(All) The purpose of this testimony is to address those issues relating to Joint Intervenors' Contention 10.5 that the
)
Atomic Safety and Licensing Board (" Board") designated for hearing in its Memorandum and Order (Ruling on Motion for Summary Disposition of Contention 10.5 re: ASCO Solenoid
) k
I Valves) issued on January 7, 1986.
As stated by the Board,
)
those issues consist of the following:
(1)
There is no information offered that permits a determination of whether any type of
):
failure of any of the valve models considered will result in achieving an unsafe configuration for the valves and/or dampers that are being controlled.
(2)
No basis is provided for the various statements about how long any of the valve I
models will be required to operate in VEGP
~
following an accident, nor is there an explanation of how it will be determined
)
that any of the valve models will indeed be capable of the specified length of operating time following an accident.
)
(3)
It cannot be determined whether the unsealed solenoid housing on one [NP 8316] valve specimen represents a quality control deficiency that can endanger VEGP operation.
)
(4)
Since no manufacturer's specifications for the various valve models are given (e.g.
acceptable operating voltage ranges, air
)-
supply requirements and acceptable leak rates) the anomalous behaviors noted are i
)
difficult to evaluate as to seriousness.
)
Likewise, the likelihood of valve leakage depending upon the duration of test conditions cannot be evaluated, y
(5)
The question of whether production models of the valves discussed may show different performance characteristics than did the
)
specimens tested cannot be evaluated, since Applicants have not addressed the subject matter of 10 CFR 50.49(e)(8) in their motion.
)
(All) In this testimony we will discuss the environmental qualification of the four models of solenoid valves manufactured by Automatic Switch Co. ("ASCO") used in safety-related applications at the Vogtle Electric
)
Generating Plant ("VEGP").
We will describe the four models of ASCO solenoid valves and will discuss their function at VEGP.
We will review the environmental
)
qualification testing that has been performed on those valves, will discuss other tests performed on those model valves by the Franklin Research Center, and will address
)
the environmental qualification of those solenoid valves for use at VEGP in light of the Franklin Research Center test results.
Finally, we will explain the basis on which the Applicants have concluded that the ASCO solenoid valves used in safety-related applications at VEGP are environmentally qualified and will operate as intended.

)
I.
The Use of ASCO Solenoid Valves at VEGP.
)
A.
The Types of ASCO Solenoid Valves Used at VEGP.
(All) Four types of ASCO solenoid valves are utilized in safety-related applications at VEGP.
ASCO designates
{
those four valve types as models NP 8316, NP 8320, NP 8321, and 206-381-6RF.
These four models are all part of ASCO's NP series of valves designed for use in nuclear
)
facilities.
Each valve type consists of several valves that have the same basic design but differ with respect to body material (brass or stainless steel), pipe and orifice sizes, configuration when de-energized (open, closed, or universal), type of solenoid housing (watertight or explosion proof and watertight), and type of el'astomer I
material (ethylene propylene or viton).
The different features of these valves are described in ASCO's Catalog No. NP-1, a copy of which is attached hereto as Exhibit F.
)
1.
The Model NP 8316 ASCO Solenoid Valve.
(All) The ASCO model NP 8316 solenoid valve is a three-way, internal pilot controlled valve with a pressure h
port, an exhaust port, and a cylinder port.
In a typical application, the pressure port is connected to a supply of pressurized air, the cylinder port is connected to the air operator of a process valve, and the exhaust port is used as a discharge vent to the atmosphere.
All of the model l
-S-l
)
I
E'
)
NP 8316 valves used in safety-related applications at VEGP
)
have a closed configuration when de-energized, which means-that the pressure port is closed and the cylinder port is connected to the exhaust port.
This configuration vents
)-
the air operator of the process valve to the atmosphere.
When the valve is energized, its internal parts realign to connect the pressure port to the cylinder port and to
)
close the exhaust port.
That allows the pressurized air to reach the air operator of the process valve, thereby actuating the process valve.
y 2.
The Model NP 8320 ASCO Solenoid Valve.
(All) Unlike the model NP 8316, the ASCO model NP 8320 solenoid valve is a three-way, direct acting solenoid j
valve.
Rather than using an internal pilot, the solenoid core position directs airflow.
In the de-energized mode, the solenoid valve core spring forces the core assembly q
j (with valve seat) down, isolating the pressure port and connecting the exhaust port to the cylinder port.
In this position, the solenoid valve allows the air operator on ij the process valve to vent.
Energizing the solenoid causes the core assembly to realign, allowing the pressurized air to pass to the air operator on the process valve and isolating the exhaust port.
)
3.
The Model NP 8321 ASCO Solenoid Valve.
(All) The ASCO model NP 8321 solenoid valve, like the i
model NP 8316 valve, is a three-way, internal pilot l \\
{
controlled valve.
This model valve operates in a manner
)-
similar to that of the model NP 8316.
The primary differences between the two valves are that the model NP 8321 valve is piston operated and its exhaust port is
)
larger than the pressure port, which allows relatively rapid venting.
On the model NP 8316 valve, all of the ports are the same size and generally larger than those on the NP 8321 valve.
Larger orifices allow higher flow rates through the model NP 8316 valve.
4.
The Model 206-381-6RF ASCO Solenoid Valve.
(All)'The ASCO model 206-381-6RF solenoid valve differs from the model NP 8316 valve in that it has no internal pilot and is a three-way direct acting solenoid j
valve.
In the model 206-381-6RF valve, the posit _ ion of the moveable solenoid core acts on a lever arm, which directs air flow.
Energizing the solenoid causes the core to lift up.
This connects the pressure port to the cylinder port and isolates the exhaust port.
When the valve is de-energized, the solenoid core falls, blocking j
the pressure port and connecting the exhaust port to the cylinder port.
B.
The Function of ASCO Solenoid Valves at VEGP.
j (GJB, SJC)
The ASCO solenoid valves used in safety-related functions at VEGP control the operation of air-operated process valves and dampers in safety-related
)
I 1
i fluid and-HVAC systems.
Those solenoid valves direct the
[
opera' tion of air-operated process valves oridampers by controlling air flow to the air operator on these valves or dampers.. ByLeither venting or providing air to the air-
):
operator on the process valve or damper, the ASCO solenoid valve enables.that valve or damper to close or open.
All of.the ASCO solenoid valves used to perform safety-related.
)..
functions at VEGP are designed to be closed when de-energized, in which position the solenoid valve would.
vent the air operator on the process valve or damper and block-the. passage of instrument air.
-(GJB,.SJC)
Figure 10.5-1 depicts the manner in which the ASCO solenoid valve controls the operation of an
[
Eair-operated process valve or damper.
Air is supplied to the air operator of the process valve or damper from the plant instrument air system through the'ASCO solenoid valve.
When the ASCO valve ~is energized, its internal J.
parts realign to allow instrument air to pass through the solenoid valve to the air operator of'the process valve or f, -
The application of instrument air to the operator increases pressure on a diaphragm in the operator-to an extent sufficient to overcome the force of a stored energy device in the operator, typically a spring, which causes
{
the process valve or damper to assume its normal position.
When the ASCO solenoid valve is de-energized, I '
I
p its internal parts are aligned to block the instrument air
)
and to connect the air operator of the process valve or damper-to the atmosphere through the exhaust port.
That allows the air pressure that had been applied to the f
diaphragm in the operator to vent, and the stored energy device in the operator causes the process valve or damper to assume its safety-related position.
)
(GJB, SJC)
The process valves and dampers performing safety-related functions at VEGP that are controlled by ASCO solenoid valves are arranged so that the process valve or damper will assume its safety-related position,
)
either open or closed, when the air operator is vented.
The safety function of each ASCO solenoid valve is to vent
)
the operator of the air-operated valve or damper with which it is associated to allow that valve or damper to move to its safety-related position.
As described above, all of the ASCO solenoid valves employed in safety-related capacities at VEGP are of the normally closed design.
When de-energized, which is its safety-related position, the solenoid valve blocks the supply of instrument air and
)
vents the air operator of the process valve or damper.
(SJC)
Table 10.5-1, attached hereto, lists each of jl the safety-related air-operated valves or dampers at VEGP controlled by an ASCO solenoid valve and identifies the model ASCO solenoid valve associated with that valve or
)

