Record 1 2017-04-13

English

Subject field(s)
  • Nuclear Fission Reactors
CONT

The basic idea was expanded to include a manifold for each fuel assembly which would be constructed very similar to the spider-like control rod clusters presently used in reactors. All the rods in the cluster would be controlled by a single end-cap in the cluster head.

French

Domaine(s)
  • Réacteurs nucléaires de fission
CONT

Dans un REP [réacteur à eau sous pression], le cœur est généralement constitué d'assemblages carrés de 17x17 «crayons», qui sont des tubes cylindriques métalliques très allongés contenant la matière fissile ou le matériau absorbant. Un quart à un tiers de ces assemblages accueille également des grappes de commande (24 crayons absorbants répartis dans l'assemblage et réunis à leur partie supérieure par une «tête de grappe» [...]

Record 2 2011-12-22

English

Subject field(s)
  • Nuclear Fission Reactors
  • Nuclear Power Stations
CONT

The present invention relates to a modular nuclear fuel element, which can be adapted by an assembly system allowing it to be used in different nuclear power plants with horizontal and vertical cooling channels. The module is a cluster of parallel fuel rods mounted as circular concentric crowns and supported by a structural system. It has a single diameter fuel rod array where the ratio of the heat transfer area to the transverse rod area is higher than 330. It also has self-supporting fuel element spacer grids, which are collapsible sheaths attached to them with fewer than 13 welded end stoppers.

Record 3 2009-04-22

English

Subject field(s)
  • Nuclear Fission Reactors
  • Nuclear Power Stations
DEF

The elementary unit of the core of a reactor, containing the nuclear fuel.

CONT

Each fuel element includes a cladding, or metal case, that covers the fuel. The cladding prevents the escape of fission products, and it does not readily absorb neutrons.

CONT

[A] fuel element [...] may consist of a single cartridge, or a cluster of fuel pins.

OBS

fuel element: term standardized by ISO.

French

Domaine(s)
  • Réacteurs nucléaires de fission
  • Centrales nucléaires
DEF

[...] plus petit élément ayant une structure propre dans un réacteur, et contenant du combustible nucléaire comme principal constituant.

CONT

Dans un réacteur à eau pressurisée, les éléments combustibles consistent en un assemblage solidaire de plus de 200 tubes, appelés crayons, remplis de pastilles d'uranium [...]

OBS

élément combustible : terme et définition normalisés par l'ISO.

Spanish

Campo(s) temático(s)
  • Reactores nucleares de fisión
  • Centrales nucleares
DEF

Red cuadrada donde se colocan las barras de combustible de uranio en los reactores nucleares.

Subject field(s)
  • Agricultural Economics
CONT

Cluster of industries involved in value-added economic activity related to agriculture. Core strengths include crop farming of cereals, oilseeds, pulse, specialty crops and the raising of livestocks. Value added diversification includes grain milling, oilseed crushing, food and crop processing, agriculture biotechnology, agricultural equipment manufacturing, farm services, agricultural chemicals and plant derived fuel, among others.
