Title:

PSA Assessment of LER 03-004 (ESW Pump A Shaft Coupling Failure Event), Calculation PSA-039, Revision 1 Scope of activity being screened.

On September 1, 2003, the Perry Plant experienced a shaft coupling failure on the Emergency Service Water Pump A. Calculation PSA-039, Rev. 1, assesses that event for impact on nuclear safety in terms of Incremental Conditional Core Damage Probability (ICCDP) and Incremental Conditional Large Early Release Probability (ICLERP).

List the UFSAR-described design functions potentially affected by the activity.

Calculation PSA-039, Rev. 1, reviews the ESW Pump A shaft coupling failure event and describes the risk in terms of ICCDP and ICLERP. This calculation does not affect any systems, structures, or components (SSC) and as such, there are no design functions potentially affected by this activity.

10CFR 50.59 screening questions. Check the correct response.

1. Does the proposed activity involve a change to an SSC that adversely affects an E YES NO UFSAR-described design function?

2. Does the proposed activity involve a change to a procedure that adversely affects how E YES NO UFSAR-described SSC design functions are performed or controlled?

3. Does the proposed activity involve revising or replacing an UFSAR-described E YES Z NO evaluation methodology used in establishing the design bases or in the safety analyses?

4. Does the proposed activity involve a test or experiment not described in the UFSAR, EYES ZNO where an SSC is utilized or controlled in a manner that is outside the reference bounds of the design for that SSC or is inconsistent with analyses or descriptions in the UFSAR?

List the documents reviewed where relevant information was found, including section numbers and key words searched:

UFSAR Sections: None Change Request No:

Technical Specifications: None Other regulatory documents: None Keywords: Probabilistic, LER, ESW, Emergency Service Water E At least one question is answered YES. Perform a 10CFR50.59 Evaluation.

z All questions are answered NO. A 10CFR50.59 Evaluation is not required. Justify the determination:

Calculation PSA-039, Rev. 1, documents the assessment performed by PSA to determine the nuclear safety impact in terms of ICCDP and ICLERP due to the 09/01103 ESW Pump A shaft coupling failure event. An evaluation of an event does not cause an active or passive change to any SSC in the power plant. This evaluation changes License Event Report (LER)03-004, but the evaluation does not make a change to any procedure, instruction, or function as described in the UFSAR, nor does it affect any evaluation methodology described in the UFSAR. Additionally, this evaluation of the ESW Pump A shaft coupling failure event assesses the impact of an actual event, and therefore does not constitute a test or experiment.

Description of Change: This revision partitions the period that the ESW A pump was not available for the full 24-hour mission time assumed in the PSA model. Three partition periods were evaluated, each period with a different value for the availability of ESW A.

As part of the evaluation recovery was applied to unrealistic attributes in the PRA model that contribute to the increase in the core damage frequency with ESW A unavailable. Human error probabilities regarding the alignment of fast firewater were also re-evaluated and incorporated into the evaluation.

SUMMARY

1. The failure of ESW Pump A for 13.5 days results in an ICCDP of 8.5E-07.

2. The seismic ICCDP due to ESW A being unavailable for 13.5 days is about 4.4E-08. The ICCDP due to fires is about 7.8E-08. The contribution due to external flooding is considered to be non-significant. The ICCDP including all external events is approximated to be 9.7E-07.

3. The failure of ESW Pump A for 13.5 days also has an impact on the large early release probability. The ICLERP due to the unavailability of ESW Pump A for 13.5 days is less than 1.OE-07.

SUMMARY

LER 03-004 PSA-039, Revision 1 TITLE/

PSA Assessment for ESW Pump A Unavailability ESW A basic event set to failure the model represents the plant configuration with ESW A Pump unavailable. The modified PRA model was quantified with this change, resulting in a CDF of 6.348E-05 per year. The top 1000 cutsets from this latter run were placed in an EXCEL spreadsheet. These cutsets represent a CDF of 6.135E-05 per year (about 97 percent of the quantified CDF) and includes all cutsets with a value greater than 5.OE-09 per year.

