METHOD OF LIFTING AND TRANSPORTING LARGE PARTS OF AN UNDERGROUND NUCLEAR POWER PLANT

摘要

FIELD: physics, nuclear physics.;SUBSTANCE: invention relates to nuclear power technology, namely to the method of lifting and transporting units in an underground nuclear power plant. Technical result is achieved due to fact that the claimed method of lifting and transporting large parts of an underground nuclear power plant comprises: stage 1: construction of beams with an anchorage in a rock formation of a power plant for a nuclear reactor, lifting a ring bridge construction machine through a vertical elevator shaft and installing it on the beams with an anchorage in the rock; stage 2: completion of excavation of the power plant for a nuclear reactor, installing a containment building cylinder and crane beams of the ring crane, lifting the ring crane into a vertical lift shaft by a bridge crane and installing a ring crane beam on the crane beams of the ring crane while the bridge crane and ring bridge construction machine operate together; stage 3: lifting the fragments of a steel inner lining of the dome of the containment in the entry of the power plant for a nuclear reactor from a vertical elevator shaft part by part using crane beams of the ring crane and beams of the ring crane as bearing points of carrying loads, as well as assembling and welding the fragments of the steel inner lining part by part; stage 4: transporting permanent large equipment to the containment building cylinder through the equipment transport passage, as well as turning and lifting equipment by using a ring crane beam.;EFFECT: technical result is convenience and rationality of the method, as well as the ease of lifting and transporting large-sized units in an underground nuclear power plant.;8 cl, 4 dwg