)
I damper.
That table also describes the function performed
)L by the air-operated valve or damper and its safety-related position.
C.
Manufacturer's Specifications for ASCO Solenoid Valves and Comparison to Conditions at VEGP (GJB)
One of the issues identified by the Board I
concerned ASCO's specifications with respect to acceptable operating voltage ranges, air supply requirements, and acceptable leak rates for the various models of ASCO solenoid valves used at VEGP.
ASCO's specifications for the various valve models are set out generally in Exhibit F attached hereto, which is the catalog published by ASCO for its NP series solenoid valves, including each of the four valve models used at VEGP.
)
1.
Onerating Voltage Ranges.
(GJB, SJC)
For its solenoid valves operating on direct current, ASCO specifies a nominal applied voltage of 125 volts (125 VDC), with an acceptable operating voltage range of 90 to 140 volts.
For valves operating on alternating current, ASCO specifies a nominal voltage of 120 volts of 60 cycle alternating current (120 VAC), with an acceptable operating range of 102 to 132 volts.
At VEGP, the power supplied to ASCO solenoid valves is designed to be either 125 VDC or 120 VAC, and the extreme voltage values expected on the VEGP electrical
)
rm k
distribution system are within the acceptable operating
{.
voltage ranges specified by ASCO.
2.
Air Supply.
(GJB, WVC)
ASCO's specifications require that the air y
supply to the solenoid valves be instrument quality air, which.means that it must be dry, filtered, and oil-f ree.
The operating pressure differential for the air supply
)-
must range between (a) the maximum differential pressure between the inlet and outlet sides of the valve against which the solenoid can safely operate and (b) the minimum j
operating pressure differential required for dependable operation.
The range of acceptable operating pressure differentials specified by ASCO differs for each model valve.
Those ranges are set out in Exhibit F.
.(GJB, SJC)
The VEGP air _ system provides a continuous supply of filtered, dry, oil-f ree cornpressed air for pneumatic instrument operation and control of pneumatic actuators.
The system also supplies compressed, normally filtered, dry and oil-free service air to outlets throughout the plant for the operation of pneumatic tools and other service air requirements.
The instrument and service' air system is not required for the safe shutdown of the plant.
The instrument air provided by this system is of the quality recommended in the Instrument Society of America's Quality Standard for Instrument Air, ISA-S7.3. )-
)
It is dehumidified to a dewpoint of -60* F or below and
)
filtered to remove all particles 3 microns in size and larger.
Oil content will be as close to zero as possible and is not to exceed one ppm.
The VEGP air supply system
)-
is designed for a nominal operating pressure of 120 psig.
The actual operating pressure at the ASCO solenoid valve pressure port is regulated by an air set installed in the
~
instrument air tubing upstream of the ASCO solenoid valve
)
to prevent damage to the process valve air operator.
Except for the ASCO solenoid valves used to control HVAC j
dampers, the operating pressure for the ASCO solenoid valves ranges from 20 psig to 100 psig.
For the vast majority the operating pressure would be less than 85 psig.
The operating pressure for the ASCO solenoid valves
)_
controlling HVAC dampers will be 120 psig.
These operating pressures are within the acceptable operating pressure differential range specified by ASCO for each of y
the models of ASCO solenoid valves used at VEGP.
3.
Seat Leakage.
(GJB)
After manufacture and assembly, ASCO subjects
)
each NP series valve to a factory acceptance test that evaluates the valve's suitability for shipment.
As part of this factory acceptance test, ASCO verifies the valve's operability and seat integrity.
To pass this test, valves with resilient seats must have no detectable seat
) )
I' leakage.
These manufacturing tolerances set by ASCO, y
however, are not related to leakage rates that would affect valve performance.
(GJB, GB)
ASCO's installation and maintenance
)
instructions for the four types of ASCO solenoid valves used in safety-related applications at VEGP state that excessive leakage warrants inspection of the valve.
At VEGP excessive leakage in the ASCO solenoid valves would
)
be monitored through operation of and periodic testing of the associated process valve or damper.
If during normal j
operation or inservice testing the process valve or damper fails to cycle or cycles sluggishly, then the solenoid valve would be checked.
(GJB)
In Report No. AQR-67602/REV.
O, entitled
)
" Analysis of Franklin Research Center Qualification Testing of ASCO Catalog NP-1 Valves for the Nuclear Regulatory Commission" and issued on September 26, 1983,
)
ASCO states with respect to seat leakage in its solenoid valves:
ASCO has never considered seat leakage of any
)
Catalog NP-1 valve to be critical-to the performance of a typical valve safety function unless the leakage reaches the point that it significantly-affects the status of the valve cylinder port pressure.
Since its initial qualification test program, ASCO has maintained
)
the definition of acceptability of Catalog NP-1 valves to be that the valve is considered to be
) )-
i I
performing satisfactorily as long as the cylinder port pressure does not deviate by more than 10*s I
of the applied pressure at the valve inlet port.
ASCO then calculated for several models of solenoid valves the minimum _ seat leakage needed for the cylinder port
)
pressure to reach ASCO's defined threshold of unacceptability when the supply pressure was at the catalog listed maximum.
The results of those calculations
)
for those valves representative of or similar to the models of ASCO solenoid valves used at VEGP were:

206-380-3RF 452 SCFH NP 8320A184E 151 NP 831665E 4,400 NP 8321A5E 805 NP 831666E 4,025
)
(GJB)
The amount of seat leakage that would affect an ASCO solenoid valve's ability to perform its safety related function at VEGP, which is to vent the
)
air-operator of the associated process valve or damper, would differ somewhat from the values calculated by ASCO and would depend upon several factors, including the
)
design of the system in which that valve is used.
Bechtel has therefore undertaken an analysis of maximum tolerable leakage rates for the model NP 8316, NP 8320, and NP 8321
)
ASCO solenoid valves used at VEGP.
For seat leakage to preclude an ASCO solenoid valve from performing its
> )
?
safety-related function at VEGP, the leakage would have to
)
be from the instrument air system supply line across the seat in the solenoid valve into the air operator of the process valve or damper.
Also, the quantity of instrument air leaked across the solenoid valve seat would have to be
)
sufficient to exceed the capacity of the vent port to carry it away and to cause the air operator to actuate, j
thereby preventing the air-operated valve or damper from attaining its safety-related position.
Otherwise, the process valve or damper would change-to its safety-related j
position when the solenoid valve was de-energized.
(GJB)
The amount of tolerable seat leakage for a particular ASCO solenoid valve at VEGP will depend upon several factors, including the size of the vent port in
)
the solenoid valve, the resistance to air flow in the instrument piping between the vent port and the actuator pressure chamber in the air operator, and the residual
)
pressure in the actuator pressure chamber.
In performing its analysis, Bechtel defined allowable leakage to be the maximum amount of leakage of instrument air past the solenoid valve seat and into the actuator pressure chamber that can be effectively carried away by the vent passage when the residual pressure in the actuator pressure chamber has decreased to a value that allows the air-operated valve or damper to shift to its
) \\
)
i J
I-safety-related position.
Table 10.5-2 identifies the
)
allowable' leakage rate for those model NP 8320 and NP 8321 ASCO solenoid valves used to perform safety-related functions in the containment and MSIV areas, except for
)
the recently added model NP 8321 valves on the feedwater control valves.
These valves were chosen for examination because they envelope all of the safety-related model NP 8320 and NP 8321 ASCO solenoid valves located in
)
potentially harsh environments and represent all of the different configurations of ASCO solenoid valves and
)
process valves or dampers used at VEGP.
While the
' allowable seat leakage for an ASCO solenoid valve at VEGP is dependent upon the particular valve model and its configuration with the air operator of the associated
)
process valve or damper, the allowable leakage rates identified in Table 10.5-2 are representative of the allowable leakage rates for the other model NP 8320 and NP
)
8321 solenoid valves used at VEGP.
(GJB)
The seat leakages provided in Table 10.5-2 represent a conservative assessment of acceptable seat leakages for the NP 8320 and NP 8321 valves evaluated on a case-by-case basis.
In order to determine acceptable leakages, the actual configurations of the solenoid valve, process valve, and the actuator were examined to determine the pressure at which the actuator would begin operating l l L
p
[
)
I the process valve.
Once this pressure was determined, it was reduced by a factor of two to include a 100% safety factor.
From this reduced allowable pressure, a corresponding leakage rate was calculated, and these
)
results were tabulated in Table 10.5-2.
-(GJB)
The allowable seat leakaoe for any of the NP 8316 valves used at VEGP would greatly exceed that of any
)
of the NP 8320 or NP 8321 valves shown on Table 10.5-2.
One of the most important factors in determining the allowable leakage rate for an ASCO solenoid valve is the
)-
exhaust port flow coefficient.
A review of the flow coefficients for the NP 8316 family of valves (which are provided in ASCO catalog NP-1, attached hereto as Exhibit F) shows that the exhaust port flow coefficient y
for those valves is at least 3.5.
The exhaust ports of the NP 8321 valves have a flow coefficient of 1.2, or approximately one third of the minimum flow coefficient for the NP 8316 valves.
The capacity of the exhaust port to vent seat leakage, and thus the allowable seat leakage, is directly dependent on the flow coefficient.
The
)
allowable seat leakage for the NP 8316 solenoid valves used at VEGP would, by inspection, be roughly three (or more) times greater than that of the NP 8321 valve, which I
was determined to be approximately 1000 SCFH.
Therefore, the allowable seat leakage for the NP 8316 valves would be at least 3000 SCFH.

