For the development of accelerator-driven transmutation system (ADS), measurement of nuclide production cross-sections in proton-induced reactions on $$^9$$Be, C, $$^{27}$$Al, $$^{45}$$Sc, and V have been performed. The measured data are compared with the calculations by the latest nuclear reaction models and with the nuclear data library to investigate the reproducibilities.

A new type of fibrous adsorbent with excess amidoxime groups was synthesized by radiation-induced graft polymerization. Glycidyl methacrylate (GMA) was first radiation-grafted on polyethylene-coated polypropylene nonwoven fabrics and chemically modified with 3,30-iminodipropionitrile [NH (-CH$$_{2}$$-CH$$_{2}$$-CN)$$_{2}$$] (IDPN), which was further reacted with hydroxylamine to obtain graft chains containing two amidoxime groups per graft repeating units. The adsorption properties of this new adsorbent for uranium (U), vanadium (V), lead (Pb), copper (Cu), and cobalt (Co) ions at low concentrations (3.3-1000 ppb).

Suppression of hydrogen absorption to V-4Cr-4Ti alloy by TiO$$_{2}$$/TiC coating

Hirohata, Yuko*; Motojima, Dai*; Hino, Tomoaki*; Sengoku, Seio

Titanium oxide film was coated on entire surface of a V-4Cr-4Ti alloy to reduce hydrogen absorption at low temperature region. The film consisted with a mixture of TiO2 and TiC. The content of TiO$$_{2}$$ was approximately 80%. The hydrogen absorption rate of Ti-oxide coated V-alloy largely decreased with increase of the film thickness. In the case of the film with a thickness of 0.5 micron, the absorption rate was fifty times smaller than that of non-coated V-alloy at the absorption temperature of 573 K.

Vanadium uptake and an effect of vanadium treatment on $$^{18}$$F-labeled water movement in a cowpea plant by positron emitting tracer imaging system (PETIS)

We present real time Vanadate (V$$^{5+}$$) uptake imaging in a cowpea plant by Positron Emitting Tracer Imaging System (PETIS). Vanadium-48 was produced by bombarding a Sc foil target with 50 MeV $$alpha$$-particles at Takasaki Ion accelerators for Advanced Radiation Application (TIARA) AVF cyclotron. Then $$^{48}$$V was added to the culture solution to investigate the V distribution in a cowpea plant. The real time uptake of the $$^{48}$$V was monitored by PETIS. We measured the distribution of $$^{48}$$V in a whole plant after 3, 6 and 20 hours of V treatment by Bio-imaging Analyzer System (BAS). After the 20 hour treatment, vanadate was detected at the up-ground part of the plant. To know the effect of V uptake on plant activity, $$^{18}$$F-labeled water uptake was analyzed by PETIS. When a cowpea plant was treated with V for 20 hours before $$^{18}$$F-labeled water uptake experiment, the total amount of $$^{18}$$F-labeled water absorption was drastically desreased. Results suggest the inhibition of water uptake was mainly caused by the vanadate already moved to the up-ground part of the plant.
