The utility model relates to a fuel transfer tube shield for two reactors. The fuel transfer tube shield comprises shielding structures arranged between a fuel building and containments, shielding structures between the containments and refueling water tanks and shielding structures between inner and outer shells of the containments, wherein upper-layer and lower-layer floor slabs of a floor where the parts, between the outer sides of the containments and the fuel building, of fuel transfer tubes are located are adopted as shielding layers of the upper and lower sides of the parts, and labyrinth type shielding bodies are adopted for the two horizontal sides of the parts; upper-layer and lower-layer floor slabs of a floor where the parts, between the inner sides of the containments and the refueling water tanks, of the fuel transfer tubes are located are adopted as shielding layers of the upper and lower sides of the parts, the relatively narrow one of the two horizontal sides of each part is completely sealed by a shielding body, and a labyrinth type shielding body is adopted for the relatively wide side; labyrinth type shielding bodies are adopted for the four sides of the parts, between the inner and outer shells of the containments, of the fuel transfer tubes. The fuel transfer tube shield is easy to implement and low in construction cost and has good shielding effects, and effective radiation safety guarantee can be provided for personnel and equipment around the fuel transfer tube shield.
