4 Changes to Gompliance Method The following changes to the compliance method as documented in the OIP (Reference 1) are being made. These changes are being incorporated into Revision 1 of the OlP, which is being submitted under a separate letter. The changes do not impact compliance with Nuclear Energy Institute (NEl) 12-06.
The following discussion details three significant changes to the coping strategies planned for PNPP OlP, Revision 1:
o Change from 480 volts alternating current (Vac) to 4160 Vac FLEX power source o Change from Suppression Pool "Feed and Bleed" to Suppression Pool Closed Loop Cooling Change from portable pumps at the barge slip to portable pumps in the Emergency Service Water Pumphouse (ESWPH)
Chanqe from 480 Vac to 4160 Vac Alternate Power Source PNPP OlP, Revision 0, provided for the use of a 750 kilowatt (kW) 480 Vac diesel generator to provide power to 480 Vac Bus EF-2-8. Bus EF-2-B would then distribute 480 Vac power to critical loads via (1) Unit 1 divisional 480 Vac busses and (2) dedicated power supplies to new or existing 480 Vac manual transfer switches.
The planned PNPP OlP, Revision 1, provides forthe use of two 1.1 Megawatt (MWe) 4160 Vac turbine generators [similar equipment is to be used at the Regional Response Center(s) (RRCs)J to provide power to Unit 2 4160 Vac Bus EH-21. A distribution center (similar equipment is to be used at the RRCs) will be supplied by two 1.1 MWe 4160 Vac turbine generators (operating in parallel) and connect to Bus EH-21 through a permanently installed docking station and isolation breaker on the bus.
Bus TH-21 will be modified to allow Bus EH-21 to provide an alternate power source to the unit cross-tie, and thereby, the alternate preferred source to the Unit 1 Class 1E switch gear (Bus EH-21 will power the Unit 2 off-site source to Unit 1 Class 1E switch gear). Bus EH-21 is the normal power supplyto Bus EF-2-B via Bus EF-?-A (through its su pply tra nsformer).
PNPP OlP, Revision 0, provided for supplying the Unit 1 Class 1E switch gear and Bus EF-2-B (via Bus EF-2-A and its supply transformer) by connection of the 1.1 MWe 4160 Vac turbine generato(s) to the load via free air cables and ground trucks (Phase 3 Milestone Target Completion Date Activity Status (as of 7131114)

L-14-257 Page 4 of 11 strategy). Bus EF-2-B remains the alternate power to the Suppression Pool Clean Up (SPCU) and Alternate Decay Heat Removal (ADHR) pumps through manual bus transfer switches.
This change in strategy provides for:
o Increased electrical capacity o Reduction in actions to restore power to critical loads required for FLEX coping Provides sufficient power to supply motor driven pumps located in the ESWPH o Simplifies operator action required to re-establish cooling water flow Chanqe from Suppression Pool Feed and Bleed to Suppression Pool Closed Loop Coolinq PNPP OlP, Revision 0, provided for containment heat removal by use of Suppression Pool "Feed and Bleed." Suppression Pool "Feed and Bleed" was accomplished by thermal mass transfer between the Suppression Pool and a dedicated storage volume, with cool water make-up provided by FLEX pumps. The identified "Feed" source was lake water from either the ESW A or ESW B supply headers through hosed connections to either High Pressure Core Spray (HPCS) or Low Pressure Core Spray (LPCS) flush connections. ESW would have been supplied by fire trucks at the barge slip taking a suction on the lake and pumping into the ESW headers via installed dry hydrants and dedicated buried pipe. Suppression Pool "Bleed" was accomplished by use of the SPCU or the ADHR pump taking suction on the Unit 1 Suppression Pool and transferring this heated water to the Unit 2 Suppression Pool.
The planned PNPP OlP, Revision 1, provides forthe use of the SPCU orthe ADHR pump taking a suction on the Unit 1 Suppression Pool and transferring the water to the Residual Heat Removal (RHR) System via the Fuel Pool Cooling and Cleanup (FPCC) to RHR suction header. Water flows through the RHR System, bypassing the RHR pump through existing system piping, through the RHR Heat Exchangers back to either the Reactor Pressure Vessel (RPV) or the Suppression Pool.
Pumps in the ESWPH will take a suction on the ESWPH suction bay that is fed by one of two seismically qualified (fully robust) intake/discharge lines that normally provide water to the ESWPH and discharge into the ESW System between the ESW pump discharge check valve and the discharge strainer. The flow in the ESW System is aligned to provide cooling water to the RHR heat exchangers, with ESW System hose connections to provide various other loads as required.
Suppression Pool Closed Loop Cooling replaces the large RHR pump with smaller 480 Vac pumps (ADHR or SPCU pump) and operates the RHR in a modified Suppression Pool to Suppression Pool flow path.
Additionally, these 480 Vac pumps can also serve as a motor-driven high capacity vessel injection source from the Suppression Pool once the RPV pressure is reduced sufficiently.
L-14-257 Page5of11 Chanqe from Portable Pumps at the Barqe Slip to Portable Pumps in the ESWPH PNPP OlP, Revision 0, provided for the use of two fire trucks to be deployed to the barge slip area where they would be connected to installed dry hydrants and pump the discharge into the ESW System between the ESW pump discharge check valve and the discharge strainer via an installed dedicated buried pipe to the ESWPH. The flow in the ESW System was used to supply water to the Reactor Core lsolation Cooling (RCIC) pump suction, LPCS/HPCS for Suppression Pool "Feed," and the Spent Fuel Pool (SFP) Spray System.
