Corrosion study of candidate APT engineering materials
- Los Alamos National Lab., NM (United States)
The anticipated needs for tritium have called for an analysis of proton accelerator technologies (APT) as an alternative to reactor production. To produce tritium with an accelerator, a neutron spallation target is bombarded with high energy protons (800-1200 MeV). To minimize its temperature and to provide a neutron moderator, the spallation target is immersed in a cooling water loop. Initially the water in the loop is distilled and deionized, but with irradiation radiolysis products are formed. The most stable species is hydrogen peroxide (H2O2) which is a long lived radiolysis product and is formed from the combination of two OH radicals. In this poster we describe our current progress to measure the corrosion rates of candidate APT materials in the laboratory to simulate the effects of radiological environments (such as effects of pH, hydrogen peroxide, temperature, metal-chlorides, and flowrates). Future efforts for control and monitoring of corrosion rates of these materials at the Los Alamos LANSCE facility will also be presented.
