On appelle «neutrons rapides» les neutrons produits par les réactions de fission avant qu’ils ne soient ralentis par un grand nombre de chocs. Leur énergie va d’environ 0,1 MeV à 2 ou 3 MeV. Grâce à leur énergie, les neutrons rapides sont capables de fissionner, donc de détruire, non seulement les noyaux réputés fissiles mais les actinides, ces noyaux plus lourds que l’uranium qui s’accumulent dans le combustible des réacteurs. Si l’on désire brûler efficacement ces déchets radioactifs gênants, il faut des neutrons rapides. Les neutrons rapides permettent de faire fonctionner un réacteur en surgénération [...] Le handicap des neutrons rapides est leur faible probabilité d’interaction, appelée «section efficace». 3, record 2, French, - neutron%20rapide

Thermal neutrons are those that have been slowed down by a moderator to speeds characteristic of the local temperature. 4, record 5, English, - thermal%20neutron
Record number: 5, Textual support number: 2 CONT
The moderators consist of nuclei which are light and don't absorb neutrons. The neutrons hit the moderator, and bounce off, but in the process they lose a little energy. After enough such bounces, the neutrons are no faster than expected from their temperature. They are called "thermal neutrons" to reflect the fact that they have slowed down to thermal velocities. In summary: Fast neutrons bounce off the moderator and become thermal (slow) neutrons. 5, record 5, English, - thermal%20neutron
