{{#Wiki_filter:- _ _ _ _ _ _ _ _ - _ _ _ _ _ _ _ _ _ _ - _ _ _ _ _ l - Rescacuce 7 l NUCLEAR QUALIFICATICN TEST REPORT NUMBER 37274 r GH-BETTIS CORPORATION i HOUSTON, TEXAS This qualification test program was started in mid-year 1977 and completed January 1980. A number of revisions and additions were typically to reflect the continuously made to the test program; These changing requirements demanded by the Nuclear industry. l included additional wear aging and thermal aging as qualification requirements were upgraded. I All qualification testing was conducted at Southwest Research Institute, San Antonio, Texas and Wyle Laboratories, Huntsville, i Alabama. ~ The final results of this nuclear qualification test program show that all "N-Series" actuators manufactured by GH-Bettis.are quali-fied for use in Nuclear Power Plants and will equal or exceed the requirements of the following standards: IEEE 323-1974, Standard for Qualifying Class lE Equip-ment for Nuclear Power Generating Stations. IEEE 344-1975, Guide for Seismic Qualification of Class I (K), Electrical Equipment for Nuclear Power Generating Stations. IEEE 382 (ANSI N278.2.1, Draft 3, Rev. O, February, 1977) ~ American National Standard for Qualification of Safety Related Valve Actuators. Four (4) actuator models were chosen for type of testing. (1) N732C-SR80-12 to qualify all NHD series actuators (2) NT420B-SRl-12 to qualify all NT series actuators (except NT-5 and NT-8 series actuators, seismically) (3) NT520B-SRl-12 to qualify NT5 and NT8 series act-uators, seismically (4) NCB-520-SR80-12 to qualify all NCB series actuators. These four (4) models chosen to be the type tested units since they best represent all of the variable affecting environmental qualification as well as exhibiting the lowest natural frequencies within their series based on their respective mass , centers-of-gravity and size and also, to exhibit the hi; hest stress levels during operation.

l Page 2 ) i It should be noted that the elastomer seal materials and lubri-cants used in all actuators'in this report are generically identi-cal. Justification showing relationship between type tested and I generic model actuators is shown in Appendix A. This qualification test report'is presently made up of six (6) principle sections or volumes. It is anticipated that additional sections may be added when further testing is done to meet future qualification requirements yet to be established. A short summary of each volume is as follows: , VOLUME I, THERMAL AGING, DYNAMIC FUNCTIONAL DATA The purpose of Thermal Aging was to show that the ethylene propy-lene seals used in all "N-Series" nuclear actuators were suitable for'a qualified service life of fige (5) years. The original test parameters were established as 200 F for 200 hours at 100 percent humidity. Subsequen5 thermal aging (Volume V) of a Model NCB520-SR80-12 was performed at 250 F for 294 hours at 100 percent hgmidity. By Arrhenius Equation with continuous temperature of 120 F and an acti-vation energy of 0.8eV, this shows that the ethylene propylene seals have qualified life exp ;ctancy of 6.5 years. Since the seals of lubricants used in NHD and NT Series actuators are generically the same as used in the NCB models, they to are considered to be covered by this subsequent thermal aging" test. Based on this, elastomer
,/ n seals in all GH-Bettis "N-Series actuator must be changed every 5
( ,h years to maintain qualified. Dynamic Functional Data was also obtained, in the beginning as base-line-date, and after each phase of testing to dbtemune what effects, if any, that the various tests had on the operating capabilities of the actuators. It should be noted that throughout the test pro-gram a number of test equipment and control failures occurred in-l cluding torque transducers, solenoid valves and lbmit switches. None of these items are part of the actuators being qualified, but are pieces of equipment used to test and operate the actuators them-selves during qualification testing. (ASCO ' solenoid valves and NAMCO limit switches supplied by GH-Bettis are nuclear pre-qualified by their respective manufacturers.) NHD and NT Series actuators continued to perform throughout the test program at acceptable levels of torque output nad speeds of operation. VOLUME II, UEAR AGING, RADIATION AGING The NCB520-SR80-12 actuator was origina.p.y operated 5000 cycles with-out maintenance while the N732C-SR80-12 and NT420-SRl-12 actuators
