- RELi EF REQUEST SYSTEM: Containment Spray Low Pressure Safety Injection PUMP: Containment Spray Pumps (P-55A, P-548, P-54C)
Low Pressure Safety Injection Pumps (P-67A, P-678) CLASS: Class 2 FUNCTION: The safety-related Code pumps listed above perform a specific function in shutting down the reactor or mitigating the consequences of an accident as defined in the Palisades Plant FSAR. TEST REQUIREMENT: Pump vibration measurement acceptance criteria shall be in accordance with OMa-1988 Part 6, Table 3a .
- RELIEF REQUESTED:
CPCo requests relief from the alert limits specified in OM-6 and proposes the following vibration acceptance criteria limits for the Containment Spray and Low Pressure Safety Injection Pumps. The required action limits will be a as specified in OM-6, Table 3a for all vibration locations and channels; the limit is >.490 JPS-RMS (corrected for RMS). Alert limits will be determined as follows based on pump vibration test data collected between 1991 and mid-1995. For channels with reference values adequately below the OM-6 specified alert limit, .228 JPS-RMS (corrected for RMS) will be utilized per Table 3a. If the channel was consistently close to or above .228 JPS-RMS, the mean value plus four standard deviations will be used for the alert limit. The resulting values of the new Alert limits are listed in Attachment 2. BASIS FOR RELIEF: The Containment Spray Pumps and the Low Pressure Safety Injection Pumps are tested quarterly using flow circuits of limited capacity; no alternative
- flowpaths exist for on-line testing. As a result, the Containment Spray Pumps are tested at approximately 103 of rated capacity and the Low Pressure Safety Injection Pumps are tested at approximately 6% of rated capacity. For centrifugal pumps of this size, vibrations are considerably higher at lower
- flowrates than at normal operating flowrates due to energy dissipation, internal recirculation, and subsequent cavitation effects. These reduced pump flowrates result in higher, yet consistent, vibration levels measured during surveillance testing. Correspondence from the vendor (Ingersoll-Rand), dated 2
June 22, 1987 (Attachment 3), states that a flowrate of 1140 gpm (z35% of rated capacity) should be used for Low Pressure Safety Injection Pump testing. The letter goes on to state, however, that as the pump operated within acceptable vibration levels at the originally recommended minimum flow of 163 gpm, mechanical problems would not be expected. Due to their similar design and capacity, flowrate of the same magnitude is assumed to be required for acceptable Containment Spray Pump performance. Pump recirculation is described in detail in McGraw-Hill's "Pump Handbook," 2nd edition. Operation of centrifugal pumps at reduced flowrates and associated problems are also addressed in Igor Karassik's "Centrifugal Pump Clinic," 2~ edition. Results from two Containment Spray Pump special tests at 38% of rated capacity (2/11/91 and 4/7/92) and a Low pressure Safety Injection Pump performance test (1/19/91-1/20/91) showed all vibration levels to be below the maximum alert limit specified in OM-6. The pumps were determined to be mechanically sound and operating acceptable following the performance of these tests. These higher flow tests confirm that reduced flowrate testing causes internal
- recirculation which in turn leads to higher vibration readings. Subsequent tests for all five pumps at the reduced flowrates currently being used show vibrations in IPS-RMS that fall in the alert range as defined by OM-6.
