'9 SPECIAL REPORT 96-01 0FFSITE DOSE CALCULATION MANUAL REQUIRED RADIATION MONITOR UNAVAILABLE FOR GREATER THAN SEVEN DAYS This Special Report provides information concerning the reactor building purge i exhaust high range radiation monitoring instrumentation (RM-A1).

On February 18, 1996, Florida Power Corporation's (FPC) Crystal River Unit 3 (CR- ,

3) was in MODE 4 (H0T SHUTDOWN) at 0% power for a refueling outage. At 1851, RM-Al was taken out of service due to failure of the ietector to respond to the check source. At that time, Offsite Dose Calculation Manual (0DCM) table 2-3 Action #29 was entered which requires instrument restoration to service within seven days or submission of a Special Report within the next thirty days. As of March 26, 1996, the instrument has not been restored to service.

A Special Report outlines the actions taken, the cause of the inoperability, and -

the plans and schedule for restoring the system to OPERABLE status.

Troubleshooting efforts indicate the detector failed to exhibit a linear response to a calibration source. A replacement detector will be obtained from stores and bench calibrated. If this unit is not acceptable, parts will be used to make a ,

uorking detector. It is expected the RM-Al will be restored to service prior to i restart from the refueling outage, currently scheduled for April 17, 1996.
