METHOD OF CHECKING OF FUEL ELEMENTS Russian patent published in 2006 - IPC G21C17/00 

FIELD: atomic power engineering.

SUBSTANCE: according to proposed method of checking of fuel elements, in process of manufacture of jacket of fuel element, plug is preliminarily marked, number is read off, jacket is weighed and data are entered into computer and after charging of jacket with nuclear, number is read off, filled jacket is weighed, net weight of nuclear fuel is determined and data are entered into computer. After sealing and checking, number is read off and entered into computer and before assembling of fuel element, number is read off and data are entered into computer.

EFFECT: possibility of tracing fuel elements along technological flow from moment of manufacture to assembling into fuel element cluster, revealing and isolating fuel elements which do not comply with requirements at exclusion of distortion of temperature and neutron fields in nuclear reactor.
