Title: The Innovative Contributions of Donald M. Barrus
Introduction
Donald M. Barrus is a notable inventor based in San Jose, California. He has made significant contributions to the field of nuclear reactor safety with a total of 5 patents to his name. His work focuses on developing systems that enhance the safety and efficiency of nuclear reactors.
Latest Patents
Among his latest patents is the "Thermionic Switched Self-Actuating Reactor Shutdown System." This innovative system incorporates a thermionic switched electromagnetic latch arrangement that responds to changes in reactor neutron flux and coolant temperature. The self-actuating nature of this system allows it to release the control rod without needing a signal from the main reactor plant protective and control systems. The system utilizes two detectors to monitor both temperature and neutron flux, ensuring a rapid response to any unsafe conditions.
Another significant patent is the "Self-Actuating Reactor Shutdown System." This control system is designed for the automatic shutdown or 'scram' of a nuclear reactor. It can initiate a scram insertion either through a signal from the plant protection system or by independently sensing reactor conditions such as low-flow or over-power. The system's design allows for a quick response to dangerous situations, enhancing reactor safety.
