LONG TERM ACTION PLAN A.

Introduction In our response to I.E. Bulletin No. 86-02 (Ref. 5) we described the corrective actions that were to be taken prior to startup of the units and the actions that were to be taken in the near future following startup.

Prior to startup of each unit the setpoints of the SOR differential pressure switches were revised per the criteria established in the setpoint characterization tests, and the calibration procedures were revised regarding the method of obtaining setpoint readings and to include action and reject limits.

The ECCS minimum flow switches were tested during actual system operation, and reactor water level drop tests were performed to verify the new level 3 switch setpoints at atmospheric and normal reactor pressure.

After startup a quarterly calibration frequency was established for these switches.

In addition an evaluation of alternative level sensing instruments has been completed.

In addition, a commitment was made to adjust the surveillance intervals based on the switch calibration data and to perform reactor water level drop tests during shutdown of each unit for the next refueling outage.

The adjustable surveillance interval will help ensure that the switch setpoints remain within the acceptable range.

The level drop tests that will be performed at the end of the cycle will demonstrate the stability of the switch setpoints both at a atmospheric and operating pressure.

Since the calibration procedures and surveillance requirements have been revised,'the LaSalle units have operated for three to four months and a large amount of data has been obtained.

We have reviewed the performance of the SOR DP switches to date, and this evaluation is contained in Attachment B of this submittal.

Based on an evaluation of the SOR switches and alternative level instruments, we have developed a long term action plan concerning design changes and surveillance requirements.

Table A-1 summarizes the actions that will be taken and their scheduled completion dates.

B.

Design Changes i

Based on a detailed evaluation of the performance of the SOR switches and alternative level instruments, we have concluded that the SOR DP switches will reliably perform their safety function at the new setpoints based on the setpoint characterization tests with a monthly calibration frequency for the level 3 switches and a quarterly calibration frequency for the o'.her switches.

We have also determined that replacing the reactor water level switches with an analog trip system would improve plant availability and provide substantial economic benefits to the company.

These include a reduction in inadvertent scrams, ESF actuations, and surveillance labor requirements.

These benefits result from reduced valving operations during the functional tests, and a substantial increase in the margin between the operating range and the trip setpoints.

For these reasons the decision was made to implement this design change, and the necessary funds have been requested and authorized for this project.

Modifying the reactor water level instrumentation channels to a

replace the existing level switches with an analog trip system will involve substantial changes to the plant.

Therefore, engineering must proceed carefully with the design to ensure that all applicable codes, standards, regulatory requirements, etc. are being met and that the design changes will not result in unreviewed safety questions or installation errors.

The minimum time period required to develop the installation drawings and obtain the equipment is 12 to 15 months for the RPS instrumentation and about 30 months for the ESF and RCIC instrumentation.

Modifying the ESF and RCIC instrument channels will require more time because new cabinets are needed for the additional trip units, relays, etc.; while the trip units and relays required for the RPS instrument channels can be installed in existing cabinets.

Installation of the design change will be completed during the first refueling outage following this design phase.

Table A-1 lists the scheduled completion dates for implementing these design changes for the RPS and ESF/RCIC instrumentation channels for each unit.

During the next refueling outage for each unit, the input to the reactor water level instrumentation channels that initiate isolation of the main steam line valves will be changed from SOR DP switches to electronic trip units connected to Rosemount transmitters as part of the ATWS modification.

The work on Unit 2 for this modification has already started.

However, the SOR level switches that currently perform this function will not be deleted by this change because these switches will still be needed to initiate closure of other containment isolation valve groups.

During the next refueling outage for Unit 2, the one SOR level 8 switch will be replaced with a Barton model 288A switch.

Upon completion of this modification, all of the level 8 sensors on both units will be Barton switches.

These switches will also be replaced with an analog trip switch at the same time the other ESF and RCIC switches are replaced for the same economic reasons discussed above.

No design changes are being considered for the other SOR DP switches such as the main steam line high flow, line break detection, and ECCS minimum flow switches.

Replacing these switches with an analog Ltip system would teduce surveillance labor requirements but would not reduce the number of inadvertent scrams or ESF actuations.

Therefore, replacing these switches will not improve plant availability.

Sufficient margin exists between the operating limits and the trip setpoints for these switches, and surveillance testing on these switches is highly unlikely to cause a scram or ESF actuation.

