Abstract

886,317. Shock absorbers. A.E.I.-J. THOMPSON NUCLEAR ENERGY CO. Ltd. April 10, 1959 [March 26, 1958], No. 9738/58. Class 103 (1). [Also in Group XL (a)] Fracture or bending of a tubular control rod 2 caused by faulty lowering in the channel of a nuclear reactor is avoided by associating it through a series of deformable discs 15 with a buffer member 8. If the rod falls too fast, impact of the buffer at the bottom of the channel shears pins 12 and 11 and shock to the rod is absorbed in the discs 15.
