I Millstone Unit 3 MOV Program Octobcr 6,1995 CLOSURE OF MP3 GL 89-10 PROGRAM 4

Executive Summary This document describes the bases for Millstone Unit 3's closure of the design-basis veri 0 cation phase of NRC Generic Letter 89-10," Safety-Related Motor-Operated Valve Testing and j

Surveillance." This report was prepared to serve as a living document which controls the GL 89-10 1

design requirements, and provides in one place sufficient information to verify GL 89-10 closure.

This has been accomplished by deGning the Northeast Utilities Motor-Operated Valve Program as implemented at the Millstone Unit 3 Plant. Included in the report are actions taken to date, as well as descriptions of the longer-term program being implemented for on-going testing and surveillance of safety-related motor-operated valves (MOV's). This program verined and ensures MOV operability under design-basis differential pressure and How conditions.

in November of 1985, the NRC issued Bulletin 85-03 recommending licensees develop and 4

implement a program to ensure the reliability of MOV's in several safety-related systems. In June of 1989, the NRC issued Generic Letter (GL) 89-10 recommending licensees develop a comprehensive program to ensure MOV's in safety-related systems will operate under design-bases conditions and mispositioned conditions.

Northeast Utilities (NU) committed to develop a detailed program for addressing GL 89-10 at Connecticut Yankee, Millstone Unit No.1, Millstone Unit No. 2, and Millstone Unit No. 3 nuclear power plants. All safety-related MOV's and position-changeable MOV's in safety-related piping systems are included in this program. This program includes demonstrating the operability of safety-related MOV's by analysis and in-situ Dow tests at or near design-basis conditions, where practicable. The objectives of our program are to:

increase MOV operability assurance through a long-term preventive maintenance e

and trending program.

Identify problem valves early (i.e., experience no failures during plant operation).

e Minimize extended outages due to MOV testing related activities.

The NU MOV Program Manual specifies criteria and requirements for NU's implementation of GL 89-10. The MOV Program Manual applies to the Connecticut Yankee, Millstone Unit No.1, Millstone Unit No. 2, and Millstone Unit No. 3 nuclear power plants. It is the controlling document for Northeast Utilities Service Company (NUSCO), Northeast Nuclear Energy Company (NNECO),

Connecticut Yankee Atomic Power Company (CYAPCO), and contractors performing MOV Program activities at Northeast Utilities. The MOV Program Manual consists of the following sections:

Introduction Objectives, purpose, scope and applicability.

Responsibilities Responsibilities of key individuals / groups.

Integration Interfaces with other groups and individuals.

Technical Requirements Technical Requirements of the MOV Program.

Millstone Unit 3 MOV Program October 6,1995

1. Purpose The purpose of this document is to summarize, in one place, closure of the design-basis phase of GL 89-10, and future changes which impact design basis considerations. It also provides the baies for MOV settings and configuration. Finally, this report serves as a living document which will be periodically revised as anc element in configuration control. This closure report will be maintained as a controlled document within the MOV Program Manual and updated as necessary.

It is currently envisioned that this document will be reviewed after each refueling outage if changes are made which impact MOV functionality or GL 89-10 MOV design compliance. This document will not control control-switch setpoints, future test data, or calculation numbers. These and other parameters are controlled by NU procedures. Tables 6,7,10, and 17 will not be maintained as living. An example of an item which will result in a revision is a design change requiring revalidating design-basis capability.

2. Introduction On June 28,1989, the NRC stafTissued Generic Letter 89-10," Safety-Related Motor-Operated Vaive Testing and Surveillance,"' which provided recommendations to the licensees for the development of adequate programs to ensure operability of safety-related MOV's during design-basis conditions. The generic letter recommended that each licensee with an operating license complete all design-basis reviews, analyses, verifications, tests and inspections that have been instituted within five years or three refueling outages, whichever is later, of the date of the generic letter (June 28,1989).

The staff held public workshops to discuss the generic letter and to answer questions regarding its 2

implementation. On June 13,1990, the staffissued Supplement 1 to Generic Letter 89-10 to 3

provide the results of the public workshops. In Supplement 2 to Generic Letter 89-10, issued on August 3,1990, the staff stated that inspections of programs developed in response to the generic letter would not begin until January 1,1991.

In response to concerns raised by the results of NRC-sponsored MOV tests, the staffissued 4

Supplement 3 to Generic Letter 89-10 on October 25,1990. This supplement requested that Boiling Water Reactor licensees evaluate the capability of MOV's used for containment isolation in the l

steam lines to the high pressure coolant injection system and reactor core isolation cooling system; in the supply line to the reactor water cleanup system; and in the lines to the isolation condenser, as applicable.

5 On February 12,1992, the staffissued Supplement 4 to Generic Letter 89 10 excluding considerations for inadvertent operation of MOV's from the scope of Generic Letter 89-10 for 6

Boiling Water Reactors. On June 28,1993, the staffissued Supplement 5 to Generic Letter 89-10 which requested that licensees review their MOV programs and to identify measures taken or planned to account for uncertainties in properly setting valve operating thrust due to increased inaccuracy of MOV diagnostic equipment.

7 Supplement 6 to Generic Letter 89-10, issued March 8,1994, further clarified NRC positions on the schedule for completing MOV testing to verify design-basis capability and grouping of MOV's to i

establish valve setup conditions. This supplement also provided staff responses to other general j

public questions.

3. Proactive Features of the MOV Program Used a 0.6 valve factor for non-testable gate valves based upon review of Electric o

Power Research Institute (EPRI) Performance Prediction Methodology (PPM) results.

Use of the Kalsi Engineering Inc., KEl Gate Program for non-testable valves to validate our 0.6 valve factor assumption. In cases where the KEl Gate yields a value

> than 0.6, the " bounding" KEl Gate value is used to deHne the thrust window. KEI Gate was performed for NNECO due to delayed issuance of the EPRI PPM.

Developed a comprehensive structural analysis procedure and replaced diverse vendor seismic weak link calculations with consistent calculations for all GL 89-10 valves.

Backfit ASME Code, stress-based requirements to Haddam Neck, Millstone Unit 1, and Millstone Unit 2.

Determined acceptable pressure boundary integrity at actuator stall in cases where actuators have been modified and stall thrust increased significantly.

Employ consistently determined results from three other nuclear units, thereby adding further validation to MOV program assumptions.

Performed laboratory design-basis dynamic tests for selected replacement valves.

This work was performed for Northeast Utilities by the broadly recognized Alden Research Laboratory in Massachusetts.

Provided special treatment of Westinghouse gate valves in high differential pressure

=

applications. Not yet published EPRI research was used to define a more conservative set of acceptance criteria for two Westinghouse MOV's in high pressure applications.

Developed a more accurate model to evaluate stroke time for DC-powered actuators.

A specific linkage was drawn between higher assumed valve factors and stroke time, Compiled digital photographs of MOV's for easy storage, retrieval and review.

4. Program Scope The objective of the Millstone Unit 3 MOV Program is to ensure MOV operability under design-basis differential pressure and flow conditions. This entails several program elements to:

(1) determine the design-basis conditions, (2) determine the physical limitations of the valve and actuator, (3) perform the requisite testing and evaluate the data to determine the appropriate limit and / or torque switch settings, and (4) ensure that operability is maintained throughout the life of the plant through on-going maintenance activities and design control measures.

Setup and testing of the valves is accomplished using the Liberty Technologies Valve Operation Test and Evaluation System (VOTES) and other state-of-the-art measurement techniques (e.g., QSS -

Quick Stem Sensor and MPM - Motor Power Monitor).

Millstons Unit 3 MOV Program October 6,1995 Millstone Unit 3's administrative program is defined by Nuclear Group Procedure (NGp) 2.32,

" Engineering Programs" with specific detailed procedural requirements contained in the Motor-Operated Valve Program Manual. Other ancillary procedures govern more specific aspects of the program such as use and calibration of test equipment and adjustment of switches, Finally, procedural interfaces exist with other programs governing routine maintenance, plant design changes and modifications, corrective action programs, and identification of non-conforming materials.

The Millstone Unit 3 MOV Program is based upon satisfying two key technical requirements. These are (1) the physical limitations of the valve and actuator based on allowable limits of subcomponents (e.g., torque limits on the actuator, thrust limits, valve component structural limits, etc.) and (2) the required differential pressure and flow environment in which the valve must function. Other effects such as operation at reduced voltage and elevated temperatures, use of proper stem factors, pressure locking and thermal binding have also been considered.

There are one hundred and forty three (143) motor-operated valves included in the Millstone Unit 3 MOV Program scope. A summary of valve types, disk type and valve manufacturer is defined in Table 1.

5. Status of GL 89-10 Program MOV's As of June 1995, all initial design reviews, valve set-up and static tests of the 143 valves in the Millstone Unit 3 GL 89-10 MOV Program were completed by the end of refueling outage RFO 5, the third refueling outage after the release of GL 89-10. Of the 143 MOV's in the program,102 were statically tested during RFO 5. Of the 94 testable MOV's in the program; 35 MOV's were dynamically tested during RFO 5,22 MOV's were tested the previous outage, for 6 MOV's the static test constituted the design-basis verification because the static breakaway torque requirements dominate the torque requirements,14 MOV's were grouped with other tested MOV's, and 17 MOV's were not dynamically tested due to high calculated margin / capability.

Information about each MOV in the Millstone Unit 3 MOV Program is contained in numerous tables within this report. Table 2 contains the valve tag number and system label name along with the functional description of each valve.

Provided in Table 3 is the quantitative-based Probabilistic Risk Assessment (PRA) priority for each 8

valve. All MOV's were reclassified in 1995 using component risk achievement worth (RAW) importance parameters. The new prioritization scheme is based upon superior insights and state of the art knowledge in comparison to the previous MOV prioritization schemes.

l Millstone Unit 3 MOV Program October 6,1995 10.5 Valve Factor NU's technical position on gate valve, valve factors (Vf's) reflects the "best available knowledge."

- Actions taken by NU in response to the November 30,1993, NRC Information Notice," addressing valve factor data, are contained in a memo" in the MOV Program Manual. The MOV Program Manual provides the criteria used to choose Vf for gate valves in the GL 89-10 program for operability, design set-up and for GL 89-10 closure.

"Best available data" was derived from quality assurance (QA) reviewed EPRI Performance Prediction Program (PPP) valve test results,' other industry testing, and guidance contained in Reference 16. EPRI results confirm 1.1 is an appropriate value for globe valve design set-up.

However, evaluation of this information prompted the adoption of increased valve factors for gate valves in many cases. Prior to this change NU had used vendor supplied valve factors or had assumed a 0.3 Vf for gate valves. A comparison ofNU GL 89-10 MOV's was made to the valves tested in the EPRI program. The results of this comparison" revealed no matches between EPRI valves and NU non-dynamically testable MOV's.

