reactor pressure中文摘要：PURPOSE:To provide an exhaust duct on the reactor running floor of a boiling water atomic power generating equipment being excellent in maintenance of environment, by a method wherein the whole surface of the lower end of a roof turus is covered with a panel for use as an exhaust duct. CONSTITUTION:A decorative laminate 9, which has exhaust ports 4 located on the central line of each of a spent fuel pool 7, a reactor well 6, and a drier separator pool 5, which are on the reactor running floor of a boiling water atomic power generating equipment, is installed to the lower part of a roof torus 10. Air exhausted through the exhaust ports 4 is forcibly exhausted through an exhaust duct 1. The exhaust duct 1 is connected directly to the decorative laminate 9. Since the whole of the roof torus in an exhaust chamber and a velocity of exhaust flow in the roof torus is low, a pressure in the roof torus is approximately specified. Thus, regulation of an airflow within the exhaust duct 1 eliminates regulation of an airflow of each exhaust port 4.
