Yes, nuclear waste can be dealt with adequately, because it is already being dealt with adequately. Nuclear waste is carefully stored by scientists. They have a strong incentive to make sure that there are no mistakes or disasters, because any disaster would spell the end of nuclear energy. Nuclear waste is dealt with adequately with proper protections.
There are ways to deal with nuclear waste that are safe for the environment. However, without proper regulation or facilities, it can be dangerous to store or get rid of the nuclear waste. As long as we can properly regulate these storage facilities and are able to keep the waste safe, it should be adequate enough.
The by-products of nuclear energy are often dealt with inadequately due to poor regulation and lack of appropriate punishments for violations of the regulations. While it is entirely possible that nuclear waste can be contained and stored in a manner sufficient to protect the people and the environment from exposure and contamination it will not be something that is willingly done as it will cost money and cut into the profits made from nuclear energy.
Nuclear waste can not be dealt with adequately. With the increase in technology, we can use another form of energy that is not harmful to the atmosphere. Nuclear energy is dangerous and polluting the environment. It is also very expensive and the mining of the materials needed to create this energy is dangerous as well.
Unfortunately, nuclear waste is difficult to deal with, and the United States has had many issues with waste management in the past. We've shown an inability to properly dispose of such waste, and it has impacted the environment and even people in plenty of negative ways. We can't manage the waste properly.
Nuclear energy is not really clean energy because nuclear waste takes a very long time to degrade and there is no effective means of cleaning, storing or destroying it safely. Because this waste accumulates it is harmful to the environment and creates the possibility of a catastrophic event. There are alternative, renewable and safe means of energy generation, such as wind or hydro power, that are both effective and safe and can be used instead of nuclear energy.
Nuclear reprocessing deals with some of the waste associated with nuclear power, but we have not yet developed a way to recycle nuclear waste completely. At present, we still require a place to hold and contain this waste, which means that there is always some risk of leaks and spills. Perhaps in the future, we will be able to recycle everything associated with nuclear power, but we're not there yet.
