1.0 Introduction 1.1' Purpose  :

The Third-Interval Vermont Yankee Inservice Testing (IST) l Program establishes testing requirements to assess the l operational readiness of certain Safety Class 1, 2, and 3 pumps and valves which are required to:

a) Shut down the reactor to the cold shutdown condition, b) Maintain the reactor in the cold shutdown condition, or c) Mitigate the ccnsequences of design-basis accidents.

The Third-Interval IST Program is applicable for the interval-from September 1, 1993 through and including August 31, 2003

[ References (q) and (r)].

The Third-Interval IST Program is part of the Vermont Yankee Component Testing Program, i

1.2 Discussion The Third-Interval Vermont Yankee IST Program was developed in accordance with the requirements of the 1989 Edition of Section XI, Division 1, of the ASME Boiler and Pressure Vessel Code, " Rules for Inservice Inspection of Nuclear Power Plant Components," and 10 CFR 50.55a (Reference (b)]. The Third-  ;

Interval IST Program provides compliance with Vermont Yankee Technical Specifications 4.6.E.

I In accordance with Articles IWP-1000 and IWV-1000 and Table IWA-1600-1 of the 1989 Edition of Section XI, Division 1, of the ASME Boiler and Pressure Vessel Code and 10 CFR  !

50. 55a (b) (2) (viii) , the pump and valve testing requirements were based on the ASME/ ANSI OMa-1988 Addenda to ASME/ ANSI OM-1987, " Operation and Maintenance of Nuclear Power Plants".

The additional requirements described in 10 CFR

50. 55a (b) (2) (vil) and the recommendations described in Generic Letter 89-04 and its supplements were also included as applicable. Request for use of the ASME/ ANSI OMa-1988 Addenda to ASME/ ANSI OM-1987, with the additional requirements, was submitted by Vermont Yankee and approved by the USNRC

[ References (e) and (f)].

All references to the " Code" made within this IST Prograt Plan will 1987 refer to theotherwise unless ASME/ ANSI OMa-1988 Addenda to ASME/ ANSI OM-specified.

Revision 15 1-1

1 T' a y.

The IST Program Plan identifies the scope of components (pumps and valves) included in the Third-Interval IST Program, the testing requirements for those components, and justifications

, , or relief requests to support the scope and testing y requirements.

The IST Program Plan provides conformance with Article IWA- -

2420 of the 1989 Edition of Section XI, Division 1, of.the ASME Boiler and Pressure Vessel Code and 10 CFR 50.55a(a) (3) ,

(f)(5) and (f)(6).

The USNRC Safety Evaluations for the Third-Interval Vermont  !

Yankee IST Program are provided in References (s) and (u).

2.0 Program Plan Description The IST Program Plan is comprised of two independent subprogram plans - the Pump Inservice Testing Program Plan and the Valve Inservice Testing Program Plan.

Key features common to both Program Plans are: the Pump and Valve Listings that define the scope of the Third-Interval IST Program, Cold Shutdown and Refueling Outage Justifications, Relief Requests, and applicable Notes.

Administrative and implementing procedures, reference values, test results, and other records required to define and execute the Third-Interval IST Program are retained at Vermont Yankee.

2.1 Justifications In accordance with Paragraph 4.2.1.2 of Part 10 of the Code, certain valves are full stroke exercised during Cold Shutdown conditions when the valve cannot be exercised during Normal Operation. When the valve cannot be exercised during Cold Shutdown conditions, then the valve is full stroke exercised during Refueling Outages. The technical justification for exercising a valve during Cold Shutdowns or Refueling Outages, rather than during Normal Operations, is provided in a Cold Shutdown or Refueling Outage Justification.

Valves tested during Cold shutdowns or Refueling Outages shall be scheduled and tested in accordance with Paragraphs 4.2.1.2 (f), (g) and (h) of Part 10 of the Code.

Cold Shutdown and Refueling Outage Justifications are numbered.

in a "XXJ-VNN, Revision Z" format, where*

XXJ: CSJ for Cold Shutdown Justifications, )

ROJ for Refueling Outage Justifications. j J

V: for Valves. l l

NN: A unique sequential number, (e.g. CSJ-V03, Rev 0, I would be the third Cold Shutdown Justification for Valves).  !

