20555 IE Information Notice No. 80-11 Date: March 14, 1980 Page 1 of 2 GENERIC PROBLEMS WITH ASCO VALVES IN NUCLEAR APPLICATIONS INCLUDING FIRE PROTECTION SYSTEMS Description of Circumstances: is a Recall Notice from The Viking Corporation, dated July 16, 1979 that identifies ASCO valves used in certain Viking fire protection equipment that could fail.
Liceusees should review their fire protection system components to determine if the equipment identified in the Viking Recall Notice is in their facility.
If the identified equipment is installed in the fire protection system, then the modifications specified in the Recs!1 Notice should be made and tested for proper operation. The requirements of the technical specifications or any other licensee commitment should be complied with when a fire protection system is disabled.
South Carolina Electric and Gas Company (Virgil C. Summer Nuclear Station) reported to the NRC on October 24, 1979, a potentially significant deficiency regarding the effects of oil on elastomeric materials used in ASCO NP-1 solenoid valves.
Specifically, these valves utilize an ethylene propylene elastomer which expands or swells when brought into contact with oils, possibly causing valve failure. For this reason, ASCO specifies these NP-1 solenoid valves for use in " oil free instrument air" systems.
Although instrument air systems are " oil free" by design, installation instructions may specify the use of thread lubricants utilizing an oil base.
Thus, the potential exists for traces of this lubricant from threaded connec-tions in the air system, in addition to traces of oil from the air compressors themselves, to come into contact with the elastomers in the solenoid valves.
Degraded elastomers can cause the solenoid valve to fail by sticking, swelling closed flow paths, or rupturing caus Failure of the solenoid to function a system from performing its require DUPLICATE DOCUMENT Some ASCO NP-1 solenoid valve's are e this valve is equipped with ethylene Entire document previously entered into system under:
