Table 3.3.1.1-1 Revise Reactor Vessel Steam Dome Pressure - High scram trip allowable value consistent with the discussion in Section 5.3.1 and analytical limit in Table 5-1 SR3.3.4.2.4 Consistent with the nominal operating reactor dome pressure increase shown in Table 1-2 and the discussion in Section 5.3.2, increase the ATWS recirculation pump trip pressure allowable value (from 1135 psig to 1165 psig), based on the analytical limit in Table 5-1.

SR3.3.6.4.3a, b Consistent with the increased nominal reactor dome pressure shown in SR3.4.4.1 Table 1-2 and the discussion in Section 5.3.3, increase the SRV relief, B3.4.4 LLS function and spring safety lift settings as shown in Table 5-1.

B3.6.1.6 SR3.5.3.3 As discussed in Section 3.8, to be consistent with the nominal reactor dome pressure change, increase the RCIC Surveillance test high pressure value by the same amount as the nominal reactor dome pressure increase shown in Table 1-2 (from 1045 psig to 1075 psig).

Table 3.3.6.1-1 Consistent with the increased rated steam flow shown in Table 1-2 and the discussion in Section 5.3.4, revise the Main Steam Line Flow - High pressure isolation trips, based on the analytical limits shown in Table 5-1.

3.4 As discussed in Section 3.4, based on the ratio of the current rated to 3.4.1 B uprated % power values (100/105), decrease the thermal power value by 100/105 for single loop operation (SLO), to maintain the same SLO absolute thermal power range (83% to 79%).

SR3.4.6.1 For isolation valve leakage, increase the base reactor coolant system pressure by the same amount as the nominal reactor dome pressure increase shown in Table 1-2 (from 1010 psig to 1040 psig, and from 1040 psig to 1070 psig).

Figure 3.4.11-1 Replace the Minimum Reactor Pressure Vessel Metal Temperature vs.

SR3.4.11-1 Reactor Vessel Pressure curves, as discussed in Section 3.3.1.1, with B3.4.11 those shown in Figures 3-2a and 3-2b.

Reactor Core SLs B 2.1.1 BASES APPLICABLE 2.1.1.1 Fuel Claddino Inteority (continued) '

SAFETY ANALYSES indicate that the fuel assembly critical power at this flow is approximately 3.35 MWt. With the design peaking factors, this corresponds to a THERMAL POWER > 50% TP. Thus, a THERMAL POWER limit of RTP for eactor pressure < 785 psig is conservat v .

l 0

2.1.1.2 MCPR The fuel cladding integrity SL is set such that no significant fuel damage is calculated to occur if the limit is not violated. Since the parameters that result in fuel damage are not directly observable during reactor operation, the thermal and hydraulic conditions that result in the onset of transition boiling have been used to mark the beginning of the region in which fuel damage could occur.

Although it is recognized that the onset of transition boiling would not result in damage to BWR fuel rods, the critical power at which boiling transition is calculated to occur has been adopted as a convenient limit. However, the uncertainties in monitoring the core operating state and in the procedures used to calculate the critical power result in an uncertainty in the value of the critical power.

Therefore, the fuel cladding integrity SL is defined as the critical power ratio in the limiting fuel assembly for which more than 99.9% of the fuel rods in the core are expected to avoid boiling transition, considering the power distribution l

within the core and all uncertainties.

The MCPR SL is determined using a statistical model that combines all the uncertainties in operating parameters and the procedures used to calculate critical power. The probability of the occurrence of boiline transition is determined using the approved General Electric critical power correlations. Details of the fuel cladding integrity SL calculation are given in Reference 2. Reference 2 also includes a tabulation of the uncertainties used 1n the determination of the MCPR SL and of the nominal values of the parameters used in the MCPR SL statistical analysis.

In this event, the associated control red is declared inoperable (Required Action A.2) and LCO 3.1.3 entered.

8.1. B.2.1. and 8.2.2 With two or more control rod scram accumulators inoperable and reactor steam done pressure a 600 psig, adequate i pressure must be supplied to the charging water header.

With inadequate charging water pressure, all of the accumulators could become inoperable, resulting in a potentially severe degradation of the scram performance.

