Joint Intelligence Committee (JIC) Assessments: 1999 2001

17. Since 1999 the JIC has monitored Iraq's attempts to reconstitute its nuclear

weapons programme. In mid 2001 the JIC assessed that Iraq had continued its

nuclear research after 1998. The JIC drew attention to intelligence that Iraq had

recalled its nuclear scientists to the programme in 1998. Since 1998 Iraq had

been trying to procure items that could be for use in the construction of

centrifuges for the enrichment of uranium.

Iraqi nuclear weapons expertise

18. Paragraphs 5 and 6 of Chapter 2 describe the Iraqi nuclear weapons programme

prior to the Gulf War. It is clear from IAEA inspections and Iraq's own

declarations that by 1991 considerable progress had been made in both

developing methods to produce fissile material and in weapons design. The

IAEA dismantled the physical infrastructure of the Iraqi nuclear weapons

Elements of a nuclear weapons programme: nuclear fission weapon

A typical nuclear fission weapon consists of:

G

fissile material for the core which gives out huge amounts of explosive

energy from nuclear reactions when made  super critical  through

extreme compression. Fissile material is usually either highly enriched

uranium (HEU) or weapons grade plutonium:

HEU can be made in gas centrifuges (see separate box on p25);

plutonium is made by reprocessing fuel from a nuclear reactor;

G

explosives which are needed to compress the nuclear core. These

explosives also require a complex arrangement of detonators, explosive

charges to produce an even and rapid compression of the core;

G

sophisticated electronics to fire the explosives;

G

a neutron initiator to provide initial burst of neutrons to start the nuclear

reactions.
