REQUEST FOR AME vfENT TO OPERATING LICENSE GARDING TECHNICAL SPECIFICATION RESPONSE TIME TESTING Attachment 3 Page 1 of 3 I NIFICANT HAZARD SIDERATION In accordance with 10CFR50.91, a licensee must provide to the staff analysis of a proposed amendment to the operating license using the standards in 10CFR50.92 concerning the issue of.

no significant hazards consideration. The Supply System has evaluated the proposed amendment to the operating license and determined that it does not involve a significant hazards consideration.

The following evaluation is provided for the three categories of no significant hazards consideration standards:

Operation of WNP-2 in accordance with the proposed amendment will not involve a significant increase in the probability or consequences of an accident previously evaluated.

The purpose of the proposed license change is to eliminate response time testing requirements for selected instrumentation in the Reactor Protection System (RPS), Primary Containment Isolation Actuation, and Emergency Core Cooling System (ECCS). However, because of the continued application of other existing Technical Specification required testing such as channel calibrations, channel checks, channel functional tests, and logic system functional tests, the response time of these systems will be maintained within the limits assumed in plant safety analyses and required for successful mitigation of an initiating event. The proposed license change does not affect the capability of the associated systems to perform their intended functions within the required response time, nor do the proposed changes affect the operation of any equipment.

The Reference 1 evaluation demonstrates that response time testing is redundant to the other Technical Specification required testing listed in the preceding paragraph. This evaluation was reviewed and approved by the staff. These other tests, in conjunction with actions taken in response to NRC Bulletin 90-01, "Loss of Fill-Oil in Transmitters Manufactured by Rosemount," and Supplement 1, are sufficient to identify failure modes or degradations in instrument response time and ensure operation of the associated systems within acceptable limits.

Furthermore, all known failure modes that are detected by response time testing are also detected by other Technical Specification tests.

In addition, two categories of components were included in this change in testing methodology which were not identified in the table of components in Reference 1. These components are used within the logic circuits addressed in Reference 1. These components were inadvertently omitted from lists provided to General Electric in support of preparation of the Reference 1 tables.

.pC..; s

-.'EQUEST FOR AMEN ~ ENT TO OPERATING LICENSE GARDING TECHNICAL

'-'r, v" SPECIFICATION RESPONSE TIME TESTING Attachment 3 Page 2 of 3 These components have been reviewed for similarity to the items contained within the Reference 1 component tables and have been found to be similar to other equipment referenced in the table.

These components are also subject to periodic functional testing by CFTs and LSFTs. The Supply System verified instrument response of these components at an appropriate interval using the alternate methodology for instrument verification described in Reference 1.

The two categories of components referenced above which are not included in the Reference 1 component list have no postulated functions or affects which may cause an accident. These devices are tested periodically to verify functionality. Sufficient time margin is available in the station accident analysis to account for the amount of time delay allowed by the Reference 1 methodology.

, For the changes dealing with moving the surveillance requirement for ECCS RESPONSE TIME testing from the Instrumentation section to the System section of the Technical Specifications, no change in testing requirements (other than the elimination of the instrument loops implemented as part of the Reference 1 change) has been introduced. The relaxation in Applicability does not increase the probability or the consequences of an accident previously evaluated, since there are no design basis events which credit ECCS during MODES 4 and 5.

Therefore, the proposed amendment request does not involve a significant increase in the probability or consequences of an accident previously evaluated.

Operation of WNP-2 in accordance with the proposed amendment will not create the possibility of a new or different kind of accident from any accident previously evaluated.

The proposed amendment only applies to the testing requirement for the components identified and does not result in any physical change to these or other components or their operation. The changes do not affect the capability of the associated systems to perform their intended function within the acceptable limits assumed in plant safety analyses and required for successful mitigation of an initiating event. The proposed amendment does not change the way in which any plant systems are operated or create the possibility of a new or different kind of accident.

As, a result, no new failure modes are introduced.

The two categories of components referenced above which are not included in the Reference 1 component list have no postulated functions or affects which may contribute to the initiation of an accident.

i The proposed amendment represents reliance on a different, and previously staff approved, method to verify selected components remain fully functional and will not create the possibility of a new or different kind of accident from any accident previously evaluated.

REQUEST FOR AMENDMENTTO OPERATING LICENSE LARDING TECHNICAL SPECIFICATION RESPONSE TIME TESTING Page 3 of 3 Operation of WNP-2 in accordance with the proposed amendment change will not involve a significant reduction in the margin of safety.

The current response times are based on the maximum allowable values assumed in the plant safety analyses. These analyses conservatively establish the margin of safety. As described above, the reliance on an alternate methodology for instrument response verification (Reference

1) will not affect the capability of the associated systems to perform their intended function within the allowed response time used as the basis for the plant safety analyses.

The two categories of components referenced above which are not included in the Reference 1 component list are qualitatively tested periodically by channel calibrations, CFTs and LSFTs.

This testing verifies the proper function and response of these components. Adequate time margins have been verified to be available within the applicable analyses which enable qualitative assessment of the proper performance of these devices.

Plant and system response to an initiating event will remain in compliance with the assumptions of the safety analyses, and therefore the margin of safety is not affected.

October, 1995.

ENVIR NMENTALCONSIDERATIONS Based on the above evaluation, this proposed change to the license does not result in a significant hazards considerations. In addition, the proposed change does not create a potential for a

,significant change in the types, or a significant increase in the amount of any effluent that may be released offsite, nor does the change involve a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the amendment meets the eligibility criteria for a categorical exclusion as set forth in 10CFR51.22(c)(9). Therefore, in accordance with 10CFR51.22(b), an environmental assessment of this amendment is not required.