The higher vibrations during low flow testing have been trended since May of 1991 and show no signs of increasing. Channel for channel, the vibrations are higher, but consistent with the vibrations recorded at higher flowrates. Detailed vibration signatures taken following every RMS reading do not indicate any pump degradation or problems per industry standards. Although there is significant "noise" typical of a cavitation-like disturbance, the levels across the spectrum ar low enough such that any vibration symptom would be easily identified. Additionally, the vibration signatures have acceptable IPS-Peak values which indicates that the IPS-RMS values used for trending are complex combinations of many superimposed inputs. Based on this discussion, the vibration levels at reduced flowrates are acceptable, expected, and do not prohibit useful predictive testing. However, application of the OM-6 alert limits for vibrations would inappropriately require these pumps to be regularly placed on alert and tested at double the normal test frequency, or would require significant system redesign and modification. This additional testing burden would not be warranted and would only contribute to pump degradation due to low flowrate testing. Furthermore, no benefit can be expected from this additional testing or from any system modification. Therefore, in accordance with 10CFR50.55a(a)(3)(ii), implementation of the >.325 !PS-Peak or >.228 IPS-RMS (corrected for RMS)
- alert range limit for these specific pumps represents an undue hardship without a compensating increase in quality or safety. Additionally, it is impractical to meet the vibration alert requirements because the pumps must be tested at low flowrates through mini-recirc lines due to system design.
- Ideally, three standard deviations should encompass 99.7% of all the vibration readings taken, assuming identical conditions and no degradation. Utilizing additional standard deviation prevents obvious data scatter from placing any unit on alert and causing unnecessary increased testing frequency. The 3
resulting alert levels (mean +45} were examined for the degree of vibration permitted based on industry standards. It was determined that no unit would run into the "extreme" or "very rough" range as a result of the relaxed limits. Additionally, the alert limits are adequately below the required action ranges, and will provide sufficient time to predict failure and to schedule repair. In addition to the quarterly inservice testing using the installed mini-recirculation lines, the Containment Spray Pumps will be tested at a substantial flowrate beginning in the 1997 refueling outage. The Low Pressure Safety Injection Pumps are currently tested at a substantial flowrate per Special Test Procedure T-261. These tests will be/are scheduled at nominal IO-year intervals or following pump maintenance which may result in hydraulic or mechanical performance changes not detectable by the quarterly testing method. The testing schedule will coincide with plant refueling outages. Acceptable vibration performance will be confirmed during these tests .

Ingersoll-Rand's 8X21AL Pump (L~$-~:"'l S/N A67-393/4
Dear Mr. Kupka:
In response to your 4/20/87 letter to Michael J. Banchero, we offer the following: (1) The originally recommended minimum flow of 163 GPM was
- based entirely on thermal criteriao This criteria established a flow value that would permit operation at low flows without heating the pumped liquid to a
- flas*h point. This criteria obviously results in mechanical problems (i.e. vibration related damage).
We cannot quantify operational hours versus mechanical damage. * (2) To be assured of no mechanical problems, we would recommend increasing the minimum flow to 1140 GPM for any testing and any extended periods of operation. However, if the pump operates within acceptable vibration levels while at 163 GPM, we would not expect any mechanical problems. (3) Operation at shut-off condition (zero flow) should be avoided for any length of time. Please advise if we can be of further assistance. fe.~ Richard~sniak

Palisades Low Pressure Safety Injection Pump Performance Test Internal Report Correspondence cc MCKing, Palisades WLFord, Palisades KEOsborne, Palisades RVVan Wagner. Palisades RJ Gerling, Palisades RJFrigo, Palisades TITLE T - 261 "Low Pressure Safety Injection Pumps P-67A*and P-G7B Performance Test* PURPOSE To access the performance of the Low Pressure Safety Injection Pumps after conducting major maintence on P-67 A and replacement of P-67B's motor. PRECAUTIONS This test was run with the reactor head removed and the core off loaded. Under these conditions varying shutdown ~ooling f,low was not a concern for plant safety. Therefore this test did not affect reactor safety. TEST REPORT
SUMMARY
Results of this test show that LPSI pumps exceed the FSAR design requirements. Increases in brake horsepower was seen with corresponding decreases in pump efficiency due to P-67A's impeller replacement and P-67B's motor replacement. Both purt1) and motor peak vi:>ration levels were well below plant acceptance values. The data gathered by this test will form the baseline for further pump testing. TEST RESULTS BACKGROUND T-261 was run on January 19, 1991 "C* shift (P-67A) and January 20, 1991 *A* shift (P-678). The test varies Low Pressure Safety Injection (LPSI) flow by manipulation of the motor operated LPSI "injection* vatves. Five differing flow values are used between 4500 gpm and 400 gpm. The following parameters were recorded during the test: Parameter DescriQtlgn Flow Four LPSI cold leg flow meters totaled Suction Pressure Discharge gauge of pu~ not being tested
- Discharge Pressure 1
Discharge gauge of pu~ being tested
Motor Current One phase of pump motor breaker's current
- Pump and Motor Vibration transformer Axial, Vertical, Horizontal displacement velocities of pulllJ and motor All of these parameters were recorded at each of the five flow values except for motor vibrations which were only taken at the 3000 gpm flow range and at the 400 gpm flow range.
