II. INTRODUCTION The following tests were carried out at or under contract to Acme-Cleveland Development Company, -the research center for Acme-Cleveland Corporation. The switches tested were manu factured by Namco Controls, an Acme-Cleveland Company. The tests were carried out in order to test limit switches-to the provisions of IEEE Standards 344 ('75), 323 ('74) and 382 ('72).

These standards pertain to Class 1E safety-related equipment for use in nuclear power plants.

The tests consisted of the following parts:

1. Heat aging for 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br /> at 2000F.

2. Mechanical aging for 100,000 actuation cycles under electrical load.

/

3. Irradiation to a level of 204 megarads of gamma radiation.

4. Seismic testing to a maximum of 9.52 g's in the 1 to 35 Hz range.

5. LOCA testing to a maximum 340°F at 70 PSIG.

III. SAMPLE IDENTIFICATION From the model EA-180, Type '23, series nuclear switches, one switch with part number EA-180-11302, Rev.-D, was selected for test purposes.

The test facility reference identification number is

1. 61.

In order to verify that the short *travel mechanism was not subject to seismic failure, one switch with part #EA 180-14302, Rev. C, was selected for testing through the seismic stage. See Appendix F.

Page 2 of 11l

The test facility reference identification number for

this switch was #8 3 .

IV. TEST PROGRAM The test program will be presented in the order in which it was performed. Throughout the testing the following equip

.ment was used to determine the performance level of the units.*

A megohm meter measured the resistance between contacts when open. A test circuit measured the load current between contacts when closed. This circuit consisted of a 100 volt DC power supply, appropriate voltage and current meters, and a load bank set to pass 86 milliamps in parallel with a small current (6 ma)

-neon light.

Initial inspection. Open and closed circuit performance was measured and recorded for purposes of providing base line data. These measurements were not used in the selection of

.switches for test. Normal quality control inspection had been performed prior to shipment.

Heat aging. The heat aging test consisted of holding the unit suspended over water in a tank at a temperature of 2000F for 200 hours0.00231 days <br />0.0556 hours <br />3.306878e-4 weeks <br />7.61e-5 months <br />.+ A thermometer was placed such that the switch was between it and the heat source. This thermometer was monitored during heat aging. During the time of this test, the conduit opening of the switch was sealed so that the humid air could not penetrate into the switch via this route.

Mechanical aging. The switch was subjected to 100,000 actuation cycles in order to simulate the normal switching

• See Appendix E for calibration dates.

+Heat aging conditions were taken from ANSI Draft Standard N278.2.1 (Draft 3, Rev. 0). The correlation between these conditions and the qualified life is not known.

functions of the unit during its lifetime. The actuation was accomplished by a cam mechanism operating at 70 actuations per minute. The electrical loading during this part of the test was 500 milliamps at 100 volts DC.

Irradiation. Irradiation was performed by Isomedix, Inc.

Their certification is contained in Appendix A. Irradiation was ,carried out to a level of 204 megarads. Gamma radiation from a cobalt 60 source at 1.25 Mev. was used. The irradiation was carried out at a rate of one megarad per hour.

Seismic testing. Seismic testing was performed by Dr. Ed ward J. Walter and Associates. The complete description of apparatus and procedure is contained in Appendix B. Single axis tests were performed in each of the three axes. The test spectrum used is given in Table I. Note that either acceleration or displacement may be the independent variable.

TABLE I SEISMIC TEST SPECTRUM (INPUT MOTION)

Peak to Peak Frequency Peak Acceleration Displacement 1-4 Hz 0.6-9.52 g's 12 inches 4-10 Hz 9.52 g's 10-20 Hz 0.45 inches 20-35 Hz 9.52 g's Seismic Testing - Cross Coupling. All of the parts and assemblies of which the switch is comprised may be classified into three categories depending upon the geometric constraints upon their movement within the unit. The first category is components free to revolve about an axis but which have balanced angular masses about that :axis. The second Page 4 of 11

category is components which are free to rotate about an axis within a range the limits of which are 90 to either side of a principal axis of the switch. The third category is parts which are constrained to linear movement in a line which is -within 90 of a major axis of the switch.

The contact lever arm assembly (83) is in the first category.

As the angular moment of inertia of this component is balanced about the central axis, vibration will not result in any torque about the axis. Therefore, it is not necessary to consider this component in the analysis of cross coupling.

Components belonging to the second category are the lever shaft assembly (94), the latches (19) and the rocker arm (65).

The parts belonging to the third class are the contact carrier plate assemblies which are located at the ends of the contact lever assembly (83) and the roller assembly (75, 80 and 81).

The linear motions of category 3 components except (75, 80 and

81) and the tangential motions of the category 2 components are all within 9 of the Y axis. Therefore, a vibration with a deviation of 90 from the Y axis would cause a higher G loading along the direction of motion of these components than motion directly along the Y axis.

Therefore, the G levels used in single axis testing should be multiplied by a factor of .98 (i.e. cosine of 90) in order to compensate for possible effects due to multi-axis vibration.

Movement of components (75, 80 and 81) is within 90 of the X axis. Therefore, it could cross-couple with the Y axis movements of Page 5 of 11

the other category 2 and 3 components. The X axis movements of (75, 80 and 81) cannot cause any Y axis movements directly. It can, however, allow Y axis movements of (65) and (94). It is shown below that movements of (94) cannot occur at 10 g's due to the preloaded force of spring (107).

This conservatively simulates any cross coupling between components (75, 80 and 81) and (65).

Due-to the above considerations cross coupling is not considered limiting in this unit and, therefore, single axis vibration testing is considered suitable.

It can be seen from the data in Appendix B that the switch used in the present-qualification was not used in the seismic qualification. Switches #32, 33 and 45 which were included in the seismic testing are internally identical to the switch #61 covered in this present qualification.

The only difference between switch #61 and switches 32, 33 and 45 was the material for 0-rings, lubrication and gaskets. It was not considered necessary, therefore, to

• Blueprint specified minimum.

• • All mass is conservatively assumed to be concentrated at the end of the lever shaft assembly.

+See page 12(B) Page 7 of 11

take new seismic data on the present switch. In order to simulate the condition of a switch which has undergone a seismic event switch #61 was seismically conditioned by subjecting it to all vibrations contained in the seismic tests. Electrical load was applied during these vibrations, however, the perform ance of the switch was not monitored during this conditioning (see Appendix C).

LOCA Test. The temperature pressure profile for the test is given in Fig. 1*.

The first four days of LOCA testing was performed in a chamber of 12" height and 8" diameter. The switch was mounted in the chamber in a horizontal position such that the lever shaft pointed upwards. The switch was attached by means of a threaded pipe. Teflon tape was used for sealing the pipe threads.+ °This pipe ran through an 0-ring type feed-through in the chamber.

The electrical connections from the switch were run through this same pipe. Actuation of the switch was provided by a rotary feedthrough in the top of the chamber.

In order to produce the portions of the required test which call for pressure below saturation air pressure was applied to the interior of the switch. Air pressure was adjusted so that

-the differential pressure between the interior and the exterior of the switch was as specified. The test chamber (exterior to the switch) was held at the specified temperature under saturated conditions.

Page 8 of 11

• • The switches (32, 33 & 45) which were seismically tested had been subjected to heat aging, wear cycling and irradiation prior to seismic testing.

See Appendix G.

• The recorded pressure temperature data is presented on pages 8-11(D).

+No attempt is made to qualify the connection method. These test procedures are based on the assumption that the user will ensure that no steam enters 4 the unit via this connection during an actual LOCA.

The switch was subjected to a caustic spray during this portion of LOCA test. The flow rate of the spray was 230 cc's per minute providing the necessary coverage of .015 gallons per minute per square foot of cross-section. The-pH of the spray was maintained between 10 and 11. The spray was composed of boric acid, water, sodium thoiosulfate and sodium hydroxide, and was recycled during the entire time. Spraying was initiated follow ing the second transient temperature rise.

The switch was transferred from the high pressure chamber to a low pressure chamber following the first four days of the LOCA test. It remained in this low pressure chamber for the rest of the 30 day LOCA-period. During this part of the test the switch was sprayed with distilled water which was continuously recycled.

