Scope
This standard specifies the method outline, standard samples, equipment and devices, measurement environmental conditions, and measurement steps for measuring the thickness of the graphite coating on the inner wall of the fuel element cladding tube and the thickness of the beryllium coating on the support pad base and the side of the isolation block in heavy water reactor nuclear power plants.
This standard is applicable to the measurement of the thickness of the graphite coating on the inner wall of the fuel element cladding tube and the thickness of the beryllium coating on the support pad base and the side of the isolation block in heavy water reactor nuclear power plants, with a measurable range of (0~30) μm.
