Title: Innovations of Jean H Raas

Introduction

Jean H Raas is a notable inventor based in Lynchburg, VA (US). He has made significant contributions to the field of nuclear engineering, holding a total of three patents. His work focuses on advancements in reactor technology, particularly in the design and functionality of fuel assemblies and control rod assemblies.

Latest Patents

One of his latest patents is for a small modular reactor fuel assembly. This invention involves a pressurized water reactor (PWR) that contains a pressure vessel filled with primary coolant water. The nuclear reactor core is situated within this vessel and consists of multiple fuel assemblies, each containing fuel rods with fissile material. The control system features several control rod assemblies (CRA's) that are guided by corresponding CRA guide structures. The design includes a support element above the CRA guide structures, which supports them effectively. The pressure vessel is typically cylindrical, and the support element is designed as a support plate with a circular periphery.

Another significant patent by Raas is the control rod assembly impact limiter. This assembly includes at least one movable control rod made from neutron-absorbing material. It features a control rod drive mechanism (CRDM) that regulates the movement of the control rod. The coupling mechanism connects the control rod to the CRDM and includes a kinetic energy absorbing element that mitigates kinetic energy during a SCRAM event. This innovative design enhances the safety and efficiency of nuclear reactors.
