A high-temperature gas-cooled reactor steam generating system comprises a plurality of nuclear steam supply systems, a high-pressure cylinder (), a low-pressure cylinder (), a condenser (), a condensate pump (), a low-pressure heater (), a deaerator (), a water supply pump (), and a high-pressure heater () which are sequentially connected end to end to form a close steam loop. On one hand, the inherent safety of the reactor is guaranteed and the generating system is simplified with the inherent safety. On the other hand, the scale economy of the steam engine system and other systems of a whole power station is guaranteed through batch copy, a shared auxiliary system and a scale effect.

High-temperature gas-cooled reactor steam generating system and method

A sealed transmission device for a helium space of a high temperature gas cooled reactor and a drive device thereof are disclosed. The helium space () is enclosed by a chamber body (), a pressure-bearing casing (), a fastener () and a sealing element (). A transmission member () is connected with an executing member () inside the helium space () and a motive member () outside the helium space () and transmits movements between them. The transmission member () is a magnetic shaft coupling which includes the pressure-bearing casing (), a driving magnetic component () arranged outside the pressure-bearing casing () and a driven magnetic component () arranged inside the pressure-bearing casing (). The motive member () and the driving magnetic component () are connected to each other to form a driving member, and the executing member () and the driven magnetic component () are connected to each other to form a driven member. The present invention can seal the thermal state radioactive helium space fully, and satisfy controllability and reliability requirements for the operations, such as big torque, long time and continuity, reciprocating rotation and frequent start and stop, etc.

Sealed transmission device for helium space of high temperature gas cooled reactor and drive device thereof

A steam generator includes a heat exchanger, a liquid header and a steam header. The heat exchanger is assembled by several heat exchanging subassemblies with the same structure. The heat exchanging subassembly includes a spiral heat transmission pipe bundle, a central cylinder and a sleeve. The spiral heat transmission pipes with different radii are concentrically and spirally arranged in an annular space between the central cylinder and the sleeve, to form one or more concentric heat exchanging pillar surfaces. One end of the liquid header is connected with a main water feeding pipe, and the other end of the liquid header is connected with the spiral heat transmission pipe bundle. One end of the steam header is connected with a main steam pipe, and the other end of the steam header is connected with the spiral heat transmission pipe bundle.
