1.0 INTRODUCTION

The purpose of this document is to supplement the ECCS-LOCA evaluation results for the ENRICO FERMI 2 documented in the Reference 1 analysis. Specifically, using the limiting cases as defined in Reference 1, results are provided for GE14 fuel. The plant ECCS parameters and analysis methodology are consistent with those defined in Reference 1.

2.0 DESCRIPTION

OF MODELS Consistent with Reference 1, the ECCS-LOCA results are generated using the standard four GE-NE computer models. These models are LAMB, TASC, SAFER and GESTR-LOCA.

See Reference 1 for further details.

3.0 ANALYSIS PROCEDURE 3.1 LICENSING CRITERIA Consistent with Reference 1, the acceptance criteria for the ECCS-LOCA results are based on the Code of Federal Regulations, 10 CFR 50.46. See Reference 1 for further details.

3.2 SAFER/GESTR-LOCA LICENSING METHODOLOGY Consistent with Reference 1, the ECCS-LOCA analysis was generated using the SAFER/GESTR-LOCA licensing methodology (References 2, 3 and 4) as approved by the NRC (References 5 and 6).

3.3 GENERIC ANALYSIS The generic ECCS-LOCA analysis for the BWR-3/4 product line is described in Reference 1.

3.4 ENRICO FERMI 2 SPECIFIC ANALYSIS The ENRICO FERMI 2 specific analysis in Reference 1 demonstrated that the nominal and Appendix K PCT trends as a function of break size were consistent with one another and with the generic results. For large breaks, the DBA recirculation suction break with Division II Battery is the limiting break/failure combination for both Nominal and Appendix K assumptions. The Division I Battery failure is the limiting failure for small breaks.

• GE-NE-0000-0030-6565-R1 GEH PROPRIETARY INFORMATION 5.0 RESULTS 5.1 LARGE RECIRCULATION LINE BREAKS The limiting large break LOCA event for ENRICO FERMI 2 is the maximum recirculation suction line break. Several large recirculation suction line breaks were analyzed for GE14 with Nominal and Appendix K assumptions to confirm the limiting break and single failure combination. [I

)) The results of these analyses are given in Table 3 and Figures 1 and 2. These results show that the limiting break and single failure combination is the maximum recirculation suction line break with Division II Battery for both Nominal and Appendix K assumptions. ((

1]

For the maximum recirculation suction line break with Division II Battery and nominal assumptions, there is a rapid vessel depressurization due to vessel inventory loss through the break (Figure lb). ((

1]

The system response to a maximum recirculation suction line break with Division II Battery and Appendix K assumptions is similar to the case with nominal assumptions. There is a rapid vessel depressurization due to vessel inventory loss through the break (Figure 2b) but is slightly faster due to higher break flow from the Appendix K Moody Slip Flow Model. ((

)) This process can be observed in the hot bundle water level (Figure 2a), the peak cladding temperature (Figure 2c) and the hot node heat transfer coefficients (Figure 2d).

Overall the bundle heatup for the Appendix K case is higher than the nominal case due to higher bundle power and decay heat.

5.2 SMALL RECIRCULATION LINE BREAKS The most limiting single failure for small recirculation line breaks is the Division I Battery.

The small break cases were reanalyzed for GE14 with Nominal and Appendix K assumptions to determine the small break with the highest PCT. The results of these analyses are given in Table 4 and Figures 3 and 4. [1 5

GE-NE-0000-0030-6565-R1 GEH PROPRIETARY INFORMATION 5.3 NON-RECIRCULATION LINE BREAKS The analysis in Reference 1 demonstrated that the non-recirculation line break cases are clearly non-limiting and therefore not re-analyzed for GE14 transition. Note that the feedwater line break basis includes an assumption of operator action to depressurize the reactor during the Division I Battery failure scenario. This is necessary since HPCI may be lost through the break and therefore unable to restore level or depressurize the reactor.

5.4 ALTERNATE OPERATING MODES The limiting large break, the maximum recirculation suction line break, was reanalyzed for the MELLLA, Feedwater Temperature Reduction (FWTR), Increased Core Flow (ICF) and Single-Loop Operation (SLO) operating modes.

)) The MELLLA condition at EPU thermal power is not specifically analyzed since the core flow for this case is at 99% of rated core flow. This case is essentially covered by the rated case at EPU thermal power.

Overall these calculations show that the results for the case at rated conditions are still bounding.

GE-NE-0000-0030-6565-Ri GEH PROPRIETARY INFORMATION

))Therefore there is no additional PLHGR or MAPLHGR multiplier required from an ECCS-LOCA analysis viewpoint.

