Generally, it is required to graduate from a university majoring in nuclear engineering and technology (generally not a graduate student), pass the comprehensive tests of nuclear power companies (such as CNNC, China Guangdong Nuclear Power Corporation, China Power Investment Corporation, etc.), the initial test, re-examination and physical examination (strict, color-blind and weak), and then enter the nuclear power plant for study and training until passing the operator examination of the National Nuclear Safety Administration.
Supplementary information:
Daya Bay Nuclear Power Station had many specialties last year. Yes, college degree or above is ok. Mainly good health, personality meets the requirements of power station posts, which is the most important point. There is no requirement for band 6, but there seems to be one for band 4.
Extended data:
Nuclear power plant, that is, nuclear power plant, is a kind of thermal power plant that uses nuclear reaction as heat source, drives steam turbine engine and connects generator to generate electricity.
Nuclear power plants are energy-efficient buildings, with almost zero emissions of greenhouse gases and carbon dioxide, but the construction cost, technical requirements and maintenance costs are also high. Under the conditions of good surrounding control and perfect emergency system, nuclear power plants are actually quite safe facilities.
First of all, a brief introduction.
1, a power station that uses nuclear energy to generate electricity is called a nuclear power station. In today's world, only the energy generated by fission chain reaction can be used to generate electricity.
2. A nuclear power plant is a power facility that uses the heat energy generated by one or several power reactors to generate electricity or generate electricity and heat. Reactor is the key equipment of nuclear power plant, and the chain reaction of nuclear fission is carried out in the reactor. Systems and facilities that convert nuclear energy released by nuclear fission into heat energy and then into electric energy are usually called nuclear power plants.
3. The reactors commonly used in nuclear power plants in the world include light water reactor, heavy water reactor, improved gas-cooled reactor and fast reactor, but light water reactor is the most widely used. According to the different steam generation processes, light water reactors can be divided into boiling water reactors and pressurized water reactors. Pressurized water reactor (PWR) uses ordinary water as coolant and moderator, which is the most mature and successful power reactor developed from military reactor. Pressurized water reactor nuclear power plant accounts for more than 60% of the total nuclear power capacity in the world.
The fuel used in nuclear power plant is uranium. The nuclear fuel made of uranium fission in the equipment of the "reactor" produces a large amount of heat energy, and then the heat energy is taken out by water under high pressure, and steam is generated in the steam generator, which drives the steam turbine to rotate with the generator, continuously generating electricity and transmitting it to all directions through the power grid.
Second, principles.
1, nuclear power plant is the use of atomic nuclear fission reaction to release energy, energy conversion and power generation. The working principle of PWR nuclear power plant is expounded.
2. In PWR, nuclear fission self-sustaining chain reaction of nuclear fuel nucleus produces a lot of heat. Coolant (also known as heat carrier) brings the heat in the reactor into the steam generator and transfers it to its working medium-water, and then the coolant is transported back to the reactor by the main circulating pump for recycling, thus forming a loop called the first loop. This process is also an energy conversion process in which nuclear fission energy is converted into heat energy.
3. The working medium on the secondary side outside the U-shaped tube of the steam generator is heated and evaporated to form steam, which enters the steam turbine to expand and do work, and the heat energy released by the enthalpy drop of the steam is converted into mechanical energy for the rotation of the steam turbine rotor. This process is called the energy conversion process from thermal energy to mechanical energy. The steam that does work condenses into condensed water in the condenser and returns to the steam generator to form another circulation loop, which is called the second loop. This process is called the energy conversion process from thermal energy to mechanical energy. The rotating rotor of the steam turbine directly drives the rotor of the generator to rotate, so that the generator generates electric energy, which is an energy conversion process from mechanical energy to electric energy.
