J/N 17110 S aject: Okonite Tape Splices I told t%em that the purpose of the call was twofold First- I had received word that there was concern from the NRC, that there were some problems with the Wyle Report No. 17947-01. f problems do exist, this may be a 10CFP part 21 situation and I needed to know this.

Second- There appears to be come concern over the use of this report to show qualification of the subject splicos at LP&L. I would like to know what the problems are.

on the first issue, they agreed ". hat they had uncovered no errors in the r-~;rt and thus there was not a part 21 O problem.

On the second issue, the following r ablems exist:

1. The test was done originally is swer and control circuits and Chuck doesn't think the res, ts can be extrapolated to instrument circuits.

2. The low side of the splices won't show leakage and therefore it's not a valid test.

3. Leakage current was zero, thus raising a flag on the integrity and accuracy of the measu.ing circuit.

4. LP&L did not produce a specific test on splices in an instrument circuit or completely address which transmitters are affected and the accuracy needed.

Discussion:

I explained that three sets of two splices each, a high side splice and a low side splice were tested. It was agread that most leakage would occur from the high side splice, assuming both splices were good. It was agreed that the high side splice (137.5 VDC) enveloped an instrument circuit of O 30 VDC, typical. The low side was representative of a low side DC. Sinco three high side splices were in the test and 9207310130 920518 PDR ADOCK 0b000340 0 PDR

071315

, only one high side splice is required for qualification, These splicos constitute a valid extrapolation for an instrument circuit. (Chuck disagreed with Mark and myself on this point, invoking problem i 1, in-spite of the evidence to the contrary) .

The leakage current of zero is not itself in question, rather Mark vant's supporting evidence such as IR's during the test and/or a through explanation of Wyle's QA on the circuit and the accuracy or threshold of the circuit. He would like to know how much leakage may be in the circuit.

LP&L needs thic so that they can resolve problem #4.

In future ?.ests Wyle should consider actual Transmitter circuits, and confirmation of circuit accuracy with leakage -

current and IR measurements during the test.

On a separate issue, Harold thanked me for some information of equipment sealing which I had sent him a few months ago.

Action: J. Henley : Pleasa resove test circuit accuracy proble=s and meet with LP&L on 11-29-89 during there audit of Wyle.
