Additional Information Supporting Request for Emergency License Amendment to Technical Specification 3.7.3, "Ultimate Heat Sink" References : 1 . Letter from D. M . Benyak (Exelon Generation Company, LLC) to U .S . NRC, "Request for a License Amendment to Technical Specification 3.7.3, 'Ultimate Heat Sink,"' dated June 29, 2007
- 2. Letter from P. R . Simpson (Exelon Generation Company, LLC) to U. S . NRC, "Additional Information Supporting Request for a License Amendment to Technical Specification 3.7.3, "Ultimate Heat Sink," and Request for Processing on an Emergency Basis," dated August 1, 2007 In Reference 1, as supplemented by Reference 2, Exelon Generation Company, LLC (EGC) requested a change to the Technical Specifications (TS) of Facility Operating License Nos. NPF-11 and NPF-18 for LaSalle County Station (LSCS), Units 1 and 2. The proposed change increased the maximum allowed TS temperature limit, contained in TS Surveillance Requirement 3.7.3 .1, of the cooling water supplied to the plant from the Core Standby Cooling System (CSCS) pond (i.e., the Ultimate Heat Sink (UHS)) from 100 °F to 101 .25 °F . The proposed change was based on a reduction in instrument uncertainty resulting from the replacement of the originally installed thermocouples with precision resistance temperature devices .
During a conference call with the NRC on August 2, 2007, the NRC requested EGC to submit one of the references listed in Attachment 2 of Reference 2. As requested, the Attachment to this letter contains EC 356645, "Assessment of High Lake Temperature On the Functionality of the Plant (Summer Readiness 2005)," Revision 1 .
August 2, 2007 U. S. Nuclear Regulatory Commission Page 2 As discussed in Section 4.2 of Attachment 2 to Reference 2, the results of the evaluation demonstrated an increase in the maximum inlet temperature of cooling water supplied to the plant from the CSCS pond could be justified . However, although margin exists to support increasing the actual inlet temperature, the proposed increase in the allowable indicated temperature is based solely on a reduction of the existing instrument loop uncertainty value. No change in the actual inlet temperature was credited ; therefore, there is no change in the containment pressure response, loss-of-coolant accident (LOCA) and non-LOCA analyses, and there is no increase in risk associated with the post-accident heat removal. Thus, the attached evaluation has no impact on the technical justification for the proposed change .
EGC has reviewed the information supporting a finding of no significant hazards consideration that was previously provided to the NRC in Attachment 2 of Reference 2 . The information provided in this submittal does not affect the bases for concluding that the proposed license amendment does not involve a significant hazards consideration.
There are no regulatory commitments contained in this letter . Should you have any questions concerning this letter, please contact Ms. Alison Mackellar at (630) 657-2817 .
I declare under penalty of perjury that the foregoing is true and correct. Executed on the 2nd day of August 2007 .
Respectfully, Darin M. Benyak Director, Licensing

EC 356645, "Assessment of High Lake Temperature On the Functionality of the Plant (Summer Readiness 2005)," Revision 1
ATTACHMENT EC 356645, "Assessment of High Lake Temperature On the Functionality of the Plant (Summer Readiness 2005)," Revision 1
EC 356645, Rev. 1 Page 1 of 15 Assessment of High Lake Temperature On the Functionality of the Plant (Summer Readiness 2005)
REASON FOR EVALUATION :
This EC revision (Rev . 1) evaluates and documents any changes to EC 354788, a previous evaluation (dated 4/27/05) of plant components for higher inlet cooling water temperatures, and revision 0 of this EC (356645) . The EC is prepared to support Summer 2005 Readiness. In the event that the plant's inlet cooling water temperature approaches and is predicted to exceed the Tech Spec SR 3 .7 .3 .1 UHS temperature limit of </= 100 °F, a temporary increase in this limit to 102 °F will likely be requested from the regulator. This increased limit (102 °F) will be the starting temperature for postulated accident analysis involving the UHS and the operating limit for non-safety related equipment.
DESCRIPTION OF CHANGE/SCOPE/APPROACH:
This assessment will address the consequences of an increase in the temperature of cooling water supplied to the plant upon both safety-related and nonsafety related systems. For safety-related systems, the applicable components are part of the CSCS cooling system . These are evaluated for a higher inlet cooling water temperature of 106 °F, versus the current 104 °F (Reference 1). The assessment is based on current (as of the preparation date of this EC) plant equipment condition, e.g. current equipment inspections, monitoring, heat exchanger tube plugging and performance testing information.
The UHS at the time of a postulated LOCA and concurrent cooling lake dike failure will be at a starting temperature of 102 °F. The CSCS piping systems have a design temperature of 200 °F so this temperature increase can be accommodated by the piping systems involved.
The UHS has been previously analyzed utilizing the existing calculation model (Reference
- 2) to determine the peak inlet cooling water temperature following a LOCA and cooling lake dike failure, based on a starting temperature of 100 °F for small siltation depths . (e.g.
up to 6-inches siltation). The most current siltation surveillance indicates the average siltation depth is less than 6 inches and that changes since the previous survey in 2002 have been insignificant (Reference LTS-1000-4, WO 00558360-02 completed 10/15/04, and Ocean Survey drawings 04ES05864.1 and 04ES05864.2).
