Docket 50-271 BVY 09-009 Attachment 1 Technical Specification Proposed Change No. 273, Supplement 7 Vermont Yankee Nuclear Power Station Response to Request for Additional Information

BVY 09-009 / Attachment I/page I of 5 Technical Specification Proposed Change No.273, Supplement 7 Vermont Yankee Nuclear Power Station Response to Request for Additional Information RAI No.1 The licensee should docket the correction of the reference from the Instrumentation Uncertainty and Setpoint Design Guide, Revision 2, submitted July 21, 2003 (ADAMS Accession No. ML032130568), to Revision 3, submitted December 11, 2003 (ADAMS Accession No. ML033510764).

Response to RAI No. 1 The appropriate version of the Setpoint Design Guide, that is applicable to this proposed change, is Revision 3 which was submitted to the NRC on December 11, 2003 in Entergy Nuclear Operations Letter BVY 03-115.

RAI No.2 The licensee should confirm that with the changes proposed in the letter dated February 12, 2008 the CTS setpoint philosophy, as depicted in Figure 5, on pages 47 of 75, in the Instrumentation Uncertainty and Setpoint Design Guide, Revision 3 is still maintained for all setpoint changes in this amendment request.

Response to RAI No. 2 For the set-point changes provided in the letter dated February 12,2008 (BVY 08-001), the CTS setpoint philosophy, as depicted in Figure 5, on pages 47 of 75, in the Instrumentation Uncertainty and Setpoint Design Guide, Revision 3 is still maintained for all setpoint changes in this amendment request.

RAI No.3 For each setpoint change identified in Response to RAI No. 1, in the letter dated December 18, 2008, the licensee should identify the setpoint class (as defined on pages 2 thru 5 of 75 in the Instrumentation Uncertainty and Setpoint Design Guide, Revision 3).

Response to RAI No. 3 All setpoints identified in the letter dated December 18, 2008 (BVY 08-087) are Class 1 setpoints.

BVY 09-009 / Attachment I/ page 2 of 5 Technical Specification Proposed Change No.273, Supplement 7 Vermont Yankee Nuclear Power Station Response to Request for Additional Information RAI No.4 In Response to RAI No. 2, in the letter dated December 18, 2008, the licensee stated, "None of the setpoints proposed to be modified by this submittal are LSSS setpoints."

Included in the setpoints to be modified is TS Table 3.2.1, Emergency Core Cooling System (ECCS), Trip Setpoint 3.b, "High Pressure Coolant Injection (HPCI) System Low Condensate Storage Tank Water Level." The staff has a concern that this setpoint should be considered Limited Safety System Setting (LSSS) Safety Limit (SL)-related.

Part of the basis for this concern is that the Vermont Yankee UFSAR 1.6.2.11.1 states, "The HPCIS provides and maintains an adequate coolant inventory inside the reactor vessel to prevent fuel clad conditions from exceeding 10 CFR 50.46 criteria as a result of postulated small breaks in the nuclear system process barrier." UFSAR 6.4.1 states, "The HPCI System is provided to assure that the reactor core is adequately cooled in the event of a small break in the nuclear system and loss of coolant which does not result in rapid depressurization of the reactor vessel simultaneous with a loss of normal auxiliary power." UFSAR 7.4.3.2.1 states, "When actuated, the HPCI System pumps water from either the Condensate Storage Tank (CST) or the Suppression Chamber to the reactor vessel via the feedwater pipelines."

Paragraph 50.36(d)(1)(ii)(A) of 10 CFR Part 50 states that where an LSSS is specified for a variable on which a safety limit has been placed, the setting must be so chosen that the automatic protective action will correct the abnormal situation before an SL is exceeded.

These SLs are designated SL-related LSSSs. Appendix A to 10 CFR Part 50 defines AOOs as those conditions of normal operation that are expected to occur one or more times during the life of a nuclear power unit.

Vermont Yankee TS 1.0 specifies the SLs for the plant. The NRC staff evaluated the Condensate Storage Tank level-low setpoint for HPCI to determine if it should be considered as SL-related. The SL of concern is TS 1.1 .D which requires that the reactor vessel water level shall not be less than 12 inches above the top of the enriched fuel.

The licensee should describe how the Condensate Storage Tank, HPCI System, and other systems are used to assure that the reactor vessel water level is above the top of the enriched fuel.

