Description
Three electrochemical, remotely operated decontamination equipments were developed for the Paks NPP. The first equipment was constructed for the decontamination of the main circulating pump case, the second equipment for the collectors of the steam generator and the third equipment for the main gate valve case of the primary circuit. All the equipments use movable cathodes. The main circulating pump case was decontaminated eight times. The electrolyte contained sulfuric, oxalic and phosphoric acid. The decontamination factor of the plant 10-500. The duration of the process was 8-12 hours. The collective dose for the staff (3-4 workers) was about 2-3 mSv. Only 100-200l of radioactive effluents were produced
