| 1. | These are materials that sustain an explosive fast nuclear fission chain reaction.
|
| 2. | However, it is not known if any of this results from fission chain reactions.
|
| 3. | In nuclear engineering, "'fissile material "'is material capable of sustaining a nuclear fission chain reaction.
|
| 4. | The insertion of a single blade was sufficient to shut down the fission chain reaction.
|
| 5. | Producing a fission chain reaction in natural uranium fuel was found to be far from trivial.
|
| 6. | The nuclear fission chain reaction became self-sustaining and began to emit intense gamma and neutron radiation.
|
| 7. | Fission chain reactions occur because of interactions between neutrons and fissile isotopes ( such as 235 U ).
|
| 8. | Unlike the predominant isotope uranium-238, it is fissile, i . e ., it can sustain a fission chain reaction.
|
| 9. | However, if a sufficient quantity of uranium-235 could be isolated, it would allow for a fast neutron fission chain reaction.
|
| 10. | In addition to laser enrichment, the university carried out a test on neutron generator that can also trigger the fission chain reaction.
