English

Subject field(s)
  • Nuclear Physics
DEF

The branch of nuclear reactor theory concerned with criticality calculations, such as the variation of degree of criticality with core compression by high explosives.

French

Domaine(s)
  • Physique nucléaire
DEF

Branche de la physique qui traite du cheminement des neutrons dans un système et des réactions nucléaires induites par ces neutrons, en particulier les réactions de fission à l'origine du dégagement d'énergie.

OBS

Par ses attaches avec la physique nucléaire, c'est une science du microscopique; mais le traitement statistique de la population des neutrons s'apparente à la théorie cinétique des gaz et se rattache donc aussi au macroscopique.

English

Subject field(s)
  • Nuclear Physics
CONT

Neutron physics is concerned primarily with interactions between neutrons and individual nuclei or with the use of neutron beams as analytical devices, whereas reactor physics considers neutrons primarily as fission-producing agents. In the hierarchy of professional classification, neutron physics and reactor physics are both ranked as subfields of the more generalized area of nuclear physics.
