| 摘要 |
Equipment for inspecting the filling of nuclear fuel rods, partic. plutonium filled rods, has a mechanism (2) for moving the rod (3) axially and/or rotating it and a gamma source (8) directed at the measuring point of a gamma detector (5). Pref. the gamma source is: iridium 192, caesium 137, mercury 203, or protactinium 231. The angle (14) between the gamma source and the detector is pref. 50-70 deg., esp. 60 deg. The gamma source may be an X-ray tube. USE/ADVANTAGE - For measurement of the total quantity of fuel mixture components in a nuclear fuel rod. Makes possible the measurement of fuel isotope components which do not, spontaneously, emit gamma rays.
