OSTI ID:4842252

A neutron-absorbing control rod able to move in the di rection of its axis and intended to be propelled into the reactor to produce the shut-down, is connected at the end remaining outside the reactor with a piston acting in a cylinder. Suitably the control rod enters in a vertical direction from beneath the reactor, and the piston rests without any fastening on a plate perpendicularly disposed with respect to the axis of the rod and is moved by mechanical means in the direction of the axis of the rod and thus controls the reactor. The side of the piston opposite the control rod is in communication with a first quantity of fluid under pressure, while the other side of the piston is in communication with a second quantity of fluid under pressure. For propelling the rod rapidly into the reactor, the pressure of the second quantity of fluid is released. (NPO)
