How the Cooling Systems in a Nuclear Power Plant Work.
Most people do not understand how the cooling systems in a nuclear power plant work. However, all of us should know that this is absolutely critical for safety reasons. The cooling system also ensures that the overall functioning of the reactor system is not affected by hot water that is heated up due to the reactor system.
The cooling systems in a nuclear power plant are critical and are used to provide sufficient air cools the system that is used to convert heat into steam to turn a turbine. Thus, no matter what happens, the cooling system of the nuclear power plant remains intact. This system helps in minimizing the effects of the steam explosion due to the sudden shutdown of the nuclear reactor that is now in use.
Starting and stopping of the nuclear reactor is performed with the help of the PWRs and PSUs. The first step to understanding how the PWRs and PSU's work are to know the temperature of the water that is placed in the reactor vessels that are used to keep the core of the reactor to be cooled. This is accomplished through the circulation of water and cooling them through the core of the reactor. Radioactivity, as everyone is aware of, means that radioactive elements decay into another element. In atomic reactors, the fission of uranium atoms produces lots of heat that creates heat to steam.
The pressure inside the reactor vessel increases to a very low level once the core has reached a low-pressure state. The process of circulation, which is initiated by using pumps or the use of gravity to pump water into the reactor vessel, helps in drawing the water out and increasing the pressure. This, in turn, activates the starter of the reactor.
Once the starter valve is activated, the starter motor or some other circuit activates the electric motors that start the turbine. This is done with the help of the control panel of the reactor that uses the pulse of energy coming from the reactor. The most important thing that is being used to initiate the electric motors is called as the generator. This is called as the PWR and it is used to turn the electric motors.
It is quite obvious that there is a system that shuts down the reactor system that can be used to shut down the starter system of the reactor system. However, before it does that, it will send out an alarm to tell the operator that the reactor is already shutting down. This is done in a time-tested manner to prevent any leakage of radiation.
Once the reactor reaches the full-power state and starts to shut down, the water will heat up and the reactor will start leaking radioactive materials and once the water level in the reactor rises to a certain level, it would take a long time for the water to be cleaned up and clear-off properly. To overcome this problem, the water is pumped out of the reactor and stored in a form of liquid sodium. After cleaning up the water and disposing of the radioactive materials, the water is re-injected back into the reactor.
Understanding how the cooling systems in nuclear power plant work should help us to protect ourselves from the radioactive materials that the water is coming from. Hence, if we need to shut down the reactor, it should be done with the help of these cooling systems and the PWR or the PSU to avoid any harm to our health.
