It is also essential in the analysis of unexploded devices or material that have been seized. The basic idea behind nuclear forensics is the same as that behind the FIGURE FOR 1 Lead container and the glass ampoule containing highly enriched 235-uranium seized in Bulgaria in 1999 and analyzed at Lawrence Livermore National Laboratory for foren sic purposes.

An analogous finger print for nuclear reactors is the average energy of the neutron spectrum, from which one can deduce whether the reactor is a thermal light or heavy water reactor or a fast reactor, which will point to whoever designed the reactor. To extract the shape of the neutron flux spectrum for a detonated nuclear device, forensics takes advantage of the very different energy dependencies of nuclear cross sections.

Confidence in the program capability is greatly enhanced by the tight coupling between the fundamental nuclear data community, radiochemists, and the weapons design community. It hopes as well that broadcasting the capabilities of nuclear forensics to identify the source of a nuclear device and its fuel will deter advocates of such unthinkable acts.
