(b) These valves are hydrostatically leak tested.

(c) NCU Water Temperature - High automatically closes G33-F004, outboard isolation, and G33*F001, inboard isolation.

(d) Also closes automatically as a result of Torus Room Floor Drain Sump Level - High - High and Drywell Floor Drain. Sump Leve.1 - High - High.

(e) These valves may be closed remotely from or,e of the following locations:

1) control room.

2) their respective local panels.

(f) Will automatically reposition as a result of the actuation of the LPCI loop Selection Logic.

(g) Will automatically close when the corresponding RHR loop flow is greater than 1500 gpm.

c (h) ilill automatically close when the corresponding core spray loop flow is greater than approximately 775 gpm.

5 (i) Will automatically close when a) HPCI Turbine Steam Stop Valve E41-FC67 closes or b) HPCI Turbine Steam Supply Isolation Valve E41-F001 closes.

(j) Will automatically close as a result of the condition listed in Note (i),

abovp, as well as when HPCI flow is greater than 1200 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 as a secondary actuation mode to reverse flow.
