This is going to be a big number! Each fission releases 200 MeV, and 1 MeV = 1.6 X 10-13 Joules, so 1 fission = 3.2 x 10-11 Joules. Now if the thermal power produced by the reactor is 3000 MW (corresponding to an electrical output of 1000 MW) this means 3000 x 106 Joules per second, or 3 x 109 Joules /sec. So the number of fissions/sec in the reactor is 3 x 109 divided by 3.2 x 10-11 , so if we call 3/3.2 = unity, for simplicity, the number of fissions per second is 1020. I said it would be big!

Reactor physicists use a number called the neutron flux to describe the intensity of the nuclear fission process, this is the number of neutrons crossing an area of 1 sq cm per second. This number helps to define the fuel rating and effects on reactor components in the active core. Obviously the total number of fissions occurring in the reactor overall per second depends on this and the size of the reactor.

How many control rods are there in a nuclear reactor?

The number of control rods in a nuclear reactor can vary depending on the design and size of the reactor. Typically, a nuclear reactor can have anywhere from 50 to 100 control rods. These rods are used to control the rate of the nuclear reaction by absorbing neutrons and regulating the power output of the reactor.

When a few atoms undergo fission, they cause many more atoms to split; this process is called an atomic bomb.


How many years is the useful life of a nuclear fission reactor?

The useful life of a nuclear fission reactor is typically around 40-60 years. However, this can vary depending on factors such as maintenance, upgrades, and regulatory approvals.


In nuclear reactor how will you say control rods absorbs only one neutron?

Control rods are made of materials that readily absorb neutrons, such as boron or cadmium. These materials have a high neutron absorption cross section, which means they are very likely to absorb a neutron when it comes in contact with them. The design and placement of control rods in a nuclear reactor are carefully engineered to ensure that they absorb just enough neutrons to control the rate of the nuclear reaction without completely stopping it.


What is the smallest nuclear reactor?

Nuclear reactors can be as small as a single room. There are many reactors that are less then 30 MW (a typical reactor is around 1,000 MW), and consider that a normal car engine is about 200 KW (or .2 MW) so some reactors produce the power of only about 100 cars. The smallest that are standardly used, other then for research, are found on submarines.

What is the source of energy in nuclear reactor?

The source of energy in a nuclear reactor is the release of binding energy, i.e. the binding energy that hold protons and neutrons together in the nucleus of the atom. Heavy nuclides, such as uranium, are split into lighter nuclides, such as cesium and barium (and many others, in a semi-random cross section). The binding energy required to hold the original uranium together is less than the daughter products and is released to the system in the form of heat and other radiation.

How many watts does a nuclear reactor put out?

The power output of a nuclear reactor can vary widely, depending on the design and size of the reactor. Commercial nuclear power reactors typically have power outputs ranging from 500 megawatts (MW) to over 1,500 MW.


Where is the source of nuclear energy found?

Nuclear energy is gained from atoms of any kind, thus the name 'Nuclear'. We generally only use heavy, radioactive atoms for nuclear energy though, as they contain lots of energy and are easier to split than others typically. The most common element used in Nuclear Energy plants is Uranium, which is mined naturally in many world locations.


How many pounds of uranium are in a nuclear reactor?

The quantity depends on: the type of the reactor, power of the reactor, enrichment of uraniu, chemical form of the fuel, etc. For a research reactor some kilograms, for a power reactor more than 100 tonnes/year.
