ATTACHMENT 1 Response to Request for Additional Information NRC Request 1

1. The scenarios presented in your June 30, 2009, January 25, 2010, and July 1, 2010, submittals, which established the proposed revisions to TS 3.7.9 LCO, ACTIONS, and Surveillance Requirements (as stated in your January 25, 2010, submittal), assumed SX flow rates with the trains of each unit being cross connected and the opposite unit crosstie valves closed. Two SX pumps are running in the accident unit and one SX pump is running in the non-accident unit.

However, the updated final safety analysis report (UFSAR) currently states that the redundant SX loops can be operated as two separate loops in each unit, and TS Bases B 3.7.8 has provision to cross tie each unit's trains and also cross-tie the units as stated below:

UFSAR Section 9.2.1.2, Essential Service Water System, states that the essential service water system is divided into two redundant loops for each unit. The system may be operated with the loops cross-tied or as two separate loops.

TS Bases B 3.7.8 states that the SX system includes provisions to crosstie the trains (unit-specific crosstie), as well as provisions to crosstie the units (opposite-unit crosstie). The opposite-unit crosstie valves (1 SX005 and 2SX005) must both be open to accomplish the opposite-unit crosstie. The system is normally aligned with the unit-specific crosstie valves open and the opposite-unit crosstie valves closed.

a. Are the proposed revisions to TS 3.7.9 (LCO, ACTIONS and Surveillance Requirements) satisfactory for keeping basin temperature below 100°F when the SX system is aligned as two separate loops in one or both units? Are the proposed revisions to TS 3.7.9 satisfactory for maintaining basin temperature below 100°F when the SX system is aligned with the unit crosstie valves open? Please explain. If not, what course of action should be implemented such that the proposed revisions to TS 3.7.9 ensure the basin temperature will not exceed 100°F for all SX system operating alignments?

b. Do any procedures, UFSAR sections, or TS Bases need revision to ensure that the proposed revisions to TS 3.7.9 are satisfactory for all system operating alignments and modes of operation in your UFSAR and TS Bases? Please explain.

c. If the trains were operating as two separate 100ps1 as stated in UFSAR Section 9.2.1.2, discuss the validity of the proposed revision to TS 3.7.9 when the assumed single failure is a loss of an emergency diesel generator (EDG). Loss of an EDG could result in each unit's single SX pump (after a loss-of-coolant accident (LOCA)) drawing from the same tower with less than four fans running in that tower (depending on which fans are out of service). If this lineup is valid, discuss how the calculation would account for stratification or uneven mixing in the basin.

1: Assumes two separate loops means the returns to the cooling towers are also separate by closing valve 1 SX011.

ATTACHMENT 1 Response to Request for Additional Information Response 1

a. The Essential Service Water (SX) system is normally operated with the unit-specific train crosstie valves open and one of the unit crosstie valves closed. In the unlikely event that both opposite-unit crosstie valves are open for the postulated loss of offsite power (LOOP)/LOCA event, there would be some redistribution of flow within the SX system.

Based on sensitivity runs using the Byron SX system flow model, the net change in overall system flow and flow through the essential service water cooling tower (SXCT) cells is very small and would not significantly impact the previous analysis of basin temperature.

Additionally, the operating procedures for post-LOCA alignment of the component cooling (CC) system would align the Unit 0 CC heat exchanger (HX) to the accident unit. This operator action includes verifying/closing one of the unit crosstie valves (1 SX005 or 2SX005). Thus, the proposed revisions to Technical Specification (TS) 3.7.9 are satisfactory for maintaining basin temperature below 100 of when the SX system is aligned with the unit crosstie valves open.

With the loops separated, a postulated single failure that results in only one SX pump operating on the accident unit (EDG failure or SX pump failure) could result in water flow to only one SXCT. Depending on which SXCT fans are operable and the outside air wet bulb temperature, it is possible that the one SXCT with water flow could have less than the required number of operable SXCT fans available for cooling. An analysis (see Attachment

3) has been performed that shows for this postulated scenario, four SXCT fans on the SXCT with water flow are capable of maintaining basin temperature below 100 of. This issue is addressed further in Response 1.c. below.

b. The procedures, UFSAR sections, and TS Bases that are affected by the proposed revisions to TS 3.7.9 will be changed in accordance with existing license amendment procedures.

