' Inservice-inspec', ion of steam generator tubing is essential in order to maintain surveil-lance of the concitions of the tubes in the event that there>is evidence of.

mechanical damage or progressive degradation due to design, manufacturing-errors, or inservice conditions that lead to corrosion; Inservice-inspection i

of steam generator tubing also provides a means of characterizing the nature and cause of any tube degradation so that corrective measures can be taken.

The plant is expected'to be operated in a manner such that the secondary I

coolant will be maintained within those chemistry limits found to result in:

j negligible corros. ion of the steam generator tubes.

If the secondary. coolant chemistry is not maintained within these limits, localized corrosion may :

i likely result in stress corrosion cracking.

The extent of cracking during

)

plant operation would be limited by the limitation of. steam generator tube I

leakage between the primary coolant system and~the secondary coolant system i

(primary-to-secondary leakage = 0.5 gpa per steam generator)., Cracks having -

a primary-to-secondary leakage less than this limit during operation will have l

an adequate margin of safety to withstand the loads-imposed during' normal j

operation and by postulated accidents. Operating plants have' demonstrated i

that primary-to-secondary leakage of 0.5 gpa per. steam generator can readily:

j be detected by radiation monitors of. steam generator blowdown.- Leakage in~

.J excess of this limit will require plant shutdown and'an unscheduled inspection, j

during which the leaking tubes will be located and plugged.

)

/

1 i

Wastage-type defects are unlikely with proper chemistry treatment of the secondary coolant.

However, even if a defect should develop.in service, it j

will be found during scheduled inservice steam generator tube examinations.

Plugging will be required for all tubes with' imperfections exceeding the i

plugging limit of 40% of the tubs nominal wall thickness.. Steam generator

]

tube inspections of operating plants have' demonstrated the capability to j

j reliably detect degradation that has penetrated 20% of,the original-tube wall 1

thickness.

i 1

i Whenever the results of any steam generator tubing inservice inspection-l t

fall into Category C-3, these results will be promptly reported to the 1

Cnemission pursuant to Specification 6.9.1 prior the resumption of. plant operation. Such cases will be considered by the Commission on a case-by-case

{

basis and may result in a requirement for analysis, laboratory examinations,.

REACTOR COOLANT SYSTEM BASES STEAM GENERATORS (Continued) based on a modification of Regulatory Guide 1.83, Revision 1. Inservice inspaction of steam generator tubing is essential in order to maintain surveillance of the conditions of the tubes in the event that there is evidence of mechanical damage or progressive degradation due to design, tr.anufacturing errors, or Inservice conditions that lead to corrosion. Inservice inspection of steam generator tubing also provides a means of characterizing the nature and cause of any tube degradation so that corrective measures i

can be taken.

The plant is expected to be operated in a manner such that the secondary coolant will be maintained within those chemistry limits found to result in negligible corrosion of the steam generator tubes. If the secondary coolant chemistry is not maintained within these limits, localized corrosion may likely result in stress corrosion cracking.

The extent of cracking during plant operation would be limited by the limitation of steam generator tube leakage between the primary coolant system and the secondary coolant system (primary-to-secondary leakage - 0.5 gpm per steam generator). Cracks having a l

primary-to-secondary leakage less than this limit during operation will have an adequate margin of safety to withstand the loeds inposed during normal operation and by postulated accidents. Operating plants have demonstrated that primary to-secondary leakage of 0.5 gpm per steam generator can readily be detected by radiation monitors of steam generator blowdown. Leakage in excess of this limit will require plant shutdown and an unschedulei inspection, during which the leaking tubes will be located and plugged or repaired.

l Wastage-type defects are unlikely with proper chemistry treatment of the secondary coolant. However, even if a defect should develop in service, it will be found during scheduled inservice steam generator tube examinations. Plugging or sleeving will be required for all tubes with imperfections exceeding the plugging or repair limit as defined in Surveillance Requirement 4.4.4.4.

Defective tubes may be repaired by sleeving in accordance with LENS Report CEN 605 P, "Waterford 3 Steam Generator Tube Repair Using Leak Tight Sleeves," Revision 00 P dated December, 1392: WES Report WCAD-13698, " Laser Welded Sleeves For 3/4 Inch Diameter Tube Feedring-Typ and Westinghouse Preheater Steam Generators," Revision 1, dated May, 1993: or BWNS Report 51-1223750 00, *BWNS Kinetic Sleeve Design for CE SGs with 0.048" Wall Tubes," Revision 00, dated June 29, 1993.

Steam generator tube inspections of operating plants have demonstrated the capability to i

reliably detect degradation that has penetrated 20% of the original tube wall thickness. Sleeved tubes will be included in the periodic tube inspections for the inservice inspection program..

