In contrast to the prismatic fuel, the coated particles are homogeneously distributed within the spherical fuel matrix, which acts as the moderator. There are two generic concepts for pebble bed reactors in terms of refueling.... Another type is the once through then out(OTTO) concept where the pebbles only perform one passage through the core. For the on-line refueling designs, the pebbles are circulated by gravity in the core, which is surrounded by a graphite reflector and pneumatically transported in the fuel handling system. 1, record 1, English, - once%20through%20then%20out%20concept

Cœur à boulets [...] Les promoteurs de ce genre de réacteur [THTR 300] ont imaginé une simplification du système de manutention, qui consiste à faire passer chaque boulet une seule fois dans le cœur (variante OTTO ou once through then out). Il suffit alors de recueillir, dans une sorte de pondoir, les boulets usagés, mais si l'on gagne en simplicité du système, la combustion massique du combustible déchargé n'est plus uniforme et l'utilisation du combustible n'est donc pas optimale. 2, record 1, French, - concept%20du%20passage%20unique

Radiation damage in solids … Because the particles … have different energies and different ranges, the distance from the site of formation to the region where they cause damage is different. Thus, the size of the fissile kernels itself(also called inclusions) embedded in the inert matrix material becomes an important factor in determining the regions of damage in a material. To this end a distinction is made between a microdispersed and a macrodispersed fuel. A fuel is called microdispersed if the size of the fissile inclusions is less than 10 [micrometers], and otherwise is called macrodispersed. Microdispersed fuels can be produced either by infiltration or by compression of a mixture of matrix grains and fissile grains, while macrodispersed fuels can be produced by compression only. The damage effects in microdispersed fuels will approach those in a solid solution, while the radiation effects in macrodispersed fuels will mainly occur in the inclusions themselves and in a thin matrix layer around the inclusion, predominantly due to neutron damage. 1, record 4, English, - microdispersed%20fuel

A este mineral se le someta a diferentes procesos para lograr que llegue a contener aproximadamente el 3% de núcleos de uranio 235, que son los que darán lugar a la reacción en cadena. El combustible nuclear se prepara en forma de pastillas. Estas pastillas de combustible se colocan en unos tubos inoxidables y después en el núcleo del reactor. 6, record 11, Spanish, - pastilla
