This invention discloses a nuclear power generation and hydrogen production integrated utilization system, relating to the field of nuclear power hydrogen production technology. The key technical point is that by simultaneously distributing the high-temperature thermal energy of a molten salt reactor to a supercritical carbon dioxide Brayton cycle power generation system and a three-step vanadium-chlorine thermochemical cycle hydrogen production system, a new parallel-coupled, cascaded energy conversion architecture is constructed. This fundamentally overcomes the drawback of mismatch between heat grade and energy demand in traditional series-type nuclear power integrated utilization schemes. This design not only enables efficient power generation from high-temperature thermal energy and gentle hydrogen production from mid-temperature thermal energy, but also achieves deep recovery of waste heat through an internal heat exchange network, significantly improving the overall energy utilization efficiency of the system. The invention demonstrates significant technological progress in improving energy utilization efficiency, reducing production costs, and decreasing carbon emissions, providing a practical technical path for the multi-product integrated utilization of nuclear energy and large-scale green hydrogen production.

This invention provides a high-power, high-isolation coaxial power divider / combiner, relating to the field of microwave communication device technology. It solves the limitations of traditional power dividers / combiners, such as poor standing wave ratio (SWR) at the power divider ports and lack of isolation between adjacent ports. The power divider / combiner includes a common port, multiple branch ports, and multiple branch line structures. The common port is located on one of the branch line structures, which symmetrically connects to the other branch line structures, which in turn connect to the multiple branch ports. Each branch line structure also has multiple isolation ports for connecting isolation resistors. When used as a power divider, the common port receives the signal input, and each branch port outputs a signal with evenly distributed energy. When used as a combiner, the principle is reversed. This invention, through structural design and the use of isolation resistors, ensures the SWR at the output ports and guarantees the isolation between adjacent ports.
