Florida Power & Light Company, 6501 S. Ocean Drive, Jensen Beach, FL 34957 This letter forwards proprietary information in accordance with 10 CFR 2.390. The balance of this letter may be considered lF= L non-proprietary upon removal of the identified sections of Attachment 5.November 22, 2010 L-2010-259 10 CFR 50.90 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk Washington, DC 20555 Re: St. Lucie Plant Unit I Docket No. 50-335 Renewed License No. DPR-67 License Amendment Request for Extended Power Uprate On April 16, 2010, Florida Power and Light Company (FPL) submitted a license amendment request (LAR) to the U. S. Nuclear Regulatory Commission (NRC) which proposed an amendment to Renewed Operating License No. DPR-67 for St. Lucie Plant Unit I to increase the licensed core power level from 2700 MWt to 3020 MWt. (ML101160182).

By letter dated August 13, 2010, FPL withdrew the April 16, 2010 license amendment request and stated that it may re-submit a revised application at a future time (ML102290018).

The NRC acknowledged FPL's request to withdraw the April 16, 2010 license amendment request by letter dated August 13, 2010 (ML 102240195).

Additionally, the NRC provided supplemental information specifying the areas where additional information was required to enable the NRC staff to complete its detailed review of the application.

Pursuant to 10 CFR 50.90, FPL hereby re-submits a request for an amendment to Renewed Operating License No. DPR-67 for St. Lucie Plant Unit 1. The proposed LAR addresses the information requested in the enclosure to the NRC's letter to FPL dated August 13, 2010 pertaining to Spent Fuel Pool Criticality, Control Rod Withdrawal at Power, and Station Blackout (SBO) Coping Analysis.

Additionally, a summary of the substantive changes made to this LAR is provided in Enclosure I of this letter.an FPL Group company L-2010-259 Page 2 The proposed LAR will increase the licensed core power level of Unit I from 2700 MWt to 3020 MWt and revise the Renewed Operating License and the Technical Specifications to support operation at this increased core thermal power level. This represents a net increase in licensed thermal power of approximately 11.85% and includes a 10.0% extended power uprate and a 1.7% measurement uncertainty recapture (MUR). The net increase from the current core thermal power level is calculated as follows: (2700 MWt x 1.10) x 1.017% z 3020 MWt (3020 -2700 MWt) / 2700 MWt = 11.85%Therefore, this amendment is an Extended Power Uprate (EPU). The increase in core thermal power is currently planned to be accomplished mid-cycle, after the fall 2011 refueling outage.St. Lucie Unit I Amendment No. 48 dated November 23, 1981 (ML013530273)

-approved a Stretch Power Uprate from 2560 MWt to 2700 MWt. The proposed EPU core thermal power level represents an increase of approximatelyl 8 percent from the original licensed thermal power level of 2560 MWt.The proposed LAR was developed using the guidance provided in RS-001, "Review Standard for Extended Power Uprates," Revision 0, dated December 2003 as it applies to the design bases of St. Lucie Plant Unit 1. The proposed LAR was also developed consistent with the format and content contained in the R.E. Ginna Nuclear Power Plant for an EPU (ML051950123).

Plant modifications to support EPU are being implemented over time. A list of key plant modifications (plant changes) associated with the proposed EPU is provided in Attachment 5, Section 1.0.Attachment I contains the Descriptions and Technical Justifications for the changes to the Renewed Facility Operating License, Technical Specifications, and License Basis. In accordance with 10 CFR 50.91 (a)(1), FPL has completed a No Significant Hazards Consideration analysis and concludes that the changes proposed by this license amendment request present no significant hazards under the standards set forth in 10 CFR 50.92(c), and accordingly, a finding of"no significant hazards consideration" is justified.

FPL's No Significant Hazards Consideration analysis is included in Attachment 1.Attachment 2 contains the Supplemental Environmental Report. This report presents FPL's assessment of the environmental impacts associated with St. Lucie Units I and 2 EPU from the current licensed core rated power level of 2700 MWt to an updated core power level of 3020 MWt. This report demonstrates that the EPU will not significantly affect human health or the natural environment.

This attachment is provided to facilitate identification of the proposed changes and retyped Operating License and Technical Specifications pages.Attachment 4 contains the Technical Specification Bases Markups. This attachment is provided as information only to facilitate identification of the proposed bases.Attachment 5 contains the Licensing Report (LR). The LR follows the guidance of RS-001. The LR demonstrates that the EPU can be safely achieved, and that the increase will not be inimical to the common defense and security or to the health and safety of the public. The LR provides the details supporting the requested power uprate, and is supported by the other attachments to the LAR to provide a comprehensive evaluation of the effects of the EPU.

