===1 Background===
DTE Energy Fermi 2 Power Plant is pursuing a fuel cycle extension from the current 18 months to 24 months, in accordance with the requirements of NRC Generic Letter 91-04 (Ref. 9.1.1). An essential part of this effort is to ensure that the surveillance interval requirements that are tied to the length of the plants nuclear fuel cycle are extended, as necessary, to accommodate the proposed fuel cycle. To verify that the reliability and availability of the components is unchanged by the change in fuel cycle, any failures associated with the performance of these Surveillance Requirements (SR) are evaluated, classified and justified to verify they will not impact plant safety.
The surveillance test history analysis is discussed in Generic Letter 91-04 (Ref. 9.1.1) as required to support the License Amendment Request (LAR) for transition to 24-month fuel cycles. Surveillance test analyses are performed on historical completed Events, as contained within the project scope.
2 Purpose The purpose of this report is to provide a summary of the Technical Specification Surveillance Historical Failure Analysis performed in support of the 24 Month Fuel Cycle Extension Project to ensure that the availability and reliability of systems, components and functions will not be significantly reduced by repetitive or time-based failures.
The project scope includes an analysis for all Technical Specification (TS) related SRs, with 18-month surveillance intervals (or multiples thereof), tied to the length of the plant's nuclear fuel cycle. This includes both outage and non-outage surveillances. All TS SRs in scope were reviewed to determine which Events are used to satisfy the SR.
This resulted in scope as defined by DTE-18005, Rev 2, Attachments 2 and 3.
This Technical Specification Surveillance Historical Failure Analysis documents evaluations performed to identify historical failures, categorize the type of failures, and justify the acceptability of the surveillance interval extension with the existence of these identified failures. Specifically, the analysis, by evaluating each applicable TS SR, supports the conclusion that the impact on system availability and reliability, if any, will be small as a result of the change to a 24-month surveillance interval. This analysis, in combination with applicable Allowable Value and Nominal Trip Setpoint verifications and applicable UFSAR reviews, also verifies that the assumptions in the plant-licensing basis are maintained.
3 Design Inputs 3.1    The 24 Month Project Team performed a review of all TS Surveillance Requirements (SRs) that would require a change in the performance frequency to support the change to a 24-month fuel cycle. The SRs and Events identified as within scope were documented in DTE-18005, Rev 2 Attachments 2 and 3.
All available performances of the applicable Events were collected from the site document control system (i.e., WebARMS). Each collected performance was reviewed to identify any failure of the procedure and then each failure was evaluated to determine if the failure resulted in a potential for the SR to not be met. Attachment 2 identifies the Events associated with the scoped Technical Specification SRs.
3.2    Copies of the completed Events were obtained from WebARMS searches. These completed performances were used to provide the necessary failure information.
Page 4 of 10
 
TRVEND 24MCGNF319001 Rev 1 Page 6 of 395 Engineering Report No. DTE-19001 Revision 1 Where Event performances referred to a CARD (Condition Assessment Resolution Document) and/or Work Orders, these documents were also obtained from WebARMS searches, in order to provide the information necessary to categorize and assess consequences of the failures.
3.3    Event 0350, Perform 24.630.01 Remote Shutdown Panel Control Circuit/Switch Test, Procedure 24.630.01, Rev 35 was revised and issued 11/16/2016. Procedure 24.630.01, Rev 34 included 9 separate sections, 5.1 through 5.9, which for purposes of performance were sectioned off into seven Sub-Events: 0350, 0350A, 0350B, 0350C, 0350D, 0350E and 0350F. Procedure 24.630.01, Rev 35 includes 5 separate sections, 5.1 through 5.5 and is performed by five Events: 0350, 0350A, 0350B, 0350C and 0350F. Event 0350 is at times completed by entire performance of 24.630.01 or a combination of sections (e.g. 5.1, 5.2, 5.3, etc.) of the surveillance to complete the entire surveillance performance.
Events 897, 3300, 3301, 3302, 3304, and 3307 series for Instrument Line Excess Flow Check Valve (EFCV) Functional performances are also, depending on scheduling, completed by a series of Sub-Events (A, B, C, etc.) in order to complete the entire required performance or completed entirely in one performance.
3.4    As related to Event performances which included Acceptable Performance Tolerance (APT) range, position taken with regard to failure analysis is:
3.4.1  If As Found data is NOT within APT range, then performance is considered to have failed and Description of Failure is documented.
3.4.2  If As Found data is within APT range but NOT within the As Left Tolerance (ALT) range, then performance is NOT considered to have failed; no Description of Failure is documented.
3.5    For Events reviewed associated with leakage detection, any leakage indicated during the Event performance is considered a Category A failure unless it exceeded allowances provided within the surveillance Acceptance Criteria. In this case, it is considered to be Category D.
4 Assumptions To complete this analysis, the following assumption was made to clearly define the scope of the analysis and the methodology used to evaluate the surveillance test history. The generic assumption, with a bases statement to justify the assumption, is presented as follows:
4.1    The review of the credited Event performances, within a time frame required for a minimum of five Event performances (18-month frequency), can be used to evaluate the Event test history and support the justification to extend the associated TS SR Frequency to 24 months (maximum of 30 months with the allowance of TS SR 3.0.2). Generally, only a review of the surveillance tests which implement the 18-month TS SRs is required.
Bases:
Five surveillance test performances (approximately seven years of history for 18-month frequency) provide an adequate performance history. As stated in the review methodology, the surveillance test history analysis is a qualitative review of the surveillance test performances to ensure there is no evidence of any repetitive Page 5 of 10
 
TRVEND 24MCGNF319001 Rev 1 Page 7 of 395 Engineering Report No. DTE-19001 Revision 1 failures associated with the surveillance requirement which would invalidate the conclusion that the impact on system availability, if any, will be small as a result of the change to a 24-month surveillance interval. The five performances ensure that approximately three 30-month surveillance periods are reviewed to identify any repetitive problems. It has been concluded, based on engineering judgment, that three 30-month periods provide adequate surveillance test history. The aforementioned amount of historical data has been proven to be acceptable by the United States Nuclear Regulatory Commission (USNRC) in previous nuclear plant (i.e., Perry Nuclear Plant, Hatch Nuclear Plant, DC Cook Nuclear Plant and Oconee Nuclear Station) license submittals for surveillance interval extensions.
5 Methodology 5.1  Background/Overview of Methodology As stated in the Purpose section, this analysis (the scope of which is defined in Attachment 2) is being performed to confirm that the impact on system availability, if any, from the change to a 24-month surveillance interval will be small. To confirm this conclusion, it is necessary to demonstrate that the surveillance test history does not indicate a history of repetitive failures, which would go undetected if the current surveillance interval were extended to the proposed surveillance interval.
The purpose of surveillance testing is to verify that the tested TS function/feature will perform as assumed in the associated safety analysis. By periodically testing the TS function/feature, the availability of the associated function/feature is confirmed. As such, with the extension of TS SR intervals, a longer period of time will exist between performances of the surveillance testing. If a failure, which results in the loss of the associated function, should occur during the operating cycle which could only be detected by the testing associated with the operating cycle-based TS SRs, then the increase in the surveillance testing interval would result in a decrease in the associated Functions availability.
To ensure the acceptability of the change to a 24-month (from 18-month) surveillance interval, a two-step process was employed for TS SRs. The first step was a qualitative review of the associated TS SR. A qualitative evaluation of each TS SR was performed to document the acceptability of going to a TS SR Frequency of 24 months. These evaluations employ arguments similar to those suggested in Generic Letter 91-04 (Ref. 9.1.1), such as redundant channels and more frequent testing performed during the operating cycle. These qualitative evaluations should be applied in the Documentation of Change accompanying the TS change submittal.
The second step is the evaluation of the surveillance test history which is being performed in this analysis. This evaluation is being performed to confirm the general conclusion reached as part of step one. The results of each of the qualitative evaluations may be found in Attachments 3, 4 and 5 of this report and are also summarized in Section 7.
5.2  Surveillance Test History Analysis Methodology As established in Section 5.1, the two-fold purpose of the analysis is: 1) to ensure that there is no evidence of repetitive surveillance test failures which would potentially result in a decrease in the system availability from the change to a 24-month surveillance interval, and; 2) to ensure that there is no evidence of repetitive surveillance test failures which would indicate that the current 18-month surveillance Page 6 of 10
 
TRVEND 24MCGNF319001 Rev 1 Page 8 of 395 Engineering Report No. DTE-19001 Revision 1 interval does not provide adequate system availability and reliability. To demonstrate this, a review of the surveillance test history has been performed. Only a review of the surveillance tests which implement the 18-month TS SRs is required.
Failures detected by more frequent surveillance tests are not being impacted by this change and will continue to detect failures which have been previously detected by these activities. To simplify the evaluations necessary for this analysis, surveillance test failures have been classified into categories which can, in most cases, be generically justified. The classification technique is graphically shown in Attachment 1, and each of the failure categories is described in Section 6.1. As is explained in Section 6.1, the failures in each of these categories can be demonstrated to not change the conclusion that the impact on system availability, if any, will be small as a result of the change to a 24-month surveillance test interval. The one exception to this conclusion is Category D Unique Failures.
To ensure that repetitive failures of similar components tested by different surveillance tests would be identified, a separate evaluation was performed of all the Category D failures. This evaluation, documented in Section 6.2, reviews the Category D failures from this analysis as a group to determine if there is any evidence of repetitive failures among similar plant components.
These two evaluations (failure categorization and review of unique failures) identify any repetitive failures which could potentially invalidate the conclusion that the impact on system availability, if any, will be small from the change to a 24-month surveillance test interval.
5.3    Determination of Scope As stated in Section 2, the purpose of this analysis is to support the conclusion, for all TS SRs (as displayed in Attachment 2 of this analysis) which are being changed to a 24 month surveillance interval, that the impact on system availability and reliability, if any, will be small as a result in a change to the surveillance interval.
The total scope of the TS SRs requiring review, along with the applicable Events which satisfy those requirements, is identified in Attachment 2. Therefore, Attachment 2 provides the total scope of Events requiring review.
6 Detailed Discussion 6.1    Surveillance Test History Categorization and Evaluation As stated in Section 5.3, the Events requiring review are identified in Attachment 2.
For each of the identified Events, all credited Event performances occurring over at least the past seven years which were available for review, have been retrieved and any identified failures have been evaluated and categorized into one of the five categories identified in Attachment 1. As stated in Section 5.2, the categories have been established to simplify the review process. In the following paragraphs, a basis is provided to justify why each of the failure categories does not impact the conclusion that the impact on system availability, if any, from a change to a 24-month surveillance test interval will be small.
CATEGORY A - NO LOSS OF DESIGN/SAFETY FUNCTION Bases:
A Category A failure is one in which there is no impact on the ability of the component and/or system to perform its specific design/safety function. A typical Page 7 of 10
 
TRVEND 24MCGNF319001 Rev 1 Page 9 of 395 Engineering Report No. DTE-19001 Revision 1 and common example of this type of failure is one where the surveillance requirement is to verify that a breaker trips on overcurrent. The test record verifies this action, but observes a failure of an indication of this trip. The indication is not the safety function being tested, but the breaker trip is. The Category A failure does not result in a loss of the design/safety function and therefore, does not affect the operability of the component or the ability of the equipment to perform its intended function. Category A failures are not considered significant failures relative to the other failure categories. If the failure of the surveillance test did not result in the failure of the associated component and/or system to perform its function, and the TS requirements were satisfied, then these failures have no impact on system availability. Therefore, these failures do not impact the conclusion that the impact on system availability, if any, from the change in the surveillance test interval is small.
CATEGORY B - MORE FREQUENT TESTING Bases:
A Category B failure is assigned to surveillance test failures which would be detected by the performance of other required testing or plant monitoring activities that are performed more frequently. An example of a Category B failure would be finding level in a tank below the required value during an 18-month surveillance, when a Channel Check or Operator Log procedure requires this level to be verified above the same or more conservative value on a more frequent basis (such as quarterly or daily). It is anticipated that the inadequate condition would be discovered during the performance of the surveillance performed more frequently than the 18-month surveillance. If the failure can be detected by a more frequently performed test or monitoring activity, the extension of the surveillance test interval will have no impact on system availability because the failure would be detected by the more frequently performed activity and would not go undetected for a longer period of time as a result of extending the current surveillance interval. Therefore, these failures do not impact the conclusion that the impact on system availability, if any, from the change in the surveillance test interval is small.
CATEGORY C - EVENT DRIVEN FAILURES Bases:
A Category C failure is assigned to surveillance test failures where the cause can be directly attributed to an associated event such as a preventative maintenance task or a modification. An example of a Category C failure would be a procedure deficiency in which the surveillance procedure was unable to be completed as written due to the implementation of a modification that may have altered the plant installed equipment but was not reflected in the surveillance procedure. Also, if the failure has been caused by an event such as a modification where the performance of the surveillance test will be required to demonstrate the operability/functionality of the system or component prior to declaring the associated system operable/functional, then this failure has no impact on the system availability.
Therefore, these failures do not impact the conclusion that the impact on system availability, if any, from the change in the surveillance test interval is small.
Page 8 of 10
 
