FIELD: energy.SUBSTANCE: invention relates to nuclear power engineering and can be used in making annular fuel elements of nuclear reactors. Apparatus for controlling characteristics of fuel column of annular fuel elements comprises a row of blocks 1-4 for detection of gamma-radiation of fuel column and blocks 5, 6 for detection of gamma-radiation passing through fuel column. Source 13 of gamma-radiation is fixed on end of bar 12, intended for introduction into cavity of fuel element 9. Mechanism for moving fuel element is configured for translational movement of fuel element 9 along its axis and includes mechanism 8 for gripping and turning fuel element 9 about its axis by 90 degrees. Two blocks 5, 6 for detection of gamma-radiation are located on opposite sides of fuel element displacement axis 9. Control unit is connected to detection blocks and to displacement mechanism of fuel element 9.EFFECT: technical result is possibility, in one pass of annular fuel element, of obtaining all necessary quality characteristics of its production.1 cl, 3 dwg |
