'DATE OF EVENT: August 12, 1980, FACILITY: Davis-Besse Unit 1 IDENTIFICATION OF OCCURRENCE:.'Non-Qualified ~ Solenoid Valve Operator Installed on Containment Purge Valve Conditions Prior to Occurrence: The unit was 'in Mode 5 with Poser (MWT) = 0 and Load (Gross MRE) w 0.

Description of Occurrence: On August 12, 1980 at 0900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br />, Inscrument and Controls (I&C) personnel were comparing a suspected bad solenoid valve with a known good one, SV5005.- This good valve,-.SV5005, controls the Containment Purge Inlet Isolation Damper CV5005.- A check of I&C calibration and maintenance records showed that SV5005 was installed August 26, 1976 for temporary use and was never replaced with the proper valve. -This temporary valve is not qualified for nuclear service and is not accepta-ble in this application.

Therefore, CV5005 was declared inoperable and secured in its closed position.

Being a Safety Features Actuation System (SFAS) incident icyc1 1 valve, CV5005 must be operable in all modes, and therefore, the station entered the action statement of Tech-nical Specification 3.3.2.1.

This action statement required the valve to be secured in its safety position, closed.

Designation of Apparent Cause of Occurrence: The cause was an inadequate implementation of an administrative control during the initial plant testing and system turnover. At -

the time.the valve was installed, it was known that it wat for temporary use. I&C's Instrument Information Sheet shows that at the time of the installation, it was known that this solenoid-valve was installed for temporary use until a proper valve -was received. The installation of this temporary valve without proper documentation was not in complianceDwith the administrative requirements of AD 1844.00, " Maintenance".

Analysis of Occurrence: There was no danger to the health and safety of the public or to station personnel. The installed valve did function properly in all testing since it was installed.

Corrective Action

An ongoing review of I&C records is being conducted to verify that there.had been no other maintenance activities conducted during initial startup and testing that'were completed without conforming to the administrative requirements

~

ofLAD~1844.00. No additional discrepancies have been found.

On: August 12,;1980 when it was determined that the installed SV5005 solenoid valve i

. as not qualified for its application, CV5005 was declared inoperable and secured

~

w in.its closed position'.- The valve will remain closed until a suitable replacement is installed. Nonconformance Report 292-80 was-issued to ensure a qualified solenoid LER 180-061 q

valve is used. ' Facility Change Request 80-206 has been written to replace SV5005-

.with-an available nuclear service grade solenoid valve.

Failure Data: There have L$en no previous reports of this type damper being declared' inoperable due.to the installation of a non-qualified solenoid valve.
