Description
Summary:The restoration of the graphite masonry of cell 52-16 in the reactor in the third power-generating unit of the Leningrad nuclear power plant is described. The process reduces to moving graphite blocks and columns from adjacent cells into the damaged cell, from which defective blocks are removed beforehand. The columns are moved in a manner so that the empty cell ends up in the region of the steam-gas exhaust passage through the upper metal structure of the reactor unit. The missing blocks are placed in the reactor through the passage. Organizational-technical and radiation questions concerning the work performed are described. 6 figures.[PUBLICATION ABSTRACT]
