The RaLa process is operated in Building 706-D for approximately one week in five weeks. The process consumes about seventy-six, four-inch Hanford slugs per run. Approximately thirty grams of Plutonium are handled during each run. Plutonium and Uranium are waste products of the RaLa Process. Description of the process includes steps beginning with the dissolving of aluminum coating and removal of discharged radiochemical waste. Sampling of product takes place throughout the process. The blister sampler consists of an air jet designed to circulate solution from the tank to be sampled through a glass sample cone and bank to the tank. Samples are removed from the blisters and transportated to the laboratory in a lead carrier for analysis. A Uranium analysis is regularly run on the slug dissolvings n order to determine the completeness of the dissolutin by balance against the slug count. No analysis for Uranium is run on the waste samples, and no analysis for Plutonium is run on any of the samples.
