Abstract

ABSTRACTCopper is being considered as a possible container material for the disposal of nuclear fuel waste in Canada. The mechanism of the uniform corrosion of copper is being investigated in aerated 1 mol·dm-3 NaCl and under simulated disposal conditions. In NaCl solution, the rate of corrosion of a copper rotating disc electrode (RDE) is controlled partly by the rate of transport of copper complex ions away from the electrode surface. Similarly, under simulated disposal conditions, the rate of corrosion may be controlled by the transport of copper through compacted buffer material. However, longer-term results are needed to prove this latter statement.