The licensee should also detail any components in these systems that are not safety grade and what safety grade systems are credited to ensure the SL.

Does the Condensate Storage Tank contain sufficient volume to ensure that the reactor water level SL is not exceeded without the switchover to the suppression pool?

Based on the March 3, 2009 conference call with Entergy to discuss the Vermont Yankee instrumentation setpoint issues, the licensee was going to review the Technical Specifications Task Force (TSTF) letter to the NRC, dated February 23, 2009, "Industry Plan to Resolve TSTF-493, Clarify Application of Setpoint Methodology for LSSS

BVY 09-009 / Attachment I/page 3 of 5 Technical Specification Proposed Change No.273, Supplement 7 Vermont Yankee Nuclear Power Station Response to Request for Additional Information Functions," (ML090540849). Upon review of the TSTF letter, the licensee will determine how they want to approach resolution of the staff's concern about LSSS SL-related setpoint changes.

If the licensee intends to add footnotes based on adoption of Strategy 2, on page 3 of the TSTF letter (the addition of footnotes for functions identified in the TSTF letter) the licensee should provide the proposed footnotes, a summary calculation, and a copy of the surveillance/calibration procedure, for the proposed revised setpoint for Vermont Yankee TS Table 3.2.1, "Emergency Core Cooling System (ECCS)," Function 3.b, "High Pressure Coolant Injection (HPCI) System Low Condensate Storage Tank Water Level."

This function is included in Attachment A, of the TSTF letter, on page A-9, Specification 3.3.5.1, "Emergency Core Cooling System Instrumentation," Function 3.d, "HPCI System Condensate Storage Tank Level - Low."

A sample setpoint calculation for RCIC System High Steam Line Space Temperature Isolation setpoint was submitted with the licensee's December 18, 2008 letter (ML083650007). However, this sample calculation is not applicable for the HPCI System Low Condensate Storage Tank Water Level setpoint.

Therefore, the licensee should submit a summary calculation for HPCI System Low Condensate Storage Tank Water Level that includes the Analytical Limit, Total Loop Uncertainty, how the Nominal Trip Setpoint was calculated, how the acceptable As-Left value was calculated, and how the acceptable As-Found value was calculated. The entire calculation is not needed, only a summary calculation.

The licensee provided a description of their surveillance/calibration procedures in the December 18, 2008 letter. The staff's understanding of the description is: The surveillance/calibration procedures list the as-left and as-found calibration tolerances. If the as-found value is within the as-left tolerance, the technician documents that no action is required and the equipment is returned to service. If the as-found value is outside the as-left tolerance, but within the as-found tolerance, the condition is documented, a general conditions inspection is performed, and the equipment is calibrated and returned to service. If the technician does not identify any degradation during the calibration, the equipment is considered operable and returned to service. If the as-found value is outside the as-found tolerance, the equipment is entered into the Corrective Action Program.

However, the licensee's description of their surveillance/calibration procedures did not include a discussion of the plant corrective action process for declaring a channel inoperable when the as-found value is outside the as-found tolerance and for restoring a channel to operable status when the channel has been determined to be inoperable.

Therefore, the licensee should provide a description of the surveillance/calibration procedures that (1) includes a discussion of the plant corrective action process for restoring a channel to operable status when the channel is determined to be inoperable and (2) address investigations of why an as-found value drifted outside the as-left tolerance. The licensee should also describe what the general conditions inspection includes.

BVY 09-009 / Attachment I/ page 4 of 5 Technical Specification Proposed Change No.273, Supplement 7 Vermont Yankee Nuclear Power Station Response to Request for Additional Information For each setpoint change in which footnotes are being added to the TS (HPCI System Low Condensate Storage Tank Level), a copy of the surveillance/calibration procedure should be submitted for information purposes.

Response to RAI No. 4 Based on a telecom held on March 3, 2009, Vermont Yankee (VY) proposes to add the footnotes provided in industry TSTF-493, Revision 3, "Clarify Application of Setpoint Methodology for LSSS" to proposed Technical Specification (TS) Table 3.2.1 "Emergency Core Cooling System Instrumentation" for function 3.b, the High Pressure Coolant Injection (HPCI)

System Low Condensate Storage Tank (CST) Water Level setpoint.