Therefore, within 20 sing a from discovery of charging water header pressure < & 4Bpsig concurrent with O, condition B, acequate charging water header pressure must be l restored. The allowed Completion Time of 20 minutes is considered a reasonable time to place a CRD pump into service to restore the charfling header pressure, if required. This Completion 'ine also recognizes the ability of the reactor pressure alone to fully insert all control rods.

The control rod may be declared " slow." since the control rod will still scram using only reactor pressure, but may not satisfy the times in Table 3.1.4 1. Required Action B.2.1 is modified by a Note indicating that declaring the control rod " slow" is only applicable if the associated control scram time was within the Otherwise, limits of Table 3.1.4-1rod the control during the last scram time test.

(continued)

The reactor mode switch must be immediately placed in the shutdown position if either Required Action and associated Completion Time associated with the loss of the CRD pump (Required Actions B.1 and C.1) cannot be met. This ensures l that all insertable control rods are inserted and that the reactor is in a condition that does not require the active function (i.e., scram) of the control. rods. This ReQutred Action is modified by a Note stating that the Required Action is not applicable if all control rods associated with the inoperable scram accumulators are fully inserted, since the function of the control rods has been performed.

SURVEILLANCE SR 3.1.5.1 REQUIREMENTS SR 3.1.5.1 requires that the accumulator pressure be checked every 7 days to ensure adequate accumulator pressure exists to provide sufficient scram force. The primary indicator of accumulator OPERA 81LITY is the accumulator pressure. A minimum accumulator pressure is specified, below which the capability of the accumulator to perform its intended function becomes degraded and the accumulator is g dered inoperable. The minimum accumulator pressure of umv stg is well below the expected pressure of 1750 psig (rte . 2).

Declaring the accumulator inoperable when the minimum pressure is not maintained ensures that significant ,

degradation in scram times does not occur. The 7 day Frequency has been shown to be acceptable through operating experience and takes into account indications available in the control room.

The Surveillance may be perfor1med in separate steps to prevent injecting baron into the RPV. An acceptable method for verifying flow from the pump to the RPV is to pump domineralized water from a test tank through one SLC subsystem and into the RPV. In order to pump this water, the test valve 1C41*F031 is open. A system initiation signal (which normally signals the 1C41*F001 storage tank suction valve) is generated with the test valve open and verification is made that the storage' tank suction valve I remains closed. The 18 month Frequency is based on the need to perform this Surveillance under the conditions that apply during a plant outage and the potential for an unplanned transient if the Surveillance were performed with the Operating experience has shown these reactor at power.

The LCO establishes operating limits that provide a margin to brittle failure of the reactor vessel and piping of the reactor coolant pressure boundary (RCPS). The vessel is the component most subject to brittle failure. Therefore, the LC0 liatts apply mainly to the vessel. 10 CFR 50, Appendix G (Ref. 1), requires the establishment of P/T limits for material fracture toughness requirements of the RCP8 materials. Reference 1 requires an adequate margin to brittle failure during nonnal operation, anticipated operational occurrences, and system hydrostatic tests. It mandates the use of the American Society of Mechanical Engineers (ASME) Code, Section III, Appendix G (Ref. 2). The actual shift in the RT,,, of the vessel material will be established periodically by removing and evaluating the irradiated reactor vessel material specimens, in accordance with ASTM E 185 (Ref. 3) and 10 CFR 50, Appendix H (Ref. 4).

I RCS P/T Limits B 3.4.11 BASES BACKGROUND The operating P/T limit curves will be adjusted, * (continued) as necessary, based on the evaluation findings and the recommendations of Reference 5. The P/T limit curves are composite curves established by superimposing limits derived from stress analyses of those portions of the reactor vessel and head that are the most restrictive. At any specific pressure, temperature, and temperature rate of change, one location within the reactor vessel will dictate the most restrictive limit. Across the span of the P/T limit curves, different locations are more restrictive, and, thus, the curves are composites of the most restrictive regions. 9e4 y ca_. _ ______,,__,___m,,_ __, ,,, ,, ,,,,,,,,,, h d hhh;h-h ,Eh'[ da]$. git [h = nbE ,

The consequence of violating the LCO limits is that the RCS has been operated under conditions that can result in brittle failure of the RCP8, possibly leading to a , nonisolable leak or loss of coolant accident. In the event these limits are exceeded, an evaluation must be performed to determine the effect on the structural integrity of the RCP8 components.

