6.74. IAEA policy for geological disposal facilities is that safeguards requirements will continue even after the waste has been sealed in a geological disposal facility. In the post-closure period, IAEA nuclear safeguards might, in practice, be applied by remote means (e.g. satellite monitoring, aerial photography, microseismic surveillance) although simpler administrative arrangements could also be adequate. “Intrusive methods, which might compromise safety after closure, have to be avoided” [1]. Continuation of the application of safeguards measures could increase confidence in the longevity of administrative controls designed to prevent inadvertent disturbance of the geological disposal facility. In this respect, nuclear safeguards could improve confidence in safety after closure.
