SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION L
SUPPORTING AMENDMENT NO. 85 TO FACILITY OPERATING LICENSE NO. DRP-75 PUBLIC SERVICE ELECTRIC & GAS COMPANY PHILADELPHIA ELECTRIC COMPANY DELMARVA POWER AND LIGHT COMPANY ATLANTIC CITY ELECTRIC COMPANY l
SALEM GENERATING STATION, UNIT NO. 2 k
DOCKET NO. 50-311 i
1.0 INTRODUCTION
By letter dated September 25, 1989 Public Service Electric & Gas Company requested.an amendment to Facility Operating License No. DPR-75 for the Salem Generating Station, Unit No. 2.
The proposed amendment would revise
)
the techtdcal specifications (TS) to extend the test interval for the last of toree containment integrated leak rate tests (CILRT) for Salem 2 from 40 t10 months to the 10-year inservice inspection outage (Cycle 6),
a period of about 59 months.
2.0 EVALUATION I
Paragraph III.D.1(a) of Appendix J states "After the preoperational leakage rate test, a set of three Type A tetts shall be performed at approximately equal intervals during each 10-year service period. The third test of each set shall be conducted when the plant is shutdown for L
the 10-year plant inservice inspections.".In addition to the above quoted
[
Appendix J requirement, Section 4.6.1.2.a of the Salem Unit 2 TS also specifies that "Three Type A tests shall be conducted at 40 +/- 10 month intervals during shutdown at design pressure (47 psig) during each 10 year L
service period. The third test of each set shall be conducted during the shutdown for the 10-year plant inservice inspection (ISI)."
In the September 25, 1989 submittal, the licensee stated that the third i
l Type A test would be required during the next refueling outage of Salem Unit 2 (i.e., Cycle 5, from 3-31-90 to 5-14-90) in order to prevent 1.
exceeding the 50-month limit on the TS maximum interval between Type A L
tests.
However, subsequent testing during the Cycle 6 outage would l-violate the TS minimum 30-month test interval requirement. The plant's 10-year ISI outage (Cycle 6) is presently scheduled for 9-21-91 to 11-24-91. Therefore, the licensee proposed to postpone the CILRT to allow l
the third Type A test to be completed during the plant 10-year ISI outage l
(i.e., Cycle 6 refueling outage).
The licensee provided the following justification to support its proposed amendment:

1.
The intent of the established testing intervals is to conduct three equally spaced Type A tests in a 10-year inservice period with the third test parformed in conjunction with the INyear inservice L
inspection outnoe.-
I 2.
The previous two Type A tests were completed successfully. There have not been any plant modifications which wculd impact containment 1
integrity since the last Type A test.
L 3.
Previous local leakage tests (Type B and C tests) have been completed satisfactorily and on schedule. Operability of the containment isolation valves and penetrations as required by current plant TS would continue to ensure containment integrity during an extended-test interval.
4.
This is a one-time Type A test interval extension request. A new Type A test schedule will be preplanned for the next 10 years.
The staff has reviewed the licensee's submittal and finds that the first CILRT for Salem Unit 2 was conducted on a shortened interval (about 21 inonths from the date of commercial operation). This necessitated the licensee's request for extending the third CILRT interval in order to coincide with the plant's 10 year 151 schedule. Since the licensee has planned to conduct the third CILRT during the scheduled shutdown for the 10 year ISI and because the licensee has justified the leaktight integrity of the containment based on previous leakage test results, the staff concludes that a one-time delay of approximately 9 months beyond the maximum permitted test interval will not, for reasons stated above, have a significant safety impact. The staff, therefore, concludes that the licensee's requested test interval exemption and the associated TS changes for delay in conducting thJ third CILRT are acceptable, 3.0- ENVIRONMENTAL CONSIDERATION i
This amendment involves a charge to a requirement with respect to the l'
installation or use of a facility component located within the restrictec area as defined in 10 CFR Part 20 and chanaes to the surveillance requirements. The steff has determined that the smendment involves na u
significant increase in the amounts, and ne significant char,gt. in the types, of any effluents that may be released offsite and that there is no significant increase in in m i M i et are'rtivt recq n hi t' 1h"';
exposure. The Commission has previously i~ sued a proposed finding that s
this amendment involves no signif kant Lazards consideration and there has been no public contr.ent on such finding. Accordingly, this amendment meets the eligibility criteria for categorical exclusinn t.c: ier*i. in 10 CFR51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environment 61 impact statement or environmental assessment need be prepared in connection with the issuance of this amendment.

4.0 COWCLUSION The Commiscion made a proposed determination that the amendment involves no significant hazards consideration which was published in the Federal Register (54 FR 51261) on December 13, 1989 and consulted with the State of New Jersey. No public comments were received and the State of New Jersey did not have any comments.
l The staff has concluded, based on the considerations discussed above, l
l that:
(1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Commission's regulations and the issuance of this amendment will not be inimical.to the common defense and security nor to the health and safety of the public.
