Attachment A
The following information supplements the discussion presented in Section 5.2 of the Incident Evaluation, Steam Generator Tube
- Rupture, submitted to the NRC by letter dated April 13, 1982.
The instrument air system used in the EPRI PORV testing programs contained an ASCO NP 8316 with a Cv of 5.5.
This solenoid valve was remotely mounted and is a model identical to valves SV 8620ASB used in the Ginna PORV instrument air system.
The exhaust port on the solenoid valves in the EPRI system was not restricted.
(2)
(3)
Ginna solenoid valve SV 8620A is located approximately 88 inches away from PORV PCV-430.
Solenoid valve SV-8620B is located approximately 83 inches away from PORV PCV-431C.
The elastomer used in the SV-8620 A88 solenoid valves is ethylene propylene.
(4)
Following the initial removal of SV-8620A from the PORV air supply. the solenoid valve was disassembled, inspected and reassembled.
All internal components were found to be in satisfactory condition and were re-used in the reassembly.
(5)
The full travel of the solenoid valve diaphragm is approximately 1/32 of an inch. It is calculated that a change in temperature of 2 F is sufficient to cause a
1$ movement.
(.0003") of the diaphragm due to solenoid valve body expansions (6)
The instrument air system supply at Ginna consists of three oil free air compressors, with after coolers, air receivers, and instrument air dryers with prefilters and afterfilters.
During normal operation one instrument air compressor provides sufficient air for the instrument services and normal air pressure should be between 100 to 125 psig.
An automatic valve connects the service and instrument air system to provide a back-up supply in the event instrument air system pressure drops below 90 psig.
The service air system compressor is not oil free, however, the prefilter ahead of the air dryer will remove 99% of all incident. oil at those times when service air enters the instrument air system.
(7)
The solenoid valve which had been installed in service as valve SV-8620A, and a similar valve from stock, were tested to investigate possible failure mechanisms.
These tests are described in NUREG-0909, "NRC Report on the January 25, 1982 Steam Generator Tube Rupture at R. E. Ginna Nuclear Power Plant" on pages 7-23 to 7-27..
Briefly, the testing which was performed is as follows.
II,
a)
The SV-8620A solenoid valve was tested in the Instrument
& Control Shop using the same exhaust restriction when the valve was in place in the air system.
Using this restriction and alternately energizing and de-energizing the solenoid, it, was not possible to cause the valve to malfunction.
b)
A small valve was then placed in the outlet of the solenoid valve exhaust port to further restrict, the exhaust flow.
The exhaust port flow was then progressively restricted until the solenoid valve malfunctioned.
With this restriction, the de-energized solenoid valve would retain "cylinder" port pressure and was repeatable approximately 3 times out of 10.
c)
The solenoid valve was reinstalled in the air supply to the PORV and the exhaust port restriction was replaced once again with a small valve.
Results similar to the bench tests were obtained with the solenoid valve "cylinder" port pressure being retained, but with no increase in pressure.
In all of these tests, a
severely restricted exhaust was required to produce malfunction.
d)
The next set of bench tests was performed on a similar model ASCO valve from stock.
This valve was tested with an air chamber to simulate the PORV actuator and with a small valve to simulate the exhaust port restriction.
The results of this testing were similar to that previously achieved with one significant additional observation.
With the exhaust port outlet restriction open just enough to allow valve operation, the valve was de-energized.
As soon as the valve began venting out the exhaust port, the port was further restricted.
This caused the pressure in all ports to increase back to supply pressure.
The valve remained in this condition until the exhaust port was re-opened to greater than the original restricted area.
This type of action closely reassembled that which would be required to cause the PORV to start closed and then reopen.

DESCRIPTION Bullctln 8316 valves with Prefix "NP" ln the catalog number are 3-way diaphragm.operated, pUotwontroUed solenoid valves designed as nuclear power plant PUot valves. Valves are of brass construction with only four moving parts a core asscrnblyr two diaphragm assemblies and a disc holder sub.assembly.
Internal valve parts are of stainless steel/ethy)ene propylene for oU.free, or stainless steel/VITONG construction for non-oU free Instru-ment air service (Suffix "V").Valves may have a Watertight, NEMAType 6 Solenoid Enclosure, or they may be equipped with an Explosion-Proof/
Watertight Solenoid Enclosure which is designed to meet NEMA Type 4 Watertight, NEh'IA Type 7 (C or D) Hazardous Locations Class I ~ Groups C or D and NEhIA Type 9 (E, F or G) Hazardous Locations Class II, Groups E, F or G. Installation and Maintenance Instructions for this sole-noid enclosure are shown on Form No. V6380.
