20. Concerning the alleged work to design and build an EBW detonator and a suitable detonator
firing unit, Iran acknowledged that it had conducted simultaneous testing with two to three EBW
detonators with a time precision of about one microsecond. Iran said, however, that this was intended
for civil and conventional military applications. Iran further stated, inter alia, that there was no
evidence in the documents presented to it to link them to Iran.
A second aspect concerns the development and testing of high voltage detonator firing.
equipment and exploding bridgewire (EBW) detonators including, inter alia, the simultaneous firing of
multiple EBW detonators; an underground testing arrangement (GOV/2008/4, para. 39); and the
testing of at least one full scale hemispherical, converging, explosively driven shock system that could
be applicable to an implosion-type nuclear device. A third aspect of the studies concerns development
work alleged to have been performed to redesign the inner cone of the Shahab-3 missile re-entry
vehicle to accommodate a nuclear warhead
