Development of fuel pellet manufacturing technology

High burnup of fuel is an important approach to reduce fuel cycle costs and the amount of spent fuel generated. Therefore, we are developing technologies to produce high-quality pellets by using atmosphere-controlled high-temperature heating furnaces, etc., to satisfy the required specifications of various pellet characteristics (density, crystal grain size, O/U, etc.).