OPERATION NonnaUy Closed Solenoid De~nerg)zad: Flow is from Cylinder "A"to Exhaust "Esn Pressuxe "P" connection is closed.
Solenoid Energized: Flow is from Pressure "P" to Cylinder "A."Exhaust "E" connection IS closed.
Normally Open Solenoid Desenergized: Flow ls from Pressure "P" to Cylinder "A."Exhaust "E" connection ls closed.
Solenoid Energized: Flow ls from Cylinder I'A"to Exhaust "E." Pressure "P" connection is closed.
NOTE: To change from normally closed operation to normally open oper-ation, thc brass pUot Insert and disc holder spzing must be zeplaced. Con.
suit ASCO.
NDAMALLYCLOSED FLOW DIAGRAMS PIPING Connect piping or tubing to valve according to maxldngs on valve body.
Refer to flow diagrams provided. CAUTION: Valves supplied for oU.free Instrument ah service are equipped with ethylene propylene elastomcrs which can be attacked by oUS and greases.
Wipe tha pipe threads clean of cutting oils. This precaution does not apply to valves with Viton elastomers (Suffix "V"ln catalog numbers). Piping to all valve ports should be oriented such that any accumulated moisture (Particularly LOCA chemical sPray) wUI not enter the internal areas of the valve. For appUcations where ex-haust piping is not required, instaU a downwardWrected street elbow ln the valve exhaust port. Apply pipe compound sparingly to male pipe threads only: if appUed to valve threads, It may enter the valve and cause operational difficulty. Pipe strain on valve body should be avoided by proper support and alignment of plplng. SVhen tightening connections, do not use valve body or solenoid as a lever. Wrenches applied to valve body or piping aze to be located as close as possible to connection point.
To insure proper operation of the valve, the pressure and exhaust lines ~
- must be fuU area without restriction. A minimum differential pressure as ~I stamped on tha nameplate must be maintained between pressure and ex-haust at the moment of changeover. Air reservoirs must have adequate capacity to maintain this minimum pressure during changeover. To check pressure during changeover, Install a pressure gauge ln the pressure connec-tion as close to the valve as possible.
IMPORTANT: For thc protection of the solenoid valve, lnstaU a strainer or fUtcr suitable for the service Involved in tha inlet side as close to the valve as possible. Peziodlc cleaning ls zequ)*cd depending on service conditions.
See Bulletins 8600 and 8601 for stralners.
As an additional precaution against malfunction on start.up, resulting from large paztlcles of pipe scale, weld splatter, ox other debds ln pipe line, these valves have a large.mesh screen (not a tilter) at inlet. This screen.)s not a substitute for the stralners or IUters zecommended above, whose function is to provide continuous straining or filtration of the Une fluid.
P FLOW CONTROLS (Speed or Metering Devices)
Flow Control Valves (Speed or Metering Devices) may bc added to allow full unrestricted flow in one direction and controlled flow in the opposite direction. These flow control valves must bc located ln CyUnder "A"piping between the solenoid valve and the cylinder. IMPORTANT: Do not Install Flow Controls (Speed or hfeterlng Device) or any type of restrict)ve device ln either the Pressure "P" (inlet) connection or the Exhaust "E" (outlet) connection of the valve. Restricting either of these )inca may cause valve malfunction.
WIRING Wiring must comply with all applicable Local and National Electrical Codes.
Housings are provided with a 1/2 NPS or 3/4 NPT conduit connection.
Connect wring through a conduit of suitable quality for thc expected
'nv)xonment to a vented electrical )unction box located in the same area as the valve. The conduit/junction box system should be oriented such that any accumulated mo)stuxe or LOCA spray wUI not run Into the solenoid enclosure. Thc watertight solenoid enclosure may be rotated to facUltate wiring. Refer to Form No. V5380 for the method used to rotate the explosion proof/wateztight solenoid enclosure.
NOTE: Altcrnatlng Current (AN) and Direct Current (DN) solenolds arc buUt differently. To convert from one to tha other, lt Is necessary to change the complete solenoid, including the solenoid base sub.assembly and core asscrnbly.
SOLENOID TEMPERATURE Standard catalog valves are supplied with coils designed for continuous-duty service. When the solenoid is energized for a long period, the solenoid enclosure becomes hot and can be touched with the hand only for an in-stant. This is a safe operating temperature. Any excessive heating wUI be Indicated by the smoke and odor of burning coil insulation.
MAINTENANCE WARNING: Tum off electrical power supply and dcpressuxlza valve before making repairs. It Is not necessary to rcmove the valve from tha pipe line for repairs.
CIGAGING Ap ldl I
