The controversy over Iran's nuclear programs centers in particular on Iran's failure to declare sensitive enrichment and reprocessing activities to the IAEA.

It follows a decision last month by the administration to sit at the same negotiating table with Iran - if Iran fully suspended its uranium enrichment and reprocessing activities.

Pakistan has repeatedly refused calls for international inspections of its enrichment and reprocessing activities.

In 2003, the International Atomic Energy Agency (IAEA) first reported that Iran had not declared sensitive enrichment and reprocessing activities.

In 1974 Eurochemics stopped its reprocessing activities.

Immediate needs are scheduled to be met by buying in spent fuel reprocessed in the UK and France, as well as Japan's own reprocessing activities.

On 31 July, the Security Council passed a resolution demanding that Iran stop "all enrichment-related and reprocessing activities".

It would order Iran to cease all uranium enrichment and reprocessing activities, including research and development and the construction of a heavy-water reactor.

At the heart of this initiative was a proposal that Iran should restore confidence by suspending all uranium enrichment related and reprocessing activities while we discussed mutually acceptable, long-term arrangements.

If Teheran renounces uranium enrichment activities, Iran must completely and verifiably suspend all of its uranium enrichment and reprocessing activities.
