とを特徴とする原子炉用の制御棒。 a cladding tube, a neutron absorber housed in the cladding tube, an upper end plug and a lower end plug that close the upper and lower ends of the cladding tube, respectively, and arranged between the upper end plug and the neutron absorber. In a control rod for a nuclear reactor equipped with a coil spring, a cylindrical sleeve whose outer diameter is approximately the same as the outer diameter of the neutron absorber is disposed at the upper end between the coil spring and the cladding tube. The sleeve is arranged from the plug to the upper end of the neutron absorber, and the inner surface of the lower end of the sleeve is a diverging conical surface so as to slidably receive the upper end of the neutron absorber. Control rod for furnace.
