Revised Calculational Method for Determining Changes in Transmitter Calibration 3)
EPRI Report TR-103335, Guidelines for Instrument Calibration Extension / Reduction Programs, Research Project No. 2409-21 This letter responds to the NRC's letter of February 15, 1994 (Reference 1) and provides additional information for the acceptability of our revised calculational method for determining changes in transmitter calibration frequency.
Reference 1 stated the NRC's conclusion that one aspect of our revised calculational method, as provided in Southern California Edison's (Edison's) letter of September 28, 1992 (Reference 2), is not acceptable for determining changes in transmitter calibration frequency.
The NRC Safety Evaluation Report (SER) enclosed with this letter found the new method unacceptable because Edison had collected calibration data for a maximum duration of 21 months and had not provided anj basis for extrapolation of the data to 30 months.
Edison requests the staff to reevaluate that conclusion.
Edison believes our revised calculational method is acceptable because: (A) the method utilized by Edison is consistent with the industry, (B) plant specific data provides verification for the method, (C) the values calculated by the revised method are equal to or more conservative than the manufacturer's performance values, and (D) the application of these values in the Reactor Protection System (RPS) and Engineered Safety Features Actuation System (ESFAS) setpoint calculation is very conservative.
Further, the method proposed by the NRC in Reference 1, annualization of instrument drift data, has been examined by Edison and was

Document Control Desk found to calculate drif t values which are unnecessarily conservative. A detailed explanation of points (A) through (D) above follows:
A.
The method utilized by Edison is consistent with best industry guidance.
EPRI recently issued Guidelines for Instrument Calibration Extension / Reduction Programs (Reference 3). The EPRI report found that, for the numerous instruments evaluated at several nuclear plants, these instruments did not demonstrate any significant time-dependent or age-dependent trends. The guidance in the EPRI report directly supports the methodology used by Edison for determining transmitter calibration interval changes.
B.
Plant specific data verifies Edison's method.
Edison believes the method of extrapolation used in our revised calculational method is an acceptable technique fer iiicreasing transmitter calibration intervals.
The single area where the NRC took exception to Edison's revised method is in the use of transmitter data provided in Reference 1 to justify a maximum calibration interval of 30 months.
(The data used in the Reference 1 evaluations was collected over a maximum interval of one operating cycle or about 21 months, which approaches the maximum allowed surveillance interval in effect at that time.)
The NRC felt Reference 1 did rot provide an adequate basis for the method used to extend the maximum surveillance interval from 22.5 months to 30 months.
Following receipt of the letter of February 15, 1994 (Reference 1),
Edison collected and evaluated data in addition to the data which was used as a basis for Edison's revised calculational methodology.
Data was collected from transmitter calibration records and graphed and evaluated. The resulting graphs and Edison's evaluation of these graphs are provided in Enclosure 1, Edison's Transmitter Evaluation Report.
This evaluation shows: (1) all transmitters evaluated were within the allowances established by Edison using the revised calculational method over the individual calibration intervals (typically 21 months), (2) all transmitters evaluated were within the allowances established by Edison using the revised calculational method over a 41-month period had adjustments not been made at currently required surveillance intervals, (3) three of four wide-range pressure transmitters were within allowances established by Edison using the revised calculational method for a period in excess of 60 months (the fourth had only been installed for 41 months before the last calibration), (4) all four level transmitters were within allowances established by Edison using the revised calculational method for a period of 48 months, and (5) all four temperature transmitters were within allowances established by Edison i
using the revised calculational method for a period of 45 months. These graphs clearly show the allowance established by the revised methodology bounds the changes in transmitter calibration frequency over intervals in excess of 30 months.
r Document Control Desk C.
Edison's method calculates drift allowances conservatively.
The drift allowances used by the Edison revised calculational method are more conservative than the manufacturer's performance values. That is, the drif t allowances determined by the revised method equal or exceed the instrument manufacturer's expected drift values (e.g., the revised method allowed value is 2.5% of span deviation over 30 months while the manufacturer's limiting drift value only expects the instrument to drift up to 1% of span over a 30-month period).
D.
Edison's method results in conservative application of allowances.
The allowances used in the RPS/ESFAS setpoint calculations are applied in a very conservative manner. While the results of the "As-Found"/"As-Left" analysis include errors for Measurement and Test Equipment (M&TE) and temperature effects, separate errors for multiple M&TE and temperature effects are also included in the Edison revised calculational method.
Therefore, the revised method provides additional conservative allowances.
