  Info and facts on 'Radioactive waste'   (Site not responding. Last check: 2007-10-21)
Waste can also be generated from the processing of fuel for nuclear reactor ((physics) any of several kinds of apparatus that maintain and control a nuclear reaction for the production of energy or artificial elements) s or nuclear weapon (A weapon of mass destruction whose explosive power derives from a nuclear reaction) s.
This means isolating or diluting the waste so that the rate or concentration of any radionuclides returned to the biosphere (The regions of the surface and atmosphere of the Earth (or other planet) where living organisms exist) is harmless.
While nuclear waste is not as sensitive to disruption as an active nuclear reactor, it is often treated as waste and forgotten.

 Nuclear Waste: Storage and Disposal Methods
Nuclear waste is the type of waste that results from the use and production of nuclear materials.
Also, any form of plutonium may be fashioned into a very potent nuclear weapon; this poses a threat to the safety of humanity (if this nuclear waste were to fall into the wrong hands).
Most of the weapons grade plutonium pits (pits are the nuclear triggers for a hydrogen bomb) from the dismantlement of nuclear weapons are being dry-stored in casks at a facility outside of Amarillo, Texas (Bullen and McCormick 683).

 Waste Management in the Nuclear Fuel Cycle
All parts of the nuclear fuel cycle produce some radioactive waste (radwaste) and the cost of managing and disposing of this is part of the electricity cost, ie it is internalised.
Most nuclear utilities are required by governments to put aside a levy (eg 0.1 cents per kilowatt hour in the USA) to provide for management and disposal of their wastes.
There is an acute awareness in the waste management community of this lack of public confidence; efforts are needed by both implementers and regulators to communicate effectively to decision makers and the public their consensus view that safe disposal can be achieved.
