	~~'''~~Duane Arnold Energy Center''' (DAEC) was a nuclear power plant located near Palo, Iowa, in the United States. The facility, named after Duane Arnold, a leader in the Iowa utility industry, was the only nuclear power plant in Iowa. It began commercial operation in 1975 and was officially shut down in August 2020. The plant was primarily operated by NextEra Energy Resources.		== Duane Arnold Energy Center ==

	~~==Overview==~~		[[File:DAEC.jpg\|thumb\|right\|300px\|Duane Arnold Energy Center]]
	~~The~~ Duane Arnold Energy Center was equipped with one General Electric boiling water reactor. With a net generating capacity of approximately 615 megawatts of electricity, it contributed significantly to the energy needs of Iowa and the surrounding region. The plant played a crucial role in providing a stable and reliable source of low-carbon electricity, contributing to the diversification of the energy mix in the area.

	~~==History==~~		The '''Duane Arnold Energy Center''' (DAEC) was a [[nuclear power plant]] located near [[Palo, Iowa]], in the [[United States]]. It was Iowa's only nuclear power facility and played a significant role in the state's energy production until its closure.

	The decommissioning process for nuclear power plants involves the safe removal of radioactive materials, the dismantling of plant structures, and the restoration of the site. For the Duane Arnold Energy Center, this process is expected to take several years and will be conducted under the oversight of the Nuclear Regulatory Commission to ensure that all activities are performed safely and in accordance with regulatory requirements.

	~~==Impact==~~		The Duane Arnold Energy Center was named after [[Duane Arnold]], a former executive of [[Iowa Electric Light and Power Company]]. Construction of the plant began in the late 1960s, and it became operational in 1974. The plant was designed to provide a reliable source of electricity to meet the growing energy demands of the region.

	Throughout its operational life, the Duane Arnold Energy Center was subject to rigorous safety and regulatory oversight by the Nuclear Regulatory Commission. This included regular inspections, reporting, and adherence to strict safety standards designed to protect workers, the public, and the environment.

	~~==Future of the Site==~~		The DAEC was a [[boiling water reactor]] (BWR) type nuclear power plant. This type of reactor uses [[light water]] as both a [[neutron moderator]] and a [[coolant]]. The reactor core heats water, which turns into steam and drives a [[turbine generator]] to produce electricity.

	{{Nuclear-power~~-stub}}~~		The reactor at Duane Arnold had a thermal output of approximately 1,912 [[megawatts]] and an electrical output of around 615 megawatts. The plant was designed to operate with high efficiency and safety standards, incorporating multiple safety systems to prevent and mitigate potential accidents.

			The operation of the Duane Arnold Energy Center had both positive and negative environmental impacts. On the positive side, the plant provided a significant amount of [[carbon-free]] electricity, helping to reduce [[greenhouse gas emissions]] compared to fossil fuel-based power plants.

			However, like all nuclear power plants, DAEC produced [[radioactive waste]] that required careful management and disposal. The plant also had to adhere to strict environmental regulations to minimize its impact on the surrounding ecosystem, particularly the [[Cedar River]], which was used as a source of cooling water.

			== Closure ==

			The Duane Arnold Energy Center was permanently shut down in August 2020. The decision to close the plant was influenced by several factors, including economic considerations, the availability of cheaper energy sources, and the expiration of its [[power purchase agreement]] with local utilities.

			The decommissioning process is expected to take several years, during which the plant will be dismantled, and the site will be restored to a safe condition. The closure of DAEC marked the end of nuclear power generation in Iowa.
