9.0 TEST METHOD 9.1 Initial Lineup:

Operations will align Unit 1 and 2 Primary and Secondary Systems per attached Enclosures to allow the running of nonload shed loads to Simulate Hot Shutdown loads. This includes running Emergency Feedwater (EFW) and High Pressure Injection (HPI) pumps in recirc. Unit 3 will also run simulated hot shutdown loads during tests described in sections 9.2 and 9.4

Operations will align Unit 3 primary and secondary systems to simulate an Engineered Safeguards (ES) channels 1 through 8 actuation during tests described in sections 9.6, 9.8, 9.10, and 9.12. This includes aligning the HPI and Low Pressure Injection (LPI) Systems so that full Emergency Core Cooling System (ECCS) injection will occur when ES is actuated and the Main Feeder Busses (MFB's) energized. Other ES components [Reactor Building Cooling Units (RBCU's), Penetration Room Ventilation (PRV) tans, Low Pressure Service Water (LPSW) pumps, Reactor Building Spray pumps] will also be aligned to run in the ES mode. Electric containment isolation valves will be initially aligned so that they must travel to their Safety Position when ES is actuated and the MFB's are re-energized. The Unit 3 secondary s stem will be aligned to allow the running of both Motor Driven Emergency Feedwater (MDEFW) pumps in recirc.

9.2 Block Loading Three Unit Loss Of Offsite Power (LOOP) Loads onto the Keowee Underground:

All three Oconee Units will be aligned to their respective startup transformers. Loads will be started on all three units (HPI pumps, MDEFW pumps, etc.) to simulate hot shutdown loads. Simultaneously, all three Unit's startup transformers will be deenergized and Keowee Emergency started from shutdown condition. After s 21 seconds all three Oconee Units will Load Shed. At a 31 seconds all Three Oconee Units will Block Load onto the Keowee Underground Unit. An Enclosure is provided with contingency actions in the event the transfer to the Keowee Underground fails.

9.3 Dead Bus Transfer to Startup Source (System Grid):

After loading onto the Keowee Underground, Dead Bus Transfers (one Oconee Unit at a time) will be performed to transfer back to the startup transformer. Enclosures are provided to recover essential loads after each Dead Bus transfer.

9.4 Block Loading Three Unit LOOP Loads onto the Keowee Overhead after Keowee Load Rejection and Switchyard (S.Y.) Isolation:

All Three Oconee Units will be aligned to their respective


startup transformers. Simulated hot shutdown loads will be started on each Oconee Unit. The Keowee Overhead unit will be started and placed on the System Grid at the Maximum permissible load. A S.Y. Isolation will be initiated which will result in a loss of power to each Oconee Unit; emergency start of both Keowee Unit's; and a load rejection of the Keowee Overhead Unit. All three Oconee Units will receive power from the Keowee Overhead unit through their respective startup transformer in a 20 seconds. An Enclosure is provided with contingency actions in the event the Keowee Overhead unit fails.

9.5 Synchronization of the Keowee Overhead Unit to the System Grid:

While sup plying all three Oconee Unit loads, the Keowee Overhead Unit will be synchronized back to the System Grid across PCB-8. This will connect all three Oconee Units to the System Grid. The S.Y. configuration will be restored to normal.

9.6 Block Loading One Unit LOCA and One Unit LOOP loads (large unscheduled load) onto the Keowee Underground simultaneously while accelerating (a 60% voltage and frequency):

All three Oconee Units will be aligned to their respective startup transformers. Unit 1 will have an ES channel placed in test to initiate LOCA-timing in Emergency Power Switching Logic (EPSL). Simultaneously, Unit 1 and Unit 3 will have their startup transformers de-energized and ES channels 1 through 8 will be actuated on Unit 3. Unit 1 with simulated hot shutdown loads and Unit 3 with simulated ES loads, will Block Load onto the Keowee Underground Unit in a 11 seconds. An enclosure is provided to terminate ECCS flow. An Enclosure is also provided with contingency actions in the event the transfer to the Keowee Underground fails.


Dead Bus Transfers (one Oconee Unit at a time) will be performed to transfer back to the startup transformers. nclosures are be provided to recover essential loads after each

dead bus transfer.

9.8 Block Loading one unit LOCA and one unit LOOP loads (large unscheduled load) onto the Keowee Underground simultaneously after Load Rejection (s20 seconds):

The same test sequence described in step 9.6 will be performed with the exception that the Keowee Underground unit will be placed on the System Grid at Maximum permissible load prior to de-energizing Unit 1 and Unit 3 startup transformers and actuating ES channels 1 through 8 on Unit 3.



After loading onto the Keowee Underground dead bus transfers (one Oconee Unit at a time) will be performed to transfer back to the startup transformers. Enclosures are provided to recover essential loads after each Dead Bus Transfer.

9.10 Block Loading Single Unit LOCA followed by Two Unit LOOP loads to the Keowee Underground after Keowee Load Rejection:

All three Oconee Units will be aligned to their respective startup transformers. The Keowee Underground Unit will be started and placed on the System Grid at Maximum permissible load. Simultaneously all three startup transformers will be deenergized and ES channels 1 through 8 will be actuated on Unit 3. Unit 3 will load onto the Keowee Underground (after load rejection) in a 20 seconds with simulated ES loads (including MDEFW pumps). Units 1 and 2 will block load on the Keowee Underground in a 31 seconds with simulated Hot S/D loads. Enclosures are provided for each Oconee Unit to restart essential loads (S.F. Cooling S.Y. Battery Feeders, CCW, etc.) and terminate ECCS flow (Unit 3) at the appropriate time. An Enclosure is also be provided with contingency actions in case the transfer to the Keowee Underground falls.

9.11 Dead Bus Transfer to the Startup Source (System Grid):

After loading onto the Keowee Underground, Dead Bus Transfers (one Oconee Unit at a time) will be performed to transfer back to the startup transformer. Enclosures are provided to recover essential loads after each Dead Bus transfer.

9.12 Block Loading Single Unit LOCA followed by Two Unit LOOP Loads onto the Lee Combustion Turbine (CT):

A Lee CT will be placed on the standby busses. All three Oconee Units will be aligned to their respective startup transformers. Simultaneously, all three startup transformers will be deenergized and ES channels 1 through 8 will be activated on Unit 3. Unit 3 will Block Load onto the Lee CT with LOCA loads in ; 11 seconds. Unit 1 and Unit 2 will Block Load onto the Lee CT with hot shutdown loads in a 31 seconds. An enclosure is provided to terminate ECCS flow on Unit 3. An Enclosure is also provided with contingency action in case the transfer to the Lee CT fails.

9.13 Dead Bus Transfer to the Startup Source (System Grid):

After loading onto the Lee CT, Dead Bus Transfers (one Oconee Unit at a time) will be performed to transfer back to the startup transformer. Enclosures are provided to recover essential loads after each dead bus transfer.
