By letters dated June 28, 2004 and June 25, 2004 (ADAMS Accession Nos.

ML041840109 and ML041840301),

TVA submitted license amendment applications to the NRC for the EPU of BFN Unit 1 and BFN Units 2 and 3, respectively.

The proposed amendments would change the operating licenses to increase the maximum authorized core thermal power level of each reactor by approximately 14 percent to 3952 megawatts.

On December 14, 2007, the NRC staff issued a Round 15 RAI (ML073450725) regarding the EPU license amendment requests. to this letter provides TVA's responses to the Round 15 RAI questions APLA-38/40, SRXB-71, and SRXB-72.

The remaining Round 15 RAI questions are exclusively related to steam dryers.

As indicated in TVA's December 14,

2008, letter to NRC (ML0735101801) regarding steam dryer analysis schedules, TVA plans to provide a response to the Round 15 steam dryer RAIs by January 31, 2008, which will include a schedule for responding to the remainder of the RAIs.

RESPONSE TO ROUND 15 REQUEST FOR ADDITIONAL INFORMATION APLA-38/40, SRXB-71, and SRXB-72 (NON-PROPRIETARY INFORMATION VERSION)

This enclosure provides TVA's response to NRC's December 14,

2007, Round 15 Request for Additional Information (RAI) questions APLA-38/40, SRXB-71, and SRXB-72.

NON-PROPRIETARY VERSION NRC RAI APLA-38/40 In the human reliability analysis, there are two operator actions related to depressurization following a failure of high pressure coolant injection (HPCI) and reactor core injection cooling (RCIC):

HPRVD1,"Operator fails to depressurize given HPCI/RCIC hardware failed (OHPR=S),"

apparently addresses HPCI/RCIC failure to due hardware failure.

This event has a Fussell-Vesely importance of about 0.2 for Unit 2 and about 0.3 for Unit 3, and a risk achievement worth (RAW) of about 1560 for Unit 2 and about 864 for Unit 3.

ORVD2, "Operator fails to depressurize given HPCI/RCIC hardware failed (OHPR=F),"

apparently addresses HPCI/RCIC failure due-to an operator control failure.

This event has a Fussell-Vesely importance of about 0.13 for Unit 2 and about 0.07 for Unit 3, and a RAW of about 1.8 for Unit 2 and about 1.4 for Unit 3.

Address why these two events do not have similar RAW values.

Briefly discuss how these events are incorporated into the probabilistic risk assessment logic structure, and how the RISKMAN software computes Fussell-Vesely important measures and RAWs.

TVA Response to APLA-38/40 Action Discussion Operator manual action HPRVD1 models one of two aspects of manual depressurization of the reactor pressure vessel (RPV).

For HPRVD1, initial operation of high pressure injection sources has been successful, but the high pressure injection (HPI) sources subsequently fail in the longer term such that manual RPV depressurization is required later in the event sequence to allow utilization of low pressure injection (LPI) systems.

Operator manual action ORVD2 models the other aspect of RPV manual depressurization.

For ORVD2,: initial operation of high pressure injection sources fails and manual RPV depressurization is required early in the event sequence to allow utilization of LPI sources.

In both cases, the manual depressurization action is accomplished in the same way, by opening main steam safety/relief valves via operation of the main control room E2-1

NON-PROPRIETARY VERSION panel handswitches.

However, because the event situations under which this action is required are markedly different, the failure probabilities of the two situations are also markedly different.

For HPRVD1, since HPI is initially successful, the subsequent failure occurs when initial reactor water levels are relatively high and the core decay heat has decreased.

So the rate of water level loss is lower and significantly longer time is available to identify the need for manual RPV depressurization and to accomplish this depressurization.

The probability of failure of this action is assessed in the BFN model probabilistic risk assessment (PRA) as 1.9E-04 (i.e., 1 failure in 5263 demands).

For ORVD2, since HPI fails initially, no significant sources of injection are available to provide core cooling.

Core decay heat is high and water inventory is lost at a rapid rate.

A relatively short time is available for the operator to identify, diagnose and respond with very little allowance for recovery.

