Abstract

Improvements in nuclear reactors, in particular in their control rods, and method of operation; rods with primary and secondary ends to carry out the control in the distribution of the force of a nuclear reactor having a core with an active length "L" and that said rod has two ends of different characteristics for the absorption of the neutrons, characterized in that the rod has a primary part in said first end of the control rod comprising a first neutron absorbing material, by a secondary part in said second end of the control rod comprising a second neutron absorbing material, which is disposed of said primary part by a distance that is less than "L", as well as by a third party disposed between said primary and secondary parts; this third part comprises a material that is essentially non-neutron absorbing.
