Title: Gary D Althenhein: Innovator in Nuclear Safety Systems
Introduction
Gary D Althenhein is a notable inventor based in Enfield, CT (US), recognized for his contributions to safety systems in nuclear power plants. With a total of 2 patents, Althenhein has made significant advancements in the field of engineered safety features.
Latest Patents
His latest patents include a Digital Engineered Safety Features Actuation System, which serves as an interface between a Plant Protection System and Engineered Safety Features in a nuclear power plant. This system continuously monitors the plant protection system initiation circuit for each remotely actuated Engineered Safety Feature system, allowing for remedial action in the event of a 'trip' signal. The system utilizes actuation inputs from the Plant Protection System along with manual operator inputs to control remote equipment components such as solenoid valves, motor-operated valves, pumps, fans, and dampers. Another significant patent is the Digital Plant Protection System, designed for pressurized water type nuclear power plants. This system features cross-connected sensed-parameter processing channels that provide a conditioned digital value to a comparator, which tests the value against a predetermined threshold to determine if the sensed parameter has been exceeded. If a parameter is deemed out-of-specification by two of four or more channels, a 'trip' signal is generated to initiate remedial action.
