ARIZONA PUBLIC SERVICE COMPANY (APS)

PVNGS UNIT 1 I.  : Description of Deficiency After hot functional testing of Unit 1, a visual inspection of the Reactor Coolant Pump 1-RCE-P01-1A and associated piping was performed. It was revealed that the thermal liner, for the 14" safety injection nozzle installed in line SI-A207-BCCA-14" had broken loose and was missing. Further investigation determined that the liner was wedged between the outer shell and the flow baffle of the reactor vessel. The liner was retrieved from the reactor-vessel by Combustior Engineering (C-E) and shipped to C-E's Chattanooga facility for inspection and problem resolution. The results of this inspection and related analyses are contained in t '

the attached C-E report entitled " Report on Palo Verde Unit 1 ,

Safety Injection Nozzle Thermal Liner", (Document No. CEN-264(V)-P).

II. Analysis of Safety Implications The analys'is of safety implications is provided in Sections 3.0,

. " Inspections'and Examinations", and 4.0, " Problem Definition", of the " Report on Palo Verde Unit 1 Safety Injection Nozzle Thermal Liner", attached.

III. Cerrective Action C-E recommended that the three (3) remaining thermal liners for Unit 1 be removed, and the explansion grooves blended into the nozzle wall area. The thermal liners, four (4) per unit, for Units 2 and 3, will also be removed, and the explansion grocves will be blended to preclude stress risers in the safety injection nozzles.

Bechtel is implementing the required correctfre actions, via the following design change packages, before fuel load for the respective units.

ISM-RC-102 2SM-RC-102 3CM-RC-102 In addition, SAR Change Notice No. 1131 will be issued prior to Unit 1 fuel load to identify the deletion of the thermal liners from the safety injection nozzles. This SAR change will reflect the deviation from the standard System 80 design as described in CESSAR Section 5.4.3.

AFFIDAVIT PURSUANT TO:10 CFR 2.790' Combustion Engineering, Inc.  :)

, I, A.' E. LSch'erer',jdeposeJand .say that _I am the Director, Nuclear Licensing, of Combustion Engineering,~ Inc.,- duly authorized to make this affidavit, and have sreviewed or caused to have ' reviewed-the information' which is identified as proprietary and referenced in the. paragraph immediately below. I am submitting

'thisJaffidavit in conformance with the provisions of-10 CFR 2.790 of the Commission's regulations and in conjunction with the application of Arizona Public Service for withholding this information.

The'information for which proprietary treatment is sought is contained in the following document:

CEN-264(V)-P, " Report on .Palo Verde Unit 1 Safety Injection Nozzle Thermal

' Liner".

.This document has been appropriately designated as proprietary.

LI have personal knowledge of the criteria and procedures utilized by

' Combustion Engineering in designating information as a trade secret, privileged

, or_ as confidential commercial or financial information..

' Pursuant to the provisions of paragraph-(b)'(4) of Section 2.790 of the Commission's regulations, the following is furnished for consideration by the LCommission in determining whether the information sought to be withheld from public disclosure, included in the above ' referenced document, should be withheld.

1. :The information sought to be withheld from public disclosure is the methodology related to _the' determination' of usage factors and-design features Lof reactor coolant, system components, 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 informati_on-is of a type customarily held in confidence by Combustion Engineering and not customarily disclosed to the'public. Combustion 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 herein are proprietary.

4. - The information' is being transmitted to the Commission in confidence under the prov'isions' of 10 CFR 2.790 with the understanding that i_t 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

-pursuant to regulatory provisions or pronrietary agreements which provide for

. maintenance of the information in confidence.

6. -Public ~ disclosure of the information is likely to cause substantial harm to the competitive position of Combustion Engineering becausa:

[1*

F i

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

b. Development of this information by C-E required thousands of manhours of effort and tens of thousands of dollars. To the best of my knowledge and 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 development of methodology to determine usaga factors and design features of reactor coolant system components.

d._ The information required significant effort 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 methodology related to the determination of usage factors and design features of reactor coolant system components, the application of which provides a competitive economic advantage. :The availability of such information to competitors would enable 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 processas, 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

_ _ _ _ _ _ _ _ - _ _ _ _ _ _ _ _ _ _ _ _ _ _ . i

without similar expenditure of resources may enable them to sell at prices

! reflecting 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.