5.5 COMPLIANCE EVALUATIONS 5.5.1 Licensing Basis PCT Evaluation The Appendix K results confirm that the limiting break is the limiting small recirculation suction line (SBA). [I

))The Licensing Basis PCT for ENRICO FERMI 2 is calculated for GEl4 fuel based on the above Appendix K PCT and using the SAFER/GESTR-LOCA licensing methodology approved by NRC in Reference 5. ENRICO FERMI 2 unique variable uncertainties, including backflow leakage, ECCS signal, stored energy, gap pressure, and ADS time delay, were evaluated specifically for GEl4 fuel to determine plant-specific adders. The calculated Licensing Basis PCT is less than the Upper Bound PCT. Since the Licensing Basis PCT must be higher than the Upper Bound PCT, the Licensing Basis PCT is set to 1990'F.

5.5.2 Removal of the Current Requirement for Evaluation of Upper Bound PCT The NRC SER approving the original SAFER/GESTR-LOCA application methodology (described in Reference 3) placed a restriction of 1600'F on the Upper Bound PCT calculation. Additional supporting information was needed to support the use of the methodology for Upper Bound PCTs in excess of this limit. GENE provided this information on a generic basis in Reference 4. GENE received a SER from the NRC (Reference 6) eliminating the 1600'F restriction on the Upper Bound PCT. The elimination of the restriction on the Upper Bound PCT is applicable to all plants using the SAFER/GESTR-LOCA application methodology described in Reference 3, including ENRICO FERMI 2. In addition, the 1600'F restriction on the Upper Bound PCT is no longer applicable when evaluating the impact of changes and errors reported under the requirements of 10CFR50.46.

Plant-specific Upper Bound PCT Calculation The primary purpose of the Upper Bound PCT calculation is to demonstrate that the Licensing Basis PCT is sufficiently conservative by showing that the Licensing Basis PCT is higher than the Upper Bound PCT. The NRC SER approving the SAFER/GESTR-LOCA application methodology also required confirmation that the plant-specific operating parameters have been conservatively bounded by the models and inputs used in the generic calculations. The SER also required confirmation that the plant-specific ECCS configuration is consistent with the referenced plant class ECCS configuration for the purpose of applying the generic LTR Upper Bound PCT calculations to the plant-specific analysis. Because of the wide variation in plant specific operating parameters and ECCS performance parameters within the BWR product lines, it is difficult to judge whether an individual plant is bounded by the generic calculations. Therefore, the practice has been to calculate the Upper Bound 7

GE-NE-0000-0030-6565-RI GEH PROPRIETARY INFORMATION PCT on a plant-specific basis rather than rely on the generic Upper Bound PCT calculations in order to demonstrate that the Licensing Basis PCT is sufficiently conservative.

Reference 4 provided generic justification that the Licensing Basis PCT will be conservative with respect to the Upper Bound PCT and that the plant-specific Upper Bound PCT calculation was no longer necessary. The NRC SER in Reference 6 accepted this position by noting that since plant-specific Upper Bound PCT calculations have been performed for all plants, other means may be used to demonstrate compliance with the original SER limitations. These other means are acceptable provided there are no significant changes to the plant configuration that would invalidate the existing Upper Bound PCT calculations.

For the purposes of the Upper Bound PCT calculation,. the plant configuration includes the plant equipment and equipment performance (e.g., ECCS pumps and flow rates), fuel type, and the plant operating conditions (e.g., core power and flow) that may affect the PCT calculation. In order to demonstrate continued compliance with the original SER limitations, the PCT impact due to the changes in the plant configuration must be reviewed in order to confirm that the conclusions based on the original Upper Bound PCT calculation have not been invalidated by the changes.

[I]

The Upper Bound PCTs were also estimated for MELLLA and FWTR conditions, and at the current licensed thermal power, 3430 MWt. The results showed that the licensing basis PCT for all the power/flow points are below the 10CFR50.46 limit of 2200'F and the licensing basis PCT bound the corresponding Upper Bound PCT. Therefore, 10CFR50.46 acceptance criteria and the NRC SER requirements for SAFER/GESTR methodology are met for all the operating conditions.

As discussed above, the Upper Bound is no longer restricted by the 1600'F limit. Therefore, when evaluating the impact of changes and errors reported under the requirements of 10CFR50.46, the impact on the Upper Bound PCT no longer needs to be evaluated.

6.0 CONCLUSION

S The analysis contained in this report demonstrates that for GE14 fuel, the limiting break and single failure combination is the limiting small recirculation suction line break with Division I Battery for both Nominal and Appendix K assumptions.

