FC6896NP Revision 1 Page H of 60 1.0 PURPOSE This analysis determines the overall calorimetric uncertainty associated with plant computer application XC105.
The analysis accounts for the instrument uncertainties associated with the independent variables that have the largest impact on the calculation of calorimetric power.
These variables are:
Feedwater Flow Feedwater Temperature Steam Generator Pressure Steam Generator Moisture Carryover Steam Generator Blowdown Flow Steam Generator Blowdown Temperature This analysis combines the individual instrument uncertainties associated with the independent variables to determine the overall calorimetric uncertainty.
The individual contributions to the power uncertainty are combined using a statistical summation to determine the total power measurement uncertainty.
This approach is consistent with the methods described in ANSI/ISA-67.04.01-2000, "Setpoints for Nuclear Safety-Related Instrumentation" (Reference 2.3)
This calculation is applicable for use with the CROSSFLOW ultrasonic feedwater flow measurement system.

6.0 CONCLUSION
S This calculation determined the calorimetric uncertainty based on an upgrade of feedwater flow and temperature instrumentation which is used for the XC105 calculation.
Allowable Uprate:
2%-0.3506% = 1.6494%
Based on this an uprate of 1.60% is acceptable and enveloped by this analysis.

LIC-03-0122 Attachment 5 Affidavit for Calorimetric Uncertainty Evaluation
PI, Integrated Services Proprietary Affidavit 1, Tim Leibel, depose and say that I am a Principal of PL Integrated Services LLC (PLIS), duly authorized to make this affidavit, and have reviewed or caused to have reviewed the information which is identified as proprietary and described below. I have personal knowledge of the criteria and procedures utilized by PLIS in designating information as a trade secret, privileged, or as confidential commercial or financial information.
This affidavit is submitted in conformance with the provisions of 10 CFR 2.790 of the Commission's regulations for withholding proprietary information. The information for which proprietary treatment is sought, and which document has been appropriately designated as proprietary, is Calculation Number FC-6896-P 'Secondary Calorimetric Uncertainty Analysis".
Pursuant to 10 CFR 2.790(b)(4) of the Commission's regulations, the following is furnished for consideration by the Commission in determining whether the information included in the document listed above should be withheld from public disclosure.
- 1. The information sought to be withheld from public disclosure is owned and has been held in confidence by PLIS. It consists of the information concerning the technical basis and implementation of a secondary calorimetric uncertainty analysis for the Fort Calhoun Station.
- 2.
The information consists of methodologies for the development and implementation of a secondary calorimetric uncertainty analysis, the application of which results in substantial competitive advantage to PLIS.
- 3.
The information is of a type customarily held in confidence by PLIS and not customarily disclosed to the public.
- 4.
The information is being transmitted to the Commission in confidence under the provisions of 10 CFR 2.790 with the understanding that it is to be received in confidence by the Commission.
- 5.
The information, to the best of my knowledge and belief, is not available in public sources, and any disclosure to third parties has been made pursuant to regulatory provisions or proprietary agreements that provide for maintenance of the information in confidence.
- 6.
Public disclosure of the information is likely to cause substantial harm to the competitive position of PLIS because:
- a.
A similar product or service is provided by competitors.
- b.
PLIS has invested substantial funds and engineering resources in the development of this information. A competitor would have to undergo similar expense in generating equivalent information.
- c.
The information consists of the technical basis and implementation of a secondary calorimetric uncertainty analysis for the Fort Calhoun Station, the application of which provides PLIS a competitive economic advantage. The availability of such information to competitors would enable them to design their product or service to better compete with PLIS, take marketing or other actions to improve their product's position or impair the position of PLIS product, and avoid developing similar technical analysis in support of their processes, methods or apparatus.