Two data acquisition methods were used during the LOCA.

The temperature was recorded on a strip chart recorder via a thermocouple. During the transient sections of the LOCA the digital readout from the thermocouple, as well as the reading of the pressure gage, were recorded on video tape. The data is recorded on scenes 611 and 612 of this tape which is on file in the library of Acme-Cleveland Development Company.

The switch was actuated ten times during the peak level of the second transient of the LOCA and at other times as noted in Fig. 1. Data were taken twice during the second peak level and at the conclusion of the test.

V. RESULTS During all phases of the test, the open contact re sistance of the switch remained above 50 kilohms. The closed Page 9 of 11

circuit current remained within two milliamps of the specified load. During seismic testing, the trip point (with 1-1/2 inch arm) varied by .107" or less for all units seismically tested.

Detailed performance data are presented in Appendices B,

.D and F.

VI. CONCLUSIONS Switch #61 representing revision level D of model

1. EA-180-11302 maintained a 50KCL- open circuit resistance with all other performance satisfactory during all sections of the test.

Switch #83 representing revision level C of model

1. EA-180-14302 maintained trip position within .107" of original with all other performance satisfactory throughout all sections of the test performed on-it.

The tests were carried out from June of 1977 to January of 1978.

Dear Mr. Solem:

7 This will summarize parameters pertinent to the irradiation of two switches per your Purchase Order of October 12, 1977.

The units were identified as switches 59 and 61.

The units were placed in a Cobalt-60 gamma field such the dose rate was .7 Mrad/hr. The units were exposed that for 291.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />, yielding a minimum dose of 204 megarads.

The samples were rotated and turned during exposure obtain the most even dose distribution. Irradiation to was conducted in air at abient temperature and pressure. Radiant

-heat the source heated the samples somewhat, but the temperaturefrom not exceed 110°F as indicated by previous measurements did on an oil solution in the same relative position.

Dosimetry was performed using an Atomic Energy of Canada, Ltd. (AECL), Red Perspex system with Type BC-2 readout.

Calibration of the Perspex is made by AECL using Ceric traceable to the U.S. National Bureau of Standards. dosimetry Isomedix regularly cross-calibrates its AECL system with an inhouse Harwell Perspex system, and makes semi-annual calibrations directly with NBS, using the NBS Radiochromic Dye system.

1. PURPOSE Four Limit Control Switches manufactured by NAMC0 Controls were subjected to a seismic qualification test for Class lE equipment 'to be used in nuclear-powered electrical generating plants.

The four switches are a representative sample of EA180-11302 and EA740-80100 limit switches and the seismic test results will be considered as representative of the characteristics of each switch series. The tests involved single-axis sinusoidal vibration in each of three mutually perpendicular axes parallel to the major dimensions of the switch, in accordance with 382-1972, 5

323-1974, and 344-1975. The test program was conducted by Dr. Edward J.

Walter and Associates at the John Carroll University Seismological Labora

'tory, Cleveland, Ohio. INAiCO representatives were -present during various stages of the tests and monitored parts of the test program.

3. TEST EQUIPMENT The test equipment consisted of two different shake tables. The first shake table was a mechanical device for large amplitude - low frequency vibration. Maximum peak to peak displacement was twelve inches, giving a single amplitude of six inches. Displacements down to .025 inches single amplitude could be achieved. The mechanical shake table was used to test over the frequency range 1-20 Hz. The second device was an electro-dynamic shake table for small amplitude high frequency vibration. Peak to Peak displacement up to 0.4 inches could be achieved. The electrodynamic shake table was used to test over the frequency range 20-35 Hz. Both shake tables were monitored for wave form by an accelerometer mounted on-the table.

During the test procedure the switch was energized electrically with 125 volts DC at 1/2 amp. and monitored continuously for contact opening of 2 milliseconds or greater. The switch was tripped from the actuated position to the unactuated and back during the test procedure and monitored for contact opening.

