Dear Mr. Keppler:

This letter serves as an interim report pursuant to 10CFR50.55(e) on the.-

potential design deficiencies associated with the buildup of condensate in the Reactor Core Isolation Cooling (RCIC) System. Mr. J. McCormick-Barger of your office was notified on January 23, 1985, by Mr. T. A. Boss of The Cleveland Electric Illuminating Company that this problem was being evaluated per our Deviation Analysis Report 220.

This report contains a description of the deficiency, actions planned to complete our evaluation, and the planned date for our next report.

Description of Deficiency Two locations exist in the Reactor Core Isolation Cooling steam supply line where condensate can collect upstream of a valve and the Residual Heat Removal steam condensing lines. Upon initiation of the RCIC system the valve is opened and system pressure could cause a slug type flow of the condensate.

Completion of Evaluation Gilbert / Commonwealth, Inc., our Architect / Engineer, is performing an analysis to determine the potential effects of the slug flow on the operation of the RCIC system.
