Bilanin, being duly sworn, depose and state as follows: 1 .I hold the position of President and Senior Associate of Continuum Dynamics, Inc. (hereinafter referred to as C.D.I.), and I am authorized to make the request for withholding from Public Record the Information contained in the documents described in Paragraph
- 2. This Affidavit is submitted to the Nuclear Regulatory Commission (NRC) pursuant to 10 CFR 2.390(a)(4) based on the fact that the attached information consists of trade secret(s) of C.D.I. and that the NRC will receive the information from C.D.I. under privilege and in confidence.
- 2. The Information sought to be withheld, as transmitted to PSEG Nuclear LLC as attachment to C.D.I. Letter No. 08020 dated 30 January 2008, Revised Response to RAI 14.66 2 nd Follow-Up.
- 3. The Information summarizes: (a) a process or method, including supporting data and analysis, where prevention of its use by C.D.I.'s competitors without license from C.D.I. constitutes a competitive advantage over other companies;(b) Information which, if used by a competitor, would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing of a similar product;(c) Information which discloses patentable subject matter for which it may be desirable to obtain patent protection.
The information sought to be withheld is considered to be proprietary for the reasons set forth in paragraphs 3(a), 3(b) and 3(c) above.4. The Information has been held in confidence by C.D.I., its owner. The Information has consistently been held in confidence by C.D.I. and no public disclosure has been made and it is not available to the public. All disclosures to third partiks, which have been limited, have been made pursuant to the terms and conditions contained in C.D.I.'s Nondisclosure Secrecy Agreement which must be fully executed prior to disclosure.
- 5. The Information is a type customarily held in confidence by C.D.I. and there is a rational basis therefore.
The Information is a type, which C.D.I. considers trade secret and is held in confidence by C.D.I. 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 C.D.I.'s competitive position and foreclose or reduce the availability of profit-making opportunities. I declare under penalty of perjury that the foregoing affidavit and the matters stated therein are true and correct to be the best of my knowledge, information and belief.Executed on this day of -. 1 2008.Alan J. Bilanin Continuum Dynamics, Inc.Subscribed and sworn before me this day:~ reiste '~ayPublic EILEEN P. BURMEISTER NOTARY PUBLIC OF NEW JERSEY MY COMM. EXPIRES MAY 6, 2012 LR-N08-0033 C.D.I. Proprietary Information ATTACHMENT 2 Hope Creek Generating Station Facility Operating License NPF-57 Docket No. 50-354 Extended Power Uprate Response to Request for Additional Information In Reference 1, PSEG Nuclear LLC (PSEG) requested an amendment to Facility Operating License NPF-57 and the Technical Specifications (TS) for the Hope Creek Generating Station (HCGS) to increase the maximum authorized power level to 3840 megawatts thermal (MWt).In Reference 2, the NRC requested additional information concerning PSEG's request.PSEG provided responses to two of the NRC questions in Reference
- 3. PSEG's response to the remaining NRC question is provided below. Additional information on the differences between measured and inferred finite element model damping values, as discussed in Reference 3, is also provided below.RAI 14.66 2nd Follow-Up -I Page 22 of Continuum Dynamics, Inc. (CDI) Report 07-27P, "Finite Element Modeling Bias and Uncertainty Estimates Derived from the Hope Creek Unit 2 Dryer Shaker Test, Rev. 0," presents damping values computed for the finite element (FE) model to best match FE and measured acceleration response function peaks. CDI states that the inferred FE damping values are consistent with measured damping values in STI Technologies Report PA2168, "Hope Creek Steam Dryer Vibration Test." However, no damping values (other than those for low frequency rigid body modes) are presented in the STI report.(c) Reconcile the differences between the measured and inferred FE damping values, and provide the resulting FE bias and uncertainty.
Revised Response[[ LR-N08-0033 C.D.I. Proprietary Information Attachment 2 Page 2 The resulting FE bias and uncertainty is included in the stress margin reported in C.D.I. report 07-17P, Rev. 4 (Attachment 3 to this, letter).Reference 14.66-1 Letter from STI Technologies to S. Kugler (PSEG Nuclear LLC), January 28, 2008 RAI 14.120(e) -2 nd Follow-up PSEG states that the final dryer stress margin is provided in CDI report 07-17P, Rev. 3.The final dryer alternating stress margin with all bias errors and uncertainties included is 3.22 at CLTP. Since PSEG is currently responding to the two staff RAI items on CDI Report 07-27P, "Finite Element Modeling Bias and Uncertainty Estimates Derived from the Hope Creek Unit 2 Dryer Shaker Test, Rev. 0", and will soon respond to RAI 14.79 -3 rd follow-up, it should update CDI Report 07-17P, Rev. 3, with the final bias and uncertainties along with the final stress margin. The revised report should also include a summary table of the final values of the bias errors and uncertainties along with references to the derivations. Response C.D.I. Report 07-17P, Rev. 4, is provided in Attachment 3 to this letter. Biases and uncertainties are included with references in Tables 11 and 12 in the C.D.I. Report.References
