Analytical requirements of the 234-5 Project

At this time it is desirable that preliminary estimates be made of the manpower, equipment, space, layout and facility requirements of the analytical section for the 234-5 Project. To arrive at these requirements a rough estimate of the required analyses, their scope and their frequency has been compiled. This is expected to serve as a basis for the Laboratories Division to outline their space and equipment requirements as soon as possible and to assemble the required personnel for operation later. Crucial elements encountered in the process are classed as light impurities or as metallurgical impurities. The light elements are undesirable due to the {alpha}, n reaction with plutonium. The metallurgical impurities are undesirable since they change the physical properties of plutonium. The light elements undesirable in the finished product and the approximate tolerances (in ppM of plutonium) acceptable for each are listed assuming all other elements listed are absent. A list of the undesirable metallurgical impurities with the tolerances (again expressed in ppM of plutonium) for each element, assuming the other elements are absent are given
