Studies indicate the best way to control the temperature of the endothermic reaction in a mixed reactor is through making adjustments to the coolant temperature. There processes are highly complex.

What is the effect of olefin concentration on naphtha hydrotreating process?
Hydrotreating reaction is an exothermic reaction. The total reaction provides excess reaction heat; more is produced by the exothermic hydrogenation reactions than are required to support the endothermic cracking reactions.High Olefin conc. leads to high temp. rise due to hydrogenation reaction.This excess heat increases the reactor temperature and accelerates the reaction rate. Temperature rise can be controlled by injecting cold hydrogen or cold recycled quench into the reactors to absorb excess reaction heat.
Why ceramic used for wall of a nuclear reactor?
ceramic can withstand high temperature
What is semi batch reactors?
Semi batch reactor is the one in which one reactant is charged before the reaction and the other is continously added as the reaction proceed.
What is reactor period in nuclear engineering?
Reactor period is the time is takes for a reactor's power to increase by a factor of e (2.71828).
What is an autoclave reactor?
a reactor is generally termed as an autoclave reactor,when it is a high pressure batch reactor.mostly this kind of reactors are used for sterilization the reactants..
How do you enhance rate of reaction in CSTR?
rate of a reaction can be increased by increasing the temperature if the reactor
How does the control rod affect the rate of reaction in the nuclear reactor?
A control rod is made of a neutron absorbing material. Boron is common. When the control rod is withdrawn (pulled out) of the reactor, the fission reaction rate increases. When that control rod is inserted, the reaction rate decreases. There are other factors that control the reaction rate, but the rods can be considered as the way to start up or shut down the reactor by pulling or inserting them.
The chain reaction in a nuclear reactor is controlled by inserting what?
control rods.
What control the chain reaction in a nuclear reactor?
The reason a nuclear chain reaction occurs is that one of the by products of a single reaction: the neutrons can start reactions of their own. So how do you stop a chain reaction? Stop these neutrons from causing any more reactions. This is done in nuclear reactors by placing control rods into the reactor core. These control rods are made of elements that can absorb the high energy neutrons without reacting themselves. Therefore, by moving these rods in and out of the reactor, the rate of reaction in a nuclear reactor can be easily controlled.
The temperature levels in a nuclear reactor are maintained primarily by the use of what?
The control rods which are neutron absorbers can be raised or lowered to change the reactor power level. The temperature at the reactor outlet will be a function of both the power level of the reactor and the coolant flow rate and inlet temperature.
If you wanted to slow down the chain reaction in a nuclear reactor would you remove or insert the control rods?
In order to slow down the chain reaction in a nuclear reactor, i.e. to reduce KEff, you would insert the control rods.
What is the function of an electrical reactor?
A nuclear reactor contains a nuclear reaction, provides support for the control mechanisms for the reaction, and provides for the transfer of heat to machinery that will use it to produce electric power.
What is the purpose of control rods in a nuclear reactor?
A nuclear reactor requires the neutrons released from one reaction to trigger the fission of other nuclei. Control rods are required to absorb some of these neutrons so as to prevent a runaway chain reaction.
Control rods are used in a reactor core to?
Reactor control rods are made of a substance that absorbs neutrons.
What would happen if the control rods were removed from the reactor core?
Typically the reaction rate increases.

In a nuclear power plant fission reactions are controlled by inserting what?
In a fission reactor, control is implemented by inserting control rods into the reactor. These are made of a material that absorbs neutrons, and prevents a reaction from taking place.