The results of this running of T-261 were expected to deviate from past values due to the type of maintence conducted on the pumps during this outage. Outage maintence which would effect results are: P-67A 1) Installation of a larger impeller - 19 314* vs 19 318. (ref. SC-86-244)
- 2) Shatt replacement
- 3) Thrust Bearing replacement P-678 1) Pump Motor replaced The installation of a larger impeller, with replacement of the shaft, and thrust bearings was due to galling between the stuffing box bushing and the original impeller (see O-PAL-90-320 for more details). The reason for going to a larger in1)811er was to increase the margin between FSAR design flow and actual pump flow. 1t should be noted that at present P-67A and P-678 have the'same size impellers installed. P-67B's motor was replaced as an electricat preventive maintence measure. The replacement motor was originally on P-67 A before it was replaced and refurbished.
This was the second time .T-261 has been run. It was originally ran on 11/07/88. Test vakJes from 11107188 have been included for comparison. Reference values for P-67A are from the 08118186
- running of T-209 (ref. Pal. Cart. 7657, Frm. on3) and for P-678 from the 09110186 running of T-255 (ref. Pal. Cart. 7657, Frm. 0792).
DISCUSSION In order to better evaluate P-67A and P-67B's per1onnance raw and calculated data from EA-T-261
- o1(ref. att. 1) was plotted against reference values and previously run tests. Below is a brief discussion on each graph( ref. att. 5 & 6):
- 1) Differential Pressure VS. Flow These graphs are intended to show overall pufll> per1ormance and how it meets Palisade's FSAA requirements.
a) P-67A This graph shows that by increasing the in'1)eller diameter we have increased the FSAA design margin as follows: *
' At 3000 gpm FSAR design flow differential pressure (OP) is 350 ft our tested OP is now 167 psid or 385 ft. This gives a margin of 35 ft as compared to the margin of 7 ft (from the 11/07188 test) or an 80o/o increase in margin resulting in a new margin of 9%
over design. IQ At 4500 gpm FSAR maxin'l.lm flow differential pressure is 250 ft our tested OP is 123 psid or 284 ft. This gives a margin of 34 ft or 12% over maxiinJm flow DP. b) P-678 This graph shows that 01/20191 results fall within 2"o of 11/07188 values and within 1% of 2
_ reference values at the maximum data deviation point of approximately 500 gpm flow. We
- have reestablished the following FSAR design margins:
Q At 3000 gpm FSAA design flow differential pressure is 350 ft. OUr tested DP is 164 psid or 378 ft for a margin of 28 ft or 7%. 10 At 4500 gpm FSAA maxirT'llm flow differential pressure is 250 ft. our tested DP is 121 psid or 2 79 ft for a margin of 29 ft or 10%. c) Comparing P-f37A to P-678 we see that with the same size impeller in each pulil) our design and maxirT'llm flow differential pressure margins are within 20/o of each other.
- 2) Differential Pressure vs. Flow with 5% Error Bands These graphs are intended to show the precision of measured test values to reference values. (ie. repeatability of test results) a) P-67A This graph shows that even with an impeller diameter increase pump differential pressures are still within 5% of reference. Therefore while we effectively increased our margin over design we still did not significantly effect pump characteristicS.
b) P-678 This graph shows excellent precision of test results to with-in 1% of reference values. This also indicates little change in the mechanical condition of P-678 since it's reference curve was developed.
