1 of 1 SINGLE PASSIVE FAILURE ANALYSIS - EMERGENCY CORE COOLING SYSTEM RECIRCULATION PHASE Flow Path Indication of Loss of Flow Path Alternate Flow Path COLD LEG From containment recirculation sump to low head cold leg injection header via the residual heat removal pumps and the residual heat exchangers.

Reduced flow in the discharge line, from one of the residual heat exchangers (one flow monitor in each discharge line) and/or leakage sump level alarm Via the independent identical low head flow path utilizing the pumps second residual heat exchanger HOT LEG From containment recirculation sump to hot leg low - head injection header via RHR pumps and RHR heat exchangers.

Same as above Same as above COLD LEG From containment recirculation sump to the high head cold leg injection header via the west residual heat removal pump, west residual heat exchanger and the safety injection pumps.

Reduced flow in the discharge lines from the safety injection pumps (one flow monitor in each discharge line) and/or leakage sump level alarm.

From containment recirculation sump to the high head cold leg injection headers via east residual heat removal pump, east residual heat exchanger and the centrifugal charging pumps cross - tie to SI pump suction.

HOT LEG From containment recirculation sump to the high head hot leg injection headers via west residual removal pump, west residual heat exchanger and the safety injection pumps.

Reduced flow in the discharge lines from the safety injection pumps (one flow monitor in each discharge line) and/or leakage sump level alarm.

From containment spray to the high head hot leg injection points via East residual heat removal heat removal pump, East residual heat exchanger and the centrifugal charging pumps cross tie to SI Pump suction
