Reactor Coolant System (RCS) Pressure versus Temperature limits during Heatup, Cooldown and Hydrostatic/Class I Leak Testing;2. RCS Heatup and Cooldown rates;3. Reactor Pressure Vessel (RPV) to RCS coolant AT requirements during Recirculation Pump startups;4. RPV bottom head coolant temperature to RPV coolant temperature AT requirements during Recirculation Pump startups;5. RPV head flange bolt-up temperature limits.This report has been prepared in accordance with the requirements defined in Reference 6.2.2.0 Applicability This report is applicable to the BFNP Unit 1 RPV for up to 25 and 38 Effective Full Power Years (EFPY), representing a 60-year license.The following Technical Specification (TS) is affected by the information contained in this report: TS 3.4.9 RCS Pressure and Temperature (P/T) Limits 3.0 Methodology The limits in this report were derived from the Nuclear Regulatory Commission (NRC)-approved methods listed in the specific revisions listed below: 1. The neutron fluence was calculated per Licensing Topical Report (LTR), General Electric Methodology for Reactor Pressure Vessel Fast Neutron Flux Evaluation, NEDC-32983P-A, Revision 2, January 2006, approved in Reference 6.1.2. The pressure and temperature limits were calculated per GE Hitachi Nuclear Energy Methodology for Development of Reactor Pressure Vessel Pressure-Temperature Curves, NEDC-33178P-A, Revision 1, June 2009, approved in Reference 6.2.3. This revision of the pressure and temperature limits is to incorporate the following changes:* Application of GEH Topical Report for Pressure-Temperature (P-T)Curves* The Water Level Instrumentation (WLI) nozzle that occurs in the beltline region was fabricated from non-ferritic Inconel material and has been considered in the Adjusted Reference Temperature (ART) evaluation.
The 1 NEDO-33445 Revision 0 Non-Proprietary Information-Class I (Public)material properties of the [[ 1] material have been considered with the fluence for the nozzle location.Application of new Integrated Surveillance Program (ISP) testing and analysis results from the BFNP Unit 2 surveillance capsule that are applicable to BFNP Unit 1.3.1 Chemistry The N16 WLI nozzle is defined as being within the beltline region, and is evaluated for ART.This nozzle is fabricated from non-ferritic Inconel materials.
Therefore, the chemistry for the R]] to evaluate the ART to represent this nozzle forging.Chemistry for all other materials remains unchanged from those used in the development of the currently licensed P-T curves.Surveillance materials are evaluated using the chemistries obtained from Boiling Water Reactor (BWR) Vessel and Internals Project (BWRVIP)-135, Revision 2, as presented in Section 3.4. It is noted that there are no best estimate chemistries for the BFNP Unit 1 beltline materials described in BWRVIP-135.
The Chemistry Factors (CFs) for all materials are calculated based upon the requirements of Regulatory Guide (RG) 1.99, Revision 2.3.2 Initial Reference Temperature of Nil Ductility Transition The N 16 WLI nozzle is evaluated for ART. As the nozzle forging is fabricated from Inconel, for which fracture toughness evaluations are not required, the [[1] are used.Surveillance materials are evaluated using the limiting initial RTNDT of the beltline plate or weld material.Initial RTNDTS for all other beltline materials remain unchanged from those used in the development of the currently licensed P-T curves.3.3 Adjusted Reference Temperature The ART values for 25 and 38 EFPY included in Appendix B are developed considering the latest BWRVIP ISP data available that is representative of the applicable materials in the BFNP Unit I RPV (Reference 6.3). The surveillance data used in the BFNP Unit I ART calculations are not obtained from actual BFNP Unit 1 RPV test specimens.
The ISP plate materials are not limiting with respect to the ART. The ISP weld is the limiting material; this value is considered in the development of the P-T curves because the ISP material is the identical heat to the material in the BFNP Unit I RPV.The N 16 nozzle ART is determined considering the initial RTNDT E[]material together with the fluence at the nozzle elevation.