Changes to the TS Bases were previously submitted in Reference 1 and will be updated to reflect the currently proposed TS revisions. Bounding SX pump discharge temperature limits based on the analyses for the proposed TS have been put in place. Additionally, administrative controls have been put into place to require all eight SXCT fans to be operable when SX trains are separated.

c. If the SX trains were separated on both units and an accident occurred on one unit, a failure of one of the SX pumps or EDG on the accident unit could result in SX flow to only one of the two SXCTs. The same train SX pumps could be operating on the accident and non-accident units, and with the trains separated, essentially no flow would be provided to one of the SXCTs. The current and proposed TS on UHS operation allow up to two SXCT fans to be out of service without entering an LCO. In the scenario described above, if one or two of the out of service SXCT fans is on the SXCT with SX flow, the remaining SXCT fans would not have adequate heat removal capacity to maintain the SX basin water temperature below 100 of for design basis weather conditions.

Calculations indicated that with no SXCT fans out of service and the SX trains separated, the UHS temperature could be maintained at less than 100 of with four SXCT fans operating on the SXCT with flow. In this scenario, only one of the two SXCTs has significant water flow. Minimal mixing would occur between the SX basins; therefore, only half of the Page 2

ATTACHMENT 1 Response to Request for Additional Information SX basin water mass is considered available for heat storage in the calculations for the scenarios with SX trains separated.

A revision to the proposed TS is necessary to accommodate more restrictive SXCT fan requirements when either unit is operating with the SX trains in a split condition. Proposed TS Table 3.7.9-1 has been modified to indicate it applies to SXCT fans when SX trains on both units are in a cross-tied configuration, and a new Table 3.7.9-2 has been added to address when the SX trains on either unit are completely split. The Limiting Condition for Operations, Condition A, and Surveillance Requirement 3.7.9.2 have been modified to account for the addition of new Table 3.7.9-2. Also, Condition 8 has been modified to allow 72 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months to restore one or two inoperable SXCT fans to operable status while operating SX in a split configuration. In this condition, six operable SXCT fans are capable of mitigating the design basis accident with suspension of the single failure design criterion while in a TS Action as discussed in Generic Letter 80-30.

NRC Request 2 Assumption 3.4 of Appendix H of calculation M-MSD-009 (attachment 4 of the June 30, 2009 submittal) states that half of the reactor containment fan cooler (RCFC) heat load on the accident unit is shed at or prior to 30 minutes. Section 8 of Appendix H states, "Results are valid only if half of the RCFC heat load on the accident unit is shed at, or prior to, 30 minutes.

Procedures would have to be changed to implement this operator action."

Shedding the heat load from two of the four RCFCs would cause higher steam/air temperatures in containment for the remaining two operating RCFCs and thus increase their heat removal rate. Therefore, reducing the heat load contribution of the RCFCs by half seems to be a liberal assumption, especially since the same amount of energy has to be removed from containment whether two or four RCFCs are in operation after a LOCA. Securing two of the four RCFCs would seem to make the peak basin temperature occur later and higher than assuming that the half the heat input from containment to the basin was eliminated. As shown in the June 30, 2009, submittal (page 6 of 11), 4 of the 5 scenarios that establish the proposed TS 3.7.9 ACTIONS have a peak basin temperature above 99.5DF.

Please justify assumption 3.4 in light of the fact that the calculated maximum basin temperatures already peak very close to 100DF.

Response 2 Shedding two of the four RCFCs would result in a slow down in the rate of cooldown in containment and a higher heat removal rate from the two operating RCFCs. Attachment 3 of this document contains Calculation ATD-0063, Revision 0048, "Heat Load to the Ultimate Heat Sink During a Loss of Coolant Accident." As discussed in Assumption 3.2 of the calculation:

When two of four of the RCFCs are secured, the RCFC heat removal is assumed to be 50% of the RCFC heat removal of four RCFCs. With two RCFCs operating, the post-accident rate of containment cooldown will be less than when four RCFCs are assumed to be in operation. This would result in higher steam/air temperatures Page 3

ATTACHMENT 1 Response to Request for Additional Information entering the RCFC coils and some increase in heat removal for the two operating RCFCs. For calculating the peak UHS temperatures, the period of interest is the first 6000 seconds (See scenarios 5,6,7, and B of NED-M-MSD-009 [Ref. 4.31]). With four RCFCs operating the calculated containment steam/air temperature drops from 1BB.7 OF to 149.9 OF from time = 1799 seconds to time 5999 seconds (See Table 6 of the base (Rev. 4) calculation). With only two RCFCs and the same SX supply temperature, the drop in temperature over the same time period would be approximately one half or - 20 OF. The calculated maximum heat input from the RCFCs was conservatively based on an assumed SX supply temperature of 32 OF

[Ref. 4.51]. During the time period of concern, the SX temperature will actually be approaching the SX supply design temperature of 100 OF. This provides approximately 6B OF of margin in the approach temperature for the RCFC, which is greater than the expected 20 OF increase in the approach temperature due to securing two of the four RCFCs. Thus assuming 50% of the RCFC load is conservative.