I 1
f D.
Requiced Post Accident Operating Time.
I (SJC, HJQ)
One of the issues raised'by the Board concerned the basis for statements made by the Applicants concerning the length of time that the ASCO
[
solenoid valves'would have to operate at VEGP following a design basis event.
For all safety-related equipment, the intent of the VEGP equipment qualification program
)
is to demonstrate operability for a period of one year following a design basis event.
The one year period of post accident operability specified by Bechtel for all
')
safety-related equipment, however, greatly exceeds the interval for which safety-related ASCO solenoid valves at VEGP would actually have to remain operable following
)
the initiation of a design basis accident.
The safety function. performed by all of the ASCO solenoid valves used at VEGP is to de-energize, thereby venting the air j.
operator of the associated process valve or damper.
Once de-energized, the ASCO solenoid valves are not required to shift position again in response to any accident conditions.
Those ASCO solenoid valves that are de-energized due to automatic safety signals will complete their safety-related function within seconds.
The other ASCO solenoid valves would be de-energized by
)
remote manual plant operator action, which would occur within thirty minutes after sufficient alarm or other indication of the occurrence of the initiating
) )
)
event or in response to plant emergency operating
)
procedures.
Thus the de-energization of the ASCO solenoid valves would be complete within a few seconds to hours after the initiation of the design basis event.
)
II.
Environmental Qualification Testing Performed on the ASCO Solenoid Valves Used at VEGP.
(WVC, HJQ)
Environmental qualification testing has been performed upon the four models of ASCO solenoid valves employed in safety-related applications at VEGP in two separate generic qualification testing programs.
The
)
most recent environmental qualification program was carried out jointly by ASCO and Westinghouse in the early 1980's.
A few years earlier, Isomedix, Inc. had conducted
)
environmental qualification testing on the solenoid valves on behalf of ASCO.
Both of these testing programs established certain generic extreme environmental conditions for which the ASCO solenoid valves were environmentally qualified.
Those conditions, which were not plant specific, have been compared by Bechtel to the
)
conditions that the valves might encounter at VEGP to assure that the valves are environmentally qualified for use in safety-related applications at VEGP.
)
A.
The Joint Westinghouse and ASCO Environmental Qualification Testing Program.
(WVC, HJQ)
In 1980 and 1981, Westinghouse and ASCO jointly conducted an environmental qualification testing l
l )
7
)
program for various ASCO solenoid valves.
Test Report No.
AQR-67368/Rev.
1, issued on August 19, 1983, documents the results of that testing program.
The objective of the qualification testing program was to demonstrate that the
)
ASCO solenoid valves met or exceeded their safety related performance requirements while subjected to simulated normal and accident environments.
The conditions to which
)
the valves were tested in the joint Westinghouse /ASCO qualification testing program were generic conditions designed to establish a qualified life of 8 years and a y

to be able to operate after such an accident, but then encountered performance problems prior to the completion
)
of the full 30 day HELB test period.
In the HELB environmental testing, a period of 3.65 days at 265'F following the second transient simulated one year of actual post-accident service.
The model Np 8316 valve would not actuate at the minimum DC voltage (90 VDC) when energized thirteen days into the test.
When the voltage was increased to 125 VDC, the valve actuated and continued to require at least 110 VDC to actuate for the remainder of the thirty day test period.
(WVC, HJQ)
The ASCO specification for this valve is a nominal voltage of 125 VDC with an operating range of 90 VDC-to 140 VDC.
The 90 VDC is the worst case for the h
solenoid valve because it results in the least magnetic field being developed by the solenoid coil.
That magnetic field shif ts the solenoid c' ore, which in turn operates the valve.
The 90 VDC minimum is a Westinghouse generic requirement and is based on the scenario that the battery voltage available to the valve during and after an accident can be as low as 90 VDC.
(WVC, HJQ)
Later inspection of the valve revealed that the increase in the voltage needed to activate the I
)
valve had resulted from moisture and chemical spray
)
entering the valve solenoid enclosure and over time reducing the coil insulation resistance.
This moisture entered the solenoid housing through the conduit nipple
)
opening through which the electrical leads providing electric power to the solenoid pass.
In the test that opening was not required to be leak tight and thus was not
)
hermetically sealed.
The seal for the conduit opening is not part of the valve, and ASCO does not supply such seals with the solenoid valves.
)
(WVC, HJQ)
One of the issues raised by the Board concerned whether the unsealed solenoid housing represented a quality control deficiency that might g
endanger safe operation of VEGP.
As noted above, ASCO does not supply conduit nipple seals with its solenoid valves, and the moisture entered the solenoid housing as a result of the test setup.
Since the moisture problem originated from a test setup deficiency rather than from the model NP 8316 valve itself, that problem does not evidence a potential quality control deficiency with ASCO
)
(SJC, WVC, HJQ)
More importantly, if the moisture problem encountered with the NP 8316 valve tested in the Westinghouse /ASCO testing program were to occur with any ASCO solenoid valve used at VEGP, it could not a..fect h
1
! )
h that valve's ability to perform its safety-related
)
function, which is to vent the air operator of tne associated air-operated process valve or damper.
The intrusion of moisture into the solenoid housing of the NP 8316 valve resulted in a reduction'of the ability of the coil to shift the solenoid. core, which caused the valve to fail to operate when energized until the voltage applied to the. solenoid was increased to 125 VDC.
The design of the solenoid housing is such that the intrusion of moisture into the housing does not affect the ability
)
of the solenoid core to shift into its de-energized position..The solenoid core, the valve seats, and the other moving parts of the valve are housed in the body of the valve, which is physically separated from the solenoid housing.
Because of the physical separation of these portions of the valve, intrusion of moisture into the
)
solenoid housing cannot prevent the solenoid valve from attaining its safety-related position, which is the de-energized position for all the ASCO solenoid valves used in safety-related applications at VEGP, Because the ASCO solenoid valves utilized at VEGP perform their safety-related function when the coil is de-energized, a
i valve's inability to shift position when energized 1.o the minimum DC voltage specified, as occurred with the model NP 8316 valve in the joint Westinghouse /ASCO testing t-

The other model NP 8316 valve with ethylene propylene elastomers tested performed

successfully before, during, and after the HELB environmental testing. -Upon disassembly subsequent to the full 30 day HELB testing period and the final operational check, the diaphragm of the valve was found to be stuck to

the valve body, which caused a tear in the diaphragm.
'This sticking of the diaphragm does not represent a test failure because it occurred after successful completion of

