CAUTION kQ.

Monitor the general state of the plant. Iffan entry condition f'r an Emergency Procedure occurs, enter that procedure. When it that an emergency no longer exists, return to normal plant operating is determined procedures.

CAUTION P3 Monitor RPY water level and pressure and primary containment temperature and pressure from multiple indications.

CAUTION 84 If a safety f'unction initiates automatically, assume a true initiating event has occurred unless otherwise confirmed by at least two independent indications.

CAUTION If HPCS SUCTION SWITCHOVER SUPPRESSION POOL HIGH or HFCS/RCIC SUCTION SWITCHOVER CST LEVEL LOW alarms occur, confirm automatic transfer of or manually transfer HPCS and RCIC suction from the condensate storage tank to the suppression pool. RCIC suction will not auto transfer on high suppression pool level.

CAUTION Do not secure or place an ECCS in MANUAI mode unless by at least two independent indications: 1) misoperation in AUTO-MATIC mode is confirmed or 2) adequate core cooling is assured. If an ECCS is placed in MANUAL mode, it will not in-itiate autcmatically. Make frequent checks of'he initiating or controlling parameter.. When manual operation is no longer required, restore the syst'm to AUTOMATIC/STANDBY mode ii'ossible.

CAUTION If a high drywell pressure ECCS initia-tion signal (1.65 psig) occurs or exists while depressurizing, prevent injection f'rom those LPCS and LPCI pumps not re-quired to assure adequate core cooling prior to reaching their maximum injec-tion pressures. When the high drywell pressure ECCS initiation signal clears, restore LPCS and LPCI to AUTOMATIC/

STANDBY mode.
