Record 1 2017-04-19

English

Subject field(s)
  • Metrology and Units of Measure
  • Nuclear Physics
DEF

A unit of reactivity equal to that amount of reactivity required to make a reactor critical on prompt neutrons only, and therefore equal to the effective delayed neutron fraction for that reactor.

French

Domaine(s)
  • Unités de mesure et métrologie
  • Physique nucléaire
DEF

Unité de réactivité, égale à la quantité de réactivité nécessaire pour rendre un réacteur critique à l'aide des neutrons instantanés seulement, et donc égale à la fraction efficace de neutrons retardés pour ce réacteur.

OBS

La valeur du dollar varie sensiblement de 300 pcm (parties pour cent mille) pour un cœur au plutonium239 à650 pcm pour un cœur à l’uranium235.

Record 2 2015-05-05

English

Subject field(s)
  • Atomic Physics
DEF

Fulfilling the condition that a nuclear chain reacting medium is critical utilizing prompt neutrons only.

OBS

prompt critical : term and defintion standardized by ISO.

French

Domaine(s)
  • Physique atomique
DEF

[Qui remplit] les conditions requises pour qu'un milieu siège d'une réaction nucléaire en chaîne soit critique sous l'action des seuls neutrons instantanés.

Record 3 - external organization data 2009-03-01

English

Subject field(s)
  • Nuclear Physics
  • Nuclear Fission Reactors
  • Compartment - Canadian Nuclear Safety Commission
CONT

In nuclear engineering, an assembly is prompt critical if for each nuclear fission event, one or more of the immediate or prompt neutrons released causes an additional fission event. This causes a rapidly exponential increase in the number of fission events, and an explosion.

French

Domaine(s)
  • Physique nucléaire
  • Réacteurs nucléaires de fission
  • Tiroir - Commission canadienne de sûreté nucléaire
DEF

Criticité qui serait atteinte sous l'action des seuls neutrons instantanés et conduirait à une situation accidentelle grave.

CONT

Effet des neutrons instantanés considérés seuls, et criticité instantanée. Les équations de la période du réacteur et des changements de puissance (1, 2, 3 et 4) permettent de prévoir avec exactitude les changements de puissance en autant que [delta majuscule]k prenne une valeur faible, ce qui est propre aux additions de réactivité effectuées pour la régulation normale du réacteur.

Record 4 1995-06-22

English

Subject field(s)
  • Political Institutions
DEF

Undue increase of direct and participatory democracy criticized by technophobic elites.

CONT

Voters are more discerning than the critics of hyperdemocracy. Technology's new challenge ideally at least, is to re-empower voters and revitalize democracy through more direct popular representation. Pitfalls do abound. The same technology able to identify and link citizens and political institutions will also necessarily facilitate nationwide identification systems and increased governmental surveillance. This will undoubtedly prompt a second neo-Orwellian howl to accompany an elitist shudder over entrusting the people-the booboisie as a 21st century cybermob. But overall, the favorable balance that should result is compelling. Here are five critical circumstances and developments that we should all monitor carefully in the future : putting politics on line, creating virtual Washington, expanding individual voting, creating national referendums, and increasing choice of parties.
