANO-1.
A preliminary survey was made of operating plants.
It was found that Technical Specifications for Tendon Surveillance are not consistant through out all operating plants. Therefore, it was concluded that the Tendon Surveillance Technical Specifications should be upgraded for alt facilities with tendons. However, the current STS for tendons are not considered by the staff to be the most acceptable. Rather, the staff b'elieves that the methods provided by the proposed Revision 3 of Reg Guide 1.35 and Reo Guide 1.35.1 would be more appropriate for implement-ing into Technical Specifications.
I Revision 3 of Reg Guide 1.35 is presently issued for public comment.
Meanwhile, the ASME has drafted surveillance guidelines for tendons in Section XI of the ASME Code. These too are to be issued for comment.
The proposed plan now is to wait until the revision to Section XI of ASME Code has been issued in order that it can be endorsed and included as a part of Reg Guide 1.35 and 1.35.1.
This process will take 12 - 18 months at least.
l Considering all the above, we recomend the following:
l.
Remove Task B-38, Tendon Surveillance frem the multi-plant action item list.
l
- 2.. When Revision 3 of Reg Guide 1.35 and Reg Guide 1.35.1 are issued, identify a new multi-plant issue which would have as a goal to
-8008220%
I implement consistent STS for Tendon Surveillance in all applicabla operating plants. This would be done by issuing a letter to all reactors having tendons as part of the containment structure request-ing the submittal of Technical Specifications. No letters have yet been sent to operating plants requesting any action. Thus, as far as the utilities are concerned, there is no need to inform th,em as to our current disposition of this action item.
