Abstract
Systems for, within a sealed environment, determining the bulk density of radioactive nuclear fuel particles flowing in a process stream. A carrier having a known weight and a channel of known volume is selectively shuttled between the flowing particles and a weigh cell. Thus, from the weight of a known volumetric sample, the bulk density is determined. The carrier and selected portions of the cell and carrier transporter are enclosed within a sealed structure to contain the radioactive material within a controlled environment. Subsequent to density determination, the particle sample is dumped, preferably back into the flowing stream, by structure which rotates the carrier or opens a door at the bottom of the channel. The systems also provide for sealing of the housing at various positions of the carrier.
