Letter from J. A. Bauer (Exelon Generation Company, LLC), "Additional Information Supporting the License Amendment Request to Technical Specification 3.7.3, "Ultimate Heat Sink," dated July 13, 2006 In Reference 1, Exelon Generation Company, LLC, (EGC), requested an amendment to Appendix A, Technical Specifications (TS), of Facility Operating License Nos. NPF-1 1 and NPF-18 for LaSalle County Station (LSCS) Units 1 and 2 respectively. Specifically, the proposed change increases the temperature limit of the cooling water supplied to the plant from the Core Standby Cooling System (CSCS) pond (i.e., the Ultimate Heat Sink (UHS)) from :5 100OF to :5 101.5 0 F. This increase is achieved by reducing the temperature measurement uncertainty by replacing the existing thermocouples with higher precision temperature measuring equipment. In Reference 2, the NRC requested additional information to complete the review of the proposed license amendment. In Reference 3, EGC provided the additional information requested.

CALCULATION NO. L-003230 Revision 000 PAGE 1 PURPOSE / OBJECTIVE CALCULATION PAGE 1.1 The purpose of this calculation is to evaluate the loop uncertainty for the CW Inlet Temperature Indication Loops. These are revised instrument loops that were implemented by EC359060 for Unit 1 and EC359114 for Unit 2. 1.2 These instrument loops provide Ultimate Heat Sink (UHS) temperature indication via the Plant Process Computer (PPC). These new loop configurations replaced the existing thermocouples 1(2)CW010/01 1 (the sensing elements for computer points F2855286) with new RTD temperature sensing elements and new temperature compensators (transmitters), and relocated the computer inputs to the appropriate Input/Output (1/0) analog input cards. 2 METHODOLOGY AND ACCEPTANCE CRITERIA 2.1 The methodology used for this calculation is based on NES-EEC-20

.04 "Analysis of Instrument Channel Setpoint Error and Instrument Loop Accuracy", Rev. 4 (Reference 5.1.2). Additionally, for calculating the average uncertainty using up to four indicating loops, the multiple test criterion of ASME PTC 19.1 (Ref. 5.1.4), Section 3.2 was used. 2.2 The instrumentation evaluated in this calculation provides indication (via the Plant Process Computer) for Ultimate Heat Sink Temperature. This is a non-safety indication loop, but the indication is used to verify the Technical Specification SR 3.7.3.1 is met. In accordance with Reference 5.1.2, Appendix D, a Level 3 evaluation is appropriate for this analysis. However, in response to questions during the NRC review of the License Amendment Request to increase the UHS temperature surveillance requirement value, this analysis will evaluate all uncertainty terms and determine the total uncertainty value using methodology consistent with safety-related indicating loops (Reference 5.1.2, Appendix D, Level 2). 2.3 Temperature, humidity and pressure errors, when available from the manufacturer, are to be evaluated with respect to the conditions specified in the station EQ Zones. If not provided, an evaluation must be made to ensure that the environmental conditions are bounded by the manufacturer's specified operational limits. If the environmental conditions are bounded, these error effects are considered to be included in the manufacturer's reference accuracy. 2.4 Published instrument vendor specifications are considered to be based on sufficiently large samples so that the probability and confidence level mess the 2a criteria, unless stated otherwise by the vendor (Reference 5.1.2, Appendix A, Section 8.0). 2.5 For normal error analysis, normal vibrations and seismic effects are considered negligible or capable of being calibrated out in accordance with Appendix I of Reference 5.1.2. 2.6 The calibration standard error is considered negligible

the calibration standard error (STD) is more accurate than the M&TE by a ratio of at least 4

1 (Reference 5.1.2, Appendix A, Section 5.1.4). 2.7 The insulation resistance error is considered negligible unless the instrumentation is expected to operate in an abnormal or harsh environment (Reference 5.1.2, Appendix A, Section 7.0). 2.8 Reference 5.1.2, Appendix I states that the effects of normal radiation are small and accounted for in the periodic calibration process. Outside of containment during normal operation, the uncertainty introduced by radiation effects on components is considered to be negligible. 3 ASSUMPTIONS AND LIMITATIONS

3.1 Evaluation

of M&TE errors for the digital multimeter is based on the assumption that the test equipment listed in Section 4.5 is used. 3.2 It is assumed that the calibration standard of the equipment utilized is more accurate than the M&TE equipment by a ratio of at least 4:1 such that the calibration standard errors can be considered CALCULATION PAGE CALCULATION NO. L-003230 Revision 000 PAGE NO. 4 of 14 negligible with respect to the M&TE specification per Section2.6. This is considered a reasonable assumption since M&TE equipment 4 certified to its required accuracy under laboratory conditions. 4 DESIGN INPUTS 4.1 The new instrument loops will consist of the following components

high accuracy RTD temperature elements, temperature transmitters, precision input resistors at the field input to the 1/0 card, and the D/A conversion in the PPC 1/0 equipment. The loop components evaluated in this document have the following specifications