Worst-case weather data, already contained in the model, was used in the analysis . The UHS analysis effort also included updating the heat input load to include the effects of General Electric SIL 636 (Reference 3). The peak UHS inlet temperatures to the plant for 0" & 6" siltation levels are evaluated as follows:
Siltation Depth Starting UHS Temperature Peak UHS Inlet Temperature 0" 100 °F 101 .6'F (Table G.7.2 of Reference 2 6" 100 °F 101 .87 (Table G.7 .3 of Reference 2 Allowing the UHS initial temperature to increase 2°F (from 100 °F to 102 °F) would result in a corresponding 2°F increase in the peak temperature during accident conditions . This is reasonable and conservative based on the peak temperatures given above, meaning that during accident conditions the peak temperature of cooling water being supplied to safety-related components could be 104°F.
EC 356645, Rev. I Page 2 of 15 In this assessment a margin of +2'F is added to this peak UHS temperature. This margin could be used to account for things like lake temperature instrumentation uncertainty. For example, Circulating Water inlet temperature instrumentation, although not safety-related, is used to verify Tech Spec required limits . The CW Inlet temperature uncertainty has been determined in EC 336218 to be as much as t1 .8°F (Reference 4)
In summary, for accidents and transients involving a LOCA and postulated dike break the projected peak post-accident UHS temperature will be assessed as 104 °F + 2 °F for a peak temperature of 106 °F for CSCS system components . Beyond design basis events such as ATWS and SBO are evaluated for a 102 °F + 2 °F (for uncertainty, not post-accident increase) = 104 °F CSCS cooling water temperature.
Non-safety related components are reviewed from an operational standpoint only, because the main concern is with their effect on power operation. They are not credited to mitigate any design basis events . Most components are reliability related and are monitored for parameters such as temperature and pressure. These components can be described as self-limiting, that is, operations personnel will respond to alarms and conditions in accordance with approved plant procedures, including load curtailment per LOA-CW-101/201, as required . These components were evaluated in the Reference 1 Engineering Change (EC) 334017 at 104 °F. For these components the peak cooling water inlet temperature will correspond to the increased UHS temperature limit, i .e. 102 °F .
DETAILED EVALUATION :
Relevant UFSAR Rev. 15 Sections :
The specific UFSAR Sections related to non-safety-related systems are:
9.1.3 .2. 1 .1 ". . .the Spent Fuel Pool (SFP) cooling system safety design bases are . . . maintain the SFP water temperature . . . assumes a Service Water System water temperature of 100 °F ."
9.2.2 .2 "Maximum service water supply temperature is 100 °F ."
10.4.5.2 "The circulating water system supplies the main condenser with cooling water ranging from 32 °F to 100 °F maximum."
In addition, the UFSAR states the following about the safety-related UHS :
9.2 .6 .3 .2 . "The maximum temperature for cooling water supplied to the plant from the UHS during accident conditions is 102 °F."
Fig. 9.2-7 "UHS Lake Temperature Versus Time of Day" . This figure indicates that to ensure that the 102 °F limit is not exceeded during accident conditions the UHS temperature must be limited depending upon time of day and depth of siltation.
Function Performed by the Equipment CSCS Equipment Cooling Water System :
The safety function of the core standby cooling system (CSCS) is to circulate lake water from the ultimate heat sink for cooling of the residual heat removal
EC 356645, Rev . 1 Page 3 of 15 (RHR) heat exchangers, diesel-generator coolers, CSCS cubicle area cooling coils, RHR pump seal coolers, and low-pressure core spray (LPCS) pump motor cooling coils. This system also provides a source of emergency make up water for fuel pool cooling and also provides containment flooding water for post-accident recovery .
The UHS has the following safety functions: to provide sufficient water volume permitting a safe shutdown and cooldown of the station for 30 days with no water makeup - the maximum permissible water temperature supplied to the plant is taken as 1020F (post-accident). It is also designed to provide water for fire protection equipment and to withstand the most severe postulated natural phenomenon such as an earthquake .
Fuel Pool Cooling (FC) System :
The FC System is designed to prevent damage to the fuel elements contained in the fuel pool. Under normal operating conditions, the system is designed to maintain a water level of approximately 22 feet above the top of the spent fuel pool storage racks. The FC System also maintains the fuel pool temperature at or below a limit of 140°F under a maximum normal heat load (during refueling) using service water (cooling water) temperature of 100°F.
Service Water (WS) System :
The service water system removes heat from various equipment in the turbine building, reactor building, auxiliary building, service building, and radwaste facility during normal plant conditions, shutdown, and abnormal plant conditions when offsite power is available. The service water system removes the heat rejected by the reactor building closed cooling water and turbine building closed cooling water systems. It is also designed to supply strained cooling lake water to the radwaste facilities, screen wash, clean gland water, and to serve as a back up to the fire protection system . The service water system provides a reliable source of cooling water for station auxiliaries that are nonessential to the safe shutdown of the station during or following a design-basis LOCA .
Circulating Water (CW) System :
The purpose of the circulating water system is to remove the heat rejected from the main condenser. The circulating water system is designed to convey water between the main condenser and the cooling lake. The circulating water system is not required to effect or support safe shutdown of the reactor or to perform in the operation of reactor safety features .