Subject:

Information Supporting St. Lucie Unit I Extended Power Uprate (EPU) (Proprietary)

The proprietary information for which withholding is being requested in the above-referenced report is further identified in Affidavit CAW-1 0-3007 signed by the owner of the proprietary information, Westinghouse Electric Company LLC. The affidavit, which accompanies this letter, sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of 10 CFR Section 2.390 of the Commission's regulations.

Accordingly, this letter authorizes the utilization of the accompanying affidavit by Florida Power & Light Company, in conjunction with its EPU application to the NRC Correspondence with respect to the proprietary aspects of the application for withholding or the Westinghouse affidavit should reference this letter, CAW-1 0-3007, and should be addressed to J. A. Gresham, Manager, Regulatory Compliance and Plant Licensing, Westinghouse Electric Company LLC, P.O. Box 355, Pittsburgh, Pennsylvania 15230-0355.

COUNTY OF HARTFORD: Before ine, the undersigned authority, personally appeared C. M. Molnar, who, being by me duly sworn according to law, deposes and says that lie is authorized to execuite this Affidavit on behalf of Westinghouse Electric Company LLC ("Westinghouse"), and that the averments of fact set forth in this Affidavit are true and correct to the best of his knowledge, information, and belief: C. M. Molnar, Senior Engineer Regulatory Compliance and Plant Licensing Sworn to and subscribed before me this day of Nov ber, 2010., .,'2 ~eme, a Notary ic, in and 'im" County of._Iiartord d CState of 'Connecticut, this day JOA N,_ GRAY Notary Public My Commission Expires January31, 2012 2 CAW-10-3007 (1) I am Senior Engineer, Regulatory Compliance and Plant Licensing, in Nuclear Services, Westinghouse Electric Company LLC (Westinghouse), and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure iII connection with nuclear power plant licensing and rule making proceedings, and am authorized to apply for its withholding on behalf of Westinghouse.

(2) l am making this Affidavit in conformance with the provisions of 10 CFR Section 2.390 of the Commission's regulations and in con Junction with the Westinghouse Application for Withholding Proprietary Information from Public Disclosure accompanying this Affidavit.

(3) 1 have personal knowledge of the criteria and procedures utilized by Westinghouse in designating information as a trade secret, privileged or as confidential commercial or financial information.

(4) Pursuant to the provisions of paragraph (b)(4) of Section 2.390 of tle Commission's regulations, the following is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld.(i) The information sought to be withheld from public disclosure is owned and has been held in confidence by Westinghouse.(ii) The information is of a type customarily held in confidence by Westinghouse and not customarily disclosed to the public. Westinghouse has a rational basis for determining the types of information customarily held in confidence by it and, in that connection, utilizes a system to determine when and whether to hold certain types of information in confidence.

The application of that system and the substance of that system constitutes Westinghouse policy and provides the rational basis required.Under that system, information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitive advantage, as follows: (a) The information reveals tile distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of 3 CAW- 10-3007 Westinghouse's competitors without license from Westinghouse constitutes a competitive economic advantage over other companies.(b) It consists of supporting i data, inciuding test data, relative to a process (or conmponent, structure, tool, method, etc.), the application of which data secures a competitive economic advantage, e.g., by optimization or improved marketability.(c) Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, instal lation assurance of'quality, or licensing a similar product.(d) It reveals cost or price information, production capacities, budget levels, or commercial strategies of Westinghouse, its customers or suppliers.(e) It reveals aspects of past, present, or future Westinghouse or customer funded development plans and programs of potential commercial value to Westinghouse.(f) It contains patentable ideas, for which patent protection may be desirable.

There are sound policy reasons behind the Westinghouse system which inchlde the following: (a) The use of such information by Westinghouse gives Westinghouse a competitive advantage over its competitors.

It is, therefore, withheld from disclosure to protect the Westinghouse competitive position.(b) It is information that is marketable in many ways. The extent to which such information is available to competitors diminishes the Westinghouse ability to sell products and services involving the use of the information.(c) Use by our competitor would put Westinghouse at a competitive disadvantage by reducing his expenditure of resources at our expense.