In addition, esperience has shown that the existing surveillances are adequate to detect switch failures or degradations.

C.

Surveillance Requirements To ensure that the switches continue to perform reliably and satisfactorily and that failures are detected quickly, the calibration frequency for the level 3 switches will be increased to monthly.

That is, each of these switches will be calibrated at least once a month.

For the other SOR DP switches the calibration frequency can vary from monthly to quarterly depending on the performance history of the switches.

The maximum interval between calibration will be three months.

The SOR DP switches in each unit are divided into 16 groups.

The selection criteria was based on safety function, instrument location, and/or calibration procedures.

If the measured setpoint of a switch exceeds the action limit, the calibration period for all of the switches in the associated group will be reduced by one month.

If the setpoint of this switch exceeds the action limit at the next calibration, it will be replaced as described in the next paragraph.

If the setpoint of another switch in this group exceeds the action limit at the next calibration, the calibration period for this group will be further reduced.

Continued poor performance of the switches in this group will result in further reductions of the calibration period until the switches are calibrated monthly.

Increases in the calibration interval for a switch group will not be allowed unless all of the switches in the group perform satisfactorily during a calibration or the troublesome switches are replaced.

The calibration interval will be increased in one month steps only, and the calibration interval will not be increased beyond three months.

If the setpoint of a switch exceeds the action limit during two consecutive calibrations, it will be scheduled for replacement within 14 days.

If the setpoint of a switch exceeds the rejection limit, the associated instrument channel shall be declared inoperable until the switch is replaced, and action will be taken in accordance with the applicable Technical Specification.

This switch will also be disassembled and inspected, and the inspection results will be sent to the NRC in a docketed formal transmittal.

Table A-1 describes in more detail the new surveillance requirement.-

and lists the switch groups.

D.

Revisions to the Technical Specifications Technical Specification changes are being considered for the level 3,

level 8, and main steam line high flow applications because recent analysis has shown that the existing allowable values and setpoints are very conservative with respect to the actual safety limits determined by G.E.

Therefore, these values can be changed without affecting the safety of the plant.

Although the level 3 and 8 switches are being replaced with an analog trip system, a revision to the Technical Specifications is being considered for these applications to increase the margin between normal reactor water level and the trip setpoint.

If a revision to the Technical Specification is requested for these two applications, the new allowable and setpoint valves will be based on the analytical limits determined in the General Electric study, and calculations will be submitted that will verify the adequacy of the new values.

r,

l Since the main steam line high flow switches are not being considered for replacement, revisions to the Technical j

Specifications for this application are being examined to allow the plant to operate at rated power.

To allow for static shift, repeatability, and' drift, these switches had to be set to trip between 85 and 96 psid to ensure that the switch setpoints do not exceed the allowable value of 116 psid during plant operation.

The plant can only operate at approximately 91% to 94% of full power with these setpoints.

A G.E.

analysis shows that the analytical limit for this application can be increased from 123 to 178 psid without increasing the consequences of a main steam line break.

If a technical specification change is requested, calculations will be submitted to verify the adequacy of the revised allowable and setpoint values based on the General Electric analysis.

JUSTIFICATION FOR CONTINUED USE OF STATIC-O-RING DIFFERENTIAL PRESSURE SWITCHES l

IN SAFETY APPLICATIONS I.

Executive Summary The June 1, 1986 feedwater transient event at LaSalle Unit 2, in which three out of four reactor scram level switches actuated below at their anticipated trip points, prompted a detailed study of the behavior of the switch's performance under elevated and zero static pressure conditions.

Details of the study and results of the supporting system operational tests were presented to the NRC in several submittals and meetings.

(See references.) As a result of the studies and tests, several changes were implemented in the operations and maintenance of all of the SOR series 102 and 103 differential pressure switches in applications important to safety.

LaSalle now has accumulated a considerable amount of operating and maintenance experience with the SOR switches currently in service since the completion of the LaSalle SOR Setpoint Characterization Test Program in July, 1986 for Unit 2,

and in September, 1986 for Unit 1.

In the test program, it was learned how the differential pressure switches behave when subjected to elevated static pressures in service, and the switches' setpoints were adjusted accordingly to take into account the effects observed in the testing.

