Abstract:

The first series of three 2000-hr autoclave tests on Monel and nickel coupons was completed. In one autoclave, charged with water containing 1000-ppm chloride and 15-ppm oxygen, the Monel coupon in the vapor phase experienced mild pitting. Average corrosion rates were for Monel, 0.51 mdd and for nickel, 0. 37 mdd milligrams per square decimeter per day. A 2000-hr autoclave test on nickel, under conditions which caused pitting of Monel, was initiated. The corrosion loop operated virtually continuously during the quarter. Average operating time efficiency OTE was approximately 84. The only major shutdown was caused by failure of terminals on one of the primary 50-kw line heaters. Testing of the bimetal model vessels MOD SX-4 and the Inconel model vessels MOD SX-7 continued. Testing of the bimetal miniature vessels MIN 15 and 16 and the Inconel miniature vessels MIN 10 and 11 continued. Analysis of heat transfer data was started. Preliminary results for the model vessels indicate that large effects on heat transfer due to scaling have not occurred.
