In-containment refueling water tank having rinsing function

摘要

An in-containment refueling water tank having a rinsing function, consisting of an in-containment refuelling water tank 1 and a rinsing pool 2 arranged side by side. The in-containment refuelling water tank is linked to the rinsing pool through a water injecting pipeline 3 on the bottom and an overflow pipeline 5 below the upper water level; and a gas-intake pipeline 6 connected to the atmosphere of the containment and a gas-exhaust pipeline 8 connected to a filtering and exhausting system of the containment are provided in the rinsing pool. This adds an extra rinsing function while guaranteeing the function of the in-containment refueling water tank. A check valve 4 may be mounted on the water injecting line, so that water can only flow into the rinsing pool. The gas intake pipeline may be exposed to the atmosphere of the containment at one end and connected to a bubbler 7 at the lower end. An exhausting micro-pore 9 may be formed within the rinsing pool.