Based on the limiting large and small breaks and applying the SAFER/GESTR ECCS-LOCA methodology, the ENRICO FERMI 2 ECCS-LOCA analysis was performed for the limiting LOCA event for GE14 fuel [I )). The results are summarized in Table 7. The analyses demonstrate that the limiting Licensing Basis PCT occurs for the limiting small recirculation suction line break. These results meet all licensing and SAFER/GESTR methodology analysis limits. ECCS-LOCA analysis results for all alternate modes (MELLL, ICF, SLO and FWTR) also meet all licensing limits.

The thermal limits applied to the GEl4 fuel in the ECCS-LOCA evaluation are summarized in Table 8.

Reference 8 concluded that HPCI flow changes above 1135 psia did not impact the LOCA evaluation. The reasons for this are two-fold.

1. The limiting LOCA evaluation at the time did not credit HPCI flow and,

2. Reactor pressure is less than the 1135 psia threshold by the time HPCI initiates for the Appendix K analysis.

While the limiting small break is now an event that credits HPCI, and is the limiting LOCA event, there is still no impact because reactor pressure is sufficiently low at the time of HPCI initiation. However, the limiting small break with the Division I battery failure was analyzed with no HPCI flow above 1135 psia, consistent with the OPL-4 in Appendix A, so a change in HPCI flow above 1135 psia continues to have no effect on the LOCA evaluation.

NI - GE Notes No. Note 1 Rated Nominal value to be consistent with Task 100 heat balance parameters at this condition. Appendix-K and off-rated power nominal cases calculated using Task 100 model at the case corresponding power and pressure.

2 Feedwater temperature to be determined consistent with the heat balance calculations at this condition.

3 The SLO power axis scaled based on EPU=100% rated power. The SLO core flow is 6"0 48% of the rated core flow in Item 1 .A.7 (Reference 7).

4 The 2 LPCI pump flow value selected for the analysis is conservative relative to the 2 LPCI pump specification of 25860 gpm. The analytical value includes a leakage flow reduction of 600 gpm.and additional flow reduction for conservatism. (Reference 2) 5 The 3 LPCI pump flow value selected for the analysis is conservative relative to the 3 LPCI pump specification of 30000 gpm. The analytical value includes a leakage flow reduction of 600 gpm and additional flow reduction for conservatism. (Reference 2) 6 The 4 LPCI pump is assumed to deliver at least as much as 3 pumps. Therefore, the analytical value selected is conservative relative to the 3 LPCI pump flow obtained after subtracting 600 gpm assumed in LPCI leakages (I.e. 30000 - 600 = 29400). (Reference 2) 7 The core spray one loop flow value selected for the analysis is conservative relative to the one loop flow specification of 6350 gpm. The analytical value includes a leakage flow reduction of 100 gpm and additional flow reduction for conservatism. (Reference 2) 8 Per Reference 8, Level 8=219 in and reference instrument zero = 366.31 in. Therefore, 366.31 in + 219 in =585.31 in above vessel zero.

9 Per Reference 8, Level 1=12.2 in and reference instrument zero = 366.31 in. Therefore, 366.31 in + 12.2 in =378.51 in above vessel zero.

10 The feedwater pumps are assumed to trip at the beginning of the event. The feedwater pumps are conservatively assumed to linearly coast down from the initial value to zero in 5 seconds. The feedwater flow coastdown has little effect on the results for the limiting break because the feedwater is injected into the downcomer where it then flows out the break. The feedwater flow is stopped immediately (no coastdown) for a feedwater line break. (Reference 9, Sec. 5.1.3)

N1 - GE Notes 11 The reactor recirculation pumps are assumed to be tripped at the beginning of the event. This assumption results in a rapid decrease in the core flow and results in a conservatively early boiling transition time for the fuel. Unless otherwise specified by the customer, a time constant of 5 seconds is assumed for the pump coastdown in the Short-Term Thermal Hydraulic Model (LAMB) for BWR/4 plants.

(Reference 9, Sec. 5.1.3) 12 An ECCS water temperature of 120'F is used for all calculations. This assumption decouples the SAFER/GESTR-LOCA analysis from the containment response. (Reference 9, Sec. 5.1.3) 13 LPCI leakage included in LPCI flows in Items 3.D.3, 3.D.4 and 3.D.5. See also notes 4, 5 and 6. Therefore, no additional leakage will be assumed in the analysis 14 LPCS leakage included in LPCS flows in Item 4.D. See also note 7. Therefore, no additional leakage will be assumed in the analysis 15 A 100°F temperature reduction is assumed per Reference 5, Item 1.1.G 16 Steam flow from HPCI Process Diagram (Ref. 14), "Mode C", Point 9, RPV at high pressure and suppression pool at low pressure.

