Generate text that refutes this claim: Underground Nuclear Storage is Safe  Underground nuclear waste storage means that nuclear waste is stored at least 300m underground. [I1]  The harm of a leak 300m underground is significantly limited, if the area has been chosen correctly then there should be no water sources nearby to contaminate. If this is the case, then a leak’s harm would be limited to the layers of sediment nearby which would be unaffected by radiation. By comparison a leak outside might lead to animals nearby suffering from contamination. Further nuclear waste might reach water sources should there be a leak above ground, if it is raining heavily when the leak happens for example.  Further, the other options available, such as above ground storage present a potentially greater danger, should something go wrong. This is because it is much easier for nuclear waste to leak radiation into the air. This is problematic because even a hint of radiation may well cause people to panic owing to the damaging and heavily publicised consequences of previous nuclear safety crises. As such, underground storage is safer both directly and indirectly. [1]  As well as this, underground storage also prevents nuclear waste or nuclear radiation from reaching other states and as such, results in greater safety across borders. [2]  Further, storing all nuclear waste underground means that countries can concentrate their research and training efforts on responding to subterranean containment failures. Focus and specialisation of this type is much more likely to avert a serious release of nuclear material from an underground facility than the broad and general approach that will be fostered by diverse and distinct above-ground storage solutions.

[I1] I am not sure how to replace this section. “Leakage” of radioactive material into the air is a minimal danger. The contributor may be referring to the ejection of irradiated dust and other particulates that has occurred when nuclear power stations have suffered explosive containment failures, but this is not comparable to the types of containment failures that might happen in facilities used to store spent nuclear fuel rods and medical waste.  One of the more substantial risks presented by underground storage is release of nuclear material into a water source.
energy house would store nuclear waste underground
Journalist Jeremy Shere describes the problems with most methods of nuclear storage:  "There have been a few other interesting ideas –such as burying nuclear waste beneath the ocean floor. Scientists have also thought about putting waste in really deep holes, burying it in polar ice sheets, and stashing it beneath uninhabited islands. [...] But there are problems with each of these ideas. For example, it would be difficult to monitor nuclear waste under the ocean floor. Waste buried deep in the earth, meanwhile, might contaminate ground water. And as ice sheets continue to melt, it’s hard to say how long nuclear waste would remain buried, or where it would end up if it floated away. Plans to store waste produced in the United States in Yucca Mountain, in Utah, have been put on hold. So for now almost all nuclear waste is kept above ground in special containers at a few hundred different sites around the country.” [1]  The point with underground nuclear storage is that geological conditions are often very different between states and regions; this would often mean that in some states underground nuclear storage would be completely inappropriate because it could leak due to geological changes. Further, underground nuclear storage as mentioned in the first opposition counterargument, actively encourages a state to become reliant on nuclear power.
