(2) r determination will be started when the gross activity analysis of a filtered sample indicates 210pCi/cc and will be redetermined if the primary coolant gross radioactivity of a filtered sample increases by more than 10pti/cc.

(3) Drop test shall be conducted at rated reactor coolant flow. Rods shall be dropped under both cold and hot condition, but cold drop tests need not be timed.

(4) Drop tests will be conducted in the hot condition for rods on which maintenance was performed.

(5) As accessible without disassembly of rotor.

(6) Not required during periods of refueling shutdown.

(7) At least once per week during periods of refueling shutdown.
