From Abstract: "The heat treatment and mechanical properties of four zirconium alloys...were investigated. Tensile, hardness, Jominy end-quench, and metallographic data constitute the basis for much of the report. Other data reported include the results of high-temperature creep, tensile, hardness, cold rolling, thermal-cycling, and dynamic-modulus tests." A connection is made between the behavior of these four alloys and more alloys in the zirconium-uranium system.

A report regarding a survey of the condition of wells and springs in the Rio Blanco County, in N.W. Colorado.

Report discussing progress made by the National Research Corporation in developing preparation of ductile zirconium for the month of December, 1949.

The following report provides tables that measure the pressure of hydrogen fluoride at given temperatures and the hydrolysis of uranium tetrafluoride.

Quarterly progress report discussing research and development of the Hanford Radiological Sciences Department, including personnel, facilities, and project updates.

Technical report. From Abstract : "The stoichiometric formula of the lower chloride in the BiCl3-Bi system has been established as Bi12Cl14 (BiCl1.167) through a dingle crystal, X-ray determination of its structure. ... Previous studies of the Bi-Cl3-Bi system are re-examined in the light of the structural results."

Our knowledge of the properties of mesons and their interactions with nuclei has come from two sources. Studies of cosmic ray phenomena provided the earliest information. The discovery that mesons may be produced artificially by bombardment of nuclei with radiations from high energy accelerators has, on the other hand, made it feasible to undertake a wide variety of investigations under more controlled conditions than is possible in cosmic ray experiments. In such experiments mesons have been produced by high-energy protons, alpha-particles and neutrons.

This program was established to develop new information concerning the mechanism of diffusion of fission gases (krypton and xenon) through UO2 and UC. The work was to concentrated on measurements of diffusion rates in unirradiated materials in the temperature range of 1000°C to above 2000°C, these determinations being important to the projected use of refractory fuel materials in high-temperature, high-burnup reactors.

Feasibility of conversion of uranyl nitrate to uranium trioxide by the continuous addition of concentrated uranyl nitrate solution to hot, agitated UO3 powder.
