From abstract: "A scintillation detector has a pulse height output which is a linear function of the energy of impinging gamma radiation. A pulse height analyzer system determines the amplitude distribution of this train of pulses. The system also displays this information graphically in a form which is convenient for further analysis."

From introduction: This report describes the program of research on mineralogy and petrography of certain uraniferous vein deposits in the Boulder batholith of western Montana.

Technical report outlining cavity-type ionization chambers with graphite walls that are used to measure heat dissipation in the graphite reflector of the MTR mock-up. Studies the relationship between the ionization occurring in the chamber and the heat generated in the surrounding graphite medium. [From Abstract]

Technical report covering work completed on the removal of radioisotopes from water using a calcium phosphate floc as a carrier. This research was performed as part of the Health Physics Waste Disposal Research Section work on the removal of small quantities of radioactivity from large volumes of water. [From Abstract]

Technical reports outlining the controls for the Homogeneous Reactor Experiment (HRE); controls are divided into three principal groups. 1. Reactor. 2. Process or auxiliary. 3. Power generation. These are the classifications designating the primary functions of the controls. [From Introduction]

From introduction: "In this report we consider a few non-adiabatic processes. The types to be discussed will be limited because of two reasons: first, complete descriptions are available for some processes; second, as time goes on alternative injection methods undoubtedly will be discovered, so this list must necessarily be incomplete."

From introduction: A subsurface exploration program was undertaken to investigate the concentration of uranium and vanadium in or near the base of the Shinarump member of the Chinle formation in the Flatirons locality, and to develop criteria whereby adjacent unexplored areas could be evaluated as to potential production capacity from study of geological and mineralogical features at the host rook outcrop. An earlier study of the area by C. G. Evensen of the U. S. Atomic Energy Commission had shown that geological conditions favorable to the accumulation of commercial uranium deposits were present in the Flatirons area.

Abstract: The Trans-Pecos region of southwest Texas is noted for the production of quicksilver, lead, silver, and copper from its several mining districts. Reconnaissance, which was concentrated in and around these districts, revealed many areas of slightly abnormal radioactivity. Only a few areas, however, showed uranium mineralization.

From abstract: This proposal for a 6"D column plant is based on laboratory and pilot plant work done at Oak Ridge and at Model City.

Cost estimates for two types of Th producing plants are offered. One utilizes Th(NO3)4 as raw material, the other uses monazite sand. Final processing schemes and plant designs are not fixed, so the estimates represent maximum costs. Recommendations for research and development of Th producing methods are given.

Report discussing the progress made on research concerning sluge-supernate acidification. This report focuses mainly on "'reverse strike' acidification and the observations of the physical characteristics of the test material," which was a synthetic incubated metal waste.

Discussing recommendations for wagon drilling in the Temple Mountain District, Utah

This report describes the Temple Mountain district in Utah, specifically four Shinarump-capped areas that are recommended for ore mining.

This report is part one of a series of two parts to a memorandum. The work discussed here presents the results of extensive calculations on the attention of gamma rays by shields of lead and iron.

Abstract: "The energy-dependence of the formation cross section of certain nuclides formed in fission of uranium and thorium has been studied. Excitation functions in the hundred-Mev region are given for Ni66, Zr97, Ag111, Ba131, and Ba139. Protons, deuterons, and alpha particles from the Berkeley 184-inch frequency modulated synchro-cyclotron were used to induce the activities."

From abstract: This investigation was conducted in order to develop a process whereby the most abundant zirconium ore, namely zircon, could economically be put into solution and purified adequately for use in hafnium separation processes employing liquid-liquid extraction. Secondary aims concerned the preparation of pure zirconyl chloride, zirconyl nitrate, zirconyl sulfate, and zirconium oxide from the zircon ore.

Report presenting data on the thermal conductivity of fuel element materials with short summaries.

From introduction: "A study of the fission product activity-fixing properties of the Savannah River Project soils was undertaken by this site to provide data for the planning of the waste disposal program for the Savannah River Project."

The following report studies a method of freezing ice plugs in pipe lines before flanges are disconnected, the intention is to prevent light water from entering the system when equipment is removed for repairs.

The following report uses empirical relations and the elementary diffusion theory transformation, the EDIT, to predict some of the minimum critical values of the various parameters of interest with reasonable accuracy. This document reports the minimal critical mass, volume, and cylinder diameter for uranium of 4.9% assay.

Abstract: "The effect of variation in fuel element density upon f, p in a D2O cooled and moderated lattice of cylindrical fuel elements is investigated. The CP-3 lattice is chosen as a reference. The effect of a source term in the fuel element is considered. f, p are calculated as functions of "a", the ratio of the modified fuel element density to the original (fuel only) density. Curves showing f(a), p(a) are included. It is concluded that a 1 per cent decrease in the product, f(d), p(a) is not suffered until a=0.3. A 5 per cent decrease in k is estimated at a-0.4. The necessity of introducing the fuel element source term into the calculation after a has been decreased to about 0.6 is brought out."

The following report describes results from a study of three types of cement (Barytes, Brookhaven, and Portland) exposed in the ORNL Reactor for periods of seven and twenty-eight days.

Abstract: "A description of the demand computer and its functions is given. Methods of testing and adjusting, and gain and response curves for the system and its parts are included."

This report describes how to achieve the variation in maximum power density and maximum heat flux of the core and blanket thorium plates in the converter reactor with irradiation time.
