Joseph M. Farley Nuclear Plant, Unit 1 Special Report 2008-002-00, Inoperable Radiation Monitor R-60B Enclosure Special Report 2008-002-00

Joseph M. Farley Nuclear Plant, Unit 1 Special Report 2008-002-00, Inoperable Radiation Monitor R-60B Enclosure Special Report 2008-002-00 This Special Report is being submitted due to the Unit 1 radiation monitor R-60B (Main Steam Relief and Atmospheric Steam Dump Discharge) not being restored to operable status within the time required by Technical Requirements Manual (TRM) TR 13.3.4. TR 13.3.4 requires the monitor to be restored to operable status within 7 days or submit a Special Report within the next 14 days following

the event.

At 0400 on April 30, 2008 radiation monitor R-60B was declared inoperable due to a failed indication on the control panel. A mandatory Limiting Condition for Operation (LCO) was written requiring restoration to operable status by May 7, 2008 at 0400 hours0.00463 days <br />0.111 hours <br />6.613757e-4 weeks <br />1.522e-4 months <br /> and a work order was generated to repair R-60B.

Maintenance troubleshooting isolated the problem to the detector. Due to the detector's location on the main steam valve room roof in close proximity to steam generator safety relief valve exhaust piping, repair of the monitor is a personnel safety concern should any relief valve lift during the repair effort. Therefore, repair of the monitor should be performed only under cold shutdown conditions to ensure personnel safety. R-60B is scheduled to be repaired during the next refueling outage currently scheduled for spring 2009 or at the next outage of sufficient duration when the plant will be in cold shutdown. TRM action requirements are being met for radiation monitor R-60B.
