Subject:
Catawba Nuclear Station Units 1 and 2; Docket Nos. 50-413, 50-414 McGuire Nuclear Station Units 1 and 2; Docket Nos. 50-369, 50-370 Response to Request for Additional Information - Topical Report DPC-NE 1005P, Revision 0, Nuclear Design Methodology Using CASMO-4/
SIMULATE-3 MOX(Proprietary), (TAC Nos. MB2578, MB2579, MB2726 and MB2729)
Reference:
- 1) NRC Letter dated July 29, 2002, Request for Additional Information Re: Topical Report DPC-NE-1005P, Revision 0, Nuclear Design Methodology Using CASMO-4 / SIMULATE-3 MOX
- 2) Duke Letter dated September 12, 2002, Response to Request for Additional Information Re: Topical Report DPC-NE-1005P, Revision 0, Nuclear Design Methodology Using CASMO-4 / SIMULA TE-3 MOX (PROPRIETARY)
Duke's initial response to Reference 1 was provided in Reference 2. However, this response was incomplete because some of the information was proprietary to Electricite de France (EDF) and Duke did not have an affidavit from EDF supporting the withholding of the proprietary information. The missing information consisted of References 19 and 20 from Duke Topical Report DPC-NE-1005P, Nuclear Design Methodology Using CASMO-4/SIMULA TE-3 MOX (requested in Question 20 of Reference 1) and the response to Question 8 from Reference 1.
Enclosed are two copies each of References 19 and 20 from Duke Topical Report DPC-NE 1005P. In addition, supplementary information to that contained in Reference 20 is enclosed in order to provide the NRC staff with operating data from Saint Laurent B 1 operating cycles (campaigns) eight, nine, and ten, which were benchmarked in the topical report. Attachment 1 is the proprietary response to Question 8 from Reference 1 and Attachment 2 is the redacted version of the response with all of the EDF proprietary information deleted.
This submittal contains information that is proprietary to EDF. In accordance with 10 CFR 2.790, Duke requests that this information be withheld from public disclosure. An affidavit from EDF is included that attests to the proprietary nature of the information.
PROPRIETARY Material Attached
U.S. Nuclear Regulatory Commission November 12, 2002 Page 2 In a related matter, Duke has requested that the NRC staff provide written confirmation of the planned schedule for the review of the subject topical report. To date, Duke has not received this information. This schedule is still needed in order for Duke to plan for the use of the methodology in the topical report for future fuel cycle designs.
In addition, Question 22 of Reference 1 pertained to the provision of documentation and software for the CASMO-4 and SIMULATE-3 MOX computer codes. As noted in the initial Duke response (Reference 2), Duke would like to work with the NRC staff to identify an arrangement that will enable the NRC staff to perform its review, while at the same time addressing Duke and Studsvik Scandpower, Inc., concerns associated with the NRC staff request.
Duke is still awaiting the NRC staff's response to Duke's proposal on this issue.
Inquiries on this matter should be directed to G. A. Copp at (704) 373-5620.
Very truly yours, K.

U AFFIDAVIT OF CATHERINE GAUJACQ My name is Ms Catherine Gaujacq. I am President of Electricit6 de France International North America de France.
2 Mr. Michel Ponticq who has the responsibility for reviewing information sought to be withheld from public disclosure in connection with nuclear power plant licensing has asked me to sign in his lieu et place.
3 Thus I am authorized on the part of EDF to apply for this withholding.
- 4.
I am making this affidavit in conformance with the provisions of 10 CFR 2.790 of the regulations of the Nuclear Regulatory Commission (NRC) and in conjunction with Duke Energy Corporation's application for withholding, which accompanies this affidavit.
- 5.
I have knowledge of the criteria used by EDF in designating information as proprietary or confidential.
- 6.
Pursuant to the provisions of paragraph (b)(4) of 10CFR 2.790, the following is furnished for consideration by the NRC in determining whether the information sought to be withheld from public disclosure should be withheld.
(i)
The information sought to be withheld from public disclosure is owned by EDF and has been held in confidence by EDF and its consultants.
(ii)
The information is of a type that would customarily be held in confidence by EDF.
The information consists of operating data for reactor cores with a mixture of mixed oxide and low enriched uranium fuel that were developed at significant cost to EDF and which provide a competitive advantage to EDF.
(iii)
The information is to be transmitted to the NRC in confidence and under the provisions of 10CFR 2.790, and is to be received in confidence by the NRC.
(iv)
The information sought to be protected is not available in public to the best of our knowledge and belief (v)
The proprietary information sought to be withheld is that which is marked in the proprietary version of Duke Energy's response to the Request for Additional Information from the Nuclear Regulatory Commission dated July 29, 2002 concerning Duke topical report DPC-NE-1005, Nuclear Design Methodology Using CASMO-4/SIMULATE-3 MOX. The proprietary information sought to be withheld from public disclosure has substantial commercial value to EDF because the information (a) Is not available to other parties and would require substantial cost to develop independently, (b) Has been sought by other parties in return for monetary payment, 12- (
U (Continued)
Catherine Gaujacq (c) Consists of reactor operating data, which is not readily available to others and therefore has value to EDF,
- 7.
Public disclosure of this information is likely to cause harm to EDF because it would allow other competitors in the nuclear industry to benefit from the results of an extensive reactor monitoring and measurement program without requiring commensurate expense or allowing EDF to recoup a portion of its expenditures or benefit from the sale of the information.
Catherine Gaujacq, being duly sworn, states that she is the person who subscribed her name to the foregoing statement, and that all the matters and facts set forth within are true and correct to the best of her knowledge.

- 8. In the first paragraph of section 3.2.5, the last sentence states that the fission chambers are very similar. What are the differences between them?
Response
The statement in Section 3.2.5 is made based on the similarity of those detector characteristics which are important to the nuclear performance of the device. The St.
Laurent detectors are slightly smaller than the McGuire/Catawba detectors since the instrument thimbles in St Laurent are smaller. Table 2 below summarizes the important parameters of the incore instrument in each reactor.
