No, lasers would not cause nuclear changes, they would only melt or vaporise material which is not what is wanted. The nuclear properties of the waste would remain the same.
its a method use in nuclear waste management where the waste is concentrated and then isolated. this method also use for non nuclear waste management.
High level nuclear waste is created in two main ways: - Nuclear energy reactors during normal operations generate radioactivity which affects metals and water in the plant; also used-up fuel is left over after being used for reaction. - Nuclear weapons programs use nuclear reactors to create plutonium with a lot of radioactive byproducts. The leftover materials and just about everything that comes near the weapons material becomes nuclear waste. Low level nuclear waste is created in many ways, some of them not so obvious. - Hospitals use radiation in cancer treatment, nuclear imaging, etc. - Homes use radioactive materials in smoke detectors. - Naturally occurring radiation can effectively be concentrated in air and water filters, such as radon filters for well water. - Naturally occurring radiation can be concentrated in coal ash by coal-fired power plants, often along with dangerous pollutants like mercury. There are many other sources of low level nuclear waste and many tons of it must be safely disposed.
High level radioactive waste would have no potential for producing a nuclear explosion, so your question is puzzling. Perhaps you mean production of a dirty bomb, which terrorists might use to contaminate an area by spreading radioactive material around using a conventional explosive. That is obviously not justified unless you are a terrorist.Plutonium can be extracted from spent uranium fuel and used in nuclear weapons, but I would not describe it as high level radioactive waste, plutonium is only mildly radioactive.In fact I think at present in the US and in Russia, the stockpile of nuclear weapons is being reduced and some of the fissile material is going into civil nuclear reactor fuel.
There are three main categories of nuclear waste:High Level Waste, including waste fuel and similar materialsIntermediate Level Waste, such as materials from reactor decommissioning, sludge, and so on, that require shielding. This category is not in use in the United States. In the United States there is an intermediate level termed Transuranic Waste, which consists of materials that contain transuranic elements due to contamination, and so need shielding.Low Level Waste, including materials contaminated with radioactive materials with short half lives, such as clothing, paper, filters, tools, and so on, that can be stored for a relatively short time and requires little, if any, shielding aside from short term burial
There are 2 primary hazards of nuclear waste. The first is a simple one- a chemical hazard. Some wastes are poisonous, just like their non-radioactive cousins. Poisons can damage different organs of the body, and make you sick- or in high enough concentrations, kill you. The second hazard is the ionizing radiation given off by the waste. Depending on the waste, this may be very low level that is only dangerous if ingested into the body, or high enough to damage the whole body. Known as radiation sickness, an overexposure to hard (ionizing) radiation can cause failures of organ systems, sickness or death, and can cause cancer. The degree of hazard depends on the form of the waste, and how "hot" it is. A solid piece of concrete or steel that is mildly radioactive can be placed in storage with little danger of it being carried into the environment. A water soluble substance like iodine is at a greater hazard of leaching into the environment, and being absorbed by your body.
No, but experiments with lasers to produce nuclear fusionare being conducted, and this technique may be used sometime in the future in a fusion nuclear reactor.
Because you can reuse 17% of nuclear waste and use it as if it was new.

"Waste" has never any use. Nuclear waste is stored in facilities in the hope that someday, someone will figure out how to deal with it.
Three problems associated with nuclear waste
Nuclear Power plants use refined uranium or plutonium. Both of these elements are extremely radioactive and unstable. In order to control the explosive reaction (google atomic bombs), they use control rods in the process to slow the reaction rate, keeping it under control. These control rods, along with all clothing, tools, and other items taken into the reaction chamber become nuclear waste. This is one cause for debate against nuclear energy as there are no means of destroying/disposing of these waste products. But that is a different debate.
Lasers emit radiation and are used in many medical treatments such as cutting, cauterizing, shrinking and even destroying. Their purposes can be endless and used to help treat many people in medical need.
It just has to be stored for centuries
Radioactive waste
A major drawback to the use of nuclear power is that it produces radioactive waste. This waste can pollute water sources and kill organisms.

Nuclear power creates toxic waste that must be stored forever