The peak basin temperatures calculated are conservative because of the low SX supply temperature used in calculating the RCFC heat input to the UHS. The low SX temperature used to calculate heat input from the RCFCs offsets the higher heat removal rate due to the higher steam/air temperatures in containment for the remaining two operating RCFCs.

NRC Request 3 The proposed revisions to TS 3.7.9, when basin temperatures are above BO OF and fans are running in high speed, bound the current TS 3.7.9, whose basis considered the loss of an EDG as a Single failure. Since scenarios BC1 and BD1 present new TS, the loss of an EDG might not be bounded by scenario BC1 and/or scenario BD1 (above BO OF). Scenarios BC1 and BD1 each have a loss of 2 cooling tower fans and half the RCFC heat load. The loss of an EDG also results in loss of 2 cooling tower fans and half the RCFC heat load, as well as the loss of an SX pump in the accident unit.

a. Verify that the proposed revisions to TS 3.7.9 determined by scenarios BC1 and BD1 keep basin temperature below 100 OF if the single failure after a LOCA is a loss of an EDG. Please explain.

b. Review and discuss other single failures that need to be considered, if any, for the proposed revisions to TS 3.7.9, which were based on scenarios BC1 and BD1.

Response 3

a. A postulated failure of an EDG for Scenarios BC1 and BD1 would have the following impact:

o The SX pump on the accident unit powered by the failed EDG would not be running, which would result in lower flows to the SXCT cells. With lower water flows, the heat removal rate in the SXCT improves, which will lower the SX basin temperature.

Page 4

ATTACHMENT 1 Response to Request for Additional Information o

The RCFCs on the accident unit powered by the failed EOG would not be running. In Scenarios BC1 and B01, the heat input is from four RCFCs until operator action is assumed to be taken at, or prior to, 21 minutes. Thus, the peak heat input for a postulated EOG failure would be lower with loads later in the event becoming higher, since cool down of containment steam/air is slower.

o One train of ECCS on the accident unit powered by the failed EOG would not be running. With only one train of ECCS in operation, the peak residual heat removal (RHR) HX heat load to the UHS would be lower with loads later in the event becoming higher, since cooldown of containment sump water is slower.

o The SXCT configuration would be unchanged. A postulated failure of an EOG would result in the same number of failed SXCT fans and SX riser valves as the breaker failure currently postulated in Scenarios BC1 and B01.

The net result of a postulated EOG failure for Scenarios BC1 and B01 would be a lower peak basin temperature due to the lower peak load and improved tower performance.

b. As discussed in the January 25, 2010, response to NRC Request 5, the postulated active failures considered are: 1) containment spray pump failure, 2) SXCT fan failure, 3) EOG failure, 4) SX pump failure, and 5) SXCT bypass valve failure.

A containment spray pump failure results in slightly higher heat input from the accident unit which would be more than offset by the full cooling from the two SXCT fans that were postulated to fail in Scenarios BC1 and B01. The current analysis evaluates SXCT fan failures. The impact of an EOG failure is discussed in the response to NRC Request 3.a.

above. Failure of an SX pump results in lower flows to the SXCT cells which improves the heat removal rate in the SXCT and lowers the calculated SX basin temperature. SXCT bypass valve failures were evaluated in Scenarios 11, 12, and 13 in Reference 1.

NRC Request 4 Using the heat load given by the licensee in calculation M-MSO-009, the NRC staff performed an independent analysis and found a basin peak temperature above 100°F for scenarios BC and BO at approximately 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months after a LOCA. The heat load used by the NRC staff, being the same as in M-MSO-009, is half the actual containment heat load as noted in question 2, above.

What peak basin temperature does the licensee calculate for scenarios BC and BO (during cool down of the non-accident unit)? If basin temperature would exceed 100°F, what course of action is necessary to prevent basin temperature from exceeding 100°F for a LOCA and non-accident unit cool down?