The HPCI system works in conjunction with the other Emergency Core Cooling Systems to ensure that 10CFR50.46 requirements are satisfied. The HPCI system and CST components that support this function are safety related. The HPCI system relies on both the CST and the suppression pool to perform required safety functions. provides the proposed changes to the TS and an associated TS Bases change.

The TS Bases change is provided for information only.

As requested, Attachment 3 provides the applicable portions of the related setpoint calculation.

As requested, copies of the related calibration procedure (OP 43*63) and the plant procedure governing surveillance and calibration activities (AP 0310) are included as Attachment 4. A summary of how these procedures interface with the corrective action program and operability is provided below.

VY TS provide a six hour window for the performance of instrument calibrations without entry into the associated TS Limiting Condition for Operation (LCO). Prior to performing an instrument functional test or calibration, the Operations Department Shift Manager is informed of the activity and grants permission to proceed. Upon completion the Shift Manager is notified of the test results and any discrepancies. This ensures that the Shift Manager is aware of any issues that could impact operability and result in the need to be entered into the Corrective Action Program (CAP).

During the instrument calibration if a component is found outside the prescribed as-found range the result is "circled in RED" and brought to the attention of the technician's supervisor and Shift Manager as discussed above. An evaluation of the as-found condition on operability is performed and, if necessary, an LCO is entered. Once entered, the LCO would not be exited until corrective actions are taken that restore operability. This evaluation is documented in the related CAP report which is initiated to trend the occurrence and further investigate and determine if additional corrective actions are required. The evaluation would include an assessment of the as-found condition on the instruments ability to properly perform its intended function and a general condition inspection of the instrument for obvious material conditions that could impact component functionality.

BVY 09-009 / Attachment I/ page 5 of 5 Technical Specification Proposed Change No.273, Supplement 7 Vermont Yankee Nuclear Power Station Response to Request for Additional Information Following approval of the proposed change, Entergy will enhance procedures to incorporate the specific wording associated with the proposed footnotes and to define expectations for performance and documentation of the required evaluation.

Amendment No. 4-4 40

BASES 3.2A/4.2A Emergencv Core Cooling System (ECCS)

Table 3.2.1 ACTION Notes 9 and 10 The Emergency Core Cooling System Instrumentation, High Pressure Coolant Injection, Low Condensate Storage Tank Water Level function is modified by Notes 9 and 10 as identified in Table 3.2.1. Note 9 requires evaluation of channel performance for the condition where the as-found setting for the channel setpoint is outside its as-found tolerance. Evaluation of channel performance will verify that the channel will continue to behave in accordance with safety analysis assumptions and the channel performance assumptions in the setpoint methodology.

The ability to reset the setpoint represents continued confidence that the channel can perform its intended safety function. The performance of this channel will be evaluated under the Corrective Action Program. This will ensure required review and documentation of the condition for continued operability. Note 10 requires that the as-left setting for the channel be returned to within the as-left tolerance of the Nominal Trip Setpoint. Where a setpoint more conservative than the Limiting Trip Setpoint is used in the plant surveillance procedures, the as-left and as-found tolerances, as applicable, will be applied to the surveillance procedure setpoint. This will ensure that sufficient margin to the Safety Limit and/or Analytical Limit is maintained. If the as-left channel setting cannot be returned to a setting within the as-left tolerance of the Nominal Trip Setpoint, then the channel shall be declared inoperable. The methodologies for calculating the Nominal Trip Setpoint and the as-left and the as-found tolerances are located in the Vermont Yankee Setpoint Program Manual which is included by reference in the UFSAR. This ensures changes are evaluated under IOCFR50.59.

CST water minimum temperature is maintained Ž_50 OF (as read on Ti-1 07-3) per VY Procedure AP-0150, Auxiliary Operator Round Sheet TB/OUT, page 5 of 7 (Attachment M). The tank is heated by auxiliary steam heating coils. As a

conservative value for minimum temperature, the assumed value of 40°F froimn FSAR section 14.5.2 will be used [Ref. 6.2].

CST water maximum temperature is assumed equal to the maximum ambient temperature of 100 'F as identified in FSAR section 2.3.5 and on HPCI Process Diagram 5920-0784 [Ref. 6.29.1].

