SUMMARY

SUBCATEGORY / ELEMENT . 241.4( B)

This conccrn is considered specific to SQN. It is not considered a restart issue since the "old" vendor supplied defective Amphenol connector assemblies on the actuators of the standby diesel generator have already been replaced with new corrected connector assemblies (Ref.

MR Nos. A539668 thru A539671). Since, the issue of the concern has been corrJcted, there will be no failure to the safety related standby diesel generator caused by the connectors.
