NPP bulk equipment dismantling problems and experience are summarized. “ECOMET-S” JSC is shown as one of the companies which are able to make NPPs industrial sites free from stored bulk equipment with its further utilization. “ECOMET-S” JSC is the Russian Federation sole specialized metallic LLW (MLLW) treatment and utilization facility. Company’s main objectives are waste predisposal volume reduction and treatment for the unrestricted release as a scrap. Leningrad NPP decommissioned main pumps and moisture separators/steam super heaters dismantling results are presented. Prospective fragmentation technologies (diamond and electro-erosive cutting) testing results are described. The electro-erosive cutting machine designed by “ECOMET-S” JSC is presented. The fragmentation technologies implementation plans for nuclear industry are presented too.
