Abstract: FIELD: chemical engineering and nuclear ecology. SUBSTANCE: invention relates to processing liquid radioactive wastes formed at various-type nuclear power plants installed on transport vessels (nuclear-powered icebreakers, submarines, floating nuclear power stations). Invention consists in system reprocessing of liquid radioactive wastes to remove radionuclides using inorganic sorbent based on transition metal (copper or nickel) ferrocyanide followed by desalting and concentration procedures to separate streams into filtrate with salt content below 0.5 g/cu.dm and saline solution that is further concentrated to yield salts, whereas filtrate is additionally purified by passing through sorbent columns. Exhausted sorbents are then dried and are placed with salts in insulated protective storage tank. Installation contains in-series arranged and interconnected admission vessels; pretreatment unit including sorption treatment column for liquid radioactive wastes placed in protective container provided with upper removable caps and supply and discharge connecting pipes; desalting and concentration units; and exhausted sorbent and salt disposal unit provided with protective storage tank for solid radioactive wastes. The latter unit consists of sorbent drying column unit and transfer container to remove columns out of protective container and their transfer and set up in protective storage tank for solid radioactive wastes.

Abstract: FIELD: direction finding. SUBSTANCE: for determining the bearing to a source of bandwidth noise use is made of receiving nondirectional (or semidirectional) antennas as a receiving antenna system of the direction finder, they are positioned in definite points of the antenna plane so that different pair combinations of the antennas make up a set of bases of direction finders with a uniform spacing of orientation in azimuth in the required range of bearing measurement. The dimensions of bases of the direction finders formed by antenna pairs should are filtered out so as to ensure correlation of radiations picked up by the pair of antennas that are mostly close to the direction to the source. The correlation coefficients of radiations for all pairs of antennas with different orientation in azimuth are computed, and referring to the number of the pair of antennas with the maximum correlation coefficient, determined is the "coarse" estimation of bearing estimation, the delay of the maximum of the mutual time correlation function of radiations picked up by a pair of antennas corresponding to the "coarse" bearing, is computed. The antenna system for realization of this method represents a pair of nondirectional or semi-directional antenna located circumferentially so that pair combinations of these antennas make up a complete set of bases of the direction finders with a uniform spacing of orientation in azimuth equal to π/32 within a range of angles from 0 to π. The ratio of the minimum dimension of the base to the maximum one makes up approximately 0.71. EFFECT: facilitated procedure. 2 cl, 1 dwg, 1 tbl