The probability of failure of this action is assessed in the BFN PRA model as 1.4E-01 (i.e., 1 failure in 7 demands).

PRA Logic Structure Incorporation A complete presentation of all factors impacting the risk importance of operator actions HPRVDI and ORVD2 would be impractical to present here, however, the following simplified event tree below illustrates the fundamental relationships between high HPI, manual depressurization operator actions, and LPI.

E2-2

-5 success I-6 core damage 7 core damage 8 success 9 core damage Sequences 1, 2, and 5 above result in successful event mitigation, wherein HPI was successful, or successful manual depressurization together with successful LPI occurred.

Sequences 3, 4,

6, and 7 result in core damage, because HPI failed (either short or long term) and successful manual depressurization together with successful LPI did not occur.

Sequences 8 and 9, included here for completeness, do not involve HPI or manual depressurization, but rather depend on LPI success.

From inspection of the above event tree, it can be seen that ORVD2 is only questioned if short term HPI has failed, and since HPI reliability is good, ORVD2 plays no role in most sequences.

HPRVD1 is questioned, however, if long term HPI fails, therefore HPRVD1 will be involved in a greater number of event sequences.

Because HPRVD1 appears in a greater number of event sequences and because its actual failure probability is low, arbitrarily setting its failure rate to 100% for purposes of the RAW calculation will significantly impact the Core Damage Frequency (CDF) calculation, resulting in a large RAW value.

Conversely, since ORVD2 appears in fewer sequences and its actual failure probability is high, the arbitrary setting of its failure rate to 100% will have a smaller impact on the CDF calculation resulting in a smaller RAW value.

• R( 1 ) is the total CDF as calculated with the split fraction of interest fixed at 1.0 (i.e.,

failure probability of 100%)

" R(fi) is the total CDF as calculated with the split fraction of interest left at its nominal probabilistic value Fussel-Vesely (FVI)

" R(1 ) is the total CDF as calculated with the split fraction of interest fixed at 1.0

" R(0) is the total CDF as calculated with the split fraction of interest fixed at 0.0 (i.e.,

failure probability of 0%)

" fi is the split fraction's nominal probabilistic value

• R(fi) is the total CDF as calculated with the split fraction of interest left at its nominal probabilistic value E2-4

NON-PROPRIETARY VERSION NRC RAI SRXB-71 (Unit 1 only)

Provide the Cycle 8 core load map and a description of each type of bundle that will be used.

TrVA Response to SRXB-71 (Unit 1 only)

See the following Cycle 8 quarter core maps and bundle descriptions.

The core loading and bundle designs are representative of typical reload cores.

The design and quantity of each type of fresh fuel bundle are set.

The core loading map is from the fuel cycle analysis used to release the Cycle 8 fresh fuel for fabrication.

It should be noted that the final locations of the bundles could differ slightly between the fuel cycle loading and the final Reference Loading Pattern.

RESPONSE TO ROUND 15 REQUEST FOR ADDITIONAL INFORMATION APLA-38/40, SRXB-71, and SRXB-72 AFFIDAVIT This enclosure provides GNF's affidavit for Enclosure P.

Global Nuclear Fuel - Americas AFFIDAVIT I, Anthony P. Reese, state as follows:

(1) I am Reload Licensing Manager, Fuel Engineering, Global Nuclear Fuel-Americas, LLC

("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, "NRC Requests for Additional Information (RAIs) for Browns Ferry I Cycle 8 Shut Down Margin Designs" dated January 4, 2008. GNF proprietary information is identified by a dotted underline inside double square brackets.

((Thi.s... sentence is an examp..e..]

In each case, the superscript notation p3 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" (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 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 aspects of past, present, or future GNF-A customer-funded development plans and programs, resulting in potential products to GNF-A;

d.

Information which discloses patentable subject matter for which it may be desirable to obtain patent protection.

Affidavit Page 1 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 2.390 (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. 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. 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 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.

Affidavit Page 2 of 3

(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 information 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.

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 on this 4th day of January 2008.
