| event text = On May 31, 2013 at 0712 [EDT], Unit 2 [reactor] was manually tripped due to high differential pressure on the debris filter for the 2A1 Condenser Waterbox which required a trip of the 2A1 Circulating Water Pump. The 2A2 Condenser Waterbox and the 2A2 Circulating Water Pump were already removed from service due to a suspected condenser tube leak. | | event text = On May 31, 2013 at 0712 [EDT], Unit 2 [reactor] was manually tripped due to high differential pressure on the debris filter for the 2A1 Condenser Waterbox which required a trip of the 2A1 Circulating Water Pump.

All CEAs [Control Element Assembly] fully inserted into the core. Decay heat removal is from main feedwater and steam bypass to the main condenser. The cause of the rising differential pressure on the 2A1 debris filter was potentially due to an influx of algae. | All CEAs [Control Element Assembly] fully inserted into the core.
