Record 3 2014-07-17

English

Subject field(s)
  • Nuclear Fission Reactors
CONT

Experimental techniques for subcriticality measurement are … being investigated. … This is being accomplished through the use of either a single-or multiple-unit core system containing fuel solution … a series of experiments is also being performed on a heterogeneous core containing an array of low enriched oxide fuel rods immersed in the fuel solution.

Record 4 2010-04-01

English

Subject field(s)
  • Nuclear Fission Reactors
CONT

Experimental techniques for subcriticality measurement are … being investigated. … There are radial heterogeneous cores and axial ones. In the former, blanket fuel assemblies are arranged among the seed fuel assemblies, and are called the radial blanket. In the latter, the blanket fuel regions are inserted within the seed fuel regions in the seed fuel assemblies, and are called the internal blanket.

French

Domaine(s)
  • Réacteurs nucléaires de fission
CONT

[…] différentes méthodes visant à réduire les conséquences de la vidange totale du caloporteur dans le concept de cœur EFR [European Fast Reactor] à combustible nitrure U-Pu-N sont évaluées; il s'agit de l'élaboration d'un cœur hétérogène radial, de la réduction de la hauteur de la colonne fissile et de l'introduction de modérateur dans le cœur.

Record 6 1999-05-03

English

Subject field(s)
  • Geophysics
CONT

The heat-known model of heterogeneous-accretion... visualizes the core material as condensing early and accreting before condensation is complete, indeed before the mantle silicates can condense and begin to accrete.

CONT

Heterogeneous Accretion.-As the nebula cooled, the refractory materials accreted into a single core, and later, less refractory materials added on, in layers, to give an iron rich core overlain by silicates.

French

Domaine(s)
  • Géophysique
CONT

Dans le modèle le plus connu d'accrétion hétérogène [...] le matériau du noyau se condense très tôt et s'accrète avant que la condensation ne soit terminée, c'est-à-dire avant que les silicates du manteau ne se condensent et commencent à s'accréter.

CONT

[...] modèle basé sur une accrétion hétérogène [...]
