Beneficial Uses of Nuclear Byproducts/Sewage Sludge Irradiation Project. Progress Report, January-June 1983

摘要

Sandia technical and engineering support for DOE's Byproduct Utilization Program (BUP) continued. A purchase order was placed for a prototype sludge solar dryer with Intermountain Wholesale, Inc. (IMCO) of Denver, Colorado. Gamma irradiation of various commodities in the Sandia Irradiator for Dried Sewage Solids (SIDSS) and in the Gamma Irradiation Facility (GIF) continued. Several tons of sludge were irradiated for a sludge stockpile experiment, and 2 tons of sludge have been irradiated for the NMSU Department of Crop and Soil Sciences. SIDSS upgrading has included the installation of new limit switches, vacuum pumps, speed controls, and elapsed time indicators. Routine and preventive maintenance has included swipe tests and lubrication of the conveyor bearings. A sludge stockpile experiment was initiated. All microbiological analyses are being done by the NMSU Department of Biology, and temperature measurements and sample handling and shipping are being done by SNLA. Sewage Solids Irradiation Transport System (SSITS) cask activities included placement of a contract for final machining of the two cask bodies. Analyses of cask performance when loaded with six strontium-90 (Sr-90) capsules were done. (ERA citation 10:011008)
