1. Objective

The objective of the test program was to provide data [[]] The data were then used to verify a model

[[

Structural damping in the ANSYS finite element model is defined as 1% of criticaldamping for all frequencies, consistent with guidance given in NUREG-1.61 [1]. [[

]] With this information,verified by test results, [[ ]] could be specifiedand therefore provide a more realistic model of steam dryer stress response.

This test report summarizes the [[ ]] theory, the laboratorymeasurements, and the resulting [[

4. Instrumentation

[[

]] The data were recordedon a 16-bit data acquisition system calibrated to NIST traceable standards. [[

The accelerometer was mounted [[]] The

accelerometer was an Entran model EGA-10-/Z2. The accelerometer signal was amplified by anADC instrument amplifier and the system was calibrated against gravity. The amplifier outputwas connected to the data acquisition system.

An Omega PX302 pressure transducer []] The pressure transducer had a 200 psig range and was calibrated to NIST

traceable standards.

Air temperature was measured with a Type T thermocouple and Omega DP-41display.[R ]] Both the display

and thermocouple were calibrated to NIST traceable standards.

6. Test Procedure

For each test the instrumentation and test setup was first verified and recorded. [[

7. Test Results

Test data were entered into an Excel spreadsheet, [[

Sample fits are shown in Figure 7 [[ ]] and Figure 8 [[

]] The estimate is obtained byof the squares between the measured, ym(k), andminimizing the error defined

analytical, Ya(k), samples:as the sum

k2 2X = (ym (k) -ya (k))2

ki(7.3)

13


[[

The least squares fit is obtained by adjusting [[ ]] parameters: [[ ]] Theleast squares fit was selected as a method to systematize the reduction of the data arid, by usingall data points, [[ ]]

Two algorithms were considered to obtain the fit. The first was a 'brute force' method

Er]] a range. The parameter range is centered on the preliminary estimates obtained from the

previous manual curve fits and the range made sufficiently large to encompass the anticipatedfinal parameter values. In the innermost loop the error (7.3) is computed and the minimum valuerecorded together with the minimizing parameters. Upon termination of all [[ ]] do-loops anew estimate, q1, of the minimizing parameter set will be available. In order to refine the

estimate, the calculation is repeated using a narrower range centered about the optimizingparameters just obtained. This produces a refined estimate, q2. The calculation proceeds

through several iterations with each iteration shrinking the parameter search range thus zoomingin to the final optimal set of parameters, q*.

The second algorithm uses the conjugate gradient method to search for the minimum.The conjugate gradient implementation requires knowledge of the gradients, &I'/aq, which arecomputed analytically. The conjugate gradient search algorithm is much faster than the bruteforce approach (by approximately three orders of magnitude). To verify the correct performanceof the algorithm, the optimal fits, q*, were compared against the values obtained by the bruteforce approach for several cases. In all cases, good agreement (discrepancies occurred only inthe third significant figure) was achieved. Also, plots for several of the data sets comparing thesignal measurements against optimal curve fits were generated and examined to confirm goodfits. Several of these are shown in Figure 9 and Figure 10 [[

8. Data Analysis

[[I

1]

Comparing [[ ]] from theory to experimental measurement is importantfor application to steam dryer stress evaluation since it allows one to independently check thereliability of the theoretical predictions and also to adjust the theoretical prediction to both bettercorrelate with measured results and account for uncertainty in the test procedure. Here the ratio[]] is sought where (*)exp and (*)theory refer to experimental and theoretical

estimates. [[

CDI AFFIDAVIT

Attached is the CDI affidavit for the proprietary information contained in Enclosure 1.

40APXr Continuum Dynamics, Inc.(609) 538-0444 (609) 538-0464 fax 34 Lexington Avenue Ewing, NJ 08618-2302

AFFIDAVIT

I, Barbara Agans, being duly sworn, depose and state as follows:

I. I hold the position of Director, Business Administration of Continuum Dynamics, Inc.(hereinafter referred to as C.D.I.), and I am authorized to make the amended request for

withholding from the Public Record for C.D.I. Report No. 07-1IP "Dynamics of BWRSteam Dryer Components," Revision 1, prepared by Continuum Dynamics, Inc., datedNovember 2008. C.D.I. was the developer of the information sought to be withheld andthe author of the subject report, and the proprietary information contained therein for thefacility on whose docket the information was submitted to the Nuclear RegulatoryCommission (NRC). This Affidavit is submitted to the NRC pursuant lo 10 CFR2.390(a)(4) based on the fact that the attached information consists of trade secrets, andthat the NRC will receive the information under privilege and in confidence. Beingresponsible for the development of the information and report sought to be withheld, andbeing knowledgeable of the potential financial impacts of public disclosure of thedocuments I am in the best position to provide the required information and execute thisamended affidavit.

2. The subject information summarizes:

(a) a process or method, including supporting data and analysis, where prevention of

its use by competitors-constitutes a competitive advantage over other companies;

(b) information which, if used by a competitor, would reduce its expenditure ofresources or improve its competitive position in the design, manufactme,shipment, installation, assurance of quality, or licensing of a similar product;

3. The information sought to be withheld has been held in confidence by C.D.I. The subjectinformation has consistently been held in confidence, no public disclosure has been madeand it is not available to the public. All disclosures to third parties, which have beenlimited, have been made pursuant to the terms and conditions contained in non-disclosureagreements or other legally binding agreements which must be fully executed prior todisclosure.

4. The information is a type customarily held in confidence by C.D.I. and others in the fieldand there is a rational basis therefore. The subject information is a type, which C.D.I.considers trade secret and is held in confidence because it constitutes a source ofcompetitive advantage in the competition and performance of such work in the industry.Public disclosure of the information is likely to cause substantial harm to the owner of theinformation's competitive position and foreclose or reduce the availability of profit-making opportunities.

5. C.D.I. Report No. 07-IIP discloses that the dynamic condition of a particular BWRsteam dryer component is not very well modeled by the conventional practice in theindustry of assigning an accepted value to the component. The Report discloses ananalytical methodology, supported by tests and data, that provides a substantially bettermodel of the actual condition of the component. Recognition of the inaccuracy of theaccepted practice and knowing the improved value of C.D.I.'s methodology provides asignificant competitive advantage over competitors who do not appreciate itssignificance. This breakthrough was based on the insights and technical creativity ofC.D.I. employees and data developed and tests conducted by C.D.I. Based upon C.D.Ireview of the literature and C.D.I. knowledge of NRC filings by those not having accessto the subject report, the information sought to be withheld is not available in publicsources. The information in the document sought to be withheld has provided asignificant revenue stream for C.D.I. and has been demonstrated to have significanteconomic value, but only so long as the information is kept proprietary.

I declare under penalty of perjury that the foregoing affidavit and the matters stated therein aretrue and correct to the best of my knowledge, information and belief.

Executed on this 14 day of (, 2008.
