- 1. SCOPE This document describes the seismic qualification tests conducted March 20-23, 1978 on correntes panel, MPL No. H13-P618, Div 2 RHR B&C Relay Vertical Board. The panel is of vertical design, 72.00 inches wide x 36.00 inches deep x 90 inches high. The panel contains essential components including switches, relays, trip units, an inverter, field contact input isolators and a high level output isolator. Test results are applicable to BWR/6 panels of similar con-
- figuration, and with similar essential devices. Tests were conducted per GE specifications 225A5766 and 22A4320 according to the test requirements specified in Engineering Work Authorization (EWA) number EAD05 . Tests were performed to both IEEE344-1971 (225A5766) and IEE344-1975 (22A4320) requirements.

Panel was mounted en Seismic Table per Seismic Qualification Procedure 22A4320, Paragraph 5.1. For the performance of Longitudinal testing, the panel wu rotated 900 and remounted per the aforementioned procedure.
- 6. INSTRUMENTATION l 6.1 ACCELEROMETER MOUNTING Initid accelerometer mountings are as shown in Figure 6-1.. During the lateral dual axis test, accelerometer No. 3 was removed in order that it might be used to asasure floor motion (vertical). For longitudinal testing acceleroatter No. 8
- was added to the right rear of the panel (as shown in Figure 6-1) approximately 4 ft from the bottom. This was done to measure high accelerations noted at the

Single axis and dual axis tests were performed.
7.1 SINGLE AIIS TESTS , 7.1.1 A very slow sine sweep from 2 Hz to 35 Hz at a G level of Ig (P-P). This test was performed in the vertical, lateral (front to back) and longitudinal axes.

DRF# H13-42 l j
Data from this test are recorded on an oscillegraph recorder and are used to deter-eine transmissibilities and natural frequencies.
7.1.2 A 30-second (minimum) 1.Og (p-p) sine dwell at natural frequencies deter-mined in Paragraph 7.1.1.
I 7.2 DUAL AIIS TESTS 7 2.1 Dual axis OBE and SSE Random Response Spectrum Tests for both vertical /
lateral and vertical / longitudinal. These random response tests were conducted with .
input signals in phase and 1800 out of phase. The Dual Axis Response Spectrum Tests were conducted per GE Specification TP 510.0221, Rev. A. Table response spectra were plotted for each dual axis random test.
- 8. TEST RESULTS 8.1 GENERAL All of the equipment under test performed without any malfunction. No apparent I
damage occurred to the panel nor to the remainder of equipment mounted on the panel.
Roof panels were loose but bolts were tightened following the first test and no further vibrations were noted. Power supply 16hC5261 was not available for the test. Its physical location is directly below accelerometer No. 3, which recorded a maximum of 2.lg's (P-P) in the longitudinal direction, 3.Sa's (P-P) in the lateral direction and lg (P-P) in the vertical direction. This instrument was previously fragC.ity tested at g levels of 7 or better (Reference Report #58059, Wyle Lal The Topaz inverter.s (164C5243P008) were in the cabinet but were not " hot" tested.
They, too, are loca ted at the bottom of the panel below accelerometer No. 3 These inverters were previously fragility tested at levels greater than 7g's (Reference Report No. 30592, Viking Labs).
8.2 LATERAL (FRONT TO BACE) SINE SWEEP 1-33 Hz,13 (P-P)
A is level input to the table with a slow sine sweep from 2 to 33 Hz revealed a resonance at 25 Hz (Table 8-1). . Accelerometer No. 7 had the highest transmissi-
- bility (7.8) and acceterometers Nos. 4 and 2 with an amplification factor of 5 8
ORM H13-42 were the second highest. The trip units are in the area of au slerometers 4 and 5; the highest trip unit was operational during tests and performed without malfunction.
The isolators (accelerometer No. 6) sustained lateral g forces of 4.3 P-P at 25 Hz and operated without malfunction.
- 8.3 LATERAL DWELL TEST (25 Hz, 13 (P-P)
Dwell tests in the lateral direction were run at 23 Hz (Ig) for 15 see and at l 25 Hz for e 40 sec. Results were similar to those obtained in the sine sweep test; accelerometer No. 7 was slightly higher in g level, however.
8.4 LONGITUDINAL SINE SWEEP 1-33 Hz, 1g (P-P)
Accelerometer No. 8 was added to the rear of the panel for these tests, due to the vibrations noted at the open end of the panel. (No instruments are located in this area) (Figure 6-1).
i I
A major resonance occurred at 19 Hz and accelerometer No. 8 showed 11g's (P-P) force. Accelerometer No. 6 (at isolator) showed a force of Sg (P-P) . The isolators operated nomally, however. No anomalies were noted during this test (Table 8-2).
8.5 LONGITUDINAL DWELL 19 Hz, 1g (P-P) e 45 see All equipment operated normally before, during and following the test.
8.6 VERTICAL SINE SWEEP 1-33 Hz 13 (P-P)
A minor resonance was noted at 33 Hz (Table 8-3). All equipment performed nor-mally before, during, and following the test.
I Vertical Dwell = 33 Hz e 50 sec. See results on Table 8-3 All instruments operated nomally before, during and following the test.

DRF# H13-42 8.7 DUAL AXIS RESPONSE SPECTRA Figures 8-1 through 8-8 are dual axis response spectra for OBE's and SSE in the Vertical / Lateral and Vertical / Longitudinal directions. Tests were perforned with ir.put signals in phase and 1800 out of phase. The Plant Response Spectrum used in these tests is far more severe than the Required Response Spectrum for Cofrentes.
All' equipment under test operated normally beforc, during and following each test.
No damage was noted on any of the other equipment.
- 9. CONCLUSION H13-P616 is capable of withstanding seismic forces greater than those specified in the Required Response Spectrum for Cofrentes, as indicated by both single axis and dual axis testing.
Results obtained indicate seismic qualification of this panel for the Cofrentes Site.
