Relevant terminology

In the context of a future FMCT, referring to “fissile material” without adding qualifications could result in misunderstandings and potential loopholes stemming from the term’s different technical definitions. Although “fissile material” is commonly understood to include substances that chain-react with slow neutrons (i.e., fuel used in power reactors), it also may refer to materials that can chain-react with fast neutrons in a weapon. Because a future FMCT would not prohibit the production of “fissile material” for non-military uses, any future treaty will require an agreed definition that is limited to nuclear materials capable of chain-reacting for the purpose of a nuclear weapon or other nuclear explosive device.
