PROBABILISTIC RISK ASSESSMENT REPORT SONGS 2/3 Auxiliary Feedwater Pump Surveillance Test Frequency Evaluation June 26, 2002 REPORT PRA-02-04 Prepared by: Reviewed by: Approved by: (M. P. Carr) (P. Moieni) (M. P. Carr)

PRA-02-04 OBJECTIVE The purpose of this analysis is to determine the increase in core damage frequency (CDF) and large early release frequency (LERF) due to changing the testing of the auxiliary feedwater pumps requirement from a 31 days staggered to a quarterly frequency. BACKGROUND The current Units 2 and 3 Technical Specifications require testing the three auxiliary feedwater (AFW) pumps on a 31 day staggered test basis, which results in a requirement to test each pump quarterly. The current surveillance frequency of the turbine-driven AFW pumps (S21305MP140 and S31305MP140) at SONGS Units 2 and 3 is monthly based on administrative controls. Changing the requirement to test these three pumps on a quarterly versus a 31-day staggered basis would have the following impact:

1. The turbine-driven AFW pump would be tested quarterly instead of monthly.

2. The timing of the testing of each of the three pumps would be independent of each other.

3. The testing of the motor-driven AFW pumps (P504 and P141) would remain on a quarterly basis.

APPROACH A rigorous evaluation of the impact due to changing the surveillance frequency of the turbine-driven (TD) AFW pumps from monthly to quarterly and all three pumps from a 31-day staggered basis to a quarterly basis would employ a time-dependent risk analysis code such as FRANTIC or SOCRATES. Due to the low number of AFW pump failures in the recent years, development of the Weibull parameters with any certainty is not possible. Another method of evaluating a change in AFW pump surveillance frequency is to conservatively estimate the degradation in reliability due to reduced testing of the TD AFW pump and the increase in the exposure to having an undiscovered common-cause failure of the motor-driven AFW pumps. Together, these increases will be quantified in terms of core damage and large, early release risk and compared against the acceptance criteria in NRC Regulatory Guide 1.174 (Reference 4). 2 of 8

PRA-02-04 ANALYSIS To quantify the increase in core damage and large, early release risk associated with testing all three AFW pumps on a quarterly basis versus a 31-day basis, the following steps will be performed: Step 1. Calculate the baseline risk (CDFBaseline and LERFeaseline)assuming default average maintenance unavailabilities; Step 2. Calculate the new TD AFW pump failure rates due to changing the testing frequency from monthly to quarterly; Step 3. Calculate the new motor-driven AFW pump failure rates due to changing the testing frequency from a 31-day staggered basis to quarterly; Step 4. Input these new values into the Safety Monitor database and calculate the total risk (CDFmWorly and LERFAwQtrly)due to the testing frequency change; Step 5. Subtract the baseline risk from the total risk to obtain the increase in core damage and large, early release risk. These increases in risk values will then be compared to the acceptance criteria delineated in Regulatory Guide 1.174. Step 1: Baseline Risk Calculation The baseline core damage frequency and large, early release frequency are calculated using the SONGS 2/3 Safety Monitor assuming the following:

Mode 1 Operations
Internal and External Initiating Events included
Average component maintenance unavailabilities included
Single CCW/SWC train operation (P025(A), P112 running)
No Environment/Test Factors in Effect The baseline core damage frequency (CDF) and large, early release frequency (LERF) values resulted:

CDFBaseline = 4.1OE-05/yr LERFaseline = 1.41E-06/yr 3 of 8

PRA-02-04 Step 2: Increased TD AFW Pump Failure Rate The probability that a standby active component will fail when demanded during an accident is the sum of two failure modes: 1) test-induced failures; or 2) "standby" stresses (i.e., stresses that are present while the component is in standby, such as corrosion, dirt, and lack of lubrication). These failure modes manifest themselves in the number of demand failures per number of demands. The standby stress component of the failure probability is also known as the component's average "unavailability" and is calculated using the following equation: q = 1/2XT

where, q = the component's average unavailability X = the component's failure rate (assumed constant) while in standby, and T = the time interval between surveillance tests The average unavailability of the TD AFW pump, calculated by using the above equation, reflects the potential vulnerability of the component to "standby" stresses.

Such vulnerability increases with time between operability tests assuming corrective action is taken to restore the failed component identified by the test. Thus, the risk impact of extending the surveillance frequency is reflected by the increased unavailability due to the increase of the interval between surveillance tests. In other words, it is assumed that the failure rates associated with the TD AFW pump could increase up to a factor equal to the proposed increase in surveillance test interval. In this case increasing the testing frequency from monthly to quarterly would increase the TD AFW pump failure to start and failure to run failure rates by a factor of three(3) as follows: Basic Event ID Basic Event Description Default Revised V alu e V a lu e L-TP140-1DR TD AFW Pump FT Run 24 hrs 8.66E-3 2.60E-2 L-TP140-8HR TD AW Pump FT Run 8 hrs 2.89E-3 8.67E-3 L-TP14ONR-S TD AW Pump FT Start (Non-recoverable) 3.73E-3 1.12E-2 IL-TP14ORR-S TD AFW Pump FT Start (Recoverable) 7.47E-3 2.24E-2 This approach is somewhat conservative since the failure probability (number of actual failures/demand) is made up of failures from both "standby" stresses and test-induced failures. 4 of 8

PRA-02 -04 Step 3: Increased MD AFW Pump Failure Rates Since the motor-driven (MD) AFW pumps are currently tested every three months, the independent MD AFW pump failure rates will remain unchanged for the purpose-of this analysis.