2 NEDO-33445 Revision 0 Non-Proprietary Information-Class I (Public)3.4 Surveillance Program As discussed in Appendix A, BFNP Unit 1 participates in the ISP. All three (3) of the surveillance capsules, installed at plant startup, remain in the vessel. As BFNP Unit 1 is not a host plant, the three (3) surveillance capsules have an ISP status designation of deferred (standby) per Reference 6.4.BWRVIP-135, Revision 2 and Reference

Level C and Level D Service Limits should be evaluated on an individual case basis (G-2300)." As described in Section 4.3 of Reference 6.1, [[ ]] the development of all non-beltline PT limits.ASME Section III, Paragraph NB-2332 states that "Pressure-retaining materials (other than bolting) with nominal thickness over 2.5 inches for piping (pipe and tubes) and materials for pumps, valves and fittings with any pipe connection of nominal wall thickness greater than 2.5 inches shall meet the requirements of NB-233 1. The lowest service temperature shall be not lower than RTNDT + 100°F unless a lower temperature is justified by following the methods similar to those contained in Article G-2000." All BFNP Unit 1 ferritic Reactor Coolant Pressure Boundary (RCPB) piping has nominal wall thicknesses less than 2.5 inches. Other Class 1 RCPB components are significantly smaller with nominal wall thicknesses well below 2.5 inches, including all of the ferritic RCPB components.
The lowest service temperatures may be less than 250'F in some cases; however the methods of Appendix G have been followed to justify lower temperatures.
Therefore, the requirements of NB-2332 have been met, and there are no ferritic RCPB piping components that require consideration in the RPV P-T curves for BFNP Unit 1.4 NEDO-33445 Revision 0 Non-Proprietary Information-Class I (Public)The [[]], are more limiting relative to stress than any of the Class 1 ferritic branch piping in the RCPB.With respect to concern regarding irradiation effects on RCPB piping, a qualitative fluence assessment was performed.
With a 38 EFPY peak surface Inside Diameter (ID) fluence of 1.58e18 n/cm 2 as the maximum fluence of concern, accrual of fluence greater than 1.Oel 7 n/cm 2 outside the vessel for 38 EFPY is not expected, based on historical calculations of flux vs. vessel thickness.
As discussed in the BFNP Updated Final Safety Analysis Report (UFSAR), it is noted that the manner in which the RCPB was designed and constructed was to ensure a high degree of integrity with adequate toughness throughout the plant life. The RCPB components were designed and fabricated, and are maintained and tested such that adequate assurance is provided that the boundary will behave in a non-brittle manner throughout the life of the plant.3.6 Future Changes Changes to the curves, limits, or parameters within this PTLR, based upon new irradiation fluence data of the RPV, or other plant design assumptions in the UFSAR, can be made pursuant to 10 CFR 50.59, provided the above methodologies are utilized.
The revised PTLR shall be submitted to the NRC upon issuance.4.0 Operating Limits The P-T curves provided in this report represent steam dome pressure versus minimum vessel metal temperature and incorporate the appropriate non-beltline limits and irradiation embrittlement effects in the beltline region.The operating limits for pressure and temperature are required for three categories of operation: (a) hydrostatic pressure tests and leak tests, referred to as Curve A; (b) non-nuclear heatup/cooldown (core not critical), referred to as Curve B; and (c) core critical operation, referred to as Curve C.Complete P-T curves were developed for 25 and 38 EFPY. The P-T curves are provided in Figures 1 through 4, and a tabulation of the curves is included in Table 1 (25 EFPY) and Table 2 (38 EFPY).Other temperature limits applicable to the RPV and controlled by the Technical Specification are: " Heatup and Cooldown rate limit during Hydrostatic and Class 1 Leak Testing:< 15'F/hour." Normal Operating Heatup and Cooldown rate limit: __ 100lF/hour.

