.i" 3.0 TEST SPECIMEN DESCRIPTION l

The test specimens were two flex wedge gate valves equipped with limitorque actuators.

1 The 14-inch specimen was a 600#-class Powell Valve, equipped with an SB-3 actuator. The U

valve was furnished by Grand Gulf Nuclear Plant and came equipped with a Teledyne Smartstem. Entergy Operations informed Wyle that the disc angle was 5*. This was used for

{

all calculations.--The " Max " pressure value for testing considerations-was-1080 psig.

v The 3-inch specimen was a 900#-class Velan Valve, equipped with an SMB-00 actuator. The g

valve was fumished by River Bend Nuclear Pbnt. There was no stem thrust or torque I

instrumentation installed on the valve, when recei. d. Wyle measured the disc angle to be 3.5*.

ny This value was confirmed by Entergy Operations fNm Velan drawings. This was used for all p calculations. The " Max." pressure value for testing considerations was 1500 psig.

SUMMARY

The valves and actuators were tested for ability to open against the forces produced by varions 3

pressures at the valve's ports and bonnet areas. The friction factor was measured prior to any

~

testing and periodically checked during the test program. The 3-inch specimen also had its friction factor measured at elevated temperatures.

SUMMARY

(continued) 4 5.1

. Test Setup Description The valves were installed in vertical mounting stands and blind flanges with pressurization ports were installed on the upstream and downstream ends. High-pressure water was supplied from a spherical pressure vessel filled with water and pressurized with a nitrogen blanket. The water was supplied independently to each of the specimen's upstream ports, downstream ports, and bonnet cavities. For the 3-inch valve, a steam supply line allowed high temperature water / steam to be circulated through the specimen to facilitate heating for the high temperature friction factor testing, only. Photographs of the test setup are presented in Attachment 11 of this report.

3 5.2 Receiving Information The valves were received from Grand Gulf and River Bend Stations, via Entergy Operations supplied transportation. Upon receipt, a receiving inspection was performed on each specimen.

No shipping damage was noted.

5.3 Valve Preparation Prior to the initiation of the test program, the 14-inch valve actuator was installed on the valve.

The torque switch was adjusted to produce approximately 80,000-lbs of thrust at wedging.

The 3-inch valve, which was received without strain gages installed on the stem, was

- disassembled $nd the top portions of the valve, along with the stem, werershipped to Teledyne

-s

~ ~ Engineering Services. A Teledyne QSS Quick-Stem was installed and the stem was calibrated '

for tensile and torsional load measurements. The components were returned to Wyle and the specimen was re-assembled for testing. All disassembly and re-assembly was performed by Wyle Laboratories personnel. The torque switch was then adjusted to produce no more than 14,000-lbs of thrust at wedging. The final value was approximately 12,000-lbs.

5.4 Hydrostatic Leakage Testing Prior to any pressure locking testing, the specimens were individually tested for seat leakage and packing leakage using ambient water at 20% of the " Max" pressure value alternately at the upstream and the downstream ports of the valves. The pressure was maintained for 5 minutes in each direction and the opposite port was monitored for leakage. No ' leakage was noted on either specimen across its disc seating surface.

The 3-inch valve initially exhibited severe leakage from the packing leakage port. The old grafoil packing was removed and new braided packing, provided by Wyle, was installed. This eliminated the packing leakage and the specimen then successfully complied with the seat leakage test requirements.

The testing was performed in accordance with references 2.3 and 2.4.

SUMMARY

(continued) 5.5 Baseline Ambient Friction Factor Testing

{

Following the hydrostatic leakage testing, both valves were tested for their friction factor at ambient conditions. While filied with ambient water, the valves were stroked open and closed with 0 psig at all locations, and the wedging and un-wedging forces were measured. The t

i friction factor was calculated by the following formula:

l (WF + UWF) p = tan 0 x (WF - UWF)

Where:

0 is the disc angle (listed in Paragraph 3.0)

WF is th-wedging force in pounds.

I U'WF is the un-wedging force, in pounds.

y 5

s Each of the valves was stroked a minimum of 20 times. The stroking was discontinued after successive strokes were shown to demonstrate a change of no more than 1% from the previous stroke. The testing was performed in accordance with references 2.3 and 2.4.

,.1 The tabular test data for these strokes is presented in Tables I and II of this report.

The graphic test data for these strokes is presented in Attachments III and IV of this report.

5.6 Elevated Temperature Friction Factor Testing (3-Inch Valve Only)

^

~

\\

Following the ambient friction factor testing, the 3-inch specimen was tested for its friction L

factor at an elevated temperature. The specimen was heated by gradually flowing saturated steam through it until the temperature was within 50 F or the saturation point of the test

.8 pressure. The valve was then stroked open and closed and the wedging and un-wedging forces

.d were measured. The friction factor was calculated by the same formula as Paragraph 5.5.

The valve was stroked 30 times. The stroking was discontinued after successive strokes were

/

shown to demonstrate a change of no more than 1% from the previous stroke. The testing was performed in accordance with references 2.3 and 2.4.

]q The tabular test data for these strokes is presented in Table 11 of this report.

The graphic test data for these strokes is presented in Attachment IV of this repcrt.

SUMMARY

(continued) 5.7 Bypass Leakage Testing Following the friction factor testing, both valves were tested for bypass leakage by pressurizing the upstream side of the closed valve until the seat bypassed the pressure from the upstream side into the bonnet cavity and the rate of bonnet pressure increase paralleled the rate of pressure increase in the upstream cavity.

The graphic test data for these tests is presented in Attachments III and IV of this report.

5.8 Bonnet Pressure Testing Following the bypass leakage testing, both valves were tested for opening force while their bonnets were pressurized individually to 331/3%,66%, and 100% of max. test pressure. The inlet and outlet ports were at ambient pressure.

Following the opening stroke at each of the three test pressure, both valves were again tested for their friction factor at ambient conditions by 5 opening strokes. The testing was performed in the identical manner as that of Paragraph 5.5, except that there was no requirement for the friction factor to change no more than 1% between strokes.

All of the testing was performed in accordance with referen'ces 2.3 and 2.4.

Upstream Pressure Testing Following the bonnet pressure testing, both valves were tested for opening force while their bonnets were pressurized individually to 331/3%,66%, and 100% of max. test pressure and the upstream sides were pressurized to 20%, 40%, 60%, 80%, and 100% of the individual bonnet pressure values. A total of 15 strokes were performed,5 at each of the three bonnet pressure values in 20% increasing upstream pressure values. The outlet ports were at ambient pressure.

Following the 5 strokes at each of the three bonnet pressure values, both valves were again tested for their friction factor at ambient conditions by 5 opening strokes. The testing was performed in the identical manner as that of Paragraph 5.5, except that there was no requirement for the friction factor to change no more than 1% between strokes.

All of the testing was performed in accordance with references 2.3 and 2.4.
