Fission Product Containment. Uranium dioxide holds 95% of the fission products within its structure. Most of the fission products released come from the hot inner part of the pellet. These migrate to cracks in the cooler part of the pellet and escape into the spaces between the pellets. Some of this free inventory escapes if the fuel element ruptures.

CONT

Confinement des produits de fission. Le dioxyde d'uranium conserve dans sa structure 95 % des produits de fission. La plupart des produits de fission libérés proviennent de la région chaude au coeur de la pastille. Ils se diffusent par les fissures dans la partie plus froide des pastilles et s'échappent dans les cavités entre les pastilles. Une partie des substances libres s'échappera si le crayon de combustible se brise.
