Division of PWR Licensing-S FROM: John Stolz, Director PWR Project Directorate #6 Division of PWR Licensing-B ,

SUBJECT:

OUTLINE FOR THE RANCHO SEC0 NUCLEAR GENERATING STATION RESTART SAFETY EVALUATION REPCRT Enclosed is the draft outline for the Rancho Seco restart safety evaluation report (SER) including a preliminary assignment of responsibility (by branch) for the writing of the specific sections which make up the SER. Please review the draft SER outline and the indicated branch assignments for each SER section and identify reviewers responsible for each SER section input. Please provide me with any comments you may have by COB September 11, 1986.

We have provided preliminary copies of the outline to Region V and to IE for their comments and will coordinate them in finalizing the SER outline. We are also coordinating with DHFT in the areas of maintenance, training, and human engineering reviews.
