| event text = Both Discharge Canal Radiation Monitor Sample Pumps will be removed from service to facilitate planned maintenance activities. This represents a loss of emergency assessment capability under NUREG-1022 Revision 3 since the Discharge Canal Radiation Monitors are used to assess NUE [Notification of Unusual Event] and Alert thresholds. The Sample Pumps are expected to be unavailable for approximately two hours. During this time, Chemistry will be obtaining samples every 2 hours. As a result of the sampling, reasonable assurance exists that rising radiation levels will be able to be detected and monitored in order to protect the health and safety of the public. | | event text = Both Discharge Canal Radiation Monitor Sample Pumps will be removed from service to facilitate planned maintenance activities.
