English

Subject field(s)
  • Nuclear Fission Reactors
CONT

Advanced Fuel Fabrication and Refabrication. Current preparation of conventional pelletized reactor fuels for LWRs [light water reactor] and fast reactors requires grinding the pellets to achieve a specified size and shape. This process produces finely divided fuel particles that must be recovered and recycled. A “dust-free” sol-gel microsphere pelletization process has been developed for fabrication of (U,Pu)O2, (U,Pu)C, and (U,Pu)N fuel pellets containing around 15 percent plutonium.

CONT

Pelletizing (pressing), sintering … and rectification (grinding) to fabricate MOX [mixed oxide] pellets - pellets are usually 15 mm high with a diameter of 8.2 mm for EDF [Électricité de France] fuel, with a density of 10.4g/cm³ …

OBS

fuel pellet: Uranium dioxide, or other nuclear fuel in a powdered form, which has been pressed, sintered and ground to a cylindrical shape for insertion into the sheathing tubes of the fuel bundle.

French

Domaine(s)
  • Réacteurs nucléaires de fission
CONT

Pastillage. La mise en forme des pastilles est effectuée par compression des poudres, à froid, dans des presses multipoinçons à double effet : la pression exercée simultanément en haut et en bas garantit la symétrie des pastilles et une uniformité du champ de pression, donc de la densité, plus élevée que dans le cas d’une presse à simple effet.

OBS

pastille : Forme sous laquelle se présente le combustible de nombreux réacteurs nucléaires. (Les pastilles, souvent cylindriques, sont constituées, par exemple, d'oxyde d'uranium fritté.)

Record 2 2006-06-06

English

Subject field(s)
  • Mineral Processing (Metallurgy)
  • Iron
  • Processing of Mineral Products
DEF

In metallurgy, the process of forming a small round spherical body, frequently applied to metal ores, especially iron ore.

CONT

Iron ore consisting of mineral concentrates is usually processed further by pelletizing and sintering, and blended with other types of ore to improve the overall grade and structural quality of the furnace burden ...

French

Domaine(s)
  • Minéralurgie (Métallurgie)
  • Fer
  • Préparation des produits miniers
DEF

Procédé de fabrication d'agrégats sphériques de matériau, par passage et humidification de celui-ci dans un appareil rotatif (tambour ou disque bouleteur).

CONT

Le minerai de fer composé de concentrés de minéraux doit habituellement subir un traitement supplémentaire par boulettage et frittage et être mélangé avec d'autres types de minerai pour améliorer la teneur globale et la qualité structurale de la charge des fours [...]

OBS

L'orthographe «boulettage» qu'on rencontre parfois est impropre.

PHR

Usine de bouletage.

Spanish

Campo(s) temático(s)
  • Explotación de minerales (Metalurgia)
  • Hierro
  • Preparación de los productos mineros
DEF

Formación de pellets a partir de un material pulverulento.

Record 3 2003-07-10

English

Subject field(s)
  • Animal Feed (Agric.)
DEF

The process of making pelleted feeds.

OBS

Pelleted feed: a pill-like or cubical type of animal feed made by forcing the loose, bulky, or dusty feeds into small, uniform pellets by the use of grinding, molding, and compressing machinery.

Key term(s)
  • pelletization

French

Domaine(s)
  • Alimentation des animaux (Agric.)

Spanish

Campo(s) temático(s)
  • Alimentación animal (Agricultura)
DEF

Proceso mecánico que convierte el pienso preparado en forma de harina, en gránulos de tamaño adecuado a los animales que han de consumirlo.

Record 4 2001-08-20

English

Subject field(s)
  • Biochemistry
  • Wastewater Treatment
CONT

Monsoon in tropical countries can cause severe land erosion and, as a consequence, high turbidity in streams and rivers. Pelletization process is known to remove turbidity at very high efficiency and with smaller reactors as well as reduced capital and operation costs... The pellets, formed by sufficient agitation in the reaction zone, are very compact and dense, and thereby possess high settling velocity.

CONT

Water Treatment Plants and Operations. Improvement of the Turbidity Removal by Internal Pellet Recirculation in a Pelletisation Process.

French

Domaine(s)
  • Biochimie
  • Traitement des eaux usées
DEF

Mise en forme de pellets.

OBS

Les facteurs qui influencent la «pelletisation» sont : conditions de croissance et de floculation, brassage (horizontal/vertical et son intensité), hauteur du réacteur, démarrage, type d'eau (L'analyse écologique des boues activées, 1976, p. 18).
