design problems, those monitors woro not returned to service within

30 days.

The Main Stack Flow Instrument 2-VA-FIO-33f9 was inoperable for

greater than 30 days due to a Plant Modification (PM 87-166) to

upgrado the instrumentation. Plant Modification 87-166 was

declared operable and the instrument was returned to service on
