Abstract

The invention relates to a telescopic spent fuel storage tank hoisting guide device which comprises a positioning annular plate (1), a top flange (2), an outer guide rib (5), an inner guide rib (7), a top reinforcing ring (3), a middle reinforcing ring (6) and a bottom reinforcing ring (9); the hoisting guide device also comprises a guide wheel assembly (8); the inner guide rib (7) is arranged inside the outer guide rib (5); and the guide wheel assembly (8) is arranged on the inner guide rib (7) and between the inner guide rib (7) and the outer guide rib (5). The telescopic spent fuel storage tank hoisting guide device can be used for hoisting guide and precise positioning of a spent fuel storage tank in a pebble-bed high temperature gas cooled reactor spent fuel storage system, so that the spent fuel storage tank can be hoisted into a shielding transferring container.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant reactor engineering, in particular to a retractable hoisting guide device for a spent fuel storage tank. Background technique [0002] While actively developing the pressurized water reactor nuclear power plant, our country is also actively developing the pebble bed modular high-temperature gas-cooled reactor nuclear power plant. It can generate high temperature process heat and other advantages. [0003] High-temperature gas-cooled reactors can be divided into two types according to the shape of fuel elements, one is the pebble bed high-temperature gas-cooled reactor using spherical fuel elements, and the other is columnar high-temperature gas-cooled reactors using prismatic fuel elements, spherical fuel elements and Coated fuel particles are dispersed in the prismatic fuel elements. The diameter of the coated fuel particles is about 1 mm. Spherical fuel element is to fully mix a c...
