Deuterium retention in porous vacuum plasma-sprayed tungsten coating exposed to low-energy, high-flux pure and helium-seeded D plasma

Alimov, V.; Tyburska, B.*; Ogorodnikova, O. V.*; Roth, J.*; Isobe, Kanetsugu; Yamanishi, Toshihiko

Deuterium retention in porous vacuum plasma spraying tungsten coating exposed at various temperatures to a low-energy, high flux (10$$^{22}$$ D/m$$^{2}$$s) pure D and helium-seeded D plasmas was examined by thermal desorption spectroscopy and the nuclear reaction. Under exposure to pure D plasma (76 eV D$$_{2}$$$$^{+}$$) at 340-560 K, the D concentration reaches 1$$sim$$2 at.% at depths of several micrometers, while at temperatures above 700 K the D concentration is below 10$$^{-2}$$ at.% and deuterium is retained over the whole thickness of the coating. Seeding of 76 eV He$$^{+}$$ into the D plasma reduces the D retention at temperatures of 400-600 K. However, at temperature above 700 K, the D retention becomes comparable to that for pure D plasma exposure.

Effect of Al$$_{2}$$O$$_{3}$$ nanoparticles on radiolytic H$$_{2}$$O$$_{2}$$ production in water

Hydrogen peroxide, H$$_{2}$$O$$_{2}$$, is the major stable oxidizing species produced in the radiolysis of water and understanding the mechanisms involved in its production is important both from a fundamental science perspective and for engineering purposes, in particular within the nuclear power industry. In this work, the yields of H$$_{2}$$O$$_{2}$$ were determined in aqueous slurries in the pH range of 1-13 with various amounts of added Al$$_{2}$$O$$_{3}$$ nanoparticles. The addition of Al$$_{2}$$O$$_{3}$$ generally decreased H$$_{2}$$O$$_{2}$$ yields at all pH values within this range in the $$gamma$$ radiolysis of both deaerated and aerated slurries, except at very high pH. Very little effect of pH was observed in the $$gamma$$ radiolysis of deaerated systems in the pH range of 3-8, whereas a large increase in H$$_{2}$$O$$_{2}$$ yields was observed in aerated Al$$_{2}$$O$$_{3}$$ slurries at the extreme pH values. Scavenger capacity studies using methanol as an OH radical scavenger show that the decrease in H$$_{2}$$O$$_{2}$$ yields with added Al$$_{2}$$O$$_{3}$$ occurs at relatively long time scales and is probably due to reaction of the solid nanoparticles with OH radicals.
