The development of small reactors in the global has been briefly introduced. The advantages and features of small reactors also have been analyzed. In view of the present situation of energy demand of Jiangxi province

the necessity and feasibility of small reactors development in Jiangxi province is analyzed by theoretical research. The research results indicate that small reactors technology is mature and the investment cost is lower

which can reduce the pressure of energy-saving and emission reduction in Jiangxi province and meet the diverse demand of energy

so the development prospect of small reactors is broad.