These cutsets were evaluated and it was determined that several unrealistic scenarios rose to the top of the list. These unrealistic scenarios include:

1. Failure of containment venting through the RHR containment spray vent paths to the spent fuel pool when RHR B is in maintenance or test. For these cutsets containment venting through the RHR A containment spray vent path was assumed to be unavailable due to the logical failure of the RHR A pump. Venting using the RHR B containment spray vent path would only be unavailable if the maintenance or test activity included the vent valves. Since RHR A and RHR B are not allowed to be in test or maintenance simultaneously, the RHR A vent path should be available even if the RHR B path was not available. In addition, when the initiating event is the loss of offsite power, these cutsets also include the failure of the MSIV vent path even though the recovery of offsite power was successful.

To compensate for the unrealistic treatment of containment venting the basic event for failure of the operator to initiate containment vent via the RHR path (CVHICPEPC-RHR-E) with a value of 0.1 was added to these cutsets.

(CVHICPEPC-RHR-E already exists in the model and did not need to be created.)

2. When ECCS room cooling fails power recovery from a loss of offsite power event is required within 0.4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months for success. In reality, RHR and LPCS can operate for several hours without room cooling [17 ]. The recovery term R36 (non-recovery probability in 0.4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months ) was replaced with R2 (non-recovery probability in 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months ) in these cutsets. (R2 already exists in the model and did not need to be created.)

3. When RCIC and ECCS room cooling fails only 30 minutes is assumed to be available for alignment of firewater for injection. In reality, HPCS, LPCI and LPCS would operate for several hours without room cooling [17]. The HRA for aligning firewater was changed from FPHICPPS4:2RCIC4 (value of 2.1E-01) to FPHICPPS4:2RCIC1 (value of 6.5E-02) for these cutsets. See Attachments I and 2 for the changes in Hi values.

4. Less than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months was assumed to be available to control feedwater using the booster pumps when Instrument Air is not available and ECCS room cooling fails.

In reality, a longer time is available and the HRA for these cutsets was changed from FWHICPSN27-4:1IA (value of l.OE-01) to FWHICPSN27-4: IIL (value of 5.OE-03). (FWHICPSN27-4:1IL already exists in the model and did not need to be created.)

LER 03-004 PSA-039, Revision 1 TITLE/

SUBJECT:

PSA Assessment for ESW Pump A Unavailability After making the adjustments specified above, the CDF represented by the spreadsheet was reduced to 3.039E-05 per year. Assuming a comparable reduction to the remaining cutsets not included in the spreadsheet, the incremental increase in risk can be approximated. For the 5.25 days (August 31 at 1022 until September 5 at 1628) when the ESW Pump A was assumed to be unavailable, the incremental conditional core damage probability (ICCDP) can be approximated to be 3.28E-07. The ICCDP for this time partition was determined from the following equation:

1CCDP(l) = [CDFESW-A Unavail - CDFas2)

From August 27 at 0929 until August 31 at 1022 (approximately 4 days), it is assumed that ESW A would have been available for at least 1.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months prior to failure. Two PSA runs were made to evaluate this scenario. First a baseline case was run with all mission times set equal to 1.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months . Secondly, a case was setup with ESW A pump failed and a mission time of 22.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months . The baseline CDF for the 1.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months mission time is 7.813-06 per year. For the remaining 22.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months of the 24-hour mission time, the CDF with ESW A failed is 6.288E-05.

The top 1000 cutsets from both cases were placed in an EXCEL spreadsheet. The total CDF

for the 2000 cutsets is 6.515E-05 or about 92 percent of the total. Cutsets from the latter case were pruned to eliminate duplicates from the first case. Cutsets from the latter case were also modified to reduce failures given 1.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months of operation with ESW A available. For those cutsets were ESW A operated for 1.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months and then failed, operations would have the option of aligning the condensate transfer system for alternate injection. For the core damage scenarios where offsite power is available and ESW A operated for 1.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months , the operator action CTHICPPS4:4-ALT (operator fails to align condensate transfer for alternate injection) was added to the cutset. CTHICPPS4:4-ALT has a failure rate of 0.2 per demand.

