Title | Loss of Assessment Capability - Radiation Monitors Inoperable for Pre-Planned Maintenance |
Event Description | This is a non-emergency notification. At approximately 08:40 EST on January 14, 2013, radiation monitor RM-01TV-3547-1, Waste Processing Building Vent Stack 5A Wide Range Gas Monitor (WRGM) will be declared inoperable for pre-planned maintenance. MST-I0377, WPB Stack 5A Accident Monitor Channel Calibration will be performed. The maintenance activity is expected to complete January 15, 2013.
This radiation monitor is necessary for accident assessment and is credited for Emergency Action Level (EAL) classification in the Harris Nuclear Plant Emergency Plan. Inability to classify an EAL due to an out of service monitor is considered a loss of accident assessment capability and is reportable per 10 CFR 50.72(b)(3)(xiii) as described in NUREG-1022, Rev. 2. This condition does not affect the health of safety of the public or the operation of the facility. The NRC Resident Inspectors have been notified. |
