.J r' BEFORE THE UNITED STATES NUCLEAR REGULATORY COMMISSION 6
in the Matter of )
NEW YORK POWER AUTHORITY ) Docket No. 50-333 James A. FitzPatrick Nuclear Power Plant )
APPLICATION FOR AMENDMENT TO OPERATING LICENSEi The New York Power Authority requests an amendment to the Technical Specifications contained in Appendix A to Facility Operating License DPR-59 for the James A. FitzPatrick Nuclear Power Plant. This application is filed in accordance with Section 10 CFR 50.90 of the Nuclear Regulatory Commission's regulations.
This application for an amendment to the James A. FitzPatrick Technical Specifications (TS) proposes changes to TS Table 3.2 2, " Core and Containment Cooling System initiation and Control Instrumentation Operability Requirements." The proposed changes will revise allowed outage times (AOis) for 4kV Emergency Bus Undervoltage Trip Functions. The AOTs for these trip functions were extended by Amendment 227; however, the AOT extensions for these trip functions were not consistent with the requirements of Standard Technical Specifications (STS), NUREG-1433, and differed from the recommendations in the associated Licensing Topical Report.
. Additional changes are proposed to TS Table 3.2-2 and to TS Table 4.2-2, " Core and Containment Cooling System Instrumentation Test and Calibration Requirements." These changes will: (1) replace the generic actions for inoperable instrument channels with function-specific actions, (2) replace the generic test AOT with function-specific test AOTs, and (3) relocate selected trip functions from the TS to an Authority controlled document. This will ensure consistency with STS, simplify the use of TS, and streamline STS conversion by minimizing the differences between current TS and STS. The changes will also enhance safety by ensuring that an inoperable instrument channel is not placed in the tripped condition when this condition is not a safe state for the channel.
Attachment 111 contains the proposed new TS pages and Attachment IV is the Safety Evaluation for the proposed changes. A markup of the affected TS pages is included as Attachment V. Attachment Vi lists the commitment contained in this submittal.

.. g Attachment 1 Page 1 of 1 The following was requested in Reference 1:
"Specify with examples to support the following:
"rteplace the generic actions for inoperable Instrument channels with function specific actions."
Refer to the sections of the submittel and page numbers. Be specific to show how this was accomplished.
" Replace the generic test AOT with function specific AOTs."
Refer to the sections of the submittel and page numbers. Be specific to show how this was accomplished. CIsrlfy how these are consistent with STS."
Response
The current Technical Specifications (TS) have a generic action statement and a generic test allowed outage times (AOTs) applied to 31 different trip functions for " Core and Containment Cooling System Initiation and ControlInstrument channels"(table 3.2-2). The generic statements (note 1 and 2 for Table 3.2-2, pages 66 - 70) were not appropriate in all cases for some of the instrumentation as stated in the original submittal. The proposed changes to replace the generic actions and test AOT statements for all trip functions with specific action and test AOTs for each instrument trip function facilitate correcting the inappropriate actions for the specific instrument trip functions. These specific r.ctions for each instrument are consistent with improved Standard Technical Specifications (ST3), NUREG 1433, Revision 1.-
To demonstrate how this was accomplished specific trip function item 1 " Reactor Low-Low water Level" of table 3.2 2 (page 66) will be used as an example:
The generic action statements and test AOT Notes 1 and 2, respectively, are to be removed from table 3.2-2, pages 66-70 of current TS.
- Specific action statement and test AOT notes 1 and 11, respectively, are to be added to specific function item 1 " Reactor Low-Low Water Level". Notes 1 and 11 are located on proposed TS pages 70 and 71b.
The new function specific action statement note 1 is consistent with STS table 3.3.5.1-1 (HPCI) function 3a (Reactor Vessel Water Level - Low Low, Level 2) and STS table 3.3.5.2-1 (RCIC) function 1 (Reactor Vessel Water Level - Low Low, Level 2) to declare the system inoperable within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> if initiation capability is lost (Required Action B.2) and to place the channel in trip within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (Required Action B.3). New function specific test AOT note 11 is consistent with STS surveillance requirements 3.3.5.1 (HPCI) and 3.3.5.2 (RCIC) which allow the associated conditions and required actions to be delayed up to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> provided the associated function maintains initiation capability.

