October 3,2003 NRC:03:067 Document Control Desk ATTN: Chief, Planning, Program and Management Support Branch U.S. Nuclear Regulatory Commission Washington, D.C. 20555-0001 Catawba Nuclear Station and McGuire Nuclear Station, Partial Response to Request for Additional Information Regarding Use of Mixed Oxide Lead Fuel Assemblies.

Ref.: 1. William B. McGuire Nuclear Station Units 1 and 2 and Catawba Nuclear Station Units and 2: Mixed Oxide Lead Fuel Assemblies (TAC Nos. MB7863, MB7864, MB7865, and MB7866), Request for Additional Information, July 25, 2003.

In Reference 1, the NRC requested additional information to facilitate the completion of its review of the Duke Power Corporation license amendment request (LAR) for mixed oxide (MOX) fuel. In response to this request, Framatome ANP submits the enclosed information to support the NRC's review of the deterministic LOCA analyses for MOX fuel related to the Duke Power LAR. This submittal, which includes selected input decks, is made at the request of Duke Power and supports the response to Question 13 in the NRC's request for additional information. to this letter provides a supplementary response to Question 13 of the RAI contained in Reference 1.

One CD containing the proprietary information is enclosed. Framatome ANP considers the material contained in the enclosed documents to be proprietary. As required by 10 CFR 2.790(b), an affidavit is enclosed to support the withholding of the information from public disclosure. The entire input deck is considered proprietary and therefore a non-proprietary version will not be included with this letter.

Document Control Desk NRC:03:067 October 3, 2003 Page A-1 ATTACHMENT 1 Question 13 of Reference 1 states:

aTo allow the NRC staff to perform confirmatory analysis, please provide both the McGuire and Catawba loss-of-coolant (LOCA) input decks for the low enriched uranium (LEU) as well as the MOX fuel rods. Provide the decks in an electronic format, including nodalization diagrams."

Response

The accompanying CD includes two RELAP5IMOD2-B&W input decks in UNIX format. These decks describe the modeling for the deterministic evaluations of the MOX and LEU fuel pins reported in Duke's licensing amendment request (LAR). The deterministic LEU calculations within the LAR were performed to determine the relative differences in LOCA performance between MOX and LEU fuel. The licensing calculations of record for the LEU fuel is performed with a Westinghouse realistic model not the Framatome ANP LEU deterministic model provided herein.

2. r5uo2nrc.in Blowdown input deck for LEU fuel pins.

RELAP5/MOD2-B&W (BAW-10164PA) is a derivative of RELAP5/MOD2. Because the input for this version may not be recognizable by other versions of RELAP5, the following list of related input card images is provided to assist in resolving run difficulties.

Card 190: EM Choking Model Specification Card (Activates Framatome ANP specific choked flow break modeling.)

1.

My name is Gayle F. Elliott. I am Manager, Product Licensing, for Framatome ANP ("FANP"), and as such I am authorized to execute this Affidavit.

2.

1 am familiar with the criteria applied by FANP to determine whether certain FANP information is proprietary. I am familiar with the policies established by FANP to ensure the proper application of these criteria.

3.

1 am familiar with the FANP information in the enclosure, "Input Decks for the Deterministic LOCA Analysis for MOX and LEU Fuel", and referred to herein as "Document."

Information contained in this Document has been classified by FANP as proprietary in accordance with the policies established by FANP for the control and protection of proprietary and confidential information.

4.

This Document contains information of a proprietary and confidential nature and is of the type customarily held in confidence by FANP and not made available to the public.

Based on my experience, I am aware that other companies regard information of the kind contained in this Document as proprietary and confidential.

5.

This Document has been made available to the U.S. Nuclear Regulatory Commission in confidence with the request that the information contained in the Document be withheld from public disclosure.

The following criteria are customarily applied by FANP to determine whether information should be classified as proprietary:

(a)

The information reveals details of FANP's research and development plans and programs or their results.

(b)

Use of the information by a competitor would permit the competitor to significantly reduce its expenditures, in time or resources, to design, produce, or market a similar product or service.

(c)

The information includes test data or analytical techniques concerning a process, methodology, or component, the application of which results in a competitive advantage for FANP.

(d)

The information reveals certain distinguishing aspects of a process, methodology, or component, the exclusive use of which provides a competitive advantage for FANP in product optimization or marketability.

(e)

The information is vital to a competitive advantage held by FANP, would be helpful to competitors to FANP, and would likely cause substantial harm to the competitive position of FANP.