Z: Revision Status.

l Revision 13 2-1

.2.2 Relief Requests

. Specific requests for relief are included in accordance with 10 CFR 50.55a(a) (3) , (f) (5) and (f)(6). Where conformance with the requirements of the Code have been determined to be impractical,' alternate testing is proposed that would provide an acceptable level of quality and safety. Where conformance with the requirements of the Code would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety, alternate testing is proposed that would provide useful information to assess the operational readiness of the component tested.

The Relief Requests define the component (s) and test (s) involved, the basis for relief, the proposed alternate  :'

testing, and the status of the USNRC evaluation to the Relief Request.

r If testing requirements are determined to be impractical during the course of the interval, additional or modified Relief Requests will be submitted in accordance with 10 CFR

50. 55a (f) (4 ) (iv) .  ;

Relief Requests are numbered in a "RR-YNN, Revision Z" format, where:

RR: for Relief Request.

Y: P for Pumps, V for Valves.

NN: A unique sequential number, (e.g. RR-V09, Rev 0, would be the ninth Relief Request for Valves).

2: Revision Status.

I Revision 13 2-2 s

t 2.3 Flow Diagrams Table 2-1 provides a. listing offthose Flow Diagrams which depict the components, subsystems, and systems contained within the Third-Interval IST Program. Drawing number G-191155 explains the symbols and designations provided on the Flow Diagrams.

The Safety Classifications depicted on the Flow Diagrams are subject to the limitations stated in procedure AP 0014,

" Safety Class Determination Instructions," and the Vermont Yankee Safety Classification Manual.

"For Information Only" copies of the Flow Diagrams shall be provided with each USNRC Submittal. The copies shall be current as of the date of the IST Program Plan submittal.

Controlled copies of the Flow Diagrams are maintained at Vermont Yankee to ensure that all system additions and modifications are addressed in the Third-Interval IST Program.

RELIEF REQUEST Numbert RR-P01, Revision j (Sheet 2 cf 4)

REQUEST FOR RELIEF: l 1

Relief is requested on the basis that compliance with the Code l requirements is impractical and that the proposed alternatives j would provide an acceptable level of quality and safety.  ;

i During normal operations, neither differential pressure nor flow rate can be fixed or directly measured. Pump vibration levels may also vary due to the inability to establish a repeatable reference condition.

The four Service Water pumps :.re vertical, two-stage, I centrifugal-type pumps which are submerged in and take suction l from the Connecticut River. They supply all the station Service  !

Water System requirements. The station Service Water System is a dual header system using two parallel headers each containing two pumps. The two parallel headers supply both the turbine and reactor auxiliary equipment, including the Residual Heat Removal I

Service Water System. A header interconnection is provided downstream of the pumps. Normally, the valves in the interconnecting line are open, permitting any of the pumps to supply the cooling water to both headers and to balance system operation. In addition, a cross-tie is provided to the non-nuclear safety station Fire Protection System. The 12-inch cross-tie valve is normally closed, with a 1-inch cross-tie and a restricting orifice providing pressurization of the Fire Protection System header.

The Service Water System contains both automatic temperature and flow control valves used to independently regulate the cooling provided to the various turbine and reactor auxiliary equipment.

Due to seasonal variations in Connecticut River water temperature and level and constantly changing heat loads, the system resistance and flow rate vary. The number of station Service Water pumps in operation is also varied dependent on system requirements. Due to these variations and the need to maintain prcper cooling, it is considered impracticable to establish repeatable reference values during quarterly inservice testing.

l The only sufficient straight sections of piping in each of the l two parallel headers exist between the i.. cake structure and the entrance to the reactor building. Use of this piping is i considered impracticable because: ,

a) These sections of the two parallel headers are buried P ii P ng. )

i b) As discussed above, each parallel header is common to two i pumps and is cross-connected to the other header. Thus, in i

. order to measure flow rate for one pump, the parallel pump in the same header would have to be secured and the valves in the header interconnecting line closed. This would i result in single pump operation for the portion of the ]'

station Service Water System supplied by the pump being tested.

c) All four station Service Water pumps are required to be operating during power operations and cold shutdowns during approximately 7 months of the year to meet cooling load  ;

requirements.  ;

Based on the above, significant redesign and modification of the station Service Water System would be required to obtain direct measurement of pump flow. Such redesign and modification would be costly and burdensome to Vermont Yankee.

