4.5 If (15\ power and all main feedwater flow is lost, the Ss00 will determine if a reactor trip is required, (i.e. ,
if the cause of the loss of T.W. is apparent and it can be readily restored and the transient caused by Erd actu-atica is minimal).
4.6 There aust be at least three (3) RC pumps (RCP's) in operation while in Mode 1 and/or 2.
4.7 Trip the reactor if:
- a. Two (2) or more main steam tsolation valve's (.wSIV's) are closed.
- b. Pressurizer level goes above 290-in.
4.8 A trip of bo th sain f eedwater pumps (MrdP's) at pe e r levels > 20% will cause a reactor trip.
4.9 A trip of the sain turbine at any power level ) 30*. will cause a reactor trip.
41 4.10 For work located in Radiation Controlled Areas due consideration should be given to the A!. ARA Progran. This say result in a determination that special precautions and/or preparations are necessary.
4.11 If SUV-9 is used to lower deaerator level during startup, OTSG levels should be closely zonitored. Opening SUV-9 too far will divert all feedwater flow to the condenser I hotwell.