2.3.3. The calibration interval is assumed to occur once every quarter or 114 days (91.2 days + 25%).

2.3.4. The transmitter loops are calibrated quarterly and the test equipment temperatures will be bounded by the ambient temperatures extremes listed in Table 2 above. For the test equipment uncertainty evaluations performed under VYC-1 758 [Ref. 6.9, Attachment K], the RB RHR Cmr Rm 232' environment conservatively bounds the environment to be expected at the CST instrument room, and will therefore be used as representative of the CST instrument room.

2.3.5. The temperature variation within a cabinet is the same as the variation of the room in which it is located. The temperature difference between the room and the cabinet is therefore constant. Calibration data are assumed collected with the equipment at the operating temperature of the cabinet.

2.3.6. Review of the Vermont Yankee Environmental Qualification Program Manual (Ref. 6.7] indicates that none of the loop components covered by this calculation is environmentally qualified and are therefore only expected to operate under mild conditions, and negligible radiation exposure. Other than the pressure transmitters located at the tank enclosure, all loop components are located in the control room.

2.3.7. Calibration Tolerance is an output of this calculation, and will be based on the accuracy of the devices. The existing calibration tolerances shown in Tables 5 through 10 are for information only.

a) The analyzed drift data shows the 50% point to be the largest value at 1.2237% with the 0% value at 1.0625%, and the 100% point at 1.0604%.

The 50% analyzed drift value.is largest, and will be used as a conservative ddft value.

b) From review of this drift analysis and the histograms, the data exhibits a near-normal distribution for all points. As indicated in the time dependency discussion for the OP-4363 CST Level Computer Point Loop (Attachment L), some time dependency is exhibited at the 100% point However, the Significance F at all points is much greater than 0.05, indicating no correlation between drift magnitude and time interval. Since there is no indication of a drift to time relationship, the 114-day Analyzed Drift Term will be derived directly from the 82-day ADR term.

c) The average drift value for this group is -0.2293% at the 100% point, -

0.2163% at the 50% point, and --0.1580% at the 0% point. Since these values are all more than 0.08% (N *<40 and STDEV k 0.25%), this term must be considered as a significant bias term [REF. 6.11].

5.2.1. Current Low Level Suction Transfer setpoint As evaluated in Attachment D, section 5.2. the existing Low Level suction transfer setpoint of 12.1 mVdc cannot be supported based on the new requirements for critical height of submergence of the HPCI suction. The revised Process Limit of 2_28.2" from CST bottom [Ref. 6.10 and Attachment C]

includes consideration for the TS requirement that the setpoint be > 3% and that there be 10,000 gallons reserve at the suction transfer point See Table 13 below.

5.2.2. Revised Low Level Suction Transfer setpoint A revised setpoint is evaluated in Attachment D, section 5.3; the proposed setpoint of 12.2 mVdc decreasing supports the requirements for critical height of submergence of the HPCI suction + 10,000 gallon reserve and has adequate margin from LSP to SP. See Table 13 below.

Table 13 Setpoint Results

5.3. Calibration and Test Results In order to support and implement the results of this calculation, the loop instruments are to be calibrated at nine points based on the following ranges:

10 Referenced to tank bottom.

1 As sensed by transmitter, level above transmitter tap (0") plus 4' static head.

PURPOSE To provide Instrument and Control Department personnel with approved methods of functionally testing the HIPCI suction valves auto transfer, calibrating the CST level transmitter loops and calibrating other associated CST level instruments.

Performance of the Functional section of this procedure satisfies the Functional Test requirements as specified by the following Technical Specifications:

Table 4.2.1 for the HPCI Low Condensate Storage Tank Water Level.

Performance of the Calibration section of this procedure satisfies the Calibration and Functional Test requirements as specified by the following Technical Specifications:

Table 4.2.1 for the HIPCI Low Condensate Storage Tank Water Level.

DISCUSSION The CST level transmitters and associated loop instruments provide information on water level in the CST. This level information is used to automatically shift the HPCI suction valves from the CST to the torus in the event of a low CST level signal, provide level indication in the Control Room and provide CST low level and instrument loop trouble annunciation in the Control Room.

Additionally, CST Hi and Low level pressure switches and a local indicator are also tapped off of the sensing lines to the transmitters and are calibrated per this procedure.

Calibration of these instruments do not satisfy any T.S related surveillance.

This procedure shall be accomplished by using Measuring and Test Equipment to inject pressure signals as required for the instrument(s) being tested.

The CST water level instruments tested by this procedure are listed in Table 1 below.