RELIEF REQUEST Number: RR-P03, Revision 0 (Sheet 2 of 2)

REOUEST FOR RELIEF:

Relief is requested on the basis that the proposed alternatives i would provide an acceptable level of quality and safety.

Differential pressure across the HPCI pumps is determined by the 1 difference between pressure measurements taken at a point in the I inlet pipe and at a point in the discharge pipe as allowed by Paragraph 4.6.2.2 of Part 6 of the Code. The installed HPCI pump j inlet pressure indicators are designed to provide adequate inlet  ;

pressure indication during all expected operating and post  ;

accident conditions. The full scale range, 85 psig, is I sufficient for a post accident condition when the suppression l chamber is at the maximum pressure. This, however, exceeds the full-scale range limit of three times the suction pressure reference value as required by Paragraph 4.6.1.2(a) of Part 6 of the Code (Value = approximately 26 psig, Limit = 78 psig).

The suction pressure measurement is used to verify prescribed .

NPSH requirements and to determine pump differential pressure.

The installed gauges are calibrated to within +/- 1.58% accuracy (FS), thus the maximum variation in measured suction pressure due to inaccuracy would be +/- 1.34 psi. This is considered to be suitable for determining that adequate NPSH is available for HPCI pump operation.

Pump discharge pressure during testing is approximately 1170 psig, which results in a calculated differential pressure of approximately 1144 psig. The resulting inlet pressure inaccuracy of +/- 1.34 psi represents an error in differential pressure measurement of +/- 0.12% (1.34 psi /1144 psid = 0.0012). This is consistent with Table 1 of Part 6 of the Code, which requires that instrument accuracy for differential pressure be better than 2% of full-scale.

ALTERNATE METHOD:

Differential pressure will be measured using the existing station system installed inlet pressure indicators.

REQUEST FOR RELIEF:

4 Relief is requested on the basis that the proposed alternatives would provide an acceptable level of quality and safety.

A Past testing and analysis performed on the HPCI System by Vermont Yankee, the pump manufacturer, and by independent vibration consultants has revealed characteristic pump vibration levels which exceed the acceptance criteria stated in Table 3 of Part 6 of the Code. This testing and analysis meets the inten+ of Paragraph 4.3 and footnote 1 of Part 6 of the Code.

The root causes of the higher vibration levels have been determined to be:

a) An acoustical resonance in the piping connecting the low pressure (LP) and high pressure (HP) pumps, and b) The presence of a structural resonance in the horizontal direction on the HP pump.

These resonance conditions are design related and have existed since initial pump installation. They have been documented over a number of years of operating experience.

An additional past contributor to the higher vibration levels was the excitation resulting from the blade pass frequency from the previously installed four vane impeller in the low pressure (LP) pump. In an effort to reduce / eliminate this effect, the four vane impeller was replaced with a five vane impeller during the 1989 refueling outage. This replacement significantly reduced vibration levels in both the LP and HP pumps. However, due to the resonance effects referenced above, the HP pump vibration levels remain higher than the acceptance criteria stated in Table i 3 of Part 6 of the Code.

Although existing vibration levels in the HP pump are higher than standard acceptance criteria, they are acceptable and reflect the unique operating characteristics of the HPCI pump. It has been ,

concluded that there are no major vibrational concerns that would l prevent the HPCI pump from performing its intended function. l Revision 13 4-16

l RELIEF REQUEST Number: RR-PC4, Revision 0 (Sheet 3 of 3)

ALTEkNATE METHOD:

To allow for practicable vibration monitoring of the HPCI HP pump, alternate vibration acceptance criteria are required. Full spectrum vibrational monitoring will be performed during each quarterly test and the following criteria will be used for the HP pump:

Test Parameter Acceptable Rance Alert Ranae Reauired Action Rance VV s 2.5VI > 2.5VI to and > 6Vr but not including 6VI or > 0.70 in/sec

> 0.675 in/sec but not

> 0.70 in/sec In addition, the resonance peaks will be evaluated during each test and will have an Acceptable Range upper limit of 1.05 Vr and an Alert Range upper limit of 1.3 Vr.

