Box 11318 + Lynchburg, Virginia 24506 m_. 9 ( Telephone-804-528-4400 + Telex-82-9448 TEST REPORT L 1.0 GENERAL The following tests were conducted to determine the capability of Limitorque actuators to withstand high frequency vibrations up through 100 hz caused by hydrodynamic loadings in a boiling water reactor f nuclear power plant. 2.0 DISCUSSION It is generally agreed within the industry that random multi-frequency biaxial testing most closely duplicates the actual high frequency acceleration the actuator would see during hydrodynamic loading. Due to the complexity of the piping systems and the varied locations of {, the actuator, proper RRS curves could not be developed and it was decided to adopt the much more conservative mode of testing of sine-beat dwells at 1/3 octave intervals from 2 to 100 hz. Actuator resonances would not be a consideration for random multi-frequency ( biaxial testing, but would have to be considered when choosing represen-tative units for the more conservative sine beat testing at 1/3 octave intervals. Due to this fact, it was decided to check the resonance points below 100 hz on all the actuator sizes in question. Since it has been determined that the motor mounting flange is the most sensitive area in seismic testing, simplified stress static calculations ( were m de. l Automated Velve A&enes and Jacks for Industry l

2.0 (cont) ( The test units were chosen on the basis of considering the worst case combination of resonant frequencies and stress levels of each actuator. 3.0 RESONANCE SEARCH Prior to start of actual testing, it was detemined that resonance search by use of a shaker table might possibly create delays in the overall testing program. An alternate method of detemining resonance by modal analysis could accelerate the schedule. An S96-0-25 was sent to the test lab to check resonant frequencies of the actuator by both modal analysis and a resonance survey by applying a.75 g input at a sweep rate of 2 octaves per minute from 5 to 200 hz to 5 hz. Since relatively close agreement was established between b the two methods of detemining resonances, modal analysis was considered valid and was used in detemining resonanus of the remainder of_ the actuators. f Due to the fact that resonance information was available on the SM-3 from Report B0085, the SPE-3 was not subjected to a resonance search on this test. 4.0 TEST PROCEDURE The test procedure used is included in Appendix A. Due to lack of prior data in testing Limitorque actuators at high acceleration levels at fmquencies in excess of 33 hz, it was decided ( to attach special supports to the limit switch finger base on two of the four trains. Should the finger base prove to be sensitive to L high acceleration levels at higher frequencies due to resonance or i L 1L ,__e

k 4.0 (cont) 3 other reasons, this permits continuation of the testing with a potential ( design modification being tested. Testing proved the standard switch without the addition of the special supports passed the hydrodynamic k test and therefore the actuators enn be used as originally supplied. 5.0 CHOICE OF TEST IAIITS 1 A joint engineering review by Limitorque and Bechtel lead to the following conclusions and choice of test actuators. The most sensitive area to acceleration loading is the connection of the i Since this area has a relatively complicated motor to the actuator. l configuration and since this joint is the same in design concept on all size actuators varying only in physical size and metal thickness, a sispie calculation was made. This calculation, although not providing actual stress levels, provided relative flange strengths which pennitted selection of the " worst case units". The SM-2 actuator had the highest stress level, approximately 60% over the SM-00 and SMB-0 actuators. Information at the time of evaluation showed the dominant resonances of actuators of the size SE-3 and smaller were close to or in excess of 100 hz with resonances being [ detected on the SM-4 below 100 hz, but well above 33 hz. Resonance was detected on the S2-5 at 28 hz. On this basis, it was agreed that l hydrodynamic testing should be conducted on the SMB-2 and SM-4 actuators. The SM-000 was also included, primarily to check the Modutronic 10A included in this unit. Decisions were then made to include an SM -1 l. actuator in the test program to add another mid-size unit for additional confidence level. g [

L, b' 4 5.0 (cont) A joint analysis (as shown below) was made by Bechtel and Limitorque, which showed the testing of the SM-5 was not necessary. A. Acton's modal analysis detecteu a resonance in the SM-5 at 28 hz. B. An earlier seismic test subjected an SM-5 Limitorque actuator to 6 g acceleration at 28 hz with the actuator operating properly during the seismic dwell. C. The SM-4, which was subjected to hydrodynamic testing had resonant frequencies slightly above the SMB-5 but below the 100 hz max test level and subsequently passed the hydrodynamic test without problem. D. Due to the generic family relationship of all Limitorque actuators, it is contended that the SM-4 and 52-5 actuators would react similarly to high frequency sine beat testing. E. On this basis, the SM-5 is considered to have the capability of withstanding 6 g acceleration to frequency levels of up to 100 hz. The SM-000-2/H0BC and SM-00-15/H2BC ninety degree actuators were I i also jointly reviewed. The most sensitive area to acceleration loading in this case is the adaptor that mounts the SM actuator to the HBC ninety degree actuator. Since the S2 -00 is much heavier than the SM-000 and the highest stressed area of the adaptors being l of the same cross section, the SM-00-15/H2BC was chosen as the test i unit. 6.0 SUMARY OF TEST LEVELS Actuator Size Acceleration Level SM-000-2/ Mod.10A 10 g i S2-1-60 10 g l

