Here's a ranking of how radioactive waste storage shakes out, from waste-free states to states with a lot of radioactive residue.
Among the waste-free: Nevada. Yes, the Nevada Test Site was established in 1951 to test nuclear weapons. But the state currently has no spent nuclear fuel.
Other states with zero waste: North Dakota, South Dakota, Wyoming, Utah, Oklahoma, Indiana, Kentucky, West Virginia, Delaware, Rhode Island, Alaska, Hawaii and Montana.
Data was gathered from the Nuclear Energy Institute.
New Mexico doesn't have any spent fuel rods, but it is home to the Waste Isolation Pilot Plant (WIPP) which hosts 4.9 metric tons of plutonium deep in a salt mine.
Residents who lived downwind of the former Rocky Flats Nuclear Weapons Plant are no strangers to the effects of improperly handled nuclear waste. The health survey shown here, conducted by MSU Denver, tracks unusual illnesses in areas exposed to the after-effects of manufacturing at the Rocky Flats plant.
At the Argonne Nuclear Labs Western Plant, scientists research methods for storing nuclear waste.
The cooling tower at the Trojan Nuclear Power Plant was destroyed in a controlled demolition when the plant was decommissioned in 2006. But 34 steel and concrete storage casks filled with radioactive materials remain.
The Duane Arnold Energy Center is Iowa's only nuclear plant. In its last safety inspection by the Nuclear Regulatory Commission, the plant performed as well as any facility can.
This photo shows what remains of the old Maine Yankee Nuclear Power Plant in Wiscasset, Maine. Those cylinders are dry storage casks. Research is still being done surrounding the long-term integrity of this storage method.
This photo shows a 1979 protest over the Seabrook Station. In 2013, the NRC and researchers from Stanford University both expressed concern that Seabrook is vulnerable to earthquakes and flooding from rising sea levels.
Entergy Vermont Yankee nuclear power plant was decommissioned on December 29, 2014, but these casks remain.
The NRC recently designated the reactor at Pilgrim Nuclear Power Station in Plymouth, Massachusetts, as one of the nation's three least-safe reactors. There are also more than 3,000 spent fuel assemblies currently cooling in the storage pool.
This is the sign outside of the Hanford Nuclear Reservation in Washington, where a tunnel storing contaminated materials recently collapsed and forced the evacuation of the facility.
The water in Coffey County Lake is heated inside the plant. The lake water acts as a coolant for the Wolf Creek Nuclear Power Plant in Kansas.
No, this isn't an ancient Egyptian tomb: This is the resting place of 1.48 million cubic yards of toxic waste from what was the largest explosive factory in the United States.
Instead of moving the radioactive factory somewhere else, the government sealed the groundwater system and then buried the demolished buildings with 45 acres of stone, concrete and clay.
The Missouri River flooded in 2011 and surrounded most of the Fort Calhoun plant. Water was kept away from vital buildings long enough for the flooding to subside. Though the public was never in danger, a small fire prompted a partial evacuation.
Mississippi has its own stock of spent nuclear fuel rods stored near reactors like this one at the Grand Gulf Nuclear Generating Station which, at 4,408 thermal megawatts, is the most powerful reactor in the United States.
Mississippi is also on the transit route for low-level radioactive waste to the WIPP in New Mexico.
Davis-Besse Nuclear Power Station near Toledo, Ohio has experienced 11 safety incidents, including one in 2002, when a football-sized hole was discovered in the reactor head. That corrosion put the plant on the brink of nuclear meltdown.
No radiation escaped, but the NRC fined owner FirstEnergy Corp. more than $5 million, and the U.S. Department of Justice fined it $28 million.
Dry cask storage of spent nuclear fuel rods sees sustained opposition from some residents of neighboring Prairie Island Indian Community Reservation.
This is the Waterford 3 plant. In 2011, the NRC deemed it a high risk for flooding.
The Department of Energy and the NRC have considered Louisiana's Vacherie salt dome as a potential long-term storage facility for high-level waste. But the state has banned any study or speculation of a salt-dome solution.
Minnesota's National Guard trains for disasters like nuclear contamination caused by tornadoes. The La Crosse Boiling Water Reactor is protected by thick concrete walls, but keeping enough power to cool the reactor could prove a challenge after a big storm.
The NRC has rated the Arkansas Nuclear One plant as the worst in the country for safety standards. In 2013, one worker was killed and eight more were injured in a botched evacuation.
Environmental groups such as the Sierra Club oppose the expansion of Calvert Cliffs Nuclear Power Plant, citing concerns over waste storage as well as increased risks of accidents or terrorist attacks.
Oak Ridge, Tennessee was once a central part of America's Manhattan Project effort to build a nuclear bomb. Now Oak Ridge stores spent nuclear fuel from around the world. Germany and France have both contracted the city to store low-level waste.
This aerial photo of the now-decommissioned Connecticut Yankee plant shows dry casks filled with low- and high-level waste from sections of the disassembled reactor.
In 2003, the National Guard was dispatched to the Palo Verde facility in Arizona in response to a specific terrorist threat against the power plant.
This photo shows inspectors from the NRC touring the Comanche Peak Nuclear Power Plant in Somervell County, Texas.
A 2011 earthquake in Virginia caused the 117-ton spent fuel casks at North Anna nuclear plant to move a few inches, but the plant weathered the event with no serious damage.
This sign tells residents of Lower Alloways Township, New Jersey what to do if they hear the sirens from the Salem Nuclear Power Plant or Hope Creek Nuclear Generating Station. Tens of thousands of people live within the plume exposure pathways of these two plants.
This plant in Wayensboro, Georgia was supposed to signal a new wave of nuclear power in the United States. However, construction delays and hiccups with shipping have bankrupted Westinghouse.
These power plants on the banks of Lake Erie are named after Enrico Fermi, the Italian physicist and inventor of the nuclear reactor.
Florida Power & Light wants to store spent fuel rods under Biscayne Bay near the Turkey Point Nuclear Power Plant. The bay is home to fragile populations of endangered species, including this crocodile, and also provides drinking water to the people of southern Florida.
The red arrow points to the location of dry storage casks at the decommissioned San Onofre power plant. The casks, filled with 3.6 million pounds of radioactive waste, are perched about 100 feet from the ocean in an area prone to earthquakes.
According to 2010 US Census data, the population in the plume exposure radius of this power plant has more than doubled since 2000.
These benign-looking blue and white signs point the way to safety in the event of an emergency at Browns Ferry Nuclear Power Plant near Athens, Alabama.
Renewable energy advocates protest Gov. Andrew Cuomo's nuclear bailout plan on May 17, 2017. The taxpayer cost is a matter of contention, as is the danger of having an ever-growing store of nuclear waste onsite at New York's four nuclear power generating stations.
The Department of Energy currently owns the Savannah River Site, a nuclear reservation where radioactive materials were once refined for use in bombs. 84-year-old Byron Vaigneur of Jackson, South Carolina, worked at there for 33 years. He received $350,000 from the federal government for chronic diseases he contracted from working at the site.
Abrianna Nissley, 6 is seen swinging at sunset with a view of the Three Mile Island nuclear power plant from her family farm. In 1979, Three Mile Island was the site of the worst commercial nuclear accident in U.S. history.
About 1,000 tons of highly radioactive waste is reportedly stored in a containment pool on the Zion Nuclear Power Station property, and there's no plan for how to deal with it permanently.
General Electric owns the country's only high-level nuclear waste storage site, called the Morris Operation, in Grundy County, Illinois.