Table 14 summarizes the criteria used by NU for different categories of pate valve Vf's under varying plant conditions and for different phases of the MOV Program.' These values are used to achieve flow isolation in the close direction and are assumed to be applicable in the open direction.

The " Design Set up" values were used in conjunction with PI-9 during the preparation of target thrust calculations.

)

(2) Definitive determination of Vf and operability will be provided by dynamic testing properly adjusted to Design Basis conditions.

(3) A Vflower than 0.3 may be used ifjustified by test results.

(4) EPRI data indicates a Vf of 0.4 is a bounding value for stellite surfaces under high contact stress, flat-on-flat disc-to-seat contact, at temperatures above 350 F. An allowance of 0.2 is provided to allow for " poor geometry" and the differences between mu and Vf.

38 f

Millstone Unit 3 MOV Program October 6,1995 (5) With the torque switch bypassed until Dow isolation, the thrust at this Vf -

constitutes the design-basis thrust due to dynamic conditions to be used for structural evaluation.

(6) Use of a Vf 2 0.4 is an interim operability screening value for use at each unit until their first refueling after December 4,1993. This is a more realistic number than the 0.3 Vf previously used in NU's MOV Program Manual. A 0.4 Vf bounds about 50% of EPRI blowdown tests; is the minimum value stated in Reference"'; and is a " good geometry" bounding value for high contact stress, flat-on-flat disc-to-seat contact, at temperatures above 350 F.

It is not considered a conservative value.

(7) "Other" includes technicallyjustifiable approaches, e.g. special tests, analysis, etc.

(8) A 0.4 Vf bounds the limited EPRI PPP test data for parallel-disc Anchor-Darling gate valves at temperatures > 350 F. This is also consistent with the results of blowdown testing performed by Anchor-Darling. EPRI testing also indicates 0.4 is a bounding value for high contact stress, flat-on-flat disc-to-seat contact, at temperatures above 350 F.

(9) A 0.9 Vf bounds virtually all empirical data for gate valves.

Valve factors and measured rate ofloading values for each MOV are provided in Table 15. The shaded areas represent MOV's set up on limit switch or torque switch bypacs control.

Millstone Unit 3 MOV Program October 6,1995 10.6 Stem Factor / Stem Friction Coefficient Millstone Unit 3 calculations use a stem factor based on a friction coefficient of = 0.18 or greater for all valves unlessjustification is provided. This assumption is based on information and -
experience from the following sources:
Industry experience Testing performed by Northeast Utilities e
Limitorque sizing procedures e
Millstone Unit 3 NCR 393-438,"MOV Stem / Stem Nut Coefficient of Friction," dated e
September 25,1993.
NMAC Application Guide for Motor Operated Valves in Nuclear Power Plants, NP-6660-D EPRI Stem / Stem-Nut Lubrication Test Report, TR-102135 e
1 The actuator of an MOV produces torque. For rising stem valves, the torque produced is converted to thrust at the stem and stem nut interface, or yoke-nut for rising rotating MOV's. The stem and stem-nut / yoke nut is a power screw which in most cases uses ACME threads. The emeiency of conversion of torque to thrust by the stem and stem-nut / yoke-nut is called the " Stem Factor." The stem factor is determined by stem geometry and the coefficient of friction between the stem and the stem-nut / yoke-nut. Since the geometry of a given stem is fixed, any change in coefficient of friction will change the stem factor.
Industry testing has shown that the coefficient of friction can vary over a range of about 0.08 to 0.20.
j This range of friction coefficient can change the output thrust for a given torque input by 250%,
thereby potentially effecting its ability to perform its intended function. Determining and maintaining a stem to stem-nut coefficient of friction is dependent upon mechanical condition, 4
lubricant used, lubricant condition, and preventive maintenance practices.
Measurement of torque and thrust under static conditions may not provide an accurate representation of coefficient of friction for the design-basis condition. Under static running load conditions, the load on the stem to stem-nut is not high enough to maintain even contact loads between the stem and stem-nut, causing the two to " float". This produces large swings in the measured coefficient of friction. Measurements taken at static torque switch trip can also be misleading, since at this point in the valve stroke there is little or no actual rotational movement. Under this condition, the measured coefficient of friction although consistent, will usually be lower than the actual value under design-basis conditions.
i Northeast Utilities has validated the assumed p = 0.15 by monitoring torque and thrust durmg selective dynamic tests for Haddam Neck, Millstone Unit 1, and Millstone Unit 2 for valves with similar lubrication practices. Millstone Unit 3 testing indicated that = 0.18 would bound data obtained. The disposition of NCR 393-438 identified past lubrication practices as the root cause for higher coefficient of friction. Table 16 provides the results of all applicable valid stem coefficient data measured in NU's MOV Program to date. As can be seen, p = 0.15 bounds 100 percent of the data for Haddam Neck, Millstone Unit 1, and Millstone Unit 2. For Millstone Unit 3,
= 0.18 bounds 100 percent of the test data.

Where possible, NU's MOV's were tested using the VOTES Torque Cartridge / Quick Stem Sensor (VTC / QSS) to validate our selection of friction coefGeient. Currently we have obtained 29 data points for coefficient of friction for the four Connecticut units. These data points were obtained under dynamic (i.e., flow and differential pressure) conditions, to best represent design-basis conditions. As noted, all data points are below 0.15 for Haddam Neck, Millstone Unit 1, and Millstone Unit 2, and below 0.18 for Millstone Unit 3; therefore validating our assumption. To add further rigor to NU's MOV Program, we are assessing the use of statistical analysis of our final data set (post Millstone Unit I completion) as a validation methodology. This will require additional data to permit meaningful statistical analysis.
10.7 Margin l
The definition of margin varies from one licensee to another. Making simple comparisons of the numerical value is an unreliable indication. For example, NU's quoted margin is approximately 2D l
percent greater than a licensee who uses 0.5 for a non-testable gate valve factor, if all other parameters are the same. The definition of margin is provided below:

1075 FUS 10.8 Stem Lubrication and Springpack Relaxation The MOV Program assumes little or no degradation of stem lubricant will occur between maintenance intervals. This is based on a preventive maintenance program, and using the " reservoir method" of stem lubrication, which limits degradation of stem lubricant. To validate this assumption,"as-found" dynamic tests may need to be performed unless another means of monitoring stem lubrication effectiveness statically can be developed. Currently, use of motor power to provide this capability without further dynamic testing is being evaluated. The small number of as-found tests conducted to date indicate that there is no lubrication degradation using the reservoir method, therefore validating our assumption that additional margin is not required. However, for those MOV's with small overall margin, we will continue to closely monitor for changes.

