Although the nitration step can be separate from the voloxidation step, the nitration step can include contacting the solid oxidation product 30, or the spent nuclear fuel 26 in the second zone 16 of the voloxidizer 12, with a nitration gas comprising nitrogen dioxide for {HEAD ~ a period} sufficient to produce {TAIL ~ a nitration product}
