This is the place where I always get very circumspect and quiet. And I will tell you why. So they are unwilling to talk about solutions to the waste problem and are accused of brinksmanship. It was the people who made this material without knowing what to do with the lethal waste. When Congress asked the Department of Energy to write a report on how they are going to handle the next generation of waste, if they actually build a next generation of reactors, the DOE came up with a couple of scenarios.
Some people think it is a good idea because it allegedly makes waste that is less long-lived.
Plus it makes an even greater low-level waste problem. It just doesn't do the job. It only effects two percent of the fuel waste. Right now it is an institutional classification system. This means classifying waste on the basis of its source not it's danger as the names imply.
