Abstract

Abstract

The pool bottom and wall of the 49-2 swimming pool reactor are made of pure aluminum. In order to grasp the actual state and changes of the defects at the pool bottom and ensure the safe and stable operation of the reactor, based on the information of the pool bottom, the medium in the pool, the material of the pool wall, etc., the pitting corrosion environment of the point defects at the pool bottom was simulated, and the experimental research on the measurement of aluminum corrosion rate at the pool bottom under extreme working conditions was carried out. The maximum corrosion rate of the aluminum at the point defects is 0.0326 mm/a, which provides technical data for the integrity assessment of the bottom of the reactor.