TRVEND 24MCGNF319001 Rev 1 Page 10 of 395 Engineering Report No. DTE-19001 Revision 1 CATEGORY D - UNIQUE FAILURES Bases:
A Category D failure, or a unique failure, is a surveillance test failure that does not occur on a repetitive basis and is not associated with a time-based failure mechanism. If the failure was caused by a unique failure, then any subsequent failure which could occur would not result in a significant impact on system/component availability. That is to say that any subsequent failures would not be of the same type as previously experienced since the original failure, classified as a unique failure, would not occur on a repetitive basis or be associated with any time-based mechanism. This conclusion is based on the fact that generally all impacted systems are designed to be single failure proof and a unique failure of one of the associated systems/components will not prevent performance of the function. Therefore, these failures do not impact the conclusion that the impact on system availability, if any, from the change in the surveillance test interval is small.
CATEGORY E - ADDITIONAL EVALUATIONS Bases:
If the failure cannot be grouped in any of the previous categories, A through D, then it is assigned Category E and requires additional evaluations to determine if the extended surveillance can be justified. If the surveillance cannot be justified, then an evaluation is made to determine if the surveillance test can be performed at power.
All of the Events requiring review have been evaluated and any surveillance test failures were identified and categorized. Once this step was completed, a qualitative review of each surveillance test failure was performed and a determination was made as to whether the surveillance test history supports the change to a 24-month surveillance interval. Once all the associated Events were reviewed for a particular TS SR, if all these supported a change to a 24-month TS SR frequency, the associated TS SR was identified as acceptable for a change to a 24-month surveillance interval. This evaluation is documented in Attachment 3.
6.2    Review of Unique Failures As stated in Section 5.2, a separate review of the Unique Failures from this analysis (documented in Attachment 4) was performed to ensure that no repetitive failures of similar components occurred under different Events. This review was completed by performing a review of all the Category D failures identified in this analysis as a group to determine if there was any indication of a repetitive failure mechanism or a time-based failure mechanism. Attachment 5 contains this evaluation for each Unique Failure with a summary of the conclusion for each failure.
6.3    Additional Evaluations There were no failures identified in the analysis which have been classified as Category E failures.
7 Summary of Results A Surveillance Failure Analysis was performed for the Surveillance Requirements and associated events listed in Attachment 2. The analysis of each event is documented in Attachment 3, and only 4 unique failures were observed over the study period, as Page 9 of 10
 
TRVEND 24MCGNF319001 Rev 1 Page 11 of 395 Engineering Report No. DTE-19001 Revision 1 summarized in Attachment 4. Analysis of these failures as documented in Attachment 5 concludes that none are of a repetitive nature which would preclude extension of the surveillance interval from 18 to 24 months. For each event analyzed in Attachment 3, it is concluded that the surveillance test history supports the conclusion that the impact, if any, on system availability will be small as a result of the change to a 24 month surveillance interval. Therefore, the Surveillance Failure Analysis supports the extension of frequency for each of the Surveillance Requirements listed in Attachment 2 from 18 to 24 months.
8 Conclusion and Recommendations All DTE Energy Fermi 2 Power Plant TS SRs (under the scope of this analysis, as defined in DTE-18005, Rev 2 Attachment 2 and 3), Events and associated failures have been reviewed and found to support the general conclusions required by Generic Letter 91-04 (Ref. 9.1.1). There is no evidence of repetitive failures or failures with a time-based failure mechanism which would invalidate the conclusion that the impact, if any, on system availability will be small as a result of the change to a 24-month surveillance test interval.

During performance of the procedure the breaker was racked from disconnect to test and was cycled closed and then back open. Test leader and work group supervisor were informed. With test leader and work group supervisor concurrence the hardware was removed from the cubicle and the procedure was completed satisfactorily. After the procedure was completed the breaker was removed from the switchgear and left removed for subsequent inspection. The hardware that was removed from the cubicle has been given to the Component Engineer. An inspection should performed of the breaker to determine the cause and replace the hardware. A review of past CARDs documents a potentially similar event on CARD 09-22885 at breaker 64A-A7." As described in investigation: "the 3/8" bolt, nut, and lock washer found were found in the front of the cubicle near the lower left corner of the breaker. This is one of the two bolts that mount the racking mechanism to the breaker. The second bolt, nut and washer are orientated at a right angle to the bolt mentioned above. At all times the racking mechanism was fully attached to the breaker and permitted the breaker to be racked in or out as needed. The loss of this bolt would not have affected the function of this breaker."
Reportability/Operability Review states: "This is the maintenance tie breaker and would only be used to power the bus during outages. To support the bus operability the breaker would have to have the ability to open to load shed the bus in a loss of voltage scenario.
Because the breaker has been removed from the cubicle it is in a condition that would support its accident condition and therefore the switchgear is OPERABLE." Cause states: "The nut was not sufficiently tightened, but the cause cannot clearly be determined. The work was completed four years ago. Some contributory causes at the time may have been time pressure to complete the refurbishment combined with an underlying reduced emphasis on human performance tools. The station's human performance program has been significantly enhanced since 2005. A review of the procedure 35.304.010 was conducted and found to be adequate. However it should be noted that 35.304.010 is currently in revision to include additional points for verification DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                      1-July-2019                                              Page 3 of 270

The load test was suspended and calibration of the battery charger performed with no issue noted. The charger load test was then re-performed satisfactorily. The most probable cause for the low voltage reading on the initial test is a degraded cable connection in the test setup.
Since this was a test equipment issue and the test has been re-performed successfully this condition does not impact the ability of 2A-1 to perform its safety function. The new cables will be installed prior to the next performance of the charger load test.

The following readings were taken while the unit was shutdown with the aux oil pump running per step 5.1.14: 1) Oil supply to trip unit (E41-Ra06)-23.5 psig, allowable 17-21 psig, 2) Thrust bearing pressure (E41-RA11)-11.5 psig, allowable 14-18 psig, 3) Overspeed Trip inlet pressure (E41-RA10)-23 psig, allowable 17-21 psig, and 4) Coupler Bearing Pressure (E41-RA13)-13.5 psig allowable 9-13 psig. All of this data was forwarded to the system engineer and no actions are recommended at this time. None of the readings were acceptance criteria and no unexpected alarms were received during the run. CARD Reportability/Operability Review states: The gage E41RA11 still reads 12# with the oil system shutdown and needs to be replaced. This failed instrumentation does not make the HPCI pump INOPERABLE. This reading is acceptance criteria for 24.202.01 and needs to be available for the next run of the surveillance once the issues with the first performance are resolved involving the affect on RCIC during the HPCI surveillance run. Authorized a scope add to get a package to replace the gage. Each of the noted oil pressures (with one exception) were slightly out of the band high due to cold oil on the initial start of the lube oil pump and HPCI turbine. This has been discussed with the system engineer and is acceptable. During the HPCI run those oil pressures dropped down into the acceptable band as the oil heated up. The one exception was the thrust bearing oil pressure, which was low out of the band at 11.5 psi, with an acceptable band of 14 - 18 psi. This was the result of a failed pressure gauge (as discovered by the fact that it continued to read approximately 12 psi after the oil pump was shutdown), which was replaced under a work order 29766192 the following day.

closed direction. According to Drawing 1-2221-08, it appears there is a problem in the opening circuit seal-in through the closed pushbutton. Based on the fact that the valve properly strokes closed and it opens when the pushbutton is held, there is no concerns with the auto positioning circuitry." CARD 12-24169 Reportability/Operability review states: "The suction for HPCI comes from either the CST or the Torus. The E4150F042 is the suction from the Torus. The valve still functions strokes closed as required which supports the Primary Containment isolation function. The valve open contactor functioned and the auto open signal does not rely upon the seal-in from the closed push button as the auto signal is a contact from a relay that goes directly to the contactor so the function to support HPCI operability is maintained. The HPCI system and primary containment isolation valve are OPERABLE because the valve is still capable of auto opening and closing to support the design functions." Work Order 34450676 was previously written on 5/8/12 to correct valve issue. On 5/27/14, WO found broken Aux contact O/A, removed contact and replaced with new one from stock.

The review of WO 36700624 in CARD 14-22730 indicates that per the valve diagnostics, 32.0 psig is approximately half stroke. Full stroke appeared to be at 35.0 psi during the valve diagnostic. This is an approximation based on looking at graphs. Conferred with the AOV engineer, and the calculated full stroke psi from the diagnostic data is 34.7 psi.
This supports that the lack of full stroke length is due to low air pressure and not from valve friction.

Reportability/Operability Review states: Declared LPCI Swing bus inoperable and added condition to LCO 2016-0381. Applied mode 1, 2 and 3 restraints." CARD Cause: "The Direct Cause was: Degraded CT. This was the only change to the circuit since successful completion of the circuit. The Apparent Cause is Abnormal Electrical Stress from a loose connection/open circuit in RF17 (CARD 15-28495). The open circuit of the CT in RF17 could have developed high voltages and degraded the CT. This degradation cannot be detected at low current test conditions. Due to the fast acting relaying the high voltages may not have been long enough in duration to cause a complete failure of the CT. A Contributing Cause is Degradation of the 87 relay time delay. Original manufacture time delay curve states the relay should actuate between 14 and 38 milliseconds and should be around 30 at the test values utilized by Fermi. The 87 relay is actuating at 8 milliseconds. Cause Code E01-Setpoint Drift. Corrective Actions:
DC/AC-Replace the affected CT's at 72C-F MCC completed. CC-Replace the 87 relay with a relay including a time delay per ERE-44596 - completed. The extent of the apparent cause is limited to CT's that have been open circuited. There is one other known occurrence in which a CT was open circuited. This was the failed knife switch in the 345KV relay house coming out of RF17. This CT has been operated throughout the last cycle in the range it is expected to operate at and has not shown any degradation.
The extent of the contributing cause is limited to the 50 and 87 relays in the 72C-3C circuit. The model relay was not found used in any other locations. The 50 and 87 relays were replaced under ERE-44596. This failure was determined to be a Functional Failure as when breaker 72C, position 3C tripped unexpectedly this resulted in inability of the DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                      1-July-2019                                            Page 22 of 270
 
breaker to supply power to MCC 72-CF which is a risk significant load. Failure of          TRVEND 24MCGNF319001 Rev 1 Function R1400-01 resulted. MRFF Evaluation Justification states: The causal analysis                Page 136 of 395 determined that the cause was most likely that the CT was degraded during the RF17 event in which the CT was open-circuited. Fermi performed testing on the CT which did not reveal the degradation due to the differences in testing capabilities and in-field currents. There was also no OE or industry recommendations to suggest that the CT should be replaced just because it was open-circuited since it passed testing. The closest cause code is M3 as the CT tested SAT and there was no industry recommendation or OE available to suggest that any other actions should have been taken in RF17 to prevent this failure. Therefore this is not a Maintenance Preventable Functional Failure.
The performance criteria of 0 bus failures has been exceeded. CARD 17-23803 has been submitted to evaluate the system for classification of (a)(1) status. CARD 17-23803 states: The system has been evaluated for (a)(1) status and the 8/7/17 MR Expert panel approved the system to remain (a)(2). This recommendation is because the only maintenance preventable failure was an HU issue not an equipment issue. There are also no actions to be driven by a Get-Well-Plan to improve the reliability of the equipment.
WO 47455670 replaced CT-1 Current Transformers with new CTs in MCC 72C-F, position 1C and also replaced both 50 & 87 relays at Bus 72C-3C. Partial performance of 24.204.03, Section 5.2 was performed as PMT for this Work Order.

