'On0 Prospect Hill Road Windsor, Connecticut 06095 H POWER SYSTEMS Docket No.: STN 50-470F April 26,1983 LD-83-035 Mr. Darrell G. Eisenhut, Director Division of Licensing U.S. Nuclear Regulatory Commission Washington, D.C. 20555

Subject:

Fuel Design Evaluation Summary for CESSAR-F

Reference:

Letter LD-83-017, A. E. Scherer to D. G. Eisenhut, dated February 28, 1983

Dear Mr. Eisenhut:

The reference letter transmitted proposed modifications to Section 4.2 of CESSAR-F to reflect the performance of some additional fuel design analyses.

Coabustion Engineering (C-E) has performed the stress, strain, and strain fatigue analyses for the System 80" fuel assembly, fuel rod, burnable poison rod and CEA, except for the seismic and LOCA analysis. In addition, the assembly lift-off and the CEA axial growth analyses were performed, and show acceptable results.

In response to questions from the NRC staff reviewer, the attached summary was

~

prepared to augment the documentation on the CESSAR-F docket. "CESSAR Fuel and CEA Design Evaluation Sunnary Report" presents analytical results of the analysis ctted above. Twenty-five (25) copies of the proprietary version and fifteen (15) copies of the non-proprietary version are enclosed.

Due to the proprietary nature of the material enclosed, we request that it be withheld from public disclosure in accordance with the provisions of 10 CFR 2.790 and that this material be safeguarded. The reasons for the proprietary classification of this report are delineated in the enclosed affidavit.

If I can be of any further assistance in this matter, please contact me or Mr.

G. A. Davis of my staff at (203) 688-1911, extension 2903.

Very truly yours, 3- N4 COMBUSTION ENGINEERING, INC. 1/l5

I, A. E. Scherer, depose and say1that I am .the Director, Nuclear ' Licensing,

of; Combustion. Engineering, Inc., duly authorized to make this affidavit, and have reviewed or caused to have reviewed the information which is identified as proprietary and: referenced in the paragraph immediately below. I am submitting

~

=

this affidavit in conformance with the provisions of 10 CFR 2.790 of the

, Commission's regulations for withholding this information.

[

The-information-for which proprietary-treatment is sought is contained in

- the following-document:

Enclosure 1-P to LD-83-035 .CESSAR ~ Fuel and CEA Design Evaluation Si maary Report, ' April 1983.

j - This: document has been appropriately designated as proprietary.

I have personal knowledge of the criteria and procedures utilized by -

l- - Combustion Engineering in designating .information as a trade secret, privileged

-or as' confidential commercial or financial information.

e Pursuant to the provisions of paragraph (b) (4) of Section 2.790 of- the F

l~ Commission's regulations, the following is furnished for consideration by the p

[ Commission in' determining whether the information sought to be withheld from t.

public disclosure, included in the above referenced document, should be withheld, t

U i

1. The information sought to be withheld from public disclosure are analytical results of the System 80" fuel and CEA design calculations,which is owned and has been. held in confidence by Combustion Engineering.

2. The information consists of test data or other similar data concerning a process, method or component, the application of which results in a

~

substantial competitive advantage to Combustion Engineering.

3. The information is of a type customarily held in confidence by Combustion Engineering and not customarily disclosed to the public. Combustien

- Engineering has a rational basis- for determining the types of information customarily held in confidence by it and, in that connection, utilizes a system to determine ^when and whether to hold certain types of information in confidence. 'The details of the aforementioned system were provided to the Nuclear Regulatory Commission via letter DP-537' from F.M. Stern to Frank Schroeder dated December 2, 1974. This system,was applied in determining that the subject . document he.ein are proprietary.

4. The information is being transmitted to the Commission in confidence under the provisions of 10 CFR 2.790 with the understanding that it is to be received in confidence by the Commission.

5. The information, to the best of my knowledge and belief, is not available in public sources, and any disclosure to third parties has been made i

. pursuant to regulatory provisions or proprietary agreements which provide for maintenance of the information in confidence.

6. Public disclosure of the information is likely tc cause substantial

narm to the competitive position of Combustion Engineering because

a. A similar product is manufactured and sold by major pressurized water reactor competitors of Combustion Engineering.

-- ..- w ._. - - _ _ . , - - - . - . . _

m

b. Development of this information by C-E required thousands of manhours of effort and hundreds of thousands of dollars. To the best of my

~

knowledgeand belief a competitor would have to undergo similar expense in generating _ equivalent information.

c. -In order to acquire such information, a competitor would also

~ require considerable time and inconvenience related to the performance of fuel system design calculations for the System 80" fuel and CEA design,

d. The information required significant ef fort .and expense to obtain the licensing approvals necessary for application of the information.

Avoidance of this expense would . decrease a competitor's cost in applying the information and marketing the product to which the information is applicable,

e. The information consists of analytical results of the System 80" fuel and CEA design calculations, the application of which provides a competitive economic advantage. The availability of such information to competitors would endble them to modify their product to better compete with Combustion Engineering, take marketing or other actions to improve their product's position or impair the position of Combustion Engineering's product, and avoid developing similar data and analyses in support of their processes, methods or apparatus,

f. In pricing Combustion Engineering's products and services, significant research, development, engineering, analytical, manufacturing, licensing, quality assurance and other costs and expenses must be included.

The ability of Combustion Engineering's competitors to utilize such information without similar expenditure of resources may enable them to sell at prices rcflecting significantly lower costs.

(-

g. Use of the information by competitors in the international marketplace would increase their ability to market nuclear steam supply systems by reducing the costs associated with their technology development. In

, addition, disclosure would have an adverse economic impact on Combustion Engineering's potential for obtaining or maintaining foreign licensees.

Further the deponent sayeth not.
