Improving NPT safeguards. Particularly at the natural uranium starting point

摘要

According to the Non Proliferation Treaty (NPT) all nuclear material is subject to safeguards, but according to INFCIRC/153 the full range of safeguards is only applied beyond the 'starting point of safeguards', that is: The point at which nuclear material has reached a composition and purity suitable for fuel fabrication or enrichment. This paper addresses the two questions: (a) is the starting point adequately defined, and (b) what mesures could be applied to nuclear material before the starting point. Those questions have been asked before, some of the answers in this paper are new. (orig.). (Atomindex citation 28:009355)
