INTRODUCTION l
Inservice Inspection Examinations of ASME Class 1,2, and 3 piping welds and components were conducted at Seabrook Station in accordance with ASME Section XI, 1983 Edition through Summer 1983 Addenda and the ISI Program Plan. This report summarizes ISI examinations completed just prior to and during the fourth refueling outage which concluded on December 11,1995. ISI Period 2 is complete with approximately 58% of the Interval 1 examinations completed.

SUMMARY
1.0 NONDESTRUCTIVE EXAMINATION PROCEDURES The following procedures were used during refueling outage #4 inservice inspection. Three procedures utilized (VT, PT, and MT) were North Atlantic Energy Service Corporation (NAESCO) procedures. The remaining procedures used were Yankee Atomic Electric Company (YAEC) procedures approved for use by NAESCO Station Operation Review Commitee (SORC). YAEC serves as the certifying agent in NDE for NAESCO.

ASME Clau 3 & NF D-A During conduct of the Class 3 CS System - Boric Acid Transfer Functional Test, boric acid was discovered on a weld. The boric acid was removed and the weld examined by liquid penetrant and by VT-2. No unacceptable indications were found. The source of the boric acid was identified to be from a packing leak on an overhead valve.
D-C The Class 3 Spent Fuel Pool Cooling System Functional Test discovered a socket weld that was defective. The line was repaired and successfully re-examined.
N-F Several component supports were identified as having minor problems (i.e.
clearances, gaps, etc.). Evaluations were performed and the supports were determined operable, and did not fall within IWF-3410.

- 15. Abstract of Corrective Measures Welds No corrective measures were required as a result of UT examinations. All recorded indications were evaluated and verified to be related to geometry and weld metal I
structure.
Several surface examinations exhibited unacceptable linear indications which appeared to be non-relevant conditions. Further surface conditioning verified the non-relevant condition and yielded an acceptable re-examination.
Bolted Components A nut was found loose on a valve bonnet. The condition was corrected and i
successfully re-examined. In addition, the required sample expansion yielded no unacceptable results.
Pressure Testing A defective weld was discovered during conduct of a functional test on the Spent Fuel Pool Cooling System. The weld was repaired and the line was successfully tested.
- Boric Acid was found on a weld during conduct of a functional test on the CS -
Boric Acid Transfer System. The deposit was removed and the weld examined by liquid penetrant examination and by VT-2. No unacceptable indications were found. The source of the boric acid was identified to be from a packing leak on an overhead valve.
Comnonent Supoorts No corrective measures were required as a result of component support visual examinations. Clearance and gap discrepancies were evaluated by Engineering as acceptable.