Millstone Unit 3 MOV Program October 6,1995
-1 10.9 Selection of MOV Switch Settings item b, of GL 89-10 requires that methods exist for selecting and setting MOV switches (i.e., switch settings) to ensure high reliability of safety-related MOV's. MOV sizing calculations and methods for determining switch setting are described in PI-9," Determination of Stem Thrust Requirements,"
i memorandum MOV-RTH 93-034,"NU MOV Program: Acceptance Criteria for Gate Valve, Valve Factors (Vf),"" and target thrust calculations. PI 9 establishes the methodology for determining the target torque and thrust values for globe, gate, and %-turn valves, and the corresponding control switch settings. In addition,it provides instructions for determining a MOV's capability. The appropriate limit and torque switch settings are determined following the valve capability analysis.
MOV limiter plate sizing to prevent exceeding torque based limits is also included in PI-9. It is j
conservative to use the motor pull-out efficiency to calculate valve thrust requirements for the open f
and closed cases, however it is also permissible to use the motor running efficiencies for closed cases, for AC actuators.
j Design set-up calculations for determining thrust requirements and actuator capability assume the 1
following: a valve factor of 0.4 for rising stem gate valves that will be dynamically tested; 0.6 for non-testable wedge gate valves; and 0.4 for non-testable parallel disc gate valves. For the non-testable valves or where representative dynamic conditions cannot be reasonably created, NU plans to use "best available data" in determining valve factors (e.g., the EPRI Performance Prediction Program, Kalsi Engineering evaluation, or from grouping of data from other dynamic tests). We 1
reviewed preliminary information provided by EPRI's Performance Prediction Program and used i
this information as a basis for raising our valve factor assumptions from the previous standard assumption of 0.3 for wedge gate valves. For Millstone Unit 3 a stem friction coefficient of 0.18 is used for determination of actuator output thrust capability. Thrust requirements for setting of actuator torque switches are adjusted to account for diagnostic equipment inaccuracy and torque switch repeatability.
The design-basis thrust calculations specify a 1.1 margin for non-testable gate / globe valves to account for load-sensitive behavior (also known as " rate of loading"), unless the valve is on torque switch bypass (see Section 10.10). Load sensitive behavior data obtained from dynamic tests (i.e.,
testable gate / globe valves) is incorporated into target thrust calculations. Load sensitive behavior can reduce the thrust delivered by the motor operator under high differential pressure and flow conditions from the amount delivered under static conditions. The MOV Program allowance of 1.1 is based upon NU specific measurements statistically analyzed as a truncated normal distribution to exclude negative values (see Section 11.3). We will continue to monitor industry development of increased understanding of this phenomenon and make changes to our analysis results" to account 4
for load sensitive behavior.
Four-rotor limit switches are installed on all actuators in the Millstone Unit 3 GL 89-10 program.
Actual limit switch settings are in the MOV schematic diagram or ESK drawings. The following limit switch settings apply to all MOV's, unlessjustified for a different setup, and are documented in accordance with PI 8," Control of MOV Settings":
j.
Open Limit - shall be set to 5% (nominally) from the full open valve position. The exact set point shall be determined on a case by case basis in order to ensure the valve does not torque into the backseat, coast into the backseat or adversely effect the' stroke time of the MOV. The open limit shall be adjusted for the additional coast due to the piston efTect ofline pressure. The setting shall also be selected such that the valve disc does not excessively protrude into the flow stream.
45 2
) '.
t v
Millstone Unit 3 MOV Program October 6,1995 Close Limit - shall be set 0 to 10% from the valve full closed position (hard seat contact / flow isolation) on limit closed valves. This setting is only applicable if the original plant design basis utilizes the close limit switch in its control circuit and the actuator speed requires closing on limit.
Open-to-Close Bypass - shall be set greater than 5% from the full open valve position on MOV's designed to backseat only. Otherwise, there are no requirements.
The "97% nominal close torque switch bypass"(CTSB) may be used. In this application the close torque switch is bypassed until flow cut offis ensured. Once the port is covered the torque switch comes back in the circuit and controls closure.
A limit switch repeatability of I % shall be applied to CTSB setpoint to ensure the port is covered and the motor is cut off before hard seat contact. Use of a limit switch repeatability less than 1% may bejustified by performing limit switch repeatability tests or via correlation to existing NU limit switch repeatability data.
All limit switch repeatability data must be statistically analyzed to ensure proper sample size and to confirm the actual limit switch repeatability is within a 95%
20 confidence range,
y Close-to-Open Bypass - shall be set greater than 45% from the full closed valve position. This setting is critical to ensure operability of the valve. (Note: Some valves have interlocks which required setting at 20% from full closed.)
Open position indicator (green light off)- shall be set to trip within *0% to -2%
(of full stroke) of open control switch trip, for MOV's which open on limit. For MOV's which intentionally backseat, the switch shall be set in accordance with Unit Engineering requirements.
Close position indicator (red light off)- when MOV is torque closed then light shall be set no greater than 3% (of full stroke) before hard seat contact and no greater than 15% (of the distance between hard seat contact and CST) after hard seat contact. Iflimit switch controlled, the switch is set in accordance with an approved set-up procedure.
Intermediate Limits - Limits providing interlocks, status inputs, and special signals must be set so the limit switch at least changes state prior to the valve control switch.
For gate valves, limit control in the closing direction may be used in lieu of torque switch control, as appropriate. The limit switches associated with Limitorque actuators are used for various functions including interlocks, position indication and controlling valve position. The limit switches are gear-driven directly off the drive sleeve for models SMB-000 and SMB-00 or the worm shaft for mod-is SMB-0 through SMB 5. With this arrangement, it is possible to adjust a limit switch to control valve position within a few hundredths of an inch. For the nonnal uses the limit switch is put to, this fine control is not necessary, and therefore has not been evaluated.
Control of motor-operated gate and globe valves in the closing direction is normally performed by the torque switch. In certain cases, control by use of the limit switch is desirable. These cases include high inertia, bypassing the close torque switch until flow isolation is achieved, and butterfly /
plug (quarter-turn) valves. In all cases the valve is being controlled by stem position rather than 46
Millstone Unit 3 MOV Program October 6,1995 output torque. The allowable band of stem position in these situations is very small, sometimes as little a one quarter inch, so the ability to set the limit switch to control in these regions is critical."
In addition to the ability to set the limit switch, some determination of the ability of the switch to trip at the same point each time must be made. The repeatability of the limit switches for Limitorque actuators is commonly reported at 2 to 3%. There has been no industry documentation of any testing or evaluation oflimit switch repeatability. The purpose for which we use limit switch control of valve closure on a gate valve requires better repeatability than 2 to 3%. NU has determined limit switch repeatability for particular applications based upon statistical analysis of multiple valve strokes 2 (see Section 12 2.3).
At Millstone Unit 3, only the 46 butterfly / plug valves are set-up on limit switch control.
10.10 Torque Switch Bypass Methodology NU has implemented a methodology of bypassing the torque switch until flow cutoff. This control configuration is similar to limit-closed configuration because the full capability of the motor actuator is available to close the valve.1lowever, NU's torque switch bypass configuration differs because the limit switch removes the torque switch bypass until flow cutoff and not the motor power. This allows the motor to ensure the disk covers the flow path then fully seat the disk based on torque.
switch trip. The torque switch setting is adjusted as high as possible to provide the greatest assurance of proper valve seating under a static condition.
Using this control configuration, a possibility exists during a close stroke under dynamic conditions for the motor torque to exceed the torque switch trip setpoint, which is bypassed. As a result, when the torque switch bypass is removed (after flow cutoff), motor power will be cut off after flow is stopped and, possibly, prior to hard seat contact. NU uses information contained in EPRI's NUMAC, " Application Guide for Motor-Operated Valves in ' Nuclear Power Plants," as guidance on the sealing contact force required to obtain a leak tight seal.
Terque switches are generally bypassed in the opening direction for approximately the first 45 - 65%
of the stroke. The open limit switch is used to control termination of the open stroke for rising stem and rising / rotating stem valves to prevent backseating of the valve. The torque switch is bypassed in the closing direction except for the last 5-20% of the stroke. For butterfly valves, open and close torque switches are bypassed 100% of open and close travel.
11. Design-Basis Capability 11.1 in-situ Design Basis Verification Testing item c. of GL 89-10 requires that each MOV be tested in-situ at design-basis conditions, if practicable, to demonstrate that it is capable of performing its intended function in addition, Item c.
requires that each MOV be stroke tested at no-pressure or no-flow conditions (static testing) to verify that the MOV is operable even if testing with a differential pressure or flow cannot be performed.
PI-10," Static Testing," establishes guidelines for developing unit-specific test procedures for performing static condition testing of MOV's.
PI-l1," Determination ofIn-Situ Test Capability," establishes the methodology and requirements for determining in-situ testability of MOV's at design-basis conditions. In addition, it establishes the 47
Millston) Unit 3 MOV Program October 6,1995 requirements for documenting and justifying those cases where in-situ testing cannot be practicably performed at design-basis conditions (see Calculation 89-094-1017M3, Rev. O, dated June 27,1995,
" Determination ofin-Situ Test Capability of Millstone Unit 3 MOV's."
Test procedures for in-situ design-basis verification testing are developed using established unit and i
station procedures and guidelines. PI-12," Requirements for Design Basis Verification Testing,"
lists parameters which must be measured during the performance ofin situ tests.
The test procedures contain the test methodology, controls, and specifications for initial system conditions, test limitations, necessary differential pressures and flows, and appropriate test acceptance criteria. MOV and system parameters such as motor voltage, upstream and downstream pressure, flow, and ambient temperature are documented in pre-and post-test data sheets.
j 11.2 Extrapolation of Partial d/p Thrust Measurements Uncertainty in predicting thrust required at design-basis d/p increases as one departs from testing at
)
100% d/p. This is a generic issue for gate valves, and to a lesser degree globe valves. Virtually all Heensees have used extrapolation, typically from 50% of design-basis d/p. The NRC has reviewed and found this practice acceptable for GL 89-10 closure." NU has also reviewed an evaluation of the extensive EPRI test results for gate and globe valves which validated linear extrapolation.22 Published EPRI results demonstrate that the friction coefficient for stellite-on-stellite decreases with increasing disc-to-seat contact pressure, i.e., increasing d/p. Thus, extrapolation from low d/p should be conservative. it is possible that contact stresses become so low that data scatter becomes significant.
We are using extrapolation approaches identical to that reviewed and accepted by NRC for other licensees. The approach is incorporated in a dynamic test methodology in accordance with PI-13,
" Evaluation of Dynamic Test Results."
11.3 Load Sensitive Behavior Rate of Loading (ROL) or load-sensitive behavior, as it is also called, is the condition where torque switch trip occurs at a different thrust under dynamic conditions than during static conditions for the same torque switch setting. For example, an MOV that achieved 20,000 lbs. of thrust at torque 4
switch trip during a static test delivers only 17,000 lbs. under dynamic conditions. This effect is normally considered as " positive" ROL, since a positive allowance is needed to ensure sufficient thrust under dynamic conditions. " Negative" ROL has also been observed, where mars thrust is delivered under dynamic conditions than static conditions. Some changes in torque as a function of loading profile may also occur. Equation 4 is used to determine ROL:
Thrust,wm - Thrust g
agu,,
Equation 4: ROL =
Thrustgrun The mechanism that produces ROL is not well understood in the industry. It appears to be related to a change in stem factor brought about by changes in stem coefficient of friction as a result of stem lubrication. During gradual loading (dynamic conditions) stem lubrication is mostly in a boundary regime. During a rapid load increase (static test) some hydrodynamic lubrication appears to exist which decreases the coefficient of friction. During the past several years ROL has been the subject 48
. - ~
Millstons Unit 3 MOV Program October 6,1995 of numerous industry presentations, discussions, and experiments. ROL was examined during the EPRI Performance Prediction Program in an attempt to quantify it. EPRI concluded that ROL was not analytically predictable.
ROL is accounted for by two methodologies, dependent upon control circuit logic. Testable MOV's are evaluated for ROL as a part of the PI-13 dynamic test evaluation. If present, the ROL will be incorporated in a revision to the thrust calculation. Both positive and negative ROL are considered.
Positive ROL increases the minimum required thrust to close the valve while negative ROL decreases the maximum allowable control switch trip values.
More consideration must be given to those MOV's which are not dynamically testable. Millstone Unit 3 has 49 MOV's in this category. Of these,10 are controlled by limit switches and require no separate specific margin for ROL. The remaining 39 MOV's all have a specific 10% margin for ROL added to their required thrust. Table 15 above (see page 39) provides the measured rate of I
loading values.
For non dynamically testable torque switch controlled valves, an additional margin (e.g., the 10%
noted above) is added to the calculated required thrust. Rather than use a representative but arbitrary margin allowance of 10%, we have validated this assumption by the use of ROL data obtained from Millstone Unit 3 dynamic test results. We have not chosen to use multi-plant data because our testing has shown that ROL is affected by the base oil viscosity of the grease used for stem lubrication and lubrication practices. A statistical analysis" was performed of this data. To provide a conservative evaluation of this data, a "trtmcated" normal distribution was used (see Figure 1, page 49). The method is well described in statistical literature." This method eliminates all negative ROL values. This will result in a higher mean and a lower standard deviation than the use of a normal distribution.
The results of this evaluation provided a mean of 6.7% and a standard deviation of 5.1%, for a 95%
confidence level that the ROL is less than 16.6%. This ROL value is combined with other sources of uncertainty using the methods outlined in Reference 24. This method uses the mean as a margin in addition to all other margins, and two standard deviations are combined with the existing errors of diagnostic system accuracy and torque switch repeatability using the Square Root Sum of Squares (SRSS) method. The result is the equivalent of a " margin multiplier" slightly less than 10%,
validating our previous 10% margin allowance.