(CTHICPPS4:4-AL already exists in the model and did not need to be created.) The final round of pruning reduced the significance of events such as cutsets where:

Core damage was the result of RHR B unavailability and the failure to remove decay heat from the containment.

Venting fails because the loss of offsite power makes the MSIV path unavailable, even though offsite power is recovered.

Core damage coincides with the failure to align the feedwater booster pumps within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months given the loss of instrument air.

The total CDF from the pruned 2000 cutsets was 3.033E-05 per year. The resulting ICCDP from the second partition time is 2.63E-07 and was determined from the following equation:

The two modified PSA cases for this partition time evaluated the scenario of ESW A being available for the initial 9.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months of a transient. First a baseline case was run with all mission times set equal to 9.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months . Secondly, a case was setup with ESW A pump failed and a mission time of 13.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months . The baseline CDF for the 9.5 hour5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months mission time is 8.195E-06 per year.

External Events (Seismic, Fire, and External Flooding)

Perry does not have PRA models for Seismic, Fire, or External Flooding. In development of the IPEEE a seismic margin analysis (SMA) was performed. Fire was addressed through FIVE (Fire-Induced Vulnerability Evaluation) and External Flooding was addressed via an assessment documented in Chapter 2.4 of the Updated Final Safety Analysis Report (UFSAR). The Regulator's process allows for qualitative assessments in absence of PRA models.

Seismic Assessment A seismic event that is less than an Operational Basis Earthquake (OBE, 0.075g) is not anticipated to have any impact on the plant. A transient may be initiated with a seismic event that is greater than an OBE. Acceleration probabilities for PNPP can be found in NUREG-1488 [16]. Acceleration due to gravity (g) is 980 centimeters/sec 2 . To convert to cm/sec2 :

(0.075g)(980 cm/sec/sec per g) = 73.5 cm/sec 2 NLIREG-1488 lists the annual mean probability for a seismic event with an acceleration of 75 cm/sec 2 as 2.466E-04. The most adverse impact of an OBE is anticipated to be cracked insulators on transmission lines leading to a Loss of Offsite Power (LOOP). Therefore, it is assumed that an OBE would result in a LOOP and that the capability of restoring offsite AC power would be gone. The conditional core damage probabilities for a seismic caused LOOP and a seismic caused LOOP without ESW A available are 9.505E-04 and 5.775E-03 respectively. Both of these probabilities were computed with no credit for recovering offsite AC power. (TI set to unity, all other initiators set to a small value, and events Ri through R72 set to logical failure.) Failure to recover offsite power ensures that all non-essential 7

PSA Assessment for ESW Pump A Unavailability equipment will not be available to mitigate the event. The increase in the CDF for an OBE with ESW A unavailable is computed to be about 1.19E-06 per year (change in CCDP times OBE probability). The ICCDP due to an OBE and ESW A being unavailable for 13.5 days is about 4.4E-08.

Fire Assessment The Perry Individual Plant Evaluation of External Events (IPEEE) [11] included an assessment of internal plant fires. Results from the Fire Induced Vulnerability Evaluation (FIVE) method were used for the fire assessment. With respect to the ESW A failure, only fire induced plant initiators that rely upon ESW A for mitigation would result in an increase in the CDF. Fire areas were screened for those areas where a fire would not result in a plant trip initiator or where a fire would result in the unavailability of ESW A. The fire areas that were not screened are:

PSA Assessment for ESW Pump A Unavailability YARD (T3A initiator)

The equipment listed provides front line system functions with significant risk impacts.

Programming these failures into the PSA model with internal flooding conditional core damage probabilities (CCDP) can be computed. A CCDP was computed for the configuration with and without the ESW A failure.

Listed initiating events were set equal to 1.0 and all other initiating events contributions, including the flooding initiating events, were discounted to obtain only the contribution from the listed initiating events. The computed CCDPs take credit for all of the mitigating functions in the PSA model. Note that the initiator chosen for the Yard fire areas will not result in the LOOP initiator. Qualitatively, fires occurring in the Yard will not take out all four power offsite power feeds into the Yard or both Startup Transformers. The most likely fire induced transient from a fire in the Yard is a plant trip with power conversion equipment available.