Since restart of the units, satisfactory operating experience coupled with the data received from the manufacturer's long-term test program, provide assurances that the plant can operate in a safe manner:

+ Calibration data taken on appropriately chosen surveillance intervals show the switches to be performing within the parameters found in the studies and testing programs.

Switches with drift and repeatability characteristics that exceed pre-defined limits are readily identified and replaced, when necessary.

Since implementation of the new screening criteria for surveillances, only two switches have been replaced.

PAGE 1 i

LASALLE COUNTY STATION--UNITS 1 & 2 I.

Executive Summary (continued)

+ The failure of a switch is detected quite readily with the revised surveillance intervals, and since the startup of the units following the testing program, only one switch has failed.

The shortened surveillance intervals result in an overall improvement in system reliability.

+ A comprehensive disassembly and inspection of 15 Unit 1, Unit 2, and spare switches does not support the theory that a suspected common mode leakage problem with this style of switch exists.

This inspection included a leakage test using highly sensitive test equipment.

+ Successful demonstration of safety performance through system performance tests under various pressure conditions (reactor level drop tests and ECCS minimum flow loop tests) has verif'.ad that the settings chosen 8

for the switches are within and conservative to the existing technical specification allowable values.

These settings include greater margins from the analytical limits than had existed prior to the June 1 event.

+ Repeat performances of the reactor watar level drop tests at the next shutdown of each unit are expected to yield the same successful results since the calibration history data for the switches has provided information which was used to select or verify appropriate surveillance intervals.

+ Additionally, LaSalle's maintenance personnel have been familiarized with requirements for observation of the switch performance behavior during surveillances so that they can more readily identify switches which exceed pre-defined limits or those which require an unusually large number of adjustme*1ts to achieve a stable trip j

setting.

+ Operating personnel have been familiarized with how potential switch behavior may affect system operation.

Commonwealth Edison Company has concluded that continued operation of LaSalle Units 1 & 2 with SOR differential pressure switches in various safety functions is justified.

l This is based on the continued performance of these devices within the bounds determined by the comprehensive setpoint PAGE 2

LASALLE COUNTY STATION--UNITS 1 & 2 I.

Executive Summary (continued) testing program performed at LaSalle and at SOR, Inc.

Recently studies were completed to evaluate the feasibility, costs, and benefits to be gained in the use of alternative reactor water level sensing instrumentation.

Those studies showed that the use of analog transmitter / trip systems would provide improvements in reactor water level trip channels that would result in a more economic operation of the units.

Based on these studies, plans are now underway to implement modifications to take advantage of these improvements.

i Additionally, evaluations of the existing technical specification requirements for many of the applications now served by SOR differential pressure switches have been conducted.

These evaluations have concluded that in some cases, the existing technical specification allowable values are overly conservative, and more appropriate values, supported by calculations, would provide additional operating margin without compromising safety.

The option to take advantage of these more appropriate allowable values is now being considered.

There is presently sufficient evidence, however, to show that the continued use of SOR Differential Pressure switches with their revised calibration and maintenance procedures will satisfy the safety function requirements of the applications served by these switches.

The balance of this document provides technical data and operating performance summaries.

This data supports the conclusion that continumi operations of Lasalle with SOR l

differential pressure switches is justified.

LASALLE COUNTY STATION--UNITS 1 & 2 II.

Calibration History Since Restart of the Units Since restart, both units of LaSalle have experienced satisfactory surveillance results for the SOR differential pressure switches in all applications.

In the September 8, 1986 response to the IE Bulletin 86-02 it was stated (Table 4

--Corrective Actions, Item 6) that the switches in all applications would undergo surveillances starting with a short (as low as two weeks) interval and increasing to no longer than a three month interval.

To date, about one-fourth of the switches have now undergone a full three-month surveillance interval.

Most switches have yielded data taken after about two months of undisturbed operation.

The data shows that since restart of the units, one switch has exceeded its pre-defined action limit, one switch has exceeded its pre-defined screening criteria for rejection, and one switch was detected to have failed completely.

The surveillance interval for the group of switches serving the same application as the rejected switch has been reduced to the duration of the previous successful surveillance, (in this case, one-month) per the program outlined in the response to IE Bulletin 86-02.

An evaluation was made of the calibration data for the group of switches performing the same application as the rejected switch.

The application is Reactor Water Level 3--ADS Permissive function, which has reject limits of +/-2.9 "W.C.

