Attention:
Mr. L. S. Rubenstein Gentlemen:
Joseph M. Farley Nuclear Plant - Unit 2 NUREG-0737, item II.K.3.17 Report on Outages of Emergency Core Coolng Systems (ECCS)
By letter of February 13, 1981, Alabama Power Company committed to report to the NRC every five years the results of Alabama Power Company's review of the Unit 2 ECCS outages which resulted in limiting conditions for operation as defined by the Technical Specifications.
Attached is the required listing of Unit 2 ECCS outages since May 1, 1981.
It should be noted that outages of ECCS equipment during modes of operation in which this equipment is not required by Technical Specifications are not included in this report.
If you have any questions, please advise.
