METHOD FOR CONSTRUCTING LINER PLATE OF SPENT NUCLEAR FUEL STORAGE POOL BY PRODUCING LINER PLATE ASSEMBLIES FROM PLANES OF NUCLEAR FUEL STORAGE POOL IN ADVANCE AND WELDING EDGES THE ASSEMBLIES DURING CONSTRUCTION

摘要

PURPOSE: A method is provided to allow for ease of construction and reduce costs by producing liner plate assemblies from planes of a nuclear fuel storage pool in advance and welding edges of the assemblies during construction. CONSTITUTION: A method comprises a step of dividing a polygonal nuclear fuel storage pool into planes(110,120,130,140,150,160) and producing vertical liner plate segments(211 to 262) by dividing each of the planes in a vertical direction; a step of arranging a bottom board for in-advance welding of the liner plate segments; a step of producing liner plate assemblies(210,220,230,240,260) by welding the vertical liner plate segments for each of the planes on the bottom board; a step of permitting the liner plate assemblies to stand upright in the field of construction of a spent nuclear fuel storage pool, and welding edges of the adjacent linear plate assemblies; and a step of welding vertical drain channels(300) to vertical welded parts of each of the liner plate segments.