- Moreover, the thirty day testing period to which the valves were j-subjected in the HELB testing simulates approximately eight years of service after a design basis event, which provides a considerable margin over the one year period

that Westinghouse generically specifies that the valves be operational following a design basis event.
(WVC, HJQ)
In the HELB environmental testing, the model NP 8321 valve that was tested, which had resilient j-seats made of viton elastomers, would not shift to its de-energized position on the twelfth day of the HELB test period.
This failure occurred well after that portion of the test period that simulated the period of time that the.
model NP 8321 valve would be required to operate at VEGP

The twelve-day period
).
that the model NP 8321 valve continued to operate after exposure to simulated accident conditions represents in
-excess of a year of post-accident operation at VEGP.
)
(WVC, HJQ)
Due to the f ailure of the model NP 8321 valve to complete successfully the full 30 day HELB environmental-testing, ASCO does not consider it to be qualified to the generic environmental extremes profiled on Figure 10.5-2.
Instead, it relies upon an earlier qualification testing program conducted by Isomedix, Inc.
y on behalf of ASCO to establish the generic environmental qualification of the model NP 8321 valve.
Because the portion of the HELB environmental testing completed by the
)
NP 8321 valve tested in the Westinghouse /ASCO program represents in excess of one year of post accident operation at VEGP, those test results do pro *.ide a basis for concluding that the NP 8321 valve is qualified for use at VEGP.

For model NP 8321 solenoid valves with viton elastomers, ASCO further restricts their

qualification to applications where the valves will not be b

(WVC, HJQ)
The Isomedix testing program was conducted in accordance with the test outline contained in ASCO Qualification Specification AQS-21678 Revision B, which was based upon IEEE 323-1974, IEEE 382-1972, IEEE 344-1975, and IEEE 382/ ANSI N278.2.1 (Draft 3, Rev. 1 June 7
1977)
" Draft American National Standard for the Qualification of Safety Related Valve Actuators."
The Qualification program was designed to demonstrate that the valves had a qualified life of at least four years and would operate for at least one year following a design

basis event.
l l
)
(WVC, HJQ)
In this testing program, Isomedix, Inc.
thermally aged the test valves at a temperature of 268'F for twelve days to simulate a design life of four years.
During that thermal aging, the valves were continuously
)
energized except for five minutes once every six hours when they were cycled by being de-energized.
The valves were then radiation aged and wear aged.
Next, the valves
)-
underwent seismic simulation, vibration endurance testing, and exposure to an additional 150 megarads of gamma radiation to simulate the radiation that would be
)
experienced under accident conditions.
Finally, Isomedix exposed the valves to simulated LOCA conditions.
Those conditions, which are profiled in Figure 10.5-3, included
).
a peak temperature of 346*F and peak pressure of 110 psig that were imposed for approximately three hours.
(WVC, HJQ)
The model Np 8316, Np 8320, and 206-381-6F valves performed satisfactorily.
The model Np 8321 valve initially utilized by Isomedix in the test program developed excessive seat leakage (50 SCFH) both in the energized and de-energized states after seven days of the thermal aging portion of the test procedure.
At the end of that portion of the test, the test valve was examined and the cause of the excessive leakage was determined to be dirt in the valve originating from an iron pipe attached to the cylinder port and an additional length l )
).
used to simulate an accumulator.
Because the cause of the performance problems with the model NP 8321 valve being
)
tested was contaminants introduced from an external source as a result of a deficiency in the test procedure, ASCO
)
substituted another model NP 8321 valve in the test.

After approximately 60 hours6.944444e-4 days <br />0.0167 hours <br />9.920635e-5 weeks <br />2.283e-5 months <br /> of this thermal aging, the valve

started leaking in the energized state.
The leakage was 40 SCFH at 200 psig, 17 SCFH at 125 psig, and 3 SCFH at 10 psig.
The valve shifted properly and had no leakage in the de-energized state.
(WVC, HJQ)
Isomedix determined that the seat leakage resulted from the softening and resultant degradation of valve elastomer material caused by the higher temperature
)-
of 295*F used in the thermal aging.
Normal 140*F ambient temperature would not cause noticeable softening of this material.
As the valve performed its safety function, the
)
thermal aging continued and the other tests were conducted on this valve in the same manner as on the other test valves.
As a result of the seat leakage encountered during thermal aging, ASCO reduced the specified maximum operating pressure differential at which the model NP 8321 l

)
valve can operate from 200 psig to 150.psig.
This change

resulted in a 25% load reduction on the resilient seat.
(WVC, HJQ)
At the end of the LOCA simulation, the coil of the model NP 8321 valve had an insulation
)
resistance of less than one megohm, so a coil dielectric test was not performed.
During the LOCA phase, the solenoid enclosure was wired through a flexible electrical j_
conduit rated for 120*F.
During the 30-day LOCA simulation, the plastic covering on this conduit broke down, allowing the spray solution to enter the solenoid
)
and degrade the coil insulation, resulting in current leakage to ground.
Upon disassembly, the valve solenoid enclosure was found to be full of spray solution.
After the coil was dried out for 7 days at room temperature, the
)
insulation resistance was found to be 14 megohms and the coil dielectric test was entirely satisfactory.
Since the
)-
coil had satisfactory insulation resistance and passed the dielectric test prior to the LOCA test, Isomedix concluded that the coil would have been satisfactory except for the adverse effect of the spray solution, which condition
)
resulted from the use of an unqualified conduit and not from any problem with the model NP 8321 valve itself.
As described above, moisture entering the solenoid housing of

The Franklin Research Center Testing Program j
(WVC, HJQ)
In 1981 Franklin Research Center
(" Franklin") initiated a testing _ program on ASCO solenoid valves under a contract from the NRC.
The valves tested
.by Franklin included two model NP 8316 valves, one model NP 8320, and one model NP 8321, all with ethylene propylene elastomers.
Franklin also tested a model
)
206-381-6F valve, which is the same as the model 206-381-6RF valves used at VEGP'except that it has metallic rather than resilient seats.
Following
)'
functional tests, Franklin artificially aged one-of the model NP 8316 valves and the model NP 8320, NP 8321, and 206-381-6F valves to simulate a four-year life at 140*F.
)'
Those valves were irradiated to a total integrated dose of 50 megarads and then exposed to a temperature of 268'F for
- )-
)
approximately fifteen days.
The valves were cycled 2000
)
times over the thermal aging period while at that elevated temperature.
(WVC, HJQ)
The_ artificial thermal aging process
)
employed by Franklin imposed conditions on the elastomeric parts of the valves that were far in excess of normal conditions or the standards for accelerated aging
)
established by IEEE 323-1974.
In its report of its test results, Franklin itself acknowledged that its artificial aging process was overly severe, stating:
)
Cyclical aging during thermal aging presents a different type of overconservatism.
IEEE Std 382-1980 requires that 10% of the operational cycles be conducted during thermal aging at the thermal aging temperature.
However, when dealing with organic seats and seals, it should be determined if the cycling of
)
the valves at the accelerated aging temperature may introduce stresses on the material that might not exist in normal operation.
The EpDM discs and seats common to these valves raise this possibility.
Since a previous test (the Isomedix test] did indicate softening of the EpDM during thermal aging at 295'F
)
(146*C), the aging at 268'F (131*C) may have produced softening and the cycling at this temperature may have produced stresses not present in normal operation.
NUREG/CR-3424 at 2-64.
In a separate Appendix to the
)
report describing the thermal aging analysis, one of the report's authors concludes that "it was inappropriate to cycle a solenoid valve containing elastomeric seals at
)
ambient temperatures in excess of normal rated ambient

temperatures (140*/60*C and 180*F/82*C for the valves
).
discussed in this report)."
NUREG/CR-3424 at C-1.
(WVC, HJQ)
Following this artificial aging, the model NP 8321 valve was removed from the test program because of
)_
what Franklin Research Center characterized as " excessive" seat leakage.
Franklin's ability to measure seat leakage accurately was limited by the nature of its test
)
apparatus.
When testing a valve for seat leakage, Franklin attached a tube to the exhaust port of the valve and immersed the other end of the tube in water with a
)
water-filled 1000 ml graduated cylinder inverted over it to trap any bubbles emanating from it.
Franklin reported the leakage rate that it encountered with the model
)
NP 8321 valve to be "more than" 60 liters per minute at 150 psig following the accelerated thermal aging.
(GJB)
As noted earlier in this testimony, ASCO has
)
calculated the minimum seat leakage that would cause the cylinder port' pressure to reach ASCO's defined threshold of unacceptability to be 805 SCFH (380 liters per minute) for the model NP 8321 valve tested by Franklin.
)
Moreover, for the specific valve configurations including NP 8321 valves located in a harsh environment at VEGP, Bechtel has determined the maximum allowable seat leakage
)
to be 555 SCFH (maximum allowable leakage for one of two NP 8321 valves used in series with the second
) )
1 I
NP 8321 valve assumed to fail to shift from the energized