Page 4 of 13 (B)

4. SEISMIC TEST PROCEDURE Each switch was individually mounted on the shake table with one of its major axes parallel to the direction of table motion. After comple tion of this test the switch was reoriented on the table with its second

,major axis parallel to the table motion, and similarly for the third major axis. Special fixtures for mounting the switches and activating them had to be fabricated.

Part I - Resonance Search In each orientation each switch was subjected to a continuous sine sweep from 1 to 35 Hz at a rate of one octave per minute. This sine sweep was run as follows:

Frequency Displacement Hz inches 1-10 1.0 10-35 0.01 Part II - Fragility Test In each orientation, each switch was subjected to a sine dwell test in 1/3.octave bands over the frequency ranges 1-35 Hz.. The switch was vib rated for a minimum of 60 seconds at each dwell point, beginning with 15 seconds of vibration in the unactuated position. The switch was then actu ated by a manual-tripping device and vibrated for 30 seconds in the actuated position. After this, the switch was released by the manual tripping device and vibrated for 15 seconds in the unactuated position. The switch was the double throw type.

During the vibration test, the switch contacts were monitored for opening by a light indicator circuit. If the light indicator circuit sig naled a contact opening, the duration of opening was then monitored on an oscilliscope. The criteria for seismic failure was a contact opening of 2.0 milli-seconds or greater. Both the Normally Open (NO) contacts and the Nor mally Closed (NC) contacts were monitored during the tests.

The trip angle of each switch was also monitored during the vibra tion test. This was done by monitoring the switch angle position on the oscilliscope. The variation in the trip angle position should not exceed o.06o inches while being subjected to the vibration test.

Page 5 of 13 (B)

The dwell test was run in 1/3 octave bands at the following frequencies and vibration specifications.

Dwell Points Frequency Hz Vibration Specifications 1.0 Il\ f* 4 1.25 Displacement - 12.0 inches pp.

16.0 20.0 25.0 20 < f < 35- acceleration 9-52 g 32.0 Displacement - 0.4.inches pp.

The table motion was constrained to specific displacements as specified or as required to produce the specified acceleration. Wave shape was monitored by an accelerometer mounted on the table. The

.planes of vibration relative to the switch configuration are shown in the following diagram and each switch was subjected to 54 distinct vibration tests.

Page 6 of 13 (B)

5. TEST RESULTS All switches performed with no malfunctions in the sine sweep from 1 Hz to 35 Hz. Also, no resonances were observed during the sine sweep test.

In the sine dwell test of 60 second duration during which the switch was actuated and released, no malfunctions were observed.

The test circuit did indicate a reaction to-a small voltage change which when monitored on the- oscilloscope was less than 2.0 milli seconds and hence not within the definition of switch failure.* The various frequencies for each switch at which such an indication occurred is shown in the following table.

f Switch Hz 33 32 45 3b 1.0 x x 1.25 x x 1.6 x x x x 2.0 x x x 2.5 x x x 3.15 x x 4.o x x

Page 7 of 13 (B)

• See page 13(B)

The trip position of each of the switches remained within the required limit and at no time deviated from the original position by more than 0.060 inches at the end of the two inch arm. In fact, the changes noted were small com~pared to the tolerance limit.

The test results are facility limited and therefore do not indicate the ultimate capability or the vibration level at -which switch failure will occur. Each switch was subjected to 54 distinct vibration tests which lasted for 60 seconds or greater so that minimally each switch was vibrated for 54 minutes. Checks for frequency and wave shape and other manual opera tions extended the total vibration time by perhaps a factor of two or three.

Page 8 of 13 (B)

6.CONCLUSION~S The )Jinit control switches performed satisfactorily without failure when vibration testea in accord with the specifications pre sented herein.

No contact opening-of' 2 mailli-seconds or greater occurred during the tests.

No resonance frequencies were noted during the test.

-II ACJW/E-CLEVELAAIL: DE VEL OIPNVEN T C OMPANIY Behavior Of The Test Circuit The test circuit was designed to detect switch openings of more than a pre-set time. For the purpose of these tests the time was set at 2 milliseconds. During the seismic tests it was reported that the circuit was triggering. Therefore, personnel from Acme-Cleveland Development Company observed the situation.

