Due to a history of problems involving this type of analyzer, a plant modifica-tion has been written to replace the monitors with more reliable monitors. The replacement equipment is scheduled to arrive in February 1981, and it will be in-stalled during the first avai, le outage following its receipt. These analyzers have also been placed in a bt weekly calibration frequency in an effort to main-tain proper operation until the replacement equipment is installed.