This application is served by SOR model 103AS-B212 series switches, with an adjustable range of 7 -100" W.C.

This is the same model being tested in the SOR, Inc.

long-term test program (see section VII), so a comparison was also made with the long-term test data.

It was observed that the average " indicated" drift rate of the switches in the SOR long-term test is about 1.6" W.C.

when left undisturbed for a period of three months (See Appendix B.)

However, the average " indicated" drift of the non-rejected switches at LaSalle is about 1.6 "W.C.

over a period of two months.

It is believed that the reason for this disparity is that the SOR, Inc. test data provides a better indication of true instrument drift after the initial pressure soak period because all data is being taken at elevated static pressure under controlled conditions without the effects of disturbing the switch when reducing the elevated static pressure to atmospheric pressure to take j

readings.

The SOR data contains elements of instrument drift plus repeatability while the LaSalle calibration data PAGE 4 I

i LASALLE COUNTY STATION--UNITS 1 & 2 II.

Calibration History Since Restart of the Units (continued) contains elements of drift, repeatability, and the effects of switch disturbances, such as the depressurization of the switch to take calibration readings.

Thus the LaSalle calibration method yields results that lead to the taking of actions that are more conservative than necessary, however, it is difficult to separately quantify the effects of true instrument drift or pure static shift.

In any case, to ensure that the trip points are within the reject limits (defined as the sum of the repeatability [+/-

1.86 "W.C.] and technical specification drift value (1.05 "W.C.] margins) the surveillance interval for the Level 3 scram and ADS permissive functions has been reduced to a maximum of one-month.

A review of the calibration data for the other switch applications has also been conducted.

Based on satisfactory performance thus far of switches in the other applications, it has been decided to continue with the quarterly maximum surveillance intervals for the other applications.

Among these other non-Level 3 applications, since' restart of the units, only one switch has exceeded an action limit, and only one switch has failed.

This failure was found during a monthly functional test of the switch.

Appendix A contains a summary of all the instrument setpoint variances exhibited from July 30, 1986 through December 10, 1986.

This data is presented as differences between the previous "As-Left" and subsequent "As-Found" trip points for the switches in each group performing safety functions.

The action and reject limit screening criteria appropriate to the group are also presented.

The data is presented as values found in each progressively increasing calibration interval used for that particular group.

Data is rounded up to the nearest 0.1 "W.C.

or 0.1 PSID.

Minimal Number of Failures At LaSalle, there are a total of 117 applications making use of SOR series 102 and 103 differential pressure switches.

1 These switches have been in service dating back in some cases to the fourth quarter of 1984.

Since restart of the LaSalle units following the setpoint characterization testing program approximately 44 switch-years of operating experience have been accumulated (59 switches 9 five months on Unit 2 and 58 switches 9 four months on Unit 1.)

During this time, only one switch has failed.

(Switch Tag No.

2E31-N013BB)

Prior to restart of the units, five other switch failures, in approximately 150 switch-years of operation have occurred.

These five include one switch which was found to have a rusted bearing (switch tag no. 2B21-NO38B--see " Report of Investigation of Static "O" Ring Differential Pressure Switches--LaSalle County Station," dated August 1, 1986), one switch which was found to have loose bolting required to hold the two halves of the body together and was subsequently found to have tiny holes in its diaphragm (switch tag no.

1E12-N010CB), and three switches which exhibited slow leakage from high pressure-side to low pressure-side, which is indicative of diaphragm failure (switch tag nos. 1E12-N010CA, 1E12-N010CA replacement #1, and 2B21-NO38A.)

The 2B21-NO38B failure was caused by an excessive amount of corrosion in one of the cross-shaft bearings of the switch, thus inhibiting the rotation of the shaft required to displace the microswitch plunger to change the contact status.

When this failure was discovered, it was postulated that there could be a potential for leakage along the shaft allowing water to sit in the bearings and induce corrosion.

I However, to date this failure has not proven to be considered a common mode failure for SOk switches.

(See Section IV.)

The 2E31-N013BB failure appears to have resulted from a small tear in the diaphragm, which prevented the establishment of differential pressure across the switch.

The discovery of this failure was made during a monthly functional test of the 1

switch, and failures of this type are readily discovered.

i The three other switches with apparent diaphragm failures were also found during either functional, calibration, or pressure cycling tests.

