9 30 HONTH STABILITY SPECIFICATION FOR ROSEMOUNT MODEL 1152, 1153 AND 1154 TRESSURE TRANSMITTERS ROSEMCUNT REPORT D8900126 RETI3 ION A C 1.0 SCOPE This report documents the testing that was performed to demonstrate the new stability specification of 10.2% URL-for 30 months for Rosemount Model 1152, 1153 and.1154 transmitters. The former specification of 10.25% URL:for 6 months, including accuracy, was based on test results from the Model 1151 (Ref. 2.1). The new specification does not include accuracy.

2.0 REFERENCES

The revision level of the reference listed below were current at the time of release- of this report.

2.1 Rosemount Report 78223, Revision A. "Long. Term Test Results for Pressure Transmitters Rosemount' Model 1151." ~

3.0 TEST DESCRIPTION Test units consisted of four 1153 Series B transmitters,-

model number 1153GB6PA and serial. numbers 402720, 402721, 402722, 402723, all calibrated 0-to 100 psig. .The transmitters were powered with 34 V and output' voltage of the transmitter was neasured over a 500 ohm. resistor.

Response of the transmitter to an input pressure-of 50 pci 3 psi was recorded daily for the first week of. the test, weekly .f er the next six -months, and monthlyLfor.the duration of the test. Ambient-temperature was also recorded. Calibration checks at 20% span increments weref made between 0 and 100% span at the beginning and end of the test.

The test was criginally scheduled to run 18 months.

Input pressure was removed after 18 months and a calibration-check performed. A request was:made to extend-the test out to 30 months so another' calibration check was perf ormed prior to pressurizing the transmitters to 50 psi again. No adjustment'was made to the calibrations of the test units during the test interruption. Calibration data was recorded again af ter the test was over.

Transmitter output voltages neasured during the first 18 months of the test are shown in Table 1 along with the output shifts. Output shifts are referenced to the output voltage measured at the beginning of the test.

All of the output shifts are within the new stability st:ecificaticn of 20.2?; URL ( .016 V). Anbient

$cperaturac ranged from 70 to 82 F Results frca the extension of the test to 30 months are.

shown in Table 2. Output shifts again are referenced to

  • the cutput voltage measured at the beginning of the test.

However, the shifts are adjusted for the change in output cbserved between the last naasurerent.befora the exrension and the first measurement of the extension due '

to snut-down and start-up of pressure source.

For example, the output measured after 18 months for S/N 402720 was 5.990 V. After the pressure source was reapplied to the transmitter, the output was 5.996 V.

The output s_ift referenced to the beginning of the test is +0.006 7 (5.996 - 5.990 V). To determine the cutput shift due to drift, this value is adjusted by subtracting the 0.006 V cutput shift due to the change in pressure, resulting in an cutput drift of 0.000 V (0.006 - 0.006V).

All of the output shifts in Table 2 are within the new stability specification of 10.2% URL (i.016 V). A graph of the output drift is shown in Figura 1. .Anbient tenparature ranged frca 67-76 F.

The calibration checks made at the beginning of the test- '

are shown in Table 3 and meet the accuracy specification i0.25% span (10.020 V). Calibration checks nade after 18 ncnths are shcun in Table 4, prior to the extension'to 30 .

nonths in Table 5, and after 30.ncnths in Table 6. All naen the ceabined effects of accuracy (10.25% span) and '

drift (i0. 2 % URL) .

Subject:

Applicability of Kinemetrics' solid state instrumentation to a 30-month calibration interval.

Reference:

Request by Steve Kincaid (Philadelphia Electric) on July 7,1992 for transmittal of '

this information to you.

Dear Mr. Carolan.

The design of the Kinemetrics Model SSA-3 Strong Motion Accelerograph is in full accordance with USNRC Reg. Guide 1.12 (1974), ANSI ANS 2.2-1978 and ANSI ANS 2.2-1988.

