: 10. Local Rod Withdrawal Error (With Limiting Instrument Failure) AOO Summary The rod withdrawal error (RWE) event in the maximum extended operating domain was originally analyzed in the GE BWR Licensing Report, Maximum Extended Operating Domain Analysis for Brmnsw!ck Steam Electric Plant, NEDC-31654P, February 1989. The MCPRs for Brunswick Unit I Cycle 16 RWE are not generally bounded by the safety limit adjusted operating limit MCIPRs in Table 10-5(a) or 10-5(b) of NEDC-31654P. The limiting results are shown in the table below for the RBM System setpoints shown in Table 10-5(c) of NEDC-31654P. The RBM operability requirements specified in Section 10.5 of NEDC-31654P (for RBM inoperable: OLMCPR 2 1.40 for power 2 90% and OLMC1'R 2 1.70 for power < 90%) have been evaluated and shown to be sufficient to ensure that the Safety Limit MCPR will not be exceeded in the event of an unblocked RWE event. In addition, the cladding 1%plastic strain criteria have been met.

: 15. Stability Analysis Results 15.1 Introduction The BVWROG Regional Mode DIVOM Guideline recommends that a plant specific DIVOM slope be used for Option III OPRM setpoint determination (Reference 1 in Section 15.4).
However, since Brunswick Unit I will be implementing the Detect and Suppress Solution - Confirmation Density (DSS-CD) solution in the near future, the interim DIVOM approach as a function of Figure of Merit Mill be applied until DSS-CD is implemented (Reference 2 in Section 15.4).
Should the Option III OPRM system be declared inoperable, the BWROG Interim Corrective Action will constitute the stability licensing basis for Brunswick Unit I Cycle 16.
15.2 Stability Option III Brunswick Unit I has implemented BWROG Long Term Stability Solution Option III (Oscillation Power Range lvlonitor-OPRM) as described in Reference 3 in Section 15.4. Plant specific analysis incorporating the Opi:ion III hardware is described in Reference 4 in Section 15.4.

The stability based MCPR Operating Limit is provided for two conditions as a function of OPRM amplitude setpoint in the following table. The two conditions evaluated are for a postulated oscillation at 45% rated core flow steady state operation (SS) and following a two recirculation pump trip (2PT) from the limiting full power operation state point. Current power and flow dependent limits provide adequate protection against violation of the Safety Limit MCPR for postulated reactor instability as long as the operating limit is greater than or equal to the specified value for the selected OPRM setpoint.
The stability-based OLMCPR was calculated for Cycle 16. The reload validation calculation demonstrated that reactor stability does not produce the limiting OLMCPR for Cycle 16 as long as the selected OPRM setpoint produces values for OLMCPR(SS) and OLMCPR(2PT) that are less than the corresponding acceptance criteria.

16.3 ECCS-LOCA Operating Limits The ECCS MAPLHGR operating limits have been merged with the thermal-hydraulic MAPLBGR operating limits to produce a set of fuel type dependant composite MAPLHGR limits representing the most restrictive values of both. The most and least limiting values of these composite MAPLHGRs for each of the new fuel bundles in this cycle are shown in the tables below. The MAPLHGR operating limits for the remaining fuel bundles are documented in References 2 and 3 for GE14C in Section 16.4.

The use of this code is permitted in GESTAR II. The transient plots, neutron flux and he.t flux values normally reported in Section 9 are not an output of the BWR Simulator Code; therefore, those items are not included in this document. The OLMCPR result is shown in Section 11.
In addition, the Inadvertent HPCI start-up event was shown to be bounded by the LFWH event in Brunswick Unit I Cycle 16 in accordance with Reference B-i.

For MSIVOOS, the OLMCPRs presented in Section 11 and peak overpressure results in Section 12 are bounding. MSIVOOS will not be allowed while operating in the MELLLA+ domain (See Appendix E).
Reference C-2 provides a basis for operation of the Brunswick Steam Electric Plant (BSEP) with Feedwater Temperature Reduction (FWTR). The required OLMCPRs are provided in Section 11. FWITR and FWHOOS will not be allowed while operating in the MELLLA+ domain (See Appendix E).
Reference C-3 provides a basis for operation of the Brunswick Steam Electric Plant (BSEP) with Maximum Extended Operating Domain (MEOD). The required OLMCPRs are provided in Section 1]..
Reference C4 provides a basis for operation of the Brunswick Steam Electric Plant (BSEP) with all Turbine Bypass Valves Out of Service (TBVOOS). The required OLMCPRs are provided in Section Il .
The impact of GE14 fuel on the operating flexibility options is addressed in Reference C-5.
The ARTS power and flow dependent operating limits for all operating flexibility options are provided in References C-9, C-3, and C-6. The ARTS power and flow dependent MCPR limits apply to two recirculation pump system operation and SLO without modification for Brunswick Unit I Cycle 16.
The ARTS power dependent limits in Reference C-9 include an adjustment to the limits provided in References C-3 and C-5 to address the 10 CFR Part 21 Communication in Reference C-8. The pcwer dependent MCPR limits in Reference C-9 also include an adjustment to the K(p) above P-bypass due to the implementation of TRACG (Reference C-7). The MCPR(p) limits provided in Reference C-9 are based on a Safety Limit of 1.11. The Reference C-9 power dependent limits are not altered for Brunswick Unit I Cycle 16.
The ARTS flow dependent limits provided in Reference C-3 are based on a Safety Limit of 1.07. Du.e to the safety limit change for Brunswick Unit I Cycle 16, there will be a required adjustment to the MCPR(f) limits and a validation of the required minimum GE14 OLMCPR for the recirculation pump seizure event. The Reference C-3 MCPR(f) limits are increased for a Safety Limit of 1.11 by the ratio of (1.11/1.07). The following coefficients apply:

