Dearborn 1.0 Background/Objective: 1.1 This calculation determines the Station Blackout (SBO) coping duration using NUMARC 87-00 methodology (Attachment B). Condition Report 02-07114 identified that a previous SBO coping duration calculation was attached to Engineering Memorandum EM-30633. As stated in the Condition Report, an EM is not appropriate for documenting an engineering calculation. This calculation is being performed to officially document the SBO coping duration in a formal calculation. 2.0 Design Inputs and

5.0 Assumptions
5.1 Not Applicable. 6.0 Acceptance Criteria: 6.1 Not Applicable. 7.0 Body Of Analysis: The page numbers below are referenced to NUMARC 87-00 7.1 Step one (Refer to NUMARC 87-00 Page 3-2): Determine the Off-site Power Design Characteristic Group. Note that per Attachment A memorandum from the Nuclear Utility Group on Station Blackout the generic response formats have been determined by the Staff to be an acceptable means of complying with the response requirements of the Rule, 10CFR50.63. 7.2 Part 1.A Page 3-3: Determine Site Susceptibility to Grid-Related Loss of Off-site Power Events. The average occurrences per NUREG-1032 for the majority of systems is about once per 100 site-years. Per E-mail (Attachment D) from Francis Etzel to John Ankney the grid loss of off-site power is 1 in 31.6 years for Unit 1 and 1 in 43.3 years for Unit 2. Since BV grid related loss of off-site power frequency does not exceed once per 20 years, BV is not classified P3. 7.3 Part 1.B Page 3-4: Estimate Frequency of Loss of Off-site Power Due to Extremely Severe Weather (ESW). Use method B based upon data obtained from the National Oceanic and Atmospheric Administration (NOAA) data summarized in Table 3-2 Page 3-6. The NRG provided this data for use by the utilities and is not required to be verified by the utility. From the table for Beaver Valley, the ESW Group is 1. 7.4 Part 1.C Page 3-7: Determine the Estimated Frequency of Loss of Off-site Power Due to Severe Weather (SW Group). Use the following equation on Page 3-7 to determine the frequency. f=(1.3*E-04)*h1 +b*h2+(1.2*E-02}h3+J:;*h4 Where: b=12.5 for sites with multiple rights of way i.e. Beaver Valley c=O since Beaver Valley (BV) is not vulnerable to affects of salt spray h1 =45 for BV per Table 3-3 Page 3-9 h2=0.0000692 for BV per Table 3-3 Page 3-9 h3=0.03 for BV per Table 3-3 Page 3-9 h4=0 for BV per Table 3-3 Page 3-9 f=0.00585+0.000865+0.00036+0:::0.007075 events per year Based upon the above frequency of loss of off-site the SW Group =2 per Table 3-4 Page 3-1 O

Dearborn 7.5 Part 1D Page 3-10: Evaluate Independence of Off-site Power System. Refer to Page 3-11. The Off-site Power System can be assigned Group 13 since "All Off-site power sources are connected to the unit's safe shutdown buses through (1) one switchyard, or(2) two or more electrically connected switchyard." and "The normal source of AC power is from the unit main generator and there is one automatic transfer and no manual transfers of all safe shutdown buses to one preferred or one alternate Off-site power source." 7 .6 Part 1E Page 3-11: Determine Off-site AC Power Design Characteristic Group (P Group). Refer to Page 3-12 Table 3-6a for 13 sites. Using the matrix for ESW=1 and SW=2 the Off-site power design Characteristic Group is P2.
- 7. 7 Step two:
Part 2A Page 3-15: Determine the Number of EAC Power Supplies Normally Available. Since BV is a single or multi-unit site with normally dedicated power supplies, we need to count the total number of standby power supplies normally available to the blacked-out unit's safe shutdown equipment that are not being used as an Alternate AC power source. The total number of standby power supplies normally available is 2. 7.8 Part 28 Page 3-15: Determine the Number of Necessary EAC Power Supplies. Since BV is a single or multi-unit site with normally dedicated power supplies, we need to count the total number of EAC standby power supplies on a per unit basis necessary to operate safe shutdown equipment following a loss of off-site power. The total number of standby power supplies necessary is 1. Part 2C Page 3-16: Using Table 3-7 on Page 3-16 the EAC Group is determined to be C. 7.9 Step Three Page 3-16: Determine the calculated EOG Reliability. Refer to Attachment F for the original reliability tests. On Unit 2 2EGS-EG2-2 was tested for 300 sta~s. The diesel generator successfully Piassed the 300 start test. A total of 272 valid start and load acceptance runs were made from warm standby temperatures with only one failure to meet the acceptance criteria. A total of 30 valid start and load acceptance runs were made from normal operating equilibrium temperatures with no failures to meet- the acceptance criteria. Per the purchase order 2BV-230, no tests were run on the other diesel. Therefore, the diesel reliability was 0.996. Per E-mail (Attachment E) dated 3-31-03 from the system engineer to design engineering the reliability for last diesel generator 100 starts (each diesel) has been above 97.5% for the diesels at both units. The continuing program is included in procedure 3BVT.11.36.2 and is based upon NUMARC 87-00. 7.10 Step Four, Page 3-17, Paragraph 3.2.4: Determine Allowed EDG Target Reliability. Beaver Valley has selected a target EOG reliability of 0.975 and use this target level in their reliability program.