They were discovered as long ago as September, 1985, prior to the preparation of a formal disassembly and inspection procedure.

Minimal Number of Failures (continued)

The differential pressure sensing components of d.p.

instruments have historically been susceptible to causing j

degraded performance or complete failures of the instrument, whether they are diaphragus, bellows, or capacitance or strain gauge cells.

The failure rate for SOR switches compares favorably with failure rates of other manufacturer's

}

instruments.

A review of LaSalle's SOR failure experience (six failures in approximately 194 switch-years) with its l

}

large data base of switches, and a search of NPRDS failure data base for Rosemount transmittors reveals, for example, failure rates of comparable order's of magnitude.

Recently a switch (2B21-NO38A replacement) was found to have exceeded its pre-defined screening criteria for rejection by a small amount.

Exceeding the switch reject screening criteria is not considered to be a failure of the device.

The criteria for establishing this rejection was based on the sum of the published technical specification value for i

)

instrument drift and the margin allocation for switch trip point repeatability.

i l

Experience has shown that the station's procedure of performing calibrations by first reducing the static 1

pressure to atmospheric and then applying a test pressure to one side of the device while venting the other side results in obtaining readings that are higher than the readings that are taken at the same interval on-1 the SOR Long-Term test program (See Section VII.) in i

which trip values are measured with the full static j

pressure applied to the switch.

It is believed that the i

effect of disturbing the switch to c librate it results in actions being taken that are more conservative than j

those which would be required had the switch been calibrated at pressure as in the SOR Long-Term Program.

I This switch was subsequently disassembled and inspected at

}

the SOR, Inc. factory.

A burr was found on the adjusting screw.

The presence of a burr in this location can cause j

difficulty in obtaining a stable trip setting during calibration of the switch.

It is possible that this could

-l have contributed to the result of the switch being found j

outside of its reject screening criteria.

Minimal Number of Failures (continued)

In any case, the switch was screened by the limits established in the characterization test program, and this has the result of improving the overall performance of the population of switches serving the function.

t 1

Some switches have been replaced in '.he past as a j

precautionary step due to the observance of unusual or erratic microswitch behavior.

Switches 2B21-N024A, 2B21-4 NO24B, and 2B21-NO37AA fall into this category.

All three of j

these switches would have performed adequately in service, however they were replaced with switches with better i

performance microswitches.

These were not considered as

failures.

Disassembly and Inspection Results i

j Upon discovery of corroded bearings in one of the 117 installed switches (2B21-NO388--see Section III) it was i

I hypothesized that a potential common mode problem among all SOR differential pressure switches could be O-ring leakage.

i A comprehensive program was undertaken to determine if leakage paths existed in switches which were poor performers in the LaSalle SOR Setpoint Characterization Testing, the manufacturer's factory testing, or in the calibration or j

functional surveillances.

i In addition to the five Unit 2 switches which were

]

disassembled and inspected as described in the report 1

dated August 1, 1986, eight Unit 1 and spara switches were i

similarly disassembled and inspected.

These eight switches j

were those whose performance exceeded the-criteria l

established for maximum acceptable static shift, repeatability, or drift allowances. They included five model B212 series switches (7" - 100" W.C. adjustable range) and three model B203 series switches (20" - 200" W. c. adjustable range.)

Four of these switches had exhibited excessive static shift performance, three switches had exhibited excessive repeatability performance, and one switch exhibited-a large shift in setpoint over a relatively short period of

{

time.

Two of these switches had been in service for more j

than one year, and thus had been pressurized with 1000 psig reactor water.

Four others had been installed and exposed to

[

water in the instrument piping system, but had not yet been pressurized.

Two of the switches had been spares and had never seen any service.

Also, two switches that have been in service on. Unit 2 since the re-start of the unit in August have also been disassembled and inspected.

One of these (2B21-NO38A l

Replacement) had exceeded its reject criteria on a j

calibration surveillance, and the other switch (2E31-N013BB) i failed to trip during a functional test because no differential pressure could be established across it.

(See j

Table IV.1 Summary of Inspections.)

Prior to disassembly, the switches were subjected to a witnessed halogen leak test at 1000 psig.

The halogen leak i

i detector (Inficon HLD 3000) was calibrated for a leak rate of f

0.1 ounce / year using 96% nitrogen and 4% Freon 12.

