Abstract
(EN)
The invention relates to a pressure stabilizer of an integral reactor. The pressure stabilizer of an integral reactor includes a container, and also includes a partition board, and the container can form an airtight pressure stable space through the partition board. The upper part of the airtight pressure stable space is a steam chamber, and the part below the steam chamber is a water chamber. A plurality of heating elements run through the side wall of the container. The partition board is provided with a first class surge pipe and a second class surge pipe. The first class surge pipe is communicated with the water chamber and a lower reactor coolant, and the first class surge pipe is provided with a valve body. The second class surge pipe is communicated with the lower reactor coolant and the steam chamber. The pressure stabilizer provided by the invention is suitable for an integral reactor, has a simple structure and complete functions, not only can realize pressure regulation, but also can reduce additional pipeline setting, and satisfies equipment integration, modularization and other requirements.
