i INTRODUCTION AND SUMM ARY This report provides the values of the power distribution limits and control rod withdrawal block instrumentation

serpoints for Brunswick Unit 1, Cycle 9 as required by Technical Specification 6.9.3.1. The values of the Average i i Planar Linear Heat Generation Rate (APLHGR) limits, along with associated core flow and core power adjustment l factors are provided as required by Technical Specification 6.9.3.1.a. The values of the Minimum Critical Power l Ratio (MCPR) limits, along with associated core flow and core power adjustment factors are provided as required by Technical Specifications 6.9.3.1.b and 6.9.3.1.c. The control rod block upscale trip setpoints and allowable )

values are provided as required by Technical Specification 6.9.3.1.d.

Per Technical Specification 6.9.3.2 and 6.9.3.3, these values have been determined using NRC-approved methodology and are established such that all applicable limits of the plant safety analysis are met.  ;

Preparation of this repon was performed in accordance with CP&L Nuclear Fuels Management & Safety Analysis Quality Assurance requirements as documented in Reference 1.

APLHGR LIMITS The limiting APLHGR value for the most limiting lattice (excluding natural uranium) of each fuel type as a function of planar average exposure is given in Figures 1 through 6. These values were determined with the SAFER /GESTR LOCA methodology described in GESTAR-II (Reference 2). Figures 1 through 6 are to be used when hand calculations are required as specified in Technical Specification 3.2.1.

The core flow and core power adjustments factors for use in Technical Specification 3.2.1 are presented in Figures 7 and 8. For any given flow / power state the minimum of MAPLHGR(F) determined from Figure 7 and M APLHGR(P) determined from Figure 8 is used to determine the governing limit.

CP&L Nuclear Fuels Mgmt & Safety Analysis File: NF-2202.021 B1C9 Core Operating Limits Report Page 4, Revision 0 MCPR LIMITS i

The ODYN OPTION A, ODYN OPTION B, and non-pressurization transient MCPR limits for use in Technical
Specification 3.2.2.1 and 3.2.2.2 for each fuel type as a function of cycle average exposure are given in Table 1.

These values were determined with the GEMINI methodology and GEXL-PLUS critical power correlation described in GESTAR-ll (Reference 2) and are consistent with the Safety Limit MCPR of 1.07 specified by Technical Specification 2.1.2.

The core flow and core power adjustmenty' factors for use in Technical Specification 3.2.2.1 are presented in Figures  !

9 and 10. For any given flow / power state the maximum of MCPR(F) determined from Figure 9 and MCPR(P) determined from Figure 10 is used to determine the goveming limit.  ;

ROD BLOCK INSTRUMENTATION SETPOINTS The nominal trip setpoints and allowable values of the control rod withdrawal block instrumentation for use in Technical Specification 3.3.4 (Table 3.3.4-2) are presented in Table 2. These values were determined consistent with the bases of the ARTS program and the determination of MCPR limits with the GEMINI methodology and GEXL-PLUS critical power correlation described in GESTAR-II (Reference 2).

l GENERAL ELECTRIC COMPANY AFFIDAVIT l l

1, JAMES F. KLAPPROTil, being duly sworn, depose and state as follows:  !

(1) I am Fuel Licensing Manager, General Electric Company ("GE") 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 document: Loss-of-Coolant Accident Analysis Reportfor Brunswick Steam Electric Plant, Unit 1, Reload 8 Cycle 9, NEDC-31624P, Supplement 1, Revision 1, May 1993. This information is delineated by vertical bars marked in the margin adjacent to the specific material.

(3) In making this application for withholding of proprietary information of which it is the owner, GE 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),2.790(a)(4), a-d 2.790(d)(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, respe.ctively, Critical Mass Enerev Project v. Nuclear l Reculatory Commission. 975F2dS71 (DC Cir.1992), and Public Citizen Health Research l Groua v. FDA, 704F2d1280 (DC Cir.1983).

l l (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 General Electric's competitors without license from General Electric constitutes a competitive economic advantage over other companies; l
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 General Electric, its customers, or its suppliers;

\

d. Information which reveals aspects of past, present, or future General Electric l i

customer-funded development plans and programs, of potential commercial value to General Electric; l l

i l

e. Information which discloses patentable subject matter for which it may be  ;

desirable to obtain patent protection. l (5) The information sought to be withheld is being submitted to NRC in confidence. The information is of a sort customarily held in confidence by GE, 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 GE, 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. Access to such documents within GE is limited on a "need to know" basis.

(7) The procedure for approval of external release of such a docum_ent 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 GE 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 the U-235 enrichment and gadolium distributions for the fuel bundles. In  !

addition, exposure dependent MAPLHGR limits and local peaking factors are provided for each fuel lattice. This information provides insights into the GE thermal / mechanical l criteria, the critical power correlation and the nuclear advantages of the mechanical  ;

improvements incorporated in the fuel design. This information is considered to be i proprietary for the reason set forth in paragraph 4.b, above. l 4

I (9) Public disclosure of the information sought to be withheld is likely to cause substantial  !

harm to GE's competitive position and foreclose or reduce the availability of profit-makin;; upportunities. The information is part of GE's comprehensive BWR technology base, and its ommercial value extends beyond the original development cost.

The value of the technology base goes beyond the extensive physical database and '

l analytical methodology anc includes development of the expertise to detcrmine and apply the appropriate evaluatirn process. In addition, the technology base includes the value i derived from providing analyses done with NRC-approved methods. l A

i l

The research, development, engineering, analytical, and NRC review costs comprise a substantialinvestment of time and money by GE.

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.

The value of this information to GE 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 l competitors with a windfall, and deprive GE of the opportunity to exercise its competitive advantage to seek an adequate return on its large investment in developing these very  ;

valuable analytical tools. r 1