No cross j

shaft o-rings exhibited any measurable leakage.

Upon disassembly and inspection it was found that no rust was I

LASALLE COUNTY STATION--UNITS 1 & 2 IV.

Disassembly and Inspection Results (continued) found in any of the bearings and no moisture was evident in any of the microswitch or spring housings.

The internal components were measured and no parts were found to be out of tolerance.

There was evidence of the same brown foreign substance on the cross shaft and static (but not dynamic) o-rings of those switches that had been exposed to water in the instrument piping as was reported in the August 1, 1986 report, but these deposits could not be shown to have any adverse influence on the performance of the switch.

Some switches were found to have machining burrs on their adjustment screws, which has the effect of causing difficulty in setting of the trip point, and sometimes results in finding the switch at a slightly different setpoint than desired.

As a result of finding these burrs, SOR, Inc. has implemented a 200% inspection requirement for this anomaly in the manufacturing process for new switches.

The fact that no moisture was evident or no corrosion was found in any of the bearings of the inspected switches has shown that the rusted bearing found in the ADS Permissive switch of Unit 2 does not appear to be a common mode problem among SOR differential pressure switches.

One of the disassembled switches had been too contaminated to be sent to SOR, Inc. for inspection.

Instead, it was i

inspected on site.

This switch, a replacement for one that was rejected because of unusual calibration and static pressure behavior, had exhibited inability to maintain a differential pressure across its diaphragm.

Upon disassembly it was noted that the bolts holding the two halves of the a

body together were not torqued as tightly as they should be, which could allow the diaphragm 0-rings to not maintain their sealing function.

In any case, no further evidence of rust or corrosion of bearings preventing shaft rotation has been observed.

The one rusted bearing that had previously been found had only been discovered after a period of one year had elapsed since the device was last calibrated.

Since the discovery, the surveillance interval for SOR differential pressure switches was shortened to a maximum of three months.

It is highly i

likely that the onset of inhibitors to shaft rotation will be detected early enough with this increased calibration frequency to allow timely actions for system reliability assurance.

Successful Demonstration of Safety Function Performance As commitments made in the responses to the IE Bulletin 86-02 and to the NRC's June 2, series of reactor level drop tests were performed to1986 Confirmatory Action Lett demonstrate reliability of safety function served by the level 3 scram SOR differential pressure switches.

tests were conducted at both shutdown and operating pressure These conditions of the reactor vessel.

of test was to demonstrate that the static shift andThe purpose of this type repeatability effects observed in the LaSalle SOR Setpoint Characterization Testing Program were appropriately taken into account in the establishment of revised setpoints for the switches.

The tests demonstrated reliability of safety function served by the switches and that the setpoints chosen have provided for proper operation of the scram switches within the allowable range of values established in the LaSalle Technical Specifications.

Repeat performances of these tests are planned to be conducted at the shutdown of each unit for the next refueling outage.

This will demonstrate that the switches can maintain their appropriate settings, and that reliability of the switches for safety system performance is achievable over long periods of time.

Benefits of Augmented Surveillance Schedule Since the restart of each unit, all SOR differential pressure switches have undergone an augmented surveillance schedule.

Details of this increased frequency schedule are contained in the response to IE Bulletin 86-02, dated September 8, 1986.

This augmented surveillance serves to assure that the amount of instrument drift allowed between successive calibrations is minimized and is consistent with the switch settings and technical specifications.

It also provides for a more timely detection of incipient degradation, and prompt detection of switches that have failed completely.

An additional benefit gained through both the new surveillance schedule and the performance of the LaSalle Setpoint Characterization Test Program has been an increasing familiarization of plant personnel with the behavior of the SOR differential pressure switches.

This familiarization, coupled with continuing periodic observations of trends in calibration data from bach switch provides for a better ability for immediate detection of switches exceeding pre-defined limits or exhibiting difficulty in setting the trip point.

Long Term Test Program l

SOR, Inc. has been conducting a long term test program in i

conjunction with the LaSalle ongoing operating experience j

with the switches.

The long term test consists of the continuous pressurization (1000 psig) of twenty calibrated i

Model B212 differential pressure switches similar to those in l

service at LaSalle in the Level 3 scram and ADS Permissive

{

functions.

The switches are cycled periodically to determine i

the amount of drift exhibited since the last exercise of the

{

switch.

