Embodiment Construction

[0027] figure 1 Shown is a schematic longitudinal sectional view of a nuclear reactor, such as a steam generator 2 of the European Pressurized Water Reactor (EPR) type. The steam generator 2 has a container 4 that is hermetically closed with respect to the external pressure, in which the primary medium P-here mainly water-is located during operation. In the lower part of the container 4, the primary medium P is in a liquid state, that is, in the liquid phase 6. According to the current operating conditions, a part of the liquid phase 6 evaporates, and a vapor phase 8 is formed in the upper part of the container 4.

[0028] For reliable operation, it is stipulated that the material level or liquid level (with liquid level height h) of the liquid phase 6 in the container 4 shall not be lower than the predetermined minimum material level on the one hand, and shall not exceed the predetermined maximum material level on the other hand. Bits, in other words, move within the range or ...

Abstract

The invention relates to a passive fill state regulating system comprising the following - a container (4) which receives a primary medium (P), said primary medium (P) having a liquid phase (6) and asteam phase (8) in the container (4) during operation, - a primary medium (P) supply line (10) which is connected to the container (4) and into which a regulating valve (14) is connected, and - a standpipe (18, 18') which is connected to the container (4) as communicating pipes and through which the primary medium (P) flows. A part of the standpipe (18, 18') forms the primary side of a heat exchanger (20), the secondary side of which has a secondary line (30) that receives a secondary medium (S), wherein a pilot valve (16) which acts on the regulating valve (14) is connected into the secondaryline. The invention is characterized in that the heat exchanger (20) has an elongated heat exchanger surface (32) which is largely vertically aligned, and the pilot valve (16) and / or the regulating valve (14) can be adjusted continuously such that the flow through the supply line (10) continuously varies with the fill state of the liquid phase (6) in the container (4).

Description

Technical field [0001] The invention relates to a passive material level adjustment system with the features of the preamble of claim 1. [0002] Therefore, the present invention is based on a passive material level adjustment system with: [0003] · A container containing a primary medium, wherein the primary medium in the container has a liquid phase and a vapor phase during operation; [0004] · A feed line for the primary medium connected to the container, and a regulating fitting (Regelarmatur) is connected to the feed line; and [0005] ·As a riser pipe connected to the container as a connecting pipe and can be flowed through by the primary medium, [0006] Wherein, the standpipe forms the primary side of the heat transfer device in a partial section, and the secondary side of the heat transfer device has a secondary pipeline containing the secondary medium, and the secondary pipeline is connected to the adjustment fitting The pilot valve. Background technique [0007] In nuclear...
