Title: Shakir U Zaman: Innovator in Nuclear Reactor Safety Mechanisms
Introduction
Shakir U Zaman is a notable inventor based in Windsor, CT (US). He has made significant contributions to the field of nuclear reactor safety, holding a total of 3 patents. His work focuses on developing mechanisms that enhance the safety and efficiency of liquid metal nuclear reactors.
Latest Patents
One of his latest patents is the "Temperature Sensitive Self-Actuated Scram Mechanism." This invention features a self-actuated mechanism within a safety assembly in a liquid metal nuclear reactor. It comprises sensor fuel pins located in a reactor coolant flow path, a sensor bulb containing NaK located near the upper end of the sensor fuel pins, and a sensor tube connecting the sensor bulb to a metal bellows and push rod. The motion of the push rod, resulting from the temperature-dependent change in the NaK volume, actuates a safety rod release mechanism when a predetermined coolant temperature is reached.
Another significant patent is the "Hydraulic Latch Scram Release Mechanism." This invention involves a poison bundle release mechanism within a safety assembly of a liquid metal nuclear reactor. A baffle consisting of a plate with recesses in fluid communication with low-pressure coolant is formed in the upper portion of the safety assembly. A plug attached to the upper end of the poison bundle fits snugly against the recesses and is held up against the plate by the coolant pressure difference acting on the lower and upper sides of the plug. A conduit and valve arrangement within the plug allows high-pressure coolant to enter the recessed region, reducing the pressure difference across the plug and producing rapid disengagement from the plate.
