The LCO is modified by a Note that identifies that the V-notch sump inlet flow monitoring system is not required to be OPERABLE provided the drywell floor drain sump flow is monitored and determined at least once per 8 hours. This Note only applies until the first shutdown to MODE 4 afler March 15,1994. Prior to plant restart from that plant shutdown, the V-notch sump inlet flow monitoring system must be restored to l               OPERABLE status.
