20555 IE Bulletin No. 79-01 Date:

February 8,1979 Page 1 of 3 ENVIRONMENTAL QUALIFICATION OF CLASS IE EQUIPMENT Description of Circumstances:

The intent of IE Circular 78-08 was to highlight to all licensees important lessons learned from environmental qualification deficiencies reported by individual licensees.

In this regard, licensees were requested to examine installed safety-related electrical equipment and determine that proper documentation existed which provided assurance that this equipment would function under postulated accident conditions. The scope of IE Circular 78-08 was much broader than other previously issued Bulletins and Circulars (such as IEB 78-04 and IEB 78-02) which addressed specific component failures.

The intent of this Bulletin is to raise the threshold of IE Circular 78-08 to the level of a Bulletin; i.e., action requiring a licensee response.

Inspections conducted to date by the NRC of licensees' activities in response to IE Circular 78-08 have identified one component which licensees have found to be unqualified for service within the LOCA environment.

Specificially, unqualified stem mounted limit switches (SMLS), other than those identified in previously issued IE Bulletin 78-04, were found to be installed on safety-related valves inside containment at both Duane Arnold and Quad Cities 1 and 2 Nuclear Generating Stations.

The unqualified switches are identified as NAMC0 Models SL2-C-ll, S3CML, SAI-3I, SAI-32, D1200j, EA-700 and EA-770 switches.

According to the manufacturer, these switches are designed only for general purpose applications and are not co'nsidered suitable devices for service in the LOCA environment.

Consequently, switches are being replaced at the above Dewer plants with qualified components.

Also, nkC inspection of component qualification has identified equipment which does not have documentation indicatina it is qualified for the LOCA environment.
