Dividing method for radiation partitions of high-temperature gas cooled reactor

The invention relates to the technical field of nuclear reactor radiation partition, in particular to a high-temperature gas cooled reactor radiation partition division method, which comprises the following steps of: dividing a nuclear island plant into five plants including a reactor plant, a spent fuel plant, a nuclear auxiliary plant, an electrical plant and a nuclear auxiliary plant; each plant is divided into five radiation subareas including an ultrahigh radiation area, a high radiation area, a discontinuous working area, a conventional working area and a supervision area, and the radiation subareas are arranged on the-20.00 m layer, the-16.50 m layer, the-11.00 m layer, the-5.50 m layer, the +/-0.00 m layer, the 5.00 m layer, the 10.00 m layer, the 15.00 m layer, the 20.00 m layer and the 28.10-38.50 m layer in the nuclear island plant. According to the method provided by the invention, the problem that the high-radiation partition and the low-radiation partition of the high-temperature air-cooled nucl