ATTACHMENT A (Bases 83.4.11, page B3.4-54) Figure 3.4.11-1 shows a set of F-T curves for the best-up and cool-down operating conditions at a given EFFY. These curves apply for both the %T and %T locations. When combining pressure and thermal stresses, it is usually necessary to evaluate stresses at the %T location (inside surface Haw) and the %T location (outside surface Haw). This is because the thensal gradient tensile stress oflaterest is in the inner wall during cool-down and is la the outer wau during best-up. However, as a conservative simpiincation, the thermal gradient stress at the %T is assumed to be tensile for both heat-up and cool-down. This resalts la the approach of applying the maximum tensile stress at the %T location. This approach is consenstive for two reasons: 1) the maximum stres is used regardless of Gaw location, and 2) the irradiation efects cause the nuoweble toughness, Kw at %T to be less than that at

 %T for a gives metal temperature. This approach causes no operational dimculties, since the BWR is at steam saturation conditions during normal operation, satisfying the best-up/ cool-dows curve limits.

RCS P/T Limits B 3.4.11 BASES APPLICABLE limits related to the P/T limits. Rather, the P/T limits , SAFETY ANALYSES are acceptance limits themselves since they preclude (continued) operation in an unanalyzed condition. RCS P/T limits satisfy Criterion 2 of the NRC Policy Statement. LCO The elements of this LC0 are:

a. RCS pressure, temperature, and heatup or cooldown rate are within the limits, during RCS heatup, cooldown, and inservice leak and hydrostatic testing.
b. The temperature difference b 4 een the reactor vessel bottom head coolant and the r . ctor pressure vessel (RPV) coolant is within the limit during recirculation pump startup, and during increases in THERMAL POWER or loop flow while operating at low THERMAL POWER or loop flow.
c. The temperature difference between the reactor coolant in the respective recirculation loop and in the reactor vessel meets the limit during recirculation pump startup, and during increases in THERMAL POWER or l loop flow while operating at low THERMAL POWER or loop flow.
d. RCS nra<<ues and temperature are within the l hereecQ ptinHtllimitspriortoachievingcriticality.
e. The reactor vessel flange and the head flange temperatures are within limits when tensioning the reactor vessel head bolting studs. ,

These limits define allowable operating regions and persit a large number of operating cycles while also providing a wide margin to nonductile failure.

This analysis assumes an initial maximum reactor steam dome pressure and evaluates the l response of the pressure relief system, primarily the safety / relief valves, during the limiting pressurization  ; transient. The determination of compliance with the overpressure criteria is dependent on the initial reactor steam dome pressure; therefore, the limit on this pressure ensures that the assumptions of the overpressure protectfos analysis are conserved. Reference 2 also assumes an initial reactor steam done pressure for the analysis of 08As and transients used to determine the i;mits for fuel cladding integrity MCPR (see Bases for LC0 3.2.2, " MINIMUM CRITICAL POWER RATIO (MCPR)") and 1% cladding plastic strain (see 8ases for LC0 3.2.1, " AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR)"). , Reactor steam dome pressure satisfies the requirements of Criterion 2 of the NRC Policy Statement. LCO The ecified reactor steam done pressure limit of 10 W psig ensures the plant is operated within the assumptions of the vessel overpressure protection analysis. Operation above the limit may result in a transient response more severe than analyzed. APPLICA81LITY In MODES 1 and 2, the reactor steam done pressure is required to be less than or equal to the limit. In these MODES, the reactor may be generating significant st m . and events which may challenge the overpressure limits are possible. (continued) 8 3.4-62 Revision No. 0 RIVER BEMO

In these MODES, the reactor - pressure is well below the required limit, and no anticipated events will challenge the overpressure limits. ACTIONS M With the reactor steam done pressure greater than the limit, prompt action should be taken to reduce pressure to below the limit and return the reactor to operation within the l bounds of the analyses.

This Completion Time also ensurus that the probability of an accident while pressure is greater than the limit is minimal. I M , If the reactor steam done pressure cannot be restored to within the limit within the associated Completion Time, the  ; plant must be brought to a MODE in which the LC0 does not apply. To achieve this status, the plant must be brought to . at least MODE 3 within 12 hours.

