One also wishes to choose materials whose primary components and impurities do not result in long-lived radioactive wastes.

Moreover, because a nuclear chain reaction is not involved, the accelerator will produce far less long-lived radioactive wastes.

There is also a need for materials whose primary components and impurities do not result in long-lived radioactive wastes.

Some countries, such as France, specify categories for long-lived low- and intermediate-level waste.

There is always a cost to division, and in the case of nuclear fission it is the long-lived waste radioactive products.

Nuclear reactor accidents remain a possibility and no convincing solution to the problem of long-lived radioactive waste has been proposed.

Furthermore, fusion is clean in that it does not produce long-lived nuclear waste.

The most long-lived radioactive wastes, including spent nuclear fuel, must be contained and isolated from humans and the environment for a very long time.

And like today's reactors, these plants would continue to produce long-lived, highly radioactive waste, for which there is no known, safe method of permanent storage.

Nuclear reactor accidents still occur and there is no convincing solution to the problem of long-lived radioactive waste.
