INTRODUCTION:

The following information is provided in response to IES 85-03 Action Item (f),

parts 1,2, and 3; pursuant to the provisions and comaltments of Georgia Power Company (OPC) letter GN-1088 letter dated August 28, 1986 for Vogtle Electric j

GeneJating Plant Unit 1 (VEOP-1).

l PURPOSE:

The purpose of this response is to provide verification of initial program completion at VIOP-1, which includes preadjustment valve operability and test result summaries, within sixty days of testing completion in accordance with the requirements of 188 85-03.

RESPON88:

Reference 2 provided our initial response to IEB 88-03 Action Ites (e), parts 1 and 2, commensurate with our commitments and the provisions. provided la our request for extension per Reference 1.

This response specifically addresses the test results and program actions taken based on selection and testing of applicable

" active" inservice motor-operated valves in the Safety Injection, Chemical and Volume

control, and Auxiliary Feedwater systems.

Valve selections were made consistent with the Four Loop Westinghouse Pressurized Nater Reactor Nuclear Steam Supply Systen " and operational readiness

VALVE DESIGN INFORMATION (Ref.

IEB 85-03 Action Item "a")

Design differential pressure information has been amended to reflect calculations by the the Architect / Engineer and the NSSS supplier based on actual system operating requirements and limitations.

SETPOINT REQUIREMENTS (Ref.

IES 88-03 Action Item "b")

Initial program actions prompted generic separation of limit switch rotor functions for both safety and non-safety related motor-operated valve applications.

This included separation of both position indication and permissive / interlock functions with respect to the open torque switch bypass, as practicable.

Butterfly valves and HVAC dampers were excluded from generic separation in view of their behavioral differences and standard limit open, limit closed control functions.

The Auxiliary Feedwater System pump turbine steam l

1 olation and Terry Turbine trip and throttle

valves, 1HV-5106 and IPV-15129 respectively, were not changed due to more complex design change requirements.

Precedence was given to the open torque switch bypass over position indication on i

these two special case valves.

Additional actions taken included the i

establishment of interim setpoints for use in the absence of specific Westinghouse setpoint l

This criteria also provided a method of accurate open position indicatloca 'and established provisions-for open 11 alt. control. function to:

' dampers where precedence was given to. position' indication and orbit ball valves whichEhave the open torque switch bypass. set to fifty. percent'in accordance with vendor recommendations.

This criteria was selected on the basis.of providing adequate protection margin to encompass virtually all' unseating and initial opening' thrust requirements due to differential pressure effects.

This

.setpoint determination was based on comparisons of performance parameters for various valve types based on the direct relationship between pressure drop and differential pressure reduction during valve opening, q

Figure 1 shows an example of pressure drop versus percent open ratio for a typical gate valve.

It 1

can be seenLthat the. thirty percent open bypass f

provides approximately a

ninty-six percent i

reduction.

in pressure drop or practical equalization of differential pressure.

It can further be expected that. operator loads after the bypass will only be slightly higher than that required for static operating conditions.

Thus, affording optimum bypass protection and maximum torque

' switch adjustment and performance capability.

Test results indicate the interia setpoints l

established provide optimum open bypass protection 1

as well as practical position indication to assure 1

f reliable valve performance.

conditions.

The figure clearly demonstrates the validity of the open torque switch bypass with respect to differential pressure effects.

Torque switch settings for the valves selected have-been established to the extent practicable be.ed on Motor-operated Valve Analy. tis and Test Sssten (MOVATS) thrust determinations to ensure that demonstrated and/or calculated thrust requirements were met.

Long term setpoint controls have been formalized for motor-operated valves by development of a

setpoint manual.

The setpoint manual provides specific setup guidelines per valve application and valve specific setpoint criteria based on the testing results and established philosophies.

OPERABILITY TESTING (Ref.

IRB 88-03 Action Item "c")

Initial program testing for the valves identified in Table 1 has been completed.

Program testing has been. accomplished by means of " Motor-Operated Valve Analysis and Test System utilization.