- 3) Vibration vs. Flow These graphs are intended to show pu~ vibration response with flow (also ref. att. 2 & 3) .
- a) P-67A
- This graph shows that pump vibration is lowest at design flows of 3000 gpm and highest at low flow-shut-off head conditions. All vibration levels are acceptable with the highest being PMEV at 0.17 ips. (Note: 0.30 ips is considered the accept~ limit in the Palisades pu~ program.)
b) P-678 This graph also stiows that pump vibration is lowest at design Hows of 3000 !J:lm and highest at low flow shut-off head conditions. All vbratlon levels are acceptable with the highest being PMEV & PMEH at 0.135 ips. (Note: 0.30 ips is considered the acceptable limit in the Palisades purfl> program.) c) Motor Vibration Motor vibration versus flow was not graphed since the peak vakJes did not exceed O.1 ips. However general trends of increased vibration with increased flow and P-678's values being nearly double that of P-67 A's can be seen from the raw data.
- 4) Brak* Horsepower vs Flow These graphs are intended to shOw the power input of the pump's motors needed to deliver the measured flow rates.
a) P-67A This graph shows an overall increase in horsepower over reference vakJes. However previous reference values and test data were taken with a smaller ~lier and therefore higher values would be expected. It should be noted that motor fuH load amps are 92 and
- 3
amp readings at 4335 gpm are 90. Therefore the motor is still capable of delivering enough power to support pump maximum flow requirements .
- b) P-678 This graph also shows an overall increase in Brake Horsepower over reference. values.
This.increase is due to the replacement of P-67B's motor with a refurbished motor. Motor current draw at 4340 gpm was 93 afll)s which is slightly abOve the fuU k>ad amp rating of 92 amps. However, this is not a concern since we are approaching the maxim.Jm pu~ flow design rating of 4500 gpm and are still well with-in the service factor of the motor which is 1. 15 of full load amps or 105.8 al'f1)s. Note design flow of 3000 gpm which is also shutdown cooling flow produces amp readings of 84 amps which is well below the full load amp rating of the motor.
- 5) Brake Horsepower vs Flow with 10% Error Band These graphs are intended to show the magnitude in changes of brake horsepower ar.d the
- precision of collected data to reference data.
a) P-67A This graph shows that even with an increase in impeller diameter brake horsepower is still within 10% of reference brake horsepower values. b) P-678 This graph shows that brake horsepower has increased greater that 10% above reference values. As previously mentioned this is attributed to replacement of P-67B's motor. c) The brake horsepower data shows some scatter and therefore a sensitivity test to its dependence on measured amps will be done. From EA*T-261-01 sh 4(ref. att. 1): P-67 A
- BHP
- 4.34A P-678
- BHP
- 4.48A Actual test readings of amps are multiplled by 30 therefore the equations become:
P-67A
- BHP* 130.2A (read)
P-678
- BHP* 134.4A (read)
Test readings were taken to the 0.1 (terth of an amp) a deviation of 0.1 amp would result in a deviation of 13 bhp which would be 511/o of measured bhp at the lowest flow condition and 3% of measured bhp at the highest flow condition. With a meter accuracy of
+I* 0.1 afl1).s differences in measured values from true values could cause up to a 5%
error in bhp. Also the test requires current measurement of only one phase, if all three phases were read and an average taken a more accurate bhp figure could be derived. Based on this information a contributing cause to high brake horsepower values could also be attributed to instrument error.
- 6) Pump Efficiency vs F1ow with 5% Error Band These graphs are Intended to show changes in pump efflcJency with flow and the precision of collectld data to reference data.
a) P4J7A This graph shows P-67A to be most efficient at its design flow of 3000 gprn*. It also shows that even with an increase in impeller diameter pump effldency did not deviate from reference by more than 5%. b) P-678 . This graph shows P-678's efficiency to. have dropped by more than 5% from reference
- 4
-_: values. This is directly attributed to the increase in bhp resulting from the replacement of
- P-678's motor. It also shows its greatest efficiency point is at its design flow of 3000 gpm .
