located inside the contairment in accordance with IE Bulletin 79-14.

As of this date, Florida Power. Corporation hoe cospleted the inspection of four (4) of the nine (9) KB spray rings located in the top of the contatteent g

building.

Rings rnmebered 4.~ 7. 8,' end 9 have been inspected in accordance j

with TTC's Icepection Frogram and the requiremente of IE Eulletin 79-14.

t 1

The detailed inspection of the sprey rings requir'ed three (3) days for each rirg se they are entrenely difficult to reach for inspection due to their j

location in the top of the containment building.

Our post esperience indi-cotes that the inspection of the ressining five (5) errey rinas would re-quire an additional fiftcen (15) days inside contairnent.

i l

riorida Power Corp' oration hereby requeste en amen) tion fron the inspectio'n 1

of the r'essining five (5) apray rings.

This exemption is justified for the ic11owins reasoner

inspection.
