By now it is clear to everyone that, regardless of the future, or even the present, of nuclear power, the nuclear waste problem must be solved. And it is unconscionable to delay.
For one thing, the military waste -- larger in volume if not radioactive content than any other such waste until the end of this century -- will continue to exist and demands some solution; for another, there is already in existence a considerable pile of nuclear waste which implies a similar demand for solution.
Although it may be a bit early to tell, there does not seem to be any insurmountable technical problem associated with separating nuclear waste from the biosphere for long periods of time. Problems abound, but all seem likely to succumb to vigorous attack by the scientific and technological communities. It is true, however, that the more closely the scientific community looks at the issue, the more problems arise. Bedded salt repositories,for 25 years the most efficacious disposal sites, according to conventional wisdom, were discovered upon close examination to have as many potential problems as the alternatives. All will be carefully considered and tested in the next few years; a testimony, at long last, to the value of diversity. We have not seen the end of technical controversies on this issue by a long shot.
However, the nation's nuclear-waste problem is even more importantly a political problem, exacerbated by the fact that it received relatively little intellectual attention, scientific or otherwise, for 25 years.
For that unforgivably long time it was treated as a purely engineering problem, with those involved in it showing no understanding of the particular political sensitivity of the issue. Indeed, politicians were, almost without exception, insensitive to the nuclear waste issue during this period.
In retrospect, it is hard to believe we ignored the fact that people demand more from something that is going to be around for a thousand years than from something that is going to be around for just 30. And people really do care about one another. They do not want to poison their neighbors' wells or do anything that would harm their grandchildren. The lack of a demonstrated solution to the problem of nuclear waste was viewed not as an example of technological inattention -- which was only partially the reason in any case -- but rather as a result of the human inappropriateness of any solution developed to date. It did not take much for some people to come to the conclusion that no appropriate solution was possible.
