The application relates to the technical field of
nuclear reactor engineering safety, and discloses a
helium temperature field technical balancing device and method for a high-temperature gas cooled reactor, which comprises a reactor hot gas guide
pipe, a
mixed flow guide component fixed in the guide
pipe, a
temperature monitoring array, an active
spoiler system integrated on the component and a
control unit. The
mixed flow guide component has a porous
honeycomb structure, and the active
spoiler system comprises rotatable spoilers and a wall-penetrating driving mechanism. According to the application, the
airflow is physically divided by the static
honeycomb structure, the spoilers are deflected by driving the spoilers according to the real-time monitored
temperature difference data by the
control unit, directional disturbance is applied to the local high-temperature area,
thermal expansion compensation and pressure boundary sealing design are adopted, the high-temperature and high-pressure working conditions are adapted, and the fault reset function is provided, so that the
helium thermal stratification problem is effectively solved, and the
safe operation of the reactor hot gas guide
pipe and downstream equipment is guaranteed.
