NOTE

RCS leakage to CC in the letdown coolers may be indicated by a cooler outlettemperature increasing more than the other cooler. Due to CC system setup,letdown cooler CC outlet temperatures may be different. A historical OACtemperature trend may be required to determine if leakage exists and if actionstaken are successful in leak isolation. If leaking cooler CANNOT be identified,the coolers will be isolated one at a time starting with the 1A Letdown Cooler.

EXAMINER NOTE: Initially, ES Channels 1 and 2 will actuate when RCSpressure decreases below 1600 psig. When Reactor Building pressureincreases to > 3 psig, ES Channels 3-6 will actuate. The exact paththrough End. 5.1 is somewhat dependant on timing of ES 3-6 inconjunction with the pace of progress through the enclosure. If the ROreaches Step 15 prior to ES 3&4 actuation, the procedure directs going toStep 53.