Calibration of LSH-107-6, LSL-107-7 and LI-107-6 is not being performed as part of any Technical Specification requirements.

The level transmitter has a positive 4" H2 0 head applied at all times due to the transmitter being located below the instrument tap. The tap is located at an elevation of 254' and the transmitter centerline is located at 253'8".

To assure consistent performance of work activities the referenced procedures are to be used as applicable and the proceeding processes are to be followed when appropriate.

Safety requirements will be complied with during all work activities.

AP 0310 Rev. 20 Page.6 of 24

4.4.1. Surveillance Test Time Monitoring During performance of Tech. Spec. surveillances which have a 6-hour allowance for performance of the surveillance without entering the LCO actions, it is the I&C Specialist's responsibility to monitor the performance time and to notify the Shift Manager as soon as it is identified that the 6-hour allowance may be exceeded.

When recording elapsed time (stop-start), rounding up to the next hour is acceptable for times up to 5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months . For example, 43 minutes can be recorded as <1 hour.

4.4.2. Independent Verifications When independent verification of a component or condition is required and circumstances require two individuals to work together, the act of independent verification must be completely separate and independent. The verifier must not rely on the observed action (except in Steps 4.4.2.1 and 4.4.2.2 below) of a co-worker to determine component identification, position, or condition. Actual separation of workers is not required, but is recommended when practical. The key element is independent assurance of the described condition.

4.4.2.1. When checking the position of a throttled valve or torquing of a component (for example), it is unreasonable to expect a second manipulation, In these cases, the independent verifier would clearly observe the first checker's manipulation of the device.

4.4.2.2. In cases involving significant radiation exposure, the department supervisor may determine the appropriate form of verification and so note it on the documentation.

4.4.3. Second party verification Second party verification is when the second individual verifies that the original performer is accomplishing/performing the activity correctly. The normal process for this is as follows.

4.4.3.1. The second party verifier will observe the performer identify the component, position, or condition.

4.4.3.2. If the second party verifier does not agree with the component, position, or condition, this discrepancy will be pointed out for clarification and resolution. No activity should be performed until both parties are in agreement.

4.4.3.3. The second party verifier will actively observe the performer complete the activity.

4.4.3.4. After the activity has been performed, the second party verifier will sign off indicating acceptability.

AP 0310 Rev. 20 Page 7 of 24

4.4.4. Procedure Signoffs When performing a surveillance or calibration it is not always practical to have all persons involved sign one procedure during the activity. In these situations the following protocol shall be followed.

4.4.4.1. All individuals involved with the activity will have a copy of the procedure.

4.4.4.2. Communications will be maintained during the activity.

4.4.4.3. Individuals performing a step will sign the copy in hand.

4.4.4.4. Verification through communication will be made of step completion before proceeding to the next step.

4.4.4.5. Upon completion all signatures will be transferred to one master copy of the procedure.

4.4.5. When performing a multi-component procedure for only one component the person performing test shall place a N/A next to the remaining component numbers with an explanation in the Remarks/Discrepancy section of the Data Sheet.

4.4.6. If during the work activity a problem is encountered with the procedure the requirements of AP 0095 shall be complied with to stop work at a safe point and notify department supervision for assistance to correct the problem. Procedures will always be used in concert with data sheets.

4.4.6.1. At times during the performance of procedures, plant conditions will prevent or mask a response expected in the procedure. When this occurs, the department supervisor is to be contacted. The department supervisor, with concurrence from the Maintenance Support group, may authorize the procedure to continue with an exception taken for the specific response. All exceptions taken and the reason for the exception shall be noted in the Discrepancies/Remarks section of the procedure. An ER shall be generated per AP 0009 for any procedure that can not be completed as written.

4.4.7. When surveillance procedures are to be performed over a number of days the date of actual component completion will be documented in the procedure and the shop surveillance list.

4.4.8. Environmentally Qualified Equipment When work is performed on EQ equipment it is essential that any changes be documented or that the component is returned to its original qualified condition. The following procedures are established to ensure compliance with the code requirements and must be referenced as applicable.

4.4.8.1. AP 0092, used for changes or supplemental clarification to EQ program manual.

AP 0310 Rev. 20 Page 8 of 24

4.418.2. AP 0021, describes the process of WO review and actions to take as necessary.

4.4.8.3. AP 0305, provides guidance and establishes a mechanism for the maintenance of I equipment qualification files.

4.4.9. Adjustments/Alterations Tolerances are established based on balancing the necessity to prevent violations of design limits and the reduction of adjustments required. At times it may be prudent to optimize the calibration prior to the instrument exceeding the specified tolerance.

