Summary: | The invention discloses a high-uranium-density ATF nuclear fuel pellet and a preparation method thereof. The high-uranium-density ATF nuclear fuel pellet comprises a columnar inner area (10), an isolating layer (20) wrapping the outer surface of the inner area (10) and a peripheral area (30) wrapping the isolating layer (20). The inner zone (10) is made of nuclear fuel resistant to water and water vapor oxidation and high uranium density nuclear fuel; the peripheral area (30) is made of nuclear fuel resistant to water and water vapor oxidation; the mass of the high uranium density nuclear fuel accounts for 3%-50% of the total mass of the inner zone (10) and the isolation layer (20). According to the high-uranium-density ATF nuclear fuel pellet, the uranium loading amount of the pellet can be increased, the center temperature of the pellet is effectively reduced, and then the economical efficiency and safety of reactor operation are improved; the application of the high-uranium-density nuclear fuel in the wate |