Evaluation of Safety-Related Equipment:
Safety-related equipment is required to safely shutdown the plant and maintain cooling for 30 days assuming a LOCA and simultaneous dike failure (Reg. Guide 1 .27/UFSAR). The LaSalle County Lake serves as the water supply for the service water system and the ultimate heat sink (UHS). The safety-related heat exchangers have been evaluated for a cooling water inlet temperature of 106°F. The existing computer calculation models for most safety-related heat
EC 356645, Rev. 1 Page 4 of 15 exchangers were utilized for this analysis . Other safety-related heat exchangers, which use the CSCS water, are addressed as well below :
RHR Heat Exchangers (E12-BOOIA/B)
A review of the RHR Heat Exchangers concludes that they are in good condition. They have no material condition issues that would impair the ability of the components to support a change of the maximum inlet temperature from 104°F to 106°F. (EC 355042, Reference 27)
An assessment of RHR Heat Exchanger performance in the Containment Cooling mode was made with 106°F inlet service water (cooling water) (See Attachment A). The approved heat exchanger computer model (Cale. No.97-201) was used . The assessment found that with an inlet cooling water temperature of 106°F the heat rejection capacity of the RHR heat exchangers was approximately 172 E06 Btu/hr, which exceeds the required heat rejection rate of 163 .1 E06 Btu/hr (Ref. 16) . Additionally, several conservatisms were used in the assessment, including (1) the model assumes that 5% of the heat exchanger tubes are plugged. Currently, the maximum number of tubes plugged in any of the RHR heat exchangers are less than this amount (Per Ref.
27, the maximum number of tubes plugged is 29 in the 2A RHR Ht. Ex., this is less than 5% of 1063 total tubes or 53 tubes), and (2) the overall fouling factor used in the assessment is greater than that actually determined from the latest RHR heat exchanger performance testing for the Generic Letter 89-13 Program (NDIT LS-1154 and Calc . L-002571, ECs 340686, 350219) . The highest value of fouling based on testing, including uncertainties, is .00105, and a value of .0013 was used in the assessment.
An assessment of RHR Heat Exchanger capability for normal shutdown was also performed for an inlet service water temperature of 106 °F. The design heat rejection capacity for normal shutdown is approximately 42 E06-Btu/hr . The approved heat exchanger computer model referenced above was also used in this assessment . The design case indicates an inlet water temperature for the shutdown cooling flow from the reactor vessel of 120 °F which is based on an inlet service water temperature of 90 °F. For an inlet temperature of 106 °F, the heat rejection capability will be reduced to approximately 22EO6 BTU/hr per RHR Hx train. The shutdown temperature can still be obtained ; however, the time period required will be longer. An option available to plant operators depending on the plant conditions is to utilize both RHR heat exchanger trains, this will more than accommodate the design normal shutdown heat load . The normal shutdown cooling function is not safety related and the impact of the increased cooling time and its impact on plant availability is not a safety concern (Ref. 35).
These temperatures are well below the containment cooling mode values given previously . Thus the containment cooling mode effect on the heat exchanger is bounding.
Post LOCA Suppression Pool Temperature Analysis :
Since the containment cooling mode heat rejection capability of the RHR Heat Exchanger exceeds the required heat rejection, there will be no impact on the LaSalle suppression pool temperature response following a LOCA . In other words, the post LOCA peak suppression pool temperature (196.1 °F at 102% of uprated reactor thermal power per UFSAR Section 6.2.2 .3 .5) even with a higher inlet service water temperature of 106°F will still be well below the suppression pool temperature NPSH limit for the ECCS pumps of 212°F.
Due to the expected performance of the RHR heat exchanger, other events that utilize the RHR heat exchangers for cooling would be expected to have the same results, i.e. since the heat removal capacity of the RHR heat exchanger is maintained, an increased (106 °F) CSCS cooling water temperature will not impact suppression pool temperature.
EC 356645, Rev. 1 Page 5 of 15 RHR Pump Seal Coolers The RHR Pump Seal Coolers on both Units 1 and 2 were replaced with new units during LIF35 and L2R07. There is margin between the most current measured cooling water flows (ranging from - 11 gpm to 30 gpm per Ref. 33) and the minimum required flow 6.5 gpm (Calculation L-002404). The coolers are flow tested quarterly and cleaned before flows drop below the minimum required . All four coolers have been flow tested satisfactorily since late April 2005 (Ref. 3 3).
The tube side design inlet water temperature is 360 °F (max .) at a flow of 2 gpm; this flow stream is cooled to 250 °F to cool the pump seals. This operating condition is during normal shutdown conditions only. The Ref. 8 calculation indicates the seal cooler presently is capable of meeting the pump seal limit on exit temperature of 250 °F with the 5 gpm shell side cooling water design flow (equates to the minimum required flow of 6.5 gpm during normal non-accident conditions) at 104 °F with approximately 50% margin in heat removal capability . This indicates an adequate margin currently exists in the coolers to accommodate an increase in inlet service water temperature to 106 °F.
