Abstract

The work is designed for the establishment of experimental techniques for replicating of highly-active neutron irradiated samples in SUSEN hot-cells. Using the most sensitive devices for dimensions and defects measurements of irradiated materials is limited due to the negative effect on their operation lifetime and accuracy. Therefore, new replication techniques are needed for the long time operation of the hot cells and its equipment which are sensitive to gamma radiation. The replicas of irradiated material, that are made using manipulators inside the hot-cell, are made of the polymers that are not activated during the operation, so that they can be easily used for the standard measurement procedures. This work describes 3D dimensions measurement and reconstruction of the irradiated materials and evolution of the replication methodology.
