Nuclear waste dumps

[Targan]

An article I read today has got me thinking.

Aside from whether all of the locations where radioactive waste was stored before the war remain in governmental control during and after the Twilight War, could the maintenance that some of these facilities require be kept up?

For instance, what would happen if absolutely nothing was being done to prevent leakage at the Hanford Nuclear Reservation? How much groundwater could that contaminate? What would the consequences of uncontrolled leakage be and over what timescales?

What if some group like New America decided that it wanted to build a bunch of dirty bombs? What sort of priority would MilGov or CivGov place on placing such facilities back under it's control?
