| event text = A planned maintenance evolution at the Duane Arnold Energy Center (DAEC) has removed the emergency power supply to the TSC from service as of 0900 EDT. If a loss of the normal power supply to the TSC were to occur during this period, the TSC would be rendered non-functional. The repair to the power supply is expected to last 6 hours. If an emergency is declared requiring TSC activation during this period, the TSC will be staffed and activated using existing emergency planning procedures. Maintenance will be expedited to restore the emergency power supply to service. This notification is being made in accordance with 10 CFR 50.72(b)(3)(xiii) due to the loss of an Emergency Response Facility (ERF). An update will be provided once the TSC emergency power supply has been restored to normal operation. | | event text = A planned maintenance evolution at the Duane Arnold Energy Center (DAEC) has removed the emergency power supply to the TSC from service as of 0900 EDT.
