Changes to Compliance Method The following identifies changes to Reference 3, as applicable, and the reason for each change. All changes meet applicable NEI 12-06 compliance methods.
Change 1 - "General Integrated Plan Elements" (1)
"Discussion of time constraints identified in Attachment 1A" (a)
Item (15): The vital de battery load shedding scheme has been revised to use Battery 1-3 (2-3) first and then Batteries 1-1 (2-1) and 1-2 (2-2) together after the first battery approaches depletion.
(b)
Item (20): The revised vital de battery load shedding scheme and associated revised load shed calculation results in Vital Battery 1-3 (2-3) providing power for at least 21 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br /> and Batteries 1-1 (2-1) and 1-2 (2-2) providing power for at least an additional 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br />.
The load shedding scheme was revised to ensure either wide range steam generator (SG) level or narrow range SG with auxiliary feedwater (AFW) flow indication is available at all times.
(2)
Updated reference documents 4 and 12 from Reference 1 for current document revisions used in calculations and evaluations.
Change 2 - "Maintain Core Cooling and Heat Removal Strategy" (1)
"Phase 2, Modifications": Updated description of the primary connection point on the motor-driven AFW pump discharge crosstie to reflect the current design of adding an isolation valve and a threaded connection point rather than a flanged connection.
PG&E Letter DCL-15-099 Enclosure Page 4 of 15 (2)
"Phase 3": Clarified that one train of cooling for each Unit would be repowered by a 4 kV generator set rather than a single generator.
(3)
"Phase 3, Strategy-Connections": Clarified that one train of cooling for each Unit would be repowered by a 4 kV generator set rather than a single generator.
Change 3- "Maintain RCS Inventory Control Strategy" (1)
"All Phases-Key reactor parameters": Clarified that the Reactor Vessel Level Instrumentation System (RVLIS) is a back up to pressurizer level as RVLIS will only be available when Vital Batteries 1-1 (2-1) and 1-2 (2-2) are in service together.
(2)
"Phase 2": Removed reference to the 480 volt (V) generator being prestaged in the radiological control area (RCA), as this equipment will be stored in the FLEX Storage Facilities. The storage location was changed during the detailed design of generator storage due to challenges related to permanent storage of the generator in the radiological controlled area.
(3)
"Phase 2": The 480 V generator will be staged at either the 115 ft elevation RCA bench area or the 85 ft elevation west of the turbine building near the turbine building machine shop to provide power to the Emergency Reactor Coolant Systems (ERCS) make-up pumps.
(4)
"Phase 2, Strategy-Equipment Storage-Pre-staging inside the RCS":
Removed reference to the 480 V generator, as this equipment will be stored in the Primary Beyond-Design-Basis (BOB) Storage Facility.
(5)
"Phase 2, Strategy-Equipment Storage": Inserted row for equipment storage in the Primary BOB Storage Facility:

accordance with NEI 12-06,
j Section 5.3.1.
PG&E Letter OCL-15-099 Enclosure Page 5 of 15 (6)
"Phase 2, Strategy-Equipment Storage-Secondary BOB Storage Facility": Removed reference to the backup ERCS make-up pump and associated high pressure hoses, as this backup equipment will be stored in the Primary BOB Storage Facility.
Change 4 - "Maintain Containment" (1)
"All Phases, Key containment parameters": Containment temperature was added as a key containment parameter. Containment temperature can be monitored from the control room using the indicator on the post-accident monitoring panels.
(2)
"Phase 3": Clarified that one train of cooling for each Unit would be repowered by a 4 kV generator set rather than a single generator Change 5 - "Maintain Spent Fuel Pool Cooling" (1)
"Phase 2, Strategy-Equipment Storage": Storage boxes are being installed on the 140 ft elevation of the fuel handling building next to each spent fuel pool (SFP). These storage boxes will be anchored to the floor within the seismically qualified building. Hoses, fittings, nozzles, and associated equipment required to be deployed early in the Maintain SFP Cooling strategy will be stored in the boxes.
(2)
"Phase 3": Clarified that one train of cooling, including a SFP cooling pump, for each Unit would be repowered by a 4 kV generator set rather than a single generator.
Change 6 - "Safety Functions Support" (1)
"Phase 1, Electrical": The revised vital de battery load shedding scheme and associated revised load shed calculation results in Vital Battery 1-3 (2-3) providing power for at least 21 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br /> and Batteries 1-1 (2-1) and 1-2 (2-2) providing power for at least an additional 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br />.
Change 7-Attachment 1A, "Sequence of Events Timeline" (1)
Action Item 20: Revised elapsed time, action, and time constraint for switching from Battery 1-3 (2-3) to Batteries 1-1 (2-1) and 1-2 (2-2) to align
PG&E Letter DCL-15-099 Enclosure Page 6 of 15 with the changes to the de battery load shedding scheme and timing as described in Change 1, Item 1 of this document.
(2)
Action Item 24: Elapsed time and time constraint to repower battery chargers to align with the changes to the de battery load shedding scheme and timing as described in Change 1, Item 1 of this document.
Change 8-OIP Attachment 2, "DCPP Units 1 and 2 Implementation Milestone Schedule" Refer to Section 3 of this Enclosure.

formerly Regional Response Center (RRC), local staging area, evaluation of access routes, and method of transportation to the site in the final compliance letter.
Confirmatory Item 3.2.1.B:
RCS cooling and heat removal, and RCS inventory control-The licensee provided information regarding the analysis from WCAP-17601 applicable to DCPP in response to NRC staff requests. The NRC staff is continuing to review this information to ensure the licensee sufficiently justifies the analysis being applied. Additional information may be needed to confirm appropriate use of the analysis.
Response: PG&E notes that the NRC Staff is continuing to review information regarding the analysis from WCAP-17601 applicable to OCPP in response to

Confirmatory Item 3.2.1.4.A:
The licensee used the Modular Accident Analysis Program (MAAP) code in petforming its ELAP analyses. Aspects of the MAAP code analyses, such as boundary conditions, nodalization, and the selection of code options for modeling key physical phenomena, were not discussed in the Integrated Plan. Provide an understanding of the above issues to assess the technical adequacy of the code and determining the code's range of applicability.
Response: PG&E will provide information on the MAAP code used in performing the Extended Loss of Alternating Current Power (ELAP) analysis to show the technical adequacy of the code and the code's range of applicability in the final compliance letter.
Confirmatory Item 32.1.6.A:
On pages 70 through 73 in the Integrated Plan, the licensee listed elapsed times and time constraints in different columns in Attachment 1A (sequence of events timeline).
The review determined that the times listed in the elapsed time column and the time constraint column often are the same and provide no margin between the elapsed time and the time constraint time. Provide clarification on how early a step must be begun to meet the time constraint, when the licensee actually expects to begin petforming the step, information on what margin exists for these critical actions, and whether the time can be reasonably met.
Response: PG&E will provide clarification on how early a step must be begun to meet the time constraint, when it is expected to begin performing the step, information on what margin exists for these critical actions, and whether the time can be reasonably met in the final compliance letter.

Communications-Confirm that upgrades to the site's communications systems have been completed.
Response: PG&E will confirm the completion of the upgrades to the site's communications systems in the final compliance letter.
Confirmatory Item 3.4.A:
PG&E Letter DCL-15-099 Enclosure Page 9 of 15 NEI 12-06, Section 12.2 lists minimum capabilities for offsite resources for which each Licensee should establish the availability. Discuss implementation of Guidelines 2 through 10 in NEI12-06, Section 12.2.
