Nuclear reactor concrete pressure vessel liner anchors - have bulges through which water cooling tubes pass without welds

摘要

Inner wall face, comprises a concrete wall and a liner of metal, optionally with a layer of insulation between them. The liner is anchored to the structural concrete by anchors directly fixed to the liner and distributed at uniform spacing over the liner. Each anchor comprises a thickened region away from both of its ends; this thickened region contains >=1 bores, through which the cooling pipes for the vessel wall pass. Good heat conductance and transfer from liner to cooling pipes is obtained, without direct welded connection. Considerable savings in material and welding and accurate fixing and aligning are achieved. In particular, welds at high critical positions, such as cooling pipes, are virtually eliminated.
