LER ATTAC1DfENT - RO # l-81-23 Facility: BSEP Unit No. 1 Eyent Date:

1-12-81 The failure of the magnetic analy:cr sample cell was a result of corrosion in the analy:cr intake screen that was caused by excessive moisture in the analyzer sample lipe. 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 during a future scheduled

~ outage.