The standard acceptance criteria of Table 3 of Part 6 will be applied to the LP pump.

REQUEST FOR RELIEF:

Relief is requested on the basis that the proposed alternatives would provide an acceptable level of quality and safety.

Differential pressure across the Core Spray pumps is determined by the difference between pressure measurements taken at a point in the inlet pipe and at a point in the discharge pipe as allowed by Paragraph 4.6.2.2 of Part 6 of the Code. The installed Core Spray pump inlet pressure indicators are designed to provide adequate inlet pressure indication during all expected operating and post accident conditions. The full scale range, 60 psig, is sufficient for a post accident condition when the suppression chamber is at the maximum pressure. This, however, exceeds the full-scale range limit of three times the suction pressure reference value as required by Paragraph 4.6.1.2(a) of Part 6 of the Code (Value = approximately 7.5 psig, Limit = 22 psig).

The suction pressure measurement is used to verify prescribed NPSH requirements and to determine pump differential pressure.

The installed gauges are calibrated to within +/- 2.0% accuracy (FS), thus the maximum variation in measured suction pressure due to inaccuracy would be +/- 1.2 psi. This is considered to be suitable for determining that adequate NPSH is available for Core Spray pump operation.

Pump discharge pressure during testing is approximately 240 psig, which results in a calculated differential pressure of approximately 232.5 psig. The resulting inlet pressure inaccuracy of +/- 1.2 psi represents an error in differential pressure measurement of +/- 0.5% (1.2 psi /232.5 psid = 0.0052).

This is consistent with Table 1 of Part 6 of the Code, which requires that instrument accuracy for differential pressure be better than 2% of full-scale.

ALTERNATE METHOD:

Differential pressure will be measured using the existing station system installed inlet pressure indicators.

Relief is requested on the basis that the proposed alternatives would provide an acceptable level of quality and safety.

Differential pressure across the RCIC pump is determined by the difference between pressure measurements taken at a point in the inlet pipe and at a point in the discharge pipe as allowed by Paragraph 4.6.2.2 of Part 6 of the Code. The installed RCIC pump inlet pressure indicators are designed to provide adequate inlet pressure indication during all expected operating and post accident conditions. The full scale range, 85 psig, is sufficient for a post accident condition when the suppression chamber is at the maximum pressure. This, however, exceeds the full-scale range limit of three times the suction pressure reference value as required by Paragraph 4.6.1.2(a) of Part 6 of the Code (Value = approximately 20 psig, Limit = 60 psig).

The suction pressure measurement is used to verify prescribed NPSH requirements and to determine pump differential pressure.

The installed gauges are calibrated to within +/- 1.58% accuracy (FS), thus the maximum variation in measured suction pressure due to inaccuracy would be +/- 1.34 psi. This is considered to be suitable for determining that adequate NPSH is available for RCIC pump operation.

Pump discharge pressure during testing is approximately 1130  !

RELIEF REQUEST Number: RR-P08, Revision 0 (Sheet 2 of 2)

REQUEST FOR RELIEF:

Relief is requested on the basis that the proposed alternatives would provide an acceptable level of quality and safety.

Differential pressure across the RBCCW pumps is determined by the difference between pressure measurements taken at a point in the inlet pipo and at a point in the discharge pipe as ellowed by Paragraph 4.6.2.2 of Part 6 of the Code. The installed RBCCW pump inlet pressure indicators, with a full scale range of 30 psig, are designed to provide adequate inlet pressure indication during all expected operating and post accident conditions.

-This, however, exceeds the full-scale range limit of three times the suction pressure reference value as required by Paragraph 4.6.1.2(a) of Part 6 of the Code (Value = approximately 6.5 psig, Limit = 19 psig).

The suction pressure measurement is used to verify prescribed NPSH requirements and to determine pump differential pressure.

The installed gauges are calibrated to within +/- 0.4% accuracy (FS), thus the maximum variation in measured suction pressure due to inaccuracy would be +/ .12 psi. This is considered to be suitable for determining that adequate NPSH is available for RBCCW pump operation.

