The first series of autoclave test runs was completed. The corrosion product film was removed from all test specimens by immersing in a boiling 25% sulfamic acid bath for l hr. Weight loss determinations were made for all specimens and a summary of the results is included; 576 were used. Statistical analysis of the weight loss data was started. Microscopic examination of the autoclave test specimens revealed no cracking or pitting. Corrosion loop modiflcations were completed. Hydrostatic tests of the loop and functional tests of the power equipment were successfully completed. All loop controls were checked out. It was necessary to use 5% sulfamic acid solution to clean the loop prior to testing. The primary loop was successfully cleaned in this manner. During pressurization of the primary loop, in preparation for cleaning the secondary systems, the pressurizer-heater burned out. A new heater assembly was ordered. In the interim period, argon gas pressurization will be attempted. Fabrication of the following vessels was completed: MOD SG-7 and SH-7 (Inconel), MIN-15 and -16 (bimetal), MIN-l2, -13, and -14 (Monel) and MlN-17, -18, and -19 (nickel), Welding specifications for Inconel, Monel, and nickel are near completion.