===6.2. Initial===
RTNDT values for all vessel materials considered are presented in tables in Appendix B of this report.In order to ensure that the limiting vessel discontinuity has been considered in the development of the P-T curves, the methods in Sections 4.3.2.1 and 4.3.2.2 of Reference 6.2 for the non-beltline and beltline regions, respectively, are applied.In order to determine how much to shift the P-T curves, an evaluation is performed using Tables 4-4a and 4-5a from NEDC-33178P-A (Reference 6.2). These tables define the [[]] curves.Each component listed in these tables is [[ ]] for each component.
The required temperature is then determined by [[]], thereby resulting in the required T for the curve. As the upper vessel curve is initially based on the [[ ]] T-RThNyT, all resulting T values are compared to the [[ ]]. The [[]] the upper vessel curve. The same method is applied for the [[ ]] curve. In this manner, it is assured that each curve bounds the[]] that is represented.
For the BFNP Unit 1 upper vessel curve, the maximum T value from the method described above is [[ ]]. The initial required T-RTN-oT for the U]]; this is then adjusted by the BFNP Unit 1-specific
[R ]], resulting in [[Comparing this to the other components bounded by the upper vessel curve, the limiting value is for the [[ ]]. The required T-RTNDT for the [[]], which is [[ ]]. It is seen that the resulting T required for the [[ ]]. As [[ ]] is limiting, the BFNP Unit 1 upper vessel curve is based on an RTNDT of [[]]. As noted above, this calculation was performed for each component shown in Table 4-4a of NEDC-33178P-A (Reference 6.2); only the limiting cases are presented here.For the BFNP Unit 1 bottom head or CRD [[]], the maximum T value from the method described above is [[]]. The required T-RTNDT for the EE]]; this is adjusted by the BFNP Unit 1-specific maximum [[]], resulting in [[ ]]. Comparing this to the next limiting value, the 6 NEDO-33445 Revision 0 Non-Proprietary Information-Class I (Public)required T-RTNDT is [[ ]], which is added to the [[]]. It is seen that the resulting T required for the [[ ]]. As[[i ]], the BFNP Unit 1 bottom head (CRD) curve is based on an E[[ ]]. As noted above, this calculation was performed for each component shown in Table 4-5a of NEDC-33178P-A (Reference 6.2); only the limiting case is presented here.Appendix H of NEDC-33178P-A (Reference 6.2) contains the details of an analysis performed to determine the baseline requirement (non-shifted) for the [[]]. It can be seen in Section H.5 of Appendix H that the stresses developed in this finite element analysis demonstrated that the 11 11, resulting in a baseline non-shifted required T-RTNDT of []]. Therefore, considering the determination of the required shift from the paragraph above for [[ ]], calculations for all components listed in Table 4-5a of NEDC-33178P-A were compared to the CRD T, which is [[ ]] (where [[]] materials).
Therefore, the shift for the bottom head [.For BFNP Unit 1, the limiting surveillance material, E[ ]], was considered using [[ ]] as defined in Appendix I of Reference 6.2. This procedure was used because the target vessel material and the surveillance material [[ ]]. As this material is a [[ ]], the use of the [[]] is considered.
The calculated value of [l]] material for the beltline P-T curves.For BFNP Unit 1, there are thickness discontinuities in the vessel: (1) between the bottom head upper and lower torus; and (2) between the bottom head torus and the support skirt attachment.
The P-T curves defined in Section 4.3 of Reference 6.2 are based upon an RTNDT of 56'F for the bottom head [[ ]], and 51 'F for the upper vessel. The 25 EFPY beltline curves are based on an ART of 128'F, and the 38 EFPY beltline curves are based on an ART of 146'F. Curves based on these temperatures bound the requirements due to the beltline thickness discontinuities.