, were operated 2005 cycles. An additional 3000 cycles were added to these same N732C-SR80-12 and NT420B-SRl-12 units (Volume VI). Based on this, all "N-Series" actuators (less seals and lubricants) are suitable for a design service life of 5000 cycles or 40 years, which- ! ever occurs first, r-(x) 7/
t I w
Page 3 8 All actuators were irradiated for a minimum total dosage of 1.4x10 rads (air equivalent) after thermal aging and wear aging with no noticable affects on operability. VOLUME III, SEISMIC TESTING Each of the type tested units were subjected to a resonant search, plant induced vibration simulation and ramdom biaxial excitation. There were no signs of cracking or yielding in the actuators and they, performed nommally during and after the tests. The Model NT520B-SR1-12 was added to the program to varify that the larger NT series actuators were suitably qualified. VOLUME IV, LOCA TESTING The Models N732C-SR80-12, NT-420B-SRl-12 and NCB520-SR80-12 act-uators were shipped from Southwest Research Institute to Wyle Laboratories for Design Basis Event (LOCA) Testing. The Model NT520-SR1-12 was not tested since the seals and lubricants are generically identical to those used in the Model NT420B-SR1-12 unit. The Model N732C-SR80-12 and NT420B-SRl-12 actuators succes-sfully outputp(assed approx.LOCA 10%).simulation with only a minor decrease in torqueThis is judged The Model NCB520-SR80-12 actuator was removed from testing after 9 hours because of excessive piston seal leakage. Post-test exami-nation showed the piston seal to be damaged. A subsequent test of (e] (_// a re-designed NCB520-SR80-12 was successfully performed at a later date (Volume V). . It should again be noted that there were several failures of torque transducers, solenoid valves and limit switches. None of these items are part of the actuator and their performance failure and replace-ment should not be construed as a failure of the actuators. ASCO solenoid valves and NAMCO lbnit switches are separately qualified for nuclear service by their respective manufacturers. VOLUME V, THERMAL AGING, WEAR AGING, RADIATION AND LOCA SIMULATION MODEL NCB520-SR80-12 A redesigned Model NCB520-SR80-12 actuator was submitted to Wyle Laboratories for Thermal Aging, Wear Aging, Radiation and LOCA Simulation. A compar.ison of post-test torque outputs with initial base line data shows no decrease in performance. Seismic testing was not re-done since the design changes in the piston seal and piston seal groove would not materially affect the seismic response of ghe actuator. With new thermal aging parameters of 294 hours at 250 F. and 100% humidity the seals in the NCB520-SR80-12 actuator are suitable for 5 year service life without maintenance (Appendix E, Arrhenius Law). Likewise, the seals in Model N732C-SR80-12 and NT420B-SR1-12 actuators are also suitable for 5 years service life
,- since they are gener,ically identical.

Page 4 VOLUME VI, 3000 ADDITIONAL WEAR AGE CYCLES - N732C'-SR80-12 AND ITT420B-SRl-12 The original Model N732C-SR80-12 and NT420B-SRl-80 actuators pre-viously wear aged, thermal aged, irradiated and seismically tested at Southwest Research Institute (Volumes I, II, III) and subj ected to LOCA simulation at Wyle Laboratories (Volume IV) were returned to Wyle Laboratories for additional wear aging of 3000 cylces. No appreciable differences in torque output was noted at the end of testing. Based on this, GH-Bettis believes all NCB, NHD and NT-Series actuators are suitable for 40 years design life (except
-seals and lubricants) and/or 5000 cycles, whichever occurs first.

