. SYN 0PSIS Seismic Testing of Panels H22-P0178, H22-P018 and H22-P005 was completed on October 25, 1978. All three panels were mounted on the table and tested simultaneously. Essential instruments were pressurized usir.g de-fontzed water and the pressurizing calibration units attached to each panel. Monitoring of the pressurized instruments during the test was accomplished by visual observation of pressure gages and voltage readings on meters which were -

representative of the pressures. Pressure integrity was maintained throughout the testing and no anomalies were noted. Amplifications as high as 14 were noted on the instruments at the panel resonant frequencies. The normal dual axis tests performed far exceeded the requirements for the Cofrentes site. The additional dual axis tests (MSIV-SSE) performed showed that at panel resonances, the g levels felt at the panels were greater than those established by the BWR 6 Standard Plant Response Spectrum.

Tests were conducted per GE Specification 22A4320 and according to the instructions contained in EWA EAD-05-19 Rev. O. TP510.0221 was used as a guide in the perfomance of dual axis testing. Two types of tests were perfomed as follows:

7.1 A very slow sine sweep from 3H z to 60Hz at a g level of 0.5g (p-p) to u termine transmissibilities and natural frequencies of the panels.

These tests were run in all three orthogonal axes.

f 1

! a. 100 seconds of Operating Base Earthquake (OBE) in both lateral /

vertical and longitudinal / vertical directions with input signals l

8.1 GENERAL Pressure integrity was maintained in all three panels throughout the testing. Small variances in the pressure readings were attributed to temperature changes in the Seismic Test Facility which has no air conditioning. All panels responded to all dual axis tests and no damage was observed on the equipment. The highest amplifications at resonant frequencies were in the lateral direction (fr,ont to back).

8.2 LATERAL SINE SWEEP (front to back)

A slow sine sweep 0.5g (p-p) from 3 to 35 Hz was applied to the panel.

Upon reaching 35 Hz, the test was continued manually for each frequency up to 60 Hz. The results of this test are tabulated in Table 1 for all three panels. The following is a brief summary of the results.

8.2.1 H22-P017B (30" panel)

This panel had a major resonance at 24.5 Hz. Transmissibilities at this frequency show an amplification of % 9.7 at the lower i row of transmitters and % 14.3 at the upper row of transmitters.

A secondary minor resonance was noted at 60 Hz-8.2.2 H22-P005 (48" panel)

Resonances on this panel occurred at 15.5 Hz and 45 H z . The resonance at 15.5 Hz was the more severe of the two.

Amplification of 8 was noted at the lower row of transmitters and 14 at the upper row of transmitters.

8.2.3 H22-P018 (72" panel)

A major resonance occurred at 15.5 Hz. Amplifications measured at this frequency were % 3.6 at the lower row of transmitters, 8 at the upper row of transmitters and % 18 at the top of the panel. (No instruments are located near this latter area.) A l

second minor resonance was noted at 24.5 Hz and a third resonance at 48 Hz. Transmissibility plots of the 48 Hz resonance show amplifications of % 9 at the lower row of transmitter and % 12 at the upper row of transmitters.

8. ,7 SPECIAL SSE TEST The SSE and OBE Plant Response Spectra described in the preceeding paragraphs represent the maximum machine capability at the GE San Jose Seismic Test Facility. These resoonse spectra are far more severe than the Required Response Spectra for Cofrentes and most of the other BWR-6 facilities. Since a few plants, such as TVA, have a still higher requirement, a special Plant Response Spectrum (MSIV-SSE) was also applied to the three panels. This Floor Response Spectrum is initiated at %3 Hz instead of %) Hz and thereby requires less displacement and can reach higher g values from 10 Hz to 45 Hz. The resulting curves (with points on curve decreased bv a factor of ,7-) enveloo the BWR 6 Required Response Spectrum in the frequency domain where the three panels showed resonances.

Tests were conducted In-phase and out of phase both in the Lateral /

Vertical exes and the Longitudinal / Vertical axes. Figures 9, 10, 11 and 12 are plots of the MSIV SSEs performed on the three panels under test. Equipment performed without error, no anomalies in the monitoring meters were noted and no damage to the equipment occurred.

The results of this test are tabulated on Ta51e 2. A minor resonance was noted on H22-P01/B at 53 Hz. Amplification factors for both rows of essential instruments was approximately 2 at the 53 Hz frequency.
The H22-P005 panel also showed a minor resonar'e at 53 Hz with amplification factors of 43 at the location 01 the essential instruments.
H22-P018 showed a minor resonance at the top of the panel at 14.5 Hz.
Amplification in the areas of essential instruments, however, is approximately unity. The only resonance where any amplifications to the essential instruments occurred was at 45 Hz . The amplification factors at this frequency was %2.

~~9.0 CONCLUSION~~
e All three panels were tested on the seismic . table simultaneously, and no malfunctions occurred throughout the testing. In addition to the essential instruments, all of the plumbing was carefully inspected throughout the test for leaking weld joints and loose connections. No anomalies were found. Amplification factors determined from the transmissibility plots show that considerable high vibrations are felt at the instrument locations at the resonance frequencies. The panels were, however, subjected to SSE random dual axis tests which are far more severe than the Cofrentes Required Response Spectrum and all instruments performed as required.
These panels therefore meet all seismic requirements for the Cofrentes site location.
The additional MSIV-SSE tests perfomed show that at panel resonances (from 14 Hz to 15 Hz) the g level of the MSIV plot is higher (7.49) than that of the BWR 6 Plant Response Spectrum (69 ).