Reportability/Operability Review states: "E1100F050A did not indicate full open during surveillance testing. The local position of the valve was verified to be full open. A limit switch adjustment is required. The limit switch for the E1100-F050A was adjusted by I&C and the test reperformed Sat." Maintenance Rule Functional Failure evaluation completed, it explains: "the safety related functions of the E1100F050A are to open to permit LPCI flow to the reactor vessel during a postulated LOCA and to automatically close upon cessation of flow to maintain reactor coolant pressure boundary. The non-safety related function is to open to permit flow for the Shutdown Cooling mode of operation. The condition described in the CARD is concerned with the ability of the valve to stroke with the actuator - i.e. the limit switch was required to be adjusted to resolve the indication issue. This condition had no effect on the ability of the check valve to physically open or close. Each of the potentially-affected functions were retained, and no MRFF occurred."

Reportability/Operability Review states: "The condition of the RCIC turbine oil filter inlet pressure indication on E51-RA01 being less than allowable band is 13-20 psig, recorded pressure 12.5psig, has been attributed to instrument error by the System Engineer based upon past performances RCIC surveillance run. System Engineer comments: "The last time this low press surveillance was performed (4/09) the oil dp was 1.5. The last two high press surveillances (5/10 and 8/10) the oil filter dp was 2.0.
Since the oil outlet pressure was 12.0 psig, using the same 1.5 psid (since no work was performed on the oil system) the inlet oil pressure was about 13.5 psig. This would indicate that the gauge is not reading correctly, and may need calibration." Additional comments provided indicate oil filter outlet pressure was in band at 12 psig, therefore adequate oil pressure to the machine exists. System Engineer calculated inlet oil pressure was about 13.5 psig, which is an acceptable oil pressure. RCIC lube oil system is capable of adequately supplying the required lubrication for RICIC operation. RCIC is capable of meeting the safety related functions and is OPERABLE."

Two different procedure changes were requested by CARDs 09-23429 and 09-23471. The 09-23429 CARD was closed to the 09-23471 CARD. The closed CARD (09-23429) information was included in the immediate actions of the open CARD but was missed by the CARD owner and the technical reviewer during the procedure revision 49 process. A review of the procedure revisions found that rev 44 had the correct information for step 5.2.40 to verify the alarm clear. However revision 45 (2008) changed step 5.2.40 from clear to alarm. There is no change summary or revision bar for this step to be changed. Therefore this step was inadvertently changed and was not caught during the revision 45 change, done after RF12." This discrepancy was found during the cyclic performance of the procedure during RF13 and was not corrected for the RF14 performance. This event was determined to be an Engineering Human Performance (HU) Event. Procedure revised by DCR 10-1600 to change the alarm status verification from alarm to clear.

Under troubleshooting WO 38172364, the 12EB-EB3 breaker was functionally tested and the following relays were tested: T3A1, 59SX, 59S, 1MV62 and 27X-12EB. All testing was performed satisfactorily, except for time delay testing of relay 1MV62. The initial as found time delay was 16.56 seconds. The time delay testing was repeated numerous times, however the relay was never able to meet the ALT of 4.5825 - 4.8175 seconds and there was no repeatability in the values; repeat attempts were 6.38, 7.00 and 6.51 sec's, the setpoint is 4.7 sec. The relay contacts were verified to be changing state and working properly.
CARD 14-22732 was written to document failed relay. CARD 14-22732 states:
Performing WO 38172364, testing relays due to EDG12 not meeting LOP/LOCA criteria, found time delay relay 1MV62 (print I-N-2572-18) high out of spec and could not adjust the relay to meet acceptance criteria. WO 38172364 allows replacement of the relay if found out of spec. 1MV62 relay was replaced with a bench tested relay from stock and the PMT (24.307.02, Section 5.2) was completed satisfactorily. CARD 14-22590 Description/Investigation notes state: The 1MV62 time delay relay is a 125 VDC Agastat 7012PB (delay on pick-up) model with a range of 0.5 to 5 seconds. Per CECO, it is QA1, Seismic I and Tech Spec related. A review of the work history revealed that the relay set point had been 1 second until RF14. EDP 35621 Rev A (Degraded Voltage Improvements) revised the time delay setting to 4.7 seconds for all the load shed time delay relays (4) for the EDG output breakers. This change was to ensure that during a degraded voltage event coincident with a LOCA, there is adequate time from the initiation of load shedding for voltage to decay at large motors prior to the EDG output breaker reclosing. The 1MV62 relay was as found within the 1 second APT (0.9 to 1.1 sec) and then adjusted to within the new ALT (4.5825 to 4.8175 sec) and tested twice DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                      1-July-2019                                              Page 33 of 270

An evaluation of the current Agastat 7012PB                          Page 147 of 395 model relay for the load shed time delay application was completed and it was determined, with EFT support, that the 7012PC model is more appropriate for the application. The current 4.7 second time delay setpoint for the relays (7012PB) is near the end of the 0.5 to 5 second timing range. The setpoint of 4.7 seconds is within the timing range; however, VMR4-9, for Agastat Timing Relays, states that for easiest adjustment and lowest cost, the shortest time range suitable for the application should be selected. The next highest range is the 7012PC with a range of 1.5 to 15 seconds. Four WOs were created to replace the existing relays with the 7012PC model, or equivalent.
To date (July 2018), per Maximo, two WOs, 38563406 (11EA) and 38182257 (13EC) have been completed. CARD 14-22590 Failure Information details: The slow time occurred while performing 24.307.02 (ECCS Start w/ LOP) Section 5.2 of, however Section 5.1 (LOP) had been performed successfully and the output breaker closed in under 10 seconds. Since the output breaker had closed in under 10 seconds for Section 5.1, there is reasonable assurance that the failure had occurred when Section 5.2 was performed. A review of all the EDG 12 supported loads was performed by PSE to determine the impact of the 2.2 second delay in 12EB-EB3 closure time. Based on review, the delay would not have affected the availability of the EDG 12 support and auxiliary equipment (MCC 72EB-2D), as this equipment, is not sequenced on for at least 45 seconds. Per DC-6034, Vol I/II and TRVEND GE14 LOCA Report Rev 1, the LOP/LOCA response assumes a 20-25 second EDG starting delay. Additionally, low pressure injection is delayed approximately 10-13 minutes for the limiting small break LOCA. There would be no impact to the essential room coolers supported by EDG 12 (Div 1 Battery Charger/MCC area, Div 1 SGTS Fan, Div 1 RHR, Div 1 Thermal Recombiner area and Div 1 EECW area) as the delay is judged to be well within the thermal inertia of the room heat sources and sinks such that its effect on area environmental responses would be expected to be negligible. The review also determined that all the Div 1 EDG 12 supported valves would not be affected by the delay. EDG 12 remained capable of performing its required MR functions under design conditions with the output breaker closure time of 12.22 seconds. Therefore, there was no loss of functions R1400-01, R1400-02, R3000-01, R3000-02 and R3000-07. There was not a MRFF for R1400 or R3000, or an R1400 bus failure. This failure would not have resulted in the inability to control a critical safety function (e.g. Reactor water level and pressure, Primary and Secondary Containment, Drywell temperature and pressure, Spent Fuel Pool temperature and level, etc.), or capability to shutdown the Reactor and maintain it in a shutdown condition. The EDG did start and load. The EDG's are considered a "CC2", which is a Low Critical Component defined in AP-913. By definition, a CC2 component cannot cause a loss of a critical safety function. The 10 second start criteria is a design requirement listed in the UFSAR. Although the EDG did start and load, it did not meet the Technical Specifications and UFSAR design criteria description. Additionally, an evaluation of the current PM strategy for the EDG output breaker load shed time delay relays was performed and the frequencies of PMs R931 and R932 were revised from 3300 days to 2200 days (4R).

Closure Summary states: THE DIRECT CAUSE IS: E01 Setpoint Drift, because the as                            TRVEND 24MCGNF319001 Rev 1 found time delay of 1MV62 was 16.56 seconds, as opposed to the setpoint of 4.7 seconds                                      Page 148 of 395 with an APT of 4.5546 - 4.8454 seconds. The setpoint drift of the relay caused the EDG 12 output breaker 12EB-EB3 to close in 12.22 seconds after the EDG 12 emergency start signal.

Wiring inspections were SAT, if mechanically bound, the breaker would prematurely trip free when racked out and it did not (eliminating binding). With the breaker removed from the cubicle, approximately 10 ohms resistance was identified from 52XX contact 2-8 to the secondary disconnect 3 with the 52XX contact closed. The resistance was likely much higher at the position the breaker was sitting on the secondary disconnect, however to perform this measurement the breaker has to be racked out (thus wiping the contact). It is concluded that the cause of this failure was a high resistance secondary disconnect due to poor condition which could have been prevented through proper maintenance practices. Therefore, this was MPFF cause code (E10) Personnel Error."
WO 34392170 performed; secondary disconnects were cleaned and breaker was functionally tested SAT.

== Conclusion:==
This is partly attributed to not being allowed to use wire brushes in switchgear anymore due to FME along with not spending the time need to get the contacts properly cleaned. An alternate method needs to be identified to allow a more positive cleaning of the contacts. From CARD Action Item Completion Comments: 07/20/2012 11:39:28 AM Communicated this event to the Electrical Department at the refocus meeting on 7/19/12. The group brought up the issue of not being able to use wire brushes when needed in the RRA for appropriate work activities mainly cleaning the secondary contact. Comments relayed were that we can still use them we just have to spend the time to get the proper paperwork filled out to get the brush approved for the job. Discussion included the need to take the time required to perform the work correctly the first time. Maintenance Rule Functional Failure form completed, Justification states: "The Maintenance Rule Specific Guidelines for R1400 is "A loss of Switchgear (electrical bus) or switchgear position resulting in the loss of another SSC's Maintenance Rule function is a Switchgear FF". The load shed portion of maintenance rule function R3000-01 was maintained when the breaker tripped as required. The breaker failed to close, however the load sequencer close signal was received as verified by the 52XX relay energized and close signal validated at 52XX contact 2-8 lower terminal during MMA26 troubleshooting, thus the load sequence portion was met as well. When the breaker failed to close, MR functions T4600-01 and R1400-02 were not maintained, therefore this was a MRFF.

ACE investigation for CARD 13-25574 had determined the EDG 14 pipe nipple was found broken during implementation of WO# 013B881201 (Repair/Replace Damaged Air Pressure Regulator R30F047D to R30-PI-RA07D) in the year 1988. A review of this WO had determined that it is probable the pipe nipple was incorrectly replaced with Schedule 40 pipe, rather than Schedule 80 pipe, during implementation of WO#
013B881201 in the year 1988 even though the WO did not specifically state the nipple was replaced. The as-found installation of Schedule 40 pipe nipple contributed to the unplanned shutdown of EDG 14 during a 24 hour run on 8/9/13 (CARD 13-25574). As noted in ACE for CARD 13-25574 timeline of some key events are: 1) "EDG 14 air cooler temperature transmitter pneumatic R30NA18D was found failed during EDG 14 air cooler temperature control loop calibration check per WO 30897690.

