The invention discloses a 1460mm moving blade for a half-rotating-speed nuclear power turbine, relates to a high-power half-rotating-speed nuclear power turbine moving blade and aims to solve the problem that turbine moving blades meeting requirements of a mega half-rotating-speed nuclear power unit do not exist in the prior art. Lug boss lacing wires are positioned in the middle of a blade working part; the molded lines of the blade working part are cross-section-variable twisted blades; the cross-section area from the root to the top of the blade working part is gradually reduced; a Stellite alloy piece is attached to the air inlet side of the upper part of the blade working part; the height of the blade working part is 1460mm; the root axial width of the blade working part is 268mm; the root diameter of the blade working part is 2750mm; the exhaust steam area of the blade working part is 19.31m<2>; the axial width of a blade root is 320mm; the thickness of a lashing strip is 30mm; the axial distance of the working surface of the lashing strip is 80mm. The 1460mm moving blade is applied to a half-rotating-speed nuclear power turbine unit with the power of 1000MW.
