I o . i T.S.3.1.1.2 required a shutdown margin of 1% A K/K during Mode 5 operation inis,t& FSAR 15.1.4.2.2.3 assumed 2% AK/K shutdown margin for the boron dlutiorg o . Ievent. A review of past shutdown margin calculations in Mode 5 verified i o , I that a greater than 2% AK/K margin had been maintained. No similar