1(2) LPCS Motor Coolers [1(2)E21-0001]
These heat exchangers are a shell and coiled tube type, designed to cool lubricating oil surrounding the three sections of bearing in the LPCS motor. Based on a review of bearing temperature data for the months of June, July and August 2001 the maximum bearing temperatures experienced were at least 27 degrees below the corresponding alarm set points (see Ref. 1, Attachment G). These pumps were operated several different times throughout the summer. These periods of operation were short duration runs, however from a review of the data they were long enough in nature to demonstrate the maximum running bearing temperatures (see Reference 1, Attachment B) . The maximum service water temperature experienced during the summer of 2001 was 98 .5°F on 7/24/01 . Therefore, increasing the service water temperature by 7.5°F (up to 106°F), then correlating a 7.5 degree increase in bearing temperature will not challenge the alarm set points or operability of these components . The service water flow rates have met or exceeded the required flow rates based on current surveillances . They have no material condition issues that would impair the ability of the components to support a change of the maximum inlet temperature from 104 °F to 106 °F. (Based on Ref. 27, this evaluation is still valid) .
Diesel Generator Heat Exchangers The Diesel Generator Heat Exchangers (0, 1A, 1B, 2A, and 2B) have no material condition issues that would impair the ability of the components to support a change of the maximum CSCS inlet temperature from 104°F to 106°F. No tubes are currently plugged on these heat exchangers and their material condition is considered good. (Based on the Ref. 27 EC this assessment of material condition is still valid) .
An assessment of the DG Heat Exchangers performance was made with 106°F inlet service water (See Attachments B & C) . The approved heat exchanger computer models (Cale. Nos.97-195 &
97-197) were utilized for this assessment .
The assessment of the Div. 3 HPCS Diesel heat exchanger determined that with an inlet cooling water temperature of 106 °F, the heat rejection capability of the heat exchanger is approximately 8.05 E06 Btu/hr, exceeding the design heat rejection rate of 7 .8 E06 Btu/hr .
EC 356645, Rev. 1 Page 6 of 15 The assessment of the Div. 1 & 2 EDG heat exchangers determined that with an inlet cooling water temperature of 106 °F, the heat rejection capability of each of these heat exchangers is approximately 9.12 E06 Btu/hr, exceeding the design heat rejection rate of 8 .6 E06 Btu/hr.
The fouling factors used in the evaluation were based on current design basis values that are greater than twice those measured in the most recent G.L . 89-13 testing of these heat exchangers .
This fouling factor statement is still correct based on as-tested data documented in ECs 352723 and 352877 .
ECCS Corner Room Coolers (VYOI/2/3/4A)
Assessments were performed on all of the ECCS Corner Room Coolers at a service water inlet temperature of 106 °F (See Attachments D - G of EC 337958) using existing computer models with no tubes plugged (Reference 27). The entering air temperature to the coolers used is the current design basis of 148°F. The assessments demonstrated that at design fouling conditions, the VYOIA, 03A & 04A room coolers all had positive margins of at least 8% over the required heat rejection capability. The 1VY04A Cooler was noted, based on Ref. 37, to have a degraded air flow rate approximately 2% below test acceptance criteria . The above stated evaluations and margins are based on including a 10% air flow rate reduction for the VY03A and VY04A coolers.
This reduction in air flow bounds the actual measured reduction from a heat rejection capability standpoint .
Additionally, the cooler air flow rates used as input for the computer models were reviewed based on the changes in heat rejection caused by the higher inlet cooling water temperature. Sensitivity computer runs were performed to assess the impact of changes in coil inlet volumetric air flow due to small changes in air density. These effects were found to be negligible, (i.e. less than 1%
impact on heat rejection capability).
For the VY02A HPCS Corner Room cooler the current design computer model contained a 5%
tube plugging margin . Since no tubes are currently plugged, this cooler was evaluated at its current condition with all tubes in service. The HPCS corner room temperature is predicted to be 150 °F, when the inlet cooling water is at or near its peak of 106 °F (as noted in the section on EQ below this is for a short duration time period). This is the same peak room temperature predicted in the Reference 1 EC. Tthe potential Environmental Qualification (EQ) effects are addressed in the referenced EC and repeated in the section below on EQ. With the above input, the heat removal margin in the 1(2)VY02A coolers is approximately 1 .5%. Though not specifically evaluated in this assessment, there is additional margin available in the VY02A coolers.
Surveillance data indicates that both units' coolers have airflows approximately 5% higher than the design value. Experience has shown that this would result in approximately 3-4% of additional heat removal margin.
Summary of Specific Inputs used in the Computer Models to Assess Heat Exchanger Performance :
A summary table listing certain inputs and assumptions used in the detailed computer model assessment of the various heat exchangers and coolers discussed above is provided as Attachment M to this EC .
Environmental Qualification of Equipment:
The VY Comer Room cooler for the HPCS room has been analyzed to accommodate the HPCS room heat load . The UHS analysis determined that the peak cooling water inlet temperature occurs during the first 24-hours following the failure of the dike . This cooling water inlet
EC 356645, Rev. 1 Page 7 of 15 temperature has been increased to 106°F to add margin for analysis purposes . At the 106°F inlet cooling water temperature the room is calculated to increase to 150°F . This room temperature has been evaluated as acceptable to the EQ components in this room under the Reference 1 EC. It should be noted this peak occurs for approximately 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> during the first 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (per Reference 2, Figure G.7.1). Although not credited in this assessment, a qualitative review of the EQ data concluded that the equipment in the VY cooler room would likely be acceptable to temperatures of at least 160 °F for the 6 hour6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> period .
Additional CSCS System Issues :
Existing calculations for CSCS System pressure losses and NPSH were based on 100°F (Reference 7). An increase in inlet water temperature from 100°F to 104°F was evaluated in the Reference 1 EC 334017 . An additional 2 °F increase to 106 °F will not change the conclusions of that evaluation . The change results in a negligible change in water density and saturation pressure, two key parameters affecting system pressure losses and NPSH. Thus it can be concluded that the temperature increase has negligible impact on these parameters.
