Joseph M. Farley Nuclear Plant - Units 1 and 2 Response to Supplemental Information Request Regarding Technical Specifications Condensate Storage Tank Minimum level ResP4:>m~es to Request for Supplemental Information to NL-12-2080 Response to Request for Supplemental Information Regarding LAR for TS 3.7.6 Question 1:

Regarding Standard Review Plan (SRP) Branch Technical Position (BTP)

Reactor Systems Branch (RSB) 5.1, LAR provides neither the assumption changes, nor the new BTP RSB 5.1 analysis reflecting the change to assumptions for determination of the revised water volume.

Clarify whether the current analysis satisfying BTP RSB 5.1 is changed in support of LAR. If the current analYSis is changed, provide the new analysis for NRC staff review.

Please also clarify whether the Technical Specifications (TSs) for CST water is based on the RSB 5.1 (natural circulation cooldown analysis) or not. If not, specify the basis (Le., the plant-specific analysis) supporting the and provide information to justify the associated basis.

a) Standard Review Plan (SRP) Branch Technical Position (BTP) Reactor Systems Branch (RSB) 5.1 was in the license amendment request (LAR) specifically for section G, "Auxiliary Feedwater Supply". This C!or-flnn of the RSB 5.1 states that the auxiliary feedwater system shall have a sufficient inventory to allow operation at hot shutdown for at 4

hours, followed by cooldown to the conditions permitting operation of the residual heat removal system (RHR). This inventory for cooldown is to be based on the longest cooldown time needed with either only onsite or only offsite power available with an assumed single failure. shows that the condensate tank (CST) has sufficient inventory in the maximum protected water area to hold reactor at hot standby for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and cooldown in 4 at 350 at a cooldown of 50 °F/hr, including:

the total water volume lost from ruptured of AFW pump reCirculation lines and unisolated flow instrumentation lines; volume for one reactor coolant pump (RCP) in operation for the duration of the event (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />) plus 10 megawatt thermal (MWt)

RCP heat added and decayed over one hour; minimum tank level to prevent vortexing.

Relative to the requirements of RSB 5.1, Section G, the ro",C!on calculation does not represent a change in satisfying the requirements of this section. The only change to assumptions made for determination of the revised CST water volume is the addition of an assumption that considers the potential for vortex formation. Thus, a minimum submergence is added to the CST required volume to prevent formation of a vortex.

1 to NL*12*2080 to Request for Supplemental Information Regarding LAR for 3.7.6 The event described above is the most limiting, requiring 154,054 gallons.

Other including those with either only onsite or only offsite power available with an assumed

failure, less inventory and are discussed in response to question 2.

b) The

The licensee stated in the LAR that the revised calculation for CST minimum volume is based upon additional assumptions regarding loads as referenced from the Component Design Basis Inspection also stated that plant events involving the usage of were reanalyzed with the revised calculation to identify the most limiting event to at the new minimum volume amount.

Provide additional information on how the new heat load assumptions were factored into the revised calculation. Also provide additional information on all of the events analyzed with revised calculation for the CST to verify how the licensee identified the most limiting event involving the a) (1) Heat Load Assumptions:

Decay heat load was based on assuming 102% power; Le., 102% of 2775 MWt (100% power). Thus, the volume to remove decay heat was based on 2831 MWt. Prior to the CDBI, the previous version of design basis calculation for the CST volume verification considered load on 100% power.

Sensible heat load assumption was based on the Tavg (hot) of OF plus 6 OF (583 for measurement uncertainty plant events where the unit is being shutdown. Prior to the CDBI, the previous of design basis calculation the CST volume verification determined sensible heat at Tavg (no load) of 547 conditions.

plant events where the unit is being held at hot standby, no heat load is added to the CST volume since the unit is not in transition to a shutdown mode but is held in hot standby with the intention to return unit to power.

