What was used to control the heat of the reactions at Chernobyl?

As in any nuclear reactor control rods made of neutron absorbing material limit the reaction rate. However the control rods of the RBMK type reactor had a serious design error: they were tipped with several feet of graphite, the moderator which made the reaction go faster when first inserted instead of slower. This was compounded by the operators violating procedures and removing the rods completely from the core instead of keeping the graphite tips inside the core at all times.
The temperature is managed by the cooling system (and has nothing to do with the control rods) which in the RBMK uses water. The operators also violated procedures by disabling the emergency cooling system.

What is the formula used to calculate thermal energy changes?
Simply use conservation of energy. The change in an object's thermal energy is equal to any heat (thermal) energy that gets into the object, minus any heat energy that gets out of the object. If you have energy conversion, such as chemical reactions, you need to account for the increase or reduction of heat energy due to those reactions, as well.
What Metal used in nuclear reactions?
Nuclear energy appears as heat in a nuclear reactor. It comes from the fission of uranium or plutonium
How is nuclear energy transformed into thermal energy?
Nuclear Energy is harnessed in Nuclear Reactors by 'fission' reactions which produces heat (thermal energy). In productive applications it is used to heat water to produce steam to rotate turbine and generate electricity by it.
How is the heat generated by the reactor core of a nuclear power plant used to provide power to building?
Within the reactor core of a nuclear power plant all the actions and reactions take place. These reactions release energy in the form of heat. This can be harnessed to provide power to the building.
What types of rods slow down nuclear reactions?
Control rods that absorb neutrons. These contain some material that strongly absorbs neutrons, boron is most often used but cadmium has similar properties.
What are displacement reactions used to provide?
heat energy
Does freezing lose heat or add heat?
Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.
What was the chernobyl power plant used for?
what is the chernobyl power plant used for
Was chernobyl used in the movie Skyfall?
No, Chernobyl was not used in the movie Skyfall.
What is the function of a bottom flask?
It is used to heat liquids or to made chemical reactions.
What are the exothermic and endothermic reactions and how can they be used?
exothermic reactions are those that give out energy (most notably by heat) when they occur endothermic reactions require energy to take place and thus feel cold to touch as they extract heat from the surrounding environment.
What else could exothermic and endothermic reactions be used?
They could be used for making science test or other things, per example: Many chemical reactions release energy in the form of heat, light, or sound. These are exothermic reactions. Exothermic reactions may occur spontaneously and result in higher randomness or entropy (ΔS > 0) of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy (ΔH < 0). In the lab, exothermic reactions produce heat or may even be explosive.
Enzymes are used by cells to trigger and control particular chemical reactions?
Yes
What is a device that controls the rate of nuclear fission reactions?
Control rods are used.
What are the special properties of enzymes?
Enzymes reduce the activation energy of a reaction. They accomplish this feat by altering the local chemical environment of the substrates while typically bringing the reactants into close proximity and even stabilizing conformers that promote reaction.
What is using a calorimeter?
Heat is measured using calorimeter.A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity.
In nonliving systems chemical reactions can be sped up by adding?
The most common way to speed up chemical reactions in non-living systems is to add heat. Heat causes the molecules to move faster, creating more collisions. In some reactions, extra oxygen is used to speed them up.
