DO !;0T SECURE or PLACE an ECCS or RCIC in manual mode UNLESS by at least two~

1 dependent indications:

1. Misoperation in the automatic mode is confirmed. ORi

2. Adequate core cooling is assured.

IF an ECCS or RCIC is placed in the manual mode, it vill NOT initiate '

automatically. MAKE frequent checks of the initiating or controlling !

parameter, kHEN t snual operation is tio longer required, RESTORE the system toautomatic / stand'; mode if possible.**e*********************e****************enae******enene***ene***eeeena*******

1. RESTORE and MAINTAIN reactor vessel level between +170 and +200~~ ,

inches. USE one or more of the following systems in an order that{vill minimize high eenductivity feed to the reactor:,

2. IF the CRD Drive Water Pressure Control Valve, C11(C12)-F003, andthe in-service CRD Flow Control Valve, C11(C12)-F002A(F002B), havebeen opened to maintain reactor vessel level b3D the CRD System isno longer needed to maintain reactor vessel level, THEN PERFORM thefollowing steps to restore the CRD System to normal operations

a. SET the setpoint tape on CRDHS Remote Flow Controller,~~ 'C11(C12)-FC-R600, to 100 spm.