The ART of the limiting beltline material is used to adjust the beltline P-T curves to account for irradiation effects. RG 1.99, Revision 2 provides the methods for determining the ART. The basis for the difference in the margin terms in Tables B-4 and B-5 is due, in part, to the effective fluence associated with 25 and 38 EFPY. For many of the BFNP Unit 1 materials, the margin term is dependent on the ARTNDT. This is consistent with Position 1.1 of RG 1.99, Revision 2, which provides the methodology for determining ART. The final paragraph of this section of the RG states that aA (standard deviation for ARTNDT) is 17 0 F for plates and 28'F for welds, but that aA need not exceed 0.5*ARTNDT.
The BFNP Unit 1 ART calculation has incorporated the use of 7 NEDO-33445 Revision 0 Non-Proprietary Information-Class I (Public)0.5*ARTND-for all materials, where applicable.
The full margin term was used for the [[The vessel beltline copper and nickel values were obtained from plant-specific vessel purchase order records, Certified Material Test Reports (CMTRs), or are values previously approved by the NRC, and remain unchanged from previous submittals.
The pressure head for the beltline hydrostatic test curve (Curve A) for BFNP Unit 1 is[[ ]]. This is determined using the height of the vessel and the elevation of the bottom of active fuel. The full vessel pressure head is [[ ]]. This pressure is used in the P-T curve analysis, considered in the determination of KI for the bottom head curve as discussed in Sections 4.3.2.1.1 and 4.3.2.2.2 of the LTR.The P-T curves for the non-beltline region were conservatively developed for a BWR [[]] with nominal ID of [[ ]]. As discussed in Section 4.3.2.1.1 of the LTR, if the plant-specific result of Equation 4-3 is greater than that of the [[ ]]from Equation 4-2, the user is directed to perform a plant-specific evaluation.
The plant-specific BFNP Unit 1 geometry demonstrates that it is bounded by the Equation 4-2 result: BFNP Unit 1: R / t1/2 = [[ ]]The analysis is therefore considered appropriate for BFNP Unit 1. The [[ ]] was adapted to the conditions at BFNP Unit 1 using plant-specific RTNDT values for the RPV.The peak RPV ID fluence used in the P-T curve evaluation for BFNP Unit 1 at 25 EFPY is 1.01 e 18 n/cm 2 and at 38 EFPY is 1.58e18 n/cm 2.These values were calculated using methods that comply with the guidelines of RG 1.190, (as discussed in Reference 6.1). This fluence applies to the lower-intermediate shell plates and longitudinal welds. The fluence is adjusted for the lower plates, associated longitudinal welds, and the girth weld based upon the axial fluence distribution calculated as part of the fluence evaluation; hence, the peak ID surface fluence for these components is 8.14e17 n/cm 2 for 25 EFPY and 1.28e18 n/cm 2 for 38 EFPY. Similarly, the fluence is adjusted for the N16 nozzle based upon the axial fluence distribution; hence, the peak ID surface fluence used for this component is 3.04e1 7 n/cm 2 for 25 EFPY and 4.77e1 7 n/cm 2 for 38 EFPY.The P-T curves for the heatup and cooldown operating conditions at a given EFPY apply for both the 1/4T and 3/4T locations.
When combining pressure and thermal stresses, it is usually necessary to evaluate stresses at the 1/4T location (inside surface flaw) and the 3/4T location (outside surface flaw). This is because the thermal gradient tensile stress of interest is in the inner wall during cooldown and the outer wall during heatup. However, as a conservative simplification, the thermal gradient stress at the l/4T location is assumed to be tensile for both heatup and cooldown.
This results in the approach of applying the maximum tensile stress at the 1/4T location.
This approach is conservative because irradiation effects cause the allowable toughness, KI, at 1/4T to be less than that at 3/4T for a given metal temperature.
This approach causes no operational difficulties, because the BWR is at steam saturation conditions during normal operation, well above the heatup/cooldown curve limits.8 NEDO-33445 Revision 0 Non-Proprietary Information-Class I (Public)For the core not critical curve (Curve B) and the core critical curve (Curve C), the P-T curves specify a coolant heatup and cooldown temperature rate of < 1000F/hr for which the curves are applicable.
