IAEA interim inventory verification

An inspection activity that does not coincide with the ending date of a material balance period and does not necessarily have to include all nuclear material present in the material balance area. Under INFCIRC 153 safeguards, verification is made for purposes of timely detection or, for example, for re-establishment of the inventory of nuclear material within an area covered by surveillance after a failure of surveillance (INFCIRC 153*).