4.1.1 New Minco RTDs; in the existing thermowells (replacing the existing thermocouples). The new RTDs have the following performance specifications (Ref. 5.4.1): Repeatability

+/-0.2 0 F [The RTDs are designed to EN60751 Class A specifications with high precision and repeatability requirements. Thus, this specification could be considered to be at a 36 confidence level. However, for conservatism, this specification will be used as a 26 value.] Drift: 10.1 OF/year (Ref. 5.4.3) [The study in Reference

5.5.3 shows

that RTDs are inherently stable, and after the first few months following installation RTDs attain a stable condition from which it may not drift sufficiently to exceed accuracy limits. RTD cross-calibration is performed to identify if an element has experienced significant drift. Although the RTDs; am not separately calibrated, for conservatism the vendor's drift value will be expanded using the loop calibration interval of 4 years (+ 1 year late factor).] 4.1.2 The resistance value equivalent to the temperature value of interest (101.5 0 F) for the RTDs was obtained from the Minco, calibration reports for the RTDs installed at LaSalle (Ref. 5.4.10). The highest of the four resistance values was 115.0135. . This value will be used to determine the M&TE error for the indicating loop (applied to Module 2). The change in resistance per 1 OF change in temperature (0.214YOF) was also obtained using the actual resistance values in the calibration reports for 101.5 0 F and =5 0 F. 4.1.3 New ifm@ efector600 TR2432 temperature transmitter modules. These new modules have the following performance specification (Ref.5.4.4, 5.4.5): Accuracy (includes drift): +/-0.54 0 F / 2 years `Temperature Drift': +/-0.1% of measured range/ 10 0 C [Note: Ref. 5.4.5 indicates that the accuracy specification includes drift error and is warranted to hold the accuracy and drift within the specified value for 2 years. It further states that testing is performed on 100% of the devices after production to verify conformance with these specifications. Therefore, these values are 36 confidence level. It also states that the accuracy specification includes the resolution error and electronic component drift, and that there are no other environmental influences that will affect the accuracy specification

.] 4.1.4 PPC 110 input card. The 1/0 input cards have the following performance specification (Ref.5.4.9): f2a) Accuracy: +/-0.025% of full scale (30OF to 120 0 F) 4.2 RTD extension wire has the identical conductor types as the RTD, and therefore there is no emf drop or change in conductor size at the point of connection on the RTD (Ref. 5.4.2).

The calibration procedures (Ref. 5.2.1 and 5.2.2) each specify that one loop will be calibrated using either the Fluke 45 OR the HP 34401 A. The other loop must be calibrated using the other DMM. 4.5.1 Reference Accuracy for the Fluke 45 (medium speed) on the 3000 range is: (+/- 0.05% reading + 2 LSD + 0.020) (Ref. 5.4.6) [2a] 4.5.2 Reference Accuracy for the H P 34401A on the 1 k9l range is: +/- (0.01% reading + 0.001% range) (Ref. 5.4.7) [2a] Temperature coefficient for the HP 34401A on the 1W range is (for OOC to 18 0 C and 28 0 C to 55 0 C): +/- (0.0006% of reading + 0.0001% of range /'C) (Ref. 5.4.7) [2(T] 4.6 LOCAL SERVICE ENVIRONMENTS (Ref. 5.5,2) [Note: Per reference 5.5.2, the no expected humidity this zone is 20 to 50% RH] 4.7 Calibration Tolerance The calibration tolerance for these indication loops is +/- 0.54 0 F.

The normal turbine building ambient temperature in the zone where the transmitter is installed varies from 83 0 F to 102 0 F(Ref. 5.5.2).

These assemblies will replace the existing head that is on the thermowell. This is due to not knowing how long the replacement probe would need to be. The drawing does not provide all of this information to determine the proper length. Lead time for these parts is also relatively short as compared to a special probe. 2. 1. Probe length is 15.6". This is the necessary length of the probe to fit in the thermowell and fit into the connection head. 2. The probe diameter is .25", but will fit in the thermowell without any reduction in performance. 3. Drift specifications on the 5852 sensor is listed as +/- .2 F per year, repeatability is also +/- .2 F. This specification assumes cycling throughout the full temperature range of the sensor, from - 50C to 260C. A smaller temperuture cycle will change the amount of drift.

Dear Vikram:

PA 19341 # # Nw 800-329-0436 0 vvtoozi This letter is in response to your concern about the specifications of the ifm efector TR2432 temperature sensor. The following points should clarify the questions that you had: " After production, 100% of the sensors are verified and tested to the specifications listed on our datasheet. " The analog accuracy specification of (+/- 0.54 0 F) already includes the analog resolution value of (0.1'F), and is inclusive of any electronic component drift. " The temperature drift specification is the electronic drift that occurs for every 10°C change in temperature that occurs in the application. This drift is in addition to the accuracy specification. " There are no other environmental influences that will affect the accuracy specification. " These sensors have a warranty period of 2 years. Phase contact me if you have any further questions, or if you require any additional information.