Changes in room ambient conditions from piping heat losses due to a 2 °F increase in cooling water temperature are judged to be negligible, given factors such as diurnal reductions in the peak UHS temperature and that most of the CSCS cooling water piping is insulated.
Heat Exchanger Fouling :
The short term operating periods anticipated for the higher cooling water inlet temperatures are not expected to significantly increase fouling in the heat exchangers evaluated. The plant's chemical feed injection system is used during normal plant operation to control lake water chemistry and minimize the potential for scaling of associated heat exchangers . One indicator of fouling resistance is main condenser performance. The condenser is being continuously subjected to heat loading and the higher lake temperatures, whereas most of the safety-related heat exchangers are not. The thermal performance engineer of System Engineering regularly monitors condenser performance. Significant increases in fouling will be detected by trending any changes in condenser performance.
Non Safety Related Equipment:
Fuel Pool Cooling (FC) Heat Exchangers The station is equipped with two (100% capacity) Fuel Pool Cooling (FC) Heat Exchangers per unit . The original FC heat exchanger heat removal capacity was 14 .5 E06 Btu/hr at a service water (cooling water) inlet design temperature of 95 °F and a 120 °F fuel pool temperature. As part of a 5% power uprate, the FC system safety design basis fuel pool temperature was changed to 140 °F at a service water (WS) inlet temperature of 100 °F (as given in the UFSAR Section 9 .1 .3 .2.1 .1).
In support of this evaluation, an assessment of FC heat exchanger performance, based on a conservative cooling water inlet temperature of 106 °F, was performed. The heat rejection capacity at a normal operating fuel pool temperature of 140 °F is estimated to be 23 .86 E06 Btu/hr with 1% (11) of the tubes plugged (See Attachment 1). None of the FC heat exchangers have any tube(s) plugged (Ref. 27). Based on Ref. 27, a bounding estimate for each unit's fuel pool heat load is 6.8 E06 Btu/hr. Thus, it can be concluded that the bulk fuel pool temperature can be maintained at or below 140°F with 106°F inlet service water (cooling water) .
EC 356645, Rev. 1 Page 8 of 15 An evaluation of the FC system's ability to cope with an emergency full reactor core off-load was also made . The Standard Review Plan Section 9.1 .3 "Spent Fuel Cooling and Cleanup System" requires for the case of an (abnormal) emergency full core off-load, the fuel pool shall be maintained less than the boiling point and level maintained . The higher service water temperature will not impact the ability to maintain fuel pool level as this is accomplished with the FC portion of the system . UFSAR Table 9.1-6 indicates a peak temperature for an emergency full core off-load of 155 .3 °F. The heat rejection capacity for these "emergency off-load" conditions at a fuel pool temperature of 155.3 °F and a service water inlet temperature of 106 °F is estimated to be 65 .5 E06 Btu/hr (See Attachment J using both heat exchangers and pumps).
The maximum heat generation rate for the abnormal (emergency) core off-load case is 59 .7 E06 Btu/hr (UFSAR Table 9 .1-6). Thus, it can be concluded that the bulk fuel pool temperature can be maintained at or below 155 .3 °F with 106 °F inlet service water (cooling water) even under these abnormal conditions . Additionally, the "B" RHR Heat Exchanger and pump is available as a backup to the FC System . The B-RHR heat exchanger heat rejection capacity is much greater since it has over 2 .8 times the effective heat transfer area as the FC heat exchanger (Reference the effective areas shown in Attachments A & I) .
Other Non Safety Related Components :
Non-safety related components were reviewed from an operational standpoint only, because the main concern is with their effect on power operation. They are not credited to mitigate any design basis events . Most components are reliability related and are monitored for parameters such as temperature and pressure. These components can be described as self-limiting, that is, operations personnel will respond to alarms and conditions in accordance with approved plant procedures, including load curtailment per LOA-CW 101/201, as required. These components could be subjected to the new temporary lake temperature (i.e. 102 °F) . These components were evaluated in EC 334017 (Reference 1) for an inlet cooling water temperature of 104 . The main components are listed below and the discussion from the Reference 1 EC is repeated for completeness :
1(2) Main Condenser [1(2)CDOIA]
The main condensers use lake water to condense steam returning from the turbine. The consequence of elevated lake temperature above the currently indicated circulating water (CW) system maximum of 100°F occurs in condenser backpressure and condensate temperature. If needed, Operations will execute load curtailment per LOA-CW-101, or -201 to maintain these parameters below their respective limits .
The CW system piping has been reviewed for a temperature of 115 - 120 °F (Reference NDIT LS-1111). This temperature does not impact the CW system piping, supports, or expansion joints . Thus, it is concluded that the condenser can tolerate a maximum lake inlet temperature of 104°F, however unit load curtailment may be necessary due to turbine backpressure limitations.
