Lead-bismut Eutectics Cooled Long-life Safe Simple Small Portable Proliferation Resistant Reactor (lspr)

Conventional nuclear power reactors have almost reached a power size limit after pursuing the economies of scale by building larger plants. Future directions in which nuclear power can be effectively developed are unlikely to be toward larger sizes. Currently it is almost impossible to find new sites for larger plants in the developed countries; larger plants also pose a large economic risk that might be unbearable even for large companies or governments.
