Investigation of early oxide-layer formation has been done using the neutron reflectometer, i.e., SUIREN (apparatus for Surface and Interface investigations with Reflection of Neutrons), at the nuclear reactor research JRR-3 of JAEA. The tested materials were pre-oxidized, solution-annealed, JPCA steel specimens. Two types of early oxide layers were investigated, i.e., oxidation in air at 900C for 1 minute and oxidation in air at 450C for 75 hours. The results showed that the neutron reflectometer was able to detect the early formation of oxide layers.
