2.2.5. Nuclear Wastes MNT cannot treat nuclear wastes and render them harmless directly, for MNT only work with atoms and molecules, not nuclei.  Yet indirectly, by lowering the cost of energy and equipment, MNT can offer us the means for a clean, permanent solution to the untreatable nuclear wastes left over from the nuclear era. Nuclear wastes can be collected, concentrated by specific nanobots. Products of MNT could help with conventional approaches to dealing with nuclear waste, helping to store it in the most stable, reliable forms possible.  Using nanomachines, we could seal them in self-sealing containers and powered by cheap nano-solar energy (10).  These would be more secure than any passive rock or cask.  When MNT has developed cheap, reliable spacecraft, the concentrated nuclear wastes can be transported to the moon and bury them in moon's dead, dry rock by nanobots, or to other planets that still radioactive, or even shoot them directly into the sun. Underground nano-atom smasher powered by cheap solar cells can also be devised to treat nuclear wastes. This is a reverse process of nuclear engineering.  Instead of smashing nonradioactive target and harvesting for radioactive substance, the nanomachine will smash radioactive target and harvest for nonradioactive substance.  The smashing and harvesting process will continue stability is achieved.  Fig. 9 illustrates a few routes for resolving nuclear waste piles that accumulated in the environment and TDBT is at loss on dealing with them.
