<p>PROBLEM TO BE SOLVED: To estimate the corrosion of a structural material in contact with an acidic solution in a plant for processing the acidic solution, particularly, in a spent nuclear fuel reprocessing facility. SOLUTION: The product of corrosion speed in atmospheric boiling state, corrosion acceleration of dissolved chemical species, welding influence correction value, temperature correction value, and operation mode correction value is estimated as the corrosion speed in a plant to be diagnosed. This diagnostic system comprises estimating the corrosion speed and corrosion state by use of material information 1, operation information 3 and medium information 5, and outputting the result of estimation.</p> |