-2 to NL~12~2080 Response to Request for Supplemental Information Regarding LAR for 3.7.6 Reactor Coolant Pump (RCP) heat load assumptions were based on several factors. First, if a loss of offsite power (LOSP) was event or concurrent with another event, no RCP heat was added during the hot standby or cooldown the unit. In these instances, only 10 MWt net heat input added the RCS was included due to power operation prior to the event. Secondly, if an LOSP was not the event or not concurrent with the event and the unit is being shutdown, RCP heat for operation of pump(s) during the cooldown and the heat added during power operation prior to the event were considered in determining the volume.

following are specific assumptions relative to RCP heat load included for the C\\I",.nT'" analyzed:

• Due power operation prior to an 1 0 MWt net heat input is added to Reactor Coolant System (RCS) for all events analyzed with exception to of Normal Feedwater (LONF) event, which conservatively adds 15 MWt input to RCS. This net heat is added to the volume requirements due to operation of the RCPs at power prior to the event.

• Technical Specification Bases Operability (9 hrs. at hot standby), Main Feedwater Line Break (MFWLB), Main Steam Line Break (MSLB) with LOSP, Small Break Loss of Coolant Accident (SBLOCA), and LOSP events were analyzed with no heat added during hot or cooldown.

each of these LOSP is as the event or concurrent with the event.

• TS Design (Normal Cooldown 2 hrs. hot standby with 4 hrs. cooldown) event assumed 1 RCP pump will operating during the 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> duration of the

This assumption is supported by Chapter 15 of the FSAR and WCAP 15097, "FNP Units 1 and 2 Replacements Generator Program NSSS Engineering Report Book 1, March 2001".

• Main Steam Break without LOSP event assumes three RCPs operate for the duration of the event which is determined by a conservative cooldown of 50°F/hr from Tavg (no~

These assumptions are supported by Chapter 15 of the Vortex During the Component Design Inspection 111.21), the of a vortex prevention calculation for the CST was identified as an unresolved issue. Subsequently, a Green non-cited violation was issued in NRC Quarterly Report "Joseph M.

July 20, 201 violation, a minimum submergence to prevent formation added (Enclosure Vortexing was considered for where a breach to the tank's unprotected walls or connecting lines could occur and allow to enter the tank beneath the tank's diaphragm. It has assumed that this breach is due to a tornado missile or seismic event. The that make this assumption are the Normal Cool down event and the cuc.,ue with a or event concurrent.

Analysis, that the provides cooling to remove decay heat and to down the unit following all in the analysis as discussed in the FSAR, 6 and 15. Upon review

-4 to NL-12-2080 Response to Request for Supplemental Information Regarding LAR for TS 3.7.6 FSAR chapters, as well as the TS Bases, the events that require cooling the RCS by the AFW were identified and the operability and design requirements of the CST per the LCO section of the CST TS Bases were defined. These events and requirements include:

LOSP wi Seismic Event LOSP MSLB wlo LOSP LNFW wlo LSOP

• Depressurization Main Steam LOSP wi Tornado Event SBLOCA

• MSLBw/LOSP MFWLB w/LOSP TS Bases - Design (Normal Cooldown)

TS Bases - Operability The TS Bases - Operability requirement of the CST is defined as having sufficient water available to maintain the RCS in MODE 3 for 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> with steam discharge to the atmosphere concurrent with a loss of offsite power. In addition, the TS Bases - Design, labeled "Normal Cooldown",

defines the design bases requirement of the CST as holding the unit in Mode 3 for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, followed by a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> cooldown to RHR entry conditions of 350°F at a rate of 50°F/hr.

The previous version of the design basis calculation identified the CST sizing components that made up the required volume. These sizing components consisted of decay heat, sensible heat, and RCP heat removal, as well as inventory loss due to AFW recirculation and instrumentation line ruptures. Pressurizer heater heat input to the RCS as required by the FSAR accident analysis for Loss of Normal Feedwater has been included in this version of the calculation. As discussed in the CDBI and documented in the CDBI report, a volume for vortex protection has been added to the CST minimum required volume for events that consider a seismic event or tornado event concurrent as well as CST inventory volume losses due to main steam and feedwater line break events.

For each event identified including the TS Bases - Operability and TS Bases - Design requirements, the CST minimum required volume to remove the specific heat load from the RCS was determined upon application of the assumptions as described above in response to question number 2(a). The required volumes of CST water to remove the different RCS heat components (decay, sensible, and RCP) were determined using a calometeric method whereby the enthalpy differences between the maximum allowable water temperature in the CST and the saturated steam pressure of the steam generator secondary side were used.