Pump discharge pressure during testing is approximately 80 psig, which results in a calculated differential pressure of approximately 73.5 psig. The resulting inlet pressure inaccuracy i of +/- .12 psi represents an error in differential pressure measurement of +/- 0.16% (.12 psi /73.5 psid = 0.0016). This is consistent with Table 1 of Part 6 of the Code, which requires that instrument accuracy for differential pressure be better than 2% of full-scale.

ALTERNATE METHOD:

Differential pressure will be measured using the existing station system installed inlet pressure indicators.

Revision 13 4-26

l RELIEF REOUXET Number: RR-P09, Revision 0 (Sheet 2 of 4)

I BEQUEST FOR RELIEF:

Relief is requested on the basis that compliance with the Code requirements would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety and that the proposed alternatives would provide an acceptable level of quality and safety.

During quarterly inservice testing, pump flow rate cannot be directly measured.

The Emergency Diu'el Generator fuel oil supply system consists of two parallel tr_2ns, one for each diesel. Fuel oil is supplied directly to the diesel fuel block from the 800-gallon day tank.

Makeup to each diesel day tank is accomplished automatically from the 75,000-gallon storage tank by operation of the respective Diesel Fuel Oil Transfer pump. The diesel day tank is sized for three (3) hours of continuous full load operation, based on a diesel fuel oil consumption rate of approximately 3.4 gpm. The Diesel Fuel Oil Transfer pumps are positive displacement pumps with a design capacity of approximately 8.7 gpm.

It is considered impracticable to directly measure pump flow rate on a quarterly basis. There is no flow rate instrumentation installed in the Fuel Oil Transfer system. Sufficient straight sections of piping are required to properly measure flow rate, through the use of either permanently or temporarily installed instrumentation, such as non-intrusive flow measurement devices.

The only sufficient straight sections of piping exist in the buried sections of the supply headers. Installation of flow rate instrumentation or a pump test loop would require significant system redesign and modification, which would be costly and burdensome to Vermont Yankee.

Diesel Fuel Oil Transfer pump flow rate can be determined indirectly by measuring the level change in the diesel day tank versus the pump operating time required to make that change.

However, in order to allow for evaluation of the test results against the acceptance criteria of Table 3 of Part 6 of the Code, the test must be performed with the respective Emergency Diesel Generator secured. This eliminates the unknown variability of the diesel fuel oil consumption rate.

In addition, in order to provide measurement accuracy comparable with Table 1 of Part 6 of the Code, the automatic pump start feature on low diesel day tank level must be disabled and the diesel day tank volume reduced prior to the test through operation of the respective Emergency Diesel Generator.

Revision 13 4-27

RELIEF REQUEST Number RR-P09, Revision 0 (Sheet 3 of 4)

REQUEST FOR RELIEF fcon't):

Disabling the automatic start feature of the Diesel Fuel Oil Transfer pump on low diesel d. tank level lessens the ability of the Emergency Diesel Generator to operate automatically without operator assistance, reduces the availability of_an engineered safety system, and requires entry into a Vermont Yankee Technical Specifications Limiting Condition of Operation, with the required alternate testing requirements.

ALTERNATE METHOD:

During quarterly inservice testing of each Diesel Fuel Oil Transfer pump, it will be verified that the pump is capable of supplying fuel oil to the respective diesel day tank at a flow rate greater than that required by the operating Emergency Diesel Generator. This is verified by an increase in diesel day tank level during the diesel surveillance testing. In addition, full spectrum vibrational monitoring and measurement of pump discharge pressure will be performed with the results evaluated against the acceptance criteria of Table 3 of Part 6 of the Code.

Once each operating cycle the flow rate of each Diesel Fuel Oil Transfer pump will be determined indirectly by measuring the level change in the diesel day tank versus the pump operating time required to make that change. This will be performed with the respective Emergency Diesel Generator secured, the automatic pump start feature on low diesel day tank level disabled, and the diesel day tank volume reduced prior to the test through operation of the respective Emergency Diesel Generator. This testing will provide measurement accuracy comparable with Table 1 of Part 6 of the Code and the results will be evaluated against the acceptance criteria of Table 3 of Part 6 of the Code. As with the quarterly testing, full spectrum vibrational monitoring and measurement of pump discharge pressure will be performed with the results evaluated against the acceptance criteria of Table 3 of Part 6 of the Code.