From Reference C-5, the SLO OLMCPR was determined to be 1.40 with a SLO SLMCPR of 1.12. The initial rower for the licensing basis pump seizure event is 2143 MWth, which was about 83.8% of the plant licensed thermal power at the time of the analysis. Consequently, the K(P) for this power level from Reference C-5 was approximately 1.06, resulting in a minimum TLO OLMCPR of 1.32 to cover the pump srizure event for GE14 fuel for a SLO SLMCPR of 1.12. After EPU, the licensing basis GE14 pump seizure initial power in MW~h is unchanged, but represents about 73.3% of licensed thermal power, resulting in a K(P) of about 1.12. Since the SLO SLMCPR is 1.12 for Brunswick Unit 1 Cycle 16, the SLO OLMCPR must be greater than or equal to 1.40 for the pump seizure event. Therefore, the minimum GE14 OLMCPR of 1.34 (See Section 11) is conservative for the SLO pump seizure event (1.34*K(73.3) = ].34* 1.12= 1.50> 1.40).

BRUNSWICK UNIT I                                                                  0000-0038-9350-SRILR Reload 15                                                                                      Reviqion 0 Appendix E MELLLA+ Implementation Brunswick is seeking approval to operate in the MELLLA+ domain (Reference E-1), which would provide greater core flow flexibility, particularly as power approaches 120% of the original licensed thermal power (OLTP). Approval is not expected prior to startup of Brunswick Unit I Cycle 16.
However, the cycle-specific reload licensing analyses were performed to support operation with or without the MELLLA+ domain. Special consideration of MELLLA+ was given during performancL- of the trans;ient analyses, stability analyses, and LOCA analyses.
The pressurization transients are generally limiting at high flow conditions. However, the transients vwere performed at both the minimum MELLLA+ flow (85%) and the maximum ICF flow (104.5%). This ensures that the pressurization transient results bound both MELLLA and MELLLA+. Additionally, the loss of feedwater heating (LFWH) transient, which is more limiting at low flow, was performed at the minimum MELLLA+ flow. Therefore, the limiting subcooling transient bounds both MELLLA and MELLLA+. Reduced feedwater temperature (FFWTR and FWHOOS) and single loop operation (SLO) will not be allowed in conjunction with operation in the MELLLA+ domain. Further, no SRVs will be allowed to be out of service in the MELLLA+ domain. However, the pressurization transients were performed at MELLLA+ with I SRV out of service to ensure that both MELLLA and MELLLA+ are bounded. Finally, TBVOOS will be allowed in the MELLLA+ domain, but MSIVOOS will not.
For EPUJ/MELLLA+ operation, the Detect and Suppress Solution - Confirmation Density (DSS-CD) is the licensing basis for Brunswick Unit I Cycle 16. The reload checklist as outlined in Reference E-2 and shown .n Table E-l is used to confirm that the DSS-CD is applicable to Brunswick Unit I Cycle 16 EPU/M ELLLA+ operation.

Specifically, the NFWT and RFWT limits are separated at any cycle exposure for which the TBPOOS operating flexibility option is employed. The RFWT limits apply to both feedwater temperature reduction and feedwater heater out of service. The results of the analyses are insensitive to feedwater temperature deviations of less than 10"F.

BSEP 06-0034 Enclosure 4 Global Nuclear Fuels Affidavit Regarding Withholding NEDC-31624P, Supplement 1, Revision 9, From Public Disclosure

Affidavit Affidavit I, Andrew A. Lingenfelter, state as follows:
(1) I am Manager, Fuel Engineering Services, Global Nuclear Fuel - Americas, L.L.C. ("GNF-A") and 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 the attachment, "NEDC-31624P, Supplement 1, Revision 9, Loss-of-Coolant Accident Analysis Report for Brunswick Steam Electric Plant Unit I Reload 15 Cycle 16," December 2005.
GNF proprietary information is indicated by enclosing it in double brackets. In each case, the superscript notation 13) 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, GNF-A 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 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 Proiect v. Nuclear Regulatorv 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 GNF-A's competitors without license from GNF-A 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 GNF-A, its customers, or its suppliers;
: d. Information which reveals aspects of past, present, or future GNF-A customer-funded development plans and programs, of potential commercial value to GNF-A;
: e. Information which discloses patentable subject matter for which it may be desirable to obtain patent protection.

Affidavit 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 the 10 CFR 2.390 (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 GNF-A, and is in fact so held. Its initial designation as proprietary information, and the subsequent steps taken to prevent its unauthorized disclosure, are as set forth in (6) and (7) following. The information sought to be withheld has, to the best of my knowledge and belief, consistently been held in confidence by GNF-A, 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.
(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 GNF-A. Access to such documents within GNF-A 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 delegate), and by the Legal Operation, for technical content, competitive effect, and determination of the accuracy of the proprietary designation. Disclosures outside GNF-A 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) is classified as proprietary because it contains details of GNF-A's fuel design and licensing methodology.
The development of the methods used in these analyses, along with the testing, development and approval of the supporting methodology was achieved at a significant cost, on the order of several million dollars, to GNF-A or its licensor.
(9) Public disclosure of the information sought to be withheld is likely to cause substantial harm to GNF-A's competitive position and foreclose or reduce the availability of profit-making opportunities. The fuel design and licensing methodology is part of GNF-A'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 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 GNF-A or its licensor.

A ffiavit 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.
GNF-A's competitive advantage will be lost if its competitors are able to use the results of the GNF-A 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 GNF-A 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 GNF-A 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 at Wilmington, North Carolina, this       /1       day of      December,    2005.