- 1. P. 2 Section 2.5.1, should read:
"Sources of expected PWR and BWR reactor coolant inventory loss include (1) normal system leakage, (2) losses from letdown, (3) losses due to reactor coolant pump seal leakage and (4) BWR inventory loss due to SRV cycling and ADS actuation. Expected rates of reactor coolant inventory loss under station blackout conditions are not expected to result in core uncovering for a PWR or .,Jllore than a mo~_entary core uncovering for a BWR in the four-hour time period.
Therefore, makeup systems in addition to those currently available under blackout conditions are not expected to be
, required. As a result, it is expected that sufficient head . I exists to maintain core cooling under natural.circulation (including reflux boiling).

Re: Loss of offsite power frequencygi John, The grid related loss of offsite power frequency is 3.16E-021yr(or1 in 31.6 yrs) al Unit 1 and 2.31 E-02/ yr (or 1 in 43.3 yrs) al Unit 2. These are lhe plant specific values based on operating years and actual occurrences (1 in 15.8 yrs for Unit 1. 0 in 9.93 yrs al Unit 2). If you want an overall industry value it is 2.71 E-02/yr (or 1 in 36.9 yrs). which is based on EPRI Technical Report 1000158, *Losses of Off-Site Power at U.S. Nuclear Power Plants - Through 1999q, July 2000.

Re: Diesel Generator Reliability[] As per lhe Station Blackout program, I keep a database of EDG start demands, load demands, starl failures and load failures. Per the SBO program we are required to keep above 97.5%. Obviously, we respond lo any failure and make "prevent recurrence~ corrective actions if they occur. As or today, for Unit 1, over the last 100 unit start and load demands I am counting two failures. One was the seized river water pumps_ This is not really an EDG failure, but the EOG could not have ran with no river waler. The second is when the 4 kv bus undervoltage relay locked up and prevented the EDG from loading during the LOOP/SI test Again, not an EOG failure, but it could not have loaded. As of Loday, for Unit 2. over the last 100 unit start and load demands I have no failures. The BVT number is 3BVT 11.36.2 if you want lo review it and it is on my shelf above my desk.

Diesel Generalor Reliability Doug, I am presently perforrning a calculation where I need to know the reliability of the safety Diesel generators. Unit 1 UFSAR gi11es a reliability of 0.99 along with the basis. I cannot seem to find the reliability of the Unit 2 DGs_ Do you maintain a data base of the limes the DGs do not start when tested? Is there special maintenance done to assure reliability? Could you please respond to the above questions byWednesday4-2-03 so that I can answer a CA? Thanks, John

. . I I INTRODUCTION ll *..... *.* :i' A 300 Start and Load Acceptance Qualification Test was run on the second I; diesel generator unit S/N206147B for Beaver Valley Nuclear Power Station #2 *: --.','*, _-** . ;.- 1 as required by Stone and Webster Purchase Order 2BV-230.
Colt Engineering Instruction 11872825 Rev. 3 which was approved by Stone and Webster details the method of test and acceptance criteria. A total of 300 Start and Load Acceptance runs were required; 270 from wann standby temperatures and 30 from nonnal equilibrium temperatures, with no more than three failures allowed. RESULTS A total of 272 valid Start and load Acceptance runs were made from warm standby
- temperatures with only one failure to meet the acceptance criteria.
A total of 30 valid Start and Load Acceptance runs were made from normal operatina equilibr1um temperatures with no failures to meet the acceptance criteria. Additional runs were made which are discounted. That is, they are not considered valid runs nor fai1ures, for reasons such as operator errors within the parameters defined in the test procedure. I I The results of the Post Trial Inspection (per Paragraph IX of 11872825, Rev. 3) is covered in the material 1n Appendix P. I CONCLUSION
--1 The diesel generator unit successfully passed the 300 Start and load Acceptance Qualification Test.
