ABSTRACT:
Method and apparatus for minimizing diversion of radioactive samples from a nuclear fuel sampling system. The apparatus includes a sampler for drawing a radioactive sample from a remote vessel containing nuclear fuel. The sampler is located within a shielding enclosure that has solid walls for preventing direct physical access to the sampler. A tray is located in the wall of the enclosure and is used for translating a sample vessel in and out of the enclosure. The apparatus further includes a time lock escapement that periodically immobilizes the tray for a period of time sufficient to minimize diversion of the radioactive samples.
