The basic composition of an industrial reactor and its safety and security
Apr 28, 2018

There are many types of industrial reactors, but no matter which type mainly includes several components such as active area, reflective layer, outer pressure shell and shielding layer. The active area of an industrial reactor is again composed of fuel, moderator, coolant and control rods. Its main feature is the use of low-cost, widely available ordinary water as a moderator and coolant.

 

Moreover, in order to keep the cooling water in the industrial reactor at a high temperature, the reactor is operated under high pressure. Since the water in the industrial reactor is in a liquid state, the steam for driving the turbine generator must be generated outside the industrial reactor. This aspect has to be realized by means of a steam generator. The cooling water from the industrial reactor, ie the primary circuit water, flows into one side of the steam generator heat transfer pipe and transfers the heat to the secondary circuit water on the other side of the heat transfer pipe. The latter turns into steam.

 

Because industrial reactors use ordinary water as moderators and coolants, the thermal neutron absorption cross section is relatively large, so the requirements for fuel are also very high. Boiling water reactors and pressurized water reactors belong to the same light water reactor. Like pressurized water reactors, they also use ordinary water as moderators and coolants. The difference is that steam is generated in the boiling water reactor and directly enters the gas turbine to generate electricity without steam. The generator also has no distinction between primary and secondary circuits. The system is particularly simple and the working pressure is lower than that of pressurized water reactors.

 

Compared with similar equipment in the past, industrial reactors have high energy concentration, low fuel costs, and good overall economic benefits. And because of the small amount of fuel required, it is not subject to restrictions on transportation and storage. At the same time, industrial reactors will not cause excessive pollution to the environment, so it will not emit harmful gases such as CO, SO2, NOX and solid particles during operation, and will not emit carbon dioxide that produces greenhouse effect.

 

What deserves more emphasis is the safety of industrial reactors. It does not explode on the one hand because of the safety of the fuel it uses; on the other hand, because industrial reactors contain control rods made of materials that absorb neutrons easily. The speed of the fission reaction is controlled by adjusting the position of the control rod.

 

Not only that, the addition of coolant can continuously bring out the enormous heat generated by the fission reaction in the industrial reactor, so that the temperature within the industrial reactor is controlled within the required range, so it will not cause damage due to high heat. In short, industrial reactors are safe, environmentally friendly, and highly efficient reaction equipment.http://www.wxlsshzb.com/
