REACTOR STRUCTURE INNER TYPE REFUELING WATER STORAGE TANK FOR NUCLEAR FUEL OF NUCLEAR POWER PLANT

摘要

PURPOSE: A reactor structure is provided to be capable of using an outer wall of the reactor structure as a wall of a refueling water tank. CONSTITUTION: An outer wall(30) of a reactor structure(10) is configured to support a roof stood on a fundamental part(20). A concrete water tank wall(42) is stood on the fundamental part(20) to be spaced apart from the outer wall(30) and constitutes the edge of a water tank space(45) between outer walls(30). A concrete sleeve(43) is supported by the outer wall and the water tank space(42). A water tank frame(44) is attached to the sleeve(43), the water tank wall(42), the outer wall(30) and the fundamental part(20) and constitutes a shield surface for maintaining an airtightness of the water tank space(45).