Main Turbine Bypass System B 3.7.5 B 3.7 PLANT SYSTEMS B 3.7.5 Main Turbine Bypass System BASES BACKGROUND The Main Turbine Bypass System is designed to control steam pressure when reactor steam generation exceeds turbine requirements during unit startup, sudden load reduction, and cooldown. It allows excess steam flow from the reactor to the condenser without goin hrough the turbine. The bypass capacity of the sys of the Nuclear Steam Supply Aem rated steam flow. udden load reductions within the 9' ga capacity of the steam bypass can be accommodated without reactor scram. The Main Turbine Bypass System consists of a two valve chest connected to the main steam lines between the main steam isolation valves and the turbine stop valves. Each of these valves is sequentially operated by hydraulic cylinders. The bypass valves are controlled by the pressure regulation function of the Turbine Pressure Regulator and Control System, as discussed in the USAR, Section 7.7.1.4 (Ref. 1). The bypass valves are normally closed, and the pressure regulator controls the turbine control valves, directing all steam flow to the turbine. If the speed governor or the load limiter restricts steam flow to the turbine, the pressure regulator controls the system pressure by opening the bypass valves. When the bypass valves open, the steam flows from the bypass chest, through connecting piping, to the pressure breakdown assemblies, where a series of orifices are used to further reduce the steam pressure before the steam enters the condenser. APPLICABLE The Main Turbine Bypass System is assumed to function during SAFETY ANALYSES the design basis feedwater controller failure, maximum demand event, described in the USAR, Section 15.1.2 (Ref. 2). Opening the bypass valves during the pressurization event mitigates the increase in reactor vessel pressure, wnich affects the MCPR during the event. An inoperable Main Turbine Bypass System may result in an MCPR penalty. The Main Turbine Bypass System satisfies Criterion 3 of the NRC Policy Statement.

[ l ENCLOSURE 4 ENTERGY OPERATIONS,INC. RIVER BEND STATION (RBS) ENVIRONMENTAL ASSESSMENT POWER UPRATE PROJECT Identification ofProposedAction River Bend Station (RBS) Unit 1 is currently licensed to operate at a core thermal power level of 2894 MWt. This proposed license amendment will increase the licensed core thermal power to 3039 MWt, or 105 percent of the current maximum steady state power level. Need for Proposed Action The proposed action permits an increase in the licensed core thermal power from 2894 MWt to 3039 MWt and provides the flexibility to increase the potential electrical output of RBS. Environmental Assessment of the Proposed Action The proposed amendment allowing power up-rate operation will not have a significant impact on the environment and does not constitute an un-reviewed environmental question. The radiological assessment of power up-rate operation is addressed in Enclosure and is summarized below. Details of the non-radiological assessment of the impact of power up-rate are provided. Radiological Environmental Assessment Adequate margin exists for the proposed power up-rate without exceeding regulatory limits for radiological effects. Power up-rate is not expected to have an adverse impact on the previous radiological environmental analyses; thus, revision of these analyses is not required. Existing Technical Specifications limits on radiological effluents will be maintained. Enclosure provides the power up-rate safety analyses report for RBS, as well as an l assessment of the radiological effects of power up-rate operation during both normal and i postulated accident conditions. Sections 8.1 and 8.2 discuss the potential effect of power l up-rate on the liquid and gaseous radwaste systems. Sections 8.3,8.4 and 8.5 discuss the 4 potential effect of power up-rate on radiation sources within the plant and radiation levels during normal and post-accident conditions. Section 9.2 presents the results of the  ! l calculated whole body and thyroid doses at the exclusion area boundary and the low population zone that might result from the postulated design basis radiological accidents. All offsite doses remain below established regulatory limits for power up-rate operation. l L

