The project involves dismantling the underground system (called Waste A and B) to collect the radioactive effluents of the OPEC-1 plant. The system included the collection tanks and their related plant building.
During the plant's operation, the tanks collected the radioactive liquids resulting from the hot cells - namely, environments specifically designed for the safe manipulation of irradiated nuclear fuel.
In the 2014-2015 period, the operators dismantled the plant building of the underground system; following this activity, the removed pipes, tanks, and residual liquid were sent to Nucleco for treatment and final conditioning.
Then, the operators analysed the remaining premises through radiological mapping before launching the second dismantling phase. The latter involves the decontamination and controlled demolition of underground civil works, the "release" of the site to dismantle the containment premise, and the final reclamation of the area.
In 2021, Nucleco executive project was approved. Working site operations will commence after receiving the approval of the Operational Plan on behalf of ISIN (National Inspectorate for Nuclear Safety and Radiation Protection).
