Stock Poisoning Due to Scarcity of Food

Description: "It is generally recognized that the heaviest losses of livestock from poisonous plants occur in seasons when feed is short, but the intimate relation between such losses and the food supply does not seem to be appreciated at its full value. If it were understood and acted upon intelligently there would be much less complaint of harm done by poisonous plants." -- p. 2

Sulfur Poisoning of Fixed Beds of Iron Catalysts in the Fischer-Tropsch Synthesis

Description: From Introduction: "This bulletin describes the results of poisoning of fixed beds of reduced, carbided, and nitrided fused iron oxide catalysts and reduced steel turnings by H2S in 1H2 + 1CO synthesis gas in tests in which the temperature (1) was held constant and (2) was increased as required to maintain constant productivity."

Lead-Based Paint Poisoning Prevention: Summary of Federal Mandates and Financial Assistance for Reducing Hazards in Housing

Description: This report discusses the federal strategy to reduce childhood exposure to lead-based paint (LBP). The federal Lead-Based Paint Poisoning Prevention Act (LBPPPA), as amended, establishes requirements and authorizes funding for the detection and control of LBP hazards in federally assisted housing.

HIGHLY SELF-SHIELDED BURNABLE POISONS

Description: A new and different type of burnable poison element which can be used essentially to match any decreasing reactivity curve in a reactor and still have a tolerable residue was studied. Specific application is made to Gd as the poison elements; however, the results would be similar for any other suitable high cross-section element such as Cd. (J.R.D.)

Localized Pd Overgrowth on Cubic Pt Nanocrystals for Enhanced Electrocatalytic Oxidation of Formic Acid

Description: Single crystalline surface such as (100), (111), (110) has been studied as an idealized platform for electrocatalytic reactions since the atomic arrangement affects a catalytic property. The secondary metal deposition on these surfaces also alters the catalytic property often showing improvement such as poisoning decrease. On the other hand, electrocatalysts used for practical purpose usually have a size on the order of nanometers. Therefore, linking the knowledge from single crystalline studies to nanoparticle catalysts is of enormous importance. Recently, the Pt nanoparticles which surface structure was preferentially oriented was synthesized and used as electrocatalysts. Here, we demonstrate a rational design of a binary metallic nanocatalyst based on the single crystalline study.

Microflora in Prepared Foods Dispensed from Eating Establishments in Dallas, Texas

Description: A bacteriological study was made of a number of prepared foods that were bought ready-to-eat, for home consumption, from several food establishments in Dallas, Texas. The purpose of this study was to show whether these foods could be a potential source of food poisoning; whether there are any particular foods that should have greater care than others in order to protect their quality; and whether the bacteriological contamination could have been prevented by strict observance of the city regulations for handling foods.

Hydrogen Permeation Measurements of Partially Internally Oxidized Pd-Al Alloys in the Presence and Absence of CO

Description: Specific permeabilities and diffusion constants for H have been measured in a series of Pd-Al alloy membranes using a new method for activation of the membranes. The membranes have been partially internally oxidized at an elevated temperature before inserting into the apparatus for measuring H2 permeabilities. It has been observed that the kinetics of H2 absorption are faster for internally oxidized Pd-Al alloys than for pure Pd foil [1] and, in addition, the partially internally oxidized alloys offer a greater resistance to poisoning by CO(g) [2].

Cathode/Interconnect Interactions

Description: The objectives of this project were to examine chromium poisoning in full cell tests, evaluate chromium release rates for oxides, and examine the effects of chromium in the cathode.

CROSS SECTIONS FOR REACTOR ANALYSIS

Description: A listing of the data on the revised tape is presented. The nuclear data are a reproduction of the computer printout. Other nuclear data (spectra, energy, absorption cross section of some poisons and absorption and fission cross sections of selected fuel materials) were transcribed from the tape listing to provide a more compact format or to allow easier comparison of absorbers and fuels.

The Genetically Remote Pathogenic Strain NVH391-98 of the Bacillus cereus Group Represents the Cluster of Thermophilic Strains

Description: Bacteria of the Bacillus cereus group are known to cause food poisoning. A rare phylogenetically remote strain, NVH391-98, was recently characterized to encode a particularly efficient cytotoxin K presumably responsible for food poisoning. This pathogenic strain and its close relatives can be phenotypically distinguished from other strains of the B. cereus group by the inability to grow at temperatures below 17 degrees C and by the ability to grow at temperatures from 48 to 53 degrees C. A temperate phage, phBC391A2, residing in the genome of NVH391-98 allows us to distinguish the three known members of this thermophilic strain cluster.

XENON TRANSIENT, 761.3 EFPH. CORE I, SEED 2. Section 1. Test Results T- 612081

Description: >Tests were conducted to determine if there is sufficient excess reactivity in the Shippingpont PWR to override a peak xenon transient and to obtain data for rod worth calculations. Upon completion of 761.3 EFPH of operation on core I, Seed 2, there was sufficient excess reactivity in the core to override the peak xenon transient which occurred 9 hr after station shutdown. At that time the controlling rod group (group II) was at a height of 38.43 in., while groupI rods were fully withdrawn and group-III ard -IV rods were fully inserted. The rod worth values for the groupII rods decreased with increasing EFPH for Core I, Seed 2, for the first 20 in. of rod withdrawal. (J.R.D.)

XENON TRANSIENT TESTS. CORE I, SEED 2, 149.8 EFPH. Section 1. Test Results T-612081

Description: A test was made to determine if there is sufficient excess reactivity in the core to override a peak xenon transient and to obtain dath for rod-worth calculations. After 149.8 EFPH's of plant operation on seed 2, there was sufficient excess reactivity to override peak xenon. Criticality during peak xenon was maintained with group III and group IV rods inserted, group I rods withdrawn to approximately -69 in., and group II rods withdrawn to approximately - 29 in. The override of peak xenon occurred 8 hr and 45 min after shutdown. (W.L.H.)

TWO-REGION REACTIVITY WORTH METHOD FOR ANALYSIS OF FUEL-POISON SUBASSEMBLIES

Description: In the early production of reactor cores, a final nondestructive method to insure proper loading of fuel-poison subassemblies was desired. Subsequent analytical studies are presented which indicate that two-region reactivity measurements, as obtained from a suitable critical facility, should determine subassembly loading to within 2g U and 0.03g B. Increased confidence in fuel component assembly methods resulted in a decision to abandon use of this method and, as a result, it has never been put into practice at the Bettis Laboratory. (auth)

LECTURE NOTES ON REACTOR CONTROLS

Description: This material is the outgrowth of the notes prepared for lectures on reactor controls given in 1953-55 at the Oak Ridge School of Reactor Technology. The course on reactor controls was for the purpose of acquainting the student with some of the elementary considerations involved in setting up a control and safety system for a nuclear reactor. Topics are discussed on kinetics, neutron energies, poisoning, analog computing, instrumentation, start-up, neutron sources, etc. (W.D.M.)

THE DEPLETION OF BURNABLE POISON IN ENDURANCE CALCULATIONS

Description: Methods of relating the bunnable poison concentration in a reactor to the fuel concentration during the life of the core are presented. These methcds correspond to the following ways of using bunnable poison: (1) in discrete lumps, (2) in a homogeneous rnixture with the fuel, and (3) a combination of these. Nuclear data relevant to the U/sup 235/-B/sup 10/ system are presented. (auth)