Millstone Unit 3 MOV Program October 6,1995 1
For MOV's that are controlled by limit switches, e.g., open direction, limit seating, and close torque switch bypass schemes, ROL is accounted for by the assumed stem-to-stem nut coefficient of friction.- In this case, a separate margin is not added to the calculated minimum required, the margin is included in the assumption for coefficient of friction. In this case, the validity of the assumption is verified along with the validation of coefficient of friction.
{
It is felt that current setup practices are sufficient to provide assurance of the ability of non-testable valves to perform their intended safety function. Conservatisms are already included in the calculation of minimum required thrusta. These include conservative valve factors, diagnostic system inaccuracy, torque switch repeatability, worst case difTerential pressure, derated motor torque, theoretical packing loads, actuator application factors, worst case undervoltage factors, and stem-to-stem nut coefficient of friction.
l 11.4 Post-Maintenance Testing I
Post-maintenance testing and lubrication requirements are defined in PI-14," Post-Maintenance l
Testing and Lubrication Requirements," for MOV's which have completed a baseline set-up with i
diagnostic test equipment. Maintenance or modifications that affect the ability of an MOV to perform its design-basis function must be followed by a new baseline static test in accordance with l
GL 89-10 requirements. Listed in Table 18 are the retest requirements for various maintenance j
items. The Unit MOV Coordinator may modify these requirements when written justification is provided to demonstrate the activity does not effect the ability of the MOV to perform it's design-l basis function.
For testable valves, a dynamic test is performed at greater than or equal to 50% of design-basis differential pressure and 80% of design-basis flow conditions, following any modification which l
could affect the valve factor. Machining of the seat, disc or disc guiding surfaces, when not per the original design, is evaluated by engineering to determine if the baseline dynamic test is required. If plant or system conditions do not allow a dynamic test to be performed, an analyticaljustification is j
provided which verifies the ability of the MOV to continue to perform its required functions.

12. Diagnostic Test Equipment Accuracy i
4 12.1 GL 89-10 Supplement 5 l
On October 2,1992, Liberty Techno!ogies, manufacturer of the VOTES system used at NU, issued a 10 CFR Part 21 notiGeation regarding potential inaccuracies in thrust measurements made with l
VOTES. On June 28,1993, the NRC issued Supplement 5 to inform licensees of a generic concern i
regarding the accuracy of MOV diagnostic equipment. Liberty Technologies determined that two new factors can affect the thrust values obtained with its VOTES equipment. Those factors involve:
(1) the stem material constants, and (2) the failure to account for a torque effect when the equipment is calibrated by measuring strain of the threaded portion of a valve stem. The Supplement requested l
that the licensee evaluate this new information and any other information reasonably available to them and provide a written response to two requests for additional information. NU provided the additional information in a letter dated October 14,1993."
i
\\
NU uses Liberty Technologies VOTES diagnostic test equipment to conGrm and maintain GL 89-10 i
MOV torque switch and / or limit switch settings. NU also uses VOTES 2.31 software, which automatically calculates the torque correction factor (TCF), which accounts for the VOTES Part 21 thrust under-prediction measurement inaccuracy. The following is a summary of the actions taken to 3
address the diagnostic test equipment accuracy concern:
l (1) The Millstone Unit 3 performed VOTES thrust underprediction evaluations on July 12,1993. This effort corrected as-left measured thrust values. Internal reportability evaluations were issued to address potential valve structural over-thrusts which were successfully resolved and the valves were deemed operable.
(2) NU's Engineering Department verified that all MOV measured thrust values were proper and valid.
(3) CYAPCO and NNECO's Engineering Department instituted VOTES Part 21 thrust under-prediction corrections for all MOV thrust window calculations 4
4 51
Millstone Unit 3 MOV Program October 6,1995 completed after January 1,1993. Thrust windows incorporate the Liberty Technologies VOTES accuracy adjustment or TCF in their combined accuracy determinations. All VOTES diagnostic test systems now utilize Version 2.31 software, which automatically determines TCF. All VOTES test personnel are 4
properly trained in the use of the 2.31 software.
(4) CYAPCO and NNECO revised the MOV Program Manual stem thrust procedure to incorporate Liberty Technologies VOTES.cystem TCF accuracy corrections.
All program thrust calculations automatically address VOTES measurement and system accuracies.
(5) During Millstone Unit 3 refueling outage 4 (1993) those valves exhibiting an over-thrust condition, due to the application of the VOTES Part 21 correction, were retested and their thrusts reduced to acceptable levels.
(6) NNECO identified and evaluated historical VOTES tests to determine if previous operating thrust setups were higher and determine if cumulative fatigue is a concern. Our evaluation corrected as left thrust values and resulted in further evaluations to address potential valve structural over-thrusts. A detailed structural analysis was used to increase the valve's nominal thrust to greater than the over-thrust value and, subsequently, the valves were deemed operable.
Detailed structural analysis for the over-thrusted valves revised the allowable design thrust. The revised thrust value for unlimited cycles exceeds the maximum thrust developed during past operation, when the thrust was under-predicted.
12.2 Diagnostic Test Equipment Requirements PI-15," Requirements for Test Equipment," establishes the requirements and optional parameters to be measured by MOV diagnostic test equipment. As a minimum, diagnostic test equipment will have the capability of measuring and recording the following parameters:
Stem Thrust - measured or calculated in both the opening and closing directions.
Stem Torque - measured in both the opening and closing directions (VTC is closed only).
Limit, Bypass, and Torque Switch Actuation
Motor Current Voltage e
PI-IS specifies diagnostic test equipment calibration and system accuracy requirements. In addition, it provides general guidelines for test equipment associated with the NU MOV Program. Typically, systems and components are used from Teledyne Brown Engineering (QSS), Liberty Technologies (VOTES, STS - stem torque sensors), and calibrated strain gages. Millstone Unit 3 uses the VOTES diagnostic equipment to set the torque switches and perform diagnostic evaluations for MOV's in the GL 89-10 program.

12.2.1 Determining Accuracles 1
Minimum and maximum thrust requirements include margin for MOV test equipment accuracies as summarized in Table 19, with additional discussion below. These margins are combined using the square root of the sum of the squares method.
e Table 19: Test Equipment Accuracy Matrix Parameter Accuracy VOTES Diagnostic Test Equipment Close: 19% x TCF Open: i10% x TCF Teledyne Quick Stem Sensor (Torque and Thrust) 19.8 %
Limitorque Torque Switch Settings above #1 and 5 50 ft-lbs at TST t10%
Limitorque Torque Switch Settings above #1 and > 50 ft-lbs at TST t 5%
Limitorque Torque Switch Settings at #1 and > 50 ft-lbs at TST i10%
Limitorque Torque Switch Settings at #1 and 5 50 ft-lbs at TST i20%
A diagnostic test equipment (e.g., VOTES) closed accuracy of 9% x Torque Correction Factor (TCF) and open accuracy of 10% x TCF is assumed for the purpose of target thrust calculations based on Curve Fit Accuracy (CFA) calibration for the VOTES software, unless the testing is done outside the bounds of the Liberty assumptions. If outside the bounds, we contact Liberty to obtain the correct values, in cases where Best Fit Straight Line (BFSL) calibrations must be utilized, if the RSQ value is less than 0.997, the target thrust is recalculated to account for the difference in accuracy obtained via the CFA and BFSL methods.
The actual diagnostic test equipment accuracy used in post-diagnostic test analysis is taken from the calibration results obtained during performance of station specific procedures and / or the test equipment vendor manual, as appropriate. The calibration process may require technical guidance from the test equipment manufacturer to account for local physical variations or particular valve installations.
Any pressure measuring devices, permanent or temporary, used for determining system differential or line pressure during diagnostic testing have a minimum accuracy of 2% of the full scale reading.
The pre-diagnostic test analysis assumes a 2% pressure instrument accuracy.
Based upon Limitorque specifications, the actual torque output for a given torque switch setting is repeatable within the values specified in Table 19. This repeatability of actuator output is applied to the allowable thrust / torque at torque switch trip as well as to the total allowable torque / thrust value which includes inertial effects after contactor dropout and minimum available thrust. The measured test values are compared to these adjusted limits.
12.2.2 Applying Accuracies Diagnostic and test equipment accuracy factors are applied in a conservative manner to the calculated allowables and / or measured torque and thrust values, as appropriate. The overall accuracy which is applied to the MOV thrust and torque values will be the square root of the sum of the squares of the torque switch repeatability accuracy and diagnostic equipment accuracy.
Pressure instrument (gages or transducers) accuracy factors are applied directly to the appropriate calibration range of the pressure instrument (e.g., percentage of full scale reading, percentage of reading, etc.) and added or subtracted to the measured test pressure in accordance with PI-13. It is i
53
Millstone Unit 3 MOV Program October 6,1995 -
important to note that pressure instrument accuracies are independent of the actual reading since they are a function of the full scale reading for a given instrument, unless the accuracy is expressed as a percent of reading. If pressure transducers are used it is important to use the total loop accuracy to the point where the data is being used. Corrections for elevation-head differences between installed or temporary pressure instruments and the valve are applied in accordance with PI-13 for dynamic 4
test evaluations.
Any other combination ofindependent accuracy factors will be compiled using the square root of the sum of the squares method.
12.2.3 Limit Switch Repeatability The objective of the analysis " Millstone Unit 2 Repeatability Statistical Evaluation,"2
~
was to determine, at the 95 / 95 probability / confidence level, the repeatability of the limit switches for the Millstone Unit Two feedwater valve's closure from tests conducted at the site on October 6,1993.
The time from applying power to the motor on the MOV to the time when the limit switch was activated was measured on all four valves: 2-FW-38A,2-FW-38B,2-FW-42A and 2-FW-42B. In addition, valve closure tests were performed on 1-MS-5 at Millstone Unit One on March 16,1994.
Each of the four feedwater (FW) valves were subjected to five test runs of the valve motor until the limit switch was activated. The results of these tests consisted of times to closure and were recorded.
In addition, ten test runs of the valve motor were performed on 1-MS-5. The test results were j
recorded.
It is assumed that each measured valve closure time constitutes a random value from the population j
of all measurements. Sequential measurements on a valve are also assumed to be statistically independent and unbiased. The calculation method consisted of a sequence of steps:
4 j
1. The measurements for each valve were adjusted (transformed) by their respective mean values.
2.
Basic statistics were determined for the adjusted data.
3. The W-test was applied to verify that the data can be characterized by a normal 1
distribution (Millstone Unit 2 data only).
t
4. Two-sided 95/95 probability / confidence values for the adjusted valve closure times were determined.
5. The repeatability error for motor-operated valve closure times was then established by transforming the 95/95 values for adjusted valve closure times back to the original (pre-adjusted) times.
The most adverse 95/95 closure time for the five valves was used to specify the repeatability error as a percent of average closure time. The calculation concluded that the Millstone Unit One valve was bounded by a limit switch repeatability 10.2% and the Millstone Unit Two valves were bounded by a10.5% limit switch repeatability.
13. Grouping t
In GL 89-10 and its supplements, the NRC scaff requested that licensees test each MOV under design-basis differential pressure and flow conditions where practicable. However, the staff 7
recognized that it is not practicable to test each MOV within the scope of GL 89-10 in-situ dynamic 4
54
Millstone Unit 3 MOV Program October 6,1995 conditions. Therefore, if a licensee does not perform prototype testing at a test facility for each MOV that is not practicable to test in situ, the licensee will have to group MOV's that are not practicable to test in a manner that provides adequate confidence that the MOV's are capable of performing their design-basis function.
The staff continues to recommend testing MOV's under design-basis conditions where practicable.
Paragraph 1 of GL 89-10 allows licensees to propose alternatives to the recommendations of the generic letter wherejustification is provided. Grouping data from design-basis differential pressure testing of similar MOV's at or near design-basis test conditions is an acceptable option to establish design-basis valve setup conditions.
Grouping of MOV's is performed in accordance with the requirements of GL 89-10 Supplement 6 as summarized below: identical valve design ( the valves must either be ofidentical design orjustified identical in design by performing a detailed analysis including consideration of internal dimensions and clearances), representative (but not similar) operating conditions, the MOV's have similar installation conditions and orientation, the adequacy of the valve design has been verified through review ofindustry and plant specific data, and number of times the valve is stroked during an operating cycle.
Dynamic testing shall be performed on at least two MOV's from a group or 30% of the group (round up to the next high number of valves when taking percentages), whichever is greater. Dynamic testing need not be performed on the remaining MOV's in the group for GL 89-10 closure.
Grouping analysis methodology is contained in PI-l1. The valves exempted from dynamic testing meet the requirements of PI-11, Section 3.4; GL 89-10, Supplement 6 for excluding testable valves from dynamic testing; and the following guidelines for grouped valves:
Industry or plant specific data shows that valves in this group can perform their intended function.
]
At least two (2) and no less than 30% of the number of valves in the group will be
+
tested at or near DB conditions.
All valves in the group have been statically tested.
Valves in same group with higher priority, least margin, or greatest safety e
significance have been dynamically tested.
The MOV's have similar installation conditions and orientations.
Valve designs are the same or similar.
Adverse performance results were reviewed for applicability to all MOV's in the group.
Valve maintenance histories were reviewed to determine if valve internals are in the same condition, Millstone Unit 3 MOV's which were grouped are indicated in Table 8.

