Factors Relevant to Utility Integration of Intermittent Renewable Technologies

Description: This study assesses factors that utilities must address when they integrate intermittent renewable technologies into their power-supply systems; it also reviews the literature in this area and has a bibliography containing more than 350 listings. Three topics are covered: (1) interface (hardware and design-related interconnection), (2) operability/stability, and (3) planning. This study finds that several commonly held perceptions regarding integration of intermittent renewable energy technolog… more

Los Alamos waste drum shufflers users manual

Description: This user manual describes the Los Alamos waste drum shufflers. The primary purpose of the instruments is to assay the mass of {sup 235}U (or other fissile materials) in drums of assorted waste. It can perform passive assays for isotopes that spontaneously emit neutrons or active assays using the shuffler technique as described on this manual.

High temperature alkali corrosion of ceramics in coal gas. Eighth quarterly progress report, June 1, 1993--September 1, 1993

Description: Gaseous alkali corrosion kinetics of Si{sub 3}N{sub 4} were investigated from 950 to 1100{degrees}C in an atmosphere containing 0.98 vol % sodium nitrate vapors. Linear reaction rates from 950 to 1100{degrees}C indicate that the alkali reaction Of Si{sub 3}N{sub 4} is interface-controlled with an activation energy of 199 kJ/mol. Rate controlling step of overall reaction appears to be the oxidation of Si{sub 3}N{sub 4} to SiO{sub 2}.An alkali reaction mechanism, involving a complex dissolution-o… more
