!' -Q.1 Please state your names.

.A.1 Richard M. Bucci,_Edwin J. Pagan and' Peter M._Yandow.

Q.2 _Mr.-Bucci and Mr. Pagan, are your; addresses, occupa-tions,. employers,-educational backgrounds and professional work-experiences describec elsewhere in-the record of this. proceed-l ing?-

l h 'A.2' (RMB, EJP) Yes,..the relevant information.is.provided-in'" Applicants' Testimony of' Richard M. Bucci-and Edwin J.,

Pagan in~ Response to Eddleman Contention 9D (Instrument Ca-l bles)."

~Q.3 Mr. Yandow, are your address, occupation, employer, f

l educational background and professional work experience de-scribed elsewhere in the record of this proceeding?

A.3 (PMY) Yes, the relevant information is provided in

" Applicants' Testimony of Robert W. Prunty and Peter M. Yandow in Response to Eddleman Contention 9 (Environmental Qualifica-

-tion of Electrical Equipment)."

Q.4 Maat is the purpose of this testimony?

A.4 (RMB, EJP, PMY) The purpose of this testimony is to respond to Eddleman Contention 9F, which states:

The effects of radiation on lubricants and seals have not been adequately L addressed in the' environmental quali-fication program.

l f Q.5 How is your testimony organized?

I l A.5 (RMB, EJP, PMY) First, we provide background infor-L

mation on lubricants and seals used in safety-related l  ;-

L l  ? ,

m

f'. 3

.6 electrical equipment for the SHNPP. Second, we discuss how Ebasco assures.that the effects of radiation on lubricants and seals used in safety-related electrical equipment which it sup-plies for SHNPP are adequately addressed. Then we describe

.CP&L's program to asrure that the effects of, radiation on lu-bricants used in non-Ebasco supplied safety-related electrical equipment are adequately addressed.

Q.6 What is a lubricant?

A.6 (PMY) A lubricant is an oily or greasy substance which provides a near-frictionless film on two or more surfaces which roll, rub or rotate against each other.

Q.7 What kinds of safety-related electrical equipment at the SHNPP use lubricants?

A.7 (PMY) Motors, valve operators and pumps are three examples of safety-related electrical equipment which use lu-l bricants.

Q.8 What is a " seal," as addressed in Eddleman Contention 9F?

l A8 (PMY) A seal is a device -- static or dynamic; me-tallic or organic -- that prevents foreign substances from en-tering equipment or retains a required substance within the equipment.

Q.9 What kinds of safety-related electrical equipment at SHNPP have seals?

l A.9 (PMY) Transmitters, valve operators, pumps and re-sistance temperature detectors are examples of safety-related electrical equipment which have seals.

Q.10 What safety-related electrical equipment does Ebasco

,. - supply for the SENPP?

L' A.10 (RMB, EJP) .Ebasco supplies all balance-of-plant L

i '(" BOP") safety-related electrical equipment for SHNPP, i.o.,

, equipment which is not part of the Nuclear S, team Supply System

("NSSS"). .This equipment is listed in Table 3.11.0-2 of the

! ;Shearon Harris Nuclear Power Plant Final Safety Analysis Report l

("FSAR") (Applicants' Exhibit .

).

l Q.11 How are lubricants and seals in BOP safety-related electrical equipment environmentally qualified for radiation effects?

l I A.11 (RMB, EJP) All BOP safety-related electrical equip-ment for SHNPP which is located in a harsh environment is qual-ified by test. Equipment which normally contains lubricants or seals is tested with those components as part of the equip-ment. ,

Qualification testing consists of accelerated thermal aging, irradiation, and a design basis accident simulation (if applicable). During the irradiation portion of the testing program, electrical equipment is irradiated as a whole, including any seals or lubricants. The qualification test re-ports identify _the radiation dose to which the equipment is ex-posed. In every case, the radiation exposure of the electrical equipment during testing exceeds the maximum total integrated radiation dose to which the equipment could be exposed over its qualified life. The required radiation exposure is based on 8

r 6

normal operating conditions, design basis accident conditions (1f applicable), and post-accident conditions (if applicable).

