5.0 TEST DESCRIPTION 5.1, The test items were mounted in the vibration fixture, one above the other, CPC 2 on the top.
Each box was fastened to the fixture using four 1/4 - 20 x 5/8 binding head screws backed with flat washers.
The backs of the test i tems were tied together using two 1/16 inch thick stainless steel plates (See Drawing No. 510359).
5.2 Electrical inputs were supplied to the calculators and DC voltage outputs were monitored at selected test points using a digital voltmeter.
Output voltages were also monitored using a recording oscillograph in order that rapid changes in voltage such as spikes could be detected.
Page 2 of 10
5.3 A continuity tester was placed between terminals 49 and 63 of CPC 2 in order to detect relay contact closure.
The relays'ontacts were opened and closed during seismic testing in order to assure proper operation..
5.4 The calculators were subjected to five operating basis earth-quakes (OBE) and one safe-shutdown earthquake (SSE) with the excitation applied along the YZ axis (See Fig. 1).
In order to retest the calculators with )he excitation along the XZ axis, the-test fixture was rotated 90 on the shake table.
The cal-culators were resubjected to five operating-basis earthquakes and one safe-shutdown earthquake.

6.3 The test voltages were continuously monitored during each shake using a recording oscillograph.
Examination of the recordings revealed no spikes or other anomalies due to testing.
6.4 7.0 The relay contacts of CPC 2 were caused to open and close once during each shake.
The relays continued to operate properly throughout the test.
COMMENTS 7.1 7.2 8.0 During the first shake (OBE 1, Y Z Axis), the voltage at Terminal 30 of CPC 2 jumped 21 mi,llivolts from the base reading.
The increase in voltage,
- however, was not due to seismic testing.
It was found that switching on power to
~
the recording oscillograph had caused the peak detector module to jump to a higher state.
The reset button was de-pressed causing all readings to return to their base values.
Seismic testing was continued without further incidence.
~ The Calculators, CPC1 and
- CPC2, having met the.requirements for qualification of Seismic-Category 1 instrumentation, are new considered seismically qualified for use in nuclear gen-erating stations.
