SUMMARY

This report documents the development of the steam dryer instrumentation acceptance criteria and provides the acceptance limit curves that will be used to confirm the acceptability of the Susquehanna Steam Electric Plant (SSES) replacement steam dryer to withstand the effects of flow induced vibration at Extended Power Uprate (EPU) conditions. Acceptance criteria are developed for the on-dryer installed instrumentation. The acceptance criteria presented in this report will be incorporated into the Power Ascension Test Plan (PATP) for the replacement stream dryer.1 GE-NE-0000-0080-2994-NP-R2 NON-PROPRIETARY VERSION 2. INTRODUCTION AND BACKGROUND The first replacement steam dryer installed in SSES will be instrumented [[]] The locations for the dryer instrumentation sensors are shown in Figures 1"1 through 1-4.[[11 During the steady state conditions after the first two power ascension -steps -103.5% and-107% of 3489 MWT, the dryer data will be compared to the acceptance limits. If a measurement exceeds the Level 1 criteria, a reduction in power to the previously acceptable power level is required. The level 2 criteria are used to provide margin to the Level 1 criteria. If a 2 GE-NE-OOOO-0080-2994-N P-R2 NON-PROPRIETARY VERSION measurement exceeds the Level 2 criteria, the plant shall hold at the current power level and re-evaluate the dryer loading and structural response.The rate of increase dryer gages shall be monitored to identify whether there are resonance frequencies increasing above nominal levels in proportion to instrumentation data.Acceptance criteria for the on-dryer mounted instrumentation was previously developed in Reference 1 based upon the Reference 2 finite element (FE) model stress results. This was provided to the NRC as an Attachment to Reference

1. As part of the Susquehanna license for Extended Power Uprate, it was required that PPL provide dryer sensor acceptance criteria based on the final as-designed dryer. This report provides the dryer gage acceptance criteria as required by the NRC.The acceptance criteria developed in this report are based on the as designed and fabricated SSES replacement steam dryer FE model results documented in Reference
3. The acoustic loads used in the stress analysis were developed in Reference 4 and were not affected by the structural differences in the dryer design represented by the two FE models. The existing Susquehanna steam dryer was instrumented previously in 1985 as documented in Reference 5.3 G E-N E-OOOO-0080-2994-N P-R2 NON-PROPRIETARY VERSION U.4-.4.+.4.4 11 Table 1-1 Replacement Dryer [[1] Sensor Locations 4 GE-N E-OOOO-0080-2994-N P-R2 NON-PROPRIETARY VERSION S G E-N E-OOOO-0080-2994-N P-R2 NON-PROPRIETARY VERSION 6 GE-NE-OOOO-0080-2994-N P-R2 NON-PROPRIETARY VERSION 7 GE-N E-OOOO-0080-2994-N P-R2 NON-PROPRIETARY VERSION 3.

Abney, state as follows: (1) I am Vice President, Services Licensing, Regulatory Affairs, GE-Hitachi Nuclear Energy Americas LLC ("GEH"), have been delegated the function of reviewing the information described in paragraph (2) which is sought to be withheld, and have been authorized to apply for its withholding. (2) The information sought to be withheld is contained in GEH proprietary report, GE-NE-0000-0080-2994-P-R2, Susquehanna Replacement Steam Dryer Instrumentation Acceptance Criteria -Dryer Mounted Instrumentation, February, 2008. The proprietary information is identified by a dotted underline inside double square brackets. [[..h.i.h. sentence is an ex.a.m.pe.. 3.)]] In each case, the superscript notation {3} refers to Paragraph (3)of this affidavit, which provides the basis for the proprietary determination. (3) In making this application for withholding of proprietary information of which it is the owner or licensee, GEH 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 10 CFR 9.17(a)(4), and 2.390(a)(4) for "trade secrets" (Exemption 4). The material for which exemption from disclosure is here sought 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, 975F2d871 (DC Cir. 1992), and Public Citizen Health Research Group v. FDA, 704F2d1280 (DC Cir. 1983).(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 GEH's competitors without license from GEH 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 aspects of past, present, or future GEH customer-funded development plans and programs, resulting in potential products to GEH;d. Information which discloses patentable subject matter for which it may be desirable to obtain patent protection.

Aff GE-NE-0000-0080-2994-P-R2 Affidavit Page I of 3 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) To address 10 CFR 2.3 90(b)(4), the information sought to be withheld is being submitted to NRC in confidence. The information is of a sort customarily held in confidence by GEH, 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 GEH, no public disclosure has been made, and it is not available in public sources. All disclosures to third parties, including any required transmittals to 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, or subject to the terms under which it was licensed to GEH. Access to such documents within GEH 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 for technical content, competitive effect, and determination of the accuracy of the proprietary designation. Disclosures outside GEH 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 identified in paragraph (2) above is classified as proprietary because it contains results and details of structural analysis methods and techniques developed by GEH for evaluations of BWR Steam Dryers. Development of these methods, techniques, and information and their application to the design, modification, and analyses methodologies and processes for the Steam Dryer Program was achieved at a significant cost to GEH.The development of the evaluation process along with the interpretation and application of the analytical results is derived from the extensive experience database that constitutes a major GEH asset.(9) Public disclosure of the information sought to be withheld is likely to cause substantial harm to GEH's competitive position and foreclose or reduce the availability of profit-making opportunities. The information is part of GEH's comprehensive BWR safety and 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 Aff GE-NE-0000-0080-2994-P-R2 Affidavit Page 2 of 3 the appropriate evaluation process. In addition, the technology base includes the value derived from providing analyses done with NRC-approved methods.The research, development, engineering, analytical and NRC review costs comprise a substantial investment of time and money by GEH.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. GEH's competitive advantage will be lost if its competitors are able to use the results of the GEH 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. The value of this information to GEH would be lost if the information were disclosed to the public. 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 GEH of the opportunity to exercise its competitive advantage to seek an adequate return on its large investment in developing and obtaining these very valuable analytical tools.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.Executed on this 21st day of February 2008.Tim E. Abney GE-Hitachi Nuclear Energy Americas LLC Aff GE-NE-0000-0080-2994-P-R2 Affidavit Page 3 of 3}}