E1 - 5 to NL-12-2080 Response to Request for Supplemental Information Regarding LAR for TS 3.7.6 Portions of the AFW pump's minimum flow recirculation line and the four instrumentation lines attached to the AFW pump suction pipes are located outdoors and exposed to a potential tornado missile. Thus, the inventory losses due to the rupture of these lines have been considered in determining the CST required minimum flow for events whereby a tornado is assumed. These events include !\\Iormal Cooldown, LOSP with Tornado, and LOSP with Seismic event.

It is assumed that the recirculation lines from all three pumps would be isolated within 30 minutes. The recirculation flow from each pump is conservatively considered greater than the calculated value to accommodate for the slight decrease in frictional loss due to a line break.

The maximum volume of water lost during the 30 minutes span before isolation is the summation of all three purnps' minimum flow assumed. No inventory loss is considered from the CST through the AFW pump's recirculation connection to the tank since this connection is above the 164,000 gallon protected volume of the tank.

The break point of the four instrumentation lines is assumed to occur at the lowest location above the ground level where the instrumentation lines are exposed to missile impact. The inventory loss through the breaks is based on the flow through a discharge nozzle of a size equivalent to the ID of tubing at a pressure equivalent to the middle point height between the protected volume (164,000 gallons) level to the assumed break point of the tubing ignoring line losses. It is considered that these four instrumentation lines will not be isolated during the 6-hour unit cooldown or the 9-hour unit hot standby period.

Thus, the total inventory losses due to the ruptured instrumentation lines and the AFW pump's minimum flow recirculation lines were accounted for in determining the CST required minimum volume for events that occur concurrent with a potential tornado missile.

Additional CST inventory losses due to MSLB and MFWLB events were also considered in determining the minimum required volume of the CST.

The magnitude of these losses was determined from the design bases calculations of record, "Verification of AFW Flow Bases". The Units 1 and 2 calculations identify the required AFW flow rates for various normal and accident events which are supported by the AFW system. These flow models of the system for these accidents determined the flow rates through the main steam and main feedwater line breaks to the faulted steam generator. It has been assumed that the time required for isolation of the AFW flow through the MSLB break is 15 minutes and 30 minutes for the MFWLB. Given this information, time of isolation and magnitude of AFW flow through these breaks, the CST inventory losses were determined for each event and accounted for in the determination of the minimum required volume of the CST. No credit for AFW heat removal was applied for the MSLB event, even though some RCS heat removal does occur since the MSLB location is downstream of the faulted steam generator.

E1 - 6 to NL-12-2080 Response to Request for Supplemental Information Regarding LAR for TS 3.7.6 With the volume of CST water determined to remove each heat load component of the RCS, the CST inventory losses, and the minimum submergence level required to prevent vortex formation, the most limiting event could be determined. Summing the water volumes required for each sizing component revealed that the TS Bases - Design (Normal Cooldown) was the most limiting event. It is noted that this event includes several conservatisms which account for its greater volume requirement, such as the inventory losses due to the rupture of the AFW pump's minimum flow recirculation lines and the four instrumentation lines, as well as the vortex formation prevention volume. These added volumes are considered conservative since the Normal Cooldown event does not require the assumption of a tornado event concurrent with this event. The minimum required volume of 154,054 gallons for this event was used as the bases in establishing the greater than or equal to 164,000 gallons TS minimum level for the CST.

Question 3:

The LAR states that additional consideration regarding vortexing was applied during the revised calculation of the CST minimum volume. However, the LAR did not describe specific considerations that factored into changes made to the referenced revised calculations.

Provide additional information to describe how the licensee factored in the vortexing effects as part of the revised calculation for the CST volume.

SNC Response:

During the CDBI inspection, the NRC team identified an unresolved item (URI 05000348, 364/2011010-04) regarding the evaluation of the CST minimum required submergence for the AFW pumps, given the potential for vortex formation in the CST. During the inspection, it was observed that the design calculation for the CST sizing did not evaluate the effects of tornado missile damage to the un-protected portion of the CST which could create an air introduction path under the CST bladder which would allow a vortex formation. Subsequently, a Green non-cited violation was issued in the NRC Quarterly Report "Joseph M. Farley Nuclear Plant NRC Integrated Inspection Report 05000348/2012003; and 05000364/2012003", dated July 20, 2012.

