Hurricane Helene Floods Closed Duke Nuclear Plant in Florida
(Bloomberg) -- Floodwaters from Hurricane Helene have swamped a retired Duke Energy Corp. nuclear power plant, according to a filing with the Florida Department of Environmental Protection, though an escape of contaminated fuel appears unlikely.

The Crystal River plant, which has been shuttered since 2013, experienced a storm surge of as much as 12 feet, according to the filing, which was posted online.
“The whole site was flooded, including buildings, sumps, and lift stations. Industrial Wastewater Pond #5 was observed overflowing to the ground due to the surge,” according to the report, which was filed Friday, the day after Helene roared ashore.
“We are still in the process of obtaining access and assessing the damage, but due to the nature of this event we anticipate difficulty with estimating the total discharge amount of wastewater, and impacts are unknown at this time,” the report said.
The used nuclear fuel at the site remains secure, Duke Energy said in a statement Sunday. “All radioactive material has been segmented and permanently packaged in shielded containers impervious to the effects of extreme weather,” the company said.
The facility, just south of Cedar Key, is still in the process of being dismantled. It’s likely that the spent fuel, which is kept onsite in dry storage, is safe, Edwin Lyman, a nuclear specialist with the Union of Concerned Scientists, said in an email before Duke Energy commented.
“There is probably still quite a bit of low-level radioactive waste awaiting shipment, and it’s likely the site wastewater has low levels of radioactive contamination,” Lyman said in an email. “Although anything is possible, based on the Fukushima experience, if the storage area were immersed in water for a short period of time, there is unlikely to be significant damage or leakage from the canisters.”
The site also flooded in 2023 after Hurricane Idalia made landfall, according to a report in Newsweek, that said spent fuel was scheduled to remain on site until 2037.