It was found by use of an oscilliscope that the circuit.

was responding not to contact openings but to small changes in voltage due to increases in contact resistance as the contacts moved over one another. Although the decrease in voltage may

.have lasted for considerable times, no contact openings of more than 2 milliseconds were observed in that instance. At that point it was decided that whenever the circuit was triggered the oscilliscope would be used (by Dr. Edward J. Walter & As sociates' personnel) to determine if there was a contact opening of more than 2 milliseconds or not.

• TELEPHONE: (216) 729-7415 Vibration Tests of Limit Control Switches NAICO Controls An Acme-Cleveland Company "November 1977 SWITCIMS TESTED Switch No. 59, EA 180-11302 Switch No. 61, EA 180-1132 *

'VIBRUTION TESTS The switches were subjected to the following tests:

I - Fragility Test Frequency Vibration RZ Specif ications 1.25 Displacement - 12.1 inches pp giving 9.52 g's acceleration 1.6 at 4 nz.

2.0 2.5

• 3.15 4.0 Acceleration 9.52 or greater 5.0 Displacement - 8.0 inches pp.

6.3 Displaccment -'5.0 inches pp

.,8.0 Displacement - 3.0 inches pp 10,0 Displacement - 2.0 inches pp

• 12.5 Displacement - 0.45.inches pp 16.0 as above 20.0 .s above 25.0 Displacement - 0.1.0 inches pp 32.0 giving acceleration 9.52 g's or greater.

• This switch was manufactured to a bill of materials corresponding to model EA-180-11302 Page 1 of 2 (C) 4.

II - Plant Induced Vibration Simulation The switches were vibrated at a non-resonant frequency, 100 Hz at an acceleration 1.3 g for a total of 10 cycles, one third of the total cycles in each component, X, Y, and Z.

Component Frequency Acceleration Hz g's X "100 1.3 Y 100 1.3 Z 100 .. 1.3 The switches were tested in each of three mutually perpendicular

'directions parallel to the major axes of the switches. In each orienta tion a fragility dwell test and a plant induced vibration simulation test were made.

The dwell test was run for a minimum of 60 seconds duration,. beginning with 15 seconds of vibration in the unactuated position. The switch was then actuated by a manual tripping device and vibrated for 30 seconds in the actuated position. After this, the switch was released by the manual tripping device and vibrated for 15 seconds in the unactuated position.

".he plant induced vibration simulation test was run for a minimum of 10 cycles in all three components. Each component, X, Y, and Z.was

Subjected to one-third of the total number of cycles, e.g. 1/3 x 10 cycles.

-The switches were double throw type and were energized electrically at 125 volts at 1/2 amp. during the tests. Each switch was subjected to 51 distinct vibration tests, 48 of these at a minimum time of 60 seconds each and three of these at a minimum time of 56 minutes each.

December 19, 1977 QUALIFICATION OF IEEE STANDARD 323, 344 AND 382 USING WESTINGHOUSE LOCA PROFILE LIMIT SWITCH #61 The switch passed the heat aging, wear cycle, irradiation, seismic and high pressure LOCA test. Checking the switch on 12/16/77, after the low pressure and temperature LOCA test at 10 PSI and 200 0 F, the open contact resistance was 50 Kohms.

There was a 2.5 to 3.5 Milliampere current leakage on the open contacts. The closed contacts passed .086 amps current.

The switch was heat aged at 200°F in a high humidity chamber from 9/22/77 to 10/3/77.

The open contact resistance on a Meggar instrument measured above 1000 Megohms (Infinity) before and after the heat age test and the closed contacts passed a current of .086 amps at 100 volts DC.

The switch was wear cycle tested for 100,000 cycles at 70 RPM using a cam to actuate the lever arm, The load on the switch was .5 Amps @ 100 V.D.C. The switch was wear tested .from 10/3/77 to 10/4/77.

The open contact resistance was over 1000 Megolms (Infinity) and the closed contact current was .086 amps before and after the test.

The switch was irradiated at Isomedix, Inc. from 10/6/77 to 10/26/77. The switch was irradiated at Isomedix, Inc.

with a cobalt 60 source. The total irradiation appl.*ed was

'04 Mrads with an energy level of 1.25 Mev. at .7 Mrad/hour rate.