Non-Radiological Environment Assessment Since power up-rate will not significantly change the methods of generating electricity or of handling any influents from the environment or effluents to the environment, no new or different environmental impacts are expected. The detailed evaluation presented below conci des that non-radiological parameters affected by power up-rate will remain within the boundice conditions cited in the Final Environmental Statement (FES), which states that no significant environmental impact will result from operation of RBS. This conclusion remains valid for power up-rate. Note; The Environmental Report - Operating License Stage (ER-OLS), as part of the original application for the operating license for the operation of RBS, was for Units 1 and 2. The environmental impacts presented in this report were conservatively based on two-unit operation. The environmental operating permit applications and subsequent approved permits are also { based on two-unit operation. The cancellation of Unit 2 was not announced until January 5,1984. i The FES evaluated the non-radiological impact at a maximum design reactor power level of 2894 MWt per unit. The parameters evaluated in the Environmental Report and the subsequent FES (References 1 and 2) were re-evaluated at 3039 MWt to determine whether the proposed change is significant relative to adverse environmental impact (Env). The table provides a comparison of environmental-related operating parameters at I rated and up-rated power. Parameter Permit Level Current Uprated

OF 97/99 91/93 98.5 Chlorine mg/L 0.2 0 0 ave / day Note: Reference Enclosure 7 Table 6.2 The Circulating Water System design flow rate is the primary basis for determining makeup water for the cooling towers. Other factors affecting tower makeup are tower performance and meteorological conditions. Based on the review of cooling tower performance parameters associated with power up-rate, the design flow rate of the cooling towers will not change. Makeup requirements may increase slightly due to increased heat load on the towers and the associated increase in evaporation. The increase in makeup due to consumptive water use (evaporation) will not be significant and is enveloped by the river water withdrawal rates discussed in the FES and the rates approved in the current National Pollutant Discharge Elimination System (NPDES) and Louisiana Department of Enviromnental Quality (LADEQ) permits.

r: Changes in cooling tower blowdown rate and cooling tower chemistry as a result of the uprate are not significant. Any changes in blowdown rate and cooling tower cycles of concentration resulting from uprated power operation are enveloped by the existing

l. design criteria discussed in the FES.

l The losses or discharges to the atmosphere are n_ot o expected to be altered as a result of up- ! rate, except for evaporation from the cooling towers. As a result ofincreased heat rejection from the condensers, there will be an additional heat load on the cooling towers. For the same atmospheric conditions, there will be an increase in tower evaporation and drift. Due to this, there may be slight increases in drift deposition rates. Slight increases in evaporation and drift will not have any adverse environmental impacts nor will they afTect any environmental permits.

                                                                                                  ]

' l Cooling tower blowdown temperature associated with power uprate operation will increase slightly, thereby producing a slight increase in average and maximum river discharge temperature. A review of the increase in the river discharge temperature relative to the conclusions of the FES and thermal studies required to support licensing of the plant, indicates the slight temperature increase is not significant and is within the present permit limits. The slight temperature increase does not significantly impact the size of the thermal i mixing zone for the thermal effluent and does not alter the conclusions of the FES ' relative to thermal impacts. An application for a new Louisiana Pollutant Discharge , Elimination System (LPDES) has been submitted to LADEQ requesting an increase in average and maximum water discharge temperature due to present and future power up- ) rates. It is anticipated that this will be approved. No significant change in discharge flow rate, velocity, or chemical composition will occur due to the proposed power up-rate. Power rp-rate does not impact the discharge characteristics upon which the NPDES Permit is based. No notification, changes, or other action relative to the NPDES or LADEQ permits are required. No change in the groundwater withdrawal required to supply the RBS service water or fire protection system will result from the proposed up-rate. The evaluation also considered the flow rate required by the liquid radwaste system due to the proposed up-rate. No significant change in liquid radwaste quantities or activity le /els which would increase the required radwaste dilution flow are expected. 1 , l l l l l

Conclusions l EOI concludes that the proposed up-rate will not result in a significant adverse environmental J impact and is not an unreviewed environmental question. Based on the above evaluation, the plant operating parameters impacted by the proposed power up-rate remain within the bounding conditions on which the FES was based. The FES concluded that no significant environmental impact would result from the operation of RBS. This conclusion remains valid for power up-rate. Referencesi

(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), and l 2.790(d)(1) for " trade secrets and commercial or financial information obtained from l a person and privileged or confidential" (Exemption 4). The material for which l exemption from disclosure is here sought is all " confidential commercial l 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. 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 j propnetary information are:

a. Information that discloses a process, method, or apparatus, including supporting l 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; GBS-99-7-Af RiverBend PUP SAR. doc Affidavit Page 1

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; . l
                                                                    ~

