Mr. Richard A. Uderitz Vice President - Nuclear P. 0. Box 236 Hancock's Bridge, NJ 08038 Gentlemen:

Subject:
Salem Unit 2, First Periodic Containment Integrated Leak Rate T*est A meeting on this subject was held between our staff and Mr. F. Meyer and others of your staff on February 1,1983._at the NRC RegionI'off.i.ce.
At this meetii:ig;,we recommended that PSE&G perform the first periodic Integrated Leak Rate Test (ILRT) on Unit 2 during the current refueling outage fof the following reasons:
- 1.
If postponed to the next refueling outqge (June, ~984), 5t years would elapse between the preoperational ILRT (December~/1978) ang/the first periodic ILRT.
This interval is considerably longer than t,he' nominal )~l/3 years between tests required by 10 CFR 50 Appendix J or the 40+/- 10/months required by the plant *Technical Speci-fications during the plant service period.
- 2.
The results of Local Leak Rate Testing (LLRT) conducted so far, though compre-hensive and well within acceptance limits, do not provide positive assurance of an acceptable overall containment integrated leakage rate. This is due to the lack of a definite correlation between the resalts of LLRT and ILRT.
Only an ILRT can provide such assurance.
Thus far, there has been one ILRT conducted prior to operation of Unit 2.
Further, the scope of LLRT has been increased recently at Salem.
This makes correlation of LLRT and ILRT results difficult and, from an engineering point of view, urges performance of an ILRT to demon-strate the comprehensive scope of LLRT.
- 3. The latest industry standard on containment testing, ANSI/ANS-56.8-1981, recommends that the first periodic ILRT be conducted at the first refueling outage, but not more than three (3) years subsequent to the preoperational ILRT.
The difficulties of scheduling this ILRT and compliance with the many requirements were recognized and discussed.
To address the administrative problem of compliance with the schedule interval of Technical Specification 4.6.l.2.a, my staff has initiated action to obtain a one-time waiver for these interval requirements.
