Entergy will also move a set yearly number of spent fuel rods from their dangerous storage pools to dry cask storage on site — a much safer solution for this radioactive material.
No containment structures exist over the spent fuel pools; the pools are vulnerable to a loss - of - coolant scenario; mock attack drills reveal accessibility to and vulnerability of spent fuel buildings; and two of the spent fuel pools at Indian Point have been leaking radioactive materials.
Although some have argued that current methods of managing nuclear waste present problems, I would affirm that safe, effective management of used fuel and other radioactive material have been consistently demonstrated over several decades.
This component is only mildly radioactive and, if separated from the fission products and the rest of the material in the spent fuel, could readily be stored safely for future use in lightly protected facilities.
At Yucca, spent fuel housed in steel canisters would be sealed within tunnels above the water table, in a manner meant to minimize corrosion and possible leakage of radioactive material, even over geologically long periods.
The fire in the spent fuel store of reactor unit 4 has probably released the worst of the radioactive materials so far.
Highly packed spent fuel pools at the Japanese facility have caught fire, lost coolant, and released unknown quantities of radioactive material, underscoring the need to remove as much fuel from overcrowded pools as possible.
The pools — water - filled basins that store and cool used radioactive fuel rods — are so densely packed with nuclear waste that a fire could release enough radioactive material to contaminate an area twice the size of New Jersey.
A report to Congress in 2006 by a National Research Council panel investigating terrorist threats to spent fuel storage concluded that «under some conditions,» if a pool were partially or completely drained, that «could lead to a propagating zirconium cladding fire and the release of large quantities of radioactive materials to the environment.»
The difference between this accident and Chernobyl, they say, is that at Chernobyl a huge fire released large amounts of many radioactive materials, including fuel particles, in smoke.
In 2010, the Obama administration abandoned a 2 - decade effort to bury much of the high level waste — spent fuel rods from commercial reactors and radioactive material from nuclear bomb manufacturing — inside Yucca Mountain in the Nevada desert (although Congress has ordered parts of that process to keep moving).

That material includes everything from buildings and railways, to tanks of diesel fuel, radioactive coolant, and likely an unknown amount of toxic polychlorinated biphenyls (PCBs).
Such boreholes could not house most of the country's waste, like fuel rods from nuclear power plants, but could have potential for smaller, long - lived radioactive materials.
