Title: Method of controlling mixed fodder production process
Inventor: LYTKINA L I
IPC: A23N17/00

Granted: 2004-04-20
Abstract: FIELD: mixed fodder production and biotechnology. SUBSTANCE: invention aims at automating mixed fodder production process and comprises grinding and fractioning loose mixed fodder by sieving it through vibrosieve into coarse, middle, and fine fractions. Middle fraction is collected as final product. Fine fraction is granulated being subjected to heat treatment with steam, whereupon hot granules are mixed with loose mixed fodder. This procedure includes temperature and moisture equilibration of mixture before its cooling. Coarse fraction is recycled. During mixed fodder production process, one additionally measures consumption of loose mixed fodder as well as consumption of coarse, middle, and fine fractions and uptake and pressure of steam utilized in heat treatment of fine fraction. Also measured are: granulator drive power, temperature and consumption of hot granules, air uptake on cooling of mixture of hot granules with loose mixed fodder, moisture content and consumption of the mixture prior to be ground, rotation frequency of rolls and distance between mill rolls, amplitude, vibration frequency, and horizontal inclination of vibrosieves. From summary consumption of hot granules and loose mixed fodder to be mixed, heat and moisture exchange time is found. From moisture content of the mixture and its consumption before grinding, distance between mill rolls and their rotation frequency are found, respectively. Granulator drive power is found from consumption of fine fraction, and steam intake corrected taking into account hot granule temperature is found from pressure of steam used in heat treatment of fine fraction. Current ratio of coarse and middle fraction consumptions is continuously monitored. When this ratio deviates from specified values toward higher values, one raises amplitude and rotation frequency of vibrosieves and lowers their horizontal inclination. When above ratio deviates from specified values toward lower values, one lowers amplitude and rotation frequency of vibrosieves and raises their horizontal inclination. EFFECT: improved quality of produce thanks to increased process control precision and reliability. 1 dwg

Granted: 2005-05-27
Abstract: FIELD: nuclear power engineering; handling radioactive wastes and spent nuclear fuel assemblies disposed in floating or coastal stores. 
     SUBSTANCE: proposed method used in particular for dismounting spent defective fuel assemblies disposed in store of floating technical depot includes removal of shielding plug from charging port of swivel slab combined with one of concentrically arranged rows of subchannels in tube plate holding fuel assemblies and detection of all defective fuel assemblies in this row. Upon removal of shielding plug swivel stab is rotated, charging port is aligned with head of box holding defective fuel assembly, and annular drilling is made in tube plate body through this port through depth exceeding weld penetration in tube plate, inner diameter of this drilling being slightly greater than outer diameter of bushing. After that box holding defective fuel assembly is separated from tube plate by blasting through its thickness value followed by its lifting from subchannel together with bushing over height of about 0.8 m from bottom edge of box bushing to top plane of swivel slab. Then auxiliary snap ring is fitted onto cylindrical surface of box, outer diameter of this ring being slightly greater than that of bushing, whereupon box is moved back downward and placed in same subchannel of tube plate. After that charging port of swivel slab is sequentially placed above each box holding defective fuel assembly in this row, and all above-described operations are resumed. Upon completion of all these operations all disrupted boxes are extracted one after the other together with bushings and auxiliary snap rings through charging port. Such method takes minimal time for extracting all defective fuel assemblies from floating technical deport store and ensures essential (by several times) reduction in gamma-ray dose absorbed by personnel and reduced escape of radionuclides into environment due to reduced time taken for auxiliary operations associated with specific process equipment installation on, alignment, and removal from working position.
