TABLE NOTATION..

With the reactor trip system breakers in the closed P,~sition and tbe control rod drive system capable of rod withdrawal.

The channel(s) associated with the protective functions derived from the out of service Reactor Coolant Loop shall be placed in the tri.?ped cqndition:..

Th~ provision~* 'of Specification 3.0.4. are not applicable.

High voltage to detector may be de-energized above P-6.

If ACTION Statement 1 is entered as a result of Reactor Trip Breaker.