7.0 CONCLUSION

The actuators tested consisted of units which, in relation to high frequency acceleration load testing, included the most detrimental attributes of the generic family of actuators. Since the actuators performed all functions with no indication of malfunction during the acceleration load testing, the entire generic family of actuators, SM/SB/SBD, is considered qualified for high frequency hydrodynamic ~ loading (per test procedure) to 10 g in the size range of 52-000 to 3, 7 g for the SM-4 and 6 g for the S2-5. The SM-00-15/H2BC was tested with limit switches that included special brackets. In reviewing the accelerometer strip charts, it was noted that comparing the acceleration readings of the SMB to the acceleration readings of the control accelerometer that there was no multiplication. ( Since the limit switches in all size actuator are of the same configu-ration and the maximum acceleration loading of the SM-00 did not exceed 8 g, the standard limit switch would survive the vibration testing as proved in tests of the other units. The SM-00-15/H2BC envelopes the combinations of an 52-00 mounted on an HlBC or H2BC or an 52-000 mounted on these same ninety degree units t 3 and on an H0BC. These units art considered qualified for high frequency hdrodynamic loading of up to 8 g as defined in the test procedure. e

Background
Prior to any hydrodynamic loads test, the Limitorque SMB-1-60-DC valve actuator was mounted on a test fixture to provide simulated valve seating loads during sine beat portions of the tests. A check of output torque after all testing was campleted indicated an average " closed" value of 1140lb-ft and an "open" value of 1080lb-f t (average). The lower geared limit switch (of the 4-train assembly) was replaced prior to any I testing with a geared limit switch assembled with a Navy shock bracket. i h. E l 'L i
Project 681021 Page 2 L~ The actuator assembly was scanned for resonances (in esch axis) before beginning sine beat tests. All test results froma testa performed at Acton Labs can be ( found in the referenced reports accompanying this susmary. At the conclusion of hydrodynamic loads testing, the SMB-1-60-DC actuator was manually clutched and operated through a full open stroke-close stroke cycle. No apparent damage was detected. i conclusion The Limitorque valve actuator SMB-1-60-DC performed its function (as specified in test procedures for Project 9681021) with no apparent malfunctions or physical damage. Both limit switches performed without failure. Limit switch " drop-out" witnessed during portions of the sine beat test is due directly to improper contact made between the rotor and finger assembly. (Nor-mal gap between the finger and the "L" bracket of the finger assembly, with 7 asasurement made at the finger assembly spring, should be.020/.040 inches.) ~ Any lessening of spring tension would result in contact switch chatter.

Background
Prior to any hydrodynamic loads test, the Limitorque SMB-1-60-DC valve actuator was mounted on a test fixture to provide simulated valve seating loads during sine beat portions of the tests. A check of output torque after all testing was completed indicated an average "closa!" value of 1140lb-ft and an "open" value of 1080lb-ft (average). The lower geared limit switch (of the 4-train assembly) was replaced prior to any + testing with a geared limit switch assembled with a Navy shock bracket. a [. L = --=

Background
Prior to any hydrodynamic loads testing, the Limiterque SMB-00-15/H2BC was mounted on a test fixture to provide simulated valve seating loads during sine beat protions of the tests. Post test torque calibration checks indicated an average torque in the " closed" direetion of 810lb-f t and an averaga torque in the "open" dir-L ection of 860lb-ft. ~ lL
Proj;ct #681021 Pag) 2 Se top geared limit switch (rotors 1 & 2) were replaced with a switch ( modified with Navy shock bracket and micarta and plate. The bottom switch contained the standard Navy shock bracket only. Tt.e assembly was scanned for resonance (in each axis) before beginning sine beat tests. All results from tests performed at Acton Laos can be 'found in reports acccumpanying this summary. At the conclusion of hydrodynamic loads testing, the SMB-00-15/d2BC actuator was manually clutched and operated through a full open stroke-close stroke cycle. Ho apparent damage was detected. Conclusion ne Limitorque SMB-00-15/H2BC successfully performed its function (as specified in test procedures for Project #681021) with no apparent mal-function or hysical damage. h- -M Chas. H.