4 CAW-10-3007 (d) Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive advantage.

If competitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Westinghouse of a competitive advantage.(e) Unrestricted disclosure would jeopardize the position of prominence of Westinghouse in the world market, and thereby give a market advantage to the competition of those countries.(f) The Westinghouse capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.(iii) The information is being transmitted to the Commission in confidence and, under the provisions of 10 CFR Section 2.390; it is to be received in confidence by the Commission.(iv) The information sought to be protected is not available in public sources or available information has not been previously employed in the same original manner or method to the best of our knowledge and belief.(v) The proprietary information sought to be withheld in this submittal is that which is appropriately marked in Florida Power and Light's St. Lucie Unit I extended power uprate (EPU) submittal transmittal letter to the NRC, Attachment 5, Sections:

2.2.2. 1;2.2.2.3, 2.2.2.4; 2.2.2.6; and 2.2.3, transmitted with an Application for Withholding Proprietary Information from Public Disclosure, to the Document Control Desk. The proprietary information as submitted by Westinghouse is that associated with the St.Lucie Unit I EPU license amendment request.This information is part of that which enables Westinghouse to demnonstrate for St. Lucie Unit I structural margins that will exist after the proposed EPU has been implemented.

Further, this information has substantial commercial value, as follows:

5 CAW- 10-3007 (a) Westinghouse generated this inlormation for St. Lucie Unit I, solely For the support of that un it's planned EPU.(b) The information requested to be withheld reveals the stresses and margins for key plant components after thie proposed EPU has been implemented.

Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to provide similar calculations and licensing defense services for commercial power reactors without com mensurate expenses.The development of the technology described in part by the information is the result of applying the results of many years of experience in aii intensive Westinghouse effort and the expenditure of a considerable sum of money.In order for competitors of Westinghouse to duplicate this information, similar technical programs would have to be performed and a significant manpower effort, having the requisite talent and experience, would have to be expended.Further the deponent sayeth not.

PROPRIETARY INFORMATION NOTICE Transmitted herewith are proprietary and/or non-proprietary versions of documents furnished to tile NRC in connection with requests for generic and/or plant-specific review and approval.In order to conform to tile requirements of 10 CFR 2.390 of the Commission's regulations concerning the protection of proprietary information so submitted to the NRC, the information which is proprietary in the proprietary versions is contained within brackets, and whllere the proprietary information has been deleted in the non-proprietary versions, only the brackets remain (the information that was contained within the brackets in the proprietary versions having been deleted).

,: ; ýation of Notaries November 2, 2010 CAW 10-08 1. I am the Director of Sales of Caldon Ultrasonics Technology Center, and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in connection with nuclear power plant licensing and rulemaking proceedings, and am authorized to apply for its withholding on behalf of Cameron.2. I am making this Affidavit in conformance with the provisions of 10 CFR Section 2.390 of the Commission's regulations and in conjunction with the Cameron application for withholding accompanying this Affidavit.

3. I have personal knowledge of the criteria and procedures utilized by Cameron in designating information as a trade secret, privileged or as confidential commercial or financial information.

The material and information provided herewith is so designated by Cameron, in accordance with those criteria and procedures, for the reasons set forth below.4. Pursuant to the provisions of paragraph (b) (4) of Section 2.390 of the Commission's regulations, the following is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld.(i) The information sought to be withheld from public disclosure is owned and has been held in confidence by Cameron.(ii) The information is of a type customarily held in confidence by Cameron and not customarily disclosed to the public. Cameron has a rational basis for determining the types of information customarily held in confidence by it and, in that connection utilizes a system to determine when and whether to hold certain types of information in confidence.

The application of that system and the substance of that system constitutes Cameron policy and provides the rational basis required.

Furthermore, the information is submitted voluntarily and need not rely on the evaluation of any rational basis.

November 2, 2010 CAW 10-08 Under that system, information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential advantage, as follows: (a) The information reveals the distinguishing aspects of a process (or component, structure, tool, method, etc.) where prevention of its use by any of Cameron's competitors without license from Cameron constitutes a competitive economic advantage over other companies.(b) It consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), the application of which data secures a competitive economic advantage, e.g., by optimization or improved marketability.(c) Its use by a competitor would reduce his expenditure of resources or improve his competitive position in the design, manufacture, shipment, installation, and assurance of quality, or licensing a similar product.(d) It reveals cost or price information, production capacities, budget levels, or commercial strategies of Cameron, its customer or suppliers.(e) It reveals aspects of past, present or future Cameron or customer funded development plans and programs of potential customer value to Cameron.(f) It contains patentable ideas, for which patent protection may be desirable.