(Not all safety-related electrical equipment is located in areas of the plant which will be subjected to accident and/or post-accident conditions.) ,

Q.12 How does Ebasco assure that the lubricants and seals tested are the same as the lubricants and seals supplied or recommended by the vendor?

A.12 (RMB, EJP) For BOP equipment, Ebasco reviews the vendor test reports to identify organic components of the test-ed equipment, including lubricants and seals. Ebasco compares the lubricants and seals identified in the test report to the lubricants and seals supplied or recommended by the vendor in order to verify that they are the same.

Q.13 What steps are taken if lubricants or seals are not identified in the test report, or if there is a discrepancy be-tween the lubricants or seals identified in the test report and those recommended by the vendor?

A.13 (RMB, EJP) If there is a discrepancy, ambiguity or omission concerning the icentification of a lubricant or seal which was tested, supplied or recommended by the vendor, Ebasco then attempts to resolve the open item by requesting additional information from the vendor. If the vendor cannot demonstrate that the lubricant or seal supplied or recommended in the same as that tested, corrective action is required to qualify the different components. Any corrective actions must be documented in the environmental qualification package.

Q.14 Who supplies the NSSS safety-related electrical equipment for SHNPP?

A.14 (PMY) Westinghouse supplies this equipment, which is listed in FSAR Table 3.11.0-1. (Applicants' Exhibit __).

Q.15 Are lubricants and seals used in N,SSS' safety-related electrical equipment?

A.15 (PMY) Yes, some NSSS safety-related electrical equi.pment use lubricants and seals. Either metallic seals, which are not degraded by the environmental conditions for which electrical equipment must be qualified, or organic seals, which are qualified as part of the equipment tested, are used.

Q.16 How are lubricants in NSSS nafety-related electrical equipment environmentally qualified for radiation exposure?

A.16 (PMY) Westinghouse does not identify the specific lubricants used during testing. Rather, Westinghouse recom-mends a general type of lubricant and provides the specifica-tions the lubricant must meet to assure operability of the equipment.

Therefore, CP&L has contracted for and received a lu-brication study performed for the SHNPP by the Mobil 011 Com-pany, a loacing lubricant vendor. The purpose of the study was to identify, for each piece of electrical equipment which re-quires lubrication, the specific brands of lubricants which can be used with that equipment. CP&L currently is reviewing the adequacy of the study.

In the study, the results of radiation stability O

b testing is provided. Radiation stability testing included standard performance tests which were conducted both before and during irradiation to measure the effects of radiation. For each lubricant to be used in a piece of NSSS electrical equip-ment, the radiation dose received during lubricant testing will be compared to the total integrated done which the equipment must be qualified to receive at SHNPP. The radiation dono re-ceived during testing must be highor than the done for which the equipment is required to be qualified. In addition, the performance of the lubricant during testing will be reviewed to I

verify that the equipment manufacturer's lubricant performanco specifications have boon mot.

Q.17 How will information rogarding the qualification of lubricanta for radiation exposure be documented?

A.17 (PMY) CP&L will develop an environmental qualifica-tion package which will document the tonta described in the lu-bricant study, as well as the analynos which apply tho test re-nuits to opacific electrical equipment at SHNPP, Q.18 In conclusion, have Applicants adoquately addrooned the effects of radiation on lubricanto and naals in their onvi-ronmental qualification program?

A.A0 (RMB, EJP, PMY) Yes. For lubricants and monin in Ebanco nupplied BOP nafety-related electrical equipment, the naals and lubricants are exposed to radiation during qualifica-tion tents as components of the cloctrical equipment tostod.

Ebanco verifies that the sonin and lubricants supplied with O

.D .

safety-related electrical equipment are the same as those test-ed. Seals in NSSS safety-related electrical equipment are ei-ther metallic seals, which need not.be qualified, or, organic seals,;which are qualified as"part of the equipment tested.

CP&L has contracted for a lubricant study to qualify lubricanta 4 to be used in NSSS safety-relat'ed equipment and elsewhere-in the SENPP, including qualification.for radiation exposure.