17 Steam flow from HPCI Process Diagram (Ref. 14), "Mode D", Point 9, RPV at low pressure and suppression pool at low pressure.

18 To be calculated in the analysis.

19 Deleted 20 In the ECCS LOCA analysis, the minimum flow bypass (MFB) valves are assumed to be closed at the time of ECCS injection and the ECCS injection valves fully open. Therefore, the ECCS LOCA analysis does not account for flow through the MFB valves.

21 DTE's proposed response is a typo. DTE's acknowledgement in the following note from P. Tutton (DTE) to W. Roman (GE) (email sent on 8/12/03): "The correct value for OPL4 Item 8.E. is 1090 PSIG, which Item B.4.b of GE Ref. 2, DTE Calculation DC-6-34."

22 The resolved value is consistent with the previous Fermi SAFER/GESTR-LOCA analysis and the previous OPL-4, items B.3.b.I (Reference 2). Per AG-0019, App-20, it is more conservative to use a lower pressure for the "Maximum" pressure parameter in Item 6.c.1. Therefore, a 1135 Psia for the maximum pressure is conservative over the 1189 Psia proposed by DTE.

N2 - Customer Notes No. Note 1A NEDC-32313P, September 1994; The nominal core thermal power for SLO of 2470 mwth (62.5% of LPU) is not the correct initial power level to be assuming for the EPU SLO LOCA Analysis. 2470 mwth was a conservative initial condition assumption for the original Fermi2 SLO analysis transient analysis (MDE-56-0386), which has since been superseded by SLO analysis NEDC-32313P. Tech Spec 3.4.1 only allows SLO operation up to 67.2% of CLTP (2305 mwth). Therefore, the nominal core thermal power for EPU SLO should be 58.3% of LPU. Also, the 60% core flow assumption for SLO is incorrect. The single operating Recirc pump would have to operate at 100% speed to attain this core flow. The SLO analysis limits the speed of the single operating recirc pump to 75%, which translates to a core flow of approximately 48% of rated on the MELLL.

1B EPU is being licensed with a maximum core flow of 105% so analysis at 110% is not necessary.

1C Per Task T0307, Recirc Loop Flow at 100% core flow increases by 0.35 MIb/hr from CLTP to LPU. Per T0307 Section 3.3.3 Item 1, the BILBO calculated difference in drive flow is used with current operational data to determine the drive flow requirements at LPU conditions. Per Reference 1-3, the Total Rated Drive Flow at the beginning of the current operating cycle was empirically determined to be 31.973 Mlb/hr, or 15.99 Mlb/hr per pump. 15.99+0.35=16.34 Mlb/hr.

2A OPL 4A Note 11 B discusses the use of specific instrument values.

2B Deleted 2C LPCI and CS EDG delay times adjusted to 25 seconds for each system. This will recover the 5 seconds reassigned from the EDH delay to recirc valve stroke for LPCI as documented in GE-NE-B13-01920-12. This wiill result in CS total delay time to be 47 seconds amd LPCI total delay time to be 77 seconds.

3A otal Response time = 30 sec, Maximum valve stroke time = 24 sec.

3B JPer GE Ref. 2, this number is conservative engineering judgment not backed by specific data.

N2 - Customer Notes 3C A specific stroke time is not required for this valve. The GE standard for a gate valve is 12"/minute which would correspond to 20 seconds for a 4 inch valve.

3D Per DTE Drawings 6M721-5857, Rev. 0 Process Diagram RHR and 6M721-5690, Rev. E Process Schedules RHR, Mode G gives a two pump accident flow of 26,000 gpm 4A Fermi 2 Drawing M-5861, Rev. A Core Spray Process Diagram gives a Mode "runout' condition which is cited in GE Ref. 2 and a Mode D "Accident System Injection at Rated Core Spray (long term). The Mode D gives a lower flow of 6350 gpm.

4B A specific stroke time is not required for this valve. The GE standard for a gate valve is 12"/minute which would correspond to 15 seconds for a 3 inch valve.

4C Per DTE Ref. 4-1 & 4-3 there is a 5 second delay in the start of the Core Spray Pumps to sequence power to the motors. This is not related to reactor pressure vessel level.

4D The Core Spray System minimum flow valves would be closed during normal high flow core spray injection and therefore would not affect the LOCA model.

6A Per DTE Ref. 6-1 the system response time is 60 seconds with a 5 second allowance for instrument uncertainty.

6B The word "seconds" is acknowledged as a typo and is removed, the issue is resolved.

7A Design flow rate.