to the de-energized position).
(WVC, HJQ)
The Board has questioned whether the amount of leakage shown by the model NP 8321 valve tested
)
by. Franklin was dependent upon the length of time that the valve was left in the test program.
While the seat leakage exhibited by that valve could have increased had
)
it been subjected to the remaining aspects of the testing.
program, any additional test results would have had little meaning in light of the overly severe artificial aging to
)
which the model NP 8321 valve was subjected by Franklin.
The excessive severity of that artificial aging process
.was a primary cause of the breakdown of the valve's
)
elastomeric material that produced the gross seat leakage found by Franklin.
(WVC, HJQ)
The other model NP 8316 valve had been
)
naturally aged by ASCO at 140*F for three years, without any radiation exposure.
That valve had been cycled 2000 times at room temperature.
)
(WVC, HJQ)
All the valves then underwent pressurization testing, vibration aging, resonance search, seismic testing, design basis event radiation exposure, and a simulated composite LOCA and MSLB exposure.
The composite LOCA/MSLB exposure included steam, chemical spray, and high humidity conditions.
Two transients were
) *
)
)
simulated, each with a targeted peak temperature of 420*F f
and pressure of 68 psig.
Thermocouple data from the test chamber, however, indicated that certain areas in the chamber' experienced temperatures higher than the intended
)
test conditions.
(WVC, HJQ)
The ASCO model 206-381-6F valve-performed satisfactorily through all of the tests.
.The model
)-
_NP 8320 valve tested by Franklin Research Center functioned throughout the tests.
In the functional testing following the completion of the LOCA/MSLB
)
simulation, however, the model NP 8320 valve did experience what Franklin Research Center described as
" severe" seat leakage.
No seat leakage had been observed
)
with'the model NP 8320 valve prior to that point.
At 150 psig, the seat leakage exceeded 100 cubic feet per hour.
That seat leakage did not prevent the valve from being
).
cycled.
As with the model MP 8321 valve, the excessively severe artificial aging process used by Franklin calls into question the meaningfulness of the seat leakage found
)
by Franklin with the model NP 8320 valve.
(GJB)
Moreover, the seat leakage encountered by Franklin with the NP 8320 valve exceeded the allowable seat leakage conservatively calculated by Bechtel for the NP 8320 valves used at VEGP only where the NP 8320 valve is used in series with another NP 8320 valve and that second valve is assumr.d to fail to shift from the
)
energized to the de-energized position. )

)
(WVC, NJQ)
The model NP 8316 valve that had been
)'
artificially aged could not be cycled properly between the first and second transients of the composite LOCA/MSLB simulation because the air supply could not be maintained
)
at sufficient pressure and volume due to excessive seat leakage and rate of cycling.
The air supply to the valve was oil-free bottled air with the air pressure kept at 175
')
psig, which was the maximum value specified by ASCO for the model NP 8316 valve.
Prior to the start of the second transient, Franklin was able to supply sufficient air
)
pressure and volume to cycle the valve, and it continued to function until four days elapsed time in the LOCA/MSLB simulation.
At that time, the test valve cycled to the
)
open position (i.e., process cylinder pressurized) when energized but did not transfer back when de-energized.
Franklin had to shut off the air supply to the valve to
)
avoid large losses of bottled air and to prevent this bottled air from pressurizing the test vessel.
The valve was briefly pressurized with air during subsequent scheduled cycling tests to attempt operation, but the
)
attempts were unsuccessful.
Franklin reported that "at the conclusion of the LOCA/MSLB exposure, leakage rates were greater than 100 [SCFH]" for the valve.
The causes
)
of the failure of this valve are discussed in detail in a later portion of this testimony.

Franklin identified the failure mechanism for that valve to have been gross I
failure of the pressure and exhaust diaphragms due to embrittlement and cracking.
(WVC, HJQ)
In November 1983, Franklin issued a report
)
concerning its test results, entitled " Test program and Failure Analysis of Class IE Solenoid Valves."
After reviewing those results, the NRC
)~
Staff in December 1983 revoked those portions of a Safety Evaluation Report that it had previously issued to Westinghouse that related to the environmental j
qualification of the ASCO model Np 8316 valve.
In April 1984, the NRC Staff issued IE Information Notice No. 84-23, which reported its initial assessment of the Franklin test results.
p l
(WVC, HJQ)
In IE Information Notice No. 84

valves in the Franklin tests, concluding that those test j
results were inconclusive due to the severe i
preconditioning to which those valves were exposed.

program.
That model ASCO solenoid valve, the NRC Staff concluded, was acceptable for use only in applications where the environmental conditions to which it might be J
exposed were enveloped by the conditions to which that model valve had been tested earlier by Isomedix, Inc. on behalf of ASCO.
The NRC Staff reiterated its conclusions concerning the model NP 8316 valve in IE Information

Notice No. 85-08 issued on January 30, 1985.
After stating that the NRC Staff considered all ASCO NP series solenoid valves with ethylene propylene elastomers other

than the model NP 8316 to be qualified to the levels reported in the joint Westinghouse /ASCO testing program, that notice stated:

D.
The Results of the Franklin Testing Program Do Not Call Into Question the Environmental Qualification of the ASCO Solenoid Valves for Use
)
at VEGP.
(WVC, HJQ)
Westinghouse and ASCO have each evaluated the results obtained by Franklin.
Both Westinghouse and )
)f ASCO concluded that because of anomalies in the test
)
procedure used by Franklin and the more severe environmental conditions to which it tested the valves, the test results obtained by Franklin do not call into question the validity of the test.results found in the joint Westinghouse /ASCO qualification testing program.
l.
The Model NP 8316 Valves
)
~(WVC, HJQ) ~With respect to the test valves that Franklin artificially aged, including the artificially aged model NP 8316 valve, the differences-in their
)
performance'in the Franklin tests and in the prior t
Westinghouse /ASCO testing program can be attributed to differences in test procedure, specifically the thermal
)
aging and radiation aging procedures used.
Franklin irradiated the test valves initially with a significant gamma dose of 50 megarads and then during the accelerated thermal aging cycled the valves 2000 times at a
)
temperature of 268'F.
Fifty (50) megarads is more severe than the four year normal radiation dose, which is about 2
)
.megarads for Westinghouse generic environments and for VEGP is 0.2 megarads.
Further, cycling at high aging temperatures is not a normal condition and presents a very severe condition for the elastomeric parts of the valves.
)
For those reasons, the more severe degradation of the artificially aged valves in the Franklin test is understandable and to be expected. )
)
(WVC, NJQ)
Franklin's analysis of the artificially
)-
aged NP 8316 valve subsequent to the testing indicates that in' addition to the adverse effects of the overly severe artificial aging process, the failure of the
)
artificially aged model NP 8316 valve was due in part to contaminants found during inspection of the valve.
Franklin identified three possible failure mechanisms for
)
the artificially aged NP 8316 valve.
First, coil resistance measuremcnts indicated that the coil was open.
Second, Franklin surmised that the cause of the valve's
)
failure to operate after 4 days elapsed time into the second transient of the LOCA/MSLB simulation was solidification of an organic lubricant or grease on the
)'
solenoid core assembly, which may have caused the core assembly to bind when inserted into the solenoid base subassembly, and a break in the core spring, which
)
prevented that spring from freeing the core assembly upon de-energization of the valve.
Traces of chlorine, which is extremely corrosive to stainless steel, were found at the break point on the spring, and the chlorine apparently
)
contributed to the breaking of the spring.
The third failure mechanism identified by Franklin was extensive degradation of the pressure and exhaust diaphragm
)-
assemblies.
(WVC, HJQ)
ASCO attributes the open solenoid coil reflected by Franklin's coil resistance measurements to
_45
)
).
-the entry of water into the solenoid housing.
As
)
described above, the entry of water into the solenoid housing of an ASCO solenoid valve at VEGP would not affect its ability to perform its safety-related function.
)
(WVC, '4JQ)
The solidified organic lubricant found by Franklin on the solenoid core assembly and the chlorine present on the cracked core spring strongly suggest that
)
Franklin's test procedure permitted the introduction of contaminants into the valve.
ASCO applies the lubricants used in model NP 8316 valves in relatively small
)
quantities that could not account for the amount of solidified lubricant that was found by Franklin.
The presence of solidified core lubricant has never been
)-
detected in any ASCO NP series solenoid valve either in the field or in a qualification test program.
ASCO carefully controls the materials and manufacturing
)
procedures used in the fabrication of the NP series solenoid valves to eliminate the possibility of halogen contamination and has not detected failure of a core spring similar to that observed by Franklin in any NP
)
series valve either in the field or in a qualification testing program.
Finally, ASCO has never observed the softening and flowing of the elastomeric material of the
)
diaphragm found by Franklin with respect to the artificially aged NP 8316 valve (shown in Figure 17 of
) )
NUREG/CR-3424) on any model NP 8316 valve either in the
)
field or in any qualification test.
We conclude, therefore, that the observed failure modes and the inability of the valve to operate beyond four days are
)
attributable to the overly severe artificial aging process utilized by Franklin and the apparent introduction of contaminants into the valve during the testing.
)
(WVC, HJQ)
The failure of the naturally aged model NP 8316 valve in the Franklin program can also be attributed to differences in the testing procedures used
)
in the joint Westinghouse /ASCO testing program and the Franklin tests.
The targeted peak temperatures during the LOCA/ MSLB simulations in both testing programs was 420*F.
The actual temperature peaks reached in the
)
Westinghouse /ASCO tests for the two transients were 440*F and 450*F.
For the two transients in the Franklin LOCA/MSLB simulation, the temperature peaked at 450*F and
)
466*F.
More importantly, thermocouple data from the test chamber in the Franklin test indicate that the surface temperature of the naturally aged model NP 8316 valve,
)
which would lag behind the test chamber temperature, reached 410*F, substantially higher than the 350*F to 360*F temperatures reached by any other valve in the test chamber that had a thermocouple either inside its coil enclosure or taped to its body, including the other model Y
47
)
D NP 8316 valve.
The substantial difference in the p
temperatures reached by the two NP 8316 valves indicates that the mass flow rate and velocity of steam at each valve was different and that the valves in the test were p
not exposed to uniform conditions.
When the valve reaches a temperature of 410*F, the elastomers in the valve are well above their damage threshold and would degrade p
rapidly.
(WVC)
Based upon the NRC Staff's evaluation of the Franklin test results, however, Westinghouse has modified p
the generic composite LOCA/MSLB temperature and pressure profile to which it considers the model NP 8316 valve to be qualified by reducing the peak temperature during each transient to 400*F.
A thermal lag analysis performed by p
Westinghouse for the model NP 8316 valve, which analysis determines the temperature reached by the valve itself, has shown that upon exposure to the conditions shown in y
the modified Westinghouse LOCA/MSLB profile, the maximum temperature that would be reached by that valve under LOCA/MSLB conditions would be 345'F.
That temperature is g
below the maximum temperature of 346*F that was reached by the model NP 8316 valve in the qualification testing program performed by Isomedix, Inc.
As the NRC Staff g
concluded in IE Information Notice Nos. 84-23 and 85-08, the results of the earlier Isomedix testing program have P D
)
not been called into question by the valve failures experienced in the Franklin tests under significantly more severe environmental conditions.
2.
The Model NP 8320 Valves.
)
(WVC, HJQ)
The model NP 8320 valve tested by Franklin was artificially aged.
While the valve could be operated throughout the test sequence, in the functional testing
)
after the conclusion of the LOCA/MSLB simulation it had seat leakage " greater than 100 [SCFH)" at 150 psig.
The model NP 8320 valve had not exhibited any seat leakage
)
prior to that point, including during the LOCA/MSLB simulation.
As discussed above and as concluded by the NRC Staff in IE Information Notice Nos. 84-23 and 85-08,
)
the results obtained by Franklin do not call into question the qualification of the model NP 8320 valve to the conditions to which it was tested in the Westinghouse /
)
ASCO testing program because of the excessively severe artificial aging process used by Franklin, which process imposed stresses on the artifically aged valves,
)
particularly on their elastomeric parts, to which those valves would not be subject in normal operation.
3.
The Model NP 8321 Valves.
(WVC, HJQ)
The seat leakage encountered by the
)
Franklin with the artifically aged model NP 8321 valve that it tested does not call into question the environmental qualification of that model valve for use at VEGP.
As
)
discussed above, the excessive severity of the artificial aging process employed by Franklin, which Franklin itself
)
)
acknowledged was inappropriate, was a primary cause of the
)
NP 8321 valve's performance in the Franklin tests.
Because Franklin's test conditions were not representative of conditions the NP 8321 valve might experience in a
)
nuclear facility such as VEGP, Franklin's test results have no applicability to and cast no doubt upon the environmental qualification of the model NP 3321 valve for use at VEGP.
)
E.
The ASCO Solenoid Valves Used in Safety-Related Applications at VEGP Are Environmentally Qualified for Use In the Environmental Conditions to Which They Might Be Exposed at VEGP.
)
1.
The Environmental Conditions at VEGP.
(a)
Inside Containment.
(SJC)
The maximum environmental extremes to which the
)
ASCO solenoid valves located inside containment might be subject under accident conditions at VEGP are (a) a peak temperature of 400*F, (b) pressure of 50 psig,
