Abstract
Safeguards for LWRs are based on annual inventory verifications, supplemented by surveillance cameras to verify that there have been no unreported changes in the inventory. Interim inspections at three-month intervals are primarily to recover camera records. A modification of the surveillance equipment and procedures is suggested whereby surveillance records could be sent by the operator to the IAEA at scheduled times. If the records indicated no spent-fuel shipments, the three- .Tionth interval between inspections could be extended. It is estimated that about threefourths of the interim inspections could thereby be eliminated without compromising present inspection criteria in any way.