There are sound policy reasons behind the Cameron system, which include the following: (a) The use of such information by Cameron gives Cameron a competitive advantage over its competitors.

It is, therefore, withheld from disclosure to protect the Cameron competitive position.

November 2, 2010 CAW 10-08 (b) It is information that is marketable in many ways. The extent to which such information is available to competitors diminishes the Cameron ability to sell products or services involving the use of the information.(c) Use by our competitor would put Cameron at a competitive disadvantage by reducing his expenditure of resources at our expense.(d) Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive advantage.

If competitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Cameron of a competitive advantage.(e) Unrestricted disclosure would jeopardize the position of prominence of Cameron in the world market, and thereby give a market advantage to the competition of those countries.(f) The Cameron capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.(iii) The information is being transmitted to the Commission in confidence, and, under the provisions of 10 CFR §§ 2. 390, it is to be received in confidence by the Commission.(iv) The information sought to be protected is not available in public sources or available information has not been previously employed in the same manner or method to the best of our knowledge and belief November 2, 2010 CAW 10-08 (v) The proprietary information sought to be withheld are the submittals titled: " Caldon Ultrasonics Engineering Report ER-740 Rev. 0 "Bounding Uncertainty Analysis for Thermal Power Determination at St. Lucie Unit 1 & 2 Using the LEFMV'+ System"" Caldon Ultrasonics Engineering Report No. ER-733 Rev. 3, "LEFM/+ Meter Factor Calculation and Accuracy Assessment for St. Lucie 1." It is designated therein in accordance with 10 CFR §§ 2.390(b)(1)(i)(A,B), with the reason(s) for confidential treatment noted in the submittal and further described in this affidavit.

This information is voluntarily submitted for use by the NRC Staff in their review of the accuracy assessment of the proposed methodology for LEFM CheckPlus System used by St. Lucie Unit 1 for an MUR UPRATE.Public disclosure of this proprietary information is likely to cause substantial harm to the competitive position of Cameron because it would enhance the ability of competitors to provide similar flow and temperature measurement systems and licensing defense services for commercial power reactors without commensurate expenses.

Also, public disclosure of the information would enable others to use the information to meet NRC requirements for licensing documentation without the right to use the information.

The development of the technology described in part by the information is the result of applying the results of many years of experience in an intensive Cameron effort and the expenditure of a considerable sum of money.In order for competitors of Cameron to duplicate this information, similar products would have to be developed, similar technical programs would have to be performed, and a significant manpower effort, having the requisite talent and experience, would have to be expended for developing analytical methods and receiving NRC approval for those methods.Further the deponent sayeth not.

(2) The information sought to be withheld is Revision 2 of Holtec Report HI-2094486 and Revision 1 of Holtec Report HI-2104714, which contains Holtec Proprietary information and is appropriately marked as such.(3) In making this application for withholding of proprietary information of which it is the owner, Holtec International relies upon the exemption from disclosure set forth in the Freedom of Information Act ("FOIA"), 5 USC Sec. 552(b)(4) and the Trade Secrets Act, 18 USC Sec. 1905, and NRC regulations 1OCFR Part 9.17(a)(4), 2.390(a)(4), and 2.390(b)(1) for "trade secrets and commercial or financial information obtained from a person and privileged or confidential" (Exemption 4). The material for which exemption from disclosure is here sought is all "confidential commercial information", and some portions also qualify under the narrower definition of "trade secret", within the meanings assigned to those terms for purposes of FOIA Exemption 4 in, respectively, Critical Mass Energy Project v. Nuclear Regulatory Commission, 975 F2d 871 (DC Cir.1992), and Public Citizen Health Research Group v. FDA, 704 F2d 1280 (DC Cir. 1983).1 of 5 m Em mE Holtec Center, 555 Lincoln Drive West, Marlton, NJ 08053 H O LT EC Telephone (856) 797-0900 INTERNATIONAL Fax (856) 797-0909 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk AFFIDAVIT PURSUANT TO 10 CFR 2.390 (4) Some examples of categories of information which fit into the definition of proprietary information are: a. Information that discloses a process, method, or apparatus, including supporting data and analyses, where prevention of its use by Holtec's competitors without license from Holtec International constitutes a competitive economic 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 reveals cost or price information, production, capacities, budget levels, or commercial strategies of Holtec International, its customers, or its suppliers;

d. Information which reveals aspects of past, present, or future Holtec International customer-funded development plans and programs of potential commercial value to Holtec International;

e. 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 4.a and 4.b, above.(5) The information sought to be withheld is being submitted to the NRC in confidence.