)
(c) radiation of 200 megarads total integrated dose, and (d) a chemical spray of 2000 ppm boron buffered with sodium hydroxide to a short term pH (less than 100
)
minutes) of 10.5 and a long term pH (more than 100 minutes from the beginning of the LOCA) of 8.5.
(SJC) The adverse temperature conditions to which ASCO
)
solenoid valves located inside containment at VEGP must be qualified are profiled in Figure 10.5-6.
That profile k )
).'
represents a composite of the conditions resulting from a
)
Because it is a, composite of several different design basis events, that profile reflects conditions that are significantly worse than the
)
conditions that would result from any single design basis event.
Inherent in this profile are the following margins
.(difference between specified qualification value and
)
calculated value):
for peak temperature, in excess of 40*F; for peak pressure, in excess of 15%; and for radiation, in excess of 20%.
)
(b)
Outside Containment (Except the MSIV Areas).
(SJC)
Most of the rooms outside containment are subject to mild environmental conditions even following y
postulated design basis accidents.
Those rooms that do experience harsh environments experience conditions significantly less severe than those existing inside containment.
For example, the harshest environment that
)
would be experienced under accident conditions by ASCO solenoid valves outside containment, except in the main steam isolation valve ("MSIV") area, is a peak temperature of.250*F, a peak pressure of 3.5 psig, and radiation of 100 megarads total integrated dose.
(c)
MSIV Areas.
)
(SJC)
The most severe temperature and pressure conditions to which safety-related ASCO solenoid valves located outside )
J containment might be exposed would occur in the MSIV i-areas.
The conditions to which Bechtel has requirt.d
)
safety-related equipment located in the MSIV areas outside containment to be qualified are a peak temperature of 320*F, a peak pressure of 15 psig, and radiation of 50 megarads total integrated dose.
Figure 10.5-7 profiles the extreme temperatures to which Bechtel required
)
safety-related equipment in the MSIV areas outside containment to be qualified.
Bechtel has recently determined, however, that under certain accident
)
conditions the peak temperature in the MSIV areas outside containment could exceed 320*F.
(SJC)
In late December 1985, analyses performed for j
the MSIV areas at VEGP indicated that the temperature conditions s,hown on Figure 10.5-7 could be exceeded under certain conditions in the MSIV areas in the event of a steam line break outside of containment that resulted in a
)
steam generator tube bundle being uncovered, causing super'eated steam to be released.
Prior analyses did not h
j consider that superheated steam could be discharged from the steam generator following a steam line rupture.
On December 7, 1934, the NRC issued IE Information Notice 84-90, " Main, Steam Line Break Effect on Environmental y
Qualification of Equipment" to notify pressurized water reactor plants of this issue.
Resolution of the superheat
)
g
- 3
)
issue has been identified by the NRC Staff as a p
confirmatory item in tne Safety Evaluation Report issued k
for VEGP in mid 1985.
(SJC)
VEGP has participated in the Westinghouse Owners Group ("WOG") sub group addressing the issue of superheated steam mass and energy releases outside containment.
This was a generic program to assess mass and energy releases from steam line breaks outside containment.
The 23 represented plants were divided into 6 categories based on system size, number of reactor p
coolant loops, rated NSSS power, and steam line break protection system design.
The assumptions used in the mass and energy release analysis were chosen to envelope g
)
all plants in a given category.
VEGP Units 1 and 2 were grouped together with 9 other units.
(SJC)
The WOG sub group provided the Applicants with mass and energy release data on October 25, 1985.
Using p
that data, Bechtel then over a two month period calculated time dependent temperature profiles for all possible accident conditions in the MSIV areas.
In some cases, g
these temperature profiles exceeded the temperature profile of 320*F that had been determined for qualification of equipment in the MSIV areas.
g (SJC, WVC) Two models of ASCO solenoid valves, the NP 8320 and NP 8321 valves, are located in the MSIV areas P D
q
)
and would have to-function following a main steam line break.
A thermal lag analysis performed by Westinghouse demonstrates that for the worst case determined based upon the temperature profiles calculated by Bechtel using the
)'
generic mass and energy release data developed by the WOG sub group, the temperature reached by the NP 8320 and NP 8321 valves in the MSIV areas will not exceed 332*F.
)
This is well within the Isomedix test envelope of 346'E.
(SJC)
The WOG sub group generic mass and energy releases are believed to be conservative for VEGP.
}
Therefore, a VEGP specific analysis is being performed and is scheduled to be completed later this year.
A submittal to the NRC is presently scheduled for July 1986.
2.
The Model NP 8316 Valve Is Environmentally
)
Qualified for Use at VEGP.
(SJC, WVC, HJQ)
The model NP 8316 ASCO solenoid valve
)
is used in safety-related applications at VEGP both inside and outside containment.
One NP 816 valve is located in the MSIV area outside containment.
It, however, performs
)
no safety-related function for any steam line or feed line break in the MSIV area.
The model NP 8316 valve has been shown to be environmentally qualified for use at VEGP either inside or outside containment by both the Westinghouse /ASCO and Isomedix qualification testing programs as supplemented by a thermal lag analysis
) -
)
h performed by Westinghouse.
Because of the NRC Staff's f
evaluation of the Franklin test results, Westinghouse has modified the generic composite LOCA/MSLB temperature and pressure profile tc which it considers the model NP 8316 f
valve to be qualified as a result of the joint Westinghouse /ASCO testing program by reducing the peak temperature during each transient to 400*F.
The thermal
')
-lag analysis performed by Westinghouse for the model NP 8316 ASCO solenoid valve demonstrated that for the modified Westinghouse LOCA/MSLB profile with a peak
)
temperature of 400*F, the maximum temperature that would be reached by that valve under LOCA/MSLB conditions would be 345'F.
That temperature is below the maximum
)
temperature of 346*F that was reached by the model NP 8316 valve under the Isomedix testing program, which has been accepted by the NRC Staff.
(SJC, WVC, HJQ)
The temperature conditions to which
)
ASCO solenoid valves located inside containment at VEGP must be environmentally qualified are thdse conditions profiled in Figure 10.5-6.
As shown by that figure, the
)
peak temperature of 400*F (which includes a margin in excess of 40*F) would have a duration of three minutes.
The temperature conditions reflected in Figure 10.5-6 are enveloped by the conditions profiled in Westinghouse's modified generic LOCA/MSLB profile described above.
)
-5s-
Therefore, the peak temperature that would be reached by a p
model NP 8316 solenoid valve inside containment at VEGP in the event of a design basis event would not exceed the temperature reached by that valve in the Isomedix test.
3.
The Model NP 8321 Valve Is Environmentally Qualified for Use at VEGP.
(SJC, WVC, HJQ)
The model NP 8321 ASCO solenoid valve D
is used in safety-related applications at VEGP only in areas outside containment, including the MSIV areas.
The environmental qualification of the model NP 8321 valve for D
use at VEGP has been demonstrated by the qualification testing programs conducted by Isomedix and Westinghouse /
ASCO, as supplemented by a thermal lag analysis completed D
by Westinghouse.
(WVC, HJQ)
For all safety-related applications of the NP 8321 valve, the most extreme pressure and radiation conditions to which that valve might be exposed are easily enveloped by the conditions to which that model valve was tested in the Isomedix testing program.
The most extreme temperatures to which the NP 8321 valves might be exposed at VEGP would occur in the MSIV areas as a result of superheat conditions following a main steam line break.
I For those model NP 8321 valves located in the MSIV areas at VEGP, Westinghouse has performed a thermal lag analysis
> D
1
)-
using the temperature profiles generated by Bechtel from the WOG's generic mass and energy release data.
That analysis demonstrates that under the worst case conditions, the temperature of the model NP 8321 valves
)
located in the MSIV areas would not exceed 332*F, which is significantly below the 346*F temperatures to which those valves were qualified in the Isomedix tests.
That thermal
)
lag analysis for the model NP 8321 valve was performed using the same methodology used in the thermal lag analysis done for the model NP 8316 valve inside
)
containment described previously.
(WVC, HJQ)
Further evidence of the environmental qualification of the NP 8321 valve for use at VEGP was
)
provided by the joint Westinghouse /ASCO testing program.
Although the test valve representative of the model NP'8321 valve failed during the HELB environmental testing
)
in the joint ASCO/ Westinghouse qualification program, that f ailure did not occur until twelve days into the test sequence, a period which simulated in excess of a year of
)
post-accident operation at VEGP.

