Title: The Innovative Contributions of Fernand Savary

Introduction

Fernand Savary is a notable inventor based in Saint Leu La Foret, France. He has made significant contributions to the field of nuclear engineering, holding a total of seven patents. His work primarily focuses on enhancing the safety and efficiency of nuclear reactor systems.

Latest Patents

Among his latest patents is the "Neutron Absorbing Bar Damping Device." This invention features a neutron absorbing bar designed for use in a Pressurized Water Reactor (PWR). It includes an integrated damping device that consists of a cluster of vertical absorbent rods fixed to the arms of a spider. The central pommel of the device connects to a drive mechanism, while a damping device in the pommel incorporates a cylinder that receives a piston. This piston is urged into a downward position by springs contained within the cylinder. The design ensures that the leak flow at the cross-sectional area offered to the liquid gradually decreases as the piston moves from its outermost position. Additionally, the piston carries a hydromechanical damper that mitigates the initial impact of the bar during a scram.

Another significant patent is the "Nuclear Reactor Control Bar Drive Device." This device features a mobile valve and includes a cluster guide positioned above the reactor core. It comprises a casing that contains a drive mechanism connected to the reactor's interior through a sealing sheath. The control shaft is movable vertically within the sheath, linking the mechanism to the control bar. A thermal protection sleeve is interposed between the shaft and the sheath, allowing for fluid intake through a calibrated passage. A non-return valve is also included, which ensures that fluid flows only towards the drive mechanism.