Originally, the switches were exercised in groups such that one group was to be exercised daily, one group was to be exercised every two weeks, one group was to be exercised every four weeks, and one group was to be exercised i

i avery six weeks.

(On the graphs on the following pages, j

these are identified with the prefix "D" for the originally-cycled Daily switches, "2" for the two-week, "4" for the four-week, and "6" for the six-week switches.)

Currently, however, all switches are being exercised at approximately one month intervals.

This program provides a better indication of true instrument drift exhibited by this model 3

j of switch than the plant calibration data because it reveals l

trip values resultant from only drift and repeatability, whereas the plant data includes some effects from disturbing

{

the switch by reducing the pressure from operating to j

atmospheric before taking the readings.

I t

Data from this test showed that the rate of drift is unaffected by the periodically cycling of the switch.

It 1

also showed that switches with the polished cross-shaft design behave in an identical manner with those (non-polished design) switches in service at LaSalle.

Finally, it i

has shown that Model B212 switches such as are used for the Level 3 scram function exhibit an average of about 1.6" W.C.

l drift when not adjusted for a period of three months.

This i

data has been used in the evaluation which resulted in the j

recommendation to change the reactor level 3 switches'

]

calibration surveillance to monthly.

(See section II.)

I Appendix B provides an evaluation summary of the drift data

]

from the SOR Long-term test program.

The following graphs demonstrate the general trend that the switch drift has exhibited from the program's inception in July, 1986,_through the most recent data set taken on December 8, 1986.

APPENDIX O SOR Differential pressure Switch Diaphragm Failure Investigation D-1 l

~

_]

O APPENDIX D SOR DIFFERENTIAL SWITCH DIAPHRAGM FAILURE INVESTIGATION The failure of 2E31-N013BB on December 10, 1986, initiated the investigation of all previous failures. Due to difficulties at LaSalle in finding the necessary work requests, this raw data was not obtained until December 18, 1986. A rough draft of the above was provided to an NRC resident inspector on December 18, 1986.

Investigation of the information is still in process.

Between December 16 and December 18, six (6) SOR switches were examined at LaSalle and at SOR Inc. for diaphragm damage. The results of the examinations are listed below. The words in quotes are taken directly from the work request. The following information was identified in a search of work request files regarding work done to SOR differential pressure switches.

2B21 - NO37AA WR# L48894. Work completed 5/31/85.

Believed to be microswitch problem. No evidence of diaphragm damage.

Ser# 85-1-2457.

1E12 - N010CA Ser# 85-1-2411.

WR# L52226. Work complete 10/1/85.

" Switch will not trip."

Numerous punctures are in the diaphragm, and a black residue was found in the body cavity.

1E12 - N010CA Ser# 85-6-3587.

WR# L57245. Work complete 4/12/86.

" Pressure across switch would not remain equalized." A puncture tear was found in the diaphragm.

1E12 - N010CB WR# L59561. Work complete 7/18/86.

" switch diaphragm leaks by."

Pinhole punctures similar to those in IE12 - N010CA were found in the diaphragm. Ser# 85-1-2413.

2B21 - NO38A WR# L59802. Work complete 7/17/86.

Believed to be slow leak from hi to low side. Two extremely small pinhole punctures were found in the diaphragm on December 18, but these may have been caused during storage. This switch was disassembled in July 1986 and no damage to diaphragm was observed at that time. Ser# 85-1-2376.

2E31 - N013BB Failed functional test 12/10/86.

Found tear in diaphragm -

may have been due to fatigue. Ser# 85-1-2428.

. Three of these switches were replaced prior to the June 1 incident for various mechanical failures and were not part of the original investigation.

2B21 - NO38A and IE12 - N010CB were disassembled at LaSalle in July and no diaphragm damage was observed. NO38A was not returned to SOR Inc.

because of contamination. N010CB was returned to SOR Inc. where damage to the diaphragm was found. Apparently this damage was missed during the examination at LaSalle. The damage to N010CB was not reported to Commonwealth Edison by SOR Inc. because this failure did not appear to have any bearing on the

" static shift" investigation.

The punctures in the diaphragms of both of the lE12 - N010CAs and 1E12 -

N010CB appear to have been caused by foreign material. All damaged diaphragms are to be tested further in order to determine if the KAPTON material has degraded in any manner.
