Census 2000: A National Process Requires Local Focus: Report to Congress, 1 February 1999

Description: Report by the Congressional Members of the U.S. Census Monitoring Board criticizing the plans of the Census Bureau and the Department of Commerce to use statistical adjustment to correct any potential undercounts in the upcoming 2000 census.

Fission Fragment Ionization and Electrical Power Production

Description: "A reactor concept is discussed consisting of parallel plates, spaced with a gap equal to plate thickness with a 2.0 v potential available across the gap. Fissions are assumed to take place in a mixture of U and Ar gas between the plates. The operating scheme is as follows: U fissions in the gas; the fission fragment energy is almost all absorbed by ionization of the gas, leading to a high ion pair density in the gas; positive and negative particles are swept out of the gas by the 2.0 v field, … more

Hydrostatic Journal Bearing Water Tests Conducted in Modified PK-A Pump

Description: A hydrostatic journal bearing mounted near the impeller of an overhung vertical shaft centrifugal pump was subjected to water testing as a part of the molten salt lubrication investigation at ORNL. Three tests were performed with bearings having radial clearances of 0.003 in., 0.0075 in., and 0.005 in. The first journal and bearing (0.003 in. radial clearance) were found to be heavily scored after testing. Only faint localized scratches were found on the second journal (0.0075 in. radial cleara… more

Preliminary Estimate of the Cost of Production of 10% Isotopic Purity Oxygen-17 by Chemical Exchange

Description: An order of magnitude estimate was made to determine a minimum cost for 10% pure oxygen-17 when produced by a chemical exchange process. the calculations were based on separations factors of 1.03, 1.01, and 1.003. the cost of product was found to vary from $23 per gram for the large factor to $165 per gram for the smaller.

A Comparison of Some Piezoelectric Ceramics

Description: This memorandum summarizes some of the basic physical properties of barium titanate, lead-zirconate titanate, and lead metaniobate which are of importance to the use of these materials as piezoelectric transducers. Emphasis is placed on the advantages of lead metaniobate due to its extended temperature range of operation and on the importance of further work to improve the quality of this material.

Enthalpies and Heat Capacities of Solid and Molten Fluoride Mixtures

Description: The enthalpies and heat capacities of seventeen fluoride mixtures in the liquid state have been determined using Bunsen Ice Calorimeters and copper block calorimeters. The fluoride mixtures were composed of the fluorides of two or more of the following metals: lithium, sodium, potassium, beryllium, zirconium, and uranium. The enthalpies and heat capacities of most of these mixtures were studied in the solid state also. Estimates of the heat of fusion have been made. General empirical equations … more

Interim Report -- The Retention of Particles in Ducts Transporting Aerosol Streams

Description: Accurate sampling of particulate in gaseous effluents is required for auditing and control of radioactive wastes released to the environment at installations generating or processing radioactive materials. Over the years a variety of sampling probe configurations, sampling velocities, lengths and sizes of sample delivery lines have been used locally to obtain these samples. Efforts to properly evaluate the validity of samples in most sampling installations have been hampered by a lack of basic … more

The Use of Tetravalent Uranium and Hydrazine as Partitioning Agents in Solvent Extraction Process for Plutonium and Uranium

Description: In solvent extraction purification processes such as are used at Hanford, the fuel elements or "slugs" from the reactor containing uranium, plutonium, and fission products are dissolved in nitric acid, adjusted to the required feed composition, and pumped to the solvent extraction columns. Figure 1 in a schematic diagram of such a solvent extraction process. In the A column, the uranium and the plutonium are extracted into an organic phase while the bulk of the fission products remain in the aq… more

Heat Transfer in Radiant- Heat Spray Calcination

Description: The fixation of aqueous radioactive wastes in a stable solid media by means of calcination has been the subject of considerable research and development effort. Several methods of doing this on a continuous basis have been devised and a few have been demonstrated to be feasible for the handling of non-radioactive or low activity simulated wastes. Currently an investigation of calcination by means of radiant-heat spray drying is being carried on by the Chemical Research Operation of the Hanford … more

The Microbeam as a Tool in Radiobiology

Description: In the analysis of the effect of ionizing radiation on living systems, the problem is complicated by the interaction of one part of the system with other parts. If an entire mouse is subjected to radiation, only a few of the most radiosensitive organs, the "weak links," react to the insult and essentially limit the size of the dose delivered since there is little to be learned from irradiating a dead mouse. Thus an insensitive organ like muscle will not respond at all to a total body dose. Like… more

Mitotic Indices of Human Bone Marrow Cells. Duration of Some Phases of Erythrocytic and Granulocytic Proliferation Computed From Mitotic Indices

Description: Data on the mitotic indices of human bone marrow cells were reported in the first paper of this series, and theoretical considerations on the applicability and limitations of the index in determining kinetic parameters were discussed. In the present paper an attempt is made to compute time parameters of normal bone marrow cell proliferation from the data presented in the first paper.

The Effects of 250-kv X-Ray on the Dog's Pancreas: Morphological and Functional Changes

Description: Previous investigations that the pancreas is a radioresistant organ. Ivy in 1924 noted the presence of a fibrotic atrophic pancreas in a dog which had received one erythema dose to the epigastrium. Fisher in 1923 reported that four to five erythema doses delivered in a single application caused complete disappearance of the irradiated pancreatic remnant in about two months. These dogs died because of uncontrolled diabetes. One dog that received four erythema doses (possibly 200 r) was sacrifice… more

Elimination of Phases the Life Cycle of Leukemic Cells From in Vivo Labeling in Human Beings With Tritiated Thymidine

Description: Our earlier in vitro studies have suggested that malignant tumors may not produce new cells more rapidly than normal cells are produced in the "steady state" equilibrium. Obviously tumors of all typed represent a diversion from "steady state" production with a net gain in mass of tissue. However, the increase in mass is not necessarily constant and may fluctuate in the natural history of the disorder. DNA labeling with tritiated thymidine had made it possible to characterize normal "steady stat… more
