The systems for mounting, controlling and guiding the control rods inside and outside the reactor vessel can be dispensed with and traversing the internal upper part can thus be avoided. According to the invention, an internal upper part (10) which is placed close to the core of the reactor (50) is used, said part leading laterally to the exterior of the vessel (1). All fluid transmission and control systems pass via said internal part and, due to a moveable connection part (11) for each cluster of control rods, and lead to an assembly head (12) containing reservoirs of neutron-absorbing liquid and injection circuits in injection channels placed between the fuel rods. The invention can be used in all nuclear reactors. |
