high temperature gas cooled reactor of pebble bed
The pebble-bed high-temperature gas-cooled reactor refers to a high-temperature gas-cooled reactor in which hundreds of thousands of fuel balls with a diameter of 60 mm are packed into a large container to reach a critical point. The fuel balls are continuously loaded into the core from the top of the reactor and discharged continuously from the discharge pipe at the bottom of the core. Measure the burnup of the discharged fuel ball, and if it does not reach the predetermined burnup depth, send it back to the stack again for use.