However, the core not critical and the core critical curves were also developed to bound transients defined on the RPV thermal cycle diagram and the nozzle thermal cycle diagrams.
For the hydrostatic pressure and leak test curve (Curve A), a coolant heatup and cooldown temperature rate of < 15&deg;F/hr must be maintained.
The P-T limits and corresponding heatup/cooldown rates of either Curve A or B may be applied while achieving or recovering from test conditions.
Curve A applies during pressure testing and when the limits of Curve B cannot be maintained.
As shown in Tables B-4 and B-5, the [[]]. However, the material is contained in the [[]]. When comparing the required T-RTNDT for the [[]] provides a more restrictive curve. This is due to the reduced [[]] as discussed in Section 4.3.2.2.2 of the LTR. Therefore, for BFNP Unit 1, the axial electroslag weld heat is the limiting material for the beltline region for 25 and 38 EFPY. The initial RTNDT for electroslag weld heat material is 23.1 OF. The generic pressure test P-T curve is applied to the BFNP Unit I beltline curve by shifting the P vs. (T -RTNDT) values to reflect the ART value of 128&deg;F for 25 EFPY and 146 0 F for 38 EFPY.Using the fluence discussed above, the P-T curves are beltline limited for Curves A, B, and C, for 25 and 38 EFPY. For 25 EFPY, Curve A is beltline limited above 640 psig; Curve B and Curve C are beltline limited above 500 psig. For 38 EFPY, Curve A is beltline limited above 570 psig; Curve B and Curve C are beltline limited above 410 psig and 420 psig, respectively.
For Curve C, the upper vessel and beltline regions are bounding at pressures up to 50 psig. For pressures between 60 psig and 312.5 psig, the upper vessel is bounding; this is true for both 25 and 38 EFPY.The N16 WLI nozzle is a partial penetration design similar to that shown in Figure 1 in Appendix J of the LTR, fabricated with a [[ ]]. Reference to this status is contained in the BFNP UFSAR. Therefore, the evaluation is performed, consistent with the statement in Appendix J, [[]]. Appendix J of the LTR provides detailed results of an analysis performed for the WLI nozzle that provides the [[]] a specific curve applicable for the WLI nozzle to ensure that this location is bounded in the P-T curves.

All three capsules have been in the reactor vessel since plant startup.As described in the BFNP Unit 1 UFSAR Section 4.2.6, Inspection and Testing, the BWRVIP ISP will determine the removal schedule for the remaining BFNP Unit 1 surveillance capsules.The BFNP Unit 1 material surveillance program is administered in accordance with the BWRVIP ISP. The ISP combines the United States (US) BWR surveillance programs into a single integrated program. This program uses similar heats of materials in the surveillance programs of BWRs to represent the limiting materials in other vessels. It also adds data from the BWR SSP. Per the BWRVIP ISP, BFNP Unit 1 is not a host plant; all surveillance capsules are classified as "Deferred".

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 that, if used by a competitor, would reduce their expenditure of resources or improve their competitive position in the design, manufacture, shipment, installation, assurance of quality, or licensing of a similar product;c. Information that reveals aspects of past, present, or future GEH customer-funded development plans and programs, resulting in potential products to GEH;d. Information that discloses trade secret or potentially patentable subject matter for which it may be desirable to obtain patent protection.
(5) To address 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 GEH, Page 1 of 3 GE-Hitachi Nuclear Energy Americas LLC 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, not been disclosed publicly, and not been made 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 or confidentiality agreements that provide for maintaining the information in confidence.
The initial designation of this information as proprietary information, and the subsequent steps taken to prevent its unauthorized disclosure, are as set forth in the following paragraphs (6) and (7).(6) Initial approval of proprietary treatment of a document is made by the manager of the originating component, who is the person most likely to be acquainted with the value and sensitivity of the information in relation to industry knowledge, or who is the person most likely to be subject to the terms under which it was licensed to GEH. Access to such documents within GEH is limited to 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 or confidentiality agreements.