In response to this URI and Green non-cited violation, compensatory measures have been taken to evaluate the minimum required submergence for the AFW pumps assuming the potential for vortex formation in the CST. This evaluation has been performed and issued as a separate and unique design calculation that determines the minimum submergence level required for the specific physical configuration of the AFW pump's suction piping (see Enclosure 3 which will be submitted in a separate letter as a supplement to this letter). The results of this E1 - 7 to NL-12-2080 Response to Request for Supplemental Information Regarding LAR for 3.7.6 calculation have been used as design input into determining the minimum required volume of the The CST has two 8" AFW suction pipes one for the TDAFW pump and one for both MDAFW pumps. Both suction pipes open 4" from the tank's bottom, facing down at a angle.

suction piping centers are approximately 1'-3" apart. The CST has an internal bladder that prevents introduction of air under normal operating conditions.

The primary technical reference utilized in determination of the minimum submergence level is Calculation-Note Number FAI/09-19, Rev. 0, titled "Vortex Evaluation for Vogtle and Farley RWSTs and Hatch CSTs", dated January 2009, by Fauske Associates, Inc. (Attachment 3 to Enclosure 3). Note Enclosure 3 contains Westinghouse Electric Company LLC proprietary information and is not included with this will be submitted in a separate letter as a supplement this letter.

This calculation-note was issued to Southern Nuclear by Westinghouse Nuclear Services letter 8458 dated 1/1612009 as supporting documentation to the GL 2008-01 This calculation-note was reviewed and evaluated for applicability to the Farley CST in determining the minimum submergence level required to prevent vortex formation.

This document states in the summary that data taken for tank configurations D.C.Cook, McGuire, Catawba, Oconee and Cooper nuclear plants all relate to the specific configurations used in the Southern Nuclear plants. In addition, it that specific measurements all provide justification for the manner in which air intrusion should for the Vogtle, Farley, and Hatch CSTs. The obtained from data taken produced results that are consistent with radial inflow conditions being the mechanism whereby significant gas intrusion would be drawn into the specific suction configurations. The downward facing suction configuration that is installed in CSTs acts to considerably suppress the potential for air intrusion. Evaluations of this radial inflow to a downward facing elbow resulted in a bounding correlation for misbehavior that is given by SID = 0.5(NFR}2 where the submergence S is the same as that defined in 7, Catawba Fueling Water Storage Vortex Study Tank and Suction Nozzle downward facing configuration. Since the Farley AFW pump's configuration is a 45 degree downward facing configuration, this correlation can be used to determine the submergence required to suppress air intrusion and vortex formation.

However, upon development of calculation for determining the minimum submergence (Enclosure 3) for the AFW pump's suction nm:zles. the equation also presented in the calculation-note FA1/09-19 based on the Harleman correlation was utilized (note Enclosure 3 contains Westinghouse Electric Company LLC proprietary information and is not included with this letter. Enclosure 3 will be submitted in a separate letter as a supplement to this letter).

correlation defines the crncnr'c level required above the horizontal entrance to a vertically E1 - 8 to NL-12-2080 Response to Request for Supplemental Information Regarding LAR for TS 3.7.6 downward suction as shown in Figure 5(a) of the FA1/09-19 Calculation Note FAI/09-19. This correlation is given as Sw'D = 0.75[NFr]o.4 on page 13 of 25. Even though the Farley suction nozzle is a 45 degree downward facing nozzle configuration, this Harleman correlation was used to provide a conservative submergence level. Using this vertically downward suction correlation increased the submergence level by a factor of two over the submergence for a 45 degree angle pipe or elbow nozzle facing downward. Thus, this greater submergence level was used in determining the volume component required in the CST sizing calculation for vortex prevention.

Question 4:

The LAR is incomplete and the staff cannot initiate a technical review until, at a minimum, the following is provided:

• Calculation of post-trip water requirements.

• Information that supports an independent evaluation of the level necessary to prevent vortexing.

• Provide the licensee's determination of the level that prevents vortexing.

• Applicable updated Final Safety Analysis Report sections.

