Palo Verde Nuclear Generating Station (PVNGS)
Unit 3 Docket No~ *STN 50-53_0 Renewed Operating License No. NPF-74 License Conditions Regarding Emergency License Amendment Request to Extend D~esel Gen.erator 38 Completion Time Arizona Public Service Company submitted a risk-informed license amendment request (LAR) to extend the Palo.Verde Nuclear Generating Station (.PVNGS) Unit 3, Technical Specification (TS) required action 3.8.1.B.4 completion time from 21-days to 62-days in Reference 1 and responded to requests for additional information in Reference 2. The LAR is for the duration_of the repair and testing needed to re-establish operability of the Uni.t 3 train 'B' emergency diesel generator (3B DG) that experienced a failure on D~cember 15, 2016.
In Att_achment 3 of Reference 1, APS identified 31 formal regulatory commitments. The commitments include compensatory measures intended to provide adequate risk management as well as actions related to the control of station activities during the extended 3B DG technical specification completion time. In a telephone conference with the NRC staff on Wednesday, January 4, 2017, changes to Attachment 3 of Ref~rence 1 were discussed, which included deleting a.commitment and revising the wording and elevating three of these formal regulatory commitments to license conditions. The Enclosure 1 to this letter is an updated Attachment 3 of Reference 1, documenting the changes. Enclosure 2 is a copy of the proposed revision to Appendix D to the Unit 3 operating license.

- 12. APS has *provided three portable diesel generators to ensure the aQility to bring Unit 3 to.cold shutdown in the event of a LOOP during the extended time period that the Unit 3train 'B' DG is inoperable. The three portable diesel generators operate in parallel as
. a set. The result is that the three portable diesel generators are suffici~nt to enable a cold shutdown of Unit 3 in the event of a LOOP with a single failure during th~
extended time period while the Unit 3 train 'B' DG is inoperable. The three portable diesel.generators are deployed and physi.cally connected to the Unit 3 train '.B' 4.16 kV
_AC FLEX connection box for the duration of the extended DG completion time.
- 13. The portable DGs have been verified available and functional by the completion of a test run prior to the initial period bf extended allowable outage time.
- 14. A diesel-driven FLEX SG Makeup Pump is deployed to its FLEX pad at Unit 3 for the duration of the extended DG* completion time.
- 15. See License Condition 1 above.
- 16. Establish transient combustible and hot work exclusion zones by procedure and using barriers/signage in the following compartments, and conducting shiftly walk.downs of these zones by the Fire Marshal or his designee:
- a. Fire zones FCCOR2 (120' Corridor Building) and FCCOR2A (120' Corridor Riser
. Shaft)
- b. Fire zones FCTB04 (upper level only, non-class DC Equipment, [FCTB04-TRAN:l,])
- c.
Fire zone FC86A (train 'A' Seismic Gap, make part of train 'A' Electrical Protected Equipment)
- d. Fire zone FCTBlOO zone ZTlG (SW corner, south half of 100' Turbine between columns TA and TC)
- 17. An additio.nal dedicated auxiliary operator will be added to each shift to implement the auxiliary feedwater cross-tie.
- 18. A continuous fire watch with a fire extinguisher and training to utilize the extinguisher will be posted in fire zone FCCOR2 (120' Corridor Building).
- 19. See License Condition 2 above.
- 20. Component testing or maintenance of safety systems and important nonsafety equipment in the off-site power systems that can increase the likelihood of a plant
. transient (unit trip) or LOOP will be avoided.
- 21. Discretionary work will be prohibited in the SRP switchyard during the extended Unit 3 train 'B' DG TS 3.8.1 Condition B required action completion time.
2 Updated Attachment 3 of December 30, 2016, APS License Amendment Request ATIACHMENT 3 License Conditions and Commitments
- 22. TS required systems, subsystems, trains, components, and devices. that depend on the remaining power sources will be verified to be operable and positive measures will be
, provided to preclude discretionary testing or maintenance activities on these systems, subsystems, trains, components, and devices.
- 23. Steam-driven emergency feed water pump will be controlled as protected equipment.
- 24. Deleted.
- 25. Availability of the portable DGs will be verified once per shift.
- 26. Approval of transient combustibles and hot work in Unit 3 will be controlled by the outage control center (OCC).
- 27. There will be an OCC position responsible for oversight and monitoring of the compensatory measures.and the actions described in this attachment.
- 28. See License Condition 3 above.
- 29. An auxiliary operator (AO) on each shift will be dedicated to perform pre~start checks of the portable generators each shift. This dedicated AO will perform the emergency start of the portable generators when directed and monitor their operation. The dedicated AO will have no other assigned duties during the extended completion time.
. 30. In the event of a reactor trip with a loss of off-site power, the Area 4 (Control Building)
AO, will perform the required electrical system alignments, as directed by the control room, to restore power to the 'B' train Class 1 E 4.16 kV bus using the portable generators, in accordance with station procedures.
3L In the event of a reactor trip with a loss of off-site power; one of the on-shift reactor.
operators will be assigned to perform and direct actions to restore power to the 'B' train Class 1 E 4.i6 kV bus using the portable generators. During the event, this reactor operator will not be assigned other duties until completion of power restoration.

Enclo.sure 2 Proposed Revision to Appendix D to PVNGS U,nit 3 Operating License.
Amendment Number Additional Conditions 200
- 1. The following equipment will be protected by signage/chains for the duration of the extended completion time to prevent inadvertent impact from walkdowns, inspections, maintenance and potential for transient combustible fires:
I
- a. Both SBOGs
- b. Unit 3 train 'A' DG Implementation Date The amendment shall be implemented prior to the expiration of the 21 day Technical Specification Completion Time, or January 5, 2017, at 3:56 AM Mountain.
- c. Unit 3 train 'A' Engineered Safety Features Time.
(ESP) Switchgear, DC equipment and DC Battery Rooms
- d. Three AC portable diesel generators deployed at Unit 3 and theirconnections to the train 'B' FLEX 4.16 kV AC connection box
- e. Diesel-driven FLEX SG Makeup Pump deployed at Unit.3
- f.
Turbine driven auxiliary feedwater pump
- g: Fire pumps, diesel an:d electric If any of the protected equipment identified above becomes unavailable; APS will enter MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for Unit 3. If restoration is completed within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> this action is not required.
- 2. The system load dispatcher will be contacted once per day to ensure no significant grid perturbations (high grid loaqing unable to withstand a single contingency of line or generation outage) are expected during the extended allowed outage time.
If at any time AP~ is notified by the system load dispatcher that a condition in the grid could result in the loss of all power to the switchyard, APS will enter MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> for Unit 3. If the condition is resolved within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> this action is not required.
- 3. In case APS determines prior to expiration of the extended completion time, a common failure mode does exist, then APS will shut down Unit 3.
