A liquid cooled nuclear reactor
Creators
Description
That reactor comprises a core immersed in a coolant mass contained in a vessel an a tray for receiving fuel scraps falling from said core; said tray comprises an assembly of collector open-topped containers provided with central support steams and a structure for supporting said containers the latter being spaced apart and distributed in layers, the container-pattern of each layer being off-set with respect to the patterns of the other layers so that the containers in any layer slightly overlap those in the lower layers, the arrangement being such that the whole constitutes an uninterrupted area for receiving falling circulating upwardly through convection. This can be applied to liquid cooled nuclear-reactors, and in particular to fast reactors
Abstract (French)
Ce reacteur comprend un coeur immerge dans une masse d'un caloporteur contenu dans une cuve et un plateau de reception des debris du combustible tombant dans le coeur, le plateau comprend un ensemble de recipients collecteurs ouverts au sommet ayant des montants centraux de support et une structue pour supporter les recipients qui sont espaces et disposes par couches en reseau, le reseau des recipients de chaque couche etant decale par rapport a ceux des autres couches de maniere que les recipients superieurs recouvrent en partie les recipients inferieurs, la disposition etant telle que l'ensemble forme une aire complete de reception des debris qui tombent tout en restant permeable au caloporteur liquide qui circule de bas en haut par convection. Ceci est applicable aux reacteurs nucleaires refroidis par un liquide notamment aux reacteurs rapidesAdditional details