SNC Response:

a) Calculation of post-trip water requirements.

The calculation SM-95-0961-001, Version 6, "Verification of CST Sizing Basis" (Enclosure 2 to this submittal), consists of the detail calculations, assumptions, and design inputs that form the bases for the determination of the post-trip water requirements of the CST. A detailed results and conclusions presented on sheets 21 and 22 of this calculation summarizes the minimum CST volume requirements for the TS Bases - Operability and TS Bases - Design (Normal Cooldown) requirements, including the volume requirement for the LONF without LOSP event which results in the worst case CST volume requirement of the FSAR Chapter 15 accidents.

b) Information that supports an independent evaluation of the level necessary to prevent vortexing.

The information necessary to support this request can be found in calculation SM-SNC335993-001 Version 2.0, titled "CST AFW Pump Suction - Submergence Analysis". This calculation will be included in, which will be submitted in a separate letter as a supplement to this letter. The purpose of this calcuation states "for the withdrawal of water from the CST, determine the minimum submergence water level in the tank to prevent vortexing at the AFW suction inlet when the flow rate is E1 - 9 to NL-12-2080 Response to Request for Supplemental Information Regarding LAR for TS 700 gpm. This level (water volume) has been incorporated as input into the "Verification of Sizing Basis" calculation, BM-95-0961-001 Version 6. Attached SM-SNC335993-001 Version 2.0 (Enclosure 3, which will be submitted in a separate letter as a supplement this is Fauske &Associates, Inc. Calculation-Note FAI/09-19 referenced in the response to question 3 above. As stated, calculation-note provides the bases for the method used in determination of submergence level required to prevent vortex formation and air intrusion into AFW pump's suction piping.

The summary of conclusions states the minimum submergence level required in the based on the operation of two (2) MDAFW pumps or the TDAFW pumps shall 9.78 inches from the bottom of the tank which includes 4 inches of unusable volume below the suction nozzles. Also, the minimum submergence level required in the based on the operation of one (1) MDAFW pump shall 8.36 inches from the bottom of the tank.

c) Provide the licensee's determination of the level prevents vortexing.

The equation based on the Harleman correlation presented on page 13 25 of FAI/09-19, Calculation-Note the submergence as water height above horizontal entrance to the vertically downward suction location as shown in Figure 5(a) of this calculation-note.

correlation is given as Sw'D ::: O.75[NFr]0.4. Even though the Farley suction nozzle is a 45 degree downward facing nozzle configuration that results in a lesser submergence level, as shown in Figure 7, the Harleman correlation was used provide a conservative level. Using this vertically downward suction correlation increased the submergence level a factor of two over the submergence for a 45 degree angle pipe or elbow nozzle facing downward. Thus, this greater submergence level was used in determining the volume component required in the sizing calculation for vortex prevention. The submergence level, based on the vertically downward suction configuration, the piping and the AFW pumps flow rates, was determined to be 5.78 inches. Since AFW pump's suction pipes open at 4 inches from the tank's bottom, the submergence level to determine the volume component to intrusion and vortex formation is 9.78 inches Enclosure which will be submitted in a letter as a supplement to this letter).

INTRODUCTION I PURPOSE The purpose of this calculation is to verify the sizing basis of the Condensate Storage Tank (CST). This calculation is therefore composed of the following determinations:

A. Determine the maximum protected volume of the CST.

B. Verify adequate volume is available in the missile protected portion of the CST for "Normal Cool down";

that is, to hold the reactor at hot standyby for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and cooldown in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to 350 OF at 50 OF/hr.

where RHR may be utilized for cooling. Up-rate power conditions of 2785 MWth (2775 MWth core power plus 10 MWth from the RCPs) will be considered in this evaluation. Also, verify adequate reserve margin is available considering a missile rupture of the recirculation line from the AFW pumps back to the CST and the four instrumentation lines for the two suction lines of the Auxiliary Feedwater Pumps. Since the portions of these lines are located outdoor and are exposed to a potential tornado missile, the impact to the CST and AFW systems due to a potential rupture of these lines will be evaluated. Also, verify adequate reserve margin is available to provide a minimum submergence water height above AFW pump nozzles to prevent vortex formation.

