' STORAGE TANK ,-

This technical review report completes my investigation into inadvertent c losses of inventory from condensate storage tanks. The investigation was-lj prompted by an event at Browns Ferry-1, where 192,000' gallons of non-safety ~ ,

s tinventory was' lost due to untimely responsive action. A review of other '

?

events indicated the Browns Ferry event was typical of a previously l

, established pattern'of CST draindowns,at BWRs, and these. operational  !

- events'did not affect plant safety. l H
