Definition of fissile in English: fissileadjective ˈfɪsʌɪl 1(of an atom or element) able to undergo nuclear fission. （原子或元素）可（核）裂变的 可裂变的同位素。 Example sentencesExamples - It resumed the production, and testing of uranium enrichment centrifuges that can make fissile material for nuclear reactors or weapons.
- Smuggling can potentially provide fissile material for nuclear weapons or a wider range of radioactive materials for use in ‘dirty bombs’.
- It also is the toxic and radioactive byproduct of enriched uranium, the fissile material in nuclear weapons.
- No natural reactors exist today, as the relative density of fissile uranium has now decayed below that needed for a sustainable reaction.
- As a general rule, however, the biggest hurdle for a would-be nuclear power is the acquisition of fissile material - enriched uranium or plutonium.
2(chiefly of rock) easily split. （尤指岩石）易裂的，可裂的 flat-bedded and very highly fissile shale 极易开裂的平层状页岩。 Example sentencesExamples - The fossiliferous horizons occur in greenish to greyish siltstones and brown to black fissile shales associated with mollusc shells.
- The shales are conspicuously fissile throughout the section and, along with the associated carbonates, tend to become increasingly red-colored toward the top of the member.
- The oil shales are very fissile, non-laminated, dark brown to black and have a bituminous smell, whereas the less carbonaceous beds are weakly fissile.
- This horizon, up to 1.3 m thick, is a black, highly fissile shale.
- For example, fissile slates tend to yield much flatter particles than massive granites.
Derivativesnoun fɪˈsɪlɪtifɪˈsɪlədi During compaction of siliciclastic muds the flaky clay particles are realigned to be parallel to each other and impart a fissility (a direction of easy splitting) to the rock, which is commonly called shale.
OriginMid 17th century (in the sense 'easily split'): from Latin fissilis, from fiss- 'split, cracked', from the verb findere.