1(2) RBCCW Heat Exchanger [0(1)(2)WRO1A/AA/AB]
The Reactor Building Closed Cooling Water Heat Exchangers remove heat from a closed cooling water loop supplied to heat exchangers within the Reactor Building . An engineering evaluation was previously performed under NDIT# LS-1106, Upgrade 0. This evaluation concluded "an increase of WS inlet temperature to 103°F will not adversely affect the ability of the WR (or RBCCW) system to provide adequate cooling to its associated system loads" . A review of this engineering evaluation identified more than enough margin to account for a 1°F increase above
EC 356645, Rev. 1 Page 9 of 15 what was previously reviewed hence enveloping a WS inlet temperature of 104°F without invalidating the conclusion .
1(2) TBCCW Heat Exchanger [1(2)WTOIAA/AB]
The Turbine Building Closed Cooling Water Heat Exchangers remove heat from a closed cooling water loop supplied to heat exchangers within the Turbine Building . An engineering evaluation was previously performed under NDIT# LS-1107, Upgrade 0. This evaluation concluded "an increase of WS inlet temperature to 103°F will not adversely affect the ability of the WT (or TBCCW) system to provide adequate cooling to its associated system loads" . A review of this engineering evaluation determined there is more than enough margin to account for a 1°F increase above what was previously reviewed hence enveloping a WS inlet temperature of 104°F without invalidating the conclusion . Per EC 341508, Ref. 9, the only change in tube plugging is with the 2B Heat Exchanger, which has less than 30 tubes plugged per Ref. 27 . Based on the total number of tubes being 772, this represents approximately 4% of the tubes being plugged. The evaluation in NDIT LS-1107 listed above concludes the TBCCW outlet temperature from this heat exchanger leads the service water inlet temperature by 2 °F . A 104 °F inlet WS temperature implies that the TBCCW outlet temperature would be projected to be approximately 106 °F .
There is still 4 °F margin up to the 110 °F TBCCW maximum supply temperature. The 4%
reduction in number of available tubes has not significantly affected TBCCW Heat Exchanger performance, based on Reference 9 . Thus, the TBCCW supply temperature design limit of 110
°F (NDIT LS-1107) will not be exceeded with a WS inlet temperature of 104 °F.
Iso-Phase Bus Duct Coolers (cooled by the WT system)
It should be noted that operational experience has shown that the Iso-phase bus duct coolers may experience elevated temperatures above their design maximums under a conservative set of weather and equipment conditions (95°F Air Temp ., No Wind, Sunny, 104°F WS inlet, 1124 MW, 1 fan in operation). To mitigate these conditions and avoid exceeding the 167°F maximum design temperature, the Ref. 28 bus duct high temperature alarm response procedure requires the start of supplemental external bus duct cooling per LOP-GA-02 if the duct temperature reaches 167 °F.
1(2) Turbine Oil Coolers [1(2)TOOIAA/AB]
The Turbine Oil coolers are designed to maintain turbine lube oil at 110 - 120°F. Under normal operating conditions, one cooler is in service with the other available as additional cooling needs warrant (see Ref. 1, Attachment E, GE Main Oil Coolers). It has been determined that the data used in the Reference 1 EC was taken prior to control system modifications which provided much improved operation of the service water temperature control valve. Based on plant walkdowns by System Engineering on 7/17/02 and 7/22/04, when cooling water inlet temperature was approximately 92 °F, the temperature control valve was approximately 20 - 25% open on both units. Based on this information and the lack of any lube oil high temperature concerns during the high lake temperatures of early August 2005, the turbine lube oil temperature is not expected to be a challenge to operation of the plant up to WS temperatures of 104 °F.
1(2) Primary Containment Drywell Ventilation Chiller 1(2)A/1(2)B/1(2)C [1(2)VP02AA/AB, 1(2)VP16A]
Technical Specification 3 .6.1 .5 requires the Drywell air temperature to not exceed 135°F. The design WS inlet for each chiller is 100°F. Under normal operation, one of the AA and AB units are in service with the VP16A serving as a backup to provide additional cooling. This additional margin provided by the backup chiller would provide ample cooling to maintain drywell air
EC 356645, Rev . 1 Page 10 of 15 temperature below 135°F. Therefore, this equipment is expected to accommodate a 104 °F inlet WS temperature and be able to maintain acceptable drywell temperature.
Additional Turbine/Generator Related Components :
The following additional components were evaluated in EC 334017 (Reference 1) and found to be able to accommodate an inlet cooling water temperature of 104 °F:
1(2) Alternator Exciter Cooler [ I (2)MPO I A]
1(2) Hydrogen Generator Cooler [1(2)TGOIAA/AB/AC/AD]
1(2) Stator Coolers [I (2)TG02AA/AB]
Temperature data cited in the Reference 1 EC demonstrates that the Stator Cooler will be close to the inlet high temperature alarm setpoint of 47 °C (116.6 °F). The Ref. 29 alarm response procedure requires that generator load be reduced as necessary to avoid exceeding the maximum limit on stator coolant return temperature.
Miscellaneous Considerations :
Lake make-up and blowdown are negligibly affected by this change . The make-up water is from the Illinois River to the cooling lake and thus is not affected by lake temperature. The blow down system discharges water from the lake, however the discharge is outside the UHS portion of the lake . Blowdown temperatures are addressed in the Summer Readiness Plan by the Chemistry Department (see Ref. 32) .
The FP fire water pumps have been evaluated for the inlet temperature of 100°F. The specification for the pumps (J-2570) specified an operating temperature range of 32-100°F. The increase in inlet water temperature from 100 °F to 104°F results in a negligible change in water density and saturation pressure, two key parameters affecting system pressure losses and NPSH.
