This volume which deals with the radiochemistry of uranium is one of a series of monographs on radiochemistry of the elements. There is included a review of the nuclear and chemical features of particular interest to the radiochemist, a discussion of problems of dissolution of a sample and counting technique, and finally, a collection of radiochemical procedures for the element as found in the literature.

The elements Sn, Mg, Ti, Zr, Hf, Si, Cd, and U were alloyed with plutonium to determine their effect on stabilization of the beta phase. Zirconium was found to be the ' most effective. Kinetic studies were conducted on Pu-Zr alloys having 0.24, 0.65, and 1.7 at.% Zr contents. The beta to alpha transformation in the Pu-Zr alloys was somewhat similar to that in unalloyed plutonium. The main difference being that time, temperature, transformation curves of the alloys were shifted to the right as the zirconium concentration increased. It was determined that the amount of beta phase retained at room temperature increased as the zirconium concentration increased. The minimum amount of Zr needed to stabilize the beta phase of plutonium at room temperature was determined to be 2.0 at.%. A 2.4 at.% Zr addition stabilized the beta phase of plutonium at atmospheric pressure from room temperature to 265 deg C. During mechanical property testing it was determined that the stabilized beta Pu-2.4 at.% Zr alloy was brittle from room temperature to 230 deg C. Both tensile and compression strengths of the beta stabilized alloy were greater than the unalloyed beta phase of plutonium. A brittle-ductile transition was noted between 130 …

A list is presented of subject headings used by the U.S.A.E.C. Division of Technical Information for indexing literature in the field of nuclear science and technology. (C.H.)

Unclassified references (344) to information on nuclear batteries, thermoelectric cells, thermionic cells, and the SNAP program are given. (N.W.R.)

References applicable to the problems of transponting charged particles in the areas external to accelerators are presented. The 891 references cover the period 1949 to 1981, with a few references both prior and subsequent to this period included. Part I is concerned with the more general aspects of electron optics. Part II contains the references that deal more directly with applications to particle accelerators. Arrangement within each pant is by broad subject with cross references listed at the end of each section. An author index is included. (M.C.G.)

This report provides a summary of the Nuclear Effects Group Program for fiscal year 1963. Efforts in space physics and instrumentation are detailed for the space exploration effort. Pinex type experiments are proposed, as are Phonex, Nuclear Emulsion Research and Low Energy X-Rays Measurements projects.

A summary is given of studies carried out with the UO/sub 2/-- NaK slurry system to ascertain its potential properties as a fuel for advanced reactor system. Included are the studies of the physical-chemical properties of the slurry, the early loop investigations, in-pile studies, and the exploration of the engineering system behavior of the material. The work was carried out in three different institutions. The Argonne Nattonal Laboratory was responsible for the early loop studies and the in-pile work, as well as some phases of the physicochemical behavior. The engineering studies were carnied out for ANL by the Mine Safety Appliances Corporation, Callery, Pennsylvania, The physicochemical studies were performed by the Armour Research Foundation, Chicago, Illinois. The studies under the program were relatively modest, but they did serve to demonstrate some of the attractive properties of the material as well as its limitations. Specifically, the dropout behavior was demonstrated in piping a tank systems in both conventional and specially designed systems, Hydraulic characteristics were demonstrated, and it was observed that a 10 vol% slurry was the maximum concentration that could convenientiy be handle in conventional engineering systems. In-pile performanc of the slurry was demonstrated and it was concluded that slurries …
