Subject:

Quad Cities Station Units 1 and 2 Schedule Changes for Implementation of Human Engineering Deficiency Corrective Actions NRC Docket No. 50-254/265 Dr. Murley ,

The purpose of this letter is to identify a schedular change for the ,

completion of corrective actions associated with human engineering deficiencies. ,

In order to resolve Human Engineering Deficiency (HED) Index Numbers 159 (6.1.1.2),187 ~6.1.1.3), 352 (6.3.8. A.1) and 489 (6.3.8. A V 2), the escutcheon plates for control switches need to be replaced. The replacement of control switch escutcheon plate requires the removal of the control switch ,

handle and the screws which secure the control switch to the panel. Quad Cities Station has determined that performing this task during normal plant  ;

operations is not desirable and, therefore, a niit outage would be required. i This task was scheduled to be completed during the recent Unit 1 outage; i however, due to manufacturer's delays in a=11vering the plates, the replacement could not be completed. Tho HEDs are categorized as 30.

The implementation of corrective a:tions associated with these HEDs will be completed during the Unit 1 Outage currently scheduled for October, 1990.

Quad Cities will attempt to replace the escutcheon plates prior to the Unit 1 outage if an outage of sufficient duration occurs prior to October, 1990. ,

Temporary labels have been provided for control switches which were incorrectly labeled.

Please direct any questions or comments concerning this subject to R.
