Gentlemen:

SUBJECT: INSPECTION NO. 50-346/86-024

Enclosed is the report of the team inspection conducted by Mr. R. C. Wilson and

other NRC representatives on August 4 to 7, 1986 at the Davis-Besse Nuclear

Power Station, Unit No.1 of activities authorized by NRC License No. NPF-3.

This inspection was a continuation of the inspection begun on February 24 to

28, 1986 and described in Inspection Report No. 50-346/86-024 dated June 13,

1986. These inspections reviewed your implementation of a program as required

by 10 CFR 50.49 for establishing and maintaining the qualification of electric

equipment within the scope of 10 CFR 50.49. Within these areas, the inspection

consisted of examinations of selected procedures and records, interviews with

personnel, and observations by the inspectors. In February the inspectors

determined that the Davis-Besse equipment qualification program was not suffi-

ciently far along to determine its compliance with 10 CFR 50.49, and the initial

inspection report listed numerous unresolved items.

Based on the August continuation of the inspection we have determined that you

l

have implemented a program to meet the requirements of 10 CFR 50.49. Three

deficiencies in your program implementation, summarized in Appendix A, are

classified as Potential Enforcement / Unresolved Items and will be referred to

the NRC Region III office for further action. These deficiencies involve

failure to demonstrate qualification of the high range radiation monitor cable,

Amphenol penetration assemblies, and two ASCO solenoid valves. Four additional

,

concerns are classified as Open Items, and a future NRC inspection will review

'

your actions concerning them. Details of all the deficiencies and concerns are

j discussed in the enclosed inspection report.

The Amphenol and ASCO Potential Enforcement / Unresolved items were corrected by

August 7. In a November 17, 1986 telephone conversation you advised that the

other Potential Enforcement / Unresolved Item was corrected, and that virtually

all of the Open Items were completed. Your corrective actions regarding any

remaining concerns and the completion of other planned efforts should not be

delayed pending a future NRC inspection or further action by the NRC Region

III office.

We are available to discuss any questions you have concerning this inspection.

Sircerely,

Potential Enforcement / Unresolved Items

As a result of the special equipment qualification inspection on February 24

to 28 and August 4 to 7, 1986, the following items have been referred to NRC

Region III as Potential Enforcement / Unresolved Items (section references are

to detailed portions of the inspection report).

1. Contrary to paragraph (j) of 10 CFR 50.49, at the time of the inspection

Toledo Edison Cenpany's (TED) files did not adequately document qualifi-

cation of Rockbestos coaxial cable used in the high range radiation monitor

because the ability to reet specified performance requirements during

accident conditions was not shown. Specifically, the ability to satisfy

footnote 9 to Table 3 of Reg. Guide 1.97 was not demonstrated for low

radiation levels at high containment temperatures. (Section 4.D.(1),

Item 50-346/86-024-01)

2. Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and section 5.2.5 of

the D0R Guidelines, at the time of the inspection TED's files did not

adequately document qualification of Amphenol penetration assembifes

because the ability to meet plant performance requirements during

accident conditions was not shown. Specifically, electrical performance

during accident testing was not measured and shown to be acceptable.

(Section 4.D.(2), Item 50-346/86-024-02)

3. Contrary to paragraphs (f) and (k) of 10 CFR 50.49 and section 5.2.6 of

the D0R Guidelines, at the time of the inspection TED's installation of

ASCO solenoid valves, plant ID SVICS11B1 and 2, was not shown to be

!

qualified. Specifically, the use of qualified cable entrance seals was

not demonstrated as required by the type test report for the steam

service conditions (235 F) documented in the files. (Section 4.D.(3),
