Pressurizer relief tank

01 Civilian Nuclear Power Equipment Series:

In the context of promoting a low-carbon, high-efficiency energy system, China is vigorously developing nuclear power to achieve the dual goals of energy security and environmental protection. As a crucial part of clean energy, nuclear power plays a significant role in reducing greenhouse gas emissions, reaching carbon peaking and carbon neutrality targets.

Shandong Beichen Electric Equipment Co., Ltd., as a leader in the domestic production of nuclear-grade equipment, has been committed to technological research and innovation in nuclear power equipment since 2008. The company’s products cover third-generation nuclear power technologies such as “Hualong One” and “Guohe One,” as well as fourth-generation nuclear power technologies like “Fast Reactor” and “High-Temperature Gas-Cooled Reactor,” providing key equipment for many nuclear power plants in China. Beichen has gained high recognition from major nuclear power companies such as CNNC and CGN for its excellent products and reliable services.

Technological innovation is the core of Beichen's development. In 2014, the company undertook the 821 high-level radioactive liquid vitrification project, successfully achieving the localization of key equipment and setting a new milestone in the development of nuclear waste processing technology in China. Beichen’s achievements in the field of nuclear-grade equipment manufacturing have not only enhanced its competitiveness but also made positive contributions to the nation’s energy strategy and environmental protection.

02 Civilian Nuclear Power Products-Pressurizer relief tank

The pressurizer relief tank is a key safety device in the primary loop system of a nuclear power plant. Its main uses and features are as follows:

1.Purpose:

1.1.Pressure protection: When the pressure of the reactor coolant system (primary loop) exceeds the set safety limit, the pressurizer pressure relief tank can quickly release excess pressure to prevent system overpressure and ensure the safe operation of the nuclear power plant.

1.2.Receive steam and water: In an emergency, receive steam, non-condensable gases and water discharged from the pressurizer to stabilize the pressure of the system.

2.Features:

2.1.Thick shell: The shell thickness reaches 42mm, which can withstand extreme working conditions and ensure the firmness and durability of the equipment;

2.2.Large tonnage design: The equipment weighs about 40 tons and has a large volume, which can effectively handle a large amount of emissions and ensure that the system pressure is controlled in time;

2.3.High reliability: The use of advanced design and materials ensures reliable performance in emergency situations and meets strict nuclear safety standards;

2.4.Multiple safety mechanisms: Equipped with a variety of safety devices, such as pressure sensors and automatic valves, to ensure that it can respond quickly and perform pressure relief operations when needed.
