Title: Innovations by Jens G Andersen in Nuclear Reactor Technology

Introduction

Jens G Andersen is a notable inventor based in Wilmington, NC (US). He has made significant contributions to the field of nuclear reactor technology, holding 2 patents that focus on enhancing the safety and efficiency of boiling water reactors.

Latest Patents

One of his latest patents is a "Method and system for direct evaluation of operating limit minimum." This invention presents a method and system for thermal-dynamic modeling and performance evaluation of a nuclear Boiling Water Reactor (BWR) core design. The data processing system executes specific program routines that simulate the thermal operating characteristics of fuel rods during transient operational conditions. It compiles a transient response histogram that incorporates the effect of inherent uncertainties in various parameters of interest. The method employs a multi-dimensional approach for simulating operational events that produce transient conditions in the reactor, such as single operator errors or equipment malfunctions. The operating limit minimum critical power ratio (OLMCPR) of the reactor is directly evaluated from a histogram of probability calculations representing the number of fuel rods subject to a boiling transition during the transient condition.

Another significant patent is related to "Cooled water rod (LOCA conditions)." This invention utilizes a large water rod of a fuel bundle in a boiling water reactor fuel assembly as a radiation heat sink during a loss of coolant accident. Core cooling spray is collected at the top end of the bundle's large water rod and distributed to coat the inside wall surfaces of the water rod. The design modifications ensure the separation of downward flow of liquid water from the upward flow of steam, enhancing the reactor's safety during normal operations.