Such testing is considered commensurate with the pump type and service and provides an acceptable level of quality and safety, based on the following:

Revision 13 4-28

4 RELIEF REQUEST Number: RR-P09, Revision 0 (Sheet 4 of 4) l l

ALTERNATE METHOD (con' tit a) A review of the pump design flow rate versus the diesel fuel oil consumption rate indicates an excess capacity of approximately 60 percent. As such, operational readiness of the pumps is still assured with up to 60 percent degradation, provided that pump bearing vibration is not excessive. Assurance of acceptable pump bearing vibration levels is provided through the full spectrum vibrational i monitoring. )

l b) A review of Vermont Yankee maintenance records and industry )

experience, as documented in NPRDS, indicates that the pumps are highly reliable and that the above testing methods are acceptable for assessing pump operational readiness and determining potential degradation.

At Vermont Yankee, four (4) failures have occurred in twenty l (20) years of plant operations. Of these failures, three (3) were related to electrical components and one (1) was related to high bearing vibrations. In addition, minor shaft seal leakage has been noted and corrected. s The industry experience is consistent with Vermont Yankee.

For similar pumps in similar applications, fifteen (15) failures have been reported via NPRDS. Of these failures, nine (9) were related to excessive seal leakage, four (4) ,

l were related to electrical components and two (2) were related to high bearing vibrations. l l

Each of the above failure modes is adequately monitored during the quarterly inservice testing through visual i inspection of the pump seals, proper starting and operation i of the pump upon low diesel day tank level, and full i spectrum vibrational monitoring.

5.3 Valvo Natos In addition to the acceptance criteria established in accordance with Part 10 of the Code, the below criteria will also be applied for the valves so noted in the Valve Listing (Table 5-1).

Note Criteria

1. Full stroke exercising and timing tests are accomplished quarterly when reactor power is decreased to less than ~5 percent. At least twice a week, the MSIVs are also exercised by partial closure and subsequent reopening.

2. Valves will also be disassembled and inspected at least once every 10 years. (LER 87-18 and NRC Inspection Report 50-271/87-21)

3. Testing of valve V3-138 is not required when the corresponding control rod has been declared inoperable and its directional control valves disarmed in accordance with the provisions of Technical Specifications 3.3.A.2.

4. During each refueling outage, explode one of the three charges manufactured in the same batch to verify proper function. Then install the untested charges in the explosive actuator.

5. Proper valve operation is shown by the decrease in pump discharge pressure upon opening of valves V10-16A/B and by

, proper automatic closure of V10-16A/B at approximately 2000 gpm.

6. Each refueling outage, each valve will be set pressure tested to determine the force required to open each valve from fully closed to fully open. This test satisfies the set pressure requirements of paragraph 3.3.2.3 (a) of Part 1 of the Code.

7. Only one valve in each line is required to be operable in accordance with Technical Specifications Table 4.7.2.b. l

8. Positive verification of full opening'of the valves is shown by J successful insertion of the Transversing In-Core Probe through i the valve. Positive verification of full closing of the valve ,

is shown during each Refueling Outage by successful leak testing (LJ). This testing . in compliance with Paragraph 4.1 of Part 10 of the Code which states "Where local observation is not l

possible, other indications shall be used for verification."

Local observation of valve position would require disassembly of the valve enclosures as the limit switches are contained within the enclosures.

Stroke testing!cf these valves quarterly during power operation is not recommended. As recommended by NUREG-0737 and the corresponding study by the BWF. Owners Group (BWR Owners Group Evaluation of NUREG-0737, Item II.K.3.16, " Reduction of Challenges and Failures of Relief Valves"), the exercising of these valves sl. mld be minimized to reduce the number of challenges to safety / relief ve'res.