C. Verify adequate volume is available in the missile protected portion of the CST for a" Main Feedwater Line Break with Loss of Off-Site Power" event; that is, to hold the reactor at hot standyby for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and cool down in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> to 350 OF at 50 OF/hr. where RHR may be utilized for cooling. Up-rate power conditions of 2785 MWth (2775 MWth core power plus 10 MWth from the RCPs) will be considered in this evaluation. Also, verify adequate reserve margin is available considering the loss of CST inventory due to I the main feedwater line break. No other line failures, such as, AFW pumps recirculation or CST instrument lines, are considered to fail due to a seismic event or tornado generated missile. Also, no reserve margin is required to provide a minimum submergence water height above AFW pump nozzles to prevent vortex formation since no lines attached to the tank are assumed to fail allowing air to enter the tank.

D. Verify CST capacity based on the Technical Specification Bases (OPERABILITY) that sufficient water is available to maintain the RCS at hot standby conditions for 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> with steam discharge to the atmosphere concurrent with a total loss of off-site power. Up-rate power conditions will be also considered for this case (Reference 4).

E. Verify adequate volume is available in the missile protected portion of the CST for a "Loss of Normal Feedwater" (LONF) event w/o Loss of Off-Site Power; that is, verify sufficient water is available to maintain the RCS at hot standby conditions for 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> with steam discharge to the atmosphere. Up-rate power conditions of 2775 MWth core power will be considered in this evaluation. The WCAP 15097 (Ref.

22) assumes a conservatively large RCP net heat input of 15MWt. This initial net heat input of 15MWt is assumed to decay over 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. Per this WCAP, all three(3) RCPs operate at the initiation of the event for 10 mins and one(1) RCP operates for the duration of the event; i.e. 9 hrs. in hot standby. No line failures, such as, AFW pumps recirculation or CST instrument lines, are considered to fail due to a seismic event BM-95-0961-001 Calculations.docx

METHODOLOGY calculation code MAP*i21, Version V01 was used to the decay heat of the core. This model calculates decay heat based on NRC Branch Technical Position 9-2. FSAR section 9A.1 and figure 9A-2 discusses the conservatism of basing the decay heat on Branch Technical Position ASB 9-2 as opposed to the original provided by Westinghouse specification Revision 1 and as presented in FSAR figure 9A-i.

The results of heat as shown in Appendix "AI! is based on of 2785 MWt (2775 MWt core power plus 10 MWt from The model decays the total in Btu/hr equivalent to 2785 MWt, including the heat. This version of the calculation separates the decay heat due to fission products from RCP and applies both to the CST volume sizing individually. That MWt due to fission product heat is decayed according to the model; however, the 10 MWt to heat is decayed over a one(1) hour period and both applied to the required CST volume separately.

This calculation CST volume required for four(4) different plant events: Normal Cooldown hrs at hot standby and 4 to 350°F at 50"F/hr where RHR is utilized for cooling), Main Break w LOSP hrs at hot standby and 4 hrs to at 50°F/hr where RHR is utilized for cooling), Hot Standby for 9 hrs. wI LOSP per T.S.

Several different heat loads, volume due to tornado missiles, events and breaks, and a minimum submergence level to prevent vortex formation have been determined for each of the plant events, as to determine the CST volume required to cooldown the for each plant event.

BM-95-0961-001 6 of 23 Determine the maximum protected volume of the CST. This volume is based on the elevation of the condensate makeup and return line, 24" HBD-252. Since this line connects to the CST in the missile protected portion of the tank, is seismic category II, not protected from a tornado missile and the only non missile protected Seismic Category II line in the missile protected portion of the tank this line establishes maximum protected volume of the tank. Thus, the maximum protected volume of the CST is determined by the elevation of the invert of the condensate makeup and return line since failure of this line is assumed based on it's design.

From vendor documents U-161693 and U-213481 (Reference 11), the 24 inch dia, condensate and makeup return nozzle is 14'-2 SA" from the bottom of tank. The piping 24" HBD piping and tank nozzle is Sch. 40 with a wall thickness of 0.375 inches. Therefore, the invert of the pipe is:

• Condo Makeup Invert = 14.229 - (10/2), where the 10 of the piping is 23.250 in.

