摘要： A device for treating uranium tailings with microorganism is provided and includes a treatment container, a spray water distribution assembly, a microbial incubator and a first pump. The water is transported from the microbial incubator to the spray water distribution assembly through the first pump, allowing the microorganisms to enter the interior of the uranium tailings in the treatment container. After treatment is completed, the water is collected by the water collection cylinder and sent back to the microbial incubator for recovery, so as to reduce the waste of microorganisms. The even distribution of horizontal spray pipes can evenly spray water containing microorganisms on the uranium tailings in the treatment container, which makes the distribution of microorganisms in the uranium tailings more uniform and can prevent inadequate treatment and improve the treatment efficiency of microorganisms on uranium tailings.

摘要： An automatic leveling type maintenance platform for a high-temperature gas cooled reactor is provided. A floating plate is automatically leveled by using a leveling liquid, and during leveling, only a water driving assembly needs to be controlled to drive a housing to be close to an inner bottom surface of a liquid storage groove, and a sliding block assembly and a lifting guide mechanism are controlled to be locked and fixed after the floating plate is leveled. In this way, complex and time-consuming fine adjustment control does not need to be performed, and the floating plate can implement automatic and rapid leveling and locking operation, so that a leveling effect is better. When the maintenance platform is used in a spherical top cap of a pressure vessel of the high-temperature gas cooled reactor for maintenance operation, support legs of a support assembly do not need to perform telescopic motion.

摘要： The present invention relates to a method for load-dependent unloading and/or loading of a fuel element out of and into a fuel element container, especially a reactor pressure vessel, by means of a loading device. The loading device is designed to lift a fuel element out of the fuel element container or to lower it into the fuel element container along a path of travel at a variable speed of travel. The loading device has a load-measuring device for online measurement of a dynamic load and/or load change acting at the time on the loading device along the path of travel during lifting or lowering of the fuel element, the speed of travel during lifting or lowering of the fuel element being subject to closed-loop control in dependence upon the load and/or load change being measured at the time.

摘要： An x-ray breast imaging system includes a breast support platform including an x-ray receptor, and an x-ray tube head. The x-ray tube head includes an x-ray source configured to emit an x-ray beam in a direction towards the x-ray receptor, and a collimator. A filter assembly including a plurality of filter slots selectively positionable adjacent to the collimator, and a specimen imaging filter disposed within a slot of the plurality of filter slots. The specimen imaging filter includes at least one aperture defined therein. The specimen imaging filter also blocks a portion of the emitted x-ray beam so that the at least one aperture defines a path of the emitted x-ray beam towards the x-ray receptor.

摘要： A method of generating a radionuclide includes receiving a container in a container receptacle of a radionuclide generator, and moving the container in the container receptacle from a first pose to a second pose. The method also includes exposing an interior surface of the container to a precursor radionuclide source while the container is in the second pose, and allowing sufficient time for the precursor radionuclide source to decay into one or more progeny radionuclides and to emanate the one or more progeny radionuclides into the container. The method further includes isolating the precursor radionuclide source from the container while the container is in the first pose.

摘要： Systems and methods for insulating vessels are disclosed. In one or more embodiments, the disclosure provides a vessel insulation system (e.g., for use with a reactor or pressure vessel), which includes a floating ring sized to circumscribe a top nozzle of a vessel; a plurality of straps connected to the floating ring, the plurality of straps extending downward from the floating ring and being positioned to run along a length of the outer shell of the vessel; and a plurality of segmented rings positioned to circumscribe the outer shell of the vessel and connected to the plurality of straps. The plurality of segmented rings is configured to support an insulation material circumscribing the outer shell of the vessel, which can provide effective securement of the insulation material around the outer shell without welding components on the vessel to secure the insulation material.