The open and closed contact resistance and current were the same value as before the test.

The switch was seismic tested by Dr. Edward J. Walter & Associates.

The seismic tests consisted of resonance scan, fragility test and plant induced vibration simulation.

The switch was LOCA tested on 11/15/77 in a high pressure chamber and on 11/19/77 was removed from the chamber and installed in the low temperature and pressure chamber until 12/15/77. The LOCA was extended to 12/16/77 because the low pressure and temperature chamber was down for repair for part of a day.

The open contact resistance was above 1,000 Meohms (Infinity) before both LOCA spikes of 340°F and 70 PSI differential pres sure, but when the temperature and pressure were at the maximum the resistance dropped to a low of 10 Meohins on the first and 800Kohrns on the second spike. (7<

spike ,

Page 14 of 15(D)

When the chamber temperature was decreased to 250 F the contact resistance was 900 Megohms. open The pipe that held the lead wires to the exterior was removed exposing the interior of the switch to connector the outside

(~ atmosphere surrounding the chamber. The resistance then in creased beyond 1000 Megohms (Infinity) and remained above 1000 Megohms until the switch was removed from the chamber and installed in the low temperature and pressure chamber.

The switch lever arm was activated on the 14th day of the LOCA 11/29/77 while in the low pressure and temperature LOCA 200'F and 10 PSI. The activation was according to IEEE specifications.

The switch was removed from the low temperature and pressure chamber at the end of the LOCA on 12/16/77..

When removing the sealed connector pipe moisture had entered the switch around the contact block but there was not enough moisture to drip from the switch.

• The closed contacts passed .086 amps current and there slight leakage of current, 2.5 to 3.5 Milliamps across was a the open contacts.

The resistance across the open contacts had dropped to 50 Kohms.

, The switch was bubble tested with 12 pound of air and was no detection of leakage.

The torque to remove the top cover screws was 8 to 13

'while the torque required to remove the bottom lb. inches cover screws was 4 to 8 lb.inches.

The top cover gasket was moist and had a tacky substance inside surface bridging from one center screw hole on the to the opposite center screw hole.

The bottom gasket was cracked at the center moisture was present in the bottom housing. housing support and There is a pos sibility that leakage occurred at one or both bottom cover screws at the connector end of the switch. When the gaskets dried they became very brittle.

The contacts had a residue on these surfaces but were reasonably clean. The contact block was also clean but held film of moisture.

The boot cracked when removing it from the spindle.

The spindle shaft 0-ringwas in good condition and was resilient.

• The oil was present on the shaft and 0-ring.

The grease was present on all sliding surfaces.

APPENDIX F

'Supplementary Testing For Short Travel Switches

Those switches of the EA-180 series which contain a short travel mechanism differ internally from the standard travel versions in some respects. It was, therefore, felt that it was necessary to test a short travel model up through the seismic portion of the test in order to verify that the internal mechanism of this switch was not subject to seismic failure.

The tests conducted were the same as those conducted on the switch #61 in the body of the report except that the LOCA tests were not performed.

The short travel switch which was tested (#83, Model EA 180-14302, Rev. C) maintained optimal electrical performance throughout all portions of this test. During the seismic test ing the trip position of this switch was observed to change as noted in the seismic report. The maximum change was .107" and the direction of change was such that the switch would actuate earlier in the tripping cycle than it had prior to the seismic testing.

Cross coupling tests were not necessary for this switch as they were for the long travel mechanism. This was because the parts #75, 80 and 81 of the normal long travel mechanism (see page 5 of the main body of the report) are not present in this switch, and part 62 which replaces these parts is not sub ject to movement in the X axis.

It was not considered necessary to LOCA test this switch because short travel versions of the switch covered in the main body of this report will be built with identical sealing mechanisms (i.e. gaskets and 0-rings) to switch r61.

Dear Mr. Solem:

This will summarize parameters pertinent to the irradiation switches per your purchase order no. DC-97214, dated January of three' 12, 1978. The units were identified as switches 81A, 82A, and 83.

