I.

Purcose:

r This test program was developed as part of A/DV's response to NRC and utility concerns regarding the closure ability of critical service gate valves in the event of a catastrophic line break.

Such concerns are required to be addressed by utilities in response to Generic Letter 89-10, issued by the NRC.

Although the majority of the A/DV gate valves currently in service in such critical applications are flexible wedge gate valves, A/DV believes that its double disc design is more suitable for such - severe service.

Therefore, A/DV's double disc gate valves can be installed as a resolution to this concern.

The specific objectives of this test program were to demonstrate the ability of A/DV's 6"-900-DD gate valve to close under full blowdown conditions; to determine if the valve would sustain notable damage; and to determine the l

required stem thrust and corresponding valve factor

{

i required to isolate flow.

The results of this test program are intended for use as a basis for qualifying other models of the A/DV double disc gate valve for similar applications.

The susceptibility of the double disc gate valve to thermal binding was also investigated.

l II.

==

Conclusions:==

The cycle tests performed prior to the blowdown tests demonstrated the durability of the valve design.

The results of the blowdown testing of A/DV's 6"-900-DD gate valve have determined the following:

The valve was capable of closing and isolating flow under blowdown conditions; The valve did not sustain any notable damage throughout the testing; Seat leakage tests performed subsequent to l

each blowdewn demonstrated the capability of l

the valve to maintain seat tightness after i

blowdown closure; Calculations, based on the test data for the most severe conditions, reveal a valve factor of less than 0.32 at ficw isolation; 1

4

A j

Tho tost velvt was not suscGptibio to thermal binding-an d:monstratsd by the successful l

openings of the valve subsequent to het blowdown closures.

The test program demonstrated the suitability' of the A/DV double disc gate valve for severe vrvice conditions such j

as those present in high energy systems where blowdown conditions could occur.

III.

Valve

Description:

The valve design that was tested is an Anchor / Darling 6"-9004-DD rising-stem motor operated gate valve.

(See l

below for a tabulation of specific information.)

The i

valve was manufactured at the A/DV faci'lity_

in Williamsport, and was subjected to complete dimensional and visual inspections prior to assembly.

The test valve reflects the current A/DV design.

The basic design features of the test valve appear in other sizes of A/DV double disc gate valves.

The operator installed on the test valve was selected based on availability, and does not necessarily represent the size of actuator normally recommended by A/DV for this valve.

The test valve was equipped with a Teledyne SMARTSTEM.

Des.cription of Preliminary Testina at A/DV:

Prior to the performance of the blowdown testing at Wyle Labs, the test valve was subjected to cycle testing per A/DV standard procedure EPS-191 R/.

This testing consisted of fifty (50) opening strokes against 1500 psig differential pressure, and fifty (50) closing strokes

.under 1500 psig internal pressure.

Seat leakage tests were performed at 1500 psig after every ten (10) cycles.

Air seat tests were performed both before and after the cycle tests.

All tests were satisfactory.

The test valve was disassembled and inspected for wear and/or damage following the completion of the tests. No wear or damage was apparent.

Cycling of the valve was performed as a

pre-conditioning ~

exercise to eliminate the possibility of operability enhancement due to the presence of oxides or lubricants during the initial blowdown cycles.

y V.

Description of Wyle Testino:

The test valve was shipped to Wyle Labs in Huntsville, Alabama; where it was subjected to a series of cold and

-hot blowdown tests in accordance with Wyle procedure no.

41854.

The test valve was instrumented per Wyle test procedure 41854.

All equipment was calibrated prior to use.

The valve was closed under high energy blowdown flow at various nominal system conditions.

valve opening was performed under a differential pressure of either 0 psig, or 1400 psig.

The testing consisted of a baseline seat leakage test, six (6) blowdown tests under cold conditions, and five (5) blowdown tests under hot conditions.

Seat leakage tests were performed following each blowdown test.

For the hot blowdown tests, the valve was allowed to cool to less than 100 degrees F prior to performing the seat leakage tests.

The valv9 was then re-opened and disassembled for visual inspection. For the hot blowdown cycles, the opening stroke served as a test for thermal binding.

A summary of the series of tests performed appears in Appendix 1.0.

VI.

Test Results:

The results of this report are based on the data acquired from the Teledyne SMARTSTEM, and associated data acquisition equipment.

All equipment was calibrated prior to use.

A summary of basic data for all of the blowdown cycles is presented in Appendix 2.0.

The graphical data and expanded tabular data presented is for the second of five hot blowdown tests performed.

Complete test data is available for review at A/DV.

The t,est valve successfully isolated the flow under the referenced conditions for all tests.

The stem thrusts provided in Appendix 2.0 are based on data obtained at the point of flow isolation.

Visual inspection between blowdown cycles revealed no significant wear or damage, although slight burnishing of the disc and seat ring became apparent by the final blowdown cycle.

Seat i

leakage rates for the downstream seat were less than 0.02 cc/ min for the first six blowdown cycles.

The leakage l

rate ranged from 0.4 cc/ min to 1.4 cc/ min following blowdown tests #7 through #9.

Considering the quantity l

and severity of the tests parformed, A/DV found these results more than satisfactory.

{

The valve factors tabulated in Appendix 2.0 were determined from the standard industry equation as shown below.

This. formula may be employed to verify the tabulated results.

T,=T,+ T.+ ( k

• A,

• DP )

or p= (T -T,-T,i/ (A,*DP) where:

T,= stem thrust required to isolate (lbs)

T,= packing friction, lbs T,= stem and load, lbs

= valve factor A,= seat area, based on mean seat diameter, ina DP= differential pressure 4

i The stem thrust required to isolate, packing friction, differential press'ure, and stem and load are be based on experimental data gathered from the actual blowdown test.

The. seat area is based on the design dimensions of the valve.

The actual packing friction is based on running loads measured under static conditions during an opening cycle that followed blowdown closure.

There were no packing adjustments made between the open and closed cycles.

Appendix 2.0 also presents valve factors based on packing friction established according to standard industry practice.