Millstone Unit 3 MOV Program October 6,1995
14. Periodic Verification 14.1 Philosophy The purpose of GL 89-10 was to ensure that safety-related MOV's are operable, and to the extent practical this has been verified by testing the MOV's at conditions representative of their design-basis function. The unit's licensing basis requires that these valves are operable and be maintained j
as operable after the closure of the design-basis verification phase of GL 89-10. There needs to be high confidence that degradation will not occur so as to erode margin or in some way render the MOV inoperable.
.l item J. of GL 89-10 speaks of the need to verify "MOV switch settings because of the effects of wear or aging"(Item d.). In Item J., the licensee is requested to perform periodic testing with surveillance intervals " based upon the licensee's evaluation of the safety importance af each MOV as well as its q
maintenance and performance history. The surveillance interval should not exceed five years or -
three outages, whichever is longer, unless a longer interval can be justified for any particular MOV."
. Millstone Unit 3, through implementation of the NU MOV Program, is committed to maintaining these safety-related MOV's operable in accordance with our MOV Program requirements as specified in our MOV Program Manual. Periodic testing can include static, dynamic, and motor current tests, or other acceptable diagnostic test methods. NU believes that static tests are fully effective in detecting degradation, except where valve internals have been modified or somehow degraded. We are aware that issues still exist as to the need to periodically dynamically test GL 89-10 MOV's. This was responsively considered in our approach to periodic testing (see Section 14.3).
14.2 Determination and Maintenance of Correct Switch Settings item d of GL 89-10 requires licensees to prepare or revise procedures to ensure that correct switch settings are determined and maintained throughout the life of the plant. PI-8," Control of MOV Settings," establishes the methodology for controlling changes to maximum and minimum thrust and torque settings, limiter plate sizes, limit switch setpoints, and thermal overload heater settings.
NGP 6.10,"Use of the PMMS Data Base to Indicate Quality Assurance or Special Program Applicability," provides methods for identifying which nuclear plant components have special program requirements. All MOV's within the scope of the MP3 MOV Program are included in a "special programs" PMMS screen. This action will provide a mechanism for identifying components which have special MOV Program requirements during the generation of Automated Work Orders or system reviews. This effort integrates the MOV Program as an element of the NU Configuration Management Program to help maintain the configuration management of MOV switch settings.
PEP Action Plan 2.3.2," Design Control Manual," has been established to redesign the design control process at Northeast Utilities. This effort is integrated with PEP Action Plans 2.3.1," Configuration Management," and 2.3.3," Engineering Programs." The Design Control Manual will provide a mechanism for ensuring that MOV design requirements are maintained.
56
Millstone Unit 3 MOV Program October 6,1995 14.3 Position on Periodic Testing (Post Closure)
The MOV Program approach to periodic testing of GL 89-10 MOV's is as follows:
1. Post-Maintenance Testing This will be performed as required by PI-14," Post-Maintenance Testing Requirements," which addresses the need for both static and dynamic testing.
2. Trending This is described in PI-16,"MOV Tracking and Trending Program." This PI will be enhanced by a revision to specify trending requirements in even greater detail. We consider the use of static diagnostic testing to be the core of an effective periodic testing program. It allows detection of anomalies and / or early indication of degradation. Periodic static testing will be performed on all GL 89 10 MOV's.
Frequency of periodic static testing will be based on the PRA ranking, with the MOV's being divided into two groups. Priority I will consist of MOV's with a "very high" or "high" PRA ranking; and Priority 2 will consist of MOV's with a " medium" or " low" PRA ranking. The definition of"very high","high", etc. is as defined by NU's Safety Analysis Branch. The frequency of testing will be:
Priority 1: Every three outages or five years, whichever is greater.
Priority 2: Every six outages or ten years, whichever is greater.
Grouping will also be employed to optimize the tested population.
3. Periodic Dynamic Testing Plans currently call for six supplemental dynamic tests to be performed over the next three fuel cycles to verify that design-basis capability is being maintained.
MOV's will be selected with consideration of margin, safety importance, maintenance history, and other relevant considerations. The figure of six tests was determined independent of the number of GL 89-10 MOV's for the nuclear unit. These tests will be evaluated, along with other industry data which is then available to determine whether degradation, not detectable with static testing, is occurring.
These plans will be reassessed when the recently announced NRC generic letter on periodic verification is issued, and changes made if deemed appropriate.
Millstone Unit 3 will be reviewing valves with low (but acceptable) margin as potential candidates for either reclassification from periodic testing category Priority 2 to 1, or to have their torque switch settings increased at the next convenient opportunity, as appropriate.

