NRC, "Delay in Completion of Unresolved Safety Issue (USI) A-46 Commitment," dated November 6, 2003 In the referenced letters, Exelon Generation Company, LLC (EGC) notified the NRC of delays in completing actions related to USI A-46, "Seismic Qualification of Equipment in Operating Plants," for Dresden Nuclear Power Station (DNPS), Unit 3. The referenced letters identified a delay in completion of modifications affecting five 250 volt direct current motor control centers and an Automatic Depressurization System (ADS) auto blowdown relay replacement, until the next DNPS Unit 3 refueling outage, D3R18. That refueling outage was recently completed and all remaining SQUG work was completed. This letter documents our closure of this issue.

Should you have any questions concerning this letter, please contact Mr. Pedro Salas, Regulatory Assurance Manager, at (815) 416 - 2800.
