AA. Introduction

Reprocessing is a technology for separating fissile materials – materials that can 
sustain a chain reaction (6) – from a more complex mixture created in a nuclear 
reactor so that they can be used either in nuclear weapons or in nuclear power 
reactors. It was initially developed during the World War II Manhattan Project for 
obtaining the plutonium-239 to make the bomb that was used on Nagasaki on 
August 9, 1945. This report deals with proposals to use reprocessing as a technology 
to manage nuclear spent fuel from commercial nuclear power reactors and potentially
also to use some of the recovered materials, including plutonium-239, as fuel.

There is only one naturally-occurring fissile material – uranium-235.7 It is only 
about 0.7 percent of natural uranium by weight, which also contains two other 
uranium isotopes: uranium-238 (just under 99.3 percent) and a trace of uranium-234 
(about fifty parts per million). Neither uranium-234 nor uranium-238 is fissile. 
So,in effect, only about 0.7 percent of natural uranium
