JAERl is conducting nuclear safety research primarily at the Nuclear Safety Research Center in close cooperation with the related departments in accordance with the Annual Plan for Nuclear Safety Research issued by the Nuclear Safety Commission. The fields of conducting safety research at JAERl are the engineering safety of nuclear power plants and nuclear fuel cycle facilities, and radioactive waste management as well as advanced technology for safety improvement or assessment. This report summarizes the nuclear safety research activities of JAERI from April 2001 through March 2003.

The inevitable increases of food production and energy consumption with an increase in world population become main causes of an increase of nitrate load to the environment. Although nitrogen is essential for the growth of animal and plant as a constituent element of protein, excessive nitrate load to the environment contaminates groundwater resources used as drinking water and leads to seriously adverse effects on the health of man and livestock. In order to clarify the problem of nitrate contamination of groundwater and search a new trend of technology development from the viewpoint of environmental remediation and protection, the present paper has reviewed adverse effects of nitrate on human health, the actual state of nitrogen cycle, several kinds of nitrate sources, treatment methods for reducing nitrate level, etc.

Selenium oxyanions; Highly selective uptake by a novel anion exchanger

Kozai, Naofumi; Onuki, Toshihiko; Komarneni, S.*

Journal of Materials Chemistry, 17(12), p.2993 - 2996, 2002/12

Here we report the extremely high and selective uptake of selenium oxyanions by a novel exchanger, NiZn(OH)(OCOCH)・nHO that has brucite-type hydroxide layers with OCOCH anions in the interlayers. This Ni-Zn basic salt exhibited very high selectivity for Se(IV) (Kd = 9.0x10 ml/g with an initial Se(IV) concentration of 1x10 M) in the presence of 0.1M Cl solution while the well known anionic clay, MgAl(OH)NO・nHO showed a Kd of 6.0x10 ml/g under the same conditions. The uptake of Se(IV) on the Ni-Zn basic salt was found to be irreversible when treated with solutions containing 1N Cl, 1N NO, or 1N PO, while the Se(IV) sorbed on anionic clay was easily desorbed in a 1M Cl solution. This novel exchanger also showed high Kd (2.610 ml/g at an initial Se concentration of 110 M) for Se(VI) and therefore it is expected to be useful for decontamination and removal of selenium oxyanions from contaminated water.
