f5 TT11 It has been determined that an overstress condition exists on an unisolable drain gi line and an isolable purification line to the refueling cavity during a seismic l IoI4IIevent.

Failure of the drain'line could cause partial loss of the biological shield l l

l o I s l l depth during refueling; however, the level drop would be slow enough to permit I

ITTT1 I reinserting anv fuel element beine moved before a oroblem develops. There are no l

g l consequences predicted for the purification line.
