According to the present invention, nuclear fuel pellets are stored in the pellet storage portion of the pellet holder main body 1, and the pellet holder main body is placed on a buffer member consisting of an elastic mechanism or the like in a container having heat resistance and impact resistance. Since the nuclear fuel pellets do not come into direct contact with the cushioning material, the rows of nuclear fuel pellets are compressed at both ends by elastic plugs within each pellet storage section, so the movement of each nuclear fuel pellet in the axial direction is ensured. In addition, the pellet storage section prevents the pellets from moving in the radial direction, so vibrations and
It is possible to prevent nuclear fuel pellets from being damaged due to impact or the like. Furthermore, by using an appropriate pushing device or the like, nuclear fuel pellets can be easily moved in and out of the pellet storage section, thereby reducing radiation exposure and improving work efficiency.
