LCR 87-06 Pcga 1 of 4 Description of Change This proposed amendment to the Hope Creek Generating Station Technical Specification requests a one time extension to the local leak rate testing intervals for certain primary containment isolation valves specified in Technical Specifications 4.4.3.2.2.a and 4.6.1.2.d (Attachment 3).

Additionally, this proposal requests, relief from Section XI of the ASME code per 10 CFR 50, 50.55a(g) and its requirements to leak rate test Category A valves not less than once every two years. Although the ASME code test interval is larger than Technical Specification 4.4.3.2.2 interval noted below, the Section XI interval will be exceeded if this request is granted.

A request for exemption from the requirements of 10CFR50, Appendix J, Section III.D.3 is being submitted under separate cover to support this LCR.

Justification for Chance Technical Specification 4.4.3.2.2.A requires local leak rate tests for Reactor Coolant System Pressure Isolation valves listed in Table 3.4.3.2-1 to be leak tested at least once per 18 months. Past NRC reviews for Hope Creek have allowed Type "C" gas tests at 18-month intervals to be performed in lieu of water tests to satisfy these requirements (NUREG 1048 Supplement 5 Section 3.9.6). In addition to satisfying 4.4.3.3.2.a requirements these tests would also satisfy the l

Type "C" test requirements for these valves per Section 4.6.1.2.d. An additional 25 percent may be added to the 18-month interval per Specification 4.0.2.a. The valves for which this relief is requested are listed in Attachment 1 and are identified by having an overdue date entered in the 4.4.3.2.2.a (18-month) column. It should be noted that these dates are 18 months plus 25 percent dates.

l Technical Specification 4.6.1.2.d requires local leak rate tests (Type C tests) on the primary containment isolation valves listed in Table 3.6.3-1 to be performed at intervals no greater than 24 months except for containment isolation valves in hydrostatically tested lines penetrating the primary containment, which shall be leak tested at least once per 18 months. The Commission's Regulations (10 CFR 50, Appendix J, Section III.D.3) require local leak test (Type C tests) to be performed during each reactor shutdown for refueling, but in no case at intervals greater than two years.

The end of the initial 18-month and 24-month testing intervals for some of the Hope Creek Generating Station containment isolation valves is approaching. Type C tests have been performed within the test interval for those valves that did not require plant shutdown for testing. However, in order to

LCR 87-06 Pcgn 2 of 4 satisfy the test interval requirements for 12 tests covering twenty-seven valves (see Attachment 1), it would be necessary to shut down the plant for approximately two weeksprior to the first refueling outage solely for this purpose.

A containment entry is required to test the valves that cannot be tested at power. Testing of these valves at power poses a personnel hazard due to ALARA considerations, high ambient temperatures existing within containment and entry into the inerted containment. Additional restraints to testing some of the valves at power include the need to drain the "A" and "B" RHR loops, as well as the "A" core spray loop. For specific descriptions by valve, refer to Attachment 2.

The requested license change is' temporary and became necessary as a result of delays in attaining full power operation common to initial startup activities.

The current schedule is for the first refueling outage to begin approximately February 1, 1988. Testing for these valves will be performed prior to startup from this outage.

A two week outage required to perform this testing prior to the refueling outage would result in a net increase in overall outage time and would subject the plant equipment and systems to the detrimental effects inherent in an additional shutdown and startup operation.

Therefore, PSE&G requests an extension of the Type C test interval and certain 18-month leak tests for the specified primary containment isolation valves listed in Table 3.6.3-1, Part A, B, and C that require the plant to be shutdown for testing. PSE&G also requests relief from ASME Section XI per Section 50.55a(g) for leak rate testing interval requirements for the applicable Category A valves (see Attachment 1). The proposed change as shown on enclosed Technical Specification pages 3/4 4-12 and 3/4 6-4 (Attachment 3) would extend the test interval for these valves into the first refueling outage.

Additionally, it is requested the requirements of Technical Specification Section 4.0.2 be waived for this one time license change. For additional information, see the associated Appendix J Exemption Request.

Significant Hazards Consideration Determination '

The Commission'had provided guidance concerning the application of standards in 10 CFR 50.92 for determining whether license amendments involve significant hazards consideration by providing certain examples which were published in Federal Register on April 6, l 1983 (48 FR 14870). One of the examples j (vi) of an action involving no significant hazards J

consideration is a change which may in some way reduce a safety margin, but where the results of the change are clearly within )

'all acceptable criteria. The foregoing requested _ change _and exemption fits this example. Postponing:the aforementioned local leak rate tests until.the end of.the first. refueling outage'would allow.for continued operation of the plant and would have little or no~effect_on containment integrity as l g discussed below. 1

-(1) The containment 1 isolation valves listed on Attachment 1 were all_ tested.successfully in late

, 1985. The_ total of the measured Type C. leakage

,~

rates for'these valves is not a significant j portion (4.9%) of the. allowable-leakage limit .( 0 .' 6 Ls). Deterioration in the overall. integrity of  ;

the containment penetration'is normally;a gradual process.

f NUREG/CR 4330, Review of Light Water Reactor.

2 Regulatory-requirements, has shown-that i

containment leakage is'a relatively. minor.

contributor to overall plant risk. In addition inherent BWR design features will maintain the offsite doses below 10CFR100 limits even with

leakage above current limits.

1 (2) The intent of the Technical-Specifications leak rate testing intervals for pressure isolation

valves and containment isolation valves is to 4

require testing of the isolation valves once every.

fuel cycle. A. normal reactor fuel. load is designed to provide an 18-month cycle with approximately 16 months of full power operations. .

Consequently, the primary containment-isolation. _

valves are normally exposed to 18 months of rated temperature conditions.between each Type C_ test.

Since the initial Type C tests-at the Hope Creek

, Generating Station, these valves.will have been I subjected to rated temperature _ conditions l approximately equal to one 18-month operating cycle by the first refueling outage. An extension ~

of the Type C test interval ~to the first refueling

outage is not unrealistic when the intent of the Type "C" test schedule specified by the Technical.

, Specifications and Appendix.J is considered.

! - a For these reasons, the proposed temporary amendment to'the Hope a Creek Operating License does not constitute'a significant

]

hazards consideration in thatiit would.not e 1. Involve a significant increase in the probability or

consequences of an accident previously' evaluated since.

i the extension of the surveillance intervals.is i

consistent with the intent of_the regulations, when

. considering the operating conditions to which the subject valves have been exposed; or

3 LCR 87-06 Pcg3 4 of 4.

2. Create the possibility of a new type of accident or a different kind of accident:from any accident previously analyzed in that current analyses assume certain values of containment leakager. therefore, new accident scenarios are not credible based upon scheduling of this testing alone; or
3. Involve a significant reduction in the margin of safety because, based on initial LLRT results, these valves have exhibited a high degree of leak tight reliability. Additionally, the valves'will be exposed to operating conditions consistent with those normally experienced between testing intervals.

The requested amendment concerns schedular relief for surveillance testing of a limited number of containment isolation valves and will not result in a significant change in the amounts or types of effluents that may be released offsite.

There will be no significant increase in individual or cumulative occupational radiation exposure as a result of the requested amendment which merely requests to delay testing.