! d. .Information which reveals aspects of past, present, or future General Electric customer-funded development plans and programs, of potential commercial value to General Electric; i e. Information which discloses patentable subject matter for which it may be i desirable to obtain patent protection. l Both the compilation as a whole and the marked independently proprietary elements incorporated in that compilation are considered proprietary for the reason described l in items (4)a. and (4)b., above. l (5) The information sought to be withheld is being submitted to NRC in confidence. That information (both the entire body of information in the form compiled in this j document, and the marked individual proprietary elements) is of a sort customarily  ! held in confidence by GE, and has, to the best of my knowledge, consistently been I held in confidence by GE, has not been publicly disclosed, and is not available in public sources. All disclosures to third parties including any required transmittals to l NRC, have been made, or must be_ made, pursuant to regulatory provisions or proprietary agreements which provide for maintenance of the information in i confidence. Its initial designation as proprietary information, and the subsequent j 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 j 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 i documents within GE 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 12 gal 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 by bars in the margin is classified as proprietary because it contains detailed results and conclusions from these evaluations, utilizing l analytical models and methods, including computer codes, which GE has developed, ) obtained NRC approval of, and applied to perform evaluations of transient and l accident events in the GE Boiling Water Reactor ("BWR"). The development and ) ! approval of these system, component, and thermal hydraulic models and computer { codes was achieved at a significant cost to GE, on the order of several million j dollars. l The remainder of the information identified in paragraph (2), above, is classified as proprietary because it constitutes a confidential compilation of information, including detailed results of analytical models, methods, and processes, including computer codes, and conclusions from these applications, which represent, as a whole, an integrated process or approach which GE has developed, obtained NRC approval of, and applied to perform evaluations of the safety-significant changes necessary to demonstrate the regulatory acceptability of a given increase in licensed power output for a GE BWR. The development and approval of this overall j approach was achieved at a significant additional cost to GE, in excess of a million l dollars, over and above the very large cost of developing the underlying individual proprietary analyses. l To effect a change to the licensing basis of a plant requires a thorough evaluation of the impact of the change on all postulated accident and transient events, and all other regulatory requirements and commitments included in the plant's FSAR. The I analytical process to perform and document these evaluations for a proposed power uprate was developed at a substantial investment in GE resources and expertise. The results from these evaluations identify those BWR systems and components, and those postulated events, which are impacted by the changes required to accommodate operation at increased power levels, and, just as importantly, those which are not so impacted, and the technical justification for not considering the latter in changing the licensing basis. The scope thus determined forms the basis for GE's offerings to support utilities in both performing analyses and providing licensing consulting services. Clearly, the scope and magnitude of effort of any attempt by a competitor to effect a similar licensing change can be narrowed considerably based upon these results. Having invested in the initial evaluations and developed the solution strategy and process described in the subject document GE derives an important competitive advantage in selling and performing these services. However, the mere knowledge of the impact on each system and component reveals the process, and provides a guide to the solution strategy. (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 availGility of profit-making opportunities. The information is part of GE's comprehensive BWR technology base, and its commercial value extends beyond the original i development cost. The value of the technology base goes beyond the extensive GBS-99-7-Af RiverBend PUP SAR. doc Affidavit Page 3

a 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, including justifications for not including certain analyses in applications to change the licensing basis. GE's competitive advantage will be lost if its competitors are able to use the results of the GE experience to avoid fruitless avenues, or to normalize or verify their own process, or to claim an equivalent understanding by demonstrating that they can arrive at the same or similar conclusions. In particular, the specific areas addressed by any document and submittal to support a change in the safety or licensing bases of the plant will clearly reveal those areas where detailed evaluations must be performed and specific analyses revised, and also, by omission, reveal those areas not so affected. While some of the underlying analyses, and some of the gross structure of the process, may at various times have been publicly revealed, enough of both the analyses and the detailed structural framework of the process have been held in confidence that this information, in this compiled form, continues to have great competitive value to GE. This value would be lost if the information as a whole, in the context and level of detail provided in the subject GE document, were to be disclosed to the public. Making such information available to competitors without their having been required to undertake a similar expenditure of resources, including that required to determine the areas that are not affected by a power uprate and are therefore blind alleys, would unfairly provide competitors with a windfall, and deprive GE of the opportunity to exercise its competitive advantagc to seek an adequate return on its large investment in developing its analytical process.