Thus it can be concluded that the temperature increase has negligible impact on fire protection system performance or available NPSH.
To maintain the fire pump diesel engine jacket water temperature within the operating procedure and monthly surveillance normal band of 165 °F to 200 °F, the inlet cooling water pressure can be adjusted in the range from 5 to 55 psig to accommodate an increase in UHS cooling water temperature from 100 °F to 104 °F . If the jacket water temperature and/or cooling water pressure to the engine heat exchanger cannot be maintained in the normal band, procedures require the adjustment of the Engine Cooling Water Supply Regulating Valve or Engine Cooling Water Supply Regulator Bypass Downstream Stop Valve.
Based on information in the Ref. 34 vendor manual, the most temperature limiting components in the fire pump are those of soft materials such as natural rubber and synthetic materials. The general temperature limit provided for bearings of these materials is 125 °F, in excess of the peak UHS water temperature. Gaskets would have similar or higher limits .
EVALUATION OF ACCIDENT ANALYSIS (Refer to Attachments K & L)
EC 356645, Rev. 1 Page 1 1 of 15 LOCA ANALYSIS Short Term The short term LOCA Peak Cladding Temperature (PCT) calculation is independent of Lake Temperature or service water temperature. The ECCS fluid temperature assumed in the analysis is based on a conservative suppression pool temperature. Since the PCT occurs very early in the accident and a conservative ECCS fluid temperature is used, a higher lake or service water temperature will not change the PCT calculation. The calculated results to meet the 10 CFR 50 .46 criteria will not change .
Long Term The post LOCH long term cooling required by 10 CFR 50.46 will also be acceptable with an increase in the lake / service water temperature. The lower 2/3 of the core will remain covered. Also, provided that at least 1 core spray system is available long-term, the upper third of the core will remain wetted by the core spray water, which will prevent further cladding perforation or metal-water reaction . As long as there is water in the suppression pool for core spray and 2/3 height coverage is maintained, higher lake/service water temperature of 106°F will have no significant impact upon LOCA long term cooling.
CONTAINMENT ANALYSIS The short-term containment response is not affected by lake or service water temperatures . The short-term response is primarily driven by the mass and energy release and containment parameters . These are independent of lake and service water temperature .
An increase in the lake and service water temperature could have an impact on the long term containment response to a LOCA accident. The RHR service water temperature assumed in the suppression pool temperature analyses is 104 °F . The current analysis assumes 104 °F for the duration of the analysis . For the purpose of this evaluation it is postulated that the RHR service water temperature will increase as the ultimate heat sink is increasing to a postulated 106 °F (assumes the unlikely failure of the dike). However, even assuming a 106 °F RHR service water temperature for the duration of the event there will not be a significant impact upon the results.
Sensitivity studies, Attachments K & L, were performed with a suppression pool model for the long term heat up analysis with the RHR service water temperature increased from 100 °F to 103
°F. This sensitivity analysis showed that there would be a 2 - 3 °F increase in the peak pool temperature response . The corresponding increase in the peak pool temperature response for an RHR service water temperature of 106°F is a 4 - 6 °F increase . The current post power uprate LaSalle peak suppression pool temperature has been evaluated to be 196.1 °F (Ref. 23 and UFSAR Section 6.2.2.3 .5). Since the post-LOCA suppression pool temperature limit is 212 °F, the increase in service water temperature to 106 °F would result in acceptable margins to the limit and the containment/ ECCS equipment will perform the required safety functions. It is expected that in the long term (after the peak suppression pool temperature is mitigated), both RHR heat exchanger trains could be used to keep suppression pool temperature profile within the current analysis results.
Other long-term containment heat up analyses to show compliance to NUREG-0783 (Suppression Pool Temperature Limits for BWR Containment), would result in a similar change as discussed above. These analyses are primarily performed to verify acceptable safety-relief valve quencher performance. Power uprate calculations have been performed for LaSalle and show that the peak
EC 356645, Rev. 1 Page 1 2 of 15 suppression pool temperature (bulk) is 190.7 °F for the SRV discharge case (Ref. 23). The acceptance limit for isolation scram containment analyses has been established at 206 °F (Ref.
23). The potential 4 - 6 °F increase due to a higher RHR service water temperature would still provide acceptable margins to the limit and the containment will perform the required safety function . It is expected as in the LOCA assessment above, both RHR heat exchanger trains could be used to keep suppression pool temperature profile within the current analysis results.
TRANSIENT ANALYSIS - UFSAR CHAPTER 5.2 AND 15 UFSAR Section 15 .2.9 addresses the Failure of RHR Shutdown Cooling. This event assumes the operation of RHR for suppression pool cooling. The revised power uprate analysis (Ref. 23) assumes 100°F for the duration of the analysis, and an RHR Heat Exchanger heat transfer coefficient K value of 377 Btu/sec-°F . No credit is taken for passive structural heat sinks in the drywell and suppression chamber (airspace and pool) to conservatively maximize the calculated peak suppression pool temperature. The analysis results in a calculated peak suppression pool temperature of 210 .4 °F for this event. However, Ref. 24 demonstrates that the current RHR HX K value is at least 416.6 Btu/sec-°F at pool temperatures of 170 °F to 212 °F with an inlet service water temperature of 104 °F . At the 104 °F inlet temperature and the higher K value, the calculated peak suppression pool temperature in Ref. 24 decreased by 5 .5 °F from that calculated for the lower K value. Use of the higher current K value in the Ref. 23 would therefore more than offset the increase in peak pool temperature due to the 4 degree increase in the inlet service water temperature to 104°F (102°F + 2 °F margin). Since the suppression pool temperature limit for this event is 212°F, the increase in service water temperature would result in acceptable margins to the limit and the containment and RHR shutdown cooling will perform the required safety functions. It is expected that in the long term (after the peak suppression pool temperature is mitigated), both RHR heat exchanger trains could be used to keep suppression pool temperature profile within the current analysis results.
