[en] The declines of nuclear power in many developed and developing countries are analyzed and the reasons are traced back to their historical origins. The major weakness of current power reactor designs is identified, the negligence of inherent safety features leads to over-redundancy of systems which in turn resulted in hyge economic size, large investment, and long lead time. Various advanced power reactor designs of the second generation are compared comprehensively, compared and the technical line of power reactor development for PRC is proposed