= 13.260 ft Now, Tank bottom area: rrr2 =rr (23 ft.)2 = 1662 ft2 (Reference 11)

Based on 24" HBD-252 piping invert of 13.260 ft, the maximum protected volume of the CST is:

Pumping Capacity and Inventory Loss During normal plant cooldown, operating of one MDAFW pump will permit a maximum initial cooldown rate of 100°F/Hr. Each of the MDAFW pump is to supply the steam generators with 100 percent of the required feedwater flow for a normal cool down of the reactor coolant system (References 1 and Therefore, one MDAFW pump is sufficient for a normal cooling operation with a cooldown rate of 50 assumed calculation.

approach for calculation, however, it is modeled for all three AFW pumps (the TDAFW and two MDAFW pumps, each at the design flow rate of 700 and 350 gpm, respectively) to operate for the first 30 minutes before the TDAFW and one MDAFW pumps are For normal plant cooldown, the AFWS is placed under manual control to supply feedwater to steam generators for removal of decay and sensible heat from the reactor system. The TDAFW pump is designed to manually or automatically initiated to rated capacity and within 1 minute from starting at rest at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> independent any ac power (Reference 1). Operator action to secure the TDAFW and one MDAFW pump within 30 minutes will be adequate for this calculation purpose.

It is to check that this operational mode will deliver sufficient water during the period (6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />) to meet the volume of 1 19 gallons above.

Therefore, the pumps will cover required water volume during the 6-hour period.

The volume of water out from a break in the pump recirculation line will calculated with an assumption that the ruptured minimum flow recirculation will be isolated within minutes. Three recirculation lines of the pumps form one 6-inch line to the It is even though single 6-inch return line would rupture at a location near the all the three pump recirculation lines would be isolated.

BM-95-0961-001 Since valves for the recirculation lines can be closed manually inside the plant, 30-minute span for the action is considered sufficient (Reference Section B.3.7.6).

9 and 10, the maximum recirculation flow for the TOAFW pumps is 100 gpm, and 50 gpm for MOAFW pump.

recirculation flow are slightly higher than calculated to conservatively accommodate the slight in frictional loss due to a line break.

Thus, the maximum volume of water will lost during the 30-minute span from recirculation line failure while all three AFW pumps are in operation is:

(100 + 50 + 50)gpm x hour =

Since the nozzle of AFW pump recirculation is located at 19 above the which is well above the height (1 feet, see below calculation) of the protected 164,832 gallon volume, or even above protected height of the tank (16') (Reference 11), a possibility of water coming out from the through the ruptured recirculation line is not considered.

From 14, 15, 16, 17 and 18, the four flow instrumentation lines branch out from two AFW pump suction lines at EI. 150 ft. location. Since the locations of the branch-out are in the pipe trench, for a conservative calculation purpose, the break point of the instrumentation is assumed to happen at location above the ground level 1

where the instrumentation are to missile impact. This is the same elevation as the pump suction nozzle at the instrument tubing is 3/8" with 17). In order to calculate the flow rate at the rupture assume the in the 8" pump suction and the instrument tubing are Ignored. This will give a conservative result for the flow rate. Since the lower 164,832 gallon volume of the tank shall be reserved for handling decay heat and cooldown, the height of this water volume in tank Tank bottom area: TI r2 TI (23ft)2 = 1662 (Reference 11)

2-9, the water flow from the break point is calculated by extrapolation. The break size of the tubing (0.245" 10) is approximately equivalent to 1/4". The discharges of 1/4" nozzle at 10 and 15 psi are 5.91 and 7.24 gpm, respectively (Reference 6).

Taking a middle pOint of the fluid at the instrument break point, or 2.9 psi, and ignoring all the and effect of the AFW pump suction conservatism, then the flow at the break points is calculated as:

5.91 gpm - {[(7.24 - 5.91 )/(15-1 0)] x (10-2.9)}

5.91 - 1.88 4.03 gpm per line Total outflow for four instrumentation lines: 4.03 x 4 lines 16.1 gpm If we consider that instrumentation tubing will not isolated during 6-hour cooldown period, than the total volume lost from the ruptured instrument for 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> is 16.1 x 6 x 60 = 5803 gallons.

