摘要

Recently, a low-temperature recyclable decontamination medium was developed and patented at Department of Nuclear Chemistry, FNSPE, CTU in Prague for the purposes of decontamination for decommissioning. Due to the presence of silver ions used as a catalyst in the original technology, the medium is not suitable for use in operational decontamination. Current research focuses on modifications in its chemistry to make it applicable for operational decontamination of primary circuit components in specific conditions of Czech nuclear power plants. Summary of the first part of the work aimed at finding a suitable replacement for silver ions. Testing of its effectiveness on model substrates is described in this paper.

This work was presented at APSORC25 conference (14–19 Sep 2025) in the track R3 Actinide Chemistry and Nuclear Chemistry.
