All of the Following Are Issues That Have Limited the Building

All of the following are issues that have limited the building of breeder nuclear reactors except:

A) a breeder reactor makes more fissionable fuel than it uses
B) a breeder reactor uses liquid sodium, a highly reactive metal, rather than water as a coolant posing more safety risks
C) a breeder nuclear fission use of plutonium as fuel is associated with plutonium use in nuclear weapons
D) public opposition, technical problems, and accidents
E) uranium, used for conventional nuclear fission, is more plentiful and cheaper than originally thought
