SATURATED VAPOR SUPPLY SYSTEM FOR TESTING STEAM TOUCHED VALVE OF NUCLEAR POWER PLANT

摘要

PURPOSE: A saturated steam supply system for vapor system valve ability testing device of an atomic power plant is provided to simply and efficiently design by using pressure of saturated steam. CONSTITUTION: A saturated steam supply system comprises a vapor storage tank (200), a vapor supply valve (300), and a water tank (500). The vapor storage tank stores saturated steam supplied to a valve mounting instrument (900) for testing. The vapor supply valve is comprised of a first vapor supply line (210) which supplies saturated steam to the valve mounting instrument for testing and a second vapor supply line (220), and controls supply of saturated steam. The water tank (500) is connected through the first vapor supply line and the vapor connection line and supplies high pressure water to the second vapor supply line through a supply line (710). A control valve (700) is comprised to be installed on the supply line. [Reference numerals] (200) Vapor storage tank; (310,800) Controller; (610) Temperature controller