However, changing the testing of the MD AFW pumps from a31-day staggered basis to a quarterly basis will-impact the MD AFW pump common-cause failure (CCF) rate values since-there is an increased time of exposure for a common cause failure mode to go unidentified.

The current MD AFW CCF rates in the.-SONGS 2/3 PRA model are calculated assuming that these pumps are tested on a staggered basis. These CCF rates require revision to reflect testing on a non-staggered basis. NUREG/CR-5485, "Guidelines on Modeling Common-Cause Failures in PRA," (Reference 1), provides guidance on the treatment of common cause failures based on staggered testing and non-staggered testing. Per Table 5-5 of Reference 1, for a -out-of-2 component system, the common-cause failure based on non-staggered testing is calculated as follows: CCFNOn-staggered = [2C2/ at] Qt Per Table 5-5 of Reference 1, for a 1-out-of-2 component system, the common-cause failure based on staggered testing is calculated as follows: CCFstaggered = a2Qt Where a2 = fraction of the total frequency of failure events that occur in the system and involve the failure of 2 components due to common cause. Qt = the total failure frequency of each component due to all independent and common cause events and at = a + 2a 2 (Eqn 5.9, Ref. 1) Therefore, the relationship, R, between CCF quantification assuming non-staggered testing and CCF quantification assuming staggered testing is 5 of 8

PRA-02-04 R CCFNon-staggered = 2a 2 / ( 1 +2ac 2 ) ] Qt CCFstaggered a2Qt Which reduces to R = 2 (aj+2ct2 ) The above alpha factors, l and 2, obtained from Table 9-19, "Alpha Factor Distributions, PWR Auxiliary Feedwater Pumps - All Pump Types, Fail to Start" in Reference 2, NUREG/CR-S497, "'Common-Cause Failure Parameter Estimations" are 0.8993 and 0.111, respectively. Therefore, the CCF relationship between non-staggered and staggered testing for the failure to start failure mode is Rstart 2 = 1.80 (0.8893 + 2*0.111) Similarly, for the failure to run failure mode, a and a2, obtained from Table 9-22, "Alpha Factor Distributions, PWR Auxiliary Feedwater Pumps - All Pump Types, Fail to Run" in Reference 2, are 0.9812 and 1.88E-2, respectively. Therefore, the CCF relationship between non-staggered and staggered testing for the failure to run failure mode is RRUn = 2 1.96 (0.9812 + 2*1.88E-2) The common-cause failure basic events associated with the MD AFW pumps will be multiplied by 1.80 and 1.96 for failure to start and failure to run, respectively, to reflect the impact of changing the testing frequency from a 31-day staggered basis to a quarterly (non-staggered) basis as follows: Basic Event Basic Event Description Default Revised ID I Value I Value I L-MPCCOOOI-S MD AFW Pumps CCF to start (P504&P141) 1.19E-4 2.14E-4 L-MPCCol-lDR MD AFW Pumps CCF to run 24 hrs P504&Pi41) 1.40E-4 2.74E-4 6 of 8

PRA-02-04 Step 4: Total Risk due to Quarterly Testing Calculation To determine the total risk due to quarterly testing, the revised basic event values obtained in Steps 2 and 3 are substituted for the default values in the Safety Monitor. The following risk values result CDFAkpwQtrly 4.84E-05/yr LERFApwQtrly = 1.72E-06/yr Step 5: Increase in Risk Calculation To determine the increase in core damage frequency (CDF) and large early release frequency (LERF) due to changing the testing of the auxiliary feedwater pump requirement from a 31-day staggered to a quarterly frequency, the results of Step (baseline risk) are subtracted from the results of Step 4 (total risk due to quarterly testing). CDFincrease = CDFAFwQtrly CDFsaseline = 4.84E-05/yr - 4.10E-05/yr = 7.4E-6/yr LERFIncrease = LERFAEWQtr1y LERFBaseline = 1.72E-06/yr - 1.41E-06/yr = 3.1E-7/yr CONCLUSIONS The results of this evaluation show an increase in core damage and large, early release frequencies that correspond with "small' increases in risk per NRC Regulatory Guide 1.174. These increases in risk are assumed to reflect the bounding impact of the surveillance frequency change. In general, surveillance period changes are not expected to result in as large of proportional changes in reliability as that assumed in this analysis. Therefore, these results are considered to be bounding. Thus, this evaluation supports the change in the surveillance frequency of the SONGS Units 2 and 3 AFW pumps from a 31-day staggered basis to a quarterly basis. 7 of 8