In the February 15, 1994, letter (Reference 1) the NRC proposed annualization of instrument drift data followed by linear extrapolation as a basis for extending the transmitter data from 21 months to 30 months.
Edison examined this method during development of its revised transmitter calibration methodology and found it to be unduly conservative and technically unwarranted. provides a sketch of how the NRC proposed method compares to Edison's revised methodology.
The Edison allowance reflects the results of our methodology which includes a linear regression analysis of transmitter data. The NRC allowance illustrates how annualization of instrument drift data as a basis for linear extrapolation of the transmitter data would likely appear. As shown in the figure, the NRC allowance method would be significantly over-conservative after 12 months resulting in a significant change in setpoints which would result in a significant reduction in associated operating margins.
Application of this method would be unnecessarily conservative and would likely require: (1) new setpoint calculations from both Edison and Asea Brown Boveri - Combustion Engineering, (2) Technical Specification setpoint changes, and (3) reduced operating margins.
Based on these considerations, and items A, B, C, and D above, Edison feels that our revised methodology is sound and that annualization of instrument drift data is not warranted.
CONCLUSION:
Edison believes our revised calculational method for determining changes in transmitter calibration frequency is adequate and is in conformance with industry practices and the EPRI guidelines.
Examination of selected transmitters provides additional validation of the acceptability of Edison's revised method. Based on these factors, Edison concludes that our revised calculational method is acceptable for determining changes in transmitter calibration frequency.
Further, the method proposed by the NRC in Reference 1, annualization of instrument drift data, has been examined by
Document Control Desk Edison and determined to be unnecessarily conservative and is not technically warranted.
Edison would like to meet with you at your convenience to further discuss this issue.

SAN ONOFRE NUCLEAR GENERATING STATION UNITS 2 AND 3 TRANSMITTER EVALUATION PURPOSE The purpose of this report is to provide an additional evaluation of the revised methodology utilized by Southern California Edison (Edison) in calculating alNances for changes in transmitter calibration intervals. This revised v,ethod was used in determining the setpoints related to certain instruments replaced during the Unit 2 Cycle 6 Refueling Outage.
This report was pre to respond to concerns raised by the Nuclear Regulatory Commission (NRC) pared regarding this revised calculational method.
The background, scope, evaluation method, results, and conclusions are discussed in this report.
The attached data tables and graphs (Attachments A through D) are presented in support of Edison's revised calculational method for determining changes in transmitter calibration intervals. This information provides further validation that Edison's new method provides an adequate basis to allow extension of the maximum transmitter cai bution interval from 22.5 to 30 months.
BACKGROUND In 1989, as part of Edison's request to extend the 18-month surveillance interval for certain Plant Protection System (PPS) functions to a refueling interval, nominally 24 months, Edison performed a historical evaluation of transmitter calibration data.
This evaluation, the Instrument Drift Study (IDS), completed in 1989, was provided in summary to the NRC as part of the request for Technical Specification Amendment Numbers 88 and 78 for Units 2 and 3, respectively. The NRC issued a Safety Evaluation Report on June 8, 1990, granting Edison's request for refueling interval surveillance extension to a nominal 24 months.
Up until June 1991 the maximum allowed transmitter calibration interval was 22.5 months.
In June 1991 the Edison revised calculational method was introduced.
This revised method allowed for transmitter calibration intervals of up to 30 months. Due to the limitations of the refueling cycle interval, the actual transmitter calibration interval has been effectively 21 months since June 1991.
The IDS, completed in 1989, was the first attempt Edison is aware of to calculate allowances for transmitter drift and other effects based on experienced calibration data. Since the report was issued, however, improvements in the methods used in the IDS have been developed.
In the current draft of Recommended Practice RP67.04, the Instrument Society of America (ISA) has acknowledged the basic methods developed in the IDS with some improvements.
In addition, an alternate method has been recognized by ISA.
This alternate method was utilized as part of Proposed Technical Specification Change NPF-10/15-344 (PCN-344)) to extend the surveillance interval from monthly to quarterly for PPS bistables.
This extension was granted by the NRC and implemented " '042.
During the Sat afre Nuclear Generating Station, Unit 2 Cycle 6 refueling outage (Fall, 1991) some pressure and level transmitters which provide input 1
i signals to the PPS were replaced.
In the course of preparing this design change, it was determined that it would be necessary to update certain PPS setpoint calculations to reflect more recent transmitter qualification test
)
results.
Edison evaluated the qualification test results obtained for the replaced pressure and level transmitters and the previously used devices.
