e LI.R ATTACIDfENT - RO # 1-80-66 Facility: BSEP Unit No. 1 Event Date:

82480 Due to a history of similar moisture problems and other hardware problems in-volving this type of analyzer, Engineering has written a plant modification to replace the monitors 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.
