'AEP:NRC:0775AM Donald C. Cook Nuclear Plant Unit No. 2 Docket No. 50-316 License No. DPR-74 ENVIRONMENTAL QUALIFICATION TEST PROGRAM CHANGES CONCERNING THE SAFETY INJECTION PUMP MOTOR U.S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC 20555 Attn: A. B. Davis

Dear Mr. Davis:

The purpose of this letter is to notify you of certain changes we have found necessary to make in the scope and schedule of Tasks 1 and 2 of our safety injection pump motor environmental qualification program. This program was described in our letter AEP:NRC:0775AL, dated March 3, 1987. (A copy of this letter is attached for your convenience.)

As described in our March 3, 1987 letter, Task 1 of the testing program consists of performing an evaluation, based on a search of existing literature, to predict the effects of radiation on the insulating varnish used by the noncertified motor-repair shop. Radiation effects on the interaction between this varnish and the original stator winding insulation will also be evaluated. This task was originally scheduled to begin in March 1987. However, due to delays in obtaining a detailed material listing of the make-up of the safety injection pump motor from the manufacturer (Westinghouse), this task has been rescheduled to begin in June 1987.

With regard to Task 2 of the testing program, we had originally planned to perform radiation testing of a sample pump motor stator winding to be fabricated by Westinghouse. Westinghouse has subsequently informed us that many of the materials originally used in the manufacture of the pump motor stator are no longer commercially available. As a result, our current plan is to perform radiation testing of the entire safety injection pump motor in question unless the Task 1 evaluation conclusively shows that the motor in its present condition will be unaffected by an accident environment.

O. Box 16631 Columbus. Ohio 43216-6631

'ear Mr. Kraszewski; As you requested during our meeting at Battelle on February 20, 1987, Battelle is preparing a proposal for the evaluation of materials used in a Westinghouse 400 horsepower motor for Class IE service. The proposed prolect will involve two parallel efforts:

Search of technical literature to locate information and data, on the varnish and paint used to treat the stator of the Westinghouse motor.

~ Materials irradiation to determine the possible interaction of the original motor coating materials with the newly added varnish and paint.

Enclosed with this letter you will find an outline of the anticipated effort for the above two tasks. and an estimated schedule for the completion of the efforts.

If you have any questions concerning the proposal being prepared, please contact me at (614)424-7386, or Larry Lowry of the Nuclear Technology Section at (614)879-5338, Very truly yours.

TEST PLAN OUTLINE FOR FOUR HUNDRED HP MOTOR MATERIALS QUALIFICATION TASK 1 INFORMATION SEARCH A- Printed information base search 1- Contact motor manufacturer for materials and process speci f ications.

2- Search printed engineering indexes to a- Determine key words used to index information about Class IE equipment. large horse power motors, and coating materials used in large motors and nuclear environments.

b- Identify journals etc. publishing information on large horse power motors used in nuclear environments.

c- Identify authors p'ublishing on nuclear coatings, equipment used in nuclear environments, and large horse power motors.

3- Search annual indexes of printed lournals publisning information on large motors used in nuclear environments and coatings used in nuclear environments.

4- Obtain copies of significant articles. reports, etc.

5- Contact authors lcompanies) for additional information and original data that might be used to qualify coatings and coating combinations for Class IE service.

8- Computerized data base information search 1- Define search strategy on the basis of key words and vocabulary of the technology as determined from the search of printed data bases.

2- Perform interactive data base search and obtain on-line listing of "hit" titles. This search will be limited to 1976 to the present

l p 3-, Review articles titles and order abstracts of significant articles for off-line printing. Order off-line printing of review-type articles. The ordered material to be delivered by express maiL t

4- Review abstracts and order complete copies of significant articles, reports. etc.

5- Review bibliographies oi review-type articles and order significant articies. reports, etc.

6- Contact authors icompanies) of very significant information to learn if more recent reports are available and whether not raw data can be made available for qualification of materials for Class IE service.

7- Obtain more recent reports and available data.

C- Analyze information and prepare a report and recommendations.

E MATERIALS QUALIFICATION TEST The following materials qualification tests will be performed with appropriate quality control procedures in effect to insure the accuracy and validity of the data generated.

A- Contact motor manufacturer for materials and process specifications.

B- Radiation monitoring qualification, C- Map gamma field of radiation source.

D- Obtain or fabricate test sample.

E- Prepare test sample:

a- application of coatings.

b- attachment of electrical contacts.

c- attachment of thermocouples, F- Prepare test sample for irradiation:

a- attachment of dosimeters.

b- enclose in contamination shield.

G- Preliminary measurements.

H- Insert sample in irradiation tube.

I- Irradiate sample and:

a- temperature measurements.

b- electrical measurements.

c- remove selecte'd dosimeters at appropriate times.

J- Remove sample from irradiation tube.

K- Process dosimeters.

L- Process and analyze data.

M- Prepare report and recommendations.
