REACTEUR NUCLEAIRE A EAU PRESSURISEE EXCLUSIVEMENT CHARGE DE COMBUSTIBLE OXYDE MIXTE ET ASSEMBLAGE DE COMBUSTIBLE NUCLEAIRE CORRESPONDANT.

摘要

The reactor (1) has a core for closing nuclear fuel assemblies (16) that comprise nuclear fuel pencils based on plutonium and uranium mixed oxide before irradiation. The fuel pencils have same isotopic composition of nuclear fuel and same plutonium nominal mass content, where the fuel pencils not contain a consumable neutron poison and contain inevitable impurities resulting from manufacture. Each assembly includes guide tubes for receiving pencils of a control cluster (20) and an instrumentation control tube (29).