This testing included comparative static and dynamic performance evaluations, to the extent practicable, to assess the ability of the operators to perform their design functions under worst case operating conditions.

Static signatures have been taken and evaluated to facilitate in the determination and correction of existing degradations.

These signatures establish comparative baseline data used in dynamic test and future performance evaluations.

Figures 3 and 4

represent typical static signatures used for performance evaluations.

Dynamic signatures have been taken, to the extent practicable, to demonstrate valve operability and have provided a means of optimizing valve setpoint criteria.

Figures 5

and 6

represent typical dynamic signatures.

Comparing the static and dynamic signatures provides insight with regard to valve setpoint optimization.

Plant Vogtle's long term program includes post-maintenance testing of motor operated valves using MOVATS or the Motor Control Center test unit as applicable to monitor valve performance and detpoint margins.

PROCEDURES (Ref. 158 88-03 Action Item "d")-

Procedures have been' developed and revised to ensure. correct switch settings.are determined and maintained throughout the life of the plant.

Initially procedures were upgraded to implement interim setpoint determinations based on providing adequate open torque switch bypass and' accurate position indication functions.

Additional action included development' of a motor-operated valve testing procedure utilizing the MOVATS 2160 test system.

Field validation in conjunction with NOVATS testing results provided means for additional procedure upgrades.

These upgrades included improved guidelines for torque and limit switch:

maintenance, adjustment, inspections, and functional.

test requirements..

. In.

addition, emphasAs has been placed on standardizing switch setting methodology and maintaining consistent switch aettings for the life of the plant.

This has been accomplished through the development of a "Notor-Operated Valve Setpoint-Manual".

The manual pro 71 des standardized setup-methodology based on application and valve specific setpoint criteria consistent with test result

findings, i

This standardization effort has been applied to both safety and non-safety related motor-operated valve applications.

Ongoing procedural development, consistent with l

future long term operability testing

plans, is currently in process to provide an additional means of monitoring valve performance and setpoint margins.

Plans include validation and final draft of the testing procedure utilizing the Motor Control Center test unit and coordination with Inservice Test Program activities for valve l

performance monitoring.

INITIAL RESPONSE / SCHEDULE (Ref.

IRB 85-03 Action Item "e")

Reference 2

provided the necessary information relative to program development and implementation plans commensurate with the initial response requirements of IEB 85-03, Action Item "e",

parts 1 and 2.

In accordance with the initial response

schedule, this response is the final report for VEGP-1.

Consistent with Reference 2,

Vogtle Electric I

TEST REPORTS (Ref. IER 85-03 Action Item "f")

This response meets the report requirements for IEB 85-03 Action Ites "f",

parts 1,2 and 3 for VEOP-1.

Static testing has been performed on 49 out of 50 valves originally identified for testing pursuant to the requirements of IEB 85-03.

The Auxiliary Feedwater System Terry Turbine Trip and Throttle

Valve, IPV-15129, has been excluded from testing due to specific operating characteristics associated with spring closure and specific design base exclusions from any requirement to open under differential pressure conditions.

Table 2

provides a matrix of the preadjustment operability findings identified during testing on VEGP-1.

A total of 22 discharge valves in high pressure system applications targeted by the Bulletin have been dynamically tested.

Suction valves were excluded from dynamic testing on the basis of the differential pressures involved and to avoid potential pump damage from unintentionally starving a pump.

Additional exclusions include the Auxiliary Feedwater System discharge

valves, used for flow control, on the basis of exemption from inservice test requirements pursuant to the provisions in the ASME

code,Section XI, Subarticle IWV 1200.

Attempts to monitor dynamic j

performance during Engineered Safety Feature Actuation System testing proved the valves were capable of operating under such conditions.

Three additional valves controlling the steam supply to the Turbine Driven Auxilliary Feedwater Pump were not able to be tested under actual l

dynamic steam flow conditions.

System alignment to achieve the maximum differential pressure conditions would have required locking closed four of five safety relief valves.

Establishment of this system condition was considered unpractical l

from a

safety and system / component integrity

)

viewpoint.

