2.0 APPLICABLE DOCUMENTS 2.1 Bechtel Power Corporation Specification No. 7749-E-241Q, Revision 0F, dated September 26, 1980.

A 2.2 IEEE 344-1975, "IEEE Recommended Practices for Seismic Qualification of Class lE Equipment for Nuclear Power Generation Stations".

2.3 Vitro Laboratories, " Seismic Electrical Test Procedure" TP 3394-1032.

A 2.4 Wyle Laboratories, " Seismic Test Procedure" 541/4303/DK.

l 3.0 EQUIPMENT FOR SEISMIC TEST 3.1 The Anticipatory Reactor Trip System is contained in a Hof fman Engineering Company NEMA 12 wall-mounted cabinet enclosure approxi-mately 48 inches high, 36 inches wide, and 12 inches deep. A ccepletely assembled, operating, deliverable enclousre will be j

None 4.0 SEISMIC QUALIFICATION 4.1 The enclosure and devices will be qualified by tests in accordance with IEEE 344-1975.

Seismic tests of the ARTS enclosure will be random-mo tion, multiple-f requency, phase-independent tests with simul-taneous horizontal and vertical inputs.

The Test Response Spectra from the control accelerometers will envelop the Required Response Spectra at the required damping value. During qualification testing, the acceleration levels at specific device locations will be monitored.

The devices will be operational and electrically monitored to verify there is no degradation due to the seismic occurrence.

4.2 At least thirty days prior to testing, Bechtel/Gaithersburg, will be notified of the testing schedule and location to afford the opportun-icy to witness any or all parts of the test and subsequent inspection.

5.0 SEISMIC TESTS 5.1 The cabinet enclosure will be bolted to a vertical wall on the test table as shown in Figure 1.

Af ter the cabinet is bolted in place, accalerometers will be idstalled in the cabinet in accordance with Figure 1, and two control accelerometers will be attached to the test table.

The tested arrangement duplicates the actual plant installa-tion.

5.2 Exploratory Tests - Axis Y and Axis Z Exploratory Tests will consist of a single-axis continuous one octave l

None per minute sueep frequency search using a sinusoidal steady-state input of approximately 0.2 g from 0.5 Hz to 50 Hz to determine equipment resonances. The horizontal and vertical axes identified as Axis Y and Axis Z in Figure 1 will be tested first.

5.3 0.B.E. Proof Tests - Axis Y and Axis Z Five 0.B.E. proof tests will be conducted on the cabinet. The cab-inet will be subjected to simultaneous horizontal and vertical inputs of random-motion consisting of frequencies spaced one-third octave apart over the frequency range of 1.0 Hz to 33 Hz.

The amplitude of each one-third octave frequency will be independently adjusted in an iterative process in each axis until the Test Response Spectra (TRS) from the control accelerometers envelops the Required Response Spectra (RRS) at a damping of 2% by a spectrum analyzer.

The RRS is defined by Figure 2 for the Y Axis (horizontal) direction, and by Figure 3 for the Z Axis (vertical) direction. The cabinet will be excited by simultaneous horizontal and vertical input accelerations for a period of 30[ seconds.

Following the fif th 0.B.E. proof test, the equipment will be examined for damage and hardware will be retightened if necessary.

5.4 S.S.E. Proof Test - Axis Y and Axis Z One S.S.E. proof test will be conducted on the cabinet.

The cabinet will be subjected to simultaneous horizontal and vertical inputs of random-motion consisting of f requencies spaced one-third octave apart over the frequency range of 1.0 Hz to 33 Hz.
