Dear Mr. Eisenhut:

Re:

St. Lucie Unit 1

Docket No. 50-335 Turbine Rotors Florida Power 8 Light Company (FP8L) has reviewed your letter dated February 25, 1980 requesting, in accordance with 10 CFR 50.54(f), information relative to disc integrity in Westinghouse 1800 RPM low pressure nuclear turbines.

Specifically, your request attached a set of six site-specific questions and a

second set of eight generic questions.

Your letter also urged that the generic questions be addressed through an owners group.

As requested, responses to the generic questions were coordinated through a task force, of which FP8L is a member, which is chaired by Mr. Wayne Stiede of Commonwealth Edison.

It is our understanding that Westinghouse will submit responses to the generic questions directly to your office and that you are in agreement with this method of submittal.

As a result of discussions at an industry Task Force meeting in Tampa, Florida on March 12-13,

1980, we understand that a site-specific information submittal date of March 19, 1980 is acceptable to the NRC.

Such information is provided in Attachment 3.

St. Lucie is currently shutdown for refueling, and inspections of the LP rotor discs will be performed during the outage.

Please note that our response contains information considered to be proprietary by the Westinghouse Electric Corporation.

In conformance with 10 CFR 2.790, as

amended, we are also forwarding an APPLICATION FOR WITHHOLDING INFORMATION FROM PUBLIC DISCLOSURE (Attachment 1) and an Affidavit (Attachment 2).

The affidavit sets forth the basis on which the proprietary information contained in Attachment 3 may be withheld from public disclosure by the Commission.

(1) I am Hanager, Customer Order Engineering in the Steam Turbine Generator Technical Operations Division of Westinghouse Electric Corporation and as such, I have been specifically delegated the function of reviewing the proprietary information sought to be withheld from public disclosure in connection with nuclear power

~ plant licensing, and am authorized to apply for its withholding on behalf of the Westinghouse Power Generation Divisions.

(2) I am making this Affidavit in'conformance with the provisions of 10 CFR Section 2.790 of the Commission's,regulations and in conjunction with the Westinghouse application for.withholding accompanying this Affidavit-(3) I have personal knowledge of the criteria and procedur es utilized by Westinghouse Power Generation Divisions in designating informa-tion as a trade secret, privileged or as confidential commercial or financial information-(4)

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

(i) 'he information sought to be withheld from public disclosure is owned and has been held in confidence by Westinghouse.

(ii)

The information is of a type customarily held in 'confidence by Westinghouse and not customarily disclosed to the pub-lic.

Westinghouse 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 confi-dence.

The application of that system and the substance of that system constitutes Westinghouse policy and provides the rational basis required.

Under that system, information -is held in confidence if it

'falls in one or more of several

types, the release of which might result in the loss of an existing or potential com-petitive advantage, as follows:

(a)

The information reveals the -distinguishing aspects of a process (or component, structure, tool, method, etc.)

where prevention of its use by any of Westinghouse's competitors without license from Westinghouse consti-tutes a competitive economic advantage over. other companies.

{b) It consists of supporting data, including test data, relative to a process (or component, structure,

tool, method, etc.),. the application of which data secures a

competitive economic advantage, e.g.,

by optimization or improved marketability.

-(c) Its use by.a competitor would reduce his expenditure of resources or improve his competitive position in the

design, manufacture, shipment, installation, assurance of quality, or licensing a similar product (d) It reveals cost or pr ice information, production capac-ities, budget levels, or commercial strategies of West-inghouse, its customers or suppliers-(e) It reveals aspects of past,

present, or future Westing-house or customer funded development plans and programs of potential commercial value to Westinghouse.

(f) It contains patentable ideas, for which patent protec<<

tion may be desirable.

(g) It is not the property of Westinghouse, but must be treated as "proprietary by Westinghouse according to agreements with the owner.