Revision 16 5-89

1 REFUELING OUTAGE JUSTIFICATION j Number: ROJ-V02, Revision i (Sheet 2 of 2) l JUSTIFICATION (con't)- l The failure of any relief valve to close during stroking at power operation would cause an uncontrolled rapid depressurization of the  !

primary system (stuck oopen relief valve transient) along with an undesired positive reactivity excursion.

These valves can only be tested with primary system pressure greater than 100 psig, therefore, they cannot be exercised during cold shutdowns or during refueling outages. Exercising these valves at each start-up from cold shutdown (or quarterly) would produce additional stress cycles on the nuclear boiler system which could lead to a low cycle fatigue failure.

These valves will be exercised during plant startup after each refueling outage in accordance with Paragraph 4.2.1.2 (h) of Part 10 of the Code.

JUSTIFICATION: , ,

/

These valves cannot be tested during normal (power) operation because the feedwater system is required to maintain reactor vessel water level.

Interruption of feedwater to perform the exercise test of these valves would result in a reactor scram.

These valves can only be backflow tested via a leak type or non-intrusive test. Testing during Cold Shutdowns is impractical due to the significant system and test equipment configurations required. Additionally, valves V2-27B, V2-28B and V2-96A cannot be exercised during Cold Shutdowns since this would require removing the only mechanism of reactor vessel level control (via the Reactor Water Cleanup System).

These valves will be backflow exercised each Refueling Outage during leakage rate testing performed in accordance with Paragraphs 4.2.2.2 and 4.2.2.3 of Part 10 of the Code. Valves V2-27A, V2-28A, V2-28B and V2-96A will be exercised to the full open position by the proper operation of the feedwater system at plant startup. -

Valve V3-115 is the charging water to the CRD accumulator check valve.

This valve has a safety function in the closed position to prevent diversion of scram accumulator discharge into the charging header.

JUSTIFICATION:

Exercising valves CV-3-126, CV-3-127, V3-114 and V3-115 during power operation would require scramming the plant solely for testing purposes.

Since scram insertion times are representative of valve operability and stroke times, testing will be performed in accordance with Technical Specifications 4.3.C.1 and 2. These sections require that all control rods be subjected to scram-time measurements on a refueling outage basis and that 50% of the control rods be measured for scram times every 16 to 32 weeks. An evaluation is required that provides reasonable assurance that proper control rod drive performance is being maintained. These tests will adequately verify valve operability and stroke times.

Valves SE-3-120 through 123 are verified operable at least once a week in accordance with Technical Specifications 4.3. A.2 for each partially or fully withdrawn operable control rod. For a control rod that is fully inserted, the safety function of these valves is fulfilled. Stroke testing these valves while the control rod is fully inserted will not result in an increase in safety or quality. All control rods drives are verified operable in accordance with Technical Specifications 4.3.B.1 each Refueling Outage, thus stroke testing of these valves for control rods that remained fully inserted throughout the operating cycle will occur each Refueling Outage.

These valves will be exercised as a minimum each Refueling Outage in accordance with Paragraphs 4.2.1.2 (h) and 4.3. 2. 2 (h) of Part 10 of the Code.

CODE REQUIREMENT (con' t) : Part 10 Para. 4.2.1.3 " Valve Obturator Movement" "The-necessary valve obturator movement shall be determined j

' by exercising the valve while observing an appropriate indicator, such as indicating lights which signal the

i REQUEST FOR RELIEF:  ;

i

. Relief is requested on the basis that compliance with the Code requirements is impractical and that the proposed alternatives would  :

provide an acceptable level of quality and safety.

These valves do not have remote position indication. Measuring the stroke time of these valves by observing stem travel would require disassembly of the operator. .

Testing of the inlet valves individually would require the lifting of the -;

power leads to the other valve. Since the stroke timing of these valves  !

is performed by the indirect indication of the respective EDG start time, to lift leads each quarter and perform the necessary EDG fast starts to verify each valve's stroke time would be an undue hardship. Because  !

excessive EDG> fast starts are a known contributor to decreased EDG reliability and owing to the criticality of the EDGs as part of the ECCS system, the overall impact of testing these valves in accordance with Code i requirements would be an overall decrease in plant safety. Furthermore, since~the air start system is not totally, redundant (e.g. they share r common piping, components and initiating logic), testing of these valves  !

individually on a quarterly basis would not increase the quality and i safety of the system.