The NP 8320 Valve Is Environmentally Qualified for Use at VEGP.

For those model NP 8320 valves located in the MSIV areas outside containment, the thermal l

lag analysis performed by Westinghouse for model NP 8321 j
solenoid valves located in the MSIV areas establishes that the temperature of the ASCO solenoid valves in that area j
will not exceed 332*F, which is significantly less than the temperature of 346*F to which those valves were exposed for three hours in the Isomedix tests.
The model NP 8320 valve is similar in weight and has less surface
)
area than the model NP'8321 valve.
Therefore, its thermal response would be such that it would not reach a peak

temperature greater than the peak temperature of 332*F that the thermal lag analysis demonstrated might be reached by the model NP 8321 valve in the MSIV areas upon exposure to main steam line break conditions.

demonstrated by the joint Westinghouse /ASCO qualification j
testing program and the Isomedix testing program.
No model 206-381-6RF solenoid valves are used inside containment or in the MSIV areas at VEGP.
All of these valves are located inside the auxiliary building and are y
subject to a peak temperature of less than 250'F.
Therefore, ASCO solenoid valve model 206-381-6RF is j
qualified for use in its safety-related applications at VEGP.
III.
The ASCO Solenoid Valves Will Perform as Intended at VEGP.
)
(GJB, SJC)
As discussed above, the ASCO solenoid valves used in safety-related applications at VEGP are all of the normally closed design.
This means that when the ASCO solenoid valve is de-energized, the pressure chamber in the air operator of the associated process valve or damper is vented to the atmosphere and the passage of y
instrument air to the air-operated valve or damper is blocked.
Thus,-the systems in which ASCO solenoid valves are used at VEGP are designed so that for the most likely
)
failure, loss of power, the ASCO solenoid valve will assume a position that will vent the associated air-operated valve or damper, causing it to assume its safety-related position.
The same result would occur upon a loss of instrument air.
) )
\\
(GJB, SJC)
The possibility of a random failure of an
).,
.ASCO solenoid valve at VEGP that might result in the associated air-operated valve or damper not assuming its safe position cannot be eliminated completely.
For
)~
example as discussed previously, a gross leak of instrument air across the solenoid valve seat that exceeded the exhaust capacity of the valve's exhaust port j.
could prevent the ass)ciated air-operated valve or damper from. attaining its safety-related position.
As discussed below, however, VEGp systems are designed so that no j
single f.'ailure of an ASCO solenoid valve would jeopardize safe plant operation, and the environmental qualification testing performed on the ASCO solenoid valves provides p
assurance that common mode failures of those valves will not occur.
A.
The Failure of a Single ASCO Solenoid Valve Cannot Jeopardize Safe Operation of VEGP.
(SJC)
A fundamental philosophy incorporated into the design of VEGP safety-related fluid and'HVAC systems ic the ability to perform safety-related functions even with
)
the postulated occurrence of the most limiting single failure and associated consequential failures.
Consistent with this design philosophy, the applications of ASCO solenoid valves in the safety-related fluid and HVAC systems at VEGp are such that the failure of a single ASCO
) -
).
)
9 solenoid valve will not prevent the affected system from
).
performing its safety-related function.
(SJC)
At VEGP, ASCO solenoid valves are used to effect the repositioning of air-operated valves and
)
With the exception of the HVAC dampers in the diesel generator building and auxiliary feedwater pumphouse, the safety-related air-operated valves and dampers controlled by ASCO solenoid valves are designed to shut when the air-operator is vented, causing isolation or termination of a non-essential flow path.
Figures 10.5-4
)
and 10.5-5 provide schematic representations of the seven basic configurations of process valves or dampers and associated ASCO solenoid valves utilized at VEGP.
Figure
)
10.5-4 depicts containment isolation configurations, and Figure 10.5-5 depicts other isolation schemes.
(SJC)
As shown in Figure 10.5-4, the failure of any single ASCO solenoid valve, or any single air-operated valve, does not cause loss of containment isolation i
because of the independent, redundant means of isolating j
each line by air-operated valve, check valve, or motor-operated valve.
Similarly, schematics A and B in Figure 10.5-5 show configurations that ensure isolation occurs even with the postulated failure of any single ASCO solenoid valve or air-operated valve.
In schematic C of Figure 10.5-5, only one air-operated valve is available to
) )
[
isolate the flow path; however, the air-operator of that
[
valve is vented by at least two ASCO solenoid valves in series, each receiving an independent, redundant safety signal, thereby accommodating the failure of any single
[
ASCO solenoid valve without loss of isolation function.
The final configuration shown on Figure 10.5-5 depicts one air-operated process valve with a single ASCO solenoid valve.
This configuration is used in seven locations:
)
Nuclear Service Cooling Water ("NSCW") Basin A Blowdown Isolation Valve NSCW Basin B Blowdown Isolation Valve
)
Demineralized Water Supply to Reactor Make Up Water Storage Tank Isolation Valve.
Demineralized Water Supply to Condensate Storage Tank (" CST") 1 Isolation Valve.
Demineralized Water Supply to CST 2 Isolation Valve.
CST 1 to Degassifier Feedpump Suction Isolation Valve.
)*
CST 2 to Degassifier Feedpump Suction Isolation Valve.
Single failure analyses performed by Bechtel for each of these systems show that loss of the isolation function of y
any one of these valves does not adversely impact the safety of the plant.
(SJC)

The HVAC dampers and associated ASCO solenoid valves servicing the train A

diesel 'for each unit are duplicated by identical and independent dampers and ASCO solenoid valves for the train 1 8 diesel.
The single failure of any ASCO solenoid valve

or-HVAC damper will not prevent.at least one train of the emergency onsite power supply from functioning properly.
The auxiliary feedwater pumphouse houses two motor driven
)
pumps and one turbine driven pump, each in an independent pumproom.
Only the dampers servicing the turbine driven-
- pump rely on ASCO solenoid valves for repositioning.
J:
Because.each motor driven pump is designed to~ supply 100%
of the auxiliary feedwater flow necessary'for accident mitigation and safe shutdown, the failure of the ASCO
)_
solenoid valve and consequential loss of the turbine driven. pump does not adversely impact the safety of the plant.

The use of ASCO solenoid valves at VEGP to y-effect the repositioning of air-operated valves and dampers-to desired safety-related positions therefore ) -;
T.
complies with the General Design Criteria set out in 10

CFR Part 50, Appendix A.
The configurations of air-operated valves or dampers and ASCO solenoid valves at VEGP either preclude loss of function due to a single
)
failure or have been analyzed to show that the single failure does not adversely impact the safety of the plant.
Thus, the ability of the safety-related systems at
)
VEGP that include ASCO solenoid valves to perform their safety function will not be affected by any type of random failure of an ASCO solenoid valve.

B.
The Environcental Qualification Testing Performed on the ASCO Solenoid Valves Used at VEGP Establishes That Those Valves Will Not Be Subject to Common Mode Failures as a Result of Adverse Environmental Conditions

(SJC, HJQ)
In accordance with General Design Criterion 4, and as committed to by the Applicants in Sections 3.1 and 3.11 of the Final Safety Analysis Report for VEGP, safety-related structures, systems, and components used~in safety-related

(GB) Planned Maintenance and Surveillance is a program
)
that schedules equipment maintenance, calibration, and surveillance activities.
Its purpose is to maintain equipment in a condition safe for operation, minimize
)
unplanned outages due to breakdown, and provide a mechanism by which greater than anticipated degradation of safety-related equipment can be detected and remedied.
h The program is being developed using personnel experienced in the area of maintenance and surveillance of electrical, mechanical, and instrumentation and controls equipn.ent.
)
(GB) Under the program, a planned maintenance and surveillance checklist is prepared for each piece of safety-related equipment and identifies the maintenance j
and surveillance tasks to be performed.
If the task requires removing components for internal inspection, an equipment-specific procedure is referenced describing how
)
the removal and inspection is to be performed.
If the task only requires visual inspection of the outer areas of the equipment, it is described on the checklist.
The
)
content of the program is derived from the following sources:
Manufacturer / Vendor recommendations y
Lubrication requirements Calibration requirements Field verification of equipment descriptions
)
Industry experience Qualification testing results )
i
)
(GB)
The Planned Maintenance and Surveillance Program
).
requires that all safety-related ASCO solenoid valves be replaced prior to the expiration of their qualified life.
The' entire solenoid valve will be replaced at this time.
)
Once removed-from service, the solenoid valve will be inspected for degradation.
(GB) In addition to that required by the Planned
)
Maintenance and Surveillance checklists, surveillance and operability testing will be performed on safety-related process valves under the VEGP Inservice Testing Program.
}
The Inservice Testing is conducted in accordance with ASME Section XI.
Under the Inservice Testing Program, all safety-related active valves required by ASME Section XI j.
-are tested on a regular basis.
The process valve testing includes determination of leak rates for isolation valves, stroke times, fail safe verification, and position indication verification.
The ASCO solenoid valves must
)
function correctly to regulate the air flow to the air operator of the process valve for the process valve to y
pass these tests.
The information from the Inservice Testing Program will be trended so that degradation can be predicted and planned maintenance intervals can be adjusted.
)
(GB) When required, corrective maintenance will be performed to assure satisfactory equipment operability.
) )
f Such corrective maintenance will become part of an
{
equipment history file.
Proper documentation of corrective maintenance actions will highlight recurring situations in similar equipment and will provide data to h
identify component past performance trends.
Furthermore, equipment or component failures detected in other nuclear power plants will be available to VEGP through Industry j
Event Reports, IIRC IE Bulletins, Information Notices, Letters, Directives, and Manufacturers' Information Notices.
VEGP will review these reports to determine their applicability and will modify its maintenance and surveillance program accordingly.
(GB)
Because it provides a mechanism by which valve y
performance can be monitored and greater than anticipated degradation of safety-related equipment can be detected and remedied, the Planned Maintenance and Surveillance Program provides additional assurance that the ASCO solenoid valves used in safety-related applications at VEGP will perform as intended.
