TRANSMITTAL OF RISKED BASED INSERVICE TESTING INFORMATION REQUESTED BY NRC REF:
- 1) TV Electric Letter logged TXX-96439, from C. L. Terry to l
the NRC, dated August 22, 1996
the NRC, dated June 3, 1996 1
l Gentlemen:
l On April 25, 1996, the NRC staff met with representatives from TU Electric to discuss the licensee's November 27, 1995,. risk-informed Inservice Testing (IST) submittal and the NRC staff's March 15, 1996, request for additional information (RAI).
During the meeting, TU Electric agreed to provide the staff with the a list of less safety significant components i
that are not exercised during the course of a normal refueling cycle.
i Based on an initial review, a list of valves was identified and transmitted to the NRC by Reference 1.
As noted by Reference 1. TV Electric is providing a revised list of valves. Reference 1 stated that a revised list would be provided by September 9,'1996. As a result of l
conversations with Tim Polich of the NRC staff on September 9, 1996, the transmittal of the revised. list was extended until September 13, 1996.
I
. A review was conducted of the less safety significant valves which have a
. proposed test schedule of 6 years (as noted by Reference 2).
Those valves which are not exercised during the course of a normal refueling cycle have been identified (See Attachment). The Attachment to TXX 96458 supersedes i
the Attachment to TXX 96439.
