I.ER ATTACIDfE!.'T - RO # 1-80-76 Facility:

BSEP Unit No. 1 Event Date:

10-22-80 The f ailure of the magnetic analyzer sample cell was a result of corrosion in the analyzer intake screen that was caused by excessive moisture in th; analyzer sample line. Due to a history of similar problems involving this type of analyzer, a plant modification has been written to replace these monitors with those of a more reliable design before or during the 1981 scheduled refueling outage.
