Page 2 May 17, 1985 U.S. Nuclear Regulatory Conmission he Engine Generator Control Panels were purchased by Transamerica Delaval fr a RIE DELTA of Stockton, California. Some of the cm-ponents were furnished by the Generator Manufacturer (NEI Peeples-Electric Products, Inc. of Cleveland, Ohio) for installation in the Generator Control Panel'by RTE DELTA.
We potential problem with the Control Panel is overheating, which could lead to failure of some components.
We reconmend that each Site review their Generator Control Panel installation for this potential problem.
If this review indicates the problem exists, changes made to the installation may solve the overheating situation. Reducing the j
anbient tenperature, operating with the doors open, or other things which will reduce heat rise are suggested.
In the event that it is not possible to eliminate the problan by site changes, fan assenblies for inproved ventilation can be in-stalled in the cabinets. L e installation of forced ventilation has been reviewed by our Engineering Department and the Control Panel Manufacturer. We design for forced ventilation is couplete.
If required, we will furnish all material, instructions and service on request, to complete this revision in accordance with each individual contract.
A copy of this letter will be sent to each site listed in paragraph l
2 as shown by the cc's.
Our evaluation of this untter was completed on May 16, 1985.
Since correction of this potential defect depends on action by others, we cannot estiaate whm the action will be complete.
Very truly yoors, g l2)