The balance of the Chapter 15 transient analysis, including Chapter 5.2 ASME vessel overpressurization, are short-term analyses of postulated events to verify core response, to set the fuel thermal limits, and to verify acceptable vessel overpressurization results. Most of these events either result in a scram or result in no significant change in thermal power. Since these events are only analyzed for the short-term response, there is no dependency on the lake temperature or service water temperature for the consequences of these events .
ATWS ANALYSIS - UFSAR SECTION 15.8 The ATWS analysis described in UFSAR Section 15 .8 is a beyond design basis event. Analyses have been performed to show that with the installation of the SLCS, ARI and ATWS RPT systems that acceptable ATWS results could be attained . GE performed many of these generic calculations in NEDE-24222. In these calculations, GE stated "Due to the extremely low probability of the occurrence of an ATWS, nominal parameters and initial conditions have been used in the analyses . This is consistent with the NRC staff request." Therefore, it is not required to use a design maximum value for the ATWS analysis . However, it can be explicitly addressed as discussed below.
Power uprate ATWS analysis has been performed for LaSalle. This analysis assumed a service water temperature of 100 °F and a peak suppression pool temperature of 204 °F was calculated (ref. 6). A bounding assessment assumed that the peak suppression pool temperature would increase by the amount of service water temperature increase. Therefore, with a 4 °F increase to the suppression pool temperature (2°F due to the increased service water temperature and 2°F due to uncertainties), the peak temperature is not expected to exceed 212°F, which is the acceptance limit. It is expected that in the long term (after the peak suppression pool temperature is
EC 356645, Rev. 1 Page 1 3 of 15 mitigated), both RHR heat exchanger trains could be used to keep suppression pool temperature profile within the current analysis results . Based on the discussion above, the ATWS analysis is acceptable with elevated lake and service water temperatures .
STATION BLACKOUT ANALYSIS - UFSAR SECTION 15 .9 The Station Blackout (SBO) analysis discussed in UFSAR Section 15 .9 is a beyond design basis event. This event requires the use of the RHR heat exchangers to remove the decay heat from the suppression pool. The Station Blackout event analysis is performed assuming a complete loss of AC for a four hour period. The coping analysis assumes operation of the RCIC and/or the HPCS system, but without crediting the HPCS diesel as an alternate AC source . Postulating a service water temperature of 104 °F (102°F + 2 °F margin) over the entire duration of the event will not significantly affect the peak suppression pool/drywell temperatures predicted in this event since no cooling is available until after AC power is restored . The effect of 104 °F service water temperature was evaluated in the Ref. 1 EC and it was shown that the RHR Heat Exchanger capability is still maintained at a 104 °F inlet cooling water temperature. Consequently, the increased cooling water temperature will have a negligible impact on this, since the cooling effectiveness of the RHR heat exchangers is maintained .
In addition, it should be noted that the SBO analysis was intended to be a best-estimate analysis, based on nominal decay heat values and typical system performance. Therefore it can be argued from a licensing basis that the analysis does not have to bound all postulated ranges of parameters .
IOCFR50 APPENDIX R FIRE EVENT Modeling assumptions for Appendix R analyses are similar to those for SBO. However, since the Appendix R event duration is much shorter than the assumed duration for SBO, the temperature response of the suppression pool is more limiting for the SBO event. (Ref. 36 .)
GE SIL 636 General Electric (GE) has issued Services Information Letter (SIL) 636, Rev 1, which identifies that analyses that use decay heat curves from ANSI/ANS-5 .1-1979 may be affected by additional actinides and activation products. Individually these actinides and activation products are negligible, but collectively they could have a non-negligible impact . For decay heat calculations that use a 2-sigma uncertainty adder, the effect upon decay heat is offset by the uncertainty up to 108 seconds. The specific concern identified in this SIL was evaluated in Operability Evaluation OEO1-012 (which has since been closed) . The effects of the change on decay heat have been included in the Reference 2 calculation for peak UHS temperature. The RHR Heat Exchanger was evaluated in the Reference 1 EC for these heat loads and was shown to meet or exceed its design basis heat rejection capability . The effects of the change in decay heat on the Fuel Pool Cooling and Cleanup System were addressed in Ref. 26. The effects of these changes in decay heat are negligible .
SUMMARY
/CONCLUSION :
Per the above discussion and referenced documents, it has been demonstrated that increasing the maximum allowable temperature of cooling water supplied to the plant from the lake from 100°F to 102°F will have no adverse affect on the safety-related plant heat exchangers or the heat loads they serve. The design requirements of these interfacing components (heat exchangers) have been reviewed and a determination made that thermal margin exists to allow for the increased service water inlet temperature, while maintaining an acceptable heat transfer capability.
