NextEra Energy Duane Arnold has an outstanding record of safe operations. The facility is designed to withstand earthquakes and other natural events more severe than ever recorded in the region. The plant is elevated 20 feet above the river level, which protects against flooding.
In addition, many layers of security protect the plant. The Nuclear Regulatory Commission, federal and local law enforcement, as well as the Duane Arnold Energy Center’s own expert security team, are always on alert to ensure that plant facilities are protected and secure.
As part of our commitment to safety, our outdoor warning sirens are tested regularly. Siren tests are conducted by local emergency management officials on the first Wednesday of each month at about 8:45 a.m. and last two minutes or less.
