A nuclear reactor was being built with certain technical features. These features made it well-suited for producing material that could be used in nuclear weapons. The reactor's capabilities have raised concerns about potential nuclear proliferation.

The International Atomic Energy Agency has been investigating this matter. Its director general has spoken about the reactor's configuration and its potential uses. He noted that the reactor's intentions were not declared and its existence was denied.

Further details about the reactor and the agency's findings are available. The director general's comments were made at a regular meeting of the agency.
