Enclosure to ENO Letter 2.07.051 Special Report Cause of Inoperability The Main Stack high range radiation monitor became inoperable on May 5, 2007, while shut down for the 2007 refueling outage.

The monitor was inoperable because it was discovered to have failed downscale. The cause of this failure was later attributed to a power interruption to the monitor.

Actions Taken A work request was initiated to correct this condition. The monitor was re-energized and post work testing was completed on May 15, 2007 and the monitor was declared operable.

Plans and Schedule to Restore the Instrument to Operable Status The Main Stack high range radiation monitor was restored to operable status on May 15, 2007.
