| event text = Planned preventive maintenance on service water piping will remove the service water radiation monitor from service. As a result, this represents a loss of emergency assessment capability under NUREG 1022, Revision 3, since the radiation monitor is used to assess NUE [Notification of Unusual Event] and Alert thresholds. The planned maintenance is expected to last 8 hours. During this time, the site Chemistry Department will perform sampling at this location every 30 minutes. The sampling is documented in a station procedure and allows the ability to detect NUE levels in a timely manner. As a result of sampling, reasonable assurance exists to monitor and detect rising radiation levels in order to protect the health and safety of the public. | | event text = Planned preventive maintenance on service water piping will remove the service water radiation monitor from service.