APPARENT CAUSE ONE IS - Incorrect Material Identified - The pipe nipple air line fitting between relief valve R3000F048D and pressure regulator valve R30FA01D on EDG 14 had completely sheared due to the use of schedule 40 pipe as opposed to schedule 80. APPARENT CAUSE TWO IS - Abnormal Stress - The use of U-bolts to support the connecting valves R3000F048D and R30FA01D caused bending fatigue on the pipe nipple fitting MRFF = Maintenance Rule Functional Failure Yes MSPI =
Mitigating System Performance IndicatoNo MPFF = Maintenance Performance Functional Failure = No Revised MSPI basis failure criteria for this MRFF as the previous basis wasincorrect. MSPI basis documentation (WebARMS DSN: MSPI) states in Table 1-SC that one of four EDGs are required for the EDG system to provide its MSPI function. Further, credit can be taken to crosstie an EDG to other ESF busses within the same division. This is accomplished via procedure 23.321. Based on this reason, the existing MRFF was revised to remove the MSPI failure.

however, the PCIV function of valve T50-F450 is not impacted due to the fact that the valve remains closed. CARD 15-20450 lists the direct cause of the failure to be an out of calibration OPEN reed switch. CARD 15-20450 also indicates that the valve is tested every 91 days for Operability, Calibration, and Stroke Position per Section 5.1 of this same surveillance procedure, 24.408.03. WO 42407068 was initiated on 01/20/2015 to test, adjust position switches for T50-F450. WO troubleshooting found that loosening the open switch clamp screw caused the valve to stroke open and closed as designed.
There is no specified vendor torque for the screw and it is to be adjusted by skill of the craft so the switch functions properly. The valve indication also started working again.
The valve was then stroked multiple times without any failures. The cover for the electric assembly was reinstalled loosely with a new gasket and the valve was then stroked several more times and functioned properly. The valve was returned to service and LCO 15-0041 was cleared.

Reportability/Operability Review states: "SGTS is not required to be Operable in the current mode. Retesting of both divisions of SGTS need to be completed prior to plant startup from RF13." Work Orders 29710795 and 29710836 are referenced, however, per Maximo, both were cancelled. Determined to be M&TE failure, reperform partial surveillance is indicated.

HEPA filter within the compartment directly below testport #11. Request WO to retrieve zip-lock bag during RF17." It was removed on 11/04/15 with work order 44238494.
During performance of this work order the System Engineer removed the bag and inspected the HEPA filters, which are in this compartment, to ensure there was no damage. No damage to the filters was expected and none was noted during the inspection. Primary causes were attributed to Work Quality (Workmanship) to maintain situational awareness and procedure use and adherence. A Crew Learning Opportunity (CLO) was written to share lessons learned. Action Item Completion Comments state:
                        "The functions evaluated for this issue are: Function T4102-03, Maintain Control Center Envelope at a positive pressure with respect to outside ambient pressure in Emergency Recirculation Mode. Function T4102-04, Filtration system ensures that resultant operator doses are within regulatory limits following a DBA. The CCHVAC system was declared inoperable to perform this PST event and was not declared operable again until after the bag was removed and the system returned to normal configuration. The Control Center Envelope was maintained at a positive pressure with respect to the outside ambient pressure prior to and after the bag entered the filter compartment. During this event, the CCHVAC system maintained its T4102-03 function. A small area of a HEPA filter was covered. There was adequate flow through the filtration unit because the Control Center Envelop pressure was maintained. No flow was impeded in the area of the charcoal filter so Operator doses would have been maintained within regulatory limits following a DBA. The unit maintained its T4102-04 function. This event is not a functional failure."

CARD 10-31266 Description/Investigation states: "Step 6.1.13 response time was found to be 54 msec, which did not meet the ACCEPTANCE CRITERIA of < 50 msec, and the Step 6.1.20 response time was found to be 52 msec, which did not meet the ACCEPTANCE CRITERIA of < 50 msec. After Step 6.1.13, the Control Room Supervisor (CRS) was notified, and the situation was discussed with an I&C Supervisor. The Vision XP (RC-058-M , 5/20/2011) data for the Step 6.1.13 response time recorded was downloaded to a memory stick, as well as the previously run 44.010.059 data. The surveillance was continued. When Step 6.1.20 failed to meet the A.C., the CRS was notified, the data was saved as RECORD 12 in BT folder on the hard (C) drive of the recorder, and the surveillance continued. The CRS was notified that Step 8.1 ACCEPTANCE CRITERIA had failed. The recorder was brought back to the I&C shop to download and print out the re-performed Step 6.1.20 results." Investigation determined that the Surveillance was performed on Day shift with SAT results, then re-performed on Nights with UNSAT results. The difference was in the testing method. The SAT performance had the recorder hooked up to the back of the scram light holder. The UNSAT performance had the scram light bulbs removed and a test adapter installed in the bulb socket. The Surveillance performance over the years has been close to the 50ms acceptance criteria.
The slight difference in the times was with the different testing method. Maintenance Rule Functional Failure form documents: "The description of this event indicates that the RPS system met the Maintenance Rule function C7100-02 in that a scram signal was present. The issue is that the signal did not meet the acceptance criteria for response time. The event documents the second time that the procedure was performed. During the first performance (which passed the acceptance criteria) I&C noted that no qualified individual performed the test. The first performance occurred measuring the response across a relay room scram light. The second performance, which initiated CARD 10-DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                    1-July-2019                                            Page 75 of 270

However, the test                                                Page 189 of 395 was repeated later with the scram light installed and measuring the response time across the light (additional path to discharge the energy stored in the scram solenoids) and the acceptance criteria was met. Work Order 32084102, assigned to CARD 10-31266, was cancelled as no corrective actions are necessary. The RPS met the criteria for response time and performed the scram function as expected thus no Maintenance Rule Functional Failure occurred." CARD 10-31266-02 Action Item Completion Comments state: "CARD 10-31320 was also written to address a similar issue. The difference between the two equipment hook-ups is minimal; a couple of milliseconds(ms). The corrective action from CARD 10-31320 was to change the Acceptance Criteria from 50 to 65 ms. Therefore we will not be close to the time and either testing method is acceptable." CARD 10-31320 investigation determined, from the revision history, that up until 44.010.059, Rev 21, the acceptance criteria for the TCV fast closure response time was < 80ms. During revision 22 of procedure 44.010.059, the response time was changed from < 80 ms to < 50 ms using NE-PJ-90-0271 dated May 30, 1990, a letter from PSE to I&C Maintenance. A review of NE-PJ-90-0271 concluded that the change of response time from < 80 ms to < 50 ms during revision 22 of procedure 44.010.059 was an error. As a CAAAC, a cross-discipline group meeting was conducted and determined, the 44.010.057 through 44.010.060 procedures needed to have acceptance criteria changed from <50 milliseconds (msec) to <65 msec." Procedures 44.010.057 through 44.010.060 were revised to change the acceptance criteria Response Time from

This relay controls the minimum amount of time required to allow operators to reset a reactor scram following a reactor scram. There are no Tech Spec or Operability requirements associated with this function." OPERABILITY IMPACT: RPS Trip System B remains Operable. MRFF Justification states: "The sufficient minimum time for rods to fully insert is 8 seconds. The setpoint for the timing relay is 10/ -1, +2 seconds. The setpoint and tolerance allows sufficient time plus margin for the rods to fully insert before a scram can be reset. Once the timing relay has exceeded 8 seconds, the support function of the relay has been met. Since the as found time of the relay was 17.5 seconds, the relay provided the required support function and thus no Maintenance Rule Function was lost. The timing relay does not provide interface to other Maintenance Rule systems that would be impacted by this event. C7100 Maintenance Rule Functional Failure, Maintenance Preventable Functional Failure, or Repetitive Maintenance Preventable Functional Failure did not occur during this event."

Building Area Temp Cal/Func), Instrument & Control Technicians lifted two leads from the same terminal. Both leads were labeled "19". The tech's performed a resistance reading and found it out of spec low. The surveillance was stopped after concurrence with the Shift Manager and the I&C Supervisor. During the performance review it was found that though the tech's lifted the leads from the correct terminal they assumed which lead was the one that needed the resistance reading. They reasoned that this surveillance had been performed successfully in the past and took the reading on the incorrect wire." Resistance values obtained at Step 6.1.20 exceeded tolerance. CARD Description/Investigation states: "Interview with the crew identified that the wires were not marked (e.g. which was the shield and which was the RTD ground). They both were labeled with a "19" wire marker. As it turned out, the last time the surveillance was performed the technicians landed the negative lead and then the shield. When my crew performed it and when presented with two wires on the same term identified as the same wire, they may have assumed the outer most wire was the negative lead as that should be where the technicians who last performed it should have re-terminated it. The technicians sorted out the error and when they went to re-perform the surveillance they added wire markers to better identity the wires so this error would not happen again.
The surveillance was completed and the system restored to normal. This event was shared with the I&C shop, Electrical shop, and the Projects group. The surveillance was successfully reperformed and during this performance a wire marker was put on the correct wire. A review of the panels that contain the terminals of the sister surveillance's revealed no like issues."

I&C Superintendent (Nights) and another Supervisor confirmed that fuses pulled and wire lifted for initial conditions were indeed the correct components called out in surveillance 44.040.009. The OCC initiated an EIT to determine the abnormal response issue." Reportability/Operability Review states: "Impact on LPCI function: The LPCI function was not impacted by this condition and remains OPERABLE. Impact on SDC function: Based on the low decay heat value and the significant cooling capacity available the Decay Heat Removal function was maintained. Div 1 RHR SDC and LPCI are Operable." Licensing Review completed" "Licensing has reviewed the condition and information provided in this CARD and CARD 15-29093; initiated to document and evaluate plant impact. Operations conservatively entered TS 3.4.9; however, there was no loss of SDC. Per the System Engineer, SDC was continually provided to the vessel at all times during this event even while the flow path was not in the normal configuration. SDC flow was taken from the vessel from the B RRS loop and returned to the vessel through the A RRS loop. There was no bypass flow. A review of IPCS data identified that both Div 1 RHR SDC Flow and Div 1 RHR HX Inlet Temperatures remained within the normal variances that were present before and after the event, with no noted changes. Based on all of the above, there was no loss of SDC." Investigation states: "Troubleshooting by the EIT team determined that the cause of the failure was due to the 52H switch in the 65G position G3 breaker failed to changed state when the breaker was racked out. The G3 breaker being racked in is a permissive in the auto-open circuit for the F031A valve and is the only break in the circuit that prevents the valve from opening during the surveillance.
With the 52H switch stuck in the racked in state the circuit remained intact and allowed the valve to open. Maintenance was able to fix the alignment issue with the 52H switch linkages. These linkages and switch operation are checked as part of the 6 year breaker PM. This PM has proven adequate at preventing failures of the 52H switch as this is the first time Fermi has experienced this issue." "THE DIRECT CAUSE IS M11 - Out of Mechanical Adjustment.

                        "CARD documents that the as found readings for D11K816A meter does not meet acceptance criteria for 64.120.040. The D11K816A, Div 1 Containment Area Hi Range Rad Monitor has been declared inoperable and LCO 15-0092 entered. Division 2 CHRRMS is inoperable and LCO 15-0092 entered." Investigation states: "This event is not a failure. The radiation monitor was still able to provide its function throughout the usable range of the instrument despite the 100% scale range being low by 0.03 VDC.
During the performance of 64.120.041, the 100% scale voltage of D11K816A was found to be 9.87VDC when it should have been between 9.90VDC and 10.10VDC. This does not impact the usable range of the indicator during an actual event. As found data was within specification for every test input except for the 100% scale reading which was low by 0.03 VDC. In the Containment High Range Radiation Monitor scale, every reading from 5.8x10^0 through 1.7x10^7 would still give accurate indication to operators during an actual event requiring this radiation monitor. Emergency procedures to determine core damage would still be able to use this radiation monitor to reliably determine cladding loss since a reading of 50,000 R/hr (5x10^4) corresponds to 100%

Troubleshooting under WO 38029454 found a poor connection at jumper bar for a terminal between resistors. This caused the solenoid valve to de-energize, resulting in the UA closing the valve/keeping it closed. WO documents that a high resistance connection was measured across the resistor network (made up of 2 resistors), but resistance measurements across each resistor individually was acceptable. A jumper link (bar) terminal, which connects the two resistors together was tightened, which corrected the high resistance condition. WO 38029454 completed follow-up performance (PMT) on 03/24/2014 satisfactorily. This failure is a Maintenance Rule Functional Failure (MRFF), counted against N3012 (Main Turbine Control System), for MR functions N3012-01and N3012-05. Based on the maintenance performed each outage, maintenance is conducted in accordance with all known industry/vendor recommendations. Failure is not considered Maintenance Preventable.

