Approximately 60 Cl slugs were dissolved and processed--the dissolving beginning April 1, 1951, and the product leaving the plant April 6, 1951. Some cold slugs were pushed from the pile by error; and the dissolver solution contained 248 Curies of Barium, considerably less than was expected. The crud filtration was slow, but the process filtration was fast. Hot solution backed up in the feed tank sparger line and in the blow tank to process filter line, as should have been anticipated. Operating changes will prevent future repetition. All instruments worked satisfactorily except the liquid level telemeter which behaved erratically throughout the run (a loose connection in the panel equipment). Data is given on product results. The product drying was slower than expected. Apparently the conduction of heat from the point of hot air entry at the top of the product cone, down the cone walls, and into the liquid at the bottom has a considerable influence upon the drying rate. The loading mechanism worked well, and the 164 Curies of product shipped on April 6 arrived at Los Alamos on April 8, 1951.