7B The RCIC High and Low Steam Flow values taken from Fermi 2 drawing 6M721-5859, Rev. D, DTE Ref. 7-1.

There is a lower steam flow of 8,400 lb/hr provided for Mode D, low reactor pressure injection from the suppression pool.

9A Per GE Ref. 2 - B.4.f, 3.48E6 is the value for four valves open, the value for one valve open is 870,000.

N2 - Customer Notes 10B The GE notes and references do not lead to the 0 leakage value. This issue is resolved by GE's revised notes 13 & 14.

11A Per Operating Procedure 23.107 the reactor water level is maintained between L4 (599.01 AVZ) and L7 (568.21 AVZ) The GE Proposed Value of 563.5 AVZ is approximately midway between these two points and is therefore acceptable.

118 This issue has been corrected, the following note is retained for record purposes. "The GE proposed values in 11 B are an inconsistent combination of Nominal Trip Set Points (NTSP), Allowable Values (AV) and Anayltical Limits (Alim). The heading of the section calls for "Set Points". The table below provided all .of the values for levels 1 through 8 for GE's use. All values are above vessel zero (AVZ).

The Alim values come from GE Ref. 2 Sub reference 38 (22A2919AB). The NTSP Values come from Reference 2-1 and the AV values come from various Fermi 2 Instrument Calcs. It is essential that GE assure that the proper value and consistent values are used for this evaluation" NTSP AV Alim Level 8 580.31 585.31 588.31 Level 7 568.21 Levels 4 and 7 are nominal alarm set points which do not have A Level 4 559.01 land Alim values Level 3 540.01 538.21 535.01 Level 2 477.41 470.11 457.51 Level 1 398.11 391.11 378.51 11C DTE has no access to Ref.. 5. Per OPL-3, there are 5 SRV's in each of the three subsets corresponding to opening pressures in 11.J 1,2 &3 11D Ref. 11 has been provided to DTE by GE email on 7/29/03.

11E The GE references is incorrectly stated, it should be Ref. 2 B.1 .d.l. [Corrected by GE. WIR-8/11/2003]

11F Per DTE Ref. 11-1 there are a total of 2 SRV's with low-low set; it is assumed that this is one from each group as defined in the

-_ question.

11 G Per Task T0400 OPL 4A the maximum suppression pool temperature is 95F. Per DTE Ref. 11-8 120F is used as a conservatism.

11H blank 11J Use value per GE note. GE note should say that the feedwater flows into the downcomer region, not the downcomers.

11K This value is the Allowable Value (AV) for CLTP A-53

GE-NE-0000-0030-6565-R1 GEH PROPRIETARY INFORMATION SINGLE FAILURE EVALUATION FOR SAFER/GESTR ANALYSIS(')

The table below shows the various combinations of Automatic Depressurization System (ADS), High Pressure Coolant Injection (HPCI) System, Core Spray (CS) System, and Low Pressure Coolant Injection (LPCI) System which might be operable in an assumed design basis accident situation. In performing the ECCS performance analysis with SAFER/GESTR, GE will assume that no postulated single active component will result in less than certain minimum combinations of systems remaining operable. The utility is requested to verify this assumption. The consequences of all possible single active electrical and mechanical failures an DC power source failures have been considered and have been found to have as a minimum one of the above combinations of systems remaining operable.

The following single, active failures will be considered in the ECCS performance evaluation:

Assumed Failure (1) Recirculation Line Break Systems Remaining(2)

Division I DC Power Source (Div I Battery) HPCI, 2 LPCI, 1 LPCS Division II DC Power Source (Div II Battery) 4 ADS, 2 LPCI, 1 LPCS (3)(4)

LPCI Injection Valve 4 ADS, HPCI, 2 LPCS'-3)

Diesel Generator (D/G) 4 ADS, HPCI, 2 LPCI, 1 LPCS (3)

HPCI 4 ADS, 4 LPCI, 2 LPCS (3)(4)

One ADS Valve 4 ADS, 4 LPCI, HPCI, 2 LPCS Notes for OPL-5 (1) Other postulated failures are not specifically considered because they all result in at least as much ECCS capacity as one of the above assumed failures.

(2) Systems remaining, as identified in this table, are with the concurrent loss of off-site power and are applicable to all non-ECCS line breaks. For a LOCA from an ECCS line break, the systems remaining are those listed, less the ECCS system in which the break is assumed.

(3) The analysis conservatively assumes 4 ADS valves available.

(4) The HPCI failure small break analysis (SBA) case is analyzed with 4 ADS valves available, if SBA PCT > than DBA this case will be reported as a sensitivity study and a case with all ADS valves operable (5 ADS valves) will also be evaluated.
