Preparation of autoclave specimens and fabrication of the holders were completed. Tensile test and straindeflection measurements were performed on the autoclave materials. In autoclave testing, a total of nine runs was completed during the quarter. Several methods of descaling the exposed specimens for weight loss determination are still under investigation, and no quantitative post- test evaluation was initiated. Qualitative examination showed that coupcns tested in the vapor phase evidenced greater attack than those in the liquid phase. Other findings indicate that the most active environmental agent is oxygen, the agent used to adjust pH, whether phosphate or hydroxide, has no differential effect, and the magnitude of corrosion is very low (a few milligrams). Final engineering design for the corrosion loop modifications was completed. All of the major modifications were also completed, except for installation of the second independent mcdel secondary system. In addition, final electrical wiring, hydrostatic testing and thermal insulation remain to be done. Rework of the Inconel miniature vessels and the bimetal mcdel vessels was completed. Fabrication was complete, except for final assembly of the Inconel model vessels and the bimetal miniature vessels. Fabrication of detail parts for the Monel and nickel miniature vessels was initiated. (For preceding period see MND-E-2009.) (auth)
