IMPROVEMENTS RELATING TO SHOCK-ABSORBING DEVICES
Patent
·
OSTI ID:4135996
A shock-absorbing device is described which may be attached to the lower end of a reactor control rod or at the bottom of a control rod or fuel-element channel. The device comprises a telescopic tubular housing containing a plunger with screw threads. If the control rod has enough kinetic energy, the threads will strip, causing the housing to move downward relative to the plunger. If the control rod is dropped a second time and the housing-plunger movement has reached its limit, the telescopic sections of the housing will shear their grub screws and allow a further length of the thread to be stripped.
