Control rod arrangement particularly for boiling water reactors
Abstract
Abstract An improved control rod arrangement for a nuclear reactor, and in particular a boiling water reactor, of the type wherein the absorber portion of the control rod has a cross-shaped cross section, a coaxial guide tube is provided for guiding the control rod outside of the reactor and the control rod is provided with a lifting piston which cooperates with a lifting cylinder to insert the control rod into the reactor core from the bottom. According to the invention, the control rod guide tube is designed to simultaneously serve as the lifting cylinder and the absorber portion of the control rod is designed so that the four wings of the cross-shaped cross section will pass over the control rod guide tube, e.g. by providing each of the wings with an upwardly extending slit.