The resonance survey was conducted in each of three (3) mutually perpendicular axes with a low-level sinusoidal input. 2.2 Sine Best Test Requirements The purpose of the sine beat test specified in Section 3.4 was to determine the actuator's ability to withstand the sine beat vibration without evidence of = mechaaical damage, deterioration, or interference with proper operation. i i 16511 10 - L Report No. L 3 Q_ ) ~ L em componAtum i
y ? ( 3.0 TEST PROCEDURES 3.1 Test Mounting r The SMB-00 15/H2BC actuator was bolted to an aluminum plate test fixture such that the actuator would be limited by the torque switch in the seated position. The actuator / fixture assembly was mounted on the Acton Environmental Testing Corporation electrodynamic shaker for the resonance survey and for sine beat testing,above 12.5 H2. The actuator / fixture assembly was mounted on a single-axis seismic shaker table for sine beat testing from 2 to 12.5 Hz. I 3.2 Test Monitoring During all vibratien testing, the SE -00 15/H2BC actuator was monitored with accelerometers to determine its structural response. Three (3) triaxial groups of accel-erometers monitored the actuator response and one (1) tri-axial group of accelerometers was attached to the test fixture to monitor the test input. The accelerometers were located as seen in the chart on the following page. L 1 16511-10 Repr.i No. L. ~~~" 4 L 4L

In each axis, the l resonance survey consisted of a 0.75g sinusoidal input at i frequencies from 5 to 100 Hz and a sweep rate of two (2) l or,taves per minute. The actuator was not operated during i the resonance survey. 3.4 Sine Beat Test 1 The sine beat test was conducted in each of three (3) mutually perpendicular axes. In each axis, the sine beat ~ test consisted of an amplituda-modulated sinusoidal input 1-( with pauses between the beats applied at each test frequency. m The sine beats at each test frequency included five (5) i, anplitude-modulated beats with fifteen (15) cycles per beat at the test frequency, with a sufficient pause between beats to preclude any superposition of motion. l The sine beat test was perfonned at each center frequency of the 1/3 octave bands from 2 to 100 Hz and at each resonant frequency below 100 Hz as detennined by the qw resonance survey in each axis. p Report No. 16511-10 6 P898 Acrom comonaam L
( 3.4 Sine Beat Test (continued) The sine beats above 12.5 Hz were performed on an electrodynamic shaker table. The sine beats at frequencies from 2 to 12.5 Hz were performed on a hydraulic seismic vibration system. All sine beats were applied with 8g peak accelerations except where limited by hydraulic shaker capabilities at low frequencies. The shaker table limits for the horizontal and vertical directions., for sinusoidal inputs, are as follows: HORIZONTAL DIRECTIONS Frequency Table Limit i 2 Hz ------------ 4g 2.5 Hz ------------ 4g ( 3.2 Hz ------------ Sg 4.0 Hz ------------ Sg