However, these three valves; 1HV-3009, j

1HV-3019, and 1HV-5106 have been setup based on 1

l Vendor supplied thrust requirements and verified l

against the MOVATS thrust equations based on seat l

orifice area, i

To the extent practical, the actual dynamic test conditions used were based on maximum achieved system pressures,. as governed by the performance capabilities of the associated equipment during system operation under simulated accident conditions.

Chemical and Volume Control System high pressure safety injection and Safety Injection System discharge valves were tested under simulated loss of coolant accident (LOCA) conditions, with the vessel at zero operating

pressure, ambient temperature, and the head removsd.

Test conditions and results are provided in Table 3.

OB8ERVATIONS:

The following general observations were made during MOVATS testing at VEGP-1:

Torque switches in general required minor adjustments, including torque switch balancing where provisions allowed, between the nominal and maximum design settings to achieve design thrust requirements.

By refering to the preadjustment operability matrix it can be seen that the torque switch balance is often out of adjustment with some cases resulting in excessive thrust or inadequate thrust during valve operation.

Some additional observations with regard to torque switches include the amount of play in the limiter plate for a

given torque switch.

This was typically found to be plus or minus 1/4 of a

setpoint.

Dependency on the limiter plate to set the torque switch to design maximum settings may lead to excessive thrust, exceeding the operator's design output.

Overall. Initial testing indicates an inherent performance tolerance of approximately 1/4 of a setpoint for any given torque switch.

Westinghouse EMD gate valves, of dual connecting pin gate to stem construction, were found to require considerably greater closing thrust than that required to open against the same differential pressure conditions.

This is not typical of standard type gate

valves, and is attributable to the two pin design peculiar to these Westinghouse valves.

The dual pin design also induces higher closing thrust requirements, but in turn reduces opening thrust requirements as compared to standard gate valves under similar differential pressure conditions.

Additionally, there were instances found where demonstrated thrust requirements, by means of full flow dynamic

testing, showed the minimuu thrust required to seat. the valve against the maximum differential pressure was greater than that specified by design.

In 'these instances the demonstrated thrust requirements were maintained.

Proper selection of the motor-operatur housing gasket thickness was found to be a

significant factor in the overall running load of an cperator.

Instances were found where the running load thrust due to improper gasket selection was as high as 3,000 pounds.

This thrust would otherwise be transfered to valve opening or closing thrust.

During testing of the Auxiliary Feedwater discharge valves the two piece ' stem connections were found to unscrew when opened under load.

This condition was noticed while attempting to have the valve torque out into a

load cell.

Design changes were implemented to utilize a

woodruff key modification such that the two piece stem connection would have a positive means of locking to prevent rotation under load.

SUNNATION:

The over-all findings from our testing to date on VEOP-1 upholds the absence of any prevalent common i

mode failure potential for motor-operated valves at Plant Vogtle.

Initial testing indicates that significant improvements in valve reliability are possible 1

through the use of signature analysis techniques, j

and that such techniques afford the means for j

fine-tuning and monitoring the performance of motor-operated valves.

Future plans at Plant Vogtle entall the continued use of valve performance j

monitoring by means of signature analysis techniques to maintain and improve valve reliability.

1l-TABLE 3:

TEST JUSTIFICATIONS Actual dynamic testing was performed based on maximum achieved pump discharge pressures, with miniflow protection in effect consistent with design based operational requirements, under simulated accident conditions.

.{I]

Actual dynamic testing was performed utilizing full pump f

discharge pressures upstream of the valves with no. system imposed downstream pressures (i.e. vessel drained down and head off),

simulating postulated line break conditions to the extent practicable.

[2]

The design pressures listed for the miniflow valves are based on pump dead head conditions.

Isolation of miniflow

)

valves is not a high head performance concern based on plant design requirements.

Actual testing of these miniflow valves were performed under high system flow i

conditions approximating those associated with design based accident requirements.

(i.e.

near pump runout conditions which approximate actual performance requirements assocated with recirculation mode isolation).

[3]

These valves were tested at maximum differential pressures higher than required by design and were found to be inoperable in she closed direction.

However, these valves were found to be operable under their design base requirements.
