The Preliminary Study of High-level Radioactivity Sludge Ⅲ.Study on Sampling System and the Sampling Action of the HLRS

An integrated sampling facility is designed for sampling high-level radioactive sludge(HLRS). The designing guideline, structure of components, assembling and operation are described in detail. The sampler has been successfully used to sample HLRS from HLLW storage tanks for many years. The operation experience indicates that the sampler works safely and reliably. By using this sampler a requested volume of HLRS can be quickly sampled from any selected position in storage tank.
