Accidental Dispersion of Reactor Poisons and the Controlled Distance Required

Description: Two types of hypothetical reactor catastrophe are considered. In the first of these, the Boiling Accident,'' it is assumed that a fraction of the radioactive material in a reactor is released to the atmosphere at a steady rate over a period of hours. In the second, the Puff Accident,'' it is assumed that the release of the radioactive material takes place instantaneously.'' The following concepts are used as measures of the hazard existing outside the controlled plant area. Danger Distance,'' d… more

On the Analysis of Bubble Chamber Tracks

Description: Since its invention by Glaser in 1953, the bubble chamber has become a most valuable tool in high-energy physics. It combines a number of advantages of various older methods of particle detection: it offers high spatial resolution, rapid accumulation of data, some time resolution, and some choice of the nucleus whose interaction one wants to study (bubble chambers have been made to operate with a large number of different liquids, including H{sub 2}, D{sub 2}, He, Xe, and several hydrocarbons).… more

Laboratory Method for Adjusting Hydrogen Content of Zirconium

Description: A new method of introducing predetermined quantities of hydrogen into zirconium was developed and evaluated. The procedure is simple, effective, and inherently good in preverting oxygen and nitrogen contamination. Zirconium samples containing four levels of dissolved hydrogenated to 100, 300, 3500, and 7700 ppm hydrogen. Dissolved oxygen was found to decrease hydrogen absorption in both the alpha and beta modifications of zirconium. The effect of hydrogen on density, hardness, and microstructur… more

FLUX-TRAP REACTOR WITH ABSORBER IN THE CENTER

Description: An idealized flux-trap reactor is modified by the insertion of absorber. It is shown that, for appreciable absorption, a flux depression results, and the remaining flux is proportional to the diffusion constant D times the center flux in the nonabsorption case. This factor D just cancels the factor 1/D in the expression for this center flux so that the flux in the case with absorber is independent of D. In the case with absorber the advantage of Be and BeO largely disappears. (auth)

HYDROGEN AND OXYGEN ISOTOPES APPLIED TO THE STUDY OF WATER-METAL REACTIONS. EXCHANGE OF D$sub 2$O$sup 18$ WITH ALPHA ALUMINA MONOHYDRATE

Description: Isotopes of hydrogen and oxygen may be useful in elucidating the mechanism of aqueous corrosion reactions, in which an important step may be diffusion of protons and/or hydroxyl for oxide) ions through a thin protective film. The technique of isotope exchange and the kinetic isotope effect both appear applicable. For the reaction between water and aluminum, the product (above 90 deg C) is alpha -alumina monohydrate ( alpha -AlCDH). The exchange of D/sub 2/O/sup 18/ with alpha -AlOOH (sub-micron… more

HYDROGEN REDISTRIBUTION IN THIN PLATES OF ZIRCONIUM UNDER LARGE THERMAL GRADIENTS

Description: By using experimental data, the quantities determimng the extent of dissolved H redistribution under a thermal gradient in Zircaloy were calculated. It is concluded that the phenomenon of hydride precipitation by means of thermaI gradient diffusion of dissolved H in Zircaloy fuel plates and cladding places much more severe restrictions on the allowable pre-operation H content of such elements than was hitherto suspected. The specific effects of operating conditions on H content of plates and cl… more
