1 Attachment C - PCC System Results This section contains the details of the PCC system quantification for maintenance, Results are presented for the Baseline case, the New TS case, and the Sensitivity case #1, in the following tables: | |||
Table C.1 Maintenance Alignment Definitions - BASE These tables present the equation for CASE the molntenance olignment in terms of Table C.2 Maintenance Alignment Definitions - dato vorlobles. They also show the NEW TS CASE impact of the molntenance alignment, Table C.3 Maintenance Alignment Definitions - i.e. what basic event is assumed failed SENSITIVITY CASE #1 as a result of the maintenance. | |||
Table C.4 Maintenance Alignment Contributions to These tables present the maintenance - | |||
System Unavailability - BASE CASE contribution to system unavailability for Table C.5 Maintenance Alignment Contributions to the 3 boundary conditions discussed in System Unavoitability - NEW TS CASE the evoluotion. This shows the Table C.6 Maintenance Alignment Contributions to conditional failure, the frequency of System Unovoitability . SENSITIVITY #1 being in the alignment, the total unavailability contribution, and the importance of that alignment. | |||
Table C.7 Cause Table for PCC1 (Normal Alignment)- These tables present the dominant cut . l BASE CASE sets for PCC1, normal configuration. | |||
Table C.8 Cause Table for PCC) (Normal Alignment)- The cut set basic events are defined in NEW TS CASE Attachment A. Note that the cutsets in Table C.9 Cause Table for PCC1 (Normal Alignment) - [ brockets] are common cause terms. | |||

Attachment D -Initiating Event Results - Loss of One Train PCC l This section contains the dominant cutsets for the initiator loss of one train of PCC, for the ! | |||
following cases: ' | |||
Table D.1 Cause Table for LIPCC - BASE CASE, Table D.2 Cause Table for LlPCC - NEW TS CASE, and Table D.3 Cause Table for LIPCC - SENSITIVIT/ CASE #1 The Base Case shows that the highest frequency cutset is common cause failure of the temperature transmitters that trip both PCC pumps. This cutset is not impacted by the maintenance changes. | |||
The next cutset is failure of the operating PCC pump while the standby pump is in maintenance (MAINTA). Cutsets 3 through 7 are failures of other components that are not impacted by changes to the maintenance model. Cutset 8 is failure of the operating PCC pump with failure of the standby pump to stort. | |||
The New TS Case increases the duration of maintenance for the standby pump (MAINTA), which impacts the first cutset. The third cutset is failure of the operating PCC pump while the standby pump is in planned maintenance (PLMNTA). | |||
The Sensitivity Case #1 is dominated by the operating pump failing to continue to run for on operating year. | |||

They also show the NEW TS CASE impact of the molntenance alignment, Table C.3 Maintenance Alignment Definitions - i.e. what basic event is assumed failed SENSITIVITY CASE #1 as a result of the maintenance. Table C.4 Maintenance Alignment Contributions to These tables present the maintenance - System Unavailability - BASE CASE contribution to system unavailability for Table C.5 Maintenance Alignment Contributions to the 3 boundary conditions discussed in System Unavoitability - NEW TS CASE the evoluotion. This shows the Table C.6 Maintenance Alignment Contributions to conditional failure, the frequency of System Unovoitability . SENSITIVITY #1 being in the alignment, the total unavailability contribution, and the importance of that alignment. Table C.7 Cause Table for PCC1 (Normal Alignment)- These tables present the dominant cut . l BASE CASE sets for PCC1, normal configuration. Table C.8 Cause Table for PCC) (Normal Alignment)- The cut set basic events are defined in NEW TS CASE Attachment A. Note that the cutsets in Table C.9 Cause Table for PCC1 (Normal Alignment) - [ brockets] are common cause terms. SENSITIVITY CASE #1

l l Attachment D -Initiating Event Results - Loss of One Train PCC l This section contains the dominant cutsets for the initiator loss of one train of PCC, for the ! following cases: ' Table D.1 Cause Table for LIPCC - BASE CASE, Table D.2 Cause Table for LlPCC - NEW TS CASE, and Table D.3 Cause Table for LIPCC - SENSITIVIT/ CASE #1 The Base Case shows that the highest frequency cutset is common cause failure of the temperature transmitters that trip both PCC pumps. This cutset is not impacted by the maintenance changes. The next cutset is failure of the operating PCC pump while the standby pump is in maintenance (MAINTA). Cutsets 3 through 7 are failures of other components that are not impacted by changes to the maintenance model. Cutset 8 is failure of the operating PCC pump with failure of the standby pump to stort. The New TS Case increases the duration of maintenance for the standby pump (MAINTA), which impacts the first cutset. The third cutset is failure of the operating PCC pump while the standby pump is in planned maintenance (PLMNTA). The Sensitivity Case #1 is dominated by the operating pump failing to continue to run for on operating year. I J l ec_nnoc e2am j l
