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

- 7. Test Results Test data were entered into an Excel spreadsheet, ((
Sample fits are shown in Figure 7 ((

The estimate is obtained by of the squares between the measured, ym(k), and minimizing the error defined analytical, Ya(k), samples:

(ym (k) -ya (k))2 ki (7.3) 13

((
The least squares fit is obtained by adjusting ((
)) parameters: ((
)) The least squares fit was selected as a method to systematize the reduction of the data arid, by using all 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 anticipated final parameter values. In the innermost loop the error (7.3) is computed and the minimum value recorded together with the minimizing parameters. Upon termination of all ((
)) do-loops a new 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 optimizing parameters just obtained.
This produces a refined estimate, q2.
The calculation proceeds through several iterations with each iteration shrinking the parameter search range thus zooming in 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 are computed analytically. The conjugate gradient search algorithm is much faster than the brute force approach (by approximately three orders of magnitude). To verify the correct performance of the algorithm, the optimal fits, q*, were compared against the values obtained by the brute force approach for several cases. In all cases, good agreement (discrepancies occurred only in the third significant figure) was achieved. Also, plots for several of the data sets comparing the signal measurements against optimal curve fits were generated and examined to confirm good fits. Several of these are shown in Figure 9 and Figure 10 ((

((I 1]
Comparing ((
)) from theory to experimental measurement is important for application to steam dryer stress evaluation since it allows one to independently check the reliability of the theoretical predictions and also to adjust the theoretical prediction to both better correlate 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. ((

The test data obtained supported the structural model assumptions used in the ANSYS finite element model of the steam dryer. Analysis of these data showed the assumptions are conservative.

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 BWR Steam Dryer Components," Revision 1, prepared by Continuum Dynamics, Inc., dated November 2008. C.D.I. was the developer of the information sought to be withheld and the author of the subject report, and the proprietary information contained therein for the facility on whose docket the information was submitted to the Nuclear Regulatory Commission (NRC).
This Affidavit is submitted to the NRC pursuant lo 10 CFR 2.390(a)(4) based on the fact that the attached information consists of trade secrets, and that the NRC will receive the information under privilege and in confidence. Being responsible for the development of the information and report sought to be withheld, and being knowledgeable of the potential financial impacts of public disclosure of the documents I am in the best position to provide the required information and execute this amended 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 of resources 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 subject information has consistently been held in confidence, no public disclosure has been made and it is not available to the public. All disclosures to third parties, which have been limited, have been made pursuant to the terms and conditions contained in non-disclosure agreements or other legally binding agreements which must be fully executed prior to disclosure.
- 4.
The information is a type customarily held in confidence by C.D.I. and others in the field and 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 of competitive 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 the information'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 BWR steam dryer component is not very well modeled by the conventional practice in the industry of assigning an accepted value to the component.
The Report discloses an analytical methodology, supported by tests and data, that provides a substantially better model of the actual condition of the component. Recognition of the inaccuracy of the accepted practice and knowing the improved value of C.D.I.'s methodology provides a significant competitive advantage over competitors who do not appreciate its significance. This breakthrough was based on the insights and technical creativity of C.D.I. employees and data developed and tests conducted by C.D.I. Based upon C.D.I review of the literature and C.D.I. knowledge of NRC filings by those not having access to the subject report, the information sought to be withheld is not available in public sources.
The information in the document sought to be withheld has provided a significant revenue stream for C.D.I. and has been demonstrated to have significant economic 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 are true and correct to the best of my knowledge, information and belief.
