FY97 Status Report on the HSV and Titanium Tritide Samples

Description: The HSV in storage in MTF has been monitored, and the gas sampled and analyzed. The net conclusion is that no significant He evolution has occurred to date, and thus the HSV is performing as expected. The annual resorption isotherms have been recorded on a titanium tritide sample with 582 total days tritium exposure, and no significant effects have been noted. A gas sample was also taken from the test cell and analyzed.

An historic global SO2 emissions inventory for climate detection studies FY97 report to NOAA

Description: It has become apparent that anthropogenic aerosols exert radiative influence on the climate. This influence is comparable in magnitude but opposite in sign to that of greenhouse gases. The modeling effort here at LLNL has been designed to provide data and information for climate detection studies in order to help understand the role of anthropogenic aerosols over the interannual and decadal time scales.

Organic tanks safety program, FY97 waste aging studies. Revision 1

Description: To model tank waste aging and interpret tank waste speciation results, the authors began measuring the reactivity of organic complexants and related compounds towards radiation-induced oxidation reactions. Because of the high efficiency of scavenging of the primary radicals of water radiolysis by nitrate and nitrite ion, the major radiolytically-generated radicals in these solutions, and in Hanford tank wastes, are NO{sub 2}, NO and O{sup {minus}}. Prior to this effort, little quantitative info… more

Science of NIF scale capsule development (activities for FY97)

Description: The focus of this work is the production of 2-mm P{alpha}MS mandrels by microencapsulation for use as National Ignition Facility (NIF) laser targets. It is our findings thus far that the processing techniques used previously for the 0.5-mm and 1.0-mm targets are no longer useful for preparation of the larger targets for a few fundamental reasons. The driving force for sphericity (from the minimization of interracial energy) decreases as the radius of curvature increases. Simultaneously, the mec… more

FY-97 operations of the pilot-scale glass melter to vitrify simulated ICPP high activity sodium-bearing waste

Description: A 3.5 liter refractory-lined joule-heated glass melter was built to test the applicability of electric melting to vitrify simulated high activity waste (HAW). The HAW streams result from dissolution and separation of Idaho Chemical Processing Plant (ICPP) calcines and/or radioactive liquid waste. Pilot scale melter operations will establish selection criteria needed to evaluate the application of joule heating to immobilize ICPP high activity waste streams. The melter was fabricated with K-3 re… more
