Available in PDF, EPUB and Kindle. Book excerpt: Tank 241-SY-101 is a double shell, high-level waste tank located in the 200 West Area of the Hanford Site. This tank contains about 1 million gallons of waste that was concentrated at the 242-S Evaporator. Shortly after the waste was put in the tank, the waste began to expand because the generation of gases. In 1990 this tank was declared to have an unreviewed safety question because of the periodic release of hydrogen and nitrous oxide. A safety program was established to conduct a characterization of the waste and vented gases and to determine an effective means to prevent the accumulation of flammable gases in the tank dome space and ventilation system. Results of the expanded characterization conducted in fiscal year 1991 are presented. The use of gas chromatographs, mass spectrometers, and hydrogen-specific monitors provided a greater understanding of the vented gases. Additional instrumentation placed in the tank also helped to provide more detailed information on tank temperatures, gas pressure, and gas flow rates. An extensive laboratory study involving the Westinghouse Hanford Company, Pacific Northwest Laboratory, Argonne National Laboratory, and the Georgia Institute of Technology was initiated for the purpose of determining the mechanisms responsible for the generation of various gases. These studies evaluate both radiolytic and thermochemical processes. Results of the first series of experiments are described.

Available in PDF, EPUB and Kindle. Book excerpt: The mixing of wastes at Hanford over the years has led to several safety concerns. These safety concerns fall into six categories: wastes that generate flammable gasses or gas mixtures; wastes that contain high concentrations of ferrocyanides or tanks suspected of containing large amounts of ferrocyanides; wastes that contain greater than 3 wt % total organic carbon; wastes from which toxic or noxious vapors are suspected of emanating; wastes that contain high radiolytic heat; and wastes that may contain sufficient fissile material to pose a criticality concern. This report addresses the chemistry associated with the generation of flammable gases.

Available in PDF, EPUB and Kindle. Book excerpt: Volume growth of contents in a waste storage tank at Hanford is accompanied by episodic releases of gas and a rise in the level of tank contents. A theory is presented to describe how the gas is retained in the waste and how it is released. The theory postulates that somewhat cohesive gobs of sludge rise from the lower regions of the tank and buoyancy overcomes the cohesive strength of the slurry; this quantitatively explains several of the measured phenomena and qualitatively explains other observations.

Book excerpt: This paper addresses certain safety issues associated with the Hanford Tank 241-SY 101 hydrogen mitigation mixing test. Specifically, the study, is concerned with the effect of pump shearing, jet mixing, and piling-up on the following areas: Gas generation; gas retention; gas release (immediate); gas release (long-term); and saltcake. The findings for each issue area of concern are addressed.

Available in PDF, EPUB and Kindle. Book excerpt: Rheological characterization and small scale simulation of Hanford Tank 241-SY-101 has been initiated to aid in the remediation efforts for the Department of Energy Hanford Site. The study has been initiated in response to growing concerns about the potential flammability hazard pertaining to the periodic release of up to 10,000 cubic feet of hydrogen, nitrous oxide, nitrogen, and ammonia gases. Various stimulants emulating the radioactive waste stored in this tank have been used to ascertain the rheological parameters of the waste, simulate the ongoing processes of gas generation and release phenomenon inside the tank, and determine the feasibility of jet mixing to achieve a controlled release of the gas mixture.