15. Trend and Analyze MOV Failures 15.1 Tracking and Trending Requirements Item h. of GL 89-10 requires that each MOV failure and corrective action taken, including repair, alteration, analysis, test, and surveillance, should be analyzed orjustified and documented. The documentation thould include the results and history of each as-found deteriorated condition, malfunction, test, inspection, analysis, repair, or alteration. PI-16, "MOV Tracking and Trending Program," establishes the tracking and trending requirements for the NU MOV Program. PI-16 requires that each MOV failure and corrective action taken, including any repair or alteration, shall be entered into the NPRDS data for their units to identify any trends.
All corrective work on MOV's is performed through the work request process. Procedures describe the method for documenting failures or nonconforming conditions that occur during operation, testing, or maintenance. Depending on the particular failure or deteriorated condition, follow-up action may include:
i Generation of a Adverse Condition Report (ACR), which replaced Plant incident e
Report (PIR).
Performance of a Root Cause Determination (RCD).
Notification under the Nuclear Plant Reliability Data System (NPRDS).
Generation of an additional work package (s) for follow-up or corrective maintenance.
15.2 Diagnostic Parameter Trending MOV performance is trtnded to ensure that switch settings remain adequate for a given MOV throughout the life of the unit. PI-16 provides guidance on the collection of as-found testing and the collection of diagnostic test data for trending. The following performance parameters shall be trended:
Motor running current and supply voltage at the MCC or at the motor, Measured maximum thrust or torque (whichever parameter is used for " baseline") at e
close torque switch trip and running average.
Power factor (if found to be a quantitative parameter, otherwise motor power should be trended).
Torque switch settings.
Valve stroke time is monitored and trended by existing nuclear unit In-Service Test (IST) Programs and will not be trended by the NU MOV Program. Our program should provide sufficient data to identify degraded MOV performance. During this RFO (1995) and last RFO (1993),143 valves had baseline static tests performed and, effectively,71 valves had baseline dynamic tests performed, including grouped valves.
58
Millstone Unit 3 MOV Program October 6,1995 15.3 MOVFailure Trending Using NPRDS The NPRDS system will be used to assist in root cause investigations of MOV failures. At least once every refueling cycle (i.e., every two years or after each refueling outage), a Component Failure Analysis Report (CFAR) will be generated from the NPRDS data on record for Millstone Unit 3 to identify trends related to MOV operability as a function of the failures reported in the nuclear industry. This effort will assist in determining areas for programmatic improvement.
16. Pressure Locking and Thermal Binding 16.1 NRC Position The NRC Office for Analysis and Evaluation of Operational Data (AEOD) completed AEOD Special Study AEOD/S92-07 (December 1992)," Pressure Locking and Thermal Binding of Gate Valves."
The staffissued the AEOD report in NUREG-1275, Volume 9 (March 1993)," Operating Experience Feedback Report Pressure Locking and Thermal Binding of Gate Valves." In its report, AEOD concluded that licensees had not taken sufficient action to provide assurance that pressure locking and thermal binding will not prevent a gate valve from performing its safety function.
A memorandum dated December 20,1993, from James T. Wiggins, Acting Director, Division of Engineering, NRR, to the Regions provided guidance on the evaluation oflicensee activities to address pressure locking and thermal binding of gate valves. Supplement 6 to GL 89-10, dated March 4,1994, provided information on the consideration of pressure locking and thermal hindin of gate valves. Finally, on August 17,1995, NRR issued GL 95-07," Pressure Locking and Thermat Binding of Safety-Related Power-Operated Gate Valves."
The NRC regulations require that licensees design safety-related systems to provide assurance that those systems can perform their safety functions. In GL 89-10, the staff requested licensees to review the design bases of their safety-related MOV's. In complying with the NRC regulations,"...
licensees are expected to have evaluated the potential for pressure locking and thermal binding of gate valves and taken action to ensure that these phenomena do not affect the capability of MOV's to perform their safety-related functions. If a licensee identifies a potential for pressure locking and thermal bindiq of gate valves, the NRC regulations require that the licensee take action to resolve that problem."
16.2 PLTB Evaluation The initial review of the potential for pressure locking and thermal binding of gate valves at Millstone Unit 3 was performed by Stone and Webster Engineering Corporation (SWEC) in 1990.28 Stone and Webster performed similar evaluations for the other Millstone Units and Haddam Neck.
During an NRC evaluation of the GL 89-10 Program at Millstone Unit 1, the NRC reviewed the 2
SWEC report, and identified potential deficiencies with the evaluation " and questioned the following assumptions:
Excluding steam system valves from the evaluation for pressure locking, Excluding valves below 200'F for thermal binding and below 150 psi for pressure locking.
59
Millstons Unit 3 MOV Program October 6,1995 Since the same assumptions were used in the Millstone Unit 3 evalration, the SWEC naluation was revisited. During the re-evaluation, the following Adverse Condition Reports (ACR's) were initiated when there were indications of PLTB concerns with GL 89-10 MOVs: ACR's 00220 (2/27/95),
00288 (3/10/95),00290 (3/14/95),00935 (3/17/95),00302 (3/25/95),00300 (4/17/95), and 03624 (6/14/95).
All ACRs were dispositied with all of the subject valves found to be operable. Final evaluations i
were performed in accord see with PI-20,"MOV Program Pressure Locking and Thermal Binding j
Evaluation", and documenicd la calculation 95-ENG-1129M3, "MP3 - MOV Pressure Locking and Thermal Binding - PI-20 Evaluations", Rev. 0 with Calculation Change Notices 1,2, and 3,
]
June 16,1995, 1
16.2.1 Evaluation Criteria The following criteria were used to determine if a GL 89-10 valve is susceptible to either pressure locking or thermal binding:3
~ Pressure locking and thermal binding is only applicable to gate valves. Any valve e
that is not a gate valve is excluded from any further evaluation for susceptibility to pressure locking or thermal binding.
Pressure locking and / or thermal binding of a gate valve is only a safety concern when the valve is closed and the valve is required to open to perform its safety function. Valves that are normally open and must only be closed to perform their safety function are not required to be evaluated for pressure locking or thermal binding.
Double-disc parallel-seat gate valves are not subject to thermal binding due to their disc design. The wedging mechanism between the double discs collapses as the nem rises. This permits the parallel discs to move inward and be raised regardless of the change in system temperature.
Solid wedge gate valves are not subject to pressure locking since the disc does not contain a cavity at the seating surfaces that can be pressurized, and simultaneous leak tightness of both disc sealing surfaces cannot be reliably achieved.
- Gate valves that perform non-design basis event opening for recovery from mispositioning only are excluded from this evaluation.
16.2.2 Evaluation Method Utilizing the above criteria, each of the valves in the GL 89-10 program have been screened for susceptibility to pressure locking and thermal binding. No further evaluation was required for valves eliminated based on one of the above screening criteria. For each valve that was not eliminated as a result of the screening, the following evaluation method was used:
The expected range of upstream and downstream operating conditions was established.
Each stroke in the Design Basis Review (DBR) calculation where the valve i:.
required to open from the full closed position was reviewed to determine if the 60
Millstone Unit 3 MOV Program October 6,1995 conditions necessary to cause pressure locking or thermal binding of the dise exist 1
during that stroke. Recovery from mispositioning strokes were not included in this
eview.
The survciliance procedures that affect these valves were reviewed to determine if the surveillance procedure established the conditions that could result in pressure j
i locking or thermal binding of the valve.
The following are the conditions that must occur before the valve is required to open for pressure j
locking or thermal binding to potentially exist:
Thermal binding of a valve could occur if a valve is closed when hot and then cools down appreciably before it is required to open. PI-20,"MOV Program Pressure Locking and Thermal Binding Evaluation," provided the temperature changes for evaluation. The valve body and seats contract a greater amount than the disc causing
~j the seats to bind the disc more tightly, increasing the force required to open the valve, possibly exceeding the capabilities of the motor operator.
j Pressure locking could occur if a valve is closed in a system that cperates at pressure e
j or is pressurized. The bonnet cavity and the area between the valve discs fili with pressurized water, equalizing with system pressure over time. Subsequently, before the valve is required to open, the system pressure drops and the higher pressure fluid is trapped in the bonnet area and the area between the valve discs. The pressurized fluid forces the discs closed even tigl' trapping the pressurized fluid and j
preventing it from leaking by the discs. When the valve is required to open, the extra force required to open the valve due to the discs being pressed against the 1
valve seats could potentially exceed the capability of the motor operator.
1 Pressure locking could occur if a valve is closed ir a system that is normally filled l
and slightly pressurized. The bonnet cavity and the area between the valve discs fill with water, equalizing with line pressure over time. (Note that the head of water from a filled tank can provide enough pressure to fill the valve internals.)
t Subsequently, before opening, the valve is heated by hotter fluid on either side of the valve disc or by an external heat source. Heating of the water in the bonnet and disc cavity results in the thermal expansion of the trapped fluid, increasing the pressure seating the valve discs against the seats. When the valve is required to open, the extra force required to open the valve due to the discs being pressed against the valve seats could potentially exceed the capability of the motor operator.

16.3 Evaluation Results For each valve opening stroke or surveillance procedure where the potential for either pressure p
locking or thermal binding exists, the corrective actions taken to preclude it from occurring are identified. The results / conclusions and corrective actions are summarized in Table 20.

The NRC regulations require an analysis under 10 CFR 50.59 for any valve modifications and establishment of adequate post-modification and in-service testing of any valves installed as part of the modi 6 cation. For example, the licensee would have to evaluate the effects of drilling the hole in the disk if used to resolve a pressure locking concern. One consideration in this evaluation is the fact that the MOV will be leaktight in only one direction. The Millstone Unit 3 Safety Analysis was documented in Millstone Unit 3 PDCR MP3-95-020.34 If an MOV is found to be susceptible to pressure locking or thermal binding and the licensee relies on the capability of the MOV to overcome pressure locking or thermal binding, the staff will review the licensee justification during inspections in consideration of the uncertainties surrounding the prediction of the required thrust to overcome these phenomena. If the staff 0nds that a licensee has not adequately addressed the potential for pressure locking and thermal binding of gate valves, enforcement actions and schedules for response will depend on the safety signincance of the issue at the plant. At Millstone Unit 3 modiGcations were made to four valves: 3CHS*MV8507A/B, 3RilS*MV8701C, and 3RHS*MV8702C, we did not have to rely on MOV capability calculations to overcome pressure locking or thermal binding. Acceptable to the NRC,35 two valves 64
Millstona Unit 3 MOV Program October 6,1995 (3RHS*MV8701 A and 3RHS*MV8702B} are currently relying on MOV capability to overcome a pressure locking condition, i.e. operable.3 This operability condition is until an acceptable physical modincation will be performed during RFO 6. Four valves,3 MSS *MOVl8A/B/C/D, are currently relying on a procedure change to prevent pressure locking and thermal binding. A physical modincation will be performed during RFO 6 for these valves.
17. Industry Information NRC information notices, industry technical and maintenance updates, and 10 CFR Part 21 notices are entered into our mainframe-based Action item Tracking and Trending System (AITfS) computer database. The assignments, due dates, required response, and resultant action can be reviewed by any individual with access to a computer.

18. Program Schedule In a letter dated June 28,1989,' the NRC Staffissued Generic Letter 89-10, " Safety-Related Motor-Operated Valve Testing and Surveillance." The letter required each licensee with an operating i
license to complete all design-basis reviews, analyses, verifications, tests, and inspections instituted to comply with GL 89-10 within five years or three refueling outages of the date of the letter, whichever was later. The required documentation had to be available within one year or one refueling outage of the date of the letter, whichever was later. The documents should include the description and schedule for the design-basis review recommended in item a. (including guidance from item e.) for all safety-related MOV's and position-changeable MOV's as described, and the program description and schedule for items b. through h. for all safety-related MOV's and position-changeable MOV's. Northeast Utilities certified in a letter dated December 15,1989,36 that they were "... developing detailed programs for addressing Generic Letter 89-10 at the Millstone Unit 3 Plant...", and that the "... programs will encompass the guidance as detailed in the Generic Letter." The proposed schedule for Millstone Unit 3, with the program denned by January 1991 and the program completed within three refueling outages (1994). 3 In a letter dated August 3,1990, the NRC Staffissued Supplement 2 to GL 89-10. In this letter, the NRC staff stated that licensees were not required to have their respective program descriptions in place until at least January 1,1991. Northeast Utilities informed the NRC in a letter dated May 4, 37 1992, that they did not fully comply with their commitments to develop program descriptions by April 1991. This conclusion was based upon an audit, part of a routine in-house Quality Services self-assessment, which determined that in-place program descriptions for addressing GL 89-10 did not contain all of the necessary technical elements specined in GL 89-10. Northeast Utilities then stated that they "... plan to have the program descriptions completed by the end of 1992." This commitment was met with the release of the Motor Operated Valve Program Manual on December 18,1992. In a letter dated December 13,1993,38 Northeast Utilities provided the NRC with an updated schedule for completion of testing at the third refueling outage (1995). This change represented a change in the Millstone Unit 3 date for the third refueling. The GL 89-10 MOV Program was completed at Millstone Unit 3 within three refueling outages after the date of the GL 89-10 letter. Additionally, documentation was provided to the NRC Staff within 30 days following the completion 65
Millstons Unit 3 MOV Program October 6,1995 of the third refueling outage. Therefore, Millstone Unit 3 has met all schedule commitments with respect to GL 89-10 requirements. l
19. Quality Assurance item f. of GL 89-10 requires that documentation of explanations and a description of the actual test methods used for accomplishing design-basis verification testing be retained. Calculations associated with design-basis reviews and development ofin-situ testing are performed in accordance with Nuclear Group Procedures (NGP) 5.05, " Design Inputs, Design Verification, and Design Interface Reviews," and NGP 5.06," Design Analyses and Calculations." All MOV Program records and test procedures are retained in accordance with NGP 2.13, " Nuclear Plant Record.: Program."
NU developed Motor-Operated Valve Engineering Program Plan, Revision 1, dated July 16,1992, to address the recommended actions of GL 89-10. The documents that implement this plan are the Motor-Operated Valve Program Manual and its Program Instructions. Based on the results of an internal audit, NU recognized that they were behind schedule in meeting their prior commitment to develop a GL 89-10 MOV Program Description for Millstone Unit 3 by April 1991. Management took action to cor ect this problem by assigning lead responsibility for MOV program development to the systems engineering group. To complete this effort, NU used contractr.'ssistance to prepare the MOV Program Instructions, differential pressure test procedures and othen r&ed documents. Northeast Utilities committed to have the Motor-Operated Valve Program Manuai i1 place by December 31,1992, and they completed this effort on December 18,1992.
20. Audits / Inspections We performed a self-assessment of our MOV Program from June 14-25,1993, following a meeting with Region I and NRR staff on May 20,1993, where we proposed our plan to do a self-assessment at the Millstone Nuclear Power Station and documented by letter, dated June 4,1993. Region I authorized our self-assessment in lieu of the NRC inspection mandated by NRC Temporary Instruction 2515/109. NRC inspectors monitored the self-assessment and found that the findings were equivalent to those that would have been identified by an NRC team. The self-assessment was conducted for the three Millstone units. The findings were significant, proper emphasis was placed on the importance of the items, and disposition of each finding was adequately addressed.
Additionally, an internal audit was conducted during RFO 5 by Quality Assessment Services personnel. The audit covered outage activities, including MOV testing, design changes, maintenance, procedure use, organization, and engineering calculations. The results of the Millstone Unit 3 Audit A30345" identified six concerns that were transferred to six Adverse Condition Reports (ACR's), in accordance with a revised QAS reporting procedure, and two recommendations for the MOV Program.
21. Training PI-17," Qualification of Personnel," establishes MOV Program training and personnel qualification requirements based on position and functional assignments. Departmental training requirements for Nuclear Group personnel are governed by NGP 2.26," Departmental Training." All personnel performing maintenance and / or testing on MOV's are required to attend and satisfactorily complete the necessary training courses. Supervisors evaluate each individual's competence and previous 66
Millstone Unit 3 MOV Progran October 6,1995 MOV experience to determine an individual's qualification to perform work. The Nuclear Training Department provides VOTES and MOV technical training for nuclear unit department personnel. Millstone Unit 3's MOV training program has been accredited by the Institute of Nuclear Power Operations. It outlines the specific requirements as well as continuing and refresher training for various technicians and engineers. This program includes both classroom knowledge and hands-on laboratory skill development. Numerous types of MOV hardware are used as training aids at the NU training facility. VOTES equipment is borrowed from Generation Test Services for training and returned for actual work at the unit. Each instructor has an individual training folder which contains qualifying documentation covering the background and qualifications of the instructor. NRC discussions with the training staff regarding MOV issues verified that they were knowledgeable and experienced. The Nuclear Training Department staff check and validate contractor training by examination requiring an 80% on a written test and a display of proficiency in the laboratory before being allowed to assist qualified personnel from Millstone Unit 3 or Generation Test Services. The Nuclear Training Department maintains a matrix of all qualified personnel in each department and distributes this information to department heads periodically. After completion of the required MOV training, the department head qualifies the trainee with applicablejob related training. The completed training information is sent to the Nuclear Training Department to update the matrix with a qualification status and a date for requalification. Required training updates are designated on the matrix to signify when new elements of training are required. The Training Program Control Committee reviews regulatory and industry documents to determine their applicability to the licensee's MOV program. Representatives from training and maintenance meet periodically to discuss the need to modify training as a result of any new industry or vendor information.

