6835 Accession Na.:

8008220245 IN S0-39 IE INFORMATION NOTICE NO. S0-39: MALFUNCTION OF SOLENOID VALVES MANUFACTIJRED BY VALCOR ENGINEERING CORPORATION PURPOSE:

The intent of this Information Notice is to alert holders of construction permits and operating licenses for nuclear power plants of a.potentially generic problem involving the malfunctioning of certain solenoid valves manu-factured by the Valcor Engineering Corporation (Yalcor).

The solenoid valves so. involved are designated as Valcor Valve Modal No. V52600-554-l.

Valcor' has informed us that these valves have only been supplied to the Mc!iuire facility; however, since tttese valves were substituted for solenoid valves of another manufacturer that did not meet the requirements of IE Bulletin. No. 79-01 and its amendments, licensees and holders of construction permits should take into account the problem identified in this Information Notice prior to making any similar substitt.ation.

BACKGROUND:

By TWX datad June 27, l.SSO, Valcor submittad a preliminary 10 CFR Part 21 Report addressing the malfunctioning of Valcor solenoid valves at the McGuire faci 1 ity.

The malfunctioning valves have been i de.ntified as Valcor Valve Model No. 52500-554-l.

This lW'X was subsequently fol 1 owed by a 1 ettsr dated July 3, 1980, transmitting a more detailed Part Zl Repol"'t entitled,"Quality Assuranca Report11, a copy of which 1 s attached hereto as Enc 1 osure No. l.

In brief, the malfunction appears ta be an intarmittent type wheM!in the valve fails ta cycle from OPEN to CLOSE ta OPEN immediately attar a sustained period of operation in the energized (OPEN) mode.

Although the valves ar1! rated for "ccntinucus operation11, Vale.or contends that the valves weM! net* designed to meet the operating conditions requiring the immedi'ate cycling fl'mlJ.OPEN tJl CLOS£ tJl OPEN after a sustained period of continuous energization.

A major soun:e of the prtJblem, therefoM!, may be a misunderstanding of the term

    • continuous operationu.

By letter dated July 14, l.SSO to Duke Power Ccmpany, Valc:ir transmitted its recommendations in this matter entitled, "Outline -

Suggested Modification Proc:edures11, a copy of which is attached hereto as Encl asun No *. 2.