(h)

Public disclosure of this information would allow un-fair and untruthful judgments on the performance and reliability of Westinghouse equipment components and improper comparison.with similar components made by

.-competitors-There are sound p'olicy reasons behind the Westinghouse, system which include the following:

(a)

The use of such information by Westinghouse gives Hest-inghouse a competitive advantage over its competitors.

'It is, therefore, withheld from disclosure to protect the Westinghouse competitive position.

(b) It is information which is marketable in many ways.

The extent.to which such information is available to competitors diminishes the Westinghouse ability to sell products and services. involving the use of the information.

(c)

Use by our competitor would put Westinghouse at a com-petitive disadvantage by reducing his expenditure of resources at our expense.

(d)

Each component of proprietary information pertinent to a particular competitive advantage is potentially as valuable as the total competitive advantage.

If com-petitors acquire components of proprietary information, any one component may be the key to the entire puzzle, thereby depriving Westinghouse of a competitive advantage.

(e)

Unrestricted disclosure would jeopardize the position of prominence of Westinghouse in the world market, and thereby give a market advantage to the competition in

~

those countries-

(f)

The Westinghouse capacity to invest corporate'assets in r esearch and development depends, upon the success in obtaining and maintaining a competitive advantage.

(iii)

The.information is b'eing transmitted to the Commissi'on,in confidence

and, under 'the pr'ovisions of 10 CFR Sec-tion 2.790, it is to be received in confidence by the Commission.

r (iv)

The information is not available in public sources'to the best of our knowledge and belief-(v)

The proprietary information sought to be withheld in this

, submittal is that which is appropriately mar ked in Appen-dix A to letter from R. E. Uhzig to

Eisenhut, dated March 19, 1980

,, concerning infor-mation in response to NRC request for information of February 25, 1980, relative to low pressure turbine disc integrity.

The information enables Westinghouse to:

(a)

Develop test inputs and procedures to satisfactorily verify the design of Westinghouse supplied equipment.

(b)

Assist its customers to obtain licenses.

Further, the information has substantial commercial value as follows.

(a)

Westinghouse can sell the use of this information to customers.

(b)

Westinghouse uses the information to verify the design of equipment which is sold-to customer s.

(c)

Westinghouse can sell"services based upon the ex'per-fence gained and the test.equipment and methods developed.

Public disclosure of this information is likely to cause substantial harm to the competitive position of Westinghouse because it would enhance the ability of competitors to

design, manufacture, verify, and sell, electrical equipment for commercial turbine-generators without commensurate expenses-Also, public disclosure of the information would enable others having the same or similar equipment to use the information to meet NRC requirements for licensing documentation without purchasing the right to use the information.

The development of the equipment described in part by the information is the result of many years of development by Westinghouse and the expenditure of a considerable sum of money.

This could only be duplicated by a competitor if he were to invest similar sums of money and provided he had the appro-'riate talent available and could somehow obtain the requi-site experience.

Further the deponent sayeth not.

ATTACHMENT 3

RESPONSE

TO NRC REQUEST FOR INFORMATION RELATED TO TURBINE DISCS SITE-SPEC IF IC GENERAL QUESTIONS I.

LP Turbine design and o crating data:

A. '~bi The Florida Power 8 Light Company, St. Lucie ¹1 unit consists of one tandem compound four flow, three casings, condensing, 1800 RPM turbine utilizing 44 in. last row blades in each low pressure element.

The low pressure element is designated as a Building Block (28l.

B.

Hours of o eration for each LP Turbine:

Both LP rotors installed in the Unit 1 turbine had operated a total of approximately 24,120 hours0.00139 days <br />0.0333 hours <br />1.984127e-4 weeks <br />4.566e-5 months <br /> as of March 15, 1980 when the unit was taken off-line for refueling.

Based on current Westinghouse i nspection criter ia, an inspection of the Unit 1

LP rotors would be indicated based on the 5-year operating criterion rather than the

P ll CI tl

postulated crack size criterion.

Unit 1 will not achieve 5 years of operation on the LP rotors until mid-1982.

However, in recognition of current NRC concerns as well as the potential commercial penalties associated with a disc failure, FPL will inspect the LP rotors at St. Lucie Unit 1 during the current outage.

fP8L will provide the results of this inspection to the NRC when the results become available.

C.

Number of turbine tri s and overs eeds:

Based on the limited review predicated by the required response time, our records i ndicate that Unit 1 has undergone approximately 9

overspeed trips and 62 turbine trips from power operation.

The 9 overspeed trips were the result of required testing of the overspeed trip device, and the 62 turbine trips reported are based on records of reactor trips.

As reactor trips at low power levels will not necessarily involve a turbi ne trip, this number (62) is also subject to revision.

We will continue our review of existing records and advise you of any changes to this response resulting from this review.

Keyway temperatures are listed in Section G of the Appendix A data for each disc.

This is the calculated temperature two inches from the exhaust face of the disc at the bore during full load operation with all moisture separator reheaters functioning.

Note that this value, as the major input into the calculation of crack growth rate, is only valid for calculational purposes for those discs which in normal operation run "wet"-

Westinghouse data indicates that no bore or keyway cracking has occurred in discs that run "dry".

Calculated ke wa crack size for turbine o eratin time in I.B.

above:

See item I.D.4.

The calculated crack size is a function of the estimated maximum crack growth rate, based on empirical data, and the equi pment operating hours.

This value, based on current NRC criteria, 'is given in Section G of Appendix A.

Recent Westinghouse research and analyses have yielded conclusions that differ significantly from those values based on current NRC criteria.

A summation of results pursuant to these conclusions, which also address items I.D. 6, 7, and 8, is appended (Appendix B) ~

Our response is based, where applicable, on these conc'fusions.

Critical crack size:

See item I.D.5. above.

9.

Calculated bore and ke wa stress at o eratin desi n overs eed:

The bore tangential stresses at design speed and design overspeed are presented in Section E of Appendix A.

The values presented include the stresses due to shrink fitting and centrifugal force loads only.

Additional analyses to include thermal stresses and pressure stresses are being performed but are presently not available.

.Keyway stresses vary from zero to a high fraction of yield strength.

10. Calculated K

data:

The fracture toughness, K1C, of each disc is calculated from the Charpy V-notch and tensile data.

These values, presented in Sections B. 11.

and C.9. of Appendix A are calculated at either h

the Upper Shelf Temperature or room temperature, whichever yields the lower result.

ll. Minimum yield stren th s ecifi ed for each di sc:

The minimum yield strength for each disc is presented in Section B.l of Appendix A.

II.

Results of com leted inservice ins ections:

Relative to the disc bore and keyway areas of the Unit 1

LP rotors, only visual inspections have been performed.

No significant abnormalities

U.

U

have been noted.

III.

Provide the nominal water chemistr conditions for each LP turbine and describe any condenser i.nleaka es or other si nificant chan es in secondary water chemistr to this oint in its o eratin life.

Discuss the occurrence of cracks in an iven turbine as related to histor of secondar water chemistr in the unit:

Unit 1 does not have the capability to perform chemical analyses at the LP turbine.

However, FP&L, in conjunction with Westinghouse, is conducting testing on both Turkey Point Units 3 and 4 to determine several parameters (pH, conductivity, and others) of the steam entering the LP turbines.

We can provide, at your request, the results of this testing when the results beccme available.

Nominal water chemi stry philosophy and a record of condenser inleakages

are, however, included in our response as Appendix C.

We have been unable to identify to date any correlation between turbine disc cracking of any type and secondary chemistry.

In point of fact recent industry research indicates that disc cracking may be independent of secondary water chemistry, that is cracking may occur even in a pure steam envi rorment.

IV.

If our lant has not been ins ected describe our ro osed schedule and a

roach to ensure that turbine cracki n does not exi st in our turbine:

It is presently impossible to ensure that cracking does not exist in the Unit 1 LP rotor discs as cracki ng has been empirically proven to exist