This note was used to identify single channel trip systems, and was necessary for interpretation of the generic test AOT. Since the generic test AOT has been replaced with function specific test AOTs, this note is no longer required.
Added function specific action Note 2 to the second column for table item 10 on page 67. Note 2 (page 70) provides actions for one or more inoperable instrument charnels. The existing generic actions provide a 6-hour repair AOT for multipie inoperable instrument channels, provided function capability is maintained. Only *wo channels of reactor low pressure are provided for this trip function; therefore functior capability is not maintained when more than one channel is inoperable and thus, the 6-hour repair AOT is not applicable to this trip function. The function-specific actions require the supported feature be declared inoperable within one hour from discovery of loss of initiation capability for feabres in both divisions (i.e., both LPCI subsystems).
This is consistent with STS requ,rements for similar trip functions. This trip function is not included in the STS and will be evaluated for possible relocation during STS conversion.

Deleted table items 16,17,18,19,20,21, and 25 from pages 68 and 69. The bus power monitors provide an alarm when they sense a loss of power on their respective logic bus. The differential pressure function provides an alarm when a break is detected in the core spray sparger. The valve position function provides an alarm when a locked closed valve is not fully closed. These trip functions are deleted to be consistent with STS, and because they do not satisfy the 10 CFR 50.36 criteria for inclusion in the TS. These trip functions provide only control room annunciation upon detection of abnormal conditions for the associated ECCS. These functions are not relied upon for detection or mitigation of any transient or accident, are not relied upon to detect degradation of the reactor coolant pressure boundary, and are not significant to public health and safety, in addition, the existing TS requirements for these trip functions specify that an inoperable channel be tripped upon expiration of the repair AOT. This action would serve no purpose other than to cause annunciation in the control roo n.
Upon approval of this amendment application, the operability requirements for these functions will be relocated to en Authority controlled document. In addition, the actions for an inoperable instrument channel will be revised to require that the associated parameter be monitored at least every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. Any future change to the design, surveillance or operability requirements of these trip functions will be controlled under 10 CFR 50.59. This commitment is listed in Attachment IV of Reference 2.

Note 9 (page 71a) provides revised actions for one or more inoperable instrument channels. The revised actions delete the requirement to trip one trip system within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for multiple instrument channel failures. The revised actions also provide the option to align suction for the affected system to the suppression pool, rather than tripping an inoperable instrument channel or declaring the affected system inoperable. The revised actions are consistent with STS. Reference STS Table 3.3.5.1 1, Functions 3d and 3e; and Table 3.3.5.2-1, Function 3.
Added function-specific test AOT Note 11 to the second column for the renumbered trip functions. Note 11 (page 71b) Note 11 provides the test / o ' that is consistent with existing TS and STS. Reference STS Surveillance Requirements 3.3.5.1 and 3.3.5.2, Note 2.

Renumbered as table items 19,20,21,22, and 23 on page 69.
Deleted Note 9 from the second column for the renumbered trip functions. This note is no longer required for interpretation of the TS.
Added function specific action Note 10 to the second column for the renumbered trip functions. Note 10 (page 71b) provides revised actions for one or more inoperable instrument channels. The revised actions require an iaoperable instrument channel be placed in trip within one hour, or the affected EDG System be declared inoperab'e, The revised actions are consistent with STS. Reference STS Section 3.3.8.1.
The changes described above delete any allowance for a test AOT for the 4kV Emergency Bus Undervoltage Trip Functions. This differs from STS in that the STS allow a 2-hour test AOT for these functions, provided EDG initiation capability is maintained. The current surveillance requirements for the FitzPatrick undervoltage trip functions consist of a once-per-18-month functional test and calibration. These functional tests and calibrations typically require more than 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to complete.
Therefore, based on the frequency and duration of surveillance, the 2-hour test AOT does not provide any significant operational benefit. During STS conversion, the surveillance requirements for these trip functions will be evaluated and thus, the 2-hour test AOT may be proposed at that time. I
