, Docket Nos. 50-327 and 50-328 Alert Soddy-Daisy, Tennessee Site Area Emergency General Emergency X Not Applicable
SUBJECT:
SHUTDOWN GREATER THAN 48 HOURS TVA's Manager of Power and Engineering informed the Regional Administrator today that he has directed the orderly shutdown of Sequoyah Units 1 and 2.

Preliminary plans by TVA are for Sequoyah Unit 2 to be taken out of service today and to proceed to cold shutdown. Unit I will be taken out of service once Unit 2 is in a stable shutdown condition.
TVA plans to announce the shutdowns today. Region II is prepared to respond to inquiries.