There is no component failure or degradation that could prevent the equipment from performing its function. The tail pipe pressure switch energizes when there is >30psig in the tail pipe. Since the pressure switch was found BELOW the Leave Alone tolerance the switch would have energized as a slightly lower pressure in the tail pipe. This is more conservative and the pressure switch would have continued to provide the necessary signals into the LLS logic as required.

Investigation states: " The valve was to be replaced during the outage however upon investigation of the disassembled valve it was determined that the bonnet was steam cut and could be repaired. The bonnet was removed from the system and taken to the machine shop for repair. The duration of the required repair conflicted with other outage priorities and the decision was made to repair the vice replace the bonnet. Repairs were performed and the valve was placed back in service. It is unclear at this time why this valve is leaking after just four months.
Until the valve is disassembled we will be unable to determine if the bonnet or other components are the cause for the leakage. The valve has had a history on continued leakage and when the bonnet was found to be steam cut we thought we had discovered the cause." Conclusion states: "The valve needs to be replaced because it is installed for use in the wrong application." The issue is considered rework due to fact the valve failed within 12 months of being repaired. This valve can only be worked during outages and should have been repaired to minimize risk to the safe operation of the DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                      1-July-2019                                        Page 157 of 270

Therefore, 1.64 scfh leakage is attributed to internal leakage, past test boundary valve seats. Test boundary valves with suspected leakage are P3400F015 and P3400F018. Both valves are normally seal locked open. Since 43.714.001 is a Leakage Reduction procedure for identifying external leakage, and identified leakage is internal (past valve seats) troubleshooting of suspect test boundary valves to identify cause of seat leakage, will be performed during next LLRT of P3400F405A/P3400F406A (43.401.387), and P3400F405B/P3400F406B (43.401.386). P3400F015 and P3400F018 act as test boundary valves in these LLRT procedures, which contain troubleshooting steps to identify the source of internal leakage. Next scheduled LLRT on these valves is RF19. No further action is required. CARD is trend only." Reportability/Operability Review states: "P3400F015 and P3400F018 are test boundary valves only, and are not containment isolation valves. No operability requirements are applicable."

Reportability/Operability Review states: "E4100F028 "HPCI steam header drain to main condenser isolation valve" shuts to prevent direct flow of steam from steam piping into main condenser. No impact on system operability should valves fail to close. HPCI remains OPERABLE." No MRFF evaluation required. Investigation determined Procedure 24.202.08 was revised (Rev. 6) to perform closed stroke time for valves E4100F028 and E4100F029 prior to pump test per an NRC concern about preconditioning. At that time, focus was on obtaining baseline data for E4100F029 and two similar RCIC valves because valves did not have any stroke time data. Noted: work to obtain stroke times was on a challenging schedule to be done week prior to RF16.
When WO 37990793 was requested to obtain baseline measurements on E4100F029; E4100F028 was not included. E4100F028 should have been included in baseline testing WO mentioned above because reference stroke was affected. In other words, the former reference stroke time for E4100F028 was performed when all steam was isolated. New sequence placed E4100F028 ahead of pump test where steam was not isolated which had a slight impact on closed stroke time. As a result, when surveillance was performed in August 2014, stroke time of 6 seconds was found to be 0.1 seconds higher than IST upper limit. This is not related to degradation; only a change in test conditions.
Recommended new reference stroke time be created using an IST evaluation and data listed above. Also, procedures 24.202.01 (Event 0249) and 24.202.08 (Event 1100) will be revised to incorporate new stroke time acceptance criteria for E4100F028."

In Step 6.16.1 of SOE 08-05, found an anomaly on top of the black (+)            safety function of the equipment. Therefore, plates of Battery 2B-1. CARD 09-22790 initiated.

A grey material was noted on top of the positive and negative plates during the inspection. This was unexpected. Both the Div 1 and new BOP batteries were inspected and do not exhibit this same anomaly." The CARD goes on to state that a battery representative was dispatched to inspect the condition and determined that the grey material on top of the plates internal to the battery is lead sulfate. The lead sulfate on top of the battery plates will not have an adverse impact on the performance of the battery. In addition to the grey material on top of the plates, some of the cell separators are warped or frayed. Two of the cells (9 and 109) have a white appearance on the side edge of one of the positive (black) plates. Separator material is non-conductive and is used to separate the positive and negative plates from each other to keep them from shorting together. Therefore, any warping or fraying will not prevent the separator from performing its function since this is only seen on the edges of the separator. The last item of interest is the plate straps on a few of the cells do not have a smooth appearance.
This is at the top of the cell where the plates transition to the positive or negative posts that extend to the exterior of the battery. The uneven look of the plate straps is caused by the manufacturing process. If this process was not properly performed, a high resistance connection would cause the battery to fail its load test performed at the factory.

for F006B valve was held, the solenoid picked up, realigned but nitrogen was venting the entire time the pushbutton was held. When the Operator in the field used the breakaway tool the valve did open and proper indication for the disc and actuator was obtained. CARD 12-23741 Reportability/Operability Review states: "The E2100-F006B valve is able to be stroked by the local manual method with proper position indication and flow to the RPV. A separate CARD is being written to change the procedure to include the guidance that was in the previous revision, which allowed local manual operation of the E2100-F006B valve. The valve is currently capable of meeting the Acceptance Criteria in the back of the surveillance procedure; however, the procedure cannot be performed as written. Once the procedure is revised, this issue will not prevent restoration of Div 2 Core Spray system to Operable status. The applicable Maintenance Rule Functional Failure evaluation attached to the CARD states: "The failure of the actuator to open the check valve resulted in the need for manual operation to open E2100-F006B for testing. However, this actuator is used only for testing purposes, and its failure would not have prevented the check valve from opening when required - that is, in an accident scenario with the Div 2 CS pumps running and CS pressure greater than reactor pressure." WO 34381192 was generated to repair the valve. WO removed actuator from valve and rebuilt actuator. Replaced all elastomers, most of which were elastic but flat. Cylinder was SAT. Reinstalled rebuilt actuator and tested valve with satisfactory results.

Supervisor went to field with craft and verified all work performed in step 6.5.4, all Sub Steps and performed; Peer Check and Verification completed. All work performed correctly. Troubleshooting plan presented to Operations and OCC." CARD Reportability/Operability Review states: "EDG 11 is currently inoperable for surveillance testing; condition does not impact operability of EDG 11. EDG 11 will be returned to operable status following surveillance testing." During surveillance testing an unsatisfactory reading was obtained when checking closed contact 5-6 of relay 4A for EDG 11. DMM (Agilent U1253B multimeter) in question uses a very low voltage when measuring low resistance readings. Fluke Model 8060A (M&TE) uses a higher voltage (2.5V) for determining resistances. When the Fluke 8060A was used an acceptable resistance reading was obtained (110 ohms). The higher voltage, used by Fluke 8060A, allowed resistance reading to be measured. Therefore, issue of high resistance measurement is the result of test equipment used and NOT of the contact itself. Test equipment had insufficient voltage to break through the oxide layer present on contacts.
This is not a problem for circuit because normal operating voltage is 130VDC. No maintenance rule or safety related functions were affected. Justification of closed contact using digital multimeters provided in CARD: "System Engineering has determined criteria in section 3.9 of 42.307.01, Rev 35 has been met; therefore, circuit will perform its function as designed."

states: "Due to failure identified in CARD, ACCEPTANCE CRITEREA steps of 42.307.02 are not met. This renders EDG-14 INOPERABLE." Tracked on LCO 17-0027. Completion of the fault tree identified R3001S004-022 Emergency Overspeed Switch (EOS) electronic limit switch had failed. WO 46819697 was created and replaced EOS. EOS was quarantined for further investigation of failure. As documented in EACE: "Infield disassembly confirmed oil present within the EOS, and a degraded oil seal on the EOS housing. EOS housing has an oil seal on the cover that helps to prevent oil intrusion. It should be noted that this switch is not designed to be installed in an oil rich environment. However, the degraded oil seal allowed for the minimal amount of oil intrusion at this location. As-found condition inspection of the EOS housing concluded housing oil seal was not properly seated in one location. Additionally, source of oil was a small seep from upper air start distributor gasket that only occurred with EDG in standby. This gasket was replaced by WO 42996058 (1-25-2017)." R3001S004-022 EDG 14 Emergency Overspeed Switch was replaced per WO 46819697 "Replace EOS switch for EDG 14" on 01/06/2017. 42.307.02, Section 6.18 was performed following EOS replacement satisfactorily. The EOS was sent to Fairbanks-Morse for failure analysis.
 
== Conclusion:==
"oil intrusion into this switch caused a condition where the contacts were unable to make a connection when switch was released. Further, the amount of oil that was contained within switch also contributed to plunger assembly hanging up due to a hydraulic vacuum or lock around plunger, so when engine trip mechanism moved away from the micro switch, plunger did not move back with it so contacts could close. The combination of these conditions from oil intrusion into switch mechanism caused failure of this micro switch." Technical Evaluation TE-R30-17-014 concluded: "loss of EOS would not have prevented engine from shutting down, only prevented opening of the EDG output breaker. There is no impact on lose of EOS because opening of the output breaker would have been accomplished via one of the other engine trip functions such as low lube oil or jacket coolant pressure that also energize shutdown relay (SDR), and open the output breaker." No maintenance rule or safety related functions were lost. Event was not an MSPI failure. Failure of EOS would not have prevented EDG from starting or running while supplying power to its emergency loads. The loss of one of the trips doesn't prevent engine from performing its emergency functions; it only prevents automatic shutdown. Therefore, EDG 14 would have remained operable with the degraded EOS.

Based on the most recent results of Phase 1 and 3 response time testing for the same trip units, 19 msec and 89 msec, respectively, the total response time for the described condition is 276 msec which remains below the total response time allowable value of 1 second (TRM Table TR3.3.6.1-1, Function 1.a).
Therefore, the results of the Phase 2 response time testing being higher than expected does not prevent fulfillment of the specified safety function of Rx Water Level 1 MSIV Isolation. Div 1 Rx Water Level 1 MSIV Isolation Master and Slave Trip Units remain OPERABLE." Two Work Orders are referenced in CARD 16-25547; WO 45758803 and WO 45758812.

CARD 13-28875 states: "During performance of 44.030.401(HPCI/RCIC CST level, E41N061D Calibration/Functional) indication was lost on the H21-P081 Panel Z2 surface. Commenced ARP 2D5 (Testability Div 2 ECCS Logic/Power Failure) and discovered Fuse E41F2B blown. A new fuse was obtained and during replacement sparks, smoke and a small flame were visible coming from Trip Unit E41-N661D. Fuse E41F2B was promptly removed. After a discussion between Operations and I&C, Trip Unit E41-N661D was removed the adjacent cards inspected and Fuse E41F2B was replace successfully. The Z2 surface of H21-P081 was energized. With the Trip Unit E41-N661D removed HPCI and RCIC suction will remain selected to the Torus. CARD Reportability/Operability Review states: "CST Level Instrument E41-N661D is inoperable and tracked on LCO 13-0598. When the fuse blew the following instruments were affected B21N690D, B21N685B, E11N655B/D, E11N656B/D, E21N655B, E21N662B, E41N661B/D and E41N662B/D. The limiting time allowed was 24 Hours per Tech Spec 3.3.5.1, 3.3.5.2 and 3.3.3.1. Operability of these instruments was validated by a channel check following fuse replacement. No loss of safety function occurred during this event. RCIC and HPCI Suction remain aligned to the Torus due to the instrument failure. Investigation determined the cause of open fuse is a failed C25 capacitor on the circuit board on E41N661D HPCI Condensate Storage Tank (CST) Low Level Signal to Suppression Pool Suction Trip Unit. The failed capacitor caused a short and subsequent loss of power. On 6/18/1999, Rosemount made a Part 21 notification to the NRC, Event #35844. The purpose of the notification was regarding a potential need forcapacitor replacement in specific trip/calibration units. Rosemount found that capacitors that were exposed to temperatures and voltages in excess of normal operating conditions have failed. Introduction of contaminant such as moisture could also possibly cause a failure. The affected capacitors have a date code prior to 8630. As a precautionary measure, Rosemount made a component change featuring an enhanced moisture seal. Fermi evaluated this Part 21 notification per CARD 99-15134. The conclusion of this evaluation was to remain with the original C25 capacitors (reasons are listed in CARD). Event was determined to be a MRFF due to non risk significant functions lost on the E11 and E21 systems. E41N661D failure was the initiating event, therefore in accordance with MMR APP D the failure will be counted against E4100.
MRFF was determined to be NOT maintenance preventable. Work Order 37841716 DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                    1-July-2019                                      Page 203 of 270

Review states: "Analog indicator is not used in the calibration of the trip unit nor the transmitter. The indicator is for trending data only. Talked to CARD initiator and only one point was outside ALT - 1200psig (which is above normal operating pressure and above when low pressure systems would be required), all other points were good. This indicator has no impact on the low pressure (ECCS) injection permissive. B21N690D (B21N090D) remains operable." Action Item Completion comments state: "The instrument provides a pressure signal for ECCS response. The isolation logic is 1 out of 2 taken twice as referenced in 23.601, "Instrument Trip Sheets." Each trip channel has 4 instruments that would generate the necessary input to trip thechannel. B21N690D being outside of calibration does not adversely impact the isolation logic because the 3 remaining instruments would generate thenecessary signals to cause the isolation.
Therefore, the function listed above was maintained. No MRFF occurred."

