Such a facility for spent fuel from the existing four blocks of Hungaryʼs Paks nuclear power plant would cost approximately HUF 1.671 trillion, the paper calculated based on data from the Hungarian Academy of Scienceʼs Lévai András Energetics Foundation and Hungaryʼs state-owned company for managing radioactive waste RHK. The academyʼs foundation estimated the cost of additional capacity for spent fuel from a planned upgrade at the Paks plant to be HUF 1.150 trillion.
