Description

This report presents the results of a corrosion study in which coupons were exposed in the Brazilian TRIGA IPR-R1 research reactor for 3 years. Three racks with horizontal coupons were immersed in the reactor pool in 2002; a rack with vertical coupons and a sediment collector were also immersed in the reactor pool in 2005. Even though the reactor coolant (water) is considered to be good, almost all the coupons pitted to varying extents. The presence of sediments and poor circulation of water in the vicinity of the racks probably caused the coupons to pit. Aluminium alloy AA 1050 pitted more than the other alloys. (author)
