Duke Power Company McGuire Nuclear Station Docket Nos. 50-369 and 50-370 Catawba Nuclear Station Docket Nos. 50-413 and 50-414 Topical Report DPC-3004-P, " Mass and Energy Release and Containment Response Methodology" l
Enclosed for your review is Duke Power Company's Topical Report DPC-NE-3004-P,
" Mass and Energy Release and Containment Response Methodology." This report i
describes Duke's methodology for simulating the mass and energy release from high-energy line breaks, and the resulting containment response for the Catawba and McGuire Nuclear Stations. The methodology described in this report was used in analyses which will support replacement of the steam generators at McGuire and Catawba Nuclear Stations. Duke Power is requesting review and approval of this submittal by September 30,1995, in order to support the replacement schedule for McGuire Unit 1.
In accordance with 10CFR 2.790, Duke Power Company requests that this report be considered proprietary. Information supporting this request is included in the attached affidavit. A non-proprietary version of DPC-NE-3004 will be submitted following receipt of the Safety Evaluation Report.

4 AFFIDAVIT OF M S TUCKMAN 1.
- I am Senior Vice President, Nuclear Generation Department, Duke Power
)
Company (" Duke"), and as such have the responsibility of reviewing the i
proprietary information sought to be withheld from public disclosure in
)
connection with nuclear plant licensing, and am authorized to apply for its i
withholding on behalfof Duke.
l 2.
I am making this ailidavit in conformance with the provisions of 10 CFR 2.790 of the regulations of the Nuclear Regulatory Commission ("NRC") and in conjunction with Duke's application for withholding which accompanies this r
aflidavit.
3.
I have knowledge of the criteria used by Duke in designating information as
- proprietary or confidential.
l 4.
Pursuant to the provisions of paragraph (b)(4) of 10 CFR 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 Duke and has been held in confidence by Duke and its consultants.
(ii)
The information is of a type that would customarily be held in confidence f
by Duke. The information consists of analysis methodology details, analysis results, supporting data, and aspects of development programs, relative to a method of analysis that provides a competitive advantage to -
l Duke.
(iii)
The information was transmitted to the NRC in confidence and under the provisions of 10 CFR 2.790, it 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 in this submittal is that which is marked in the proprietary version of the report DPC-NE-3004,-
" Mass and Energy Release and Containment Response Methodology" and supporting documentation, and omitted from the non-proprietary versions.

AFFIDAVIT OF M S TUCKMAN (Page 2)
This information enables Duke to:
(a)
Simulate the mass and energy release rates from loss-of-coolant accidents and steam line break accidents in pressurizer water i
reactors of the Westinghouse design.
(b)
Simulate the response of an ice condenser dry containment design to a high-energy line break inside containment.
(vi)
The proprietary information sought to be withheld from public disclosure has substantial commercH value to Duke.
(a)
It allows Duke to reduce vendor and consultant expenses -
associated with supporting the operation and licensing of nuclear.
power plants.
-l (b)
Duke intends to sell the information to nuclear utilities, vendors, and consultants for the purpose of supporting the operation and licensing of nuclear power plants.
(c)
The subject information could only be duplicated by competitors at similar expense to that incurred by Duke.
p 5.
Public disclosure of this information is likely to cause harm to Duke because it would allow competitors in the nuclear industry to benefit from the results of a significant development program without requiring a commensurate expense or allowing Duke to recoup a portion ofits expenditures or benefit from the sale of
'I
^
the information.