Southern Nuclear Design Calculations In addition to the conservative scenario assumed in calculation, result is even more conservative for the following aspects.

First, operating aU pumps at the beginning of the normal plant cooldown is a highly conservative scenario. Only one or two pumps would be used for this purpose, which would make the water lost from the ruptured line much less than the calculated The water volume lost from the one 6-inch recirculation line was calculated by combining all the recirculation flows (200 gpm) from each AFW pumps.

Secondly, the volume of water required for decay and sensible heat removal calculated based on the enthalpy water at 1155 psia.

This RCP heat is based on net heat input of 10 MWt from the full power operation of the unit prior to the event per WCAP-15097. The FSAR Section 15.4.2.1 does not assume a conservatively large RC P heat of 15MWt.

The amount of water needed for this MFWLB event is 141,449 gallons.

This analysis also shows that an adequate volume of water is available in the missile protected portion of the CST to maintain the RCS at hot standby conditions for 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> with steam discharging to the atmosphere for the Loss of Normal Feedwater without Loss-of-Offsite Power event. The amount of water needed for this LONF event is 148,625 gallons.

All of these required water volumes are within the maximum protected water amount of 164,832 gallons for the CST and the Normal Cooldown has been determined to be the most limiting event for the sizing of the CST volume.

Therefore, the CST capacity is adequate to remove the reactor decay heat from 102% RTP, RCS sensible heat, and RCP heat for various conditions described above which include the water loss from rupture of the unprotected lines due to potential missile impact or a seismic event, inventory loss due to a main steam line break and AFW pump suction vortex prevention.

RE: CST Sizing Verification* MSLB and MFWlB Events (Mass Flow Question)

Willie, We ran simulator scenarios this morning, but I've been on a teleconference all day since. All scenarios were done with a three man crew and intentionally done at a slow pace to bias the timeline towards a longer completion. There were no failures.

The first scenario was a 12 mpph (million mass per hour) MSlB in 1B SG upstream of the MSIVs with Reps in service. The time line was as follows:

07;37;30 Event start (MSIVs automatically close) 07:42.:00 AFW isolated to IB SG per early action by UO 07:43;00 EEP-O steps 8 & 9 reached (these steps direct the actions which the UO performed at 07:42:00) 07:46:30 Transition from EEP-O to EEP-2 07:53;00 FinallB SG isolation per EEP-2 The second scenario was a 20 mpph MFWlB inside CTMT with Reps in service. The time line was as follows:

08:02:00 Event start (M5IVS automatically automatic 51 occurs EEP-O immediate actions requiring longer time for completion) 08:08:00 AFW isolated to 18 SG per EEP-O (early UO action intentionally not allowed) 08:10:00 Transition from EEP-O to EEP-2 08:16:00 FinallB SG isolation complete per EEP-2 I was not able to talk to you this before the simulator runs so our break sizes differ from those used in your calculations. Also, I dropped the ball and left the Reps on during the MFWlB. I don't think that either of these differences would measurably affect the time lines up to AFW isolation to the faulted SG. As you can see, AFW flow to the faulted SG was isolated in 6 minutes or less in each case and there was only Nl minute difference when operator action was allowed instead of forcing the crew to wait for direction. Please review these results and let me know If you need more but I believe these time lines support a 30 minute time for AFW isolation to the faulted SG as a conservative value. As an the initial total AFW flow rate to all three SGs was Nll00 gpm in each case and the final throttled total AFW flow rate to the two intact 5Gs was N180 gpm with stable SG levels and RCS temperature.

Thom; 1

Here's the mass flow rates taken from the AFW flow balance WhlCl) defines flows to the faulted S?G as well as the intact I've taken these flow in gpm and converted them to mass flow rates at the max. temperature of the CST. I not sure if you should use the flow to the faulted or flow to all But here is flow to both.

MFWlB: Faulted S/G - 2.47 X10115 lBm/Hr.; All

- 3.25)( 10"5 lBm/Hr. ; the difference is what is flowing to the intact MSlB w/o LOSP: Faulted

- 3.79 x 1011 5lBm/Hr.; All S/Gs 1.02 x 1O"6lbm/Hr.; the difference is what is flowing to the intact