ALTERNATE METHOD:

During EDG slow start testing performed each month, indirect indication  !

that at least one of the two parallel air start inlet valves cpens, and  :

the vent valve closes, will be performed by ensuring the EDG starts.

ALTERNATE METHOD (con' t) :

During EDG fast start testing performed every six months, indirect measurement that at least one of the two parallel air start inlet valves opens promptly, and the vent valve closes promptly, will be performed by ensuring the EDG starts within the Technical Specification limit of 13 seconds. Measuring the EDG start time gives indication of possible valve degradation (as a pair) since any signiff. cant changes in valve stroke time will be identified by longer than normal EDG start times.

In addition, to further assess the operational readiness of each air start inlet valve, an independent operability test is performed once per operating cycle. This test will be accomplished by alternately lifting the power leads to one of the two air start valves, and then measuring the EDG fast start time with the remaining valve in operation.

REQUEST FOR RELIEF: ,

Relief is requested on the basis that compliance with the Code requirements is impractical and that the proposed alternatives would provide an acceptable level of quality and safety.

The motive for.' for the HPCI turbine Stop and Control valves is supplied from the Turbine force feed lubrication system. A review of historical data indicates that variations in valve stroke times exist between tests run with a primed versus an unprimed hydraulic system. Similar effects  :

have been seen at other plants, as described in General Electric SIL No.  ;

336, Revision 1.  !

d Revision 16 5-120 t

RELIEF REQUEST Number: RR-V06, Revision 0 (Sheet 2 of 2)

REOUEST FOR RELIEF (con' t) :

To minimize the amount of 'ariability induced by the degree of hydraulic system priming, the Turbine Stop and Control valves are timed from onset of valve movement as shown by receipt of intermediate position indication to full open indication during valve surveillance testing. This timing method minimizes the affects that the tim' required for hydraulic priming would otherwise have on the valve's stroke time. Although the hydraulic priming affect is reduced, the historical data still indicates average variations in valve stroke times as follows:

HPCI-CONTROL Open 29%

Close 43%

HPCI-STOP Open 13%

. Close N/A - Rapid Acting The average variations for the HPCI-Control valve are greater than the Code acceptance criteria of 25% of the reference value.

ALTERNATE METHOD:

The acceptance criteria for the HPCI turbine Control valves will be expanded to 1 35% in the open direction and i 50% in the closed direction.

In addition, a time-to-rated flow test for the HPCI system will be performed once each operating cycle to demonstrate satisfactory integrated response of the control, hydraulic and mechanical components.

RELIEF REQUEST Number: RR-V08, Revision 0 (Sheet 2 of 2)

REQUEST FOR RELIEF:

Relief is requested on the basis that the prenosed alternatives would provide an acceptable level of quality and e% ety.

Vermont Yankee Technical Specifications 4.4 t requires testing of valves SR-11-39A & B at least once every operating fcle. This testing frequency represents a six-fold increase over the tete ing frequency required by Part 1 of the Code and, as such, yields more accurate valve degradation trending data. The testing is currently perforued at the Vermont Yankee plant site.

The acceptable range of relief valve actuation given in Technical Specifications 4.4.A is 1400 psig to 1490 psig. The 1400 psig value ensur s that a sufficient injection pressure can be established prior to lifting of the relief valve. The 1490 psig value ensures relief valve actuation prior to reaching the system design pressure of 1500 psig. 1490 psig translates into a maximum relief valve setpoint of 99% of system design pressure as opposed to 110% allowable by the piping code. Applying the Part 1 tolerance of 3% to the current setpoint would unnecessarily reduce the acceptable range to 1400 psig to 1442 psig (1442 psig = 96% of system design pressure).

The increased testing frequency and present setpoint requirements provide adequate assurance of the operational readiness of valves SR-11-39A & B and, as such, no significant increase in the level of safety or quality can be expected if the subject Code requirements are imposed.

ALTERNATE METHOD:

In accordance with Vermont Yankee Technical Specifications 4.4.A, valves SR-11-39A & B shall be tested at least once every operating cycle. The setting of the valves shall be between 1400 and 1490 psig.
