SYSTEM OF CERAMIC INSULATORS CONTROL


System is a hardware-controlled complex designed for automated control of the appearance and end surfaces of nuclear ceramic fuel tablets.

  •     Parameters controlled tablets:
    • Diameter...............................................from 7.54 to 7.8 mm
    • Length................................................. from 9 to 12 mm
  •     The probability of detecting deviations of appearance of tablets, not less.....................0,95
  •     The probability of culling suitable tablets, not more than ............................................2%
  •     Types of detected deviations:
    • chips, spallings, prints on the face with, or without entry on the cylindrical surface, and with, or without entry on the axial hole, the area of one defect, not less..............5 mm2;
    • lack of a central hole;
    • depth of identified holes is not defined.
  •     The total area of chips or prints of a punch on each face, not more than.................20%
  •     Productivity of the unit, not more than .......................................................... 6 tablets per second.
  •     Power supply of system is performed from AC line voltage (220 +20-33 )V, frequency (501) Hz.
  •     Power consumption.............................................................................................1000 watts.
  •     Overall dimensions, not more:
    • optics-mechanical block .1156.01............................................910 x 430 x 265 mm
    • system of information processing and control .1156.45 600 x 600 x 1600 mm
  •     Weight, not more:
    • optics-mechanical block .1156.01..........................................................27 kg;
    • system of information processing and control .1156.45............................100 kg.
  •     Average service life, not less..............................................................................5 years.


    The operating principle of the system is based on visual inspection method of tablets ends with three high-speed cameras and comparison of the received images with images stored in the Atlas tolerance tablets VVER (Annex A TU 95 1823-2001) in the automatic mode.
   The system is integrated into the structure of the complex tablets grinding at JSC NCCP.
   The system is controlled by a specially designed program that is installed in a personal computer, mounted in an electronic equipment rack.