Following is a tabulation of the results from the FIVE analysis that was performed for the IPEEE, along with a comparison of the PSA results for the fire areas described above. "IPEEE Fire Core Damage Frequency" is the product of "IPEEE Fire Frequency" and "IPEEE Conditional Core Probability." "Increase in CDF due to ESW Failure" is determined from the difference of "PSA CCDP w/o ESW A Failure" and "PSA CCDP with ESW A Failure,"

multiplied by the "IPEEE Fire Frequency."

SUMMARY

LER 03-004 lPSA-039, Revision TITLE/

SUBJECT:

PSA Assessment for ESW Pump A Unavailability Summing the contributions from the individual fire areas for "Increase in CDF due to ESW Failure," the total increase in the CDF for fires due to ESW A being unavailable is about 2.1 06E-06 per year. For the 13.5 day period when ESW A was not available, the ICCDP due to fires is about 7.8E-08.

External Flooding There has been one occurrence of external flooding at the site due to the rupture of an underground Service Water pipe outside the Unit 1 Turbine Building. The Service Water piping has since been modified with an epoxy lining such that a similar reoccurrence is very unlikely. There is no other recorded incidence of external flooding at the site, either from the two streams draining the coastal watershed, or from Lake Erie. The terrain is relatively flat and gently sloping toward the lake. The soil is relatively permeable and contains sand layers in the upper reaches of the drainage area. The ground surface in much of the catchment area is forested with a heavy mulch ground cover. Due to the flat terrain, permeable upper soil layers and the small catchment areas, it is unlikely that this location has ever been subjected to flooding or is likely to experience severe flooding from surface runoff in the future. The contribution due to external flooding is considered to be non-significant.

ICLERP Assessment Using the PSA model with flooding the baseline large early release frequency (LERF) is 1.91E-07 per year. With ESW A unavailable the LERF increases to 4.42E-06 per year.

Using these results the incremental conditional large early release probability (ICLERP) for the 13.5 days with ESW A unavailable is about 1.56E-07. The LERF assessment did not partition the risk nor were unrealistic sequences pruned from the results as they were for the CDF assessment. The majority of the changes to reduce the core damage frequency result in cutsets that have an extended time prior to the onset of core damage. These changes are expected to also reduce the LERF. Using a comparable reduction in LERF as shown for the CDF (factor of 0.495) would result in an ICLERP of about 7.7E-08. Given that the reduction in CDF results in a reduction in LERF, it can be qualitatively stated that ICLERP is less than L.OE-07.

CONCLUSIONS:

1. The failure of ESW Pump A for 13.5 days results in an ICCDP of about 8.5E-07.

2. The seismic ICCDP due to ESW A being unavailable for 13.5 days is about 4.4E-08. The lCCDP due to fires is about 7.8E-08. The contribution due to external flooding is considered to be non-significant. The ICCDP including all external events is approximated to be 9.7E-07.

HFE Scenario

Description:

1. Initial Conditions: Steady state, full power operation.

2. Initiating Event: LOOP.

3. Accident sequence (preceding functional failures and successes): Diesel generators fail to start. Condensate and feedwater, ECCS, and HPCS pump are not available. RCIC is successful.

4. Preceding operator error or success in sequence: Successful depressurization.

5. Operator action success criteria and timing: Provide alternate injection into the RPV via HPCS piping. The water source is the Fire Water System, using the Diesel Fire Service Pumps, discharging through fire hoses connected from Fire Hydrant 24 to the HPCS Pump discharge line flush connection. 1 of 2 fire hoses is required for success. RCIC can run for 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months during which time the operators must line-up the alternate injection sources in anticipation of eventual RCIC failure.

6. Consequence of failure: Loss of core cooling

7. Key assumptions: Placekeeping aids are used in procedures

8. Notes: Due to the long time window, there is sufficient time to repeat the execution actions several times.

Although cognitive recovery is credited, execution recovery is conservatively not credited.
