Pumose The purpose of this evaluation is to provide documentation for the data variable used in the referenced North Atlantic Engineenno Evaluations.

Dieunion PLG 0500 is used as the data source for the SSPSS 19 and subsequent updates.

PLG 0500 contains maintenance duration data for a variety of components based upon Allowed Outage Times (AOTs).

Data variable, ZMPNSD is the maintenance duration term for pumps with no LCO (i.e.

unlimited AOT). This variable represents data from a variety of plants and systems within those plant (Tableisis a listing from PLG 0500 for data variable, ZMPNSD. As can be seen from Table 5, the large number of systems represented in Table 6 provide a spectrum of maintenance duration's. 2 w A new maintenance variable (7g'^p) has been created to more accurately portray the expected maintenance duration of the PCC/SW pumps at Seabrook. This term was created by counting only the CC/SW durations listed in PLG variable, ZMPNSD. The data rnodule of Riskman 2.05 was used to convert the highlighted durations from Table 16 into the variable 2 ttP$WD ZMF 'CA This variable was saved to the Seabrook system analysis control model (SB \SYS96\) and used in subsequent quantification of the proposed PCC and SW Tech Spec changes. ,

Data variable, ZA'PL. ,hwas created to more accurately reflect the expected maintenance duration for the Seabrook PCC and SW pumps. This data variable was used in the system analysis quantifications in support of the proposed PCC and SW Tech Spec changes.

- Attachment C - SW System Results This section contains the details ~ of the SW system quantification for maintenance. Results are I

presented for the Baseline case, the New TS case, and the Sensitivity case, in the following tables:

Table C.1 Maintenance Alignment Definitions - These tables present the equation for '

BASECASE maintenance term in terms of dato Table C.2 Maintenance Alignment Definitions - variables. They also show the impact of NEW TS CASE the maintenance olignment, i.e. what Table C.3 Maintenance Alignment Definitions -- basic event is failed as o result of the SENSITIV'TY CASE maintenance.

Table CA Maintenance Alignment Contributions to - These tables present the maintenance System Unovoilobility - BASECASE - contribution to system unavallobility for -

Table C.5 Maintenance Alignment Contributions to _the 6 boundary conditions discussed in System Unovoilobility - NEW TS CASE the evoluotion. This shows the Table C.6 Maintenance Alignment Contributions to conditional failure, the frequency of System Unovoilobility - SENSITIVITY being in the olignment, the total unovallobility contribution, and the importance of that alignment.

Table C 7 Cause Table for SW1 (Normal Alignment) - These tables present the dominant cut BASECASE sets for SW), normal configuration with Toble C.8 Cause Table for SW1 (Normal Alignment)-_ the CT. The cut set basic events are NEWTS CASE defined in Attachment A. Note that the Toble C.9 Cause Table for SW1 (Normal Alignment)- cutsets in (brockets] ore common cause SENSITIVITY CASE terms.

Attachment E - Plant Model Results l This section contains the ranked list of core damage sequences for the three cases: Table E.1 (Base Case), Table E.2 (New TS Cose) and Table E.3 (Sensitivity Case). Each list contains the top 25 sequences, with the SW impacted sequences highlighted.

The highest ranked sequence involving SW failure is Sequence #3: loss of offsite power and failure of both trains of SW. This is assumed to result in unrecoverable failure of the diesel generators. As i discussed in the evoluotion, SW is quantified for the normally operating ocean SW pumps only. The standby SW and CT pumps would not auto start, and no credit is given for the operator manually _ l storting the pumps due to limited time for DG cooling. Because of this, this sequence is not impacted by the New TS Case or the Sensitivity case.

The relationship between split fractions, used in the sequences, and system results, given in i Attachment C, is explained in the following tables:

- Table E.4 Split Fraction Report - BASELINE TableE.5 Split Fraction Report - NEW TS CASE Table E.6 Split Fraction Report - SENSITIVITY CASE f t91935W DCC 014194

~ Attachment D -Initiating Event Results - Loss of One Train SW This section contains the dominant cutsets for the initiator loss of one train of SW, in Table D.1 (Base Cose), Table D.2 (New TS Case) and Table D.3 (Sensitivity Case)

The Base Case shows that the highest frequency cutset is failure of the operating SW pump while the standby pump is in maintenance (LSWMNT). Cutsets 2, 3,5, and 6 are normally open volves, common to the SW train, that are modeled to transfer closed. hese are not impacted by changes to the maintenance model. Cutsets 4 and 7 are failure of the operating SW pump with failure of -

the standby pump to stort or failure of the discharge MOV to open.

%e New TS Case increases the duration of maintenance for the standby pump (AMNTI),. which

]

impacts the first cutset. The second cutset is failure of the operating SW pump while the standby. ':

pump is in planned maintenance. !

1 The Sensitivity Case is dominated by the operating pump failing to continue to run for on operating d year. )
