Subsurface marker emplacement test plan

Description: Current plans propose placing subsurface markers within protective barriers to deter potential human intrusion into disposed radioactive wastes. The subsurface markers would provide warning to the digging intruder should surface markers be removed, destroyed, or ignored. This plan sets forth procedures for testing the survivability of the subsurface markers during construction of the barrier. After the tests described herein are concluded, a decision can be made as to whether subsurface markers… more

RADIATION EFFECTS ON EPOXY CARBON FIBER COMPOSITE

Description: Carbon fiber-reinforced bisphenol-A epoxy matrix composite was evaluated for gamma radiation resistance. The composite was exposed to total gamma doses of 50, 100, and 200 Mrad. Irradiated and baseline samples were tested for tensile strength, hardness and evaluated using FTIR (Fourier transform infrared) spectroscopy and DSC (differential scanning calorimetry) for structural changes. Scanning electron microscopy was used to evaluate microstructural behavior. Mechanical testing of the composite… more

Effects of oxygen cover gas and NaOH dilution on gas generation in tank 241-SY-101 waste

Description: Laboratory studies are reported of gas generation in heated waste from tank 241-SY-101. The rates of gas generation and the compositions of product gas were measured. Three types of tests are compared. The tests use: undiluted waste, waste diluted by a 54% addition of 2.5 M NaOH, and undiluted waste with a reactive cover gas of 30% Oxygen in He. The gas generation rate is reduced by dilution, increased by higher temperatures (which determines activation energies), and increased by reactions of … more

Research and development of a phosphoric acid fuel cell/battery power source integrated in a test-bed bus. Final report

Description: This project, the research and development of a phosphoric acid fuel cell/battery power source integrated into test-bed buses, began as a multi-phase U.S. Department of Energy (DOE) project in 1989. Phase I had a goal of developing two competing half-scale (25 kW) brassboard phosphoric acid fuel cell systems. An air-cooled and a liquid-cooled fuel cell system were developed and tested to verify the concept of using a fuel cell and a battery in a hybrid configuration wherein the fuel cell suppli… more
