At alternative to reuse of plutonium is disposal in a GDF and it is likely that some of the plutonium inventory will require disposal as it will not be suitable for reuse. We are interested in technologies and techniques that would enable plutonium disposal in the GDF. This includes both treatment options and disposal package design.
Existing potential options include Disposal MOX and Hot Isostatic Pressing (HIP) to produce a ceramic wasteform. Similarly to reuse, we are interested in any constraints that would limited how much of the plutonium inventory could be disposed of or how quickly it could be disposed.

Plutonium dioxide is a very dynamic material. Radioactive decay damages the lattice and also forms other elements in the material. Helium, an inert gas, may be localised or trapped in the lattice, or maybe released. Uran...

The safe disposal of radioactive waste is a problem that must be solved . First, there is the existing legacy of waste in the UK (about 3.4 million cubicmetres of which 1,100 cubic metres is high level waste - not counti...