4.4.9.1. Functional Calibrations If during a functional calibration it is identified that the instrument is in tolerance but may need to be adjusted the supervisor shall be informed. Based on available information the calibration section of the procedure may be entered to optimize the readings. The following shall be used to identify test results.

AS-FOUND data which is out of tolerance or adjustments made per the above supervisors determination are to be circled in RED.

AS-LEFT data which is out of tolerance is to be circled in RED and documented in the discrepancy section of the data sheet or on the data page of the PM work order and brought to the attention of the supervisor.

IC Supervisor will evaluate As-Left condition and advise the Department Superintendent and Shift Manager of any Out of Service condition.

AP 0310 Rev. 20 Page 9 of 24

4.4.9.2. Other Calibrations NOTE It is preferred that all instruments are returned to the cardinal point if the adjustment is easily done. Instruments within thetolerance range are considered to meet the minimum requirements. Concerns should be brought to the supervisor's attention.

If not delineated in the procedure or WO, when performing calibrations if the as-found values are near the extremes of their acceptable range they should be adjusted. The following example shall be used to determine if adjustments will be made.

Example:

Input = 10 psig Output = 10 mA Tolerance = +.5 Accuracy Range 9.5 to 10.5 Required Calibration = 1 mA x 10% = .1 mA Values between 9.5 to 9.6 and 10.4 to 10.5 require recalibration.

4.4.9.3. Temporary electrical jumpers and lifter leads.

NOTE The instructions contained in AP 0315 are not provided to circumvent the requirements of AP 0140, Vermont Yankee Local Control Switching Rules, or AP 0020, Control of Temporary Modifications. Prior to utilizing AP 0315, it must be determined that these procedures do not apply.

To assure the proper administration and documentation of all temporary electrical jumpers and lifted leads AP 0315 must be used, unless the necessary controls are in the procedure being implemented.

4.4.10. Measuring and Test Equipment (M&TE)

I In accordance with the Entergy QA Program controls will be established to assure the I proper use and accuracy of M&TE. The I/C Department has established procedure DP 0301 for this purpose.

AP 0310 Rev. 20 Page 10 of 24

4.4.11, General Condition Inspections 4.4.11.1. During the performance of all surveillance procedures and maintenance activities, an inspection of the general condition of equipment being tested or worked on is to be accomplished. Also a determination of failure cause must be considered.

4.6. Administrative Controls 4.6.1. Field use of Controlled Documents The use of controlled documents such as P&ID's, CWD's, other Controlled Prints, VYEM's in the field is highly desirable and necessary when performing troubleshooting and repairs. The following process is designed to ensure that the necessary documents are available for use while ensuring that no work is performed with outdated or uncontrolled documents.

This instruction has been developed with the realization that there are differing situations in regard to the use of controlled documents and provides differing directions as to the control of this information.

4.6.1.1. Use of Documents in Clean Non-Contaminated Areas.

The original document may be used in this situation by signing out the document and inserting the card in the storage location.

The document must be returned to its storage location upon completion of work in its original condition.

4.6.1.2. Use of Documents in Contaminated Areas or where it couldbe destroyed or is to be marked-up.

Make a copy of the document and stamp it with the information below.

WORKING COPY OF: (P&ID,CWD,VYEM,OTHER)

TO BE USED FOR (WO # / OTHER)

VALID UNTIL (DATE):

The "VALID UNTIL" date shall not be more then 14 days from the date of the copy being produced.

Upon completion of work or expiration of valid date any mark-ups will be addressed and the copy destroyed.

4.6.2. Review and Control of Procedure Change Recommendations.

This section describes the internal review and change process. AP 0096 is the controlling document. The process described below is considered to be an enhancement to the parent document. This process is meant to provide good information to the procedure developers, effect a working communication link between commentor and resolver, and provide a method of resolving any difference.

AP 0310 Rev. 20 Page 20 of 24

4.6.2.1. Inter-Department Review and Comment Process The "Procedure Change Recommendation Form" (VYAPF 0096.05) will be available to all members of the department for communicating procedure enhancement opportunities.

This form with comments filled out by the initiator will be forwarded to the Support individual.

