Abstract

The invention belongs to the technical field of reactor engineering, and particularly discloses a coordinate ground vehicle system of a nuclear power plant, which includes a shielding case, a first movable device and a second movable device, wherein the shielding case is fixed in a hole formed in the first movable device, and a storage basin hoist is arranged in an inner cavity of the shielding case; the first movable device includes a first wheel, the second movable device includes a plurality of beams that are arranged in front-rear way and a second wheel mounted at two ends of the beams, a first track is mounted on the multiple beams, and the first movable device can move left and right along the first track through the first wheel; and a shaft is arranged below the second movable device, a shielding floor is arranged at the top of the shaft, a shaft opening is formed in the shielding floor, a shielding shaft cover is mounted in the shaft opening, and a shaft cover gripping apparatus is arranged above the shielding shaft cover. The coordinate ground vehicle system can realize the precise operation and safe operation of high-temperature reactor spent fuel storage shaft.

Description

technical field [0001] The invention belongs to the technical field of reactor engineering, in particular to a nuclear power plant coordinate ground vehicle system. Background technique [0002] The high-temperature reactor nuclear power plant is recognized as a nuclear power plant with the main characteristics of the fourth-generation nuclear power, which has the advantages of inherent safety, nuclear proliferation prevention, and high-temperature process heat generation. [0003] The pebble bed high-temperature gas-cooled reactor adopts spherical fuel elements, and coated fuel particles are dispersed in the fuel elements. Spherical fuel element is to fully mix a certain amount of fuel particles and matrix graphite, press it into a graphite ball with a diameter of 50mm, and then wrap and press a layer of pure graphite on the outside as the shell of the fuel element. The outer diameter of the pressed fuel element is 60mm. The spherical spent fuel discharged from the core of...
