O INTERIM REPORT SIGNIFICANT CONSTRUCTION DEFICIENCY No. 27 "Switchgear Breaker Position Switch Operator Defect" Int'roduction This report is submitted pursuant to 100FR50.55(e). It describes a deficiency in the 4116 KV Class IE Switchgear as modified and installed and is related to Significant Construction Deficiency Report No.- 11 titled "Switchgear Breaker Position Switch Operator Defect."

Description ,

On Marc.h 13, 1981, Louisiana Power & Light Company's Startup Organization advised Ebasco Services, Inc., of a problem with the as-installed breaker position switch operator mechanisms. This deficiency is documented on Nonconformance Report No. W3-2574.

The extent of the deficiency is as follows: The breaker position switch operators have been modified in accordance with Significant Construction Deficiency No. 11 and installed under General Electric's supervision. During sobsequent installation of the breakers, an interference was detected between the operator guide and the breaker arc chute covers which prevents breaker insertion in the gear. This deficiency involves thirty-three (33) breaker position switch operators.

Safety Implications The'as-installed modified breaker position switch operators with the added guides prevent the breakers from being inserted into their respective location.

Therefore, this deficiency if lef t uncorrected could result in an inadequate installation and is considered to be a reportable item under 10 CFR 50.55 (e).

Corrective Action Corrective action required is in the form of an adjustment to the switch operator guide location to permit installation and alignment of the breakers.

The necessary adjustments will be completed and a final report submitted on or before July 31, 1981.