Page 5

ATTACHMENT 1 Response to Request for Additional Information Response 4 When the time scale is extended for Scenarios 8C and 80 a second spike in basin temperature occurs when the non-accident unit is shutdown. The following peak basin temperatures were obtained:

(Minutes) 8C 101.3 634 80 (Riser Valves Open for Failed 101.3 634 Fans) 80 (Riser Valves Closed for 101.7 628 Failed Fans)

When the time scale is extended for all of the scenarios, two additional scenarios exceed 100° F during cool down of the accident unit. The following peak basin temperatures were obtained:

The RCS cool down rate is conservatively assumed to be 50 OF/hr. If required, the start of RHR cooling can be delayed on the non-accident unit and/or the cool down rate slowed. The appropriate procedures will be revised to caution operators on the non-accident unit to monitor the SX temperature and to manage the heat load inputs to the UHS from the non-accident unit to maintain the SX pump discharge temperature S 100 OF. The revision of the procedures is presented as a regulatory commitment in Attachment 4.

CALCULATION NO. NED-M-MSD-009 REVISION NO. 88 PAGE 2 1.0 PURPOSE This minor revision is issued to include additional Scenarios 8E and 8E1. The new scenarios evaluate the potential condition where the SX system trains are operating as two separate loops. If the SX trains were separated on both units, an accident occurs on one unit, a failure of one of the SX pump or EDG on the accident unit could result in SX flow to only one of the two SX cooling towers (the same train SX pumps could be operating on the accident and non-accident units and with the trains separated little flow would be provided to one of the cooling towers). The new scenarios will evaluate if four fans on one of the two SX cooling towers can maintain basin temperature below the SX cooling tower basin design temperature of 100°F. These new scenarios are included to respond to an 8/18/2010 NRC request of Additional Information (RAI) related to an UHS LAR [Ref. 4.1].

2.0 DESIGN INPUTS The design inputs specified in Appendix H of Revision 8 of this calculation apply to the present minor revision except the following:

2.1 The accident scenarios used in this minor revision of the calculation are modified from UHS-01 [Ref. 4.8] Attachment B to respond to an 8/18/10 NRC Request for Additional Information (RAI) related to an Ultimate Heat Sink License Amendment Request [Ref.

4.1] and are discussed in more detail in Sections 7.3.1 through 7.3.2.

2.2 The PIPE-FLO model from BYR96-259, Rev. 2 [Ref. 4.5] is used to develop flow through the two trains of the SX cooling tower for each accident scenario. See Section 7.1 for additional information.

2.3 Cooling tower performance curves for scenarios 8E and 8E1 are based on the model and methodology of BYR97-127, Rev. 1 [Ref. 4.4].

2.4 With the SX trains separated and no flow in one of the SX trains, only half of the SX water inventory is available for heat storage. Thuss the input for basin mass will be changed to 1.068 x 106 gallons x 0.5 = 0.534 x 10 gallons.

2.5 With only one SX train operating on the accident unit, the heat input to the UHS from the accident unit will be from one train of ECCS and two RCFCs. The heat input for this condition is obtained from Attachment A of ATD-0063, Rev. 004C [Ref. 4.2].

3.0 ASSUMPTIONS All assumptions in Appendix H of Revision 8 of this calculation apply to the present minor revision except the following:

3.1 For Scenarios 8E and 8E1 the fraction of flow cooled through the operating cells in Tower B is zero, thus the tower performance curve used for Tower B has no impact on the calculated basin temperature. In these cases, the same tower performance curve is used for both towers.

3.2 For Scenario 8E1, no cooling is credited prior to fan initiation at 10 minutes. Note, this Is assumption 3.3 from Revision 8 and is unchanged.

3.3 The heat loads taken from Attachment A of ATD-0063, Rev. 004C [Ref. 4.2] does not have any unverified assumptions.

6.0 METHOD OF ANALYSIS Minor revision 8B of this calculation will use the ESW cooling tower transient model from Revision 8 of this calCUlation to calculate the basin temperature response for additional

CALCULATION NO. NED-M-MSD-009 REVISION NO. 88 PAGE 4 Scenarios BE and BE1. Changes to the Revision B Mathcad model required to perform the Revision BB analysis are summarized as follows and shown in Appendix C:

1) For Scenarios BE and BE1 new flow rates were generated using PIPE-FLO [Design Input 2.2]. The lineup encompasses a single failure of either one SX pump or EDG occurring on the accident unit, resulting in operation of the 1 A and 2A pumps and no supply flow is provided to the B SX trains on either unit. PIPE-FLO model BA from BYR 96-259 [Ref. 4.5} and Appendix H of Revision B of this calculation was used as a starting point for PIPE-FLO models BE and BE1.

The SX system trains are completely separated and the CC HX flow is set to 16,000 gpm for CCHX-1 (CCHX-1 increases from B,Ooo gpm to 16,000 gpm from Scenario BA) and CCHX-2 (CCHX-2 is unchanged from Scenario BA).

