BOUFFEE NEUTRONS [3 records]

Record 1 2016-09-20

English

Subject field(s)
  • Atomic Physics
DEF

As applied to nuclear kinteics, a short and intense emission of neutrons which is due, most of the time, to a fast divergence in a neutron multiplying media.

OBS

neutron burst: term extracted from the “Glossaire de l’énergie nucléaire” and reproduced with permission of the Organisation for Economic Co-operation and Development.

French

Domaine(s)
  • Physique atomique
DEF

En cinétique des réacteurs, émission intense et brève de neutrons due, le plus souvent, à une divergence rapide d’un milieu multiplicateur de neutrons.

Record 2 2014-11-03

English

Subject field(s)
  • Atomic Physics
  • CBRNE Weapons
DEF

The action which sets off a chain reaction in a fissile mass which has reached the critical state (generally by the emission of a "spurt" of neutrons).

OBS

initiation: term and definition standardized by NATO in the AAP-6 standard published in 1998, but not included in the 2014 version.

French

Domaine(s)
  • Physique atomique
  • Armes CBRNE
DEF

Action provoquant la réaction en chaîne dans une masse fissile ayant atteint l'état critique(en général par émission d’une «bouffée» de neutrons).

OBS

amorçage : terme et définition normalisés par l’OTAN dans la norme AAP-6 de 1998, mais non repris dans l’édition de 2014.

Spanish

Campo(s) temático(s)
  • Física atómica
  • Armas QBRNE
DEF

La acción que origina una reacción en cadena en una masa fisionable, que ha alcanzado el estado crítico (generalmente por la emisión de neutrones acelerados).

Record 3 2010-11-26

English

Subject field(s)
  • Analytical Chemistry
  • Atomic Physics
DEF

A device used for the detection of spontaneous neutrons when the neutron source is not working, as well as the detection of fission neutrons emitted following a neutron burst originating from the source.

OBS

Detector blocks are used mainly for the detection of fission materials.

French

Domaine(s)
  • Chimie analytique
  • Physique atomique
DEF

[En détection des matières fissiles, ] dispositif [qui] permet la détection des neutrons spontanés lorsque la source de neutrons ne fonctionne pas ainsi que la détection des neutrons de fission émis après une bouffée de neutrons provenant de la source.

CONT

Bloc de détection pour le comptage des neutrons prompts de fission lors d’une interrogation neutronique au moyen d’un générateur de neutrons.
