CORROSION OF STAINLESS STEEL AND TITANIUM IN PUREX 2WW

Technical Report ·
OSTI ID:4324240
Heat-transfer corrosion rate data are presented which compare the resistance of three types of stainless steel and one type of titanium to corrosion by boiling synthctic Purex 2WW. Specific corrosion parameters investigated were time and temperature. Laboratory and mock-up data had the same order of magnitude. Pilot plant data are presented which illustrate some aspects of the nature of corrosion on heat-transfer surfaces as affectcd by material composition and method of fabriciation. Types 304-L, 347, and 312 stainless steel were tested in the annealed, sensitized, or as-welded condition, and type A- 70 titanium was tested in the annealed condition. Their corrosion rates were linear with time after an induction period, and, with two exceptions, were linear with temperature. At one thousand hours of exposure and a metal temperature of 145 deg C, sensitized type 347 had a corrosion rate of about fifty-seven mils per year, sensitized 304-L-about thirty-nine mils per year, sensitized 312--about thirty-three mils per year, and annealed A-70 titanium--about three mils per year.
