STEAM GENERATOR AND TUBESHEET

摘要

PURPOSE: Steam generator and tube sheet are provided to reduce manufacturing time by removing welding engagement between forged products. CONSTITUTION: A steam generator includes a bod, a heat pipe, a tube sheet (130), a stay cylinder and a stay cap (132). The body forms the exterior of the steam generator. The heat pipe flows within the body and supplies a high-temperature primary coolant. The tube sheet supports the heat pipe. The stay cylinder supports a separation plate partitioning a secondary coolant being vaporized by exchanging heat with the primary coolant of the heat pipe. The stay cap is configured to connect the stay cylinder to the tube sheet. The stay cap is integrally formed with the tube sheet.
