Latest Patents

Mario Ng holds a patent for "Methods and apparatus for inspecting reactor pressure tubes." This invention provides an apparatus and method for determining terminal solid solubility temperature in materials capable of forming hydrides, such as reactor pressure tubes. The inspection device is strategically positioned within the reactor pressure tube under test, where a pair of annular seals are radially deployed to seal a section of the pressure tube. The method involves displacing any water within the sealed section through the injection of gas and heating the sealed section to dry both the tube and the device. A probe assembly on the device contacts the interior surface of the pressure tube and measures resistivity changes in the pressure tube wall as a function of temperature. The probe assembly includes a thermocouple probe for measuring temperature and transmit and receive coils for inducing eddy currents within the pressure tube wall. The pressure tube is allowed to cool at a predetermined rate, reheated at a predetermined rate, and then allowed to cool again. Discontinuities within the temperature coefficient of resistivity indicate terminal solid solubility temperatures of precipitation or dissolution, which can be used to determine the hydrogen concentration of the sealed section of the reactor pressure tube. Mario Ng has 1 patent to his name.
