Broad Range Spectrograph for Use With the Rochester 27" Cyclotron

Description: "A broad range nuclear spectrograph of the Buechner-Bainbridge type, which characteristic radius R-50 cm. has been constructed and installed for use in conjunction with the Rochester 27" variable energy cyclotron. For a given magnetic field, particles are focused over an energy range 0.63o‹E‹1.3Eo, where Eo is the energy of particles focused with orbit radius Q-R-50 cm. The resolution of the spectrograph ∆E/E is less than 0.2%. Particles may be recorded either in nuclear emulsions or in an arr… more

Calibration of G.M. Counters For Direct Counting of Radon in the Atmosphere

Description: An experiment has been carried out for the direct calibration of a Geiger-counter immersed in a balloon containing a known concentration of radon in equilibrium with its daughters. A theory was developed for finding out the geometrical efficiency of the counter used in this way, and for checking the experimental results with theoretical efficiency. The counters calibrated in this way may be useful for the direct measurement of radon in uranium mines and may also be useful for monitoring radioac… more

Cesium-137 and Strontium-90 in Milk

Description: Cesium-137 and strontium-90 levels in liquid milk samples from Bombay and 27 other stations in India, and powder milk samples from Australia, Denmark, Holland, India, U.K. and U.S.A/ have been estimated. The results of these measurements have been interpreted on the basis of the total injection of these isotopes in the atmosphere, their rate of fallout, and seasonal effects.

Coolball, a Machine Code for Thermal Analysis of Pebble Bed Reactor Cores

Description: COOLBALL is an IBM 650 machine program designed to calculate local gas and ball temperatures, gas flow, and pressure loses as induced by non-uniform power generation and voidage within an axial flow Pebble Bed Reactor core. This code has been used extensively to study the thermal characteristics of Pebble Bed Reactor cores in support of a broad program for the development of the PBR concept.

The Decontamination and Recovery of Precious Metals

Description: "This report is the third quarterly report under Contract AT(30-1)-2528 for the decontamination and recovery of precious metals from contaminated scrap. The results described in [2nd quarterly report] and expanded in this report confirm the statement that the method achieves not only the desired decontamination but also produces a product of high purity. In addition the relative simplicity of the method makes it particularly adaptable to large scale manipulation."

Detection and Identification of a Ruptured Fuel Element at the SM-1 (APPR-1) Nuclear Power Plant

Description: Summary. In October 1960, increases in the fission product activity of the primary coolant of the SM-1 power plant indicated that a fuel element failure had occurred. Low power tests were run first to determine the nature and magnitude of the defect. Flux tilting experiments were then performed to determine the general location of the failed element. Finally, the primary coolant flowing through each of the fuel elements was sampled at low reactor power for relative iodine activity to determi… more

Determination of Particle Size Distribution by X-Ray Absorption

Description: "As it is frequently necessary to know the distribution of particle sizes in various products used in industrial applications, a number of means have been devised for these determinations. Some of them include direct microscopic measurement, screening of product, extraction of samples from a settling slurry as with the Andreasen pipette, air and liquid elutriation, adsorption of gases and liquids, and light absorption."

Experiments and Analysis for SM-1 Core II With Special Components

Description: Abstract: This technical report contains a summary of analytical and experimental work performed on SM-1 Core II, with special components is presented. The effects of these special assemblies upon power distribution and core reactivity were calculated and compared to experimental measurements. A thermal analysis was conducted to determine steady state and transient performance of the special test components of the core as well as some of the hotter standard Core II components. Experimental work… more

Fluoroscopic Crystal Investigation

Description: "An investigation was carried out on the possibility of increasing the light output of single crystals by applying an electric field throughout the crystal lattice. Pulses of frequency 2.5 x 10/sup 5/ cps were used with a voltage gradient of 10/sup 4/ volts/cm, and gamma radiation from Cs/sup 1//sup 3// sup 7/ and Co/sup 6//sup 0/ was used to excite the crystals. Tests were run on many types of scintillators. The visible light output was found to be increased by electric pulses for many of the … more

Fuel Element Development Program for the Pebble Bed Reactor

Description: Previous results from the Pebble Bed Reactor Fuel Element Development Program had shown the excellent promise of vapor-deposited Al2O3 doq5intw on UO2 particles as a low permeability high temperature fission product barrier. However, since the matrix material for the PBR fuel element is a graphite sphere, carbonaceous coatings on the dispersed fuel particles might be of more interest because of improved particle coating-matrix compatibility and no displacement of neutron moderating materials. … more
