This is an interim report of a potentially reportable item under the provisions of 10CFR50.55(e). Our latest interim report, logged TXX-6404, was submitted April 24, 1987.
Collection of the Unit 1 as-built data is complete..To date, 39 Nonconformance reports (NCRs) have been initiated for 133 overfilled sleeves.
We are continuing our evaluation of this issue with regards to cable derating, cable pulling-tension, fire seal integrity, divisional train separation, system interaction and installation verification criteria.
Our next report-on this issue will be submitted no later than January 11, 1988.
