Abstract: The invention discloses a serial high-temperature gas-cooled reactor nuclear energy system and an operating method thereof. The serial high-temperature gas-cooled reactor nuclear energy system includes a plurality of high-temperature gas-cooled reactors and a serial gas-cooled reactor. The high-temperature gas-cooled reactor includes a first reactor pressure vessel comprising a first reaction chamber for accommodating the first fuel element; a second reactor pressure vessel comprising a second reaction chamber interconnected with the first reaction chamber, allowing the first spent fuel in the first reaction chamber to enter the second reaction chamber.

Abstract: A transverse adjustment mechanism for a bilateral half-spring type load-carrying head is installed in the casing of the load-carrying head of the lifting unit of a pit type unwheeling machine, fixedly connected with the casing, directly connected to an adjustment unit at the end of the load-carrying head, and installed on a lead screw of the adjustment unit. The transverse adjustment mechanism includes an adjusting nut, an adjusting nut guide, a guiding tube, and a guiding sleeve, a nut mounting plate, a flange plate, a compression spring and a sliding shaft. The invention is currently applied to the transverse adjustment of the no-loading heads and transverse fine adjustment of the load-carrying heads of a China Railway High-speed (CRH) train. The structure is reliable and practical, safe, convenient and energy-saving to use and satisfies the demand for the synchronous lifting operation of the entire CRH train of the compatible pit type unwheeling machine.