The information (including that compiled from many sources) is of 2 of 5 EHoitec Center, 555 Lincoln Drive West, Marlton, NJ 08053 H O LT EC Telephone (856) 797-0900 INTERNATIONAL Fax (856) 797-0909 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk AFFIDAVIT PURSUANT TO 10 CFR 2.390 a sort customarily held in confidence by Holtec International, and is in fact so held. The information sought to be withheld has, to the best of my knowledge and belief, consistently been held in confidence by Holtec International.

No public disclosure has been made, and it is not available in public sources. All disclosures to third parties, including any required transmittals to the NRC, have been made, or must be made, pursuant to regulatory provisions or proprietary agreements which provide for maintenance of the information in confidence.

Its initial designation as proprietary information, and the subsequent steps taken to prevent its unauthorized disclosure, are as set forth in paragraphs (6) and (7)following.

(6) Initial approval of proprietary treatment of a document is made by the manager of the originating component, the person most likely to be acquainted with the value and sensitivity of the information in relation to industry knowledge.

Access to such documents within Holtec International is limited on a "need to know" basis.(7) The procedure for approval of external release of such a. document typically requires review by the staff manager, project manager, principal scientist or other equivalent authority, by the manager of the cognizant marketing function (or his designee), and by the Legal Operation, for technical content, competitive effect, and determination of the accuracy of the proprietary designation.

Disclosures outside Holtec International are limited to regulatory bodies, customers, and potential customers, and their agents, suppliers, and licensees, and others with a legitimate need for the information, and then only in accordance with appropriate regulatory provisions or proprietary agreements.

(8) The information classified as proprietary was developed and compiled by Holtec International at a significant cost to Holtec International.

This information is classified as proprietary because it contains detailed descriptions of analytical 3 of 5 M M M mI Holtec Center, 555 Lincoln Drive West, Marlton, NJ 08053 H O LT EC Telephone (856) 797-0900 INTERNATIONAL Fax (856) 797-0909 U.S. Nuclear Regulatory Commission ATTN: Document Control Desk AFFIDAVIT PURSUANT TO 10 CFR 2.390 approaches and methodologies not available elsewhere.

This information would provide other parties, including competitors, with information from Holtec International's technical database and the results of evaluations performed by Holtec International.

A substantial effort has been expended by Holtec International to develop this information.

Release of this information would improve a competitor's position because it would enable Holtec's competitor to copy our technology and offer it for sale in competition with our company, causing us financial injury.(9) Public disclosure of the information sought to be withheld is likely to cause substantial harm to Holtec International's competitive position and foreclose or reduce the availability of profit-making opportunities.

The information is part of Holtec International's comprehensive spent fuel storage technology base, and its commercial value extends beyond the original development cost. The value of the technology base goes beyond the extensive physical database and analytical methodology, and includes development of the expertise to determine and apply the appropriate evaluation process.The research, development, engineering, and analytical costs comprise a substantial investment of time and money by Holtec International.

The precise value of the expertise to devise an evaluation process and apply the correct analytical methodology is difficult to quantify, but it clearly is substantial.

Holtec International's competitive advantage will be lost if its competitors are able to use the results of the Holtec International experience to normalize or verify their own process or if they are able to claim an equivalent understanding by demonstrating that they can arrive at the same or similar conclusions.

Making such information available to competitors without their having been required to undertake a similar expenditure of resources would unfairly provide competitors with a windfall, and deprive Holtec International of the opportunity to exercise its competitive advantage to seek an adequate return on its large investment in developing these very valuable analytical tools.Executed at Marlton, New Jersey, this 5 th day of November, 2010)~- Jay Leff Project Manager Holtec InternationalMASS't40XS PBUIC bNE4W jEsSEY WOTAVEYpUBUs~pd

Subject:

Section 2.2.2.5 of Florida Power and Light's St. Lucie Unit 1 EPU submittal transmittal letter to the NRC, Attachment 5 (Proprietary)

Dear Sir/Madam:

The proprietary information for which withholding is being requested in the above-referenced document section is identified in the attached affidavit signed by the owner of the proprietary information, Babcock &Wilcox Canada Ltd. The affidavit, which accompanies this letter, sets forth the basis on which the information may be withheld from public disclosure by the Commission and address with specificity the considerations listed in paragraph (b)(4) of 10 CFR Section 2.390 of the Commission's regulations.

