Report issued by the Bureau of Mines over investigations of coking coal reserves of Anderson County, Tennessee. Testing to determine suitability for producing metallurgical coke is also presented. This report includes tables, maps, photographs, and illustrations.

From introduction: This report concerns work done by the Geological Survey on behalf of the U.S. Atomic Energy Commission concerning sandstone-type uranium deposits.

The following report discusses the development of methods for sealing the ends of metallic-cored fuel rods.

From abstract: "This report consists of papers presented of papers presented at a meeting held in late 1954 to review all the work related to coil design and fabrication."

Abstract: The reactor kinetics equations are combined into a single integral equation whose kernel describes the time-dependent characteristics of the reactor including six delayed groups of neutrons. Numerical solutions of the integral equation are given for constant, linear, and ∫sin²kx dx reactivities. An approximate solution of the integral equation is obtained which provides a basis for the formulation and solution of the reactor system control problem using the methods of servomechanisms theory. The reactor frequency response function, a product of the approximate solution, is calculated and plot given.

Report describing data resulting from dynamic tests to determine applied potential corrosion of aluminum.

From general background: "In the experiment to be described, various targets were bombarded with protons in the 40-140 Mev region, and the R-ray spectra were detected and analyzed."

Report discussing a possible solution for providing a remotely operated way of handling samples at an irradiation facility. Explanation of operating requirements, equipment, and a possible layout is included.

Report discussing a test aimed at determining if high velocity water could cause severe pitting in 72-S aluminum. This test was designed after an increase in the amount of pitting-caused water leaks in reactors.

This document provides tables which give the computed acid, silicate, and silica requirements which will be necessary after completion of the water treatment plant expansion programs.

In the reference letter and later letters the author made recommendations pertaining to the programs of AEC National Laboratories and other AEC contractors in direct support of the Savannah River project during FY-1956. He believes that these recommendations should now be revised in view of schedule changes ad in the light of accumulated experience. The estimated cost of the programs recommended earlier totaled $2,083,000 for FY-1956. The estimated cost of programs currently recommended total $2,048,000 for FY-1956. The programs mentioned in succeeding paragraphs are concerned mainly with the development of processes for producing extended surface fuel elements and, to a lesser extent, with the development of separations processes. The author considers these particular supporting programs important to the rapid and successful achievement of development objectives at the Savannah River Plant and accordingly recommend that the Commission sustain them. Two of the programs, specifically the work by Sylvania and by Horizons to develop processes for reducing thorium oxide to metal, are not now associated with meeting future production objectives at the Savannah River Plant. The author believes that these programs should be brought to an orderly conclusion, as previously planned, to avoid any loss of the art developed to date.

This report provides justification for a metal loader for ``C`` elevator for the 100-B,D,DR,F, and H Areas. This proposed work is justified on the basis of increased irradiation capacity for plutonium production and miscellaneous improvements in efficiency of reactor front face work.

This document presents a summary of work and progress at the Hanford Engineer Works for November 1955. The report is divided into sections by department. A plant wide general summary is included at the beginning of the report, after which the departmental summaries begin. The Manufacturing Department reports plant statistics, and summaries for the Metal Preparation, Reactor and Separation sections. The Engineering Department`s section summarizes work for the Technical, Design, and Project Sections. Costs for the various departments are presented in the Financial Department`s summary. The Medical, Radiological Sciences, Utilities and General Services, Employee and Public Relations, and Community Real Estate and Services departments have sections presenting their monthly statistics, work, progress, and summaries.

From abstract: The test program gave information about compatibility of materials and demonstrated the particular requirements of bearing surface preparation.

In connection with the antiproton investigation at the Bevatron we planned and carried out a photographic-emulsion exposure in a magnetically selected beam of negative particles. The magnetic system was identical to the first half (one deflecting magnet and one magnetic lens) of the system used in the antiproton experiment of Chamberlain, Segre, Wiegand, and Ypsilantis. The selected particles left the copper target in the forward direction with momentum 1.09 Bev/c.
