The construction of a remote Raman microscope system with a variable microscope‐to‐spectrometer distance of up to 3 m is described. Oxidative surface corrosion products on zirconium alloy and stainless‐steel nuclear fuel claddings for pressurized water and advanced gas cooled reactor systems produced under various conditions were studied and the potential of the technique for in situ analysis is discussed. Under the conditions studied experimentally, the major corrosion products are found to be α‐ZrO 2 and α‐Fe 2 O 3 for the zirconium alloy and stainless‐steel claddings, respectively.
