Abstract
The present study deals with the characteristics of nuclear material at Light Water Power Reactors put under IAEA safeguards, the current inspection practices at these facilities and the criteria of the relevant Safeguards Implementation Report criteria as minimum requirements for attaining the safeguards goal of the Agency. Also, the implications of the proposed future improvements are considered. The current IAEA inspection activities as well as the detection probabilities and defect levels currently used are also reported. The difficulties encountered in the implementation of the verification measures of the nuclear material for fresh fuel and spent fuel are discussed. The additional inspection activities as required by the proposed future improvements are also discussed including the physical inventory verification and the verification of receipts and shipments. It is concluded that the future up-grading of the present Agency safeguards in Light Water Reactors would necessitate the application of quantitative verification measures on the nuclear material, and the implementation of advanced equipment and techniques.
