i iil l the analyzer unit caused by excessive condensate in the analyzer air dryer. The I

,,,, g air dryer and.the sample lines to it were dried out, the oxygen analyzer was l

,;3l l recalibrated and the monitor was returned to satisfactory operation.

r LER' ATTACHMENT - RO # l-80-88 Facility: BSEP Unit No. 1 Event Date:

10-25-80 Due to a history of similar moisture problems and other hardware problems involving this type of analyzer, Engineering has. written a plant modifi-cation to replace the monitors and air dryers with more reliable monitors.

The replacement equipment is scheduled to arrive in February 1981, and it

. will be installed during the first available outage following its receipt.
