Title: Knut Emmert and His Nuclear Fuel Assembly Patent

Introduction

Knut Emmert is an inventor associated with Frankfurt, Germany, and Siemens Aktiengesellschaft. His patent work includes an invention designed to improve coolant flow in a boiling water reactor fuel assembly.

Latest Patents

Emmert is credited with 1 patent: “Nuclear Fuel Assembly Having a Transition Piece Providing a Reduced Flow.” The invention addresses flow resistance where coolant passes through a support plate and enters the lower end of a fuel assembly. It uses a conically tapered lower rim on the transition piece, fitted to a corresponding conical surface around the support-plate passage. The inlet is concentric with the passage and is sized to match or slightly exceed it, while lateral fingers extending into the passage help center the transition piece. The patent also describes streamlined fuel-rod end caps and ribs that space the lower tie plate from the fuel channel, creating peripheral through-holes to support coolant flow.

Career Highlights

Emmert’s documented patent contribution focuses on the design of boiling water reactor fuel assemblies. The described features aim to reduce coolant-flow resistance and improve the arrangement of components at the fuel assembly’s lower end.

Collaborations

Emmert’s listed coworkers include Dietrich Alter and Stefan Drecker. The available information identifies these professional associations but does not specify their roles in the patent.

Conclusion

Knut Emmert’s patent reflects an engineering approach to managing coolant flow through a boiling water reactor fuel assembly, with design features intended to reduce resistance and guide the flow at the assembly inlet.
