Physical properties of Hanford metal waste

Description: The Hanford metal wastes were divided into four categories: supernate - the liquid waste; hard sludge - dense agglomerates of poorly defined crystalline carbonates approximating the hardness of soft blackboard chalk; soft sludge - an easily slurried semi-solid consisting chiefly of needle-like phosphates; and recombined sludge - a representative sample of the solid wastes as received from Hanford, shown to be a mixture of hard and soft sludges in the ratio 2/3 by weight. The density of supernat… more

The New Element Californium (Atomic Number 98)

Description: Definite identification has been made of an isotope of the element with atomic number 98 through the irradiation of Cm{sup 242} with about 35-Mev helium ions in the Berkeley Crocker Laboratory 60-inch cyclotron. The isotope which has been identified has an observed half-life of about 45 minutes and is thought to have the mass number 244. The observed mode of decay of 98{sup 244} is through the emission of alpha-particles, with energy of about 7.1 Mev, which agrees with predictions. Other consid… more

THE CHOICE OF THE PROPER REFRACTORY FOR THE CASTING OF HIGHMELTING ELECTROPOSITIVE METALS

Description: As titanium, zirconium, and other of the high melting electropositive metals become more important, the problem of using suitable refractory materials for their casting becomes more important. This paper discusses the method of choosing and testing possible container materials. To make the discussion more specific, titanium is used as an example. As titanium melt at 2000 {+-} 10 K, it is immediately clear that one is restricted to refractory materials melting considerably above 2000 K. This gre… more

A rapid, simple method for the determination of the radon content of water

Description: The historical approach to the separation of radon from water is liberation of the radon from the sample by boiling under vacuum in the presence of a strong acid; flushing the liberated radon, with an inert gas, into an ionization chamber or an alpha proportional counters and measuring the collected activity. Such an analysis requires a manipulation time of approximately one hour, a waiting period of two to three hours before measurement to allow transitory equilibrium to be reached, and finall… more

P-10 stack monitoring

Description: On June 14, 1950, an aluminum Kanne Chamber on the 108-B vacuum discharge line was placed in operation. The vacuum pump discharge line chamber has a very poor reputation for two reasons: 1. An apparent hysteresis effect which shows as a high reading after a slug of gas has passed through it, and 2. Failure to return to background current. Cause of the hysteresis effect may be the distribution of tritium in the vacuum pump discharge gas. The rate of gas flow through the Kanne chamber is approxim… more