24. Status of GL 89-10 Inspection Findings NU extensively modified its position on gec v@e f'etors in December,1993 in response to the release of the EPRI PPM test data and the issuance M NRC Information Notice 93-88." This position which was documented in January 1994 has rr,mained unchanged." The memo provided requirements for operability and design-setup for both testable and non testable gate valves.
j Validation of these valve factor criteria is required as part of design-basis closure of GL 89-10. The i need tojustify these values was reaffinned in the July 12,1994,"Sheron memo". The approach for dynamically testable valves has been to validate Vf's used for design setup by dynamic testing with appropriate allowances for uncertainties and extrapolation. For non-testable valves, validation is provided using the EPRI developed Performance Prediction Methodology j (PPM)." Due to the extensive delay in the release of PPM to the industry, NU took the pro-active ) step to hire Kalsi Engineering Inc. to provide valihtice using their KEl Gate program under their QA Program. KEl Gate is the functional equivalent of the gate valve model in the EPRI PPM program. Kalsi Engineering Inc. was the developer of the gate valve model under contract to EPRI. NU recognizes that the NRC Staffintends to formally review PPM and issue a Safety Evaluation i Report (SER). NU will examine the NRC SER when issued and reconcile any differences with KEl j Gate. The schedule for resolution is dependent upon the significance of the change, and in no case would it be later than RFO 6. This recognizes that control switch settings may have to be adjusted if j significant changes were made which would involve static diagnostic testing. Subsequent calculations for new valves, new conditions, or for those previous KEl Gate calculations which require revision will all be analyzed using the NRC reviewed version of EPRI PPM. Results of a NRC inspection of the Millstone Unit 3 MOV program on June 19-30,1995, were issued in a report dated September 11,1995. The inspection report, which included one unresolved item 1 and several inspector follow items, is under review by Milistone Unit 3 staff to determine the appropriate actions. The inspector follow items covered the same MOV Programmatic issues which were reviewed and accepted by the NRC during their closure of the Haddam Neck MOV Program" ] 1 68

+design requirements, and provides in one place sufficient information to verify GL 89-10 closure.
 This has been accomplished by deGning the Northeast Utilities Motor-Operated Valve Program as implemented at the Millstone Unit 3 Plant. Included in the report are actions taken to date, as well as descriptions of the longer-term program being implemented for on-going testing and surveillance of safety-related motor-operated valves (MOV's). This program verined and ensures MOV operability under design-basis differential pressure and How conditions.
-in November of 1985, the NRC issued Bulletin 85-03 recommending licensees develop and implement a program to ensure the reliability of MOV's in several safety-related systems.

 : 1. Purpose The purpose of this document is to summarize, in one place, closure of the design-basis phase of GL 89-10, and future changes which impact design basis considerations. It also provides the baies for MOV settings and configuration. Finally, this report serves as a living document which will be periodically revised as anc element in configuration control. This closure report will be maintained as a controlled document within the MOV Program Manual and updated as necessary.
 It is currently envisioned that this document will be reviewed after each refueling outage if changes are made which impact MOV functionality or GL 89-10 MOV design compliance. This document will not control control-switch setpoints, future test data, or calculation numbers. These and other parameters are controlled by NU procedures. Tables 6,7,10, and 17 will not be maintained as living. An example of an item which will result in a revision is a design change requiring revalidating design-basis capability.

-. procedural interfaces exist with other programs governing routine maintenance, plant design changes and modifications, corrective action programs, and identification of non-conforming materials.
 The Millstone Unit 3 MOV Program is based upon satisfying two key technical requirements. These are (1) the physical limitations of the valve and actuator based on allowable limits of subcomponents (e.g., torque limits on the actuator, thrust limits, valve component structural limits, etc.) and (2) the required differential pressure and flow environment in which the valve must function. Other effects such as operation at reduced voltage and elevated temperatures, use of proper stem factors, pressure locking and thermal binding have also been considered.

 : 7. Valve Mispositioning Millstone Unit 3 has deferred consideration of valve mispositioning in our GL 89-10 program in accordance with guidance provided in NRR memo of July 12,1994 (the "Sheron memo").' The NRC staffis evaluating the request by the Westinghouse Owners' Group that the recommendation in GL 89-10 to consider valve mispositioning be removed. The NRC Staffis preparing a Supplement 7 to GL 89-10 on the need to consider valve mispositioning as part of GL 89-10 programs at Pressurized Water Reactor (PWR) plants." If ongoing staff analyses provide adequate justification, the supplement will eliminate the recommendation for PWR licensees to consider valve mispositioning as part of their GL 89-10 programs.
 During the time while the staffis preparing the proposed supplement to GL 89-10, the staff stated that a PWR licensee may defer consideration of valve mispositioning in its GL 89-10 program.'

+Millstone Unit 3 MOV Program October 6,1995 Pump Head (lipump) is the available head of any operating pump at the appropriate now rate converted to psig by an appropriate conversion factor.
 If the subject valve's close stroke reduces the source pump flow rate to zero under its design basis conditions, then the Pump IIead is the Shutoff Head at the valve's full closed position. The nominal or design pump head curve should be used for the calculation of pump head.
 Elevation Head (Hei,y.iion) results from elevation differences between the valve elevation and any higher or lower elevation of piping / components /
 tank water levels, etc., converted to psig by an appropriate conversion factor.

 : 10. MOV Sizing and Switch Settings 10.1 Valve Weak Link Analysis NU has performed weak link analyses for all MOV's in the GL 89-10 Program. The weak link analyses have determined the thrust or torque structural capacity of each component involved in supporting the MOV opening and closing strokes.
 These analyses evaluated all structural components of each MOV which typically included the valve body, bonnet, yoke, stem, disk and appropriate flanges including bolted interfaces as a minimum.
 The allowable thrust or torque capacity of each MOV was developed using the valve vendor's weak link analysis which have been independently reviewed and in most cases supplemented by Altran Corporation of Boston, MA. Completion of the weak link analysis results in identification of the 32

Part of the structural limits developed in the weak link analyses have included allowable thrust or torque under motor actuator stall conditions.
 The purpose of this additional evaluation was to ensure the resultant increase in stall thrust output of the modified actuator would not introduce a malfunction of the MOV different than any evaluated previously in the safety analysis report. The analysis compared the thrust or torque output at stall to the MOV's pressure boundary structural capacity and confirmed the valve's pressure boundary integrity was maintained. NU believes this analysis provided assurance that if a modified actuator developed stall thrust, the pressure boundary of the MOV would not be breached.
 Conformance to the ASME B&PV Code allowable stress criteria and PI 3 requirements as well as meeting the analytical and testing acceptance criterion of all other applicable Project Instructions in NU's MOV Program Manual have confirmed both the integrity of the pressure boundary as well as the functionality of the MOV.

 .2 Valve Operator Limits Similar to the " weak link" analysis for the valve, the operator's manufacturer (i.e., Limitorque) established limiting operating parameters for the operator. Situations occurred across the industry where the operator's limits would not allow attainment of the forces required to ensure the associated valve's operation under design-basis conditions. Thus, several utilities combined resources to fund a study by Kalsi Engineering tojustify increasing the published limits.

 ' locked rotor current and to use the appropriate Limitorque operator factors and design thrust values in the Limitorque sizing equations to determine correct operstor motor sizing.
 For alternating current (AC) MOV's, a motor control center (MCC) voltage corresponding to the minimum degraded bus voltage was used to supply the motor-operated valve feeder cables. This degraded voltage was based on load flow calculations assuming a hypothetical minimum switchyard grid voltage and accident (LOCA) bus loadings in accordance with PI-4,"AC and DC Motor Terminal Voltage Evaluation."

 The cable size, cable lengths, and thermal overload and magnetic coil resistances were obtained for all of the listed 460V AC motor operated valves. Power factors for locked rotor torque conditions were obtained from Limitorque. The cables were derated to elevated temperatures, and the cable voltage drop / motor terminal voltage was calculated for each MOV. These motor terminal voltages were then used to determine appropriate motor sizing using the Limitorque sizing equation.

