Concern has been expressed that IRFNA procured from different sources of supply, and hence containing different levels of water, HF, dissolved solids, etc., may produce varying rates of corrosion of storage tank alloys. In order to assess the effects of these variables upon the corrosion rate of aluminum alloy in IRFNA, four pairs of electrochemical cells of the bottom working electrode type, machined from 3L65 alloy and containing working electrodes cut from SN5144 oxidiser tank wall section, were constructed. The SN5144 oxidiser tank wall section used for the fabrication of these working electrodes was selected arbitrarily, i.e. without recognition of the left hand LH or right hand RH designation used previously, since no significant difference in corrosion behaviour was observed for such LH or RH samples in the previous studies.
