By implementation of the Integrated Safeguards Approach, the inspection scheme of JNC-1 site was transferred from the scheduled inspections to RII with short notice. The development of RII was considered under the precondition that it would be conducted without interruption of facility operation. JAEA proposed verification procedures to mitigate the influence on facility operation by the RII. The influence on facility operation by inspection activities of RII was drastically mitigated in comparison with the traditional IIV though implementation of the RII required additional efforts of the operator. This paper reports JAEA's efforts for implementation of RII with short notice in order to mitigate the influence of facility operation by inspection and the impact it has on the facility operation from the operator's standpoint.
