VIENNA — With time for negotiations running short, the U.S and Iran are discussing a compromise that would let Iran keep much of its uranium-enriching technology but reduce its potential to make nuclear weapons, two diplomats tell The Associated Press.
Such a compromise could break the decade-long deadlock on attempts to limit Iranian activities that could be used to make such arms: Tehran refuses to meet U.S.-led demands for deep cuts in the number of centrifuges it uses to enrich uranium, a process that can create material with applications from chemotherapy to the core of an atomic bomb.
Experts warn that any reduction in centrifuge efficiency is reversible more quickly than a straight decrease in the number of machines, an argument that could be seized upon by powerful critics of the talks in the U.S. Congress.
The diplomats are familiar with the talks but spoke only on condition of anonymity because they are not authorized to discuss them. Ahead of a new round of negotiations this week, they said there is no guarantee that the proposal can be finessed into an agreement.
According to the diplomats, the proposal could leave running most of the nearly 10,000 centrifuges Iran is operating but reconfigure them to reduce the amount of enriched uranium they produce.
One of the diplomats said the deal could include other limitations to ensure that Tehran’s program is kept in check.
For one, Iran would be allowed to store only a specific amount of uranium gas, which is fed into centrifuges for enrichment. The amount of gas would depend on the number of centrifuges it keeps.
Second, Iran would commit to shipping out most of the enriched uranium it produces, leaving it without enough to make a bomb. Iran denies any interest in nuclear weapons and says its program is for peaceful uses such as nuclear power and medical technology.
