A bulk (slurry) polymerisation reactor which is made of a closed long tube through which the slurry is circulated. Loop reactors are characterised by a very narrow residence time distribution, leading to uniform product characteristics.
a completely mixed reactor. the concentration in the reactor is the same that flows our of the reactor
I believe it is: Loop condition Loop actions And how the loop breaks
A counted loop is a loop that executes the loop's statement a pre-determined number of times. The count represent the exit condition of the loop. A loop that is not counted is an infinite loop.
You may mean FBR - this stands for Fast Breeder Reactor
Experimental Breeder Reactor I was created in 1950.
A nuclear reactor has two coolant loops to prevent radioactive contamination. The primary loop cools the reactor core to generate power, while the secondary loop transfers heat to produce steam for electricity generation. This dual-loop system ensures that radioactive material from the core does not mix with the water used to generate electricity.
The steam generated in a nuclear reactor is used to turn a turbine, which in turn drives a generator to produce electricity. After passing through the turbine, the steam is condensed back into water in the condenser before being pumped back to the reactor as part of the cooling loop.
Nuclear reactor heats water making steamTurbines are turned by steamCooling tower condenses spent steam back to waterwater is returned to the nuclear reactorIts actually a bit more complicated than this single closed loop, because the water heated by the nuclear reactor itself becomes slightly radioactive. Because of this radioactivity, for safety reasons a system with two closed loops connected by a heat exchanger is used. In the primary loop the water just keeps circulating between the nuclear reactor and the heat exchanger. In the secondary loop the water circulates as in the steps listed above, but substitute Heat exchanger for Nuclear reactor.
The primary difference between a pressurized water reactor (PWR) and a boiling water reactor (BWR) is that in the BWR, water is actually boiled, and the steam is used to drive a steam turbine, while in the PWR, the primary coolant is not allowed to boil, but is circulated in a closed loop to boil water in a steam generator. The BWR circulates primary coolant through the steam turbine in a closed loop. The PWR contains the primary coolant in a loop that includes the steam generator, and not the steam turbine.
The pressurized water reactor (PWR) is a type of nuclear reactor where water is used as both a coolant and moderator. The reactor core heats up the water, which remains under high pressure to prevent it from boiling. This hot water then passes through a steam generator, where it transfers its heat to a separate secondary water system, creating steam to drive a turbine and generate electricity. The neat sketch of a PWR typically shows the core surrounded by the primary coolant loop and the secondary steam loop connected to the turbine generator.
Reactor coolant water is kept contained in the primary loop to prevent contamination of the surrounding environment in case of a leak or accident. Mixing it with feed water or allowing it to leave through the cooling tower would increase the risk of radioactive release. Keeping it contained also helps maintain a closed system for efficiency and safety.
I suppose you mean the three separate cooling loops? This gives redundancy which means that in an accident where one loop might be disabled, there is still adequate reactor cooling available. New reactors have four loops to provide even greater redundancy (and to cope with increased reactor output)
In a nuclear power plant, water is typically used as the coolant and moderator in the primary loop. The heat from the reactor core is transferred to the water in the primary loop, which then goes through a heat exchanger to transfer the heat to a separate water loop in the secondary system. This secondary loop is used to drive a turbine and generate electricity.
In a PWR the pressure in the reactor primary circuit is kept high enough to prevent boiling, and heat is transferred to a secondary circuit at a lower pressure where steam is produced for the turbine. In a BWR a proportion of the water passing into the reactor is allowed to boil off feeding directly to the turbine. Otherwise, the reactor core itself is very similar.
It means that:* There is water, and * It is under higher pressure than normal, i.e., more than 1 atmosphere (or bar) of pressure. At higher pressures, water can achieve a higher temperature (i.e., higher than 100 degrees Celsius) before it boils.
