• Attachment A PSE&G Commitments for LER 272/95-023 The following item represents PSE&G commitments made to the Nuclear Regulatory Commission related to LER 272/95-023.

The commitments are as follows: Salem Unit #1 1 A structural integrity assessment is being performed to confirm that affected tubes in their as-found condition meet the requirements of Reg. Guide 1.121. 2. Data analyst guidelines specific to Salem Units 1 and 2 are being developed.

Prior to performing any S/G ECT inspections in either Unit #1 or Unit #2, all analysts will be trained and tested to demonstrate proficiency in the use of the guidelines.

3. A full length bobbin coil ECT inspection expansion of all unplugged tubes in all steam generators from the current 20% sample size will be performed to assure that all bobbin coil probe indications are analyzed during the current outage. The 1993 bobbin coil probe data will be reviewed for any additional pluggable indications identified in the current outage to assess the apparent growth rate of indications.

This expanded inspection scope may identify additional bobbin coil probe indications which should have been analyzed as pluggable in 1993. This task will be completed by March 29, 1996. 4. All bobbin coil inspection data already taken will be reanalyzed.

A PSE&G Level III examiner will provide oversight of this reanalysis effort. This task will be completed by March 29, 1996. 5. Steam generator tubes requiring plugging will be plugged based upon the results of tasks 3 and 4 prior to restart of Unit #1. Salem Unit #2 6. The corrective action described in item 2 above for site specific training and testing will be implemented prior to performing ECT on Salem Unit #2. 7. Salem Unit #2's steam generators will have completed 100% tube inspections prior to Unit #2 restart. If a defective tube was missed in a prior outage, the planned inspection program should detect the defective tube and a supplement to this LER will be issued.
