The licensee's program for conducting huh ,aot; ilal [overvoitige] tests f on cables in the 4160 V safety-related distribution system was reviewed by ;

the NRC inspectors. The high potential test consist of applying a DC i overvoltage to each conductor in the cables for a specified tim i i In Section 17.1 of the FSAR the licensee stated that the QA program, for I i construction is designed to conform to Regulatory Guide (RG) 1.30 "Quality 1 Assurance Requirements for the Installation Inspection, and Testing of l Instrumentation and Electric Equipment." RG 1.30 which endorses ANSI . :

N45.2.4-1972 (same title as RG 1.30 also designated IEEE Std. 336-1971), ,

.

'

calls for the conducting of overpotential test, RG 1.30 does not !

specifically call for inspectors to witness the overpotential tes !

Therefore, the licensee must decide whether or not those persons ;

i conducting the overpotential test have sufficient independence from those i

! responsible for installing the cables to conform to the requirements of [

.

GpCs Quality Asse ance Program in order to determine whether or not inspectors are required to monitor the test.

]

I Details for carrying out the high potential test are specified in several !

l industry standards. However, the licensee did not commit to using any !

} particular standar Procedure 25733-C "High Potential Testing Cable" Rev. 4 specifies, for the 4160 Volt system cables, that 36KV DC be applied -

to each conductor for five consecutive minutes. The procedure also states l

<

that, if the leakage current increases with time, extend the test period :

to 15 minutes. The tests were conducted after the cables were installed !

I and before they were energize !

+

The scope of the inspection was to review the applicable procedures and to i j review three data sheets for tests completed on cables selected at random,- I

!

!

Plant Vogtle Field Procedure. ED-T-07 "Cable 1 Insta11stion", Rev.12, t covers the performance of high potential test on cables. Had the test i been carried out by the Electrical Field Office, which is ?esponsible for !

,

construction ED-T-07 would have been used. However, the conducting of i J

the high potential test was delegated to the Start-up group (Site l l

Operations). The Start-up group used their own procedure, 25733-C, High

,

potential Testing Cable" to carry out the test. Procedure E0-T-07 calls,

for the Electrical Quality Control (QC) Inspection Supervisor to be notified prior to start of testing for Class IE cables. The procedure

, specifies the notification as a "Q.C. HOLD POINT". Procedure 25733-C

,

!

specifies, if work is safety-related, notify Q.C. prior to start of wor ,

Review of test sheets for safety-related cables 2BA0313EA, 2BA0306E and .

2AA0213EA indicated that the test was completed using the specified  !

voltage, time duration and acceptance criteria of 100 micro-Amperes ,

leakage current. However, review of the data sheets for the three selected cables revealed that Quality Control did not sign-off the hold points as required by the procedure. In addition, the persons completing the data sheets checked-off non-safety-related when in f act the cables  :

were safety-related [two cables, one had no check].

l The licensee investigated this matter after the NRC inspectors brought it to the attention of GpC management. As a result of this investigation, it l was revealed that an engineer from the Nuclear Operations group noted on l November 24, 1987, that Procedure 25733-C was not being followed with i respect to the notification of The engineer informed his supervisor :

-

of the failure to follow procedure. However, apparently the matter was l not investigated, since an Operations Deficiency Report was not written at  :

that time. The NRC was further informed that QC was . involved in a test ,

i conducted on November 30, 1987, and all subsequent high potential tes '

i" As a result of this inspection finding, an Operations Deficiency Report '

has been generated after the inspection. According to licensee personnel, '

l the "QC HOLD POINT" was by passed during the testing of 37 cable '

) Since several questions raised by the NRC Inspectors required some '

research by the licensee, all the facts surrounding this matter could not

be determined during the time period of the inspection. Questions asked of ,

, the licensee include the following:  !

1 How many cables (total) require the high potential t:st? l

" How many high potential test were carried out according to all provisions of the procedure, including the notification of QC7 ,

4 .

How did it happen that in at least two cases non-safety related was i d

checked off when in fact the cable was safety-related? In how many

instances did this occur?

J Was the test carried out according to the recommendations of an industry standard?

j In summary, the licensee chose to make notification of QC prior to l conducting each high potential test a "QC HOLD POINT." One may conclude

'

this was important to his Quality Assurance program. Since the hold point ,

was by-passed in 37 cases, NR0 requirements in the area of procedures apparently were violated. However, all circumstances surrounding this
