SUMMARY
Aluminum Electrical Conduit Configurations, as described in Paragraph 5.0 and
- hereinaf ter called the specimens, were subjected to a Seismic Simulation Test Program a_s required by the Tennessee Valley Authority Purchase Order Number 56071A and their Test Plan Number CEB-BN-1002, Revision 0, dated 2-18-86.
The test program was performed in twelve test series from February 24 through
' March 12, 1986.
~
The test program consisted of single-axis resonance search testing along the The ;
orthogonal specimen axes, and triaxial rancom multifrequency testing. i specimens were instrumented with accelerometars and strain gages, as required, to I
- monitor the specimens' response. Additionally, specimen damping factors were determined where required.
- It was demonstrated that the specimens possessed sufficient structural integrity to withstand the prescribed qualification level seismic environment. ..

the paragraphs below.
Each conduit shall be filled with one or more non-energized free-ended '-
electrical cables to a fill ratio of approximately 40 percent. The weight of each conduit configuration shall be determined prior to ,l ,
testing.
t-Each configuration shall either be tested separately or in conjunction (if possible), depending on the sire, with another configuration geometry, and availability of the configuration. -
5.2 Specimen Mounting and Orientation -
Each specimen shall be mounted on a Wyle-supplied test fixture utili:ing unistrut supports and TVA-supplied clamps, which shall be torqued to ,
TVA-specified values. Each specimen shall be oriented such that its orthogonal specimen axes are colinear with the test table's axes of -
excitation. Mounting of the specimens shall simulate their actual in-
service mounting configurations as closely as practical.
5.3 Resonance Search Testing The specimens shall be subjected to low-leiel (approximately 0.2g) sine ,
sweep tests in the specified orthogonal axes, performed over the frequency range of 1 Ez to 40 B: to establish their resonant frequencies. .
The sweep rate shall be one octave per minute. Transmissibility plots of -
the specimen response accelerometers shall be provided.
NOTE: Prior to any testing, the test fixture shall be subjected to a resonance search test to verify that it is resonant-free below 12 .

For the configurations for which damping is to be de ter:ained , the following procedure shall be followed:
The test table shall be excited trith a 0.3g sine dwell input waveform at a frequency that equals the resonant frequency of the specimen under test
, (as determined during the resonance search test procedure outlined in Paragraph 5.3). The input motion of the table shall be of sufficient duration to excite the specimen to resonance. The table motion then shall be terminated by suddenly stopping the table.
, The damping values for each specimen shall be calculated from the recorded response decaying sinusoidal motion of the specimen, employing
- the Logarithmic Decrement method:
. Damping =

, \ A/
. where X = Amplitude at initial cycle
~
X = Amplitude at n g cycle n
fn = Natural Log
. 5.5 Randon Multifrequency Testing Each specimen shall be subjected to 30-second duration triaxial multi-
, frequency random motion which shall be amplitude-controlled in one-third octave bandwidths spaced one-third octave apart over the frequency range of 1 to 40 H:. Three simultaneous, but independent, random signals shall be used as the excitation to produce phase-incoherent motions in the 1 vertical and two horizontal axes. The amplitude of each one-third octave
, bandwidch shall be independently adjusted in each of the three axes until the Test Response Spectra (TRS) envelop the Required Response Spectra (RRS). The resulting table motion shall be analyzed by a response 1,
- spectrum analyzer at 5% damping and plotted at one-sixth octave ~
intervals over the frequency range of 1 to 200 H:.

The calculated damping values (including accelerations and displace- -

6.5 n=r*= Multifrequency Test Procedure The specimens were subjected to 30-second duration triaxial multif re- .
quency random motion which was amplitude-controlled in one-third octave bandwidths spaced one-third octave apart over the frequency range of 1 to "
40 Hz. Three simultaneous, but independent, random signals were used as "
the excitation to produce phase-incoherent motion in the vertical and two horizontal axes. The amplitude of each one-third octave bandwidth ..
was independently adjusted in each of the three axes until the TRS enveloped the RRS. The resulting table motion was analyzed by a response ~
spectrum analyzer at 5 percent damping for the OBE tests and the SSE ,
test, and plotted at one-third octave intervals over the frequency range of 1 to 200 Hz. -
Each test configuration was subjected to a qualification level SSE test to envelop the Browns Ferry Nuclear Power Plant 5% RRS shown in Figures ,

specimen failure occurred or the test machine input limitations were reached. -

livel) environment without any damages.
However, during the increased level testing of some test configurations, -
some permanent deformations of some specimens were noted. Additionally,
- some clamps came loose and some conduits rotated due to clamp loosening.
Details concerning these occurrences are contained in the test run descriptions of the random multifrequency tests contained in Table I and n in Appendices IV through XV.