Instrument error can effect test results as seen above. What follows is a brief description of the error which could be induced by instrumentation used in this procedure: i) Pressure Gauges Suction and discharge pressure gauges were pre and post-test calibrated. The discharge pressure gauge did not deviate from calibrated values. The suction pressure gauge was out of calibration by as high as 0.1 psi in the test data measured range and 0.4 psi in the range not used by the test. Since test values for psig are plotted to the nearest 1.0 psig a 0.1 psi deviation from calibration will not significantly effect the results of this test.
- 2) Ammeter Discussed in previous section.
- 3) Flow Meters _
The flow meters used in this test had an aca.iracy of +I* .05% which would be a ~axim.Jm deviation of .002 volts. Since readings were taken to the second decimal place only (ie. 2.41 volts) this error will not effect test data. CONCLUSION Test results shOw we have successfully increased the performance of our purf1>S with the installation of larger irfl)ellers. A larger margin between pump operation and F$AR design requirements now Unfortunately a larger i"1)eller (P-67A) and replacement motors (P-678) decreased our pump efficiency especially at low flow values. This is not a concern since pumps operate at low flow conditions for short test periods only. Results of this testing will form the baseline data for further pump testing to track pomp degradation. Recommendations Due to the large effects small variations in measured ament have on test results it is appropriate to revise T-261 to record current readings on all three phases and then average the results to calculate brake horsepower.

Subject:
P-54's Vibration Status CC: RP Margol TC Saarela AAA 91*012 The latest set of Q0-10 Surveillance Testing on P-54's taken on February 11, showed four vibration measurements in the surveillance's alert category. Two were on the pump horizontal and vertical of P-54A, and two were on the motor inboard and outboard axial of P-54C. There are several potential causes for the values being in alert status. First, this was the initial set of data obtained using the new DLI Watchman vibration data collector system. With a different instrument and ac_celerometers some variation is likely. Second, this was the first set of data taken in velocity RMS readings. Previous limits had been set in mils based on use of a TK-80 vibration meter. These limits were revised based on a theoretical conversion of mils to velocity, a*ssuming a simple vibration signal. If there are significant amplitudes at frequencies other than runnioo speed, a complex s igna 1 results, causing some inaccuracies in this conversion. A third potential cause for some of the changes could* have been the change in location .of the readings. This occurred as a result of the use of a single point triaxial ~ccelerometer in the DLI system. Finally, maintenance was performed on P-54A and P-54C since the last Qo-10. on P-54A, a new impeller, shaft, and bearings were installed and the unit was realigned. P-54C was also realigned. Any of the above changes could cause normal variations in vibration level. With all of these combined occurring, there was a high probability of variations. Even though vibration values were in the surveillance alert range, data gathered on February 11 during Q0-10 Surveillance testing, indicates* that the P-54's appear to be mechanically sound. The largest overall velocity reading was .21 inches per second rms (.3 ips peak) on P-54B (See Attachment 1). This is an acceptable valuable .per industry standards. The vibratiop signatures on P-54A (See Attachment 2) indicate primarily a normal impeller vane pass frequency. Vibration values on P-54C moto~ (See Attachment 1) are somewhat higher than the other two motors, a.s was the case in previous QO- 16 tests. A small amount of motor *looseness was indicated by signatures (See Attachment 2) . This was also seen in previous Q0-16 tests and when the motor was testeq uncoupled on 12-14-90. This does not appear to be a serious nor escalating problem
- at this time. *
-. Based on the:a- above, it is recommended that a new vibration baseline be established for P-54' s for Q0-10 using the February 11 data. In addition a new baseline should also be established for the next Q0-16 test using the rms velocity readings taken during the next test. No need is seen for increased surveillance testing of these pumps at this time