~The switches were placed in a cobalt-60 gamma field at a dose rate of 1.2 Nrad per hour. The' switches were exposed for 170.0 hours0 days <br />0 hours <br />0 weeks <br />0 months <br />, S yielding a minimum dose of 204 megarads.

,Dosimetry was performed using an Atomic Energy of Canada Limited (AECL) Red Perspex.system with Type BC-2 readout. Calibration the Perspex is made by AEC, using Ceric dosimetry traceable of U.S. National Bureau of Standards. Isomedix regularly cross to the calibrates its AECL system with an inhouse Harwell Perspex and makes semi-annual calibrations directly with NBS, system, using the NBS Radiochromic Dye'system. A copy of the dosimetry correlation re port is available upon request.

Irradiation was conducted in air at ambient temperature and pressure.

Radiant heat from the source heated the samples somewhat, temperature did not exceed 100 0 F, as indicated by previous but the ments on an oil solution in the same relative position. measure Irradiation was initiated on January 15, 1978, and was completed on January 26, 1978.

• TELEPHONE: (216) 729-7415 Vibration Test of Limit Control Switch NAMCO Controls An Acme-Cleveland Company January, 1978 Reference A detailed description of the vibration testing equipment and test procedures is given in our report of June, 1977, Seismic Qualification Test of Limit Control Switches, prepared for NAMCO Controls.

UURRENT SWITCH TEST Switch No. 83, EA 180-14302 VIBRATION TESTS The switch was subjected to the following tests:

I - Fragility Test Frequency Vibration Hz Specification 1.0 Displacement - 12.1 inches pp 1.25 giving 9.52 g's acceleration 1.6 at 4 Hz.

2.0 2.5 3.15 4.0 Acceleration 9.52 or greater 5.0 Displacement - 8.0 inches pp 6.3 Displacement - 5.0 inches pp 8.0 Displacement - 3.0 inches pp 10.0 Displacement - 2.0 inches pp 12.5 Displacement - 0.45 inches pp 16.0 as above 20.0 as above 25.0 Displacement - O.40 inches pp 2..0 giving acceleration 9.52 g's or greater.

Page 9 of 1 (F).

II -Plant Induced Vibration Simulation The switch was vibrated at a non-resonant6 frequency, 100 Hz at an acceleration 1.5 g for a total of' 10 cycles, one third of the total cycles in each component, X, Y, and Z.*

Test Procedure:

The switch was tested in each of three mutually perpendicular directions, designated X, Y, and Z, parallel to the major axes of the switch. In each orientation, the fragility dwell test and the plant induced vibration simulation test were made.

In the Fragility Dwell test the switch contacts were monitored.

Both the Normally Open (NO) contacts and the Normally Closed (NC) contacts were monitored for seismic failure by means of a light indicator circuit. No seismic failure occurred during the tests.

The trip angle of the switch was also monitored during the test at both the normally Open (NO) contacts and the Normally Closed (NC) contacts. The Normally Open (NO) contacts were monitored first.

The switch was actuated and subjected to vibration for a minimum of 30 seconds. Next, the Normally Closed (NC) contacts were monitored with the switch unactuated and subjected to vibration for a minimum of 30 seconds. Total vibration time was a minimum of 60 seconds.

This procedure was repeated for each frequency of the fragility dwell test.

The trip position remained within 1/16 inch throughout the test procedure with the following three exceptions:

Changes in Trip Position which exceeded 1/16 inch Y-c omp.

Frequency Total Change Hz :in inches 16 .107 early 25 .080 early 32 .107 early Pa'ge 10 of 11(F)

In the Plant Induced Vibration Simulation test, the switch was vibrated at a non-resonant 6 frequency, 100 Hz, at an acceleration of 1.3 g, for a minimum of 10 cycles. Each component, X, Y, and Z was 6 subjected to one third of the total number of cycles, e.g. 1/3 x 1lO cycles.

The switch was a double throw type and was energized electrically at 125 volts at 1/2 amp. during the test. It was subjected to 51 dis tinct vibration tests, 48 of these at a minimum of 60 seconds each and three at a minimum of 56 minutes each.
