A Chinese chip

Nuclear fuel assemblies are like the "energy treasure trove" of nuclear power plants, containing nuclear fuels like uranium-235 that continuously release large amounts of energy through nuclear fission and chain reactions. The control rod is the "magic wand" that controls nuclear reactions, made of materials like boron and cadmium that are very good at "eating" neutrons. When we want to increase the power of the nuclear reaction, we lift the control rod upwards. This way, the neutrons absorbed by the control rod are reduced, and more neutrons can collide with the uranium-235 nucleus, making the nuclear fission reaction more intense and releasing more energy. Vice versa. As a third-generation nuclear power technology independently developed by China, Hualong One has complete independent intellectual property rights in equipment design, fuel components, software construction, operation and maintenance. Its unique "177 core" design is also a result of Chinese independent innovation, and is therefore vividly called a "Chinese core". The '177 core' refers to the Hualong No.1 reactor.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

1. Selection and arrangement of nuclear fuel: Nuclear reactors use heavy nuclear materials such as uranium-235 as fuel, which are made into fuel rods and arranged in a specific pattern in the reactor pressure vessel. Uranium-235 is a material that is prone to fission due to neutron impact. When struck by a neutron, uranium-235 splits into two lighter atomic nuclei and releases energy and neutrons. These released neutrons further impact other uranium nuclei, triggering a chain reaction. 2. Generation and application of steam: High temperature and high pressure steam is sent to a steam generator, and heat is transferred to external water through heat transfer tubes, turning it into steam. These vapors are then directed to the steam turbine, which drives the turbine to rotate and in turn drives the generator to generate electrical energy. This process is the core step of a nuclear reactor converting nuclear energy into electrical energy.