(8) The information identified in paragraph (2), above, is classified as proprietary because it contains the detailed GEH methodology for pressure-temperature curve analysis for the GEH Boiling Water Reactor (BWR). These methods, techniques, and data along with their application to the design, modification, and analyses associated with the pressure-temperature curves were achieved at a significant cost to GEH.The development of the evaluation processes along with the interpretation and application of the analytical results is derived from the extensive experience databases that constitute 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 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 Page 2 of 3 GE-Hitachi Nuclear Energy Americas LLC 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 6 th day of December 2013.Peter M.

("EPRI") and I have been specifically delegated responsibility for the above-listed report that contains EPRI Proprietary Information that is sought under this Affidavit to be withheld ("Proprietary Information").
I am authorized to apply to the U.S. Nuclear Regulatory Commission
("NRC") for the withholding of the Proprietary Information on behalf of EPRI.EPRI Information is identified by a solid underline inside double square brackets.
[[This sentence is an example. ]{E} Tables containing EPRI proprietary information are identified with double square brackets before and after the object. In each case the superscript notation {E} refers to this affidavit as the bases for the proprietary determination.
EPRI requests that the Proprietary Information be withheld from the public on the following bases: Withholding Based Upon Privileged And Confidential Trade Secrets Or Commercial Or Financial Information (see e.,g. 10 C.F.R. &sect;2.390(a)(4):
: a. The Proprietary Information is owned by EPRI and has been held in confidence by EPRI. All entities accepting copies of the Proprietary Information do so subject to written agreements imposing an obligation upon the recipient to maintain the confidentiality of the Proprietary Information.
The Proprietary Information is disclosed only to parties who agree, in writing, to preserve the confidentiality thereof.b. EPRI considers the Proprietary Information contained therein to consitiute trade secrets of EPRI. As such, EPRI holds the Information in confidence and disclosure thereof is strictly limited to individuals and entities who have agreed, in writing, to maintain the confidentiality of the Information.
: c. The information sought to be withheld is considered to be proprietary for the following reasons. EPRI made a substantial economic investment to develop the Proprietary Information and, by prohibiting public disclosure, EPRI derives an economic benefit in the form of licensing royalties and other additional fees from the confidential nature of the Proprietary Information.
If the Proprietary Information were publicly available to consultants and/or other businesses providing services in the electric and/or nuclear power industry, they would be able to use the Proprietary Information for their own commercial benefit and profit and without expending the substantial economic resources required of EPRI to develop the Proprietary Information.
: d. EPRI's classification of the Proprietary Information as trade secrets is justified by the Uniform Trade Secrets Act which California adopted in 1984 and a version of which has been adopted by over 40 states. The California Uniform Trade Secrets Act, California Civil Code &sect;&sect;3426 -3426.11, defines a "trade secret" as follows: "Trade Secret" means information, including a formula, pattern, compilation, program device, method, technique, or process, that: (1) Derives independent economic value, actual or potential, from not being generally known to the pubic or to other persons who can obtain economic value from its disclosure or use; and (2) is the subject of efforts that are reasonable under the circumstances to maintain its secrecy." e. The Proprietary Information contained therein are not generally known or available to the public. EPRI developed the Information only after making a determination that the Proprietary Information was not available from public sources. EPRI made a substantial investment of both money and employee hours in the development of the Proprietary Information.
EPRI was required to devote these resources and effort to derive the Proprietary Information.
As a result of such effort and cost, both in terms of dollars spent and dedicated employee time, the Proprietary Information is highly valuable to EPRI.f. A public disclosure of the Proprietary Information would be highly likely to cause substantial harm to EPRI's competitive position and the ability of EPRI to [icense the Proprietary Information both domestically and internationally.
The Proprietary Information can only be acquired and/or duplicated by others using an equivalent investment of time and effort.I have read the foregoing and the matters stated herein are true and correct to the best of my knowledge, information and belief. I make this affidavit under penalty of perjury under the laws of the United States of America and under the laws of the State of California.
