SUBJECT:

Calvert Cliffs Nuclear Power Plant Unit Nos. 1 & 2; Docket Nos. 50-317 & 50-318 Review of Realistic Large Break LOCA Analysis - Supplemental Information

REFERENCE:

(a)

Letter from J. J. Stanley (CCNPP) to Document Control Desk (NRC),

dated December 1, 2011, Review of Realistic Large Break LOCA Analysis In Reference (a) we requested a review of an updated realistic large break loss-of-coolant accident (LOCA) analysis to comply with a license condition. An AREVA evaluation (both proprietary and non-proprietary versions) was attached to the request. Further review of that evaluation has discovered several minor errors, including the failure to properly redact certain proprietary information in the non-proprietary report. Please remove the existing non-proprietary version of this report from public access.

Please replace the proprietary and non-proprietary versions of the evaluation provided in Reference (a) with the attached versions. Attachment (1) contains the proprietary version of the evaluation. Since this evaluation contains information that is proprietary to AREVA, it is accompanied by an affidavit signed by AREVA, the owner of the information (Attachment 2). The affidavit sets forth the basis on which the information may be withheld from public disclosure by the Commission, and address, with specificity, the considerations listed in 10 CFR 2.390(a)(4). Accordingly, it is requested that the information that is proprietary to AREVA be withheld from public disclosure. The non-proprietary version of the evaluation (Attachment 3) is included for public disclosure.

We apologize for any inconvenience this may have caused. Should you have questions regarding this matter, please contact Mr. Douglas E. Lauver at (410) 495-5219.

Very ly yours James J. Stanley Manager-Engineering JJS/PSF/bjd

1.

My name is Gayle F. Elliott. I am Manager, Product Licensing, for AREVA NP Inc. (AREVA NP) and as such I am authorized to execute this Affidavit.

2.

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

3.

I am familiar with the AREVA NP information contained in the report ANP-3043(P), Revision 001, entitled "Calvert Cliffs RLBLOCA Summary Report," dated December 2011 and referred to herein as "Document." Information contained in this Document has been classified by AREVA NP as proprietary in accordance with the policies established by AREVA NP 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 AREVA NP 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 this Document be withheld from public disclosure. The request for withholding of proprietary information is made in accordance with 10 CFR 2.390. The information for which withholding from disclosure is

requested qualifies under 10 CFR 2.390(a)(4) "Trade secret and commercial or financial information."

6.

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

(a)

The information reveals details of AREVA NP'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 AREVA NP.

(d)

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

(e)

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

The information in the Document is considered proprietary for the reasons set forth in paragraphs 6(b) and 6(c) above.

7.

In accordance with AREVA NP's policies governing the protection and control of information, proprietary information contained in this Document have been made available, on a limited basis, to others outside AREVA NP only as required and under suitable agreement providing for nondisclosure and limited use of the information.

8.

AREVA NP policy requires that proprietary information be kept in a secured file or area and distributed on a need-to-know basis.

9.

The foregoing statements are true and correct to the best of my knowledge, information, and belief.