QUALIFICATION OF VALVE ACTUATORS FOR NUCLEAR POWER PLANTS IN ACCORDANCE WITH SwRI TEST PLAN 02-4854-SP-1 5.0 SEISMIC QUALIFICATION ' 5.1 Test Method l 5.1.1 General j 5.1.1.1 Resonance Search , Each valve actuator was mounted on our hydraulically actuated shaker facility as it nor= ally would be in service, i.e., valve stem vertical, and a resonance frequency search was performed by inputting sinusoidal excitation uniaxially in each of the three principal axes of l the valve actuator in the frequency range from 1 - 100 Hz. Input excitation was at the level of 0.2 g's o-peak at a sweep rate of 1/3 octave or less per minute. A uniaxial accelerometer was mounted with its axis parallel to the axis l of excitation at the end of the spring cylinder as shown in photographs 5.4-1, 5.4-2 and 5.4-3 of section 5.4. During the testing of the NT4203-SRl-12, , a resonance search was performed for Y-axis excitation with a response ; accelerometer mounted on the Bettis switch. This was to determine if substantially different results would be obtained for this location of the response acceleroneter. This response accelerometer location is shown in photograph 5.4-4. Table 5.2 lists the resonant frequency search tests perfor=ed. 5.1.1.2 Plant Induced Vibration Simulation After the resonant fr.equency search,the highest frequency in the range 50-100 Hz which was not a resonant frequency was selected for each test item for each axis as the frequency for input excitation for plant induced vibration simulations. With the valve actuator mounted on our hydraulically actuated shaker table as it nor= ally would be in service, i.e. , valve stem vertical, excitation was input l uniaxially at these frequencies for an excitation level of 0.75 g's o-peak-A total of 106 vibratory cycles were applied to each test item with approximately 1/3 of these cycles in each axis. During the course of the plant induced vibration simulation tests, the actuators were operated on and off every 15 minutes and the functional parameters of pressure, torque and dis-placement were monitored as a function of time. At tha conclusion of testing for each actuator, a visual inspection was made for cracks or other signs ~ of material failure. Table 5.2 is a su==ary of the plant induced vibration simulation tests performed for each test item. Note that in the case of the , NT-420B-SR1-12 actuator a total of 106 cycles was run on the Z axis, and in the case of the NT-520B-SRl-12 actuator, the test was initially begun at J 85 Hz, then completed at 50 Hz. , i 5.1.1.3 Seismic Tests ,a
'Each actuator was mounted on our biaxial shaker i facility as it nor= ally would be in service, i.e. , valve stem vertical.
Each actuator was exposed to random biaxial excitation as defined by a required response spectrum (RRS) for the vertical and horizontal di:ections as shown in section 5.5. The actuators were excited in the vertical and i horizontal directions si=ultaneously for a period of 30 seconds for each SSE and OBE test during which time the actuator was operated through one complete a
cycle (open and closed).
) For a series of seismic qualification tests, the test item experienced five tests at the OBE level of 30 seconds a piece and one test at the SSE level for 30 seconds. The RRS leve'Is are shown in the figures of section 5.5. After a series of five OBE's and an SSE, each actuator was rotated about its vertical axis 90* and ratested with the biaxial input in this new position for five OBE's and an SSE.
I Between each test run, a visual inspection was made for any signs of cracking or matarial failure. The functional I. parameters of torque displacement and pressure were taken during the actuation I of each test item for each OBE and SSE test - This data appears in section 2.5.3. A TRS was obtained for a spectrum of damping values for each test. The figures of section 5.5 demonstrate that the TRS envelopec the RRS for these respective damping values. Table 5.2 is a summary of the seismic qualifi-cations tests performed on each test item. Photographs 5.4-5 through 5.4-9 6 of section 5.4 show the applicable coordinate system for each actuator for the applied excitation. 5.1.2 Test Equipment The test equipment to perform the resonance search, plant induced vibrations and seismic qualifications tests are shown in the following table. .Those items specifically used for these tests are indicated by an X.
- 5.1.3 calibration ,
) The instrumentation used to perform the seismic qualifications tests was calibrated in accordance with Engineering Sciences Division Nuclear Projects Operating Procedure XII-E-101-0, Calibration of Mechanical Sciences Dynamics Test Equipment. This detailed procedure is available for inspection at SwRI. All accelerometers were calibrated using a refererae standard Kistler 808K/561T which is traceable to the National Bureau of Standards. l
. l 5.2 Susmary of Tests Performed L Table 5.2 gives a summary of the tests performed for the resonant frequency search, the plant induced vibration simulation and the seismic
{ qualifications tests. 1 5.3 Results and Conclusions Table 5.2 summarizes the tests performed on the four Bettis Actuators identified in section 1.4. Table 5.3 shows the results of the resonant r frequency search and Figures 5.3-1 through 5.3-16 show the resonant frequency search plots. Section 5.5 shows the TRS's for the random excitation tests. Data for the functional values (torque displacement and pressure) obtainea during these tests is given in section 2.5.3. (See Vol. I.)
', In general the results of the seismic in-plant vibrations tests indicated that there were no signs of cracking or yielding in the test items and the test items performed normally during and after the tests.
