Louisiana Power & Light Waterford SES Unit No. 3 C.E. P.O. 9403341-9270 (W) IED W8000 Seismic Qualification Review Team Audit Item NSSS 6 NCI SORT No. NSSS ICE-5A Resistor Card Reviewer: R. W. Macek Audit Date: Sept. 1, 1982

Reference:

Westinghouse Electric Corp. Seismic Test Report - WCAP 8828 Seismic Operability Demonstration Testing of the Westinghouse IED 7300 Series Process Instrumentation Bistables Gentlemen:

The subject audit concluded with one action for Westinghouse Industry Electronics Division (WIED) as follows:

" Verify by means of test data that operability of resistor input card was demonstrated during the test".

Mr. Macek noted that WCAP 8828 included the NCI card in its equipment listing, Table 2-1, demonstrating the cards inclusion in the test. He also noted there was no direct mention of, or data to show, the cards operability during the test.

Westinghouse stated that the evidence of NCI operability could be provided but it would be in the nature of raw data, i.e. block diagram sketches, schematic sketches, copies of strip chart recordings and explanations showing linkage bet-ween WCAP 8828, the NCI card, signal names, sketches and recordings.

h__

Combustion Engineering Page September 10, 1982 The followinng is a list of attachments to this letter which will serve to demonstrate operability of the NCI card:

Attachment A. Block diagram of circuitry in Card Frame #1 Attachment B. Schematic of Card Frame #1 Wiring Attachment C. Strip Chart recording of NCI outputs Attachment A defines, in block diagram form, the circuitry of card frame #1.

Attachment B defines the hardware and wiring which implements the block diagram.

Attachment C shows strip chart recordings of signals described in Attachments A

& B.

The relationship of NCI card output, signal name and recorder / pen number are as follows:

NCI Output Signal Recorder No. Pen No.

TD/411 A A TLL 2 3 TD/411E TC 2 4 TD/412A TAVG 2 5*

TD/411B OPSP 2 6 TD/411C OTSP 2 7 In Attachment C, the signal on Pen #2 was purposely changed in order to vary the input to bistables to demonstrate that they change state. The signals on recorder pens 3,4,5 & 6 are not functionally affected by the signal on Pen #2, and therefore, remain at a steady state value. The signal on Pen #7 is func-tionally affected and, therefore, moves as expected. The Attachment C recording was run during the seismic test and showed no anomalies.

Therefore, the operability of the NCI card is demonstrated.

If I can be of any further service, please advise.

Very truly yours,

//W" ! /

ATTACilMENT 2

~

The instrument u'ncertainty analysis has been completed. Included in this analysis is the 5%

indication uncertai.ity (due to seismic) associated with the SIGMA Indicator Model No.1151. The results show that the plant design is sufficiently .

conservative to accommodate the combined effects of the instrument channel uncertainties, including the 5% uncertainty due to seismic, and insure safe operation of the plant.
