Abstract: A current measuring system for measuring current from a conductor comprises a first and second circuit and a current measurer connected to a conductor connected to a first power source. The first circuit comprises an inverting operational amplifier, which generates a first threshold signal when current flows into the first power source. The second circuit comprises a biasing circuit and a non-inverting operational amplifier, which generates the first threshold signal at the second output when current flows out of the first power source.

Abstract: An electronic personal dosimeter (EPD) smart accessory system is described. The system includes a first component configured to be attachable to the EPD and a second component configured to be attachable to safety glasses. The first component includes an ambient light sensor and a first communication module. The ambient light sensor detects light from a light-emitting diode (LED) of the EPD to detect a warning signal from the EPD. The second component includes a feedback mechanism and a second communication module. The first communication module establishes a short range wireless communication connection with the second communication module, and transmits a signal to cause the second component to turn on the feedback mechanism when the warning signal from the EPD is detected.

Abstract: A device and method for performing ultra-sound scanning of a substantially cylindrical object. The device comprises a cuff adapted to fit around a circumference of the object, an ultrasound probe mounted about the inner circumference of the cuff and positioned to scan the circumference of the object, and one or more data connections providing control information for the ultrasound probe and receiving scanning data from the ultrasound probe. The probe includes one or more sensors to determine its orientation or location, and this data is used to control the operation of the device and to process data from the array.

Abstract: Disclosed is a racking tool for use with a breaker having a frontwardly-projecting racking screw, the screw being rotatable, about a frontwardly-orientated screw axis, between connected and disconnected positions. The racking tool comprises: a gripping tool that, in use, engages said screw and is rotatable about the screw axis to drive the screw between the connected and disconnected positions; an angle drive mechanism coupled to the gripping tool: and a shaft having a first end operatively coupled to the drive mechanism, a second end and a shaft axis extending from the first to the second end, the shaft, in use, being angularly orientated to the screw axis and adapted such that, with the gripping tool engaged with said racking screw, the screw can be rotated between the connected and disconnected positions by a user standing to one side of the breaker and rotating the shaft about its axis.

Abstract: An apparatus and method for determining terminal solid solubility temperature in materials capable of forming hydrides, such as reactor pressure tubes. An inspection device is positioned within the reactor pressure tube under test and a pair of annular seals are radially deployed to seal a section of the pressure tube. Any water within the sealed section is displaced through the injection of gas and the heating of the sealed section to dry the tube and the device. A probe assembly on the device is deployed to contact the interior surface of the pressure tube and measure 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, is reheated at a predetermined rate, and is allowed to cool again.

Abstract: A filter having filter elements with outwardly flanged ends sealed together. The seal may be secured by use of a rod extending in a lengthwise direction through apertures in the flanged ends. The rod has one end releasably securing the filter element and a second end secured to the housing. A frame can cover the filter elements, and a jack screw in the frame can be used to apply force to the filter elements to secure the seals. The filter may have a cleaning apparatus capable of suctioning material from the filter element.

Abstract: A non-venting current limiting fuse for mounting in a cutout comprises a high current fuse component and a low current fuse component housed in separate compartments of a housing and connected in series. Interruption of a low current overload results in operation of the low current fuse component only, with the high current component being unaffected. The low current fuse component is removable from the housing such that when a low current overload situation exists, the low current fuse component can be simply removed and replaced without the need for replacement of the more costly high current fuse component.

Abstract: A method and apparatus for in-line tritium-in-water monitoring in which a sample of water is vaporized at a temperature sufficient to transform it to dry water vapor substantially free of liquid water droplets. The water vapor is transferred to a tritium detection device having a chamber heated to a temperature at which there is substantially no condensation of the water vapor, the detection device comprising volume detection device adapted to detect .beta.-decay of tritium atoms in the water vapor. The volume detection device may comprise ionization chamber detector, gas scintillation counting detector and gas electron multiplier detector. The method and apparatus are preferably used to detect leaks of tritiated water from the primary to secondary side of the heat transport systems associated with certain types of nuclear reactors, and when used on an in-line, continuous basis, provide a time response as low as 10 seconds with the detection limits depending on the type of volume detection equipment used.