Based or, this, the historical transmitter calibration data was reevaluated to develop more appropriate allowances for transmitter drift.
A method similar to that used in PCN-344 was utilized in the revised calculational method for determining the changes in transmitter setpoints for these PPS functions (Calculations J-BBA-003, J-BBA-004 and J-ZZZ-019).
The most recent PPS setpoint calculations were performed by ABB Combustion Engineering (ABB-CE) using the more recent drift values provided by Edison. No changes were made in the safety analyses.
In addition to the transmitter replacement, in 1992 and 1993 Edison updated the Core Protection Calculator (CPC) Input Uncertainty Document, prepared by ABB-CE, to more carefully reflect the San Onofre measuring and test equipment (M&TE) rec ui rements. Calculation J-BBB-019 was issued by Edison to document the cold anc hot leg temperature transmitter drift allowances, which were used in the CPC Input Uncertainty Document.
In 1992 Edison retained a consulting firm named Tetra Engineering to perform an independtnt third-party validation of the revised Edison methodology.
Tetra is a recognized authority in statistical analyses for safety analysis and instrumentation.
Tetra issued a report in 1992 which validated the revised Edison methodology.
Edison submitted a description of the revised methodology to the NRC in a letter dated September 28, 1992, from Mr. W. C. Marsh to document the details of the revised method. An enclosure to this letter summarized the revised calculational method and differences between this method and those used in the IDS. The NRC responded to the Edison letter in a letter dated February 15, 1994.
In this letter, the NRC concluded that the revised calculational method is not acceptable for determining changes in transmitter calibration frequency.
The staff found the new method unacceptable because Edison had collected drift data for a maximum duration of 21 months and had not provided any basis for extrapolating this data to 30 months.
In addition, it was stated that the staff would accept annualization of the instrument data and use of the annualized data for instrument setpoint calculations based on the desired calibration frequency.

SCOPE The Reactor Protection System (RPS)/ Engineered Safety Features Actuation System transmitters, which are affected by the Edison revised calculational method, monitor eight plant parameters in each of the two units, as follows:

Data from the above four parameters, representing 16 transmitters (20% of the transmitter population), was collected.
This sample includes one of each make and model transmitter where the revised methodology was applied and includes a range of vendors.
The entire population of transmitters was not examined.
Based upon the range of make/model of transmitter and the diversity of parameters monitored, this sampling is representative of the transmitter population and is sufficient for the purposes of this enluation.
Data was collected for a minimum interval in excess of 30 months in order to bound the currently required calibration interval.
METHOD The "As-Found" and "As-Left" calibration history was recovered for each of the five data points (0%, 25%, 50%, 75%, and 100% of scale) for the subject transmitters.
This data was taken primarily from recent calibrations, completed since initial issue of the calculations based on the revised methodology and is included in the tables provided in Attachment 2.
To validate the calculational method for the changes in calibration over the surveillance intervals, the effects due to adjustments made during calibrations (iecalibrations) were removed from the data prior to graphing.
This was dor.e by taking the difference in the transmitter "As-Found" and "As-Left" value and adding or subtracting the difference, as applicable, from the "Value without adjustment" from the previous calibration.
Then this value was subtracted from the " Required" value and entered as a " Deviation" value in process units and % span in the tables. provides two figures where transmitter data is graphed to illustrate how this method works.
(This data is from transmitter 3PT-0101-1, 20 mA data point.)
Figure 1 shows how the transmitter data would appear if graphed with recalibrations.
Figure 2 shows the same data with the recalibrations removed.
This example shows how the graphing methodology reveals time dependent deviations. The resulting graphs in Attachments A through D represent a hypothetical situation that would reflect transmitter performance had it not been adjusted over the time period examined.
Attachments A through D provide the individual graphs for the data tables provided in Attachment 2.
Lines are drawn on each of the graphs to indicate a 30-month interval and the allowances determined by Edison's revised method over a maximum 30-month interval. Although the data is not collected at even intervals (i.e., some data is taken four months apart while some is taken 24 months apart) the data is drawn equidistant on the abscissa, with the unequal intervals indicated by the bottom scale of each graph.
Straight lines are used to connect each data point.
RESULTS For each of the channels selected, a review of the associated graphs is included in the following sections. The maximum changes identified are associated with the largest difference in the final point over the interval.

i 1.
Wide Range Pressurizer Pressure Transmitter Designation 3PT-0102, Unit 3, Channels 1, 2, 3, and 4 The wide range pressurizer pressure covers a calibrated span of 0-3000 psia and provides input to the Plant Protection System.