Leaving various other possibilities for a potential cause of this occurrence. Also, reviewed past spurious trips in this string. I&C supervisor consulted with SM and determined to discontinue surveillances on this string until further investigation, and proper risk determinations can be made.
Reportability/Operability Review states: "There was no effect on the relays ability to perform the safety function. Actuation state of A71B-K7D is de-energized to support the safety functions. A71B-K7D relay did de-energize following receipt of the alarm. Half isolation was received during testing, utilizing an N4S test box. this test box jumpered out the A71B-K2D relay string. A71B-K7D did perform as designed, investigation is required into cause of spurious actuation. A71BK7D relay will fully perform its function and is operable but degraded." Troubleshooting package in RF19 produced no new results for cause of spurious half isolation. Previous events and monitoring have concluded that issue lies within the K10D string. WO # 52108126 exists to replace remaining components of K10D string (relay bases and crimp connections for C71K220D, C71K221D, and C71K222D. Next step would be to execute that WO.
Installing an intrusive temporary modification would not provide much value at this time as the issue has been localized to the K10D string. WO 52108126 was generated to perform this work and was attempted to be scope added in RF19 but was not completed.
Recommended that WO be added to next outage as another method of solving spurious half isolation issue.

Both 43.606.001, Traversing In-Core Probe Shear Valve Explosive Charge Test and Replacement Section 7.0 Acceptance Criteria and UFSAR Table 6.2-2 Note 17 support that the explosive charge shall be replaced according to the manufacturer's recommended lifetime for the charge, i.e. prior to the expiration date. Therefore the C5100F001B cannot be relied upon to perform its safety function. The TIP System however is still capable of performing its intended non-safety related function of LPRM calibration with the remaining 4 channels available. TIP B Shear Valve is INOPERABLE. Traversing In-Core Probe (TIP) System remains OPERABLE. TIP B Ball Valve, C5100F002B remained OPERABLE and capable of isolating the penetration, therefore no loss of safety function." MRFF Evaluation was also completed. Justification stated: Since TIP "B" shear valve explosive charge has passed its expiration date, surveillance procedure 43.606.001 'Traversing In-Core Probe Shear Valve Explosive Charge Test and Replacement', work order 27033831, SST event 1981, was performed on 2-20-2014. TIP B squib fired when the keylock switch on the valve control monitor was placed in the fire position and completed the surveillance satisfactory. Since TIP B squib fired, it was able to perform its Maintenance Rule function to isolate containment. Therefore, this is not a Maintenance Rule Functional Failure (MRFF). Since this is not a MRFF, Maintenance Preventable Functional Failure (MPFF) is not applicable. THE DIRECT CAUSE IS PR9 Program/Process Weakness because surveillance procedure 43.606.001 Traversing In-Core Probe Shear Valve Explosive Charge Test and Replacement is adequate, as written. No changes to the procedure are required due to this event. This procedure works well to replace expired squibs before the next refueling outage as long as the date of the refueling outage is not changed. No additional squibs needed to be replaced in RF15 due to expiration date DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                    1-July-2019                                          Page 228 of 270

When RF16 was moved out to 2/2014, the                              TRVEND 24MCGNF319001 Rev 1 critical date for this SST event was verified, but the squib expiration dates were not.                                          Page 342 of 395 There was nothing in place to reevaluate the expiration dates if the outage was moved out to a later date. This deficiency has been corrected by the SST Coordinator being required to review the completed SST event and adjust the critical date of the next SST event based on the earliest expiration date of the squibs. The Corrective Actions are: The SST Coordinator has been added as a post work reviewer to each of the events and will adjust the critical date of the next SST event based on the earliest expiration date of the squibs. This action item addresses cause code PR9 Program/Process Weakness, since the SST critical date will coincide with the earliest squib expiration date and will accurately be reviewed if a future refueling outage is moved out from the original date.

As sequenced now there is pressure locked in suction of HPCI pump which impacts evaluating acceptance criteria in step 5.2.101. When step 5.2.103 is performed there is no question evaluating E4150-F005 check valve in step 5.2.101." 24.202.08 rev 9 DCR 15-0857 made requested change. SPF Note 2: "Step 5.2.172 E4100-F025 failed to stroke within owners specified limit. Second stroke time IAW P&L resulted in same stroke time, 8.3 seconds. CARD 15-26058 submitted" CARD states: "E4100F025, HPCI Cond to DRW OTBD ISO VLV, failed to stroke within Owner specified limit IAW 24.202.08, step 5.2.172. Owner specified limit is 1.9 to 7.3 seconds, valve stroked closed in 8.3 seconds. E4100F025 stroked in 8.3 seconds the second time." Reportability/Operability Review states: "Safety position for E4100F025 is closed and function was proven during surveillance. Slow stroke time does not affect the ability to perform its safety function."
CARD Closure Summary: "Steps were placed in 24.202.01 (Rev. 106) and 24.202.08 (Rev. 8) to stroke time test E4100-F025 on 7/30/15 and 8/3/15 respectively. When Operations ran 24.202.08 on 8/27/15, which is first time stroke time test was performed after baseline measurement was obtained, E4100-F025 failed surveillance acceptance criteria. Direct cause: TESTING (OM3) because stroke time failure was a result of how the test was performed; not degradation. Indirect cause: VERIFICATION PRACTICES (IP11) because IST Program owner did not verify position of test within surveillance.
Test was placed at a step in surveillance that did not match baseline conditions. This happened because Operations lined out step number on SPF and it confused IST Program Engineer. IST Engineer should have gone to tagging center to ask Operations to interpret line out. IST prepared a MMA26 to allow Operations to confirm baseline measurements were collected prior to pump test within surveillance. (See attached).
MMA26 requested that new measurements be collected with HPCI turbine idle. Stroke time measurements, collected prior while HPCI turbine / pump was idle, were found to be nearly identical to baseline average of 4.6 seconds. This confirms original baseline stroke measurements were collected prior to HPCI pump test. This in turn confirms there is no degradation of valve. Revision of 24.202.01(Rev.107) and 24.202.08 (Rev.9) completed. Stroke time measurements are now taken at a step in surveillances that has identical conditions to baseline test.

Reportability/Operability Review states: "This condition has no impact on HPCI performing its intended function nor its operability. The stroke time was re-baselined during RF18, but the surveillance was not revised. The revision came through today and stroke times were verified to be satisfactory. HPCI remains OPERABLE." Action Item Completion Comments state:
                        "The E4100F029 valve and actuator was replaced in RF18 and stroke times changed due to the larger size actuator. The procedure was not updated to included the new stroke times prior to the surveillance." Operations requested that an IST evaluation be performed to revise the surveillance (24.202.08) to help them clear the LCO. IST Evaluation 17-022 was performed on 5/25/17 and was used to revise 24.202.08 (revision 13). IST Evaluation 17-022 concluded that the changes against the reference stroke time were due to the maintenance and that a change to the acceptance criteria was acceptable.
Partial surveillance test was performed to stroke time of E4100-F029 on 5/26/2017 satisfactorily.

                          "CARD 09-22790 documents abnormal indications. TE-R32-09-040 evaluated the condition and determined it to be acceptable." In Step 6.16.1 of SOE 08-05, found an anomaly on top of the black (+) plates of Battery 2B-1. CARD 09-22790 initiated.
CARD 09-22790 states: "Step 6.16.1 of SOE 08-05 performs an inspection of the new battery installed during RF13. A grey material was noted on top of the positive and negative plates during the inspection. This was unexpected. Both the Div 1 and new BOP batteries were inspected and do not exhibit this same anomaly." The CARD goes on to state that a battery representative was dispatched to inspect the condition and determined that the grey material on top of the plates internal to the battery is lead sulfate. The lead sulfate on top of the battery plates will not have an adverse impact on the performance of the battery. In addition to the grey material on top of the plates, some of the cell separators are warped or frayed. Two of the cells (9 and 109) have a white appearance on the side edge of one of the positive (black) plates. Separator material is non-conductive and is used to separate the positive and negative plates from each other to keep them from shorting together. Therefore, any warping or fraying will not prevent the separator from performing its function since this is only seen on the edges of the separator. The last item of interest is the plate straps on a few of the cells do not have a smooth appearance. This is at the top of the cell where the plates transition to the positive or negative posts that extend to the exterior of the battery.

Removed EDG 11 from service IAW 23.307. CARD 14-22612 submitted.                    manually shut down by operators. New CARD 14-22612 states: "While performing LOP/LOCA testing per 24.307.01 (step                design was put on EDG 11 post-fire which 5.1.34 carrying ~1800kW and ~1100 kVAR in parallel with offsite), EDG 11 was                has a flap that covers the seam and manually tripped (locally) due to fire from lagging on the turbo inlet flange area of the    redirects any oils onto the floor away from exhaust manifold.

CO2 from the hand held fire extinguisher. The damage was limited to insulation lagging only. AP-913 CONSEQUENTIAL FAILURE EVENT CLOCK RESET SCREENING determined: This failure would not have resulted in the inability to control a critical safety function (e.g. Reactor water level and pressure, Primary and Secondary Containment, Drywell temperature and pressure, Spent Fuel Pool temperature and level, etc.), or capability to shutdown the Reactor and maintain it in a shutdown condition. The EDG did start and load and was only manually shut down by operators.
This failure is NOT a failure of an MSPI monitored component. Evaluation has shown a reasonable assurance that the fire would have subsided after several minutes and the EDG would have continued to operate. During the investigation on 3/20/14 it was determined a lube oil leak from EDG 11 front engine cover on the control side was seeping through the seam of insulation lagging which accumulated on top of the exhaust manifold under lagging insulation at the control side of the turbo inlet flange area on EDG 11. The accumulation of oil on the exhaust manifold resulted in the fire after the exhaust manifold had heated up during the engine run for surveillance 24.307.01.
Mechanical Maintenance found multiple bolts loose on the front cover of the EDG.
However, after torqueing these bolts the leak was still evident a few hours later. While the engine was in standby a slow drip rate (< 1 drip per 5 minutes) of oil pooled up on top of the four-barrel exhaust inlet to the Control Side (CS) turbocharger from the front engine cover leak. Decision was made to use a sealant to prevent the leak from continuing. Since the front cover is a non-pressurized boundary, and high temperatures (above 250 degrees F) would not be seen, Pro-Seal 34 was used on the seam between the DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                      1-July-2019                                          Page 242 of 270
 
