During a telephone conversation held on June 12, 1992, Mr. John Jolicouer of the NRC requesteo additional information relating to the Emergency Response Data System Data Point Library for Farley Nuclear Plant which was submitted in a Southern Nuclear to NRC letter dated February 28, 1992.

Attachment I lists the questions regarding the five parameter data points in question. r. 'dN as Attachment 2 are the revised Reference Files for Units ' and 2.

If time are any additional questions, please advise.
