<p>The tube (14) is partially immersed in a surrounding medium (M) and is heated internally. The electrode potential of the tube is measured relative to a reference electrode (54). From the measured data, corrosion properties of the tube are assessed. The chemical composition of the medium is made similar or identical to that of the coolant in a nuclear reactor. The aqueous medium contains dissolved gases existing or arising during nuclear reactor operation. Pressure, temperature and flow are similarly adjusted to simulate operating conditions of a tube in the reactor pressure vessel. The tube contains an internal heater (40). Its power is adjusted to match that dissipated from nuclear fuel within a tube, during nuclear reactor operation. An independent claim is included for a corresponding apparatus.</p> |