front cover and engine block (WO 38176344). This stopped the leak. Background              TRVEND 24MCGNF319001 Rev 1 Information included with CARD 14-22612 states: CARD 12-29936 was initiated on                        Page 356 of 395 12/12/2012 which identified smoke in the EDG 11 engine room during the monthly surveillance run of the engine. CARD stated most of the exhaust/smoke in the engine room appeared to be coming from under the insulating blanket over the control side 4 barrel exhaust manifold. When the engine is first loaded, exhaust temperatures increase and the oil that is inside or outside of the exhaust manifold burns off. After about 15-20 minutes of loaded engine run time, the generation of exhaust/smoke in the engine room subsides. CARD requested a work order to inspect the EDG 11 control side 4 barrel exhaust manifold for possible cracks and stated it would require removal of the insulation blankets and may require removal of hard insulation (if any exist) under the insulation blankets. Based on the fact exhaust/smoke cleared up after the engine had been loaded, System Engineering stated EDG 11 was able to perform its intended function since the smoke dissipates within 15-20 minutes. CARD 12-29936 Reportability/Operability Review states the smoke/exhaust could be caused by small oil leaks where the oil collects within the insulation and burns off or a small crack on the exhaust manifold. In either case, there is not a concern with EDG 11 being able to meet its intended safety functions as demonstrated by satisfactory completion 24.307.14 operability surveillance. CARD 12-29936 initiated Work Order 35778469 to inspect EDG 11 exhaust manifold to determined cause of smoke and implement corrective action. Work Order 35778469 was coded a priority 5 and was scheduled for an EDG 11 safety system outage (SSO); scheduled during a planned EDG 11 SSO on 1/13/14.
However, the EDG 11 SSO was rescheduled from 1/13/14 to 5/13/14, which was after RF16. Thus, the EDG 11 fire occurred on 3/20/14 during RF16 prior to the new schedule date of 5/13/14 for Work Order 35778469. Stated in CARD 14-22612 Description/Investigation: System Engineering and Operations are used to seeing some smoke during initial operation of an EDG. Due to the design of the engine, some oil will accumulate inside the exhaust manifold from barring the engine over from the previous run. In addition, some oil will enter the inside of exhaust manifold during the initial start of the engine and operation at low load due to the piston rings not having as good a seal allowing some oil to enter the cylinder combustion chamber and then enter the exhaust manifold. When the engine is first loaded to approximately 1750 kW and combined exhaust temperatures increase to approximately 650 degrees F, the oil that is inside or outside of the exhaust manifold normally burns off. After approximately 15-20 minutes of loaded engine run time, the generation of exhaust/smoke subsides. During the engine runs prior to the 3/20/2014 fire, System Engineering had seen more smoke at EDG 11 than on EDGs 12, 13, and 14 when the engine was first loaded to approximately 1750 kW and then saw the smoke clear after approximately 15-20 minutes of loaded engine run time. Thus, even though EDG 11 had more smoke than the other three EDGs, most of the smoke that was at EDG 11 was thought to have been coming from inside the exhaust manifold and leaking out of the exhaust manifold flanges and did not present a fire hazard. Since previous CARD 12-29936 had already initiated Work Order 35778469 to inspect EDG 11 exhaust manifold to determine the cause of smoke and implement corrective action, no new CARDs were initiated by DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                    1-July-2019                Page 243 of 270
 
System Engineering or Operations for the EDG 11 smoke. Because the insulation              TRVEND 24MCGNF319001 Rev 1 lagging on EDG 11 exhaust manifold had not been removed to inspect for possible                        Page 357 of 395 cracks or oil leaks as requested by Work Order 35778469, the risk significance of a fire hazard was not properly understood or challenged by Operations and System Engineering. It is concluded that a higher priority, such as priority 3 or 4, should have been given to Work Order 35778469 by Operations to do the inspection much sooner than the next scheduled EDG 11 SSO. It is expected that completion of Work Order 35778469 would have removed the insulation lagging and allowed the accumulation of lube oil on the exhaust manifold to be found and the source of the oil leak corrected which would have prevented the EDG 11 fire on 3/20/14. From CARD 14-22612, THE DIRECT CAUSE IS M14 - Cause Code: M10 - Mechanical Damage, M19 -
Gasket/O-ring/Seal Failure - A fiber gasket located between the control side of the EDG 11 front cover and the engine block had failed which allowed lube oil to leak and accumulate on top of the exhaust manifold under the lagging insulation and resulted in a fire during a loaded run of EDG 11. The damage was limited to only the lagging.
CARD 14-22612 includes two Apparent Causes which are summarized as follows: 1)
The fiber gasket located between the front cover and the control side of EDG 11 front cover and the engine block failed due to repetitive cyclic compression/decompression that takes place on the gasket during the removal of the top cover of the EDG for its 24 month PM inspections. A 1 1/2 inch section of the front cover gasket was missing. These two conditions resulted in oil leakage from the front cover. 2) Monitoring by plant personnel did not identify a lube oil leak which resulted in an accumulation of oil on top of the exhaust manifold, under the lagging insulation at the control side of the turbo inlet flange area on EDG 11, which presented a fire hazard. Operations did not identify or challenge the risk significance related to CARD 12-29936 initiated on 12/12/2012 and assign the proper priority to the work order for a smoking engine; the lagging was not removed and source of smoke was not identified to determine if a fire hazard existed. Some of the CARD 14-22612 Corrective Actions are: 1) Replacement of lagging insulation blankets on the EDG 11 and EDG 13 exhaust manifolds prior to the turbo on the control side (CS) and opposite control side (OCS) with a different configuration to eliminate the seam that is located right under the corner of the front cover. The new configuration has a flap to divert oil leaks to the floor and prevent oil from leaking into the seam opening and pooling on the exhaust manifold piping. 2)
Tightening of the bolts on the front engine cover and applied an approved sealant to the area of the leak on EDG 11 front engine cover to eliminate the leak that caused the fire until the split front cover could be installed. Also torque checks were performed on the other remaining engine front cover bolts. 3) Replace the one piece front cover with the new split cover design, as well as replacing the front cover gaskets. 4) New technical requirement was added to the 24-month PM to inspect areas around and under front engine cover and front engine cover gasket for evidence of oil leaks. If evidence of leaks are found, replace gasket. 5) Revised maintenance procedure 34.307.001 to perform a torque check on all the engine front cover bolts to verify proper crush of the front cover gasket. 6) Revised PM events W836, W840, W844, and W848 (PERFORM 24 MONTH PM TASKS PER 34.307.001 ON EMERGENCY DIESEL GENERATOR) in Maximo DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                    1-July-2019                Page 244 of 270

Following trip and reclosing of 12EB-EB3 (EDG 12 output breaker) the EDG12 DGSW Pump attempted to start and lost power. This created a situation in which an EDG was running and sequencing on loads with no forced Diesel Generator Service Water. The operating crew tripped EDG 12 using the local overspeed trip. AOPs for loss of 64C and 72C were entered. The operating crew backed out of the surveillance. Bus 64C and 72C have been restored IAW the SOPs. Request investigation and work order to repair."

EDG 12 DGSW pump declared inoperable. LCO 2015-0568." Surveillance 24.307.02 was reviewed to ensure the appropriate conditions were set to close breakers 72EB-2D for EDG12 DGSW and 72EB-2C for Division 1 EESW pump. On 11/21/15 during performance of 23.307.02 a LOCA signal was initiated via Step 5.1.32 & 5.1.33 (CARD 15-29239) to sequence loads on to EDG-12.

was REFURBED in 2009. It was an Extent of Condition position from CARD 09-27133.            TRVEND 24MCGNF319001 Rev 1 The breaker was inspected by Maintenance and no issues were found with the breaker.                    Page 360 of 395 On 11/22/15, WO 44340274 initiated to replace the 72EB-2D breaker with a refurbished/PM'd spare. On 11/23/15 during performance of 23.307.02, Section 5.1 (WO 44349460) of EDG12 LOP/LOCA when a LOCA signal was initiated (CARD 15-29278), Division 1 EESW pump (72EB-2C) tripped immediately after re-sequencing the second time, whereas, EDG-12 DGSW C Pump (R1600S017A, 72EB-2D) re-started as expected. LOR 27X-12EB was observed cycling following the closure of 12EB-EB3.
72EB-2C attempted to close and tripped immediately during load sequencing. The following are other facts from the event:* 27X 12EB LOR Turning on and off (Load Sequence correlates with cycling).* Relay 3NV94 on and off with 27X-12EB by design (Could not confirm other 94 relays).* 72EB-2C did not re-close (closed and re-opened - per video view of breaker lights).* In Relay Room, 12EB light flashed in/out during evolution.

Indications show these are positioned properly.Work order 44346132 "Inspect and Test 27X-12EB, 27-XY, and 27-YZ" was completed. It was determined that the issue was caused by erratic cycling of the LOR 27X-12EB. The relay was replaced and issue was resolved. A failure analysis will be conducted on the LOR 27X-12EB in order to determine the cause of the failure. This CARD will track the failure analysis of LOR 27X-12EB. Failure analysis of LOR 27X-12EB was completed. "Direct Cause found to be inconclusive. Simulation performed wedged a piece of a foreign material behind the trip lever which replicated the original failure. After disassembly of the relay, substance was observed as being drier than normal grease and came off of the lockout relay's internal parts in chunks. The failure analysis led to the conclusion that hardened grease found in the relay could have become foreign material and caused cycling of the relay."
CORRECTIVE ACTIONS: Twenty one PMs were created to replace selected LOR relays (see CARD 15-29239). This CARD action plan is applicable to CARDs 15-29239 and 15-29278. The issues in those CARDs were the result of the failure of LOR 27X-DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                    1-July-2019                Page 247 of 270

Investigation detailed that breaker 72C position 2D feeds non-safety related and non-risk significant distribution cabinet 72C-2D. This failure resulted in the loss of a maintenance rule non-risk significant function and a mode 2 restraint. Breaker is load shed and is not sequenced back on during a LOP or LOP/LOCA. The breaker failed to close after completion of the LOP/LOCA during restoration from the procedure. The breaker was pulled out and troubleshot under WO 44347395. It was found that the x coil (closing coil) had failed which prevented the breaker from closing. The coil was replaced and the breaker was verified to be working properly. The acrid odor indicates that the coil likely shorted. The coil was not saved for inspection. The DIRECT CAUSE E05 - Shorted/Grounded was chosen because the coil failed to create a magnetic field to close the breaker and a smell of burnt electrical insulation was noted.
Investigation noted that Review of work history for this breaker revealed breaker PM had been completed one month prior to the failure. PM indicated the x coil operated as expected. There was no indication of the coil failure that could have been detected. The breaker is refurbished every 8R and the PM is performed every 4R which is in alignment with the industry recommendations. Maintenance Rule evaluation determined because breaker failed to close, it failed to supply power to its load, and therefore, failed function R1400-02, provide power to 4160 VAC and 480 VAC Maintenance Rule Non-Risk Significant loads throughout the plant. The breaker was opened which successfully allows it to perform its function of protecting bus 72C. Therefore function R1400-01, was not lost. The PM work order, 34484681 (i.e., completed one month prior to the failure) was reviewed to determine if there was any indication of the x coil being degraded. The x coil operated as expected at 80% rated voltage (the requirement is 95%)
and the minimum megger value was greater than 550 meg-ohms. There was no indication of binding discovered during the PM or the investigation WO and the breaker was cycled for PMT at the end of each WO. There has also been no history of issues associated with this breaker serial number. Maintenance on the breaker is performed in accordance with all known industry and vendor recommendations which include the coil acceptance criteria for determining if the coil is degraded. The industry does not recommend periodic replacement of the closing or trip coils as most pending coil failures can be caught by the testing during the PM. There was no indication of the coil failure that could have been detected." As noted: "Sys Engineering- 01/28/2016 08:43:04 AM To address managers comments. This CARD gives an inappropriate level of perceived component importance due to an improper selection of MR function during the initial MRFF evaluation. The actual function lost was non-risk significant and this CARD should have only been made a Level 3. This error in the MRFF evaluation will be corrected during the update from L1-pending investigation. The failed coil was not kept for any failure analysis. As discussed in the CARD body, the PMs are consistent with the DTE-19001, Rev. 1 --Fermi 2 Technical Specification Event Failure History Evaluation                      1-July-2019                                          Page 248 of 270

CARD 10-21400 states: "...an unexpected                    that were expected to be closed and were resistance was detected in the E51-K20 (E5100M020) relay.