The Maint. Support Manager will assign a member of the Support Group the responsibility for reviewing the suggested change and resolving the comments.

The individual assigned to review and resolve the comments will meet with the initiator to further clarify the comments and discuss resolutions.

- Unresolved comments may be pursued by the initiator through the management organization.

Upon resolution of the comments, the individual performing this task will review the results with the Support individual. If procedure changes are required, a plan for making these changes within a proper time frame shall be established.

I

The disposition is approved by the Department Superintendent.

A copy of the completed VYAPF 0096.05 form will be sent to the originator.

For long term corrective action, a copy of this form will be placed in the shop procedure file for information.

AP 0310 Rev. 20 Page 21 of 24

APPENDIX C FAILURE CAUSE ANALYSIS A failure cause analysis should be considered as an adjunct to a corrective maintenance repair when the component that failed is safety or capacity related and any of the following apply:

The cause of the failure was not identified during the repair process.

The failure resulted in an LCO condition or degraded safety system performance.

The failure cannot be attributed to "end of life" with any degree of certainty.

Doubt exists in the mind of the Specialist or Maintenance Support individual that the replaced/repaired component won't fail in the same mode due to installation, design inadequacies.

Past history indicates similar failures of an unacceptable frequency.

The failure resulted in degraded plant system performance.

A cause analysis could be cost beneficial based upon gaining information that might decrease maintenance frequencies, or down time on the equipment.

APPENDIX D USE OF THREAD SEALANT FOR FLU[D/SYSTEMS MEMORANDUM TO: DISTRIBUTION . XVERNON DATE: 6/8/94 FROM: D.C. GIRROI>4 VERNON FILE: 3.1

SUBJECT:

THREAD SEALANT FOR FLUID/AIR SYSTEMS

References:

a) Memo, J.E. Gardner to T.A. Watson, dated 1/17/86, Use of teflon on primary system fittings b) Memo, H. Heilman to P.B. Corbett/G. Cappuccio, dated 4/27/94, Use of liquid thread sealants .......

c) General Electric RICSIL No. 67, dated 4/1/94, Use of thread sealants on scram solenoid pilot valves The above references provides guidance for sealing threads on swagelok fittings and small pipe fittings for both liquid and air applications.

The use of teflon tape and liquid sealants provide potential problems for safety related equipment and instrument components.

If teflon tape is not correctly applied to connections it can be dislodged and adversely affect valves, instruments and other vital equipment. This has occurred at least once at Vermont Yankee resulting in the leak rate testing failure of valves CRD-413A and 413B (see LER 92-10).

If liquid, thread sealant is not cautiously applied to connections intrusion into the process system is possible and may degrade certain components. Air systems with installed pilot valves using Buna-N and Dupont Viton elastomers are particularly susceptible to degradation when in contact with certain thread sealants. Neolube 100, Locktite PST 580, and Locktite 242 are specifically identified as inappropriate for use in air systems. Vermont Yankee has experienced specific problems with certain transmitter installations due to the use of liquid sealant.

Based upon the above discussion and consideration of the references, ME&C agrees that new guidance for sealing fluid/air systems is warranted.

Therefore:

1) Liquid thread sealant shall not be used in Service Air or Instrument Air system installations. When liquid thread sealant is used, great care shall be taken to insure that no liquid is applied to the first thread that enters the female thread. This practice will help to mitigate migration.

2) Teflon Tape thread sealant shall be used for all Service Air and Instrument Air Installations. Great / care shall be taken in using Appendix D AP Page0310 I ofRev.

2 20

APPENDIX D (Continued) teflon. A minimum of at least one full end thread on the NPT fitting shall be left uncovered to absolutely assure that no tape is left in contact with the process fluid.

3) Teflon tape thread sealant is also the preferred material for fluid connections which involve instruments. For other fluid system applications, the selection of thread sealing material will be decided on a case by case basis and will consider the fluid medium, pressure, temperature and any other environmental affects.

4) Training should be provided to all appropriate plant and contractor personnel in the proper application of teflon tape thread sealant and the prohibition of use of liquid thread sealant. The training shall also caution personnel to carefully clean both male and female fittings during all repairs or reinstallations.

5) Training should also be provided for all appropriate plant and contractor personnel in the proper installation procedure for swagelok tube fittings. Experience warrants' such training and this memo will serve to provide this recommendation.