 .3.2 Effects of Design-Basis Degraded Voltage on MOV Performance PI-4,"AC and DC Motor Terminal Voltage Evaluation," provides instructions for performing minimal terminal voltage evaluations for AC and DC powered MOV's. This evaluation provides direct input to the motor derate output torque evaluation which is then input to PI-9," Determination of Stem Thrust Requirements," for evaluating the effects of degraded voltage at design-basis conditions.
 PI-4 uses locked rotor current at degraded voltage conditions to determine motor terminal voltage.
 Because this is beyond the current licensing basis of the Millstone Unit 3 and Millstone nuclear units, when operability issues arise,(e.g., when inadequate motor terminal voltage is predicted during the course of a degraded voltage calculation), additional MOV specific calculations will be performed with less restrictive assumptions (e.g., use of starting current).

These data points were obtained under dynamic (i.e., flow and differential pressure) conditions, to best represent design-basis conditions. As noted, all data points are below 0.15 for Haddam Neck, Millstone Unit 1, and Millstone Unit 2, and below 0.18 for Millstone Unit 3; therefore validating our assumption. To add further rigor to NU's MOV Program, we are assessing the use of statistical analysis of our final data set (post Millstone Unit I completion) as a validation methodology. This will require additional data to permit meaningful statistical analysis.

This is based on a preventive maintenance program, and using the " reservoir method" of stem lubrication, which limits degradation of stem lubricant. To validate this assumption,"as-found" dynamic tests may need to be performed unless another means of monitoring stem lubrication effectiveness statically can be developed. Currently, use of motor power to provide this capability without further dynamic testing is being evaluated. The small number of as-found tests conducted to date indicate that there is no lubrication degradation using the reservoir method, therefore validating our assumption that additional margin is not required. However, for those MOV's with small overall margin, we will continue to closely monitor for changes.

+FUS 10.8 Stem Lubrication and Springpack Relaxation The MOV Program assumes little or no degradation of stem lubricant will occur between maintenance intervals. This is based on a preventive maintenance program, and using the " reservoir method" of stem lubrication, which limits degradation of stem lubricant. To validate this assumption,"as-found" dynamic tests may need to be performed unless another means of monitoring stem lubrication effectiveness statically can be developed. Currently, use of motor power to provide this capability without further dynamic testing is being evaluated. The small number of as-found tests conducted to date indicate that there is no lubrication degradation using the reservoir method, therefore validating our assumption that additional margin is not required. However, for those MOV's with small overall margin, we will continue to closely monitor for changes.

 In addition to the ability to set the limit switch, some determination of the ability of the switch to trip at the same point each time must be made. The repeatability of the limit switches for Limitorque actuators is commonly reported at 2 to 3%. There has been no industry documentation of any testing or evaluation oflimit switch repeatability. The purpose for which we use limit switch control of valve closure on a gate valve requires better repeatability than 2 to 3%. NU has determined limit switch repeatability for particular applications based upon statistical analysis of multiple valve strokes 2 (see Section 12 2.3).
 At Millstone Unit 3, only the 46 butterfly / plug valves are set-up on limit switch control.
 .10 Torque Switch Bypass Methodology NU has implemented a methodology of bypassing the torque switch until flow cutoff. This control configuration is similar to limit-closed configuration because the full capability of the motor actuator is available to close the valve.1lowever, NU's torque switch bypass configuration differs because the limit switch removes the torque switch bypass until flow cutoff and not the motor power. This allows the motor to ensure the disk covers the flow path then fully seat the disk based on torque.

-Using this control configuration, a possibility exists during a close stroke under dynamic conditions for the motor torque to exceed the torque switch trip setpoint, which is bypassed.

 NGP 6.10,"Use of the PMMS Data Base to Indicate Quality Assurance or Special Program Applicability," provides methods for identifying which nuclear plant components have special program requirements. All MOV's within the scope of the MP3 MOV Program are included in a "special programs" PMMS screen. This action will provide a mechanism for identifying components which have special MOV Program requirements during the generation of Automated Work Orders or system reviews. This effort integrates the MOV Program as an element of the NU Configuration Management Program to help maintain the configuration management of MOV switch settings.
 PEP Action Plan 2.3.2," Design Control Manual," has been established to redesign the design control process at Northeast Utilities. This effort is integrated with PEP Action Plans 2.3.1," Configuration Management," and 2.3.3," Engineering Programs." The Design Control Manual will provide a mechanism for ensuring that MOV design requirements are maintained.

 The MOV Program approach to periodic testing of GL 89-10 MOV's is as follows:
 : 1. Post-Maintenance Testing This will be performed as required by PI-14," Post-Maintenance Testing Requirements," which addresses the need for both static and dynamic testing.
-: 2. Trending This is described in PI-16,"MOV Tracking and Trending Program." This PI will be enhanced by a revision to specify trending requirements in even greater detail. We consider the use of static diagnostic testing to be the core of an                 l effective periodic testing program. It allows detection of anomalies and / or early indication of degradation. Periodic static testing will be performed on all GL 89 10 MOV's.

 Millstone Unit 3 will be reviewing valves with low (but acceptable) margin as potential candidates for either reclassification from periodic testing category Priority 2 to 1, or to have their torque switch settings increased at the next convenient opportunity, as appropriate.

 : 15. Trend and Analyze MOV Failures 15.1 Tracking and Trending Requirements Item h. of GL 89-10 requires that each MOV failure and corrective action taken, including repair, alteration, analysis, test, and surveillance, should be analyzed orjustified and documented. The documentation thould include the results and history of each as-found deteriorated condition, malfunction, test, inspection, analysis, repair, or alteration. PI-16, "MOV Tracking and Trending Program," establishes the tracking and trending requirements for the NU MOV Program. PI-16 requires that each MOV failure and corrective action taken, including any repair or alteration, shall be entered into the NPRDS data for their units to identify any trends.
 All corrective work on MOV's is performed through the work request process. Procedures describe the method for documenting failures or nonconforming conditions that occur during operation, testing, or maintenance. Depending on the particular failure or deteriorated condition, follow-up action may include:
-i                            e   Generation of a Adverse Condition Report (ACR), which replaced Plant incident Report (PIR).

 .2 Diagnostic Parameter Trending MOV performance is trtnded to ensure that switch settings remain adequate for a given MOV throughout the life of the unit. PI-16 provides guidance on the collection of as-found testing and the collection of diagnostic test data for trending. The following performance parameters shall be trended:
-* Motor running current and supply voltage at the MCC or at the motor, e   Measured maximum thrust or torque (whichever parameter is used for " baseline") at close torque switch trip and running average.
+Motor running current and supply voltage at the MCC or at the motor, Measured maximum thrust or torque (whichever parameter is used for " baseline") at e
-* Power factor (if found to be a quantitative parameter, otherwise motor power should be trended).
+close torque switch trip and running average.
-* Torque switch settings.
+Power factor (if found to be a quantitative parameter, otherwise motor power should be trended).
+Torque switch settings.
 Valve stroke time is monitored and trended by existing nuclear unit In-Service Test (IST) Programs and will not be trended by the NU MOV Program. Our program should provide sufficient data to identify degraded MOV performance. During this RFO (1995) and last RFO (1993),143 valves had baseline static tests performed and, effectively,71 valves had baseline dynamic tests performed, including grouped valves.

 : 16. Pressure Locking and Thermal Binding 16.1 NRC Position The NRC Office for Analysis and Evaluation of Operational Data (AEOD) completed AEOD Special Study AEOD/S92-07 (December 1992)," Pressure Locking and Thermal Binding of Gate Valves."
 The staffissued the AEOD report in NUREG-1275, Volume 9 (March 1993)," Operating Experience Feedback Report Pressure Locking and Thermal Binding of Gate Valves." In its report, AEOD concluded that licensees had not taken sufficient action to provide assurance that pressure locking and thermal binding will not prevent a gate valve from performing its safety function.
 A memorandum dated December 20,1993, from James T. Wiggins, Acting Director, Division of Engineering, NRR, to the Regions provided guidance on the evaluation oflicensee activities to address pressure locking and thermal binding of gate valves. Supplement 6 to GL 89-10, dated March 4,1994, provided information on the consideration of pressure locking and thermal hindin of gate valves. Finally, on August 17,1995, NRR issued GL 95-07," Pressure Locking and Thermat Binding of Safety-Related Power-Operated Gate Valves."
-The NRC regulations require that licensees design safety-related systems to provide assurance that those systems can perform their safety functions. In GL 89-10, the staff requested licensees to        l review the design bases of their safety-related MOV's. In complying with the NRC regulations,"...

 licensees are expected to have evaluated the potential for pressure locking and thermal binding of gate valves and taken action to ensure that these phenomena do not affect the capability of MOV's to perform their safety-related functions. If a licensee identifies a potential for pressure locking and thermal bindiq of gate valves, the NRC regulations require that the licensee take action to resolve that problem."
 .2 PLTB Evaluation The initial review of the potential for pressure locking and thermal binding of gate valves at Millstone Unit 3 was performed by Stone and Webster Engineering Corporation (SWEC) in 1990.28 Stone and Webster performed similar evaluations for the other Millstone Units and Haddam Neck.
 During an NRC evaluation of the GL 89-10 Program at Millstone Unit 1, the NRC reviewed the 2
 SWEC report, and identified potential deficiencies with the evaluation " and questioned the following assumptions:
-* Excluding steam system valves from the evaluation for pressure locking,
+Excluding steam system valves from the evaluation for pressure locking, Excluding valves below 200'F for thermal binding and below 150 psi for pressure locking.

 The NRC regulations require an analysis under 10 CFR 50.59 for any valve modifications and establishment of adequate post-modification and in-service testing of any valves installed as part of the modi 6 cation. For example, the licensee would have to evaluate the effects of drilling the hole in the disk if used to resolve a pressure locking concern. One consideration in this evaluation is the fact that the MOV will be leaktight in only one direction. The Millstone Unit 3 Safety Analysis was documented in Millstone Unit 3 PDCR MP3-95-020.34 If an MOV is found to be susceptible to pressure locking or thermal binding and the licensee relies on the capability of the MOV to overcome pressure locking or thermal binding, the staff will review the licensee justification during inspections in consideration of the uncertainties surrounding the prediction of the required thrust to overcome these phenomena. If the staff 0nds that a licensee has not adequately addressed the potential for pressure locking and thermal binding of gate valves, enforcement actions and schedules for response will depend on the safety signincance of the issue at the plant. At Millstone Unit 3 modiGcations were made to four valves: 3CHS*MV8507A/B, 3RilS*MV8701C, and 3RHS*MV8702C, we did not have to rely on MOV capability calculations to overcome pressure locking or thermal binding.

Region I authorized our self-assessment in lieu of the NRC inspection mandated by NRC Temporary Instruction 2515/109. NRC inspectors monitored the self-assessment and found that the findings were equivalent to those that would have been identified by an NRC team. The self-assessment was conducted for the three Millstone units. The findings were significant, proper emphasis was placed on the importance of the items, and disposition of each finding was adequately addressed.