2) Tower performance curves were generated for Scenarios BE and BE1 using MRUESC [Design Input 2.3]. For Tower B in both scenarios, there are no active cells. In this case, the same tower performance curve is used for both towers (see Assumption 3.1).

The Byron ESW cooling tower performance is acceptable if the calculated basin temperature is at or below the SX cooling tower basin design temperature of 100°F.

6.1 Scenario Descriptions Scenarios BE and BE1 were developed by modifying the scenarios in Attachment B of UHS-01 [Ref. 4.B] to account for a single failure of either one SX pump or EDG occurring on the accident unit, resulting in operation of the 1A and 2A pumps and no supply flow is provided to the B SX trains on either unit. The following is a short description of each scenario.

Note that from a hydraulic standpoint, the Pre-lOCA and Post-LOCA configurations are the same, unless operator action is taken to open or close valves.

Also, since no cooling is credited prior to fan operation at 10 minutes for Scenario BE1 (see Assumption 3.2) only the Post-LOCA configuration is shown below. Furthermore, fan operation does not affect the hydraulic analysis.

Scenario BE Cells OOS: None SX Pumps: One running on each unit (pre-LOCA)

Train A is completely separated from Train B Single failure: EDG - loss of power to SX pump 1 B [Ref. 4.2]

NED-M-MSD-009 REVISION NO. 88 Following 10 minute operator action to start fans and open riser valves Tower A: 4 riser valves open, 0 bypass valves open T ower A: 4 active cells, ° OOS celis Tower B: 4 riser valves open, 0 bypass valves open Tower B: 4 active celis, 0 OOS celis, 0 failed cells 6.2 Resistance Values PAGES The flow rates for the scenarios described in Section 6.1 were run by setting the SX pumps to 100% head and inserting a resistance value (K) into each riser and bypass line that is closed to achieve the desired flow rate of at least 250 gpm for each riser valve leakage and at least 375 gpm for each bypass valve leakage (see methodology from BYR96-259 [Ref. 4.5]). The SX pumps were run at 100% head (as opposed to 95%) with valve leakage modeled. Initial basin temperatures were used for fluid density (96°F for Scenario 8E and 82°F for Scenario 8E1). PIPE-FLO model 8A from BYR 96-259 [Ref.

4.5] and Appendix H of Revision 8 of this calculation was used as a starting point for PIPE-FLO models 8E and 8E1. Even though cooling tower efficiency improves with lower flow rates, more leakage (less flow to the active tower cells and more bypass around the active tower cells) is conservative, as it yields higher basin temperatures. This was confirmed in undocumented runs. The K values used to model valve leakage for each scenario are shown in Table 6-1. The results for each scenario are shown in Tables 7-1 and documented in Appendix A.

The resistance values (K) for each scenario are shown below in Table 6-1.

These figures plot T Hot vs T Cold for each tower performance curve for each cooling tower as provided by the methodology in BYR97-127 [Ref. 4.4]. For each scenario, two pOints were selected from the applicable tower performance curve (see Appendix B) to provide a linear approximation of tower performance over the range of T Hot and T Cold temperatures expected for that scenario. The selected points are checked against final results to confirm their applicability to the actual temperature range. These points are listed as Th1, Th2, Th3, Th4, Tc1, Tc2, Tc3, and Tc4 in the Mathcad models.

The single failure considered for Scenario 8E is the loss of an SX pump or and EDG.

The initial conditions assume a basin temperature of 96°F (maximum basin temperature aI/owed when eight fans are operable and running in high speed) with one SX pump running on each unit. This scenario assumes zero tower cells are out of service (OOS).

Initially, all fans are running and all the bypass valves are closed.

The total heat load to be used for this scenario is the "Total Heat Load to the UHS with 1 ECCS Train and 2 RCFCs" shown in Attachment A of ATD-0063, Rev. OO4C [Ref. 4.2J.

There is one set of parameters f, a, M1, 81, M2, B2, a, and 13 that are needed to determine the basin temperature response.

The UHS tower flows, based on Scenario 8E are shown in Table 7-1. The T hot vs T cold relationship is illustrated in Figure 8-1.

Both of these values are at or below the acceptance limit of 100°F.

7.3.2 Accident Scenario 8E1 This scenario is the same setup as Scenario 8E with the exception that no fans are running initially.

No cooling is credited prior to fan initiation at 10 minutes (see Assumption 3.2).

The single failure considered for Scenario 8E1 is the loss of an SX pump or and EDG.

The initial conditions assume a basin temperature of 82°F (maximum basin temperature allowed when eight fans are operable and not initially running in high speed) with one SX pump running on each unit.
