Title: Erhard Friedrich: Innovator in Nuclear Technology

Introduction

Erhard Friedrich is a notable inventor based in Eckental, Germany. He has made significant contributions to the field of nuclear technology, holding a total of 11 patents. His work focuses on enhancing the safety and efficiency of nuclear fuel assemblies.

Latest Patents

One of his latest patents is a nuclear fuel assembly for a boiling water reactor with a redundant load chain. This innovative assembly extends along a fuel assembly axis and includes a base with a lower tie plate, a head with an upper tie plate and a lift handle, and a bundle of fuel rods. A water channel within the bundle connects the base to the head, ensuring that the load is effectively transferred. Additionally, the assembly features a tie rod that is axially fixed to the base and connected to the head through a connection assembly. This design limits the downward movement of the base relative to the head during lifting, particularly in the event of a breakage of the water channel.

Another significant patent involves a connecting device for linking a guide tube to a lower end nozzle in a nuclear fuel assembly. This device comprises a nut, a screw, and a body with a bore for securing the screw to the nut. A screw locking device is included to prevent loosening, ensuring the screw remains axially retained in the body even after unscrewing.
