Owing to the fast economic growing and the concern over greenhouse gases and air pollution,the development of nuclear energy is one important option to meet the expanded energy consumption in our future.To achieve that goal,continuing and reliable supplies of uranium are critical to future nuclear power projects.As is well known,global terrestrial reserves of uranium are limited and the deposits in China are relatively small.Given the projected big growth in nuclear power in the future,reliable supply of uranium at a reasonable price is essential for China.Extraction of uranium from seawater faces a great challenge but has received attention for more than sixty years.It is described by American scientists recently as a "game-changing" approach if it can be realized at economic viable costs.Encouraged by the global aggressive nuclear power development plans in the past years,although the pace was slow down by Fukushima accident in Japan in 2011,extraction of uranium from seawater has been emerging as a potential approach to overcome the shortage of nuclear fuel.
