Selection and testing of on-line samplers for head-end reprocessing

The General Atomic cold reprocessing head-end pilot plant contains a number of processing steps. Samplers are required to obtain on-line information on the performance of each step. A number of samplers have been selected and tested. The different types of samplers are described and potential sites in the pilot plant are discussed. Initial tests results with simulated process materials are presented. Ideas for other samplers are discussed.