Accordingly, this letter authorizes the utilization of the accompanying affidavit by Florida Power and Light.Correspondence with respect to the proprietary aspects of the application for withholding or the Babcock &Wilcox Affidavit should reference this letter, and should be addressed to the undersigned.

Yours truly, BABCOCK & WILCOX CANADA LTD.yMillman, Manager, Nuclear Engineering Attach./Cc: V.J. Manica J. MacQuarrie J. Albert PROVINCE OF ONTARIO REGIONAL MUNICIPALITY OF WATERLOO AFFIDAVIT OF JEFFREY MILLMAN I, Jeffrey Millman, of the Village of Ayr, in the Township of North Dumfries, Regional Municipality of Waterloo, in the Province of Ontario, being sworn, make oath and say as follows: 1. I am the Manager, Nuclear Engineering of Babcock & Wilcox Canada Ltd. ("B&W"), and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in connection with nuclear power plant licensing and rulemaking proceedings, and am authorized to apply for its withholding on behalf of B&W.2. I am making this Affidavit in conformance with the provisions of 10CFR Section 2.390 of the Commission's regulations and in conjunction with the Babcock & Wilcox Canada Ltd. Application for Withholding accompanying this Affidavit.

3. I have personal knowledge of the criteria and procedures utilized by B&W in designating information as a trade secret, proprietary or as confidential commercial or financial information.

4. Pursuant to the provisions of paragraph (b)(4) of Section 2.390 of the Commission's regulations, the following is furnished for consideration by the Commission in determining whether the information sought to be withheld from public disclosure should be withheld.(i) The information sought to be withheld from public disclosure is owned and has been held in confidence by B&W.(ii) The information is of a type customarily held in confidence by B&W and not customarily disclosed to the public. B&W has a rational basis for determining the types of information customarily held in confidence by it and, in that connection, utilizes a system to determine when and whether to hold certain types of information in confidence.

The application of that system and the substance of that system constitutes B&W policy and provides the rational basis required.Under that system, information is held in confidence if it falls in one or more of several types, the release of which might result in the loss of an existing or potential competitive advantage, as follow: (a) The information reveals the distinguishing aspects of a process, component, structure, tool, method, etc., where prevention of its use by 2 any of B&W's competitors without license from B&W constitutes a competitive economic advantage over other companies.(b) It consists of supporting data, including test data, relative to a process (or component, structure, tool, method, etc.), the application of which data secures a competitive economic advantage, e.g., by optimization or improved marketability.(c) Its use by a competitor would reduce its expenditure of resources or improve its competitive position in the design, manufacture, shipment, installation, quality assurance, or licensing of a similar product.(d) It contains patentable ideas, for which patent protection may be desirable.

There are sound policy reasons behind the B&W system which include the following:

• The use of such information by B&W gives B&W a competitive advantage over its competitors.

It is, therefore, withheld from disclosure to protect B&W's competitive advantage.

• It is information which is marketable in many ways. The extent to which such information is available to competitors diminishes the B&W ability to sell products and services involving the use of such information." Use by a competitor of B&W would put B&W at a competitive disadvantage by reducing the competitor's expenditure of resources at B&W's expense.* B&W's capacity to invest corporate assets in research and development depends upon the success in obtaining and maintaining a competitive advantage.(iii) The information is being transmitted to the Commission in confidence and, under the provisions of 1OCFR Section 2.390, it is to be received in confidence by the Commission.(iv) The information sought to be protected is not available in public sources or available information has not been previously employed in the same original manner or method to the best of our knowledge and belief.(v) The proprietary information sought to be withheld in this submittal is that which is identified in Florida Power and Light's St. Lucie Unit 1 EPU submittal transmittal letter to the NRC, Attachment 5, Section 2.2.2.5 and Application for Withholding Proprietary Information from Public Disclosure, to the Document Control Desk.

3 The information which is proprietary in the proprietary version is contained within brackets, and where the proprietary information has been deleted in the non-proprietary versions, only the brackets remain (the information that was contained within the brackets in the proprietary versions having been deleted).The justification for claiming the information so designated as proprietary is indicated in both versions by means of lower case letters (a) through (d) located as a superscript immediately following the brackets enclosing each item of information being identified as proprietary.

These lower case letters refer to the types of information B&W customarily holds in confidence identified in Sections (4)(ii)(a) through (4 )(ii)(d) of this affidavit pursuant to 10 CFR 2.390(b)(1).