This condition affects the ability of the E5150F013 to close on a RCIC Turbine trip          Therefore, this failure will have no impact signal." Cause of the failure is stated as follows: "Surface contamination on relay          on an extension to a 24 month surveillance contact surfaces is expected and unavoidable (tarnish and dust). The wiping action of the    interval.
relay is typically sufficient to remove these contaminates. However, stubborn contamination may not be removed during the first few wipes of the relay. Depending on the level of contamination, different test devices will indicate different levels of resistance. The surveillance utilizes a Fluke VOM for resistance determination in this surveillance. Since the VOM only applies small currents through the contacts being tested the current level may not be sufficient enough to pass through even minor contamination. This would result in a high calculated resistance reading, which can be construed as a failed surveillance. If a different meter with a stronger current source is used, minor contamination does not present sufficient resistance to the current flow and the calculated resistance will be lower. The minor surface contamination does not prevent the relay contact from performing its intended function because in the logic chain, the contacts carry high enough currents to overcome this minor resistance.

To determine if the relay had truly failed its surveillance, a bench test was developed to test the relay contact resistance at rated power and loads. Bench test results indicated that the relay contact 3-4 would have worked as required. Therefore, the in-situ testing of the relay with a fluke meter is very conservative due to low voltage and may allow for a false failure to be concluded for a relay contact."

Perf. Date Fail Cat. Description of Failure                                                                          Justification of Failure 11/24/2010      A      SPF notes four issues: 1) "Step 6.4.10.2.a and b. No Closed lights. See WO 29748936, All three valves were able to perform the switches were adjusted and retest was SAT." WO 29748936 was written (4/27/09) in              intended safety function. The identified support of CARD 09-23281 (written 4/26/09). CARD 09-23281 states: "B31-F506A                  failure(s) would not have prevented the Excess flow check valve has no indication .

WO 29748936 was                  of the equipment. Therefore, this failure will completed on 11/24/2010 to adjust limit switches satisfactorily. 2) "Step 6.5.11.2.a & b., have no impact on an extension to a 24 no closed lights also Step 6.5.11.4.

New CARD 10-31289." WO 29748902 was written in support of CARD 09-23249 (written 4/25/09). The Corrective Actions stated in CARD 09-23249 are: "Work order 29748902 initiated to replace B31-F503B in RF14. Work order is included in RF14 potential scope and also included on the B3100 System Health Report as a targeted milestone to return system health to GREEN." During this performance of 44.220.110, WO 29748902 was revised as stated: "The original scope of this work order was to replace Excess Flow Check Valve B31-F503B due to its poor maintenance history, a replacement valve could not be received in time for RFl4 so it is desired to fix only the dual indication at this time. The purpose of this work order is to replace the limit switches for B31-F503B and to adjust limit switches for proper indication. NOTE: This work request is written to utilize 18 month surveillance 44.220.110 to establish initial conditions, perform testing and calibration, and to restore and IV instruments back to service." WO 29748902 was completed as revised satisfactorily. New CARD 10-31289 (written for this 11/24/2010 event performance) Description/Investigation states:
                        "B31F503B has been worked every refuel outage since RF8 except for RF10. The original plan for RF14 was a complete valve replacement. The work package was planned in January 2010 and the EFCV was ordered by the planner. The part did not arrive for RF 14 because there was a discrepancy between the vendor and the item master number. The part was never ordered due to this discrepancy. We knew going into RF14 that we were not going to be successful, but we had a commitment to attempt to repair the indication. A new Work Order was generated for RF15, the WO number is 32174694 and the EFCV was ordered by the planner."

Summary states: "The Vendor discrepancy was cleared up and a new PO was created for                          TRVEND 24MCGNF319001 Rev 1 the Work Order in RF15." CARD Reportability/Operability Review states: "B31F503B,                                        Page 373 of 395 Recirc Loop B flow instrumentation EFCV, is a PCIV. During the RPV pressure test the B31F503B demonstrated isolation function by closing as demanded. B31F503B remains operable as a PCIV." CARD Description/Investigation details that: " The valve is closing properly and passes the Closing Functional exam (Step 6.6.11.2.c) in 44.220.110. The valve will successfully close on demand to satisfy it's safety function. It is evident the valve is currently open - providing it's function as a source valve for Recirc Flow instrumentation." 3) "Step 6.5.11.6.a & b. and 6.5.11.7, no open lights.

6.3.10, 3 to re-calibrate G11-K603 integrator. This is due to the fact that any calibration of the loop components can change the tolerance of the integrator which is acceptance criteria. Reportability/Operability Review states: "The drywell sumps are used for leakage monitoring. The Drywell Equipment Drain Sump level, flow and pump run time integrators are used to determine changes in identified leakage in the drywell. The Drywell Equipment Drain Sump Effluent Flow integrator is the instrumentation used to meet the TRM requirements. All ACCEPTANCE CRITERIA associated with the flow integrator were met. The flow indication on the G11R600 is not used for determining DW leakage rates, and is not a required indication. The Drywell Equipment Drain Sump level, flow and pump run time system remains OPERABLE." Also noted Reportability/Operability Review is: "The flow recorder point is outside of the Leave Alone Tolerance (LAT) only for the 100% (125 gpm) calibration point. It is within the LAT for all calibration points (100 gpm and below). The normal operating range when the equipment drain sump is pumped is below 100 gpm. So, the MCR flow indication remains accurate for the ranges that the system normally operates." Review of the CARD and of the affected procedure was performed; I&C procedure writer concurred the requested changes should be implemented using a DCR. DCR 18-1780 was initiated.

CARD Cause: "The Direct Cause was: Degraded CT. This was the only change to the circuit since successful completion of the circuit. The Apparent Cause is Abnormal Electrical Stress from a loose connection/open circuit in RF17 (CARD 15-28495). The open circuit of the CT in RF17 could have developed high voltages and degraded the CT. This degradation cannot be detected at low current test conditions. Due to the fast acting relaying the high voltages may not have been long enough in duration to cause a complete failure of the CT. A Contributing Cause is Degradation of the 87 relay time delay. Original manufacture time delay curve states the relay should actuate between 14 and 38 milliseconds and should be around 30 at the test values utilized by Fermi. The 87 relay is actuating at 8 milliseconds. Cause Code E01-Setpoint Drift. Corrective Actions: DC/AC-Replace the affected CT's at 72C-F MCC completed. CC-Replace the 87 relay with a relay including a time delay per ERE-44596 - completed. The extent of the apparent cause is limited to CT's that have been open circuited. There is one other known occurrence in which a CT was open circuited. This was the failed knife switch in the 345KV relay house coming out of RF17. This CT has been operated throughout the last cycle in the range it is expected to operate at and has not shown any degradation. The extent of the contributing cause is limited to the 50 and 87 relays in the 72C-3C circuit. The model relay was not found used in any other locations. The 50 and 87 relays were replaced under ERE-44596. This failure was determined to be a Functional Failure as when breaker 72C, position 3C tripped unexpectedly this resulted in inability of the breaker to supply power to MCC 72-CF which is a risk significant load.

It was determined that the issue was caused by erratic cycling of the LOR 27X-12EB. The relay was replaced and issue was resolved. A failure analysis will be conducted on the LOR 27X-12EB in order to determine the cause of the failure. This CARD will track the failure analysis of LOR 27X-12EB. Failure analysis of LOR 27X-12EB was completed. "Direct Cause found to be inconclusive. Simulation performed wedged a piece of a foreign material behind the trip lever which replicated the original failure.
After disassembly of the relay, substance was observed as being drier than normal grease and came off of the lockout relay's internal parts in chunks. The failure analysis led to the conclusion that hardened grease found in the relay could have become foreign material and caused cycling of the relay." CORRECTIVE ACTIONS: Twenty one PMs were created to replace selected LOR relays (see CARD 15-29239). This CARD action plan is applicable to CARDs 15-29239 and 15-29278. The issues in those CARDs were the result of the failure of LOR 27X-12EB.

CARD Cause: "The Direct Cause was: Degraded CT. This was the only change to the circuit since successful completion of the circuit. The Apparent Cause is Abnormal Electrical Stress from a loose connection/open circuit in RF17 (CARD 15-28495). The open circuit of the CT in RF17 could have developed high voltages and degraded the CT. This degradation cannot be detected at low current test conditions. Due to the fast acting relaying the high voltages may not have been long enough in duration to cause a complete failure of the CT. A Contributing Cause is Degradation of the 87 relay time delay. Original manufacture time delay curve states the relay should actuate between 14 and 38 milliseconds and should be around 30 at the test values utilized by Fermi. The 87 relay is actuating at 8 milliseconds. Cause Code E01-Setpoint Drift. Corrective Actions: DC/AC-Replace the affected CT's at 72C-F MCC completed. CC-Replace the 87 relay with a relay including a time delay per ERE-44596 - completed. The extent of the apparent cause is limited to CT's that have been open circuited. There is one other known occurrence in which a CT was open circuited. This was the failed knife switch in the 345KV relay house coming out of RF17. This CT has been operated throughout the last cycle in the range it is expected to operate at and has not shown any degradation.
The extent of the contributing cause is limited to the 50 and 87 relays in the 72C-3C circuit. The model relay was not found used in any other locations. The 50 and 87 relays were replaced under ERE-44596. This failure was determined to be a Functional Failure as when breaker 72C, position 3C tripped unexpectedly this resulted in inability of the breaker to supply power to MCC 72-CF which is a risk significant load.

(note: also saw this a few times Saturday 11/21/2015) This is the XK31 indicating light on drawing I-2714-22. This is lit from 12EB Load Shed Relay 2MR69 (Drawings I-N-2572-18 Grid D-7, B-7 & I-2714-22).* EDSW restarted as expected (see video).* EESW tripped today AND Saturday (see pump flow curves).* Checked Potential Transformers (PT); circuits good.*
Check EB3 52S and 52H cell switch. Indications show these are positioned properly.Work order 44346132 "Inspect and Test 27X-12EB, 27-XY, and 27-YZ" was completed. It was determined that the issue was caused by erratic cycling of the LOR 27X-12EB. The relay was replaced and issue was resolved. A failure analysis will be conducted on the LOR 27X-12EB in order to determine the cause of the failure. This CARD will track the failure analysis of LOR 27X-12EB. Failure analysis of LOR 27X-12EB was completed. "Direct Cause found to be inconclusive. Simulation performed wedged a piece of a foreign material behind the trip lever which replicated the original failure. After disassembly of the relay, substance was observed as being drier than normal grease and came off of the lockout relay's internal parts in chunks. The failure analysis led to the conclusion that hardened grease found in the relay could have become foreign material and caused cycling of the relay." CORRECTIVE ACTIONS: Twenty one PMs were created to replace selected LOR relays (see CARD 15-29239).
This CARD action plan is applicable to CARDs 15-29239 and 15-29278. The issues in those CARDs were the result of the failure of LOR 27X-12EB.

accomplish this. CARD 17-23496" CARD 17-23496 states: "Drywell Cooling Fan 12 did not restart during the load sequence following simulated loss of power. Reference Acceptance Criteria Step 5.1.17. The CMC switch for T4700C012 was in Auto and indicated TRIPPED upon attempted restart. A couple minutes later all indications were lost at the CMC switch. Field walkdown found an acrid odor at MCC 72E 5B. The MCC was deenergized and initial investigation shows indication of a burnt contactor. Investigate cause and repair." CARD Reportability/Operability Review states: "72E-5B was de-energized following the failure, to de-energize the MCC for Drywell Fan #12.
The inoperability is tracked on LCO 2017-0210. 24.307.03 was backed out of, with only part of Section 5.1 complete." Investigation by electrical maintenance and operations found the contactor coil burnt. The Direct Cause is E04 -
insulation breakdown because the coil insulation broke down and shorted resulting in the inability to close the contactor and start the drywell cooler. WO 47495796 initiated to replace contactor. A replacement contactor (i.e., 2 Overload blocks and Aux contact block) was installed and DWC #12 operated as expected.