The transmitter for these channels is a Rosemount Model 1153GD9.
The graph for transmitter 3PT-0102-1 shows that this transmitter would have operated over the entire 65-month (over 5 years) period within the allowance predicted by Edison's calculational method. The maximum change over the 65-month interval was
.13%.
The graph for transmitter 3PT-0102-2 shows that this transmitter would have operated over the entire 65-month (over 5 years) period within the allowance predicted by Edison's calculational method. The maximum change over the 65-month interval was.13's.
Adjustments were made to this transmitter in 1990, however, these adjustments would not have been required to stay within limits over the entire 65-month interval.
The graph for transmitter 3PT-0102-3 shows that this transmitter would have operated over the entire 65-month (over 5 years) period within the allowance predicted by Edison's calculational method. The maximum change over the 65-month interval was
.19%.
Transmitter 3PT-0102-4 was replaced in 1990, in accordance with environmental qualification requirements.
The graph for transmitter 3P.T-0102-4 shows that this transmitter would have operated over the 41-month period since the new transmitter was installed, within the allowance predicted by Edison's calculational method. The maximum change over the 41-month interval was.06%.
These graphs show that all of the transmitters changed less than 10.35% of calibrated span over a minimum of 41 months, as predicted in the revised Edison methodology. Adopting the method proposed by the NRC would increase this allowance to 10.875% for 30 months or 11.87% over 66 months.
This would result in allowances which would be overly conservative.
2.
High Range Pressurizer Pressure Transmitter Designation 3PT-0101, Unit 3, Channels 1, 2, 3, and 4 The high range pressurizer pressure channels cover a calibrated span of 1500-2500 psia, and provide input to the High Pressurizer Pressure RPS trip. The transmitters for these channels are Weed Model NE-11GM. The graph in Attachment B for 3PT-0101-1 represents data points for this transmitter channel for the period from May 1988 through November 1993, a period of approximately 66 months.
In January and February,1992, 3PT-0101-2, 3, and 4 were replaced with Weed Model NE-11GM, in accordance with environmental qualification requirements. Since these three transmitters were replaced in 1992 it was necessary to go back to an earlier time period for each of the transmitters to recover larger than 30 months of data. The data points are graphed relative to percent-of-span deviation i
5 1
versus time to show how the transmitters deviate from their initial set value over the period examined.
The graph for transmitter 3PT-0101-1 shows that this transmitter would have operated over a 45-month period within the allowance predicted by Edison's calculational method. The transmitter was adjusted at each calibration interval after the first one recovered on 5-31-88.
For two of the calibration points at 4 mA and 8 mA, the transmitter exceeded the Edison al'owance of 12.5% at 66 months.
This deviation appears to be consistent with a reduction in the zero atjustment spring pressure over time. While the 3PT-0101-1 transmitter has performed within the allowances predicted by Edison's calculation method, Edison has determined that this transmitter should be replaced.
The graph for transmitter 3PT-0101-2 shows that this transmitter operated over the 55-month period within the allowance predicted by Edisoi.'s revised method. The maximum deviation over the 55 months would have been
+1.12% had adjustments not been made.
The graph for transmitter 3PT-0101-3 shows that this transmitter operated over the SS-month period within the allowance predicted by Edison's revised method.
The maximum deviation over the 55-month period would have been +1.93% had adjustments not been made.
The graph for transmitter 3PT-0101-4 shows that this transmitter operated over the 55-month period within the allowance predicted by Edison's revised method. The maximum deviation over the 55 months would have been
-0.88'5 had adjustments not been made.
In all of the above graphs, the transmitters exhibited changes over 45 months of less than 12.5% of calibrated span, as predicted by the revised Edison methodology.
Three of the four transmitters would have performed within the predicted allowance over 55 months.
These gra)hs show that the maximum change over 45 months was -2.37%.
The maximum clange over 66 months was -3.68%.
Adopting the method proposed by the NRC would increase the allowance for these transmitters to approximately 9% for 45 months and 13% for 66 months.
Again, this would result in allowances which would be overly conservative.
3.
Narrow Steam Generator Level Transmitter Designation 2LT-1113, Unit 2, Channels 1, 2, 3, and 4 The narrow range steam generator level channels have a calibrated span of 0-100% and provide input to the Plant Protection System.
The transmitters were Foxboro Model E-13DM until 1991.
In April through October,1991, these transmitters were replaced with Weed Model NE-13DMs, in accordance with environmental qualification requirements. Since the transmitters were replaced for environmental qualification requirements in 1991, to recover larger than 30 months of data, it was necessary to go back to an earlier time period for each of the transmitters.

