The approach to the power plant decommissioning optimisation considering the existing or planned national waste management and storage policy

DECOM SLOVAKIA Ltd. is involved in numerous decommissioning studies in the stage of future decommissioning design and performance preparation. Thus, the basic project study for decommissioning of V-1q NPP in Jaslovske Bohunice (reactor type: V-230) and NPP Paks (reactor type: V-213) was elaborated during years 1991-93 in co-operation with further companies (Energoprojekt Prague, EBO-NPP Jaslovske Bohunice, VUJE - Nuclear Power Plant research Institute Trnava, NPP Paks). Recently, the works on V-2 (EBO-NPP), Mochovce NPP and partly on EDU-NPP Dukovany decommissioning project studies are commenced. Several decommissioning option were analysed in performed studies. The estimation of decommissioning materials and wastes volumes and the estimation of pertaining radiation exposure parameters were accomplished as well. The analysis of available and/or future planned technological procedures and equipment sufficiency from the point of view of RAW quality and amounts produced by decommissioning works was elaborated, too. The estimation of corresponding cost was based on selected NPP decommissioning option, determined scope of work and technological procedure determined for individual principal work. (author)
