TABLE NOTATIONS (Continued) l (k) Will automatically close when a) RCIC Turbine Steam Stop Valve E51-F045 closes or b) RCIC Turbine Governor Trip and Throttle' Valve E51-F059 closes.
-(1) Will automatically close as'a result of the conditions listed in Note (k) above, as well as when RCIC flow is greater than 130 gpm.
(m) These valves are actuated by remote manual key-locked switches and will cut the TIP cable and seal off the TIP guide tube when actuated. These valves are squib-fired.
(n) May be closed remotely asfa secondary actuation mode to reverse flow.
i (o) Valves realign automatically on a reactor scram signal.
