Program RELAX: A code designed to calculate atomic relaxation spectra of x-rays and electrons

Description: The code RELAX is designed to calculate atomic relaxation spectra of X-rays and electrons due to bound-bound transitions. This calculation is based on the atomic transition data contained in the Livermore Evaluated Atomic Data Library (EADL). The results produced by this code for fluorescence yield vs. atomic number (Z) have been published in Tables and Graphs of Atomic Subshell and Relaxation Data Derived from the LLNL Evaluated Atomic Data Library (EADL), z = 1--100{double prime}, UCRL-50400,… more

Elementary reaction rate measurements at high temperatures by tunable-laser flash-absorption

Description: The major objective of this program is to measure thermal rate coefficients and branching ratios of elementary reactions. To perform these measurements, we have constructed an ultrahigh-purity shock tube to generate temperatures between 1000 and 5500 K. The tunable-laser flash-absorption technique is used to measure the rate of change of the concentration of species which absorb below 50,000 cm{sup {minus}1} e.g.: OH, CH, and CH{sub 3}. This technique is being extended into the vacuum-ultraviol… more

Analysis of deposit from K-Reactor heat exchanger 4A

Description: Characterization of deposits from the reactor system provides a means of directly assessing corrosion and chemistry conditions within the system. The recent analysis of debris vacuumed from the bottom of K-Reactor tank provided information and reassurance about the conditions within the tank that would affect corrosion or moderator chemistry. Further opportunity for surveillance within the reactor system was recognized when solid deposits were found on the moderator side of the K-Reactor heat e… more

Behavior of mercury, lead, cesium, and uranyl ions on four SRS soils

Description: Samples of four Savannah River Site (SRS) soils were tested for sorption behavior with Hg[sup 2+], Pb[sup 2+], UO[sub 2][sup 2+], and Cs[sup +] ions. The purpose of the study was to determine the selectivity of the different soils for these ions alone and in the presence of the competing cations, H[sup +] and Ca[sup 2+]. Distribution constants, Kd's, for the test ions in various solutions have been determined for the four soils. In general, sorption by all of the soils appeared to be more compl… more

Selective flotation of fossil resin from western coal. A special report comprising: Monthly report for December 1991--April 1992 and Quarterly reports for December 1, 1991--February 29, 1992

Description: The test program has demonstrated that: (1) technically, the new flotation technologies discovered at the University of Utah and then improved upon by Advanced Processing Technologies, Inc. provide a highly efficient means to selectively recover fossil resin from coal. The proof-of-concept continuous flotation circuit resulted in fossil resin recovery with the same separation efficiency as was obtained from laboratory bench-scale testing (more than 80% recovery at about 80% concentrate grade); … more