This solid state accelerograph permits response spectra calculations and plotting to be performed on-site within minutes following an earthquake event. When integrated with the Kinemetrics Model SSP-1 Playback Computer, the EPRI CAV analysis, OBE analysis, response spectra calculations and printed plots with the earthquake response spectra vs. the plant design criteria all are executed automatically immediately following the recorded event; using spreadsheet parameters preprogrammed into the computer by plant engineem Recently (Januan 1992) the USNRC staff released Draft Regulatory Guide DG 1016 for public comment. Under this guide, the staff allows four (4) hours for detennination of exceedance of OBE criteria for sites with the ability to provide response spectra data within that time frame. Further, i i

EPRI's proposed cummulative absolute velocity (CAV) analysis, with minor modifications, is identified by the staff as an acceptable method for detennining whether or not the earthquake energy l was suffi:ient to cause damage. This is important at sites where the OBE is likely to be exceeded at higher frequencies (which are less damaging to civil structures). l The SSA-3 accelerograph does not use the Kinemetrics Model TS-3 (electmmagnetic) Seismic Trigger.

If the TS-3 Seismic Switch is required for a Level 1 OBE indicator, then the drift and secondary calibration issues addressed in my previous letter are applicable. It is my interpretation of Draft Regulatory Guide DG-1016 that plants which upgrade to the solid state instrumentation and have the ability to provide response spectra data from a sensor mounted at the containment foundation (or l freefield site if there is soil interaction at the containment foundation) will be allowed four hours for )

determinaCon of OBE exceedance. Thus, determination of OBE exceedance is based tipon analysis of i de pmvided by the instrumentation identified ir $NSI ANS/121988 as being the most authoritative;  !

the time history accelerograp't. In such case, the seismic switch need only be operated to meet j existing licensing requirements.

It is Kinemetrics' position that the design of the SSA-3 Seismic Monitoring System is capable of operating in a calibratable manner for an additional 12 months beyond the currently practiced 18 '

month calibration interval. Because the SSA-3 does not use an electromagnetic triggering device, Kinemetrics considers the SSA-3 to be superior to the SMA-3 for such applications.

Few SMA-3 systems have been sold in the last two to three years, fewer nuclear power plants going on line and customers are opting for the newer digital instrumentation. It is dierefore, inevitable that the FM cassette recording instrumentation will be obsoleted sometime in the near future. Given this condition, the following points conceming the SSA-3 will be of inten:st to you:

-The SSA-3 is seismically qualified to IEEE 344-1987.

- " " is designed to directly retrofit most Model SMA-3 FM cassette recording systems.

-All remote Kinemetrics FBA-3 sensor packages and the existine cabline directly mate to the newer solid state instrumentation.

-Each accelerograph record section has an intemal digital trigger algorithm which directly' monitors each channel out of the assigned remote accelerometer package.

Thus, use of the solid state instrumentation greatly improves the plant's post-event performance,  ;

provides higher quality data, reduces the instrumentation to be operated and, provides redundancy in .

t the triggering operation.

f I appreciate the opportunity to discuss the application of Kinemetrics' instrumentation for your project.

Please let me know if any further infomiation is required.

For the LDS (Lock Dctcction System) NUMAC the error in the performance specification is 0.7 F. This specified random value

1 g g7:1Wtl GE-EAfI' E-iIIIIPEE4 403+925GOUJ P.3 J l 1 LOG PAD MONTTOR (T/RM ) Input current fron an associated detector enters the LRM's l Fentoammeter Module where it is converted to a voltage proportional to t.he logarithm of the current. This voltage is, ' in turn, converted to a digital value by the LRM's Analog Module. The digital value is then read by the CPU Module where further , signal processing occurs. Based on testing, the process just j dcccribed contributes a drift of 1 percent of point per nonth  ! to overall instrument drift. This converts to an 18 month value ' of less than 4.3 porcent fot- the trip function.

TRIP FOINT COMPARISONS The following applies to both the LCPJi and LPJ4. 1 

  ' Trip set points are entered numerically via the instrunent's                   l front panel koyboard and display. Entered values are immediately                ;

converted from ASCII to binary format and stored in the CPU's l memory. All trip comparisons are made by the CPU using bintry l numbers. There are no drif ts accociated aith the above procans. I I l l l I l i l l l .l}}
