Iodine Monitoring at the National Reactor Testing Station

Description: Operations at the National Reactor Testing Station generally involve new types of fuel elements or reactors or the chemical processing of spent fuel elements. Because the isotopes of iodine are produced in high yield during fission and their short half lives permit equilibrium concentrations to be built up rapidly considerable inventories of these isotopes will be present after a reactor has operated for a relatively short length of time. The gaseous nature of the element allows its escape afte… more

The Formation of Detonation in Saturated Mixtures of Knallgas-Steam and in Stoichiometric Mixtures of Deuterium-Oxides (Heavy Knallgas) when Saturated with Deuterium Oxide (Heavy Water). Final Report

Description: The purpose of this investigation was to determine the reaction characteristics of saturated mixtures of knall gas (stoichiometric mixture of hydrogen and oxygen) --steam and mixtures of heavy knall gas (stoichiometric mixture of deuteron and oxygen) saturated with heavy water. These mixtures were studied experimentally over composition ranges from no reaction limit to enriched compositions which supported detonations. (auth)

The Dielectric Tube Resonator : a Slow-Wave, Open Boundary, Dielectric Resonator for the Generation and Measurement of Millimeter and Sub-Millimeter Wavelength Electromagnetic Radiation. Technical Report No. 2

Description: The yet unsolved submillimeter wavelength problem, namely, providing a source of high-power, coherent, monochromatic signal frequencies in the region 300 to 3000 kmc/s, together with suitable measuring techniques and devices, is considered. The dielectric tube resonator is proposed to deal with this problem. It consists of a hollow, circularly cylindrical tube of dielectric material suitably terminated at its ends by sufficiently large metal end walls and constitutes a slow-wave, open-boundary,… more

A Report on the Kinematics of High Energy Electron Scattering

Description: "A convenient summary is given of useful formulas on the kinematics of high energy electron scattering together with a derivation of the relevant formulas for transforming from the center of mass to the laboratory system such parameters as scattering cross sections. The formulas derived hold for any two- body collision: the approximation (m = 0) employed for the electron scattering calculations is rigorously true for the elastic scattering of photons."

Low Energy Nuclear Physics : Second Annual Report for the Period February 1, 1959 to January 31, 1960

Description: The general expression for the angular correlation between radiations produced in successive cascade transitions is derived by use of Racah algebra. The result is then specialized to the beta - gamma correlation and applied to two cases in which additional properties of the photon are specified, the circular polarization and the plane polarization. The prospect of testing time reversal and determining nuclear matrix element ratios by beta - gamma correlation measurements is explored using the n… more

Organic Coolant Reclamation Annual Report : December 15, 1958 through December 14, 1959

Description: Potential methods have been examined for the reclamation of high boiler arising from the degradation of polyphenol materials in use as reactor coolants and moderators. To define the chemistry of potential reclamation processes, model polyphenol compounds were used. These include biphenyl, o, m and p-terphenyl, and p-quaterphenyl. Emphasis has been on hydrocracking, redistribution (reaction with benzene), and partial reduction. Preliminary study has been made of the application these techniques … more

Studies of Reactor Containment : Monthly Technical Progress Report No. 29

Description: The report covers work performed during the period September 1, 1959 through September 30, 1959. The general objectives of the program of "Studies of Reactor Containment" are to accomplish theoretical and experimental investigations of the loads to which external containment structures for nuclear reactors are subjected in the vent of a violent incident at the reactor core, the evaluation of methods of reducing that loading, and the study of the response of and design criteria for external con… more

Present Status of Semiconductor Particle Counters

Description: This review lists some of the salient features of semiconductor particle counters and cannot claim to contain an exhaustive listing of all the work in the field. Performance results on the surface-barrier counters as developed at California Institute of Technology are included as typical for this type of counter, though comparable results have been obtained elsewhere.

Determination of Possible Failed Blanket Elements Using the FEDAL System. Section I. First Performance. Core I, Seed 1. Test Results DL-S-2810S, RNI-24

Description: The purpose of the test was to determine if failed blanket elements exist in other regions of the core beside F-2. FEDAL sampling ports that have indicted the greatest deviation as determined in a statistical analysis performed on a number of traverses in the FEDAL system will be tested. Data obtained from the start up runs of the FEDAL sample port Nos. 11, 31, 36 and 37 of Monitor 2 and port Nos. 14, 46, 11, 49 and 7 of Monitor 1 gave no indications of a blanket element failure. At each power … more

Reactivity Lifetime. Section I. Third Performance. 2797-3797 EFPH. Core I Seed I.

Description: The PWR Plant was operated at approximately 60 MW net electrical output for a total of 1000 EFPH from February 3, 1959 to March 28, 1959. During this period, while performing DL-S-225, there were two planned shutdowns, no safety shutdowns or safety insertions and one flux title. The performance of the plant was satisfactory during the period of the test.

The Lindemann and Grüneisen Laws

Description: The Lindemann assumption of direct contact of neighboring atoms at fusion is replaced by the criterion that melting occurs when the root-mean-square amplitude of thermal vibration reaches a critical fraction ρ, presumed the same for all isotropic monatomic solids, of the distance of separation of nearest-neighbor atoms. The Debye-Waller theory of the temperature dependence of the intensity of Bragg reflection of x-rays is used, without further assumptions, to derive a generalized Lindemann law… more

An Empirical Distribution Function for Sampling with Incomplete Information

Description: In ordinary sampling one observes directly values of a random variable. There are, however, certain investigations in which the result of each observation is not a sample value of the random variable being tested, but only a number together with the information that the sample value is less than, or greater than, that number.

The Determination of Thorium in Uranium-Thorium Alloys, Using Cupferron

Description: Technical report describing that the use of controlled amounts of carbonate, acting both as complexing agent buffer led to a fairly satisfactory procedure for the determination of Th in Th-U alloys, using cupferron. The alloy, dissolved in NHO2, in the presence of HF, is treated with H2SO4 and the mixture is evaporated in SO2 fumes. The solution is diluted and (NH4)2CO2 is added. Th is precipitated from this solution with cupferron. The precipitate is weighed as ThO2 after ignition. An accura… more