The graph for transmitter 2LT-1113-1 show that the transmitter operated over the entire 48-month period shown in the graph within the allowance with two adjustments made during the period analyzed.
The maximum change of the five points over the 48-month period would have been
.55% had adjustments not been made.
The graph for transmitter 2LT-1113-2 shows that the transmitter operated over the entire 54-month period shown in the graph within the allowance with two adjustments made during the period analyzed.
The maximum change of the five points over the 54-month period would have been
-0.69% had adjustments not been made.
The graph for transmitter 2LT-1113-3 shows that the transmitter operated over the entire 54-month period shown ir the graph within the allowance with three adjustments made during the period analyzed. The maximum change of the five points over the 54-month period would have been
-1.25% had adjustments not been made.
The graph for transmitter 2LT-1113-4 show that the transmitter operated over the entire 50-month period shown in the graph within the allowance with adjustments made at each of the calibrations performed during the period analyzed. The maximum change of the five points over the 50-month period would have been -1.12% had adjustments not been made.
In all of the above graphs, the transmitters exhibited changes less than 14.0% of calibrated span over 30 months, as predicted by the revised Edison methodology.
These graphs show that the maximum change over 54 months was -1.25%.
Adopting the method proposed by the NRC would increase the allowance for these transmitters to approximately 16% for 50 months. Again, this would result in allowances which would be overly conservative.
4.
Narrow Range Cold leg RCS Temperature Transmitter Designation 2TT-9179, Unit 2, Channels 1, 2, 3, and 4 The nat' row range Reactor Coolant System (RCS) cold leg temperature channels have a calibrated span of 465-615 degrees Fahrenheit and provide input to the Core Protection Calculator (CPC) Departure from Nuclear Boiling Ratio (DNBR) and Linear Power Density (LPD) reactor trips.
The transmitters are Foxboro Model 2Al-P2V.
These transmitters are calibrated by performance of a string calibration which connects a test instrument to the input of the transmitter and takes readings on each of the output devices connected to the transmitter.
Therefore, these values include the effects of the entire loop or string.
The graph for transmitter 2TT-9179-1 shows that this transmitter operated over the 45-month period within the allowance predicted by t*,e tvison calculational method with an adjustment performed for new r'si.

The graph for transmitter 2TT-9179-2 shows that this transmitter operated over the 46-month period within the allowance predicted by the Edison calculational method with an adjustment performed for new RTD values on 9/18/89.
The maximum change over the 46-month period would have been J
+0.5% had adjustments not been made.
The graph for transmitter 2TT-9179-3 shows that this transmitter operated over the 46-month period within the allowance predicted by the Edison calculational method with an adjustment performed for new RYD values on 9/18/89.
The maximum change over the 46-month period would have been -
0.13% had adjustments not been made.
The graph for transmitter 2TT-9179-4 shows that this transmitter operated over the 46-month period within the allowance predicted by the Edison calculational method with an adjustment performed for new RTD values on 9/18/89.
The maximum change over the 46-month period would have been -
0.13% had adjustments not been made.
In all of the above graphs, the transmitters exhibited changes less than or equal to 10.5% of calibrated span over 30 months, as predicted by the revised Edison methodology. Adopting the method proposed by the NRC would increase the allowance for these transmitters to approximately 1.9% over 45 nonths.
Again, this would result in allowances which would be overly consarvative.
C0Ci_USIONS The transnitters selected for evaluation represent the transmitter makes and models and types of processes where Edison has applied the revised method. The following conclusions are drawn from the evaluation of this data.
1.
All of the transmitters evaluated were within the allowances established by Edison using the revised calculation method over the individual calibration interval (typically 21 months).
2 All of the transmitters evaluated were within the allowances established by Edison using the revised calculation method over 41 months had adjustments not been made at currently required surveillance intervals.
3.
Three of four wide-range pressure transmitters were within the allowances established by Edison using the revised calculation method for a period in excess of 60 months (the fourth had only been installed for 41 months before the last calibration.
4.
All four level transmitters evaluated were within the allowances established by Edison using the revised calculation method for a period of 48 months.
5.
All temperature transmitters evaluated were within the allowances established by Edison using the revised calculation method for a period of 45 months.
8
Adopting the netiiod proposed by the NRC would result in allowances which would be excessively conservative.
The data examined for this report validates that the Edison resised calculational method results in allowances which are appropriately conservative for maximum surveillance intervals of 30 months.
