Heat Transfer from Spent Fuel and Blanket Subassemblies During Transfer from Reactor to Decay Storage Facility. Technical Memorandum No. 2

Description: During the transfer of spent fuel and blanket subassemblies from the reactor to the decay storage the subassemblies must be moved through an inert gas The heat generation due to the decay of fission is sufficiently large that provisions must be made for cooling the subassembly when in the gas The transfer equipment was designed for conduction radiation and natural convection cooling only. Various steps in the transfer process are explained and computations on heat generation and transfer are gi… more

Relations Governing Low Cycle Fatigue : a Summary of the Pertinent Literature

Description: The information available to date on low-cycle fatigue, resulting from either repeated mechanical straining (strain cycling) or from repeated temperature changes under restraint (thermal cycling and thermal shock), their relation to static and conventional fatigue properties, and their fundamental significance is assembled. In spite of the small amount of data accumulated on the effects of the numerous variables involved in low-cycle fatigue these data appear to conform to certain significant r… more

Control of Oscillation Amplitudes

Description: This report analyzes methods of correcting for the anti-damping of the radial betatron oscillations. Practical methods of reducing the anti-damping are to couple the radial and vertical betatron oscillations by means of a rotated magnetic quadrupole lens, or to add a magnetic structure which has a decrease in radiation loss for increasing radius of particles. It is shown that the damping ration cannot be changed by shaping the R.F. cavities.

Theory of the Thermal Breakaway of a Pinned Dislocation Line with Application to Damping Phenomena

Description: An investigation is made of the model of a pinned dislocation line under stress. The model used is that originally given by Koehler and later employed by Granato and Lücke in their theory of mechanical damping due to dislocations. By taking into account thermal fluctuations the probability of the thermal unpinning (breakaway) of such a dislocation line is calculated. The effect of the breakaway on the decrement and apparent modulus change felt by a stress wave traveling though a solid is also c… more

Irradiation Damage at Low Temperatures in the Noble Metals

Description: During the past year a great deal of new experimental information has become available concerning the nature of the damage produced in the noble metals by nuclear irradiation. In addition, several new theoretical calculations have appeared. The present survey attempts to asses our knowledge of the field. In particular, it attempts to five an atomic description of the natures of the damage introduced and of the changes which occur during thermal annealing in the novel metals below 60 K.

Transient Beam Loading In Linear Electron Accelerators

Description: "The subject of beam loading in linear electron accelerators has been discussed. With suitable design it is possible to place the equilibrium electron phase angle well ahead of the crest of the traveling wave in the accelerator. With beam loading the equilibrium position will move toward the crest, but the electron energy will remain constant or nearly so over a considerable range of loading. Some loss in energy will result from moving the equilibrium phase angle off the wave crest but the spre… more

Theory Of The Constant Gradient Linear Electron Accelerator

Description: "The effect of beam loading upon the design and performance of the accelerator is examined. Results are given in dimensionless form so that the various equations and grams can be used at any operating frequency. The constant gradient accelerator is somewhat less subject to beam loading than the uniform accelerator structure. For an accelerator of given filling time and 20% 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."

A Study of Location Times for Positions Arranged on a Panel in a Random and an Ordered Manner

Description: The results of an experimental pilot study on the location time, for a sequence of N specified positions on a panel, are given for 1 <_ N <_ 30. The positions to be located were randomly arranged on one set of panels and arranged according to an ordering scheme on a second set of panels. Th location time for N positions randomly arranged on a panel varies approximately as N(2). In the case of an order arrangement the location time is essentially proportional to N. Even for as few as 30 position… more

Frequency Components of a Step Function and a Sinusoid

Description: Fourier analyses are made on two functions. The first is a step function forward from periodic samples of a sinusoid. If the frequency of the sinusoid is less than one-half of the sampling frequency, it is shown that the step function has no frequency components less than one-half of the sampling frequency other than that of phase, and duration with respect to the interval of the analysis. It is shown that the insertion of a blank space in the period of analysis reduces greatly the uncertainty … more

Report of Fire in Laboratory Hood, Wing I, Building 4500

Description: The fire involved approximately 30 liters of isopropyl alcohol as a result of the ignition of about 16-18 liters of isopropyl alcohol and a slurry of thoria and ammonium nitrate in a 20-liter glass carboy. This material was undergoing a volume reduction by boiling in a floor-type metal hood with Plexiglas sides and 3 sliding door on the front of ordinary glass. The alcohol vapor was vents directly into the hood (Fig1.)
