HYDRAULIC CAPACITY FOR A PASSIVE SYSTEM OF EMERGENCY EMPLOYMENT OF A NUCLEAR REACTOR

摘要

1. Hydraulic reservoir for a passive system of emergency flooding of a nuclear reactor with an upper inlet pipe for a vapor-gas mixture and lower main and additional drain pipes for water, the lower outer ends of which are connected to each other, with a device installed inside the hydraulic reservoir housing for stepless flow profiling, made in the form of a vertical partitions along the entire height of the tank body with an opening for water passage, the flow area of which decreases from top to bottom, while the lower drain pipes are located on opposite sides of the partition. 2. The hydraulic reservoir according to claim 1, characterized in that a larger volume of the vessel body, divided by a partition, is connected to the upper inlet pipe for the steam-gas mixture and an additional lower drain pipe, and a smaller volume of the container body is connected to the main lower drain pipe. 3. The hydraulic reservoir according to claim 2, characterized in that a diaphragm is installed in the lower additional drain pipe between the body of the hydraulic reservoir and the junction of the lower outer ends of the drain pipes. 4. The water tank according to claim 1, characterized in that the opening for the passage of water in the partition is a vertical slot of variable profiled width. Hydraulic reservoir according to claim 3, characterized in that the partition can be made composite. 6. The reservoir according to claim 1, characterized in that the opening for the passage of water can be formed by the gaps between the body of the reservoir and the partition of variable width. Hydraulic reservoir according to claim 1, characterized in that the hole for the passage of water is a set of holes, the total area of which is
