Abstract
In order to evaluate the corrosion of stainless steel in spent nuclear fuel reprocessing solution facilities, immersion tests and polarization measurements of R-SUS304ULC stainless steel in nitric acid solutions containing neptunium-237, a radionuclide, were conducted. We have clarified the difference from that in pure nitric acid solution and discussed the possibility of calculating the corrosion amount from electrochemical measurements.