The planned PNPP OlP, Revision 1, provides for the use of one of two motor-driven FLEX pumps (for pumping lake water) in the ESWPH, as previously discussed. The flow in the ESW System is used to supply water to the RCIC pump suction, RHR heat exchangers for Suppression Pool Closed Loop Cooling, and the SFP Emergency Makeup System (SFPEMS). The motor-driven FLEX pumps (either the "N" or "N+1")
are supplied by a repurposed supply line originally designed to supply the Unit 2 Division 1 ESW pump via a docking station in the ESWPH. The docking station is normally fed from an isolation breaker on Bus EH-21 and can supply either the N and N+1 lake water pumps.
The FLEX pumps will be stored and used in the ESWPH. During use, a set of suction lines will be attached and lowered into the ESWPH suction bay via the associated Unit 2 ESW pump pedestal (pumps will be stored in the area where the Unit 2 ESW pump discharge piping would have been installed). Three S-inch discharge hoses will be attached between the FLEX pump discharge and the ESW loop. Free air cables will connect the FLEX pump to the docking station (feed from Bus EH-21 ) to provide electrical power.
Core Cooling and Heat Removal High Pressure Injection As in PNPP OlP, Revision 0, RCIC will be used in Phase 1 and Phase 2 in the planned PNPP OlP, Revision 1. Provisions remain to supply the RCIC Pump with an alternate coolant source to address Suppression Pool temperature concerns.
The RCIC alternate suction connection was to be installed in the Condensate Storage Tank (CST) supply line; however, this modification has been moved to the RCIC pump room just prior to the RCIC pump suction. To support this, dry stand pipes are installed in the east and west sides of the Auxiliary Building. The dry stand pipes run from Auxiliary Building elevation (EL) 620'6" to the Auxiliary Building EL574'6" (568'6") with connection points on Auxiliary Building EL 599'6". ESW supply header modifications (hose connections) can also be used via the dry stand pipes.
L-14-257 Page6of11 Low Pressure Injection PNPP OlP, Revision 0, provided for lake water injection via LPCS or HPCS flush connection supplied from the ESW supply header connection point. This provision remains in the planned PNPP OlP, Revision 1. Use of dry stand pipes replaces the dedicated riser from the ESW supply header in PNPP OlP, Revision 0. The water source and flow paths are not altered, except as previously discussed with respect to access to the Ultimate Heat Sink.
The planned PNPP OlP, Revision 1, also provides for low pressure RPV injection via the SPCU or ADHR pumps.
RPV Pressure PNPP OlP, Revision 0, provided for installation of a single connection point to allow a portable compressor to supply both the Division 1 and Division 2 air system to provide for long term system makeup.
The planned PNPP OlP, Revision 1, deletes the installation of the single connection point. Both air systems provide a seven-d ay air source and only one air bank is needed to provide long term RPV pressure control. Both systems can be supplied by use of normal (robust) system connection points that do not require modification for use.
Containment Function The change in strategy from "Feed and Bleed" to Suppression Pool Closed Loop Cooling, as detailed above, provides for continued containment preservation. The ADHR modification detailed in PNPP OlP, Revision 0, provided for a single hose connection to be installed at the outlet of the ADHR pump. The planned PNPP OlP, Revision 1, provides for three hose connections to allow higher flow rates to the RHR System.
The planned PNPP OlP, Revision 1, also provides for three connection points on the FPCC to RHR suction header to allow the ADHR discharge hoses to be connected.
PNPP OIP Revision 0, previously provided only one hose connection on this piping.
Containment Inteqrity Control of hydrogen is not changed in the planned PNPP OlP, Revision 1; however, an alternate power scheme using portable generators is provided in the case that the two 1.1 MWe 4160 Vac turbine generators cannot supply power to the divisional busses.
Spent Fuel Coolino PNPP OlP, Revision 0, provided for a SFP Spray System to be installed and supplied from either ESW A or ESW B.
L-14-257 Page 7 of 11 The planned PNPP OlP, Revision 1, includes a new SFP Emergency Makeup System that provides the three required functions of remote fill, fill using hoses, and SFP spray.
The SFP Emergency Makeup System provides a dump line configuration with system flow controlled external to the SFP area (external to the Fuel Handling Building). Hose connection point(s) for use of hoses to directly fill the pool or supply portable spray nozzles are also provided. The SFP Emergency Makeup System supply remains unchanged.
Safety Support Function The planned PNPP OlP, Revision 1, provides for a modification to install a new manual transfer switch to supply Distribution Panel F1C08. This manual transfer switch will have alternate power from Bus EF-2-B similar to the SPCU and ADHR pump manual transfer switches. Power to Distribution Panel F1C08 provides for the use of various installed equipment to support FLEX activities.
Storage PNPP OlP, Revision 0, provided for storage of fire trucks in the Unit 2 Auxiliary Building and the Diesel Generator Building. Two diesel generators would be stored in a dedicated Unit 2 bay in the Diesel Generator Building. This storage would utilize all three Unit 2 diesel bays. A new FLEX Storage Building would be constructed to hold the N+1 equipment.
The planned PNPP OlP, Revision 1, provides for storage of FLEX equipment in a single Unit 2 bay of the Diesel Generator Building and the Unit 2 Auxiliary Building. These two areas are sufficient to store all of the identified FLEX equipment, except the portable FLEX pumps used for pumping lake water that will be stored in the ESWPH.
Construction of a new FLEX storage building is not required.
Modification to Security Features and Barqe Slip Area PNPP OlP, Revision 0, provided for modification to security features in the travel path of the fire truck down to the barge slip; regrading of the travel path and deployment area was also required.
The planned PNPP OlP, Revision 1, does not provide for the use of the barge slip area and, therefore, modifications to the security features in the travel path and barge slip a rea a re not req u ired.
Need for Relief/Relaxation and Basis for the Relief/Relaxation FENOC expects to comply with the order implementation date. Relief/relaxation is not required at this time.
