METHOD OF REMOTE MEASUREMENT OF FUEL ELEMENT PARAMETERS Russian patent published in 2008 - IPC G21C17/06 G01F17/00 

FIELD: physics.

SUBSTANCE: said utility invention relates to the instrumentation and may be used for determining parameters of bodies, mainly for remote determination of parameters of radiated fuel elements. According to the invention, for remote measurement of fuel element parameters, an empty grip is weighed and the sample held by the grip is weighed, in the air. After that, the sample and the grip are immersed in the working fluid and weighed after their immersion in the working fluid. The results are used for calculating the initial density of the working fluid. The fuel element held with the grip in the air is weighed. The fuel element with the grip are immersed in the liquid, to various depths, and weighed after each immersion. After that, the partial volume of the fuel element is calculated; the partial volume being the volume contained between the two successive cross sections of the fuel element coinciding with the surface of the working fluid in the vessel at two successive immersion stages; after that, this volume is used for calculating the average area of the fuel element cross section and the full volume of the fuel element.

EFFECT: increased accuracy of fuel element parameter determination.