Virginia 24506 ( Telephone-804-528-4400 + Telex-82-9448 ADDENDUM A SEISMIC QUALIFICATION ENVELOPE SMB & SMB/HBC ACTUATORS 1.0 Introduction The entire line of Valve Actuators, types SMB/SB/SBD/SMC/HBC is a generic family, all constructed of same materials and designed, s same concepts, tolerance and stress levels with physical size varying as a function of rating. The same principle applies to the electric motars used with our Actuators. Past studies have shown that the Valve Actuator weight is a mathematical function of torque and further that the largest motor permissible on a specific Actuator is nominally a fixed percentage of the overall Actuator weight, further supporting the generic family concept. This Seismic Qualification document was created to supoort our generic enveloping used in our various Environmental Qualifications. Primarily, seismic consideration directs itself to a weight distribution problem and resolves into the necessity of checking the adequacy of various connecting flanges. The Seismic Qualification document is a group of seismic tests conducted on units that are considered to contain the typical ( Autorrwtud Valve Operators and Jacks for Industry -.. ~ - - - - - ~ ~ - -
I . Sheet No. 2 ~ LIMITOROUE CORPORATION (~' ( l.0 Continued and worst weight distribution that would provide the most severe loading on connecting flanges during seismic excitation, thereby ~ providing a generic envelope for seismic qualification. ~ Based on the generic family concept, the following applies to Seismic Qualification: A. Since all Limitoque AC and DC equipment respond and are generically equivalent with regard to seismic excitation, tne AC and DC seismic test data would be mutually supportive of each other. B. Seismic tests on SMB/HBC assemblies can be used to qualify the SMB Actuator to the seismic level obtained from accelerometers on the SMB mounting flange as well as qualify the SMC actuator and the HBC ( manual unit to the seismic test levels. C. In all environmental qualifications, 600376A, 600456, B0003, & B0009, a mid-size valve actuator was seismically aged prior to being subjected to environmental qualification. Based on the successful completion of additional seismic tests, which were &ne to verify the generic family l concept, it has been demonstrated that the environmental testing qualification can be extended to all size units. ('i t_ __
Shret No. 3 LIMITOROUE CORPORATION b 3.0 Type Test Procedure 3.0.4 In the seismic testing we have performed, we used several test facilities with these companies having both mechanical and hydraulic shake tables. Some of the test data from the mechanical table illustrate slight indication of cross-coupling, however, shows no sign of resonance. During our progress of this seismic testing, we evaluated the mechanical table and found that the slight signs of cross-coupling were in the table itself and not the Limitorque Actuator. Both SMB and SMB/HBC Valve Operators show lack of resonance in frequency ranges of 2 hr to 34 hz. Results of the resonance (' searches are included in our seismic reports. As an example, refer to Aero Nav Report 5-6167-5 and compare input cgainst column D on page 6, input against column C on page 8 and input against Colunn C on page 10. The " shake table" used for this test is unstable at 2 and 3 hz so a resonance search was not conducted at this frequency. However, the test data indicates lack of resonance below 4 hz, because of the lack of acceleration build-up l in response as is normally experienced as resonance { is approached. b
Sheet No. 4 LIMITOROUE CORPORATION 3.0.4 Continued Further, recent tests conducted on SMB and SMB/HBC Actuators using a hydraulic " shake table" show no resonances or cross coupling exists in the frequency of 1 to 33 hz. Acton Environmental testing Corporation reports No. 13732-1,13732 and 14331 illustrates the lack of resonance and/or cross coupling within this frequency range. Accelerometer charts, that are light sensitive and not capable of being reproduced, are available for audit. 3.0.5 To provide reasonable fixturing (low silhouette) to insure dynamic stability of the seismic testing machine, the stroke of the valve actuator is substantially reduced (for seismic test only) maintaining the torque seat feature and reducing stroke time. The actual stroke time during seismic aging is unimportant since the intent is to age the unit by seismic vibration with operation merely proving the Valve t Actuator capable of operating, providing the required torque and thrust, which has been demonstrated. 3.0.6 The acceptance criteria for seismic testing is proper operation of the unit during seismic dwell, torque tripping at close and limit switch tripping at open and also that there is no visible signs of overstress at the conclusion of the test. Signs of overstress means lack of any visible difference in equipment or performance compared to the unit prior to the seismic test, which would encompass cracks, bent shafting or other permanent deformation that could be noted by eye. (
=
Sheet No. 5 LIMITOROUE CORPORATION ( 3.0.7 On the provision the assembly contains no resonance and the " shake table" is not imparting a rocking motion, there would be no additional acceleration that could cause contact chatter of an SMB/HBC over the seismic tests conducted on SMB units due to longer lever anns. The seismic tests we have conducted qualify our units seismically to g levels indicated when the seismic excitation is imparted to tne mounting flange of our unit. Contact chatter was not monitored on the Lockheed seismic tests. However, the same switches are used in all size units and therefore any seismic test checking switch chatter would define the action of the switches in any unit. Refer to seismic test 5-6167-5 which shows the switches retained their integrity to acceleration levels of up to 89
3. 0. 8 Limitorque actuators are designed with the motor leads passing through an internal conduit in the motor mounting flange and then connected in the limit switch compartment. The length of unsupported motor leads is small (inches) thereby minimizing undue loads during seismic excitation.
Seismic tests conducted on actuators with either class B or class RH insulation would provide qualification for the.other insulation system. The seismic dwell durat'ra for the "RH" insulated motor, done during seismic aging for report 600376A, was actually longer than the generic envelope test data derived on class "B" insulation (540 secs. vs 360 secs.)

1 Sheet No. 7 LIMITORQUE CORPORATION I 4.0 Conclusion 4.0.3 The seismic tests conducted to date on manual / motor SMC/HBC or Sts/HBC actuators envelope and qualify all standard assemblies to 3g as stipulated on our Nuclear Data Summary. The additten of the seismic support plate to the assembly has been tested and the modified assembly is qualified to 6g's (see Acton Environmental Testing Corporation Report 14331). The tested combination represents the most adverse weight distribution and the sucdessful completion of the noted test can be used to qualify all modified assemblies to the 69 level. 4.0.4 The seismic test conducted to date on SMC-04 and SMB actuators qualify (- all standard units to 69's. 4.0.5 The tested combinations of the above noted actuators included the most adverse weight distribution, allowing successful test completion to generically qualify seismically all tested and non-tested units to the noted acceleration levels. 4.0.6 Thrust tests conducted prior to and following seismic aging, permitted comparisons to determine the effect of seismic aging on the Actuator. Prior to the start of the environmental qualification., the Actuator's torque switch was calibrated to provide the unit's rated torque and thrust. Subsequent to seismic aging, the actuator was mounted on a thrust tube inside the environmental chamber and the unit was stroked measuring the output thrust. Since the pre-seismic test and post seismic test thrust values were in close agreement, it is concluded that seismic aging has no detrimental effect on the Limitorque Valve Actuators. ... - ~ _ m._._
