Advanced ORIENT cycle study (Phase I), 5; Metal corrosion evaluation in hydrochloric acid media

Koyama, Shinichi; Ozawa, Masaki; Kurosawa, Kiyoko*; Hanamoto, Yukio*; Tatenuma, Katsuyoshi*

no journal, , 

Corrosion experiments (Immersion, exposure and electro chemistry) in pure HCl and HCl type SHLLW solution at RT and 90$$^{circ}$$C were performed using selected candidate metals, Ta, Zr, Nb and Hastelloy-B. We found the measured corrosion rates were less than 0.05 mm/y for Ta in all experiment, and therefore, Ta showed an all-round anti-corrosion property. Hastelloy-B, Nb and Zr were not acceptable at 90$$^{circ}$$C because of its relatively high corrosion rate ($$>$$0.1 mm/y).

Metal corrosion evaluation in hydrochloric acid media on tertiary pyridine-type resin applying to fuel reprocessing system, 5; Corrosion evaluation of Ti-0.15Pd and Ta-lining metals in hydrochloric acid media

Koyama, Shinichi; Ozawa, Masaki*; Fujii, Yasuhiko; Kurosawa, Kiyoko*; Hanamoto, Yukio*; Tatenuma, Katsuyoshi*; Suzuki, Tatsuya*

no journal, , 

In order to develop a separation process using tetriary pyridine-type resin, Ti-0.5Ps, Ta-lining Ti-0.15Pd and Ta-lining hastelloy-B were selected as candidate materials toward HCl solution used as solvent in this system. Immersion test in 12M pure HCl solution at RT was carried out. And immersion test, exposure test and electrochemical measurement in 7M HLLW-simulated HCl solution at RT and 90 deg. C were performed. As a result, all the materials show anti-corrosive property at the corrosion rate less than 1mm/y, except for Ti-0.5Pd in 12M pure HCl condition.

Metal corrosion evaluation in hydrochloric acid media on tertiary pyridine-type resin applying to fuel reprocessing system, 6; Influence of $$gamma$$-ray irradiation to hydrochloric acid corrosion of Ta and Hastelloy-B

no journal, , 

Corrosion experiment for Ta and Hastelloy-B was performed by $$gamma$$-ray irradiation under co-existence system of tertiary pyridine type resin and HCl media. As a result, Ta showed perfect anti-corrosion property under all experimental conditions. On the other hand, it was clear that the corrosion rate of Hastelloy-B was proportion to $$gamma$$-ray intensity. It is expected that oxidative species, such as hydrogen peroxide and ozone, were produced by irradiation, and were affected to corrosion.