Whenever the results of any steam generator tubing inservice inspection fall into Category C 3, these results will be promptly reported to the Comission pursuant to Specification 6.9.1 prior the resumption of plant operation. Such cases will be considered by the Comission on a case-by case basis and may result in a requirement for j

analysis, laboratory examinations, tests, additional eddy-current inspection, and revision of the Technical Specifications, if necessary.

l This document has been appropriately designated 4 *roprietary.

I have personal knowledge of the criteria and -procedures utilize.1 by Combustion Engineering in designating information as a

j J

j trade secret, privileged or as confidential commercial of financial j

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 Commission in determining ' whethe:-

the 1

}

I informr. tion 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, which is owned an. has been held in confidence by combustion r

Engineering, is the design, manufacture, installation, and testing of the steam generator tube welded sleeve for' repairing

]

degraded tubes.

2.

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

Combustion Engineering has a rational basis for determining the types of information customarily held in i

confidence by it and, in that connection, utilizes.a system-to i

determine when and whether to hold certain-types of information in confidence.

The details of the aforementioned system were l

provided to the Nuclear Regulatory Commission v'ia 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 is 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 infornation, 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 proprietary-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 because:

i a.

A similar product is manufactured and sold -by major l

pressurized water reactor competitors:. of.

Combustion I

i Engineering.

{

b.

Development of this information by C-E required. thousands of manhours and'. millions'of dollars.-.ToJthe_best'of my

-l knowledge and belief, a competitor'would have to undergo j

similar expense in generating equivalent"information.

c.

In order to acquire such'information, a competitor would l

i also require. considerable time and inconvenience to' develop l

I a similar method for steam generator. tube repair using leak l

tight sleeves for-degraded tubes.

d.

The information required significant effort and expense to.

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' I

applicable.

e.-

The-information consists of-the methodology used to repair.

steam generator tubes using. leak. tight sleeves,. the application of which provides a -' competitive economic:

advantage.

The : availability oft =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 Eltgineering's product,

-J and avoid developing similar data and analyses in support i

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

-l 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.

l AFFIDAVIT OF JAMES H. TAYLOR A.

My name is James H. Taylor.

I am Manager of Licensing Services for B&W Nuclear Technologies (BWNT), and as such I am authorized to execute this Affidavit.

B.

I am familiar with the criteria applied by BWNT to determine whether certain information of BWNT is proprietary and I am familiar with the procedures established within BWNT to ensure the proper application of these criteria.

l C.

In determining whether a BWNT document is to be classified as proprietary information, an initial determination is made by the Unit Manager, who is responsible for originating the document, as to whether it falls within the criteria set forth in Paragraph D hereof.

If the information falls within any one of these criteria, it is classified as proprietary by the originating Unit Manager.

This initial determination is reviewed by the cognizant Section Manager.

If the document is designated as proprietary, it is reviewed again by Licensing personnel and other management within BWNT as designated by the Manager of Licensing Services to assure that the regulatory requirements of 10 CFR Section 2.790 are met.

D.

The following information is provided to demonstrate that the provisions of 10 CFR Section 2.790 of the Commission's regulations have been considered:

(i)

The information has been held in confidence by BWNT.

l Copies of the document are clearly identified as proprietary.

In addition, whenever BWNT transmits the 4

o 1

AFFIDAVIT OF JAMES H. TAYLOR (Cont'd.)

information to a customer, customer's agent, potential customer or regulatory agency, the transmittal requests the recipient to hold the information as proprietary.

Also, in order to strictly limit any potential or actual customer's use of proprietary information,_the following provision is included in all proposals submitted by BWNT, and an applicable version of the proprietary provision is included in all of BWNT's contracts:

" Purchaser may retain Company's proposal for use in connection with any contract resulting therefrom, and, for that purpose, make such copies thereof as may be necessary.

Any proprietary information concerning Company's or its Supplier's products or manufacturing processes which is so designated by l

Company or its Suppliers and disclosed to Purchaser I

incident to the performance of such contract shall l

l remain the property of Company or its Suppliers and is disclosed in confidence, and Purchaser shall not publish or otherwise disclose it to others without the written approval of Company, and no rights, implied or otherwise, are granted to produce or have produced any products or to practice or cause to be practiced any manufacturing processes covered thereby.

Notwithstanding the above, Purchaser may provide the NRC or any other regulatory agency with any such proprietary information as the NRC or such other-agency may require; provided, however, that Purchaser shall first give company written notice of such proposed disclosure and Company shall have the right to amend such proprietary information so as to make it non-proprietary.

In the event that Company cannot amend such proprietary information, Purchaser l

l 2

AFFIDAVIT OF JAMES H. TAYLOR (Cont'd.)

shall, prior to disclosing such information, use its best efforts to obtain a commitment from NRC or such other agency to have such information withheld from public inspection.

I Company shall be given the right to participate in l

pursuit of such confidential treatment."

I l

(ii)

The following criteria are customarily applied by BWNT in a rational decision process to determine whether the information should be classified as proprietary.

Information may be classified as proprietary if one or more of the following criteria'are met:

a.
