Title

Predicted Plant Response to Large transient With ICS

Description

An URI was identified concerning the predicted plant response to large transients using the newly implemented ICS. On May 14, 2010, during the performance of a condensate pump trip test, Unit 1 experienced a level transient and reactor scram on a main turbine trip. Despite simulator predictions that the ICS would handle the recirculation runback and associated level transient, the ICS did not respond sufficiently. PPL was conducting an RCA of the scram event at the end of the inspection period. This issue will be tracked as a URI pending inspection following completion of PPL\'s RCA.
