LER ATTAC1! MENT - RO #2-80-73 l

Facility $ BSEP. Unit No. 2 Event Date: 9-27-80 Due to a history of similar m'isture 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 j

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